iii Technical Proposal for Consultancy Services | Kensetsu Kaihatsu Limited

Executive Summary

In order for the Vision to be realized within the designated time-frame, it is

imperative that the targeted economic growth is achieved through rapid

industrialization, enhanced agricultural production and agro-industry development,

booming tourism, advanced education (science and technology) among other factors.

Such goals can only be achieved through rapid infrastructure development based on

innovative techniques, methods and technologies as a primary driving factor.

In the Keynote Lecture and Publication by Mukabi on “The Role of Enhanced

Research in Geotechnical Engineering for Pragmatic Infrastructure Development

within the Vision 2030”; Published in the Proceedings of the 2008 Institution of

Engineers of Kenya International Conference on “The Engineer and Vision 2030”,

innovative methods that can realize the practical achievements of such advancement

are discussed in terms of cost-effectiveness, performance and environmental

considerations. In order to achieve these fundamental goals, the paper also

emphasizes the need to enhance capacity building programmes through the pragmatic

development of strong Young Engineers Programmes (YEPs) for public, private and

academic institutions through technology transfer, technical training and Research &

Development activities.

This Proposal suggests and emphasizes on the utter need of enhancing Research &

Innovation for Sustainable Development (RISD) in infrastructure as a top priority area

which will form the integral technological pillar and foundation for rapid

industrialization leading to the targeted socio-economic development.

Specifically, emphasis is made on the importance of designing and implementing

Research Regimes that concentrate on developing Value Engineering (VE) technologies

and materials science that would lead to appreciable cost-time savings, whilst

enhancing the structural and serviceability levels as well as the overall performance

of the structures.

Examples of some of the VE technologies that have been recently developed and

effectively applied on roads and runway pavements, airports construction, pad

foundations for oil exploration and drilling rigs, subgrade ground improvement for

pavement structures, foundation ground improvement for bridges, jetties and other

port facilities as well as slope stabilization and structural enhancement of retaining

walls are presented in Section 3.4 and their areas of application outlined in Section

3.5 of Chapter 3.

On the other hand, case examples of the successful application of these VE

technologies within the East and Central African Region realizing average cost savings

of between 30 and 60%, time savings of more than 100% and structural enhancement

of more than 1.8 times of the conventional designs, are cited in Section 3.6 and

analysis of their performance demonstrated in one of the most recent publication on

this topic submitted by Mukabi (2012), and internationally peer reviewed and

accepted for publication in the proceedings of the ISSMGE-TC 211 International

Symposium on Ground Improvement IS-GI Brussels June 2012 entitled “Case Study

Analysis of OPMC Improved Foundation Ground, Pavement and Other Geo-

structures Employing the GECPRO Model”.

The publication, which is included in Section 3.6 of Chapter 3 of this Proposal, also

cites the research oriented unique designs of the Isiolo Airport, which is one of the

flagship projects of the Kenya Vision 2030, that were developed by Kensetsu

Kaihatsu Limited with Mukabi as the Lead Researcher/Consultant and Team Leader.

The basic format of this proposal provides Chapter 1 which is an introduction of the

fundamental role and importance of infrastructure development as an integral pillar

and foundation of achieving the Kenya Vision 2030, whilst citing the practical example

of a Research & Development Technical Proposal recently submitted to the Materials

Testing & Research Department of the Ministry of Roads.

Brief notes linking research to infrastructure development are provided under Section

1.4 whilst Section 1.5 outlines some important components and suggestions on the

basic mode of pragmatically achieving some of the goals and objectives.

An attempt is made in Chapter 2 to demonstrate the appreciation, interpretation and

response to the requirements of the “Call for Submission” by the NCST and the

objectives thereof.

A brief introduction and discussions are presented in Chapter 3, whilst Chapters 4, 5

and 6 provide examples of the technical approach and methodology designed to

achieve the research goals and objectives, performance oriented work plan and

organization and staffing respectively.

The conclusions and recommendations are outlined in Chapter 7 followed by

Attachments.

1 Chapter 1 Introduction | Kensetsu Kaihatsu Limited

Chapter 1 Introduction

1.1 Role of Infrastructure Development in the Pragmatic Achievement of Vision 2030

Infrastructure development is the heart and key to any visionary and pragmatic socio-economic growth of a country. The Kenya Vision 2030 aims at maintaining a sustained economic growth of 10% p.a. over the next 25 years through the direction that the Vision Strategy be accompanied with realistic and concrete action plans since expiry of the Economic Recovery Strategy (ERS) in December 2007. The overarching component of the Vision is that Kenya transforms into a globally competitive and prosperous nation with a high quality of life by 2030. Nevertheless, the major question still remains; how can this vision actually be achieved in reality? In order for the Vision to be realized within the designated time-frame, it is imperative that the targeted economic growth is achieved through rapid industrialization, enhanced agricultural production and agro-industry development, booming tourism, advanced education (science and technology) among other factors. Such goals can only be achieved through rapid infrastructure development based on innovative techniques, methods and technologies as a primary driving factor. In the Keynote Lecture and Publication by Mukabi on “The Role of Enhanced Research in Geotechnical Engineering for Pragmatic Infrastructure Development within the Vision 2030”; Published in the Proceedings of the 2008 Institution of Engineers of Kenya International Conference on “The Engineer and Vision 2030”, innovative methods that can realize the practical achievements of such advancement are discussed in terms of cost-effectiveness, performance and environmental considerations. In order to achieve these fundamental goals, the paper also emphasizes the need to enhance capacity building programmes through the development of strong Young Engineers Programmes (YEPs) for public, private and academic institutions through technology transfer, technical training and R&D activities. The versatility of advanced research based Consolidation and Shear Stress Ratio (CSSR) Functions

in the prediction of ground, pavement and foundation behaviour is also demonstrated. It further

proposes that the application of CSSR Functions in F.E analysis or other constructive models may

reduce the complexity of the models and/or number of parameters required in such modelling.

Further demonstration on the application of CSSR Functions in relation to the design of

appropriate testing, experimental and research regimes through the conceptual correlation of

loading rates, reconsolidation, aging, geomaterial characteristics, ground structure and re-

constitution in relation to multi-stage construction of embankments and foundations, precise

determination of bearing capacity factors numerical computerized modelling and prediction of

ground and foundation behaviour, as well as the overall enhancement of engineering parameters.

The Paper also introduces and discusses some recently developed research oriented geotechnical

engineering solutions to problems related to tropical problematic soils and recommends

appropriate methods of design and construction that would ensure the application of such

geomaterials. The ongoing research regarding this topic is also introduced.




The strength and deformation characteristics derived from the interaction of geosynthetics and

tropical geomaterials are discussed from a scientific and engineering perspective.

Recently developed techniques and geotechnical engineering concepts for ground improvement,

OPMC Stabilized retaining walls and enhancements of design, construction and maintenance

engineering aspects are also introduced.

The paper demonstrates and concludes that for purposes of achieving the Kenya Vision 2030,

sustainable development and maintenance, Research and Development (R&D) is absolutely

necessary.

1.2 Brief Introduction of Relevant Experience of Proponent Researcher (Dr. Mukabi) Since his return from Japan, Dr. Mukabi has innovatively employed the high-tech knowledge he gained overseas to undertake comprehensive research in East and Central Africa for the past 16 years, developing Value Engineering (VE) - cost – time saving technologies that are relevant for the environmental conditions, and consider optimum utilization of the natural and human resources available; ultimately contributing to integrated and socio-economic development through the cost savings realized and ploughed back in the Projects. Some of the technologies that he has developed, which realize cost-savings of between 30 and 60% depending on the nature of the works, environment and efficiency of contractor, are presented under Section 3.4, whilst their areas of application and case examples are given in Sections 3.5 and 3.6 respectively. As can also be noted from his curriculum vitae, he is a strong proponent and promoter of research based design having published over 200 scientific and engineering international publications as the first author.

1.3 Practical Example of Recently Submitted Infrastructure Research & Development Technical Proposal and the Importance thereof Kensetsu Kaihatsu Limited, with the Proponent Researcher as the Lead Research Consultant, submitted Technical and Financial Proposals to the Materials Testing and Research Department (MTRD) for research consultancy services for the following priority areas within the Ministry of Roads regarding the introduction and application of research based advanced technologies on the following main topics.

1.4 Brief Notes on Linking Research to Infrastructure Development




A network matrix mode of integrating various physical infrastructures would be recommended as a means of designing and developing a feasible and effective Research Regime.

A. Infrastructure

Sustainable infrastructure development requires:

1. Application of appropriate and suitable technologies for design and construction.

2. Cost-time effectiveness based on Value Engineering principles, technologies and policies.

3. Comprehensive feasibility studies (F/S) based on State of the Art Guidelines, Specifications

and Design Manuals.

4. Proper but pragmatic policies governing a systematic implementation system of infrastructure

that takes into account the physical and social environmental factors and constraints as

dictated by demographic dynamics and environmental changes.

B. Research

On the other hand, intensively, comprehensively and innovatively undertaken research generally

leads to:

1. Development of appropriate, sustainable and advanced technologies for design and

construction replacing archaic and outdated technologies.

2. Determination of suitability and relevance of the technologies to be applied based on

importance and magnitude of project.

3. Consistent development and review of useful and relevant Guidelines, Specifications and

Design Manuals that consider socio-environmental changes and other dynamics.

4. Advances in Value Engineering technologies, designs and methods of implementing

infrastructure projects.

5. Determination of up to date information on demographic distribution, statistics and prevalent

environmental factors for the development of suitable and appropriate policies for effective

implementation of infrastructure projects.

C. Linking Research and Infrastructure Development

Infrastructure development is the basis of better life as well as the nerve centre and key to the

achievement of any visionary and pragmatic/sustainable socio-economic growth of a country in any

modern society.

On the other hand, infrastructure is time dependant in terms of design life, relevance and

performance.

The contemporary Civil Engineer, for example, is increasingly faced with major tasks and challenges

as a consequence of increased socio-economic activities prompted mainly by population explosion




and changing lifestyles. Such tasks and challenges necessitate the construction of larger civil

engineering structures such as high rise buildings for increased accommodation, large storage

facilities such as liquid tanks as well as highways and bridges that can cater for heavier loads and

higher capacity of transportation due to increased traffic. On the other hand, the recently

developed environmental policies intended to control degradation can be imposing.

Furthermore, the Civil Engineer in developing countries is constrained by lack of sufficient or

necessary financial resources and technical capability. Under these circumstances therefore, the

Civil Engineer has to constantly develop innovative engineering concepts and methods to face and

resolve such challenges in a most appropriate manner. For developing countries in particular, the

methods must take into account factors such as appropriate technology, investment benefit in terms

of time, cost reduction of maintenance requirements and most of all, reasonable sustainability.

The foregoing facts necessitate advanced research geared towards enhancing infrastructure

development.

Fundamentally, as shown in Figure 1, Research and Infrastructure Development are symbiotically

linked/related.




Fig. 1: Symbiotic link/relation between Research and Infrastructure Development and their role

and contribution to Sustainable Socio-economic Development

D. Some benefits of Research Based Infrastructure Development

In order to optimally reap the benefits of any form of infrastructure the adoption of relevant

technologies developed on the basis of proper research is a prerequisite.

Some of the main benefits of research based infrastructure development include: -

1. Achievement of appropriate designs tailored for a particular environment and prevailing

conditions.

2. Achievement of Value Engineering structures which ensure reduction in cost and enhancement

in structural performance.




3. Avoidance of development of unnecessary and/or archaic infrastructure based on outdated

methods of design and construction, which turn out to be a menace and burden on the

taxpayer.

4. Guaranteed determination of effective use of natural and financial resources for the

achievement of extensive infrastructure development through urban to rural areas.

E. Some case examples of Research Based Infrastructure Development

1. International

Japan is usually cited as a typical example of one of the countries that advanced its research based

infrastructure development to achieve one of the most rapid post World War II technological and

economic growths.

Some of the milestone structures in which the Proponent Researcher was part of the Research Team

include:

a) The 4km long (the Worlds largest 2km centre to centre span) Akashi Kaikyo Suspension Bridge.

b) The 15.1km Tokyo Bay Highway consisting of bridges and undersea tunnels connecting

Kawasaki and Kisarazu man-made islands.

c) The Kansai International Airport constructed on a man-made island.

d) The futuristic city of Minato Mirai 21 (MM21) in Yokohama.

2. Regional

Research based designs and methods of construction have been developed and applied for

infrastructure development in our East and Central Africa Region realizing cost savings of between

30~50%, whilst ensuring enhanced structural performance. Some of the projects include:-

a) The approximately 240km Addis Ababa ~ Debre markos International Trunk Road in Ethiopia

traversing to Sudan and branching towards Eriteria.

b) The Songwe International Airport in Tanzania.

c) The Isiolo Airport in Eastern Kenya.

d) Access roads, pad foundations for oil drilling rigs and airstrips for oil exploration in Jonglei

State, Southern Sudan.

F. Proposed vital policy for advancing Research Based Infrastructure Development

In order to foster advances in research that would contribute immensely to the enhanced

development of infrastructure, it is imperative to develop policies for Value Engineering whereby the

accruing benefits or acquisition savings can be shared by practically all stake holders.




The successful application of the VE process can contribute measurable benefits to the quality of the

surface transportation improvement projects and to the effective delivery of the overall

infrastructure development programs.

The Federal Highway Administration of the United States for example, has VE programs designed to:

encourage the pragmatic, enhanced and consistent application of VE approach

assure the projects required by law and regulation receive VE analysis

encompass a variety of VE activities focused on technical assistance, liaison with industry, promotional activities, and active participation in studies, and

focus on education and training of public institution employees and Stakeholders through the presentation of VE workshops.

In the United States, VE is incorporated as a matter of policy in the Federal Aid Program where it has

been applied both within the Federal Government and the transportation industry. The Federal-aid

Act of the 1970 required VE and cost reduction analyses on Federal-aid projects.

1.5 Mode of Pragmatic Achievement of Goals and Objectives

As a fundamental research definitive approach and orientation, the research in infrastructure

should basically constitute of the following.

1. Constituting competent and reliable Professional Research Committees that can

effectively and efficiently realize the National Infrastructure Development Vision and

Mission in line with the Vision 2030.

2. Fostering Qualitative Research as outlined in this Proposal.

3. Undertaking comprehensive review of existing literature, State of the Art research and

technologies.

4. Determining research findings and technologies that can be adopted immediately

and/or modified to provide appropriate cost and time-effective solutions to National

development needs.

5. Undertaking basic research that can provide general technical guidelines for such vital

data and information as introduced in this Proposal regarding soils mapping,

environment factors, development activities and basic study components.

6. Adopting, incoporating and/or developing unique R&D Models that are tailored to our

local needs, environment, technical problems, available resources and engineering

capacity.

7. Emphasizing the recognition the importance of research at all main stages of Project

11 Chapter 2Appreciation, Interpretation and Justification of Submission Requirements | Kensetsu Kaihatsu Limited

Chapter 2 Appreciation, Interpretation and Justification of Submission

Requirements

2.1 Main Solicitation Requirements

The Proponent Researcher appreciates the fact that the NCST is soliciting for ideas and priority areas of research which would contribute to the acceleration of national development particularly in line with the Kenya Vision 2030 upon which the foundation is Science, Technology & Innovation (ST&I). In response, the Proponent Researcher wishes to refer to Chapter 3 in particular and this Proposal in general.

2.2 Fundamental Recognition

It is hereby interpreted that Science, Technology & Innovation (ST&I) as the key foundation whose integration could raise productivity and efficiency across all sectors of the economy.

The importance of enhanced physical infrastructure in this regard is certainly a fact that is well appreciated in any part of the world that appreciates a knowledge-based economy and has been

practically demonstrated in countries such as Japan, which is usually cited as a typical example of one of the countries that has made the most rapid technological and economic growth and development in the post World War II era. Their research oriented approach in the development of infrastructure has made Japanese technology become the focus and model for not only the Asian Tigers and developing countries but also of the first world.

2.3 Statement of Invitation and Overall Objective

2.3.1 Invited Stakeholders

It is interpreted that the Stakeholders invited to submit research priority areas are policy makers, scientists, researchers and civil society. The Proponent is a researcher/scientist who specializes mainly in the fields of civil & geotechnical engineering, soil mechanics, materials science, geosciences, geomathematics, and applied geophysics (Refer to the publications listed in the curriculum vitae). 2.3.2 Overall objective

It is inferred that the overall objective is to solicit for ideas and research priority areas for funding.




The Proponent Researcher proposes the enhancement of research for effective achievement of rapid infrastructure development as a means of ensuring an integral part of the Vision 2030.

2.4 Interpretation of NCST’s Mandate NCST’s mandate is derivatively interpreted as follows.

1. Advice the government of Kenya on policies and matters relating to scientific and technological activities and research required for socio-economic development.

2. Promote and coordinate scientific and technological research needed to accelerate national development in line with Vision 2030.

In this regard, Eng. Stephen Kogi, Chief Engineer, Materials Testing & Research Department of the Ministry of Roads and the Proponent Researcher proposed, at the 15th African Regional Conference on Soil Mechanics and Geotechnical Engineering (15th ARC SMGE) held in July 2011 in Maputo, Mozambique, the establishment of a Three-Tier System Model involving the Public Sector, Academic Sector and the Private Sector for the purposes of achieving an effective coordination programme for research and development activities.

2.5 Main Target of National Research and Development Agenda (NRDA)

It is considered that the main target of the NRDA is to prioritize, promote and harness research and innovation so as to provide research based solutions in support of the knowledge-based economy. In this regard, reference can be made to Chapter 3 in particular and this Proposal in general whereby it can be clearly noted that significant advances have been made in developing appropriate, suitable and economically viable research based solutions. However, these technologies and research findings are yet to be harnessed and promoted accordingly.

2.6 Interpretation of NCST’s Main Obligation in Response to the NRDA’s Requirements It is interpreted that NCST’s main obligation in response to the NRDA requirements is to ensure that the NRDA is in line with the flagship projects identified in the Kenya Vision 2030, Millennium Development Goals (MDGs) and in conformity with the constitution of Kenya. Kensetsu Kaihatsu Limited, with the Proponent Researcher as the Team Leader and Lead Research Consultant, undertook comprehensive Research as well as Basic and Detailed Design Studies subsequent to which they developed a unique research based design for the Isiolo Airport (one of the flagship projects identified in the Kenya Vision 2030), incorporating some of their Value Engineering technologies (Ref. to Section 3.6 of Chapter 3 of this Proposal). The developed unique designs, methods of construction and quality control techniques, which were implemented by the Kenya Airports Authority, realized a total cost savings of 62% and a structural enhancement of 1.8 times in comparison to the conventional designs. The construction was initiated in March 2011 and is due for completion in May 2012 (this year). This is one of the major examples of the benefits of prioritizing and enhancing research in physical infrastructure.




2.7 Main Objectives of the NRDA

2.7.1 Advisory Services

14 Chapter 3Brief Introduction and Discussions of Proposed Research Priority Areas in Relation to Physical Infrastructure Development within the Kenya Vision 2030 Development | Kensetsu Kaihatsu Limited

Chapter 3 Brief Introduction and Discussions of Proposed Research Priority

Areas in Relation to Physical Infrastructure Development within the Kenya

Vision 2030 Development

3.1 Preamble on Fundamental Importance

The preamble on the fundamental importance of enhancing research in physical infrastructure as a priority area is introduced in Chapter 1.

3.2 Employment of the SAC in Establishing a Viable and Efficient ST&I Matrix for Sustainable

National Infrastructure Development Plan

It is important to establish a viable and efficient science, technology and innovation matrix for purposes of developing a most optimum and appropriate research regimme for an advanced national infrastructure development plan. In so doing, the Systematic Approach Concept, which was first proposed by the Proponent Researcher, is considered necessary.

3.3 Necessity for the Enhancement of Research in Value Engineering (VE) Technologies

3.3.1 Fundamental definition of VE

Basically, Value Engineering (VE) is defined as a systematic process of review and analysis of a

project, during the concept and design phases, by a multidiscipline team of persons not involved in

the project that is conducted to provide recommendations for:

(a) Providing the needed functions safely, reliably, efficiently, and at the lowest overall cost, (b) Improving the value and quality of the project, and (c) Reducing the time to complete the project.

3.3.2 Contribution (Role) of VE technologies in the achievement of Integrated Development (ID)

The concept of Integrated Development was first introduced by Mukabi in 1998. It fundamentally entails that:

1. Every infrastructure project should be required to undertake research during the design and/or construction stages in order to develop VE technologies that will ensure cost and time savings.

2. That part of the acquisition cost savings (refer to sub-section 3.3.4) that accrue from the effective development and employment of the VE technologies be utilized for social welfare and economic empowerment of the local population through which, for example, the road traverses.

3. This should specifically aim at increasing employment, reducing poverty and enhancing education and healthcare through the provision of the necessary and sustainable physical




facilities such as schools, health centres, cottage industries, small enterprise agro-factories, leather tanning center as well as human and other resources.

3.3.3 Role of VE Technologies in socio-economic development

If well developed and administered, VE technologies can realize enormous cost savings whilst enhancing the structural performance of the civil, geotechnical or building structures. Under normal circumstances, and as explained in the foregoing sub-section 3.3.2 and demonstrated in the subsequent sub-section 3.3.4, these savings can be effectively utilized to realize enhanced socio-economic development.

3.3.4 Some Policy and Contractual Aspects of VE

1. Some Relevant Policies on Value Engineering Based on International Practice

(a) As required by Section 36 of the Office of Federal Procurement Policy Act (41 U.S.C. 401), agencies shall establish and maintain cost-effective value engineering procedures and processes. Agencies shall provide contractors a substantial financial incentive to develop and submit Value Engineering Change Proposals (VECP). Contracting activities will include value engineering provisions in appropriate supply, service, architect-engineer and construction contracts as prescribed by 48.201 and 48.202 except where exemptions are granted on a case-by-case basis, or for specific contracts, by the agency head.

(b) Agencies shall:- (1) Establish guidelines for processing VECP’s, (2) Process VECP’s objectively and expeditiously, and (3) Provide contractors a fair share of the savings on accepted VECP’s.

(c) Agencies shall consider requiring incorporation of value engineering clauses in appropriate subcontracts

(d) (1) Agencies other than the Department of Defense shall use value engineering program requirement clause (52.248-1) in initial production contracts for major system programs (see definition of major system in 34.001) and for contracts for major systems research and development except where the contracting officer determines and documents the file to reflect that such use is not appropriate. (2) In Department of Defense contracts, the VE program requirement clause (52.246-1, Alternatives I or II) in initial solicitations and contracts for major system acquisition programs shall apply.

(e) Value engineering incentive payments do not constitute profit or fee within limitations imposed by 10 U.S.C. 2306(d) and 41 U.S.C. 254(b) {see 15.404-4(c)(4)(i)}

(f) Generally, profit or fee on the instant contact should not be adjusted downward as a result of acceptance of a VECP. Profit or fee shall be excluded when calculating instant or future contract savings.

(g) The contracting officer determines the sharing periods and sharing rates on a case-by-case basis using the guidelines in 48.104-1 and 48.104-2, respectively. In establishing a sharing period and sharing rate, the contracting officer must consider the following, as appropriate, and must insert supporting rationale in the contract file: (1) Extent of the change. (2) Complexity of the change




(3) Development risk (e.g., contractor’s financial risk). (4) Development cost. (5) Performance and/or reliability impact. (6) Production period remaining at the time of VECP acceptance. (7) Number of units affected.

(h) Contracts for architect-engineer services must require a mandatory value engineering program to reduce total ownership cost in accordance with 48.101(b)(2).

(i) Agencies shall establish procedures for funding and payment of the contractor’s share of collateral savings and future contract savings.

(j) 2. Contractual Aspects of value Engineering Based on International Practice

a) Contractual Definition

In accordance with subpart 48.101 of the Federal Acquisition Regulation (FAR), Value Engineering is the formal technique by which consultants/contractors may (1) voluntarily suggest methods for performing more economically and share in any resulting savings or (2) be required to establish a program to identify and submit to the Government methods for performing more economically. Value engineering attempts to eliminate, without impairing essential functions or characteristics, anything that increases acquisition, operation, or support costs.

b) Conceptual Proposal Under normal procedural circumstances of submitting a Value Engineering Change Proposal (VECP), the Conceptual Proposal (CP) is intended to expedite the initial review of a VECP idea, as well as minimize the Contractor’s initial capital investment and risk in developing the VECP. This procedure allows the Contractor to submit a conceptual plan, and only requires the Department (Agency) to assess the general merits and technical feasibility of the CP. The contractual requirements, detailed reviews, and cost analysis at this juncture should receive a lower level of scrutiny, compared to the level of review if the conceptual VECP is approved and a formal proposal is necessary.

c) Value Engineering During Design In his MSc. Thesis on “Value Engineering – An Opportunity for Consulting Engineers to Redefine Their Role”, Peter O’Farrell emphasizes the need for Consultants to incorporate Value Engineering (VE) principles, concepts and ideologies during the design stage. He demonstrates the fact that poor designs and documentation can be responsible for substantial increase in project costs and poor performance of the structures culminating in high maintenance costs. On the other hand, in the United States Environmental Protection Agency Circular of November 2005 on Value Engineering (VE), it is stated that the VE study is different from routine design studies or reviews. The design reviews, for example, concentrate on functional aspects, such as whether the design works, is sufficiently reliable, and meets the designer’s contractual obligations. VE, on the other hand, is focused on reducing investment necessary to achieve those functions. It should be noted that the focus of VE does not preclude the VE team from identifying technical errors or omissions and alerting the designer so that these problems can be taken into consideration during the design reviews.




The VE study should be scheduled so as to minimize the impact on the design schedule.

d) VECP Submittal and Review Procedures The VECP submittal and review procedures are discussed under subpart 104-10 – VALUE ENGINEERING CHANGE PROPOSAL of the Standard Specifications for the Construction of Roads and Bridges on Federal Highway Projects.

e) Processing VECP’s Processing of the VECP’s is outlined under subpart 48.101 of the Federal Acquisition Regulation (FAR).

f) Construction Inspection Guidance for VE Projects The Construction Inspection Guidance for VE Projects subpart 104.13 of the Standard Specifications for the Construction of Roads and Bridges on Federal Highway Projects.

g) Mode of Sharing Net Acquisition Savings

Subpart 48.101 of the Federal Acquisition Regulation (FAR) provides the details on sharing

arrangements including:

1. – 48.104-1 Determining sharing period 2. – 48.104-2 Sharing acquisition savings 3. – 48.104-3 Sharing collateral savings 4. – 48.104-4 Sharing alternative-no-cost settlement method 5. – 48.104-5 relationship to other incentives

Under subpart 48.104-2 (a) on supply and service contracts, the following stipulations are made.

(1) The sharing base acquisition is the number of affected end items on contracts of the contracting office accepting the VECP. The sharing rates {Government/Consultant(Contractor)} for net acquisition savings for supplies and services are based on the type of contract, the value engineering clause or alternate used, and the type of savings, as tabulated in Table 3.1 below.

(2) Acquisition savings may be realized on the instant, concurrent contracts, and future contracts. The Consultant/Contractor is entitled to a percentage share {see paragraph (a)(1)} of any net acquisition savings. This may occur on the instant contract or it may not occur until reductions have negotiated on concurrent contracts or until future contract savings are calculated, either through lump-sum payment or as each future contract is awarded.

3. Some Examples of Value Engineering Applications in East and Central Africa

The concepts of Value Engineering have been adopted in developing Value Engineering Designs and

Technologies that have been successfully applied in some countries in this Region, and culminated in

the realization of Acquisition Savings of between 30 and 60% depending on the nature, level,

complexity, environmental and resource factors, among others.

This has been realized in Ethiopia, South Sudan, Tanzania and Burundi through the following modes

of approach.

1. The Project Consultant recommends and submits to the Financier/Employer (Client), a Value Engineering Change Proposal (VECP).

2. The Financier/Employer (Client) engages an independent in-house Consultant to evaluate and review the original design with the objective of adopting the VECP.

3. The Project Contractor engages the services of an independent in-house Consultant to evaluate and review the original design with the objective of developing a VECP and submitting it to the Employer (Client) for approval.

4. The Employer (Client)/ Project Contractor mutually agree to engage the services of an independent Consultant to evaluate and review the original design with the objective of adopting the VECP.

It is important to note that in most cases, the acquisition savings would not only be realized on the

instant contract but also substantially on the maintenance cost savings.

However, in such cases, the initial sharing should only consider the acquisition savings of the instant

contract and an arrangement agreed upon regarding future savings resulting from low maintenance

requirement ratios.




4. Some Recommendations

The following basic recommendations are considered vital.

(1) Agencies be encouraged to adopt Value Engineering (VE) concepts, principles and approach.

(2) Value Engineering Policies be adopted and promoted accordingly. (3) Agencies make it a prerequisite that Design Reviews be based on a Value

Engineering approach which introduces VE technologies, methods of design and construction.

(4) It would be a major incentive for Consultants and Contractors if the employing Agencies would consider the maintenance cost savings as future acquisition savings computed on real time basis and paid in mutually agreed percentages in the future after practically realizing such savings.

3.4 Examples of VE Technologies Developed and Applied in East Central Africa Region

3.4.1 Brief conceptual background

In their natural state, most geomaterials are usually deficient in one or more of the particle fractions required. Consequently, mechanical stabilization plays an important role in achieving a pavement structure which, under loading conditions, is appreciably resistant to shear and deformation. In developing the Optimum Batching Ratio Method (OBRM), Mukabi (2001) considered that; such geomaterials would have a particle size distribution that tends towards a correctly proportioned ratio that would yield optimum density and adequate strength to resist stress-induced deformation.

(1) Optimum Batching Ratio Method (OBRM)

The OBRM is a mechanical stabilization method that was odeveloped on geo-scientific basis. Based on this method, the blending of two otherwise structurally inferior geomaterials with different characteristics can be achieved at optimum proportionate levels thereby enhancing the vital geotechnical engineering properties such as mechanical stability, bearing capacity, strength and deformation resistance. (2) Optimum Mechanical and Chemical Stabilization (OPMCS)

OPMC is the combination of optimum mechanical batching (OBRM) and optimum chemical mixing of, and into geomaterials with varying properties. These methods have been practically applied for the design and construction of various civil engineering projects in East and Central Africa and have been proven to: 1) promote cost-effective use of otherwise relatively inferior geomaterials, whilst ensuring the achievement of sound geotechnical engineering structures; 2) contribute immensely to environmental




conservation through the reduction in use of borrow and/or extruded geomaterials; 3) provide partial solutions to problematic soils, and; 4) realize significant reduction in the requirements of chemical stabilizers.

Case Study Analysis of OPMC Improved Foundation Ground, Pavement and

Other Geo-structures Employing the GECPRO Model

J.N. Mukabi, Kensetsu Kaihatsu Limited, Kenya, [email protected]

ABSTRACT

The degree of effective improvement of the OPMCS (Optimum Mechanical and Chemical Stabilization) technique in enhancing the vital geotechnical engineering properties of ground and geomaterials is illustrated through some typical results based on laboratory and in-situ experimental testing performed on various geomaterials within the East and Central African region. A case example of the most recent application of the OPMC technology in realizing Value Engineering (VE) design and construction of a runway pavement for the Isiolo International Airport in the Eastern State of Kenya is also provided, whilst case study analyses are carried out for

a road pavement structure in Juba, a pad foundation in the Jonglei Flood Plains of Southern Sudan and a retaining wall along a steep slope in Addis Ababa, Ethiopia. The results from this Study demonstrate that the degree of improvement of the consolidation properties, bearing capacity, shear strength and Young’s modulus (elastic stiffness) are mainly a function of the quantitative and qualitative level of OPMCS.

1. INTRODUCTION

1.1 Brief Background of OPMCS R&D

Fulfillment of specifications within acceptable construction practices requires high-quality

geomaterials which are usually expensive and mostly involve long haulage distances of such

materials thereby increasing the period of construction and, most of all, the project cost. On

the other hand, the use of “substandard” geomaterials, which, in singularity, are mostly

deficient in mechanical stability and other geo-properties, certainly requires the application

of innovatively researched ground and material improvement techniques.



25 1. INTRODUCTION | Kensetsu Kaihatsu Limited

The OPMCS is an extrapolation of the OBRM (Optimum Batching Ratio Method), which was

developed during the prevalence of the late 1997 to early 1998 El-Nino floods causing

detrimental damage to pavement structures and bridge foundations along the 330km Tana

Basin Project Road that was under construction in the Coast/North-Eastern States of Kenya

during this occurence .

OBRM is fundamentally based on the theory that regards soil as an assembly of particles

whose integrated motion can be characterized theoretically by basic concepts and

fundamental principles of continuum mechanics and models that consider probabilistic

perspectives of microscopic state and multi-dimensional analysis (Mukabi, 2001a [1]). The

application of this technology was first reported by Mukabi and Shimizu, 2001b [2] and

Mukabi et al (2001c) [3]. OPMCS was later developed during the construction of the 240km

Addis Ababa ~ Debre Markos international trunk road connecting Ethiopia to Sudan in the

West and Eriteria in the East.

1.2 OPMCS – Cost Aspect and Maintenance requirement Ratios

Through the application of the OPMCS technology, most road projects have realized cost

savings of 30 ~ 40% and reduction of maintenance requirement of up to 60% for pavement

layers and composite structures (Kogi et al, 2011 [4]).

1.3 OPMCS as an Environmental Mitigation Measure

Mukabi et al, 2007b [5] and Kogi et al, 2011 [4] have reported achievement of the following

through the application of the OBRM and OPMCS technologies: 1) reduction of volume of

materials used by approximately 40% in most cases; 2) less disturbance of land for borrow

pits; 3) reduced amounts of disposable soil during construction; 4) reduced risk of collapse of

geo-engineering structures and; 5) environmentally friendly due to; utilization, as much as

possible, of locally available material and reduction of dust, distances (lengths of access

roads) to borrow pits, geomaterial quantities required and land acquisition, among other

factors. Whilst developing these methods, comprehensive appraisals and environmental

assessments that would lead to sustainable development with minimal negative

environmental impacts, were undertaken [5].

The example depicted in Figure 1 was part of the design for Wau~Abyei Trunk road

constructed in the northern oil fields of the Republic of Southern Sudan.

A summary of the approach, considerations and contribution of OBRM and OPMCS from an

environmental and geotechnical engineering perspective are discussed in [5].




2. RECENT APPLICATION OF OPMCS TECHNOLOGY – RUNWAY PAVEMENTS

The most recent application of the OPMCS is manifested in the design and on-going

construction of the runway pavements, taxi way, aprons and parking bays of the Isiolo

International Airport located in the Eastern State of Kenya.

Figure 2 is a typical depiction of some of the basic results realized from laboratory

experimental testing, whilst Figures 3 and 4 show the plan and one of the typical cross-

Figure 2 : Enhanced strength as a result of particle agglomeration for varying modes of stabilization

It can be noted from this figure that: a) the UCS is significantly enhanced as the soil

particles agglomerate progressively with time particularly for the cemented geomaterial; b)

soil particle agglomeration is dependent on the mode of stabilization; c) the effects of

geogrid reinforcement are more noticeable with increased agglomeration possibly due to the

influence of confinement in increasing the degree of interlocking of particles culminating in

reduction of voids ratio, and d) the degree of soil particle agglomeration is higher under

OPMC stabilization in comparison to geogrid reinforcement thus confirming the theory that,

in comparison to other influencing factors, cementation processes have greater impact on

agglomeration mechanisms.

29 3. BRIEF INTRODUCTION OF THE GECPROM – GEOMATHEMATICO-EMPIRICAL MODEL | Kensetsu Kaihatsu Limited

The site location of this project is predominated by Black Cotton Soils (BCSs), which are

highly problematic and expansive in nature. Consequently, as can be observed from Figure 4,

Ground Improvement (GI) was undertaken by adopting the Moisture Control Sand Column

(MCSC) method proposed by Mukabi et al, 2010b [6]. Both laboratory and field experimental

testing results indicate that, on the average, this method typically enhances the bearing

capacity, strength and deformation resistance of BCS subgrades by more than five - fold

(Kensetsu Kaihatsu, 2011 [7]) .

The uniqueness of this design includes the: 1) combination of OPMCS and geosynthetics; 2)

use of geotextile as a separation, filtration and stress mobilization interface; 3) use of

geogrid as a reinforcement and tensile stress control component, and 4) realization of high

composite structural enhancement factor.

3. BRIEF INTRODUCTION OF THE GECPROM – GEOMATHEMATICO-EMPIRICAL MODEL

3.1 Preamble

An appreciably versatile mechanistic-empirical geo-mathematical model (GECPROM)

encompassing most of the concepts developed in this Study as well as other related studies,

is proposed. GECPROM is designed to probe and estimate changes in vital seismic geo-

properties for clayey geomaterials and ground. The significant advantage of this model is

that various geotechnical changes and geostructural behavior can be modeled from a single

sophisticated experimental test, whilst simultaneously catering for the effects of drainage

conditions, loading rate, and consolidation stress-strain-time history. The complete and

perfect model would, categorically, have to be multidimensional with relativistic coaxiality,

relations and consequences. The GECPROM is primarily designed to be adopted at the study

or investigative stage facilitating basic data and information that can then be applied for

design of foundations, pavements and other geostructures and/or comprehensive

experimental testing and research regimes, input for global and constitutive models,

counter/cross-checking and designating the confidence levels of laboratory and field

experimental testing, construction control, risk analysis and technical mitigation measures in

seismic zones besides the integral role of prediction of ground response and retrospective

behavior.

This model is to be further developed to incorporate the Consolidation and Shear Stress

Ratio (CSSR) and Modified Critical State Theory (MCST) modules (Mukabi and Hossain, 2011e

[8] and Mukabi, 2011d [9]), in order to effectively complement the ESDAM (Environmental,

Strength and Deformation Analysis Model), which is under development based on some of the

concepts developed in the process defined in the sedimentary model that merges the

Simsafadim-Clastic and Discrete Element model.




3.2 Probing and prediction of shear and elastic moduli

The fundamental equation for the shear modulus developed from CSSR model functions is

expressed as:

(1)

where is the initial shear modulus at a variable stress point , =

is the

arbitrary or designated consolidation stress ratio traced to ,

is the initial shear

modulus determined at in-situ overburden pressure, =0.95 and

=0.35 are geomaterial

experimental constants, the values of which are applicable for most natural stiff to hard clayey geomaterials, while =1.16 and =0.4 for stress states in the 1st quadrant and =-1 for stress states in the 4th quadrant accordingly [8].

In developing the model functions it is important to consider the relativistic rates of change

of at least within the 1st quadrant of the { , q} stress plane for stress ratio and

orientation whereby, = and = and the total derivative is expressed in a

generalized form as:

(2)

(3)

3.3 Geo-mathematical determination of Initial Yield Strain (IYS) for varying conditions

GECPROM retrospectively reflects and mirrors the conditions applied during the testing at

stress point . Unlike the initial shear and elastic moduli which can be ideally considered to

be only stress state dependent, the Initial Yield Strain {(εa)ELS(YI)} representing the threshold

of the initial sub-yield surface, , which is dependent on various factors such as

consolidation stress-strain-time history, shear strain rate, drainage conditions and OCR [1],

is rather complicated in terms of modeling it in singularity. In the generalized state

therefore, the is expressed as a function of multi-variables in the form;




(4)

where, is the current stress state, represents the consolidation stress-strain

history, is the secondary consolidation time (ageing), is the

overconsolidation ratio factor, defines the drainage conditions and is the strain rate

effect. However, corroborative deduction made from [8] and [9] indicates that the variables

can essentially be simplified as:

The generalized analytical function of the resulting

expressed in compound terms is:

(5)

3.3.1 Stress States ( ) and Bounding Limits (BL)

The basic generalized equation defining the impact of stress states is expressed as:

(6)

where, constants

=0.98,

=0.32, =0.4, for stress states in the 1st quadrant and, =-1,

in the 4th quadrant, while =1.16 [8].

Carrying out 2nd order partial differentiation w.r.t we obtain,

(7)

Performing the same w.r.t we obtain,

3.3.2 Consolidation Stress-strain history ( )

(9)

where

=1.9×10-3 is a constant, is the secondary consolidation factor, is the

overconsolidation factor and

is the initial yield strain determined under normally

consolidated conditions at a standard time period designated after the end of primary

consolidation.

(10)

where ,

are the effective axial and radial stresses respectively determined at the

threshold of

is the stress ratio during consolidation, =-1, =+1

be determined as;

(11)

where , are the initial drained and undrained elastic moduli respectively.

3.3.4 Cyclic prestraining ( )

(12)




3.3.5 Strain rate

(13)

where the subscripts SR denote Strain Rate, ASR: Applied Strain Rate during testing or

arbitrarily designated and RSR: Reference Strain Rate.

3.4 Deriving shear strength from elastic stiffness and generation of secant modulus prediction curves

Developing an appreciably reliable correlation between shear strength at failure and the elastic (Initial) stiffness is important in determining a more precise parameter (qmax) closely related to a ground property (E0). The GECPROM module for this relation is:

(14)

Figures 6 (a) and (b) depict the experimental and modeled characteristic curves for stress ~ strain behavior and the decay of stiffness plotted as a function of strain level for intact and reconstituted specimens sampled and tested in Japan adopting sophisticated Triaxial testing equipment.

For generating the prediction curves that characterize the secant and initial moduli, ,

Eqs. (15) and (16) are applied respectively, in conjunction with other equations proposed by

[8].

Figures 5 (a) and 5 (b) compare experimental test results of stiff pleistocene clays sampled and tested in Japan. In these figures all the curves modeled by the GECPROM show a very good agreement in comparison to the experimental trends. It can also be inferred that the curves for the reconstituted specimens deviate significantly from those of the intact ones in all cases.

4.2 Juba River Port Access Road – Road Pavement Structure

The Juba River Port Access Road traverses areas that are predominantly overlain with high

problematic and expansive Black Cotton Soils (BCS) within swampy stretches. During the

implementation of an Emergency Project grant aid funded by the Japan International

Cooperation Agency (Government of Japan), it was necessary to adopt cost-effective

methods of improving the existing ground for purposes of reducing the quantities that would

be required for the upper pavement layers (subbase and base courses) mainly due to lack of

suitable road construction materials within reasonable haulage distances. Full-fledged field

experimental sections with three varying pavement structural configurations were designed,

as shown in Figures 6 ~ 8, and implemented under otherwise similar environmental

conditions for purposes of determining the most optimum and cost-time-effective VE design,

appropriate methods of construction and reduction in the Maintenance Requirement Ratio

[4]and [10].

4.3 In-situ Modeling of Response of Varying Pavement Structural Configurations

Monitoring, laboratory testing of samples hand-curved and/or cored from the experimental

trial sections and in-situ measurements were udertaken consistently for a period of 3 years

(1092 days) as can be noted from Figure 9 (a), which depicts the effect of particle

agglomeration on shear strength development characteristics mainly as a result of

cementation and secondary consolidation due to heavy dynamic traffic loading. A high rate

of progressive strength development can be observed in the initial phase.

Figure 9 (b) shows the quantitative variation of the elastic stiffness with layer quality,

configuration and depth for the three different types of trial sections. The results reported

were measured on the 1092nd day, while the behavior of the varying pavement structures

was modeled by using the GECPROM [8].

4.4 Oil exploration project in Jonglei Flood Plains in Southern Sudan

The scope of the project included the design and construction of pad foundations, access

roads, airstrips and base camps foundations. The design criteria took into consideration

various environmental and load factors; including dead loads, live loads, static and dynamic

loading effects during drilling operations and construction equipment. Some representative

results from the design studies, which portray dependency of stress-strain characteristics on

the mode of stabilization as well as type and location of geosynthetics reinforcement, are

depicted in Figure 10, while a typical design cross section is shown in Figure 11.

4.5 Addis Ababa ~ Debre Markos International Trunk Road – Retaining Wall

During a road and bridges rehabilitation programme under Grant Aid funding by the

Government of Japan, slope failure occurred at a stretch around Sta. 9+310km from the city

centre of Addis Ababa along the Addis Ababa~Goha Tsion~Debre Markos International Trunk

road traversing through the Blue Nile, and which forms an integral part of the all-important

north-western corridor connecting to the western part of The Sudan, whilst branching off to

the east towards Gonder to the Eriterian border.

As a result, longitudinal cracks were prevalent within the asphalt concrete and significant

shear failure occurred right through the pavement structure and subgrade. Due to

environmental and financial constraints, it became imperative that a cost-effective method

utilizing locally available material as much as possible, be employed. OPMCS technology was

employed in improving the available geomaterials and existing subgrade. Typical

experimental test results and design cross section are shown in Figures 12 and 13

respectively. Enhanced performance in terms of deformation resistance can be observed in

Figure 12.

4.2 Study Objectives and Approach

4.2.1 Basic analysis

The objectives of the Study are stipulated under Item 2 of Section 5 of this RFP, which address the Terms of Reference (TOR).

The Study objectives are:-

(iii) Development of design procedures, construction specifications and quality control systems for Geosynthetics reinforced embankments and pavements.

(iv) Performance evaluation of RE walls constructed under Nairobi - Thika Project and design of monitoring programmes.

Essentially, according to the Consultant’s interpretation, the RFP requires the design of a research regime that is primarily aimed at developing construction and performance Specifications for Geosynthetics reinforced Geomaterials for road embankments and pavement structures in particular, including design procedures and quality control systems as well as evaluation regimes and procedures for evaluating the performance of existing geo-structures and retaining walls.

From a global perspective the methods of design, construction, quality control systems and performance specifications should ensure that the procedures and techniques are pragmatically applicable and;

6. Cost and time effective predominated with a Value Engineering (VE) component. 7. State of the Art so that they are applicable to inclusion in the Road Design Manual (K) and

Standard Specifications. 8. Are particularly tailored for tropical environmental conditions within the East and Central

Africa Region. 9. Satisfactorily innovative enough to provide a useful basis for developing alternative and more

effective stabilization techniques for Geomaterials, new engineering products, more cost-effective concepts, methods of design and construction techniques which are also environmentally friendly.

10. Provide engineering indicators for quality control, monitoring and evaluation of performance of Geostructures.

4.2.2 Brief background of Necessity of Consultancy Services

Comprehensive testing to determine the physical and mechanical index properties of Geogrids such as isotropic stiffness ratio, junction efficiency, radial stiffness (secant modulus), response to various chemicals, temperature effects, torsional rigidity, load transfer capability, and aperture stability modulus have been undertaken. Numerous Case Study Analyses have also been carried out yielding impressive results for a few well manufactured reinforcement Geogrids.

Nevertheless, experimentally based scientific and engineering theories, concepts and principles that delineate the soil particle–Geogrid interaction that would enable the stipulation of a pragmatic Performance Based Specification have yet to be clearly established. As a consequence, it is difficult for the Design Engineer to quantitatively determine the actual contribution and performance of the Geogrid, in terms of initial engineering parameters, within the composite pavement structure. This makes it impossible for the Design Engineer, Employer/Client and




Contractor to compute the actual cost-savings that can be realized as a result of using Geogrids in comparison to other methods of soil improvement/stabilization. Furthermore, hardly any research has been undertaken to establish the progressive interlock mechanism with the increase in degree of compaction/consolidation in relation to the physical nature and configuration of the Geogrid for various Geomaterials.

4.4 Overall Technical Approach

The overriding principle of the overall technical approach is to initially establish the appropriate, most effective and optimum methodology to achieve the objectives of the Study based on research oriented scientific and engineering perspectives. Subsequently, the established methodologies are to be managed and administered in a cost-time effective manner. The individual tasks that would provide solutions to the problems associated with the assignment are to be comprehensively analyzed within the framework of the scope of the Study stipulated in the TOR and the critical tasks distinctly identified as demonstrated in Section 5.3 of Chapter 5 of this Technical Proposal. Once the critical tasks are analyzed, effective measures of implementation are presented within the Work Plan.

Consistent and comprehensive monitoring, evaluation, assessment and auditing of the progress, technical, administrative and logistical problems, and bottlenecks that affect efficient and cost-effective delivery of the assignment is to be undertaken. The methodologies and work plan take into account the organization structure, proposed staff and their capacity to expedite the assignment as shown in Chapter 6 of this Technical Proposal. The approach and methodology to achieve efficient delivery of services required is discussed extensively under Section 4.6.

4.5 Overall Methodology

Any engineering exercise involving the development of approximately applicable specifications requires that comprehensive research and testing be undertaken. In this case, the RFP is for Consultancy Services for:

1. Studies on Geosynthetically Reinforced materials for Road Embankments and Pavements; and,

2. Performance Evaluation of Reinforced Earth [Geo-structures and Retaining] Walls (REG-RWs) along Thika Road (A2).

The Consultant’s derivations based on the analysis of the services required as stipulated above indicate that the objectives of the assignment can only be achieved through innovatively designed research and testing regimes. Consequently, identifying the crucial tasks for this assignment based on the Scope of the Study within the TOR, the Consultant concentrated on deriving the aspects that require innovation and retrospectively developed the methodology and work plan on this basis.

The proposed methodology takes into account the specialized nature of the assignment in compliance with the TOR of the RFP.

The major tasks identified and their reciprocal individual analyses are presented in the subsequent Section 4.6. The tasks analysis is carried out in strict consideration and compliance of the RFP requirement, in general and the TOR stipulations, in particular.

In undertaking the tasks analysis, the Consultant has;

1. Definitively clarified the general and particular considerations in the RFP and TOR respectively.

2. Derived a breakdown of the Scope of Study into specific tasks and subtasks which are given in detail in Section 5.2 and 5.3 of the Work Plan presented in Chapter 5 of this Technical Proposal (refer to Tables 5.1 and 5.2).

3. Weighted each task accordingly




4. Proposed a Task Management System presented in Sub-section 5.3.2 and schematically depicted in Figure 5.1

As an integral part of the methodology to achieve the objectives of the Study, a Consultant’s Toolbook is proposed and adopted. A summary of this Toolbook is presented in Table 5.4 under Section 5.8 of this Technical Proposal whereas the Tools are included the Appendices contained in Volume II of the Technical Proposal.

The Consultant adopts these tools and his experience, which he developed through long-term Research and Development (R&D) activities within the East and Central Africa Region, to undertake the following.

1. Generate the relevant and appropriate technical approach and methodology for achieving the requirements of the Consultancy Services.

2. Establish the integral basis of the Study. 3. Propose the example of vital parameters that are paramount for the development of

Performance-based Specifications for Geosynthetics reinforced Geostructures presented in Sub-section 4.6.9.

4. Design the suitable research and testing regimes for the Study (Assignment).

In order to demonstrate the effectiveness of the methodology that is proposed in this Chapter, the Consultant has given an example of their experience in research, study, design and construction aspects of Geosynthetics reinforced geo-structures through two projects that were undertaken in Southern Sudan and Kenya. This is presented in Section 4.11.

On the other hand, the Consultant demonstrates their experience that is relevant to the development of effective performance monitoring and evaluation systems and programmes that can be adopted as a primary basis for the second topic of the RFP.

Based on the foregoing and as presented in Sub-section 4.6.3, the Consultant’s methodology largely concentrates on methods of testing and research approach that can satisfactorily realize the objectives of the Study accordingly.

4.6 Approach and Methodology to delivery of the Services required

The overall approach and methodology for achieving the objectives stipulated in the TOR of the RFP is shown in flowchart format in Figure 4.2.

d) versatility of technologies in their applications; and,

e) technologies can immensely contribute to the rapid achievement of integrated and

socio-economic development.

7.2 Recommendations

The following partial recommendations are suggested.

1. Infrastructure be considered as a topmost priority area of research.

2. Funding for research in this area be exponentially increased in order to undertake

comprehensive and extensive research for purposes of achieving rapid and useful

results.

3. Policies be established to the effect that a percentage of say 3 ~ 5% be levied on every

infrastructure project for purposes of research funding in this field.

4. Policies be established to make it mandatory that infrastructure projects only be

awarded to consulting and contracting firms that foster, develop and apply Value




Engineering Technologies as is demonstrated in sub-section 3.3.4, which outlines some

policy and contractual aspects of Value Engineering.

5. More forums such as the National Science, Technology and Innovation Week to be held

on 7 – 11 May 2012 under the NCST auspices be organized and research findings

efficiently corroborated accordingly.

6. Committees be established in the respective fields of research under the NCST for

purposes of effectively coordinating and corroborating research findings in order to

avoid duplication and unnecessary use of the much needed research funding.
