CHAPTER 1. INTRODUCTION
1.1 PROJECT BACKGROUND
Indian Academy of Highway Engineers (IAHE), premium organisation under the aeigis
of Ministry of Road Transport & Highways (MORTH) has undertaken formulation of
Detailed Project Reports (DPR)in Phase I, in the states of Maharashtra, Karnataka,
Gujrat, Chattisgarh and Rajasthan. In the state of Karnataka, NH-66 near Baindur –
Kollur – Hosanagara – Anandpur – Shikaripur - Masur – NH48 near Ranebennur forms
an important artery for movement of goods from Hospet and Bellary towards Mangalore.
In the absence of a well developed highway, presently, all goods carrying vehicles going
to the port of Mangalore proceed via Shimoga, taking a more circuitous route involving
extra travel through forest area , wild life sanctuaries and hilly terrain. Thus there is a
long-felt need to provide a more direct link to Hubli- Dharwad and other parts of
northern Karnataka to Mangalore port with a National Highway. This project
alignment, recently upgraded as NH 766 C, linking NH 66 near Baindur to NH48 near
Ranebennur is an amalgamation of erstwhile five State Highways (SH) and one
National Highway (NH), namely SH 26, SH 27, SH 52, SH 1, NH 206 and SH 57. The
project alignment is spanning through three districts with a total length of
approximately 198.5 Kms, out of which approximately 37.7 kms runs in Udupi district,
123.2 kms runs in Shimoga district and 37.6 kms runs in Hubli district. Currently the
existing highway is built to SH S/l specification and the proposal is to upgrade this to
NH Double Lane (D/l) specification. The existing alignment passes through a number of
reserve forests and as also through a wildlife sanctuary. In addition a number of major
and minor bridges exist which require upgradation. Also, the towns of Kollur,
Hosanagara, Shikaripur, Masur and Halageri are mid sized towns falling along the
alignment, are developing population centres and would need to be bypassed for smooth
flow of traffic.
It is appreciated that over a horizon of next 20-30 years, this road will serve a critical
purpose of linking Mangalore and mining areas of Bellary and Hospet thus contributing
substantially towards development of the local economy. Further a number of remote
villages are also being provided connectivity under the PMGSY and the take-off points
emanate from this highway.

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 14
We foresee that there are number of constraints that would influence the design of the
project road. Those constraints are:
• Preferring to be within the ROW in case of sharp curves and other improvements.
• To retain any existing Bridge/structures.
• To obviate passing through Forest, etc.
• To initiate a separate study for river training work, river course change &
management and geological, geophysical characteristics of the region.
• Any foreseen hindrance expected for carrying out the design or deviation from
Standard designs for easy implementation.
Therefore, a design philosophy is to be prepared listing out the constraints where IRC
guidelines can be compromised. Design philosophy would be the guiding line to achieve
the objective of this project which is complying with IRC norms within the threshold of
developed criteria wherever possible.
However, even after ascertaining the various pros and cons of each individual
problems/deviation from standards, the final decision from the client would help the
consultants to finalise the design philosophy. We would look forward for such a
discussion with the client (IAHE) at an early date.

2.5 TERRAIN
The project alignment passes through a varied terrain varying from plains to hilly to
rolling plains including a wild life sanctuary. From the starting point of the project road
NH – 66 near Baindur, the project road passes through the plain terrain upto
Arashiruru, chainage 14+000 and the hilly terrain starts from Arashiruru upto Nagara,
chainage 70+600 subsequently, the plain terrain continues from Nagara to NH – 48 near
Ranebennur, chainage 198+500. The sharp bend curves start from near Kollur,
Chainage 27+000 and ends at near Nagodi, Chainage 39+500. Almost 60% of the
alignment passes through forests ,which are either reserve or protected or even wild life
preserves .Figure 2.8 shows the key plan of the terrain along the project alignment.

2.6 LAND USE
The largest proportion of land abutting the alignment is forest land followed by
agricultural and then built-up areas. The forest area starts largely from Thaggarse,
Chainage 3+000, and continues upto Dam-Hosur, Chainage 132+500. For ease of
comprehension the project alignment is divided into four Segments. Table 2.2 and Table
2.3 shows the length in kms of Forest land, Agriculture or open land and Residential or
Commercial land.

2.7 BUILT – UP AREAS
As mentioned earlier, Kollur, Hosanagara, Anandapur, Shikaripura and Masur are
major settlements along the alignment. These towns are presently midsize towns but
are likely to grow in size subsequent to upgradation of the highway. It is anticipated
that both passenger and goods traffic is likely to increase substantially and the existing
alignment is likely to create substantial bottlenecks in negotiating the builtup areas. As
such it is felt that some of the towns would need a bypass to facilitate smooth flow of
traffic. At towns of Kollur, Hosanagara, Shikaripura, Masur and at Halageri, a fresh
alignment for bypass is proposed. The proposed bypass alignments will be finalized
based on topographic surveys and design considerations.
A detailed list of built up areas and villages along the project alignment is given in the
Table 2.4 below.

2.8 CARRIAGEWAY WIDTH
There is a substantial variation in the profile of the carriageway along the project
corridor.The project highway is largely an Intermediate lane carriageway f at the
starting point from Ch: 0+000 to 25+600 for about 25.6 Km. Then the carriageway
subsequently changes from Intermediate lane to Single and Two lane undivided
carriageway up to the end of the project. Also the alignment traverses through forest
area with variations in carriageway profiles.. The pattern of existing carriageway for
single lane, Intermediate lane and Two lane is shown below in the Table 2.5 and Figure
2.9 to Figure 2.12 in the form of cross-sections.

The details of existing width of carriageway along the project length is shown above in
Table 2.5. It is noticed that more than three fourth of the project length consists of
intermediate lane width configuration.
2.9 EMBANKMENT HEIGHT
The embankment height of the carriageway varies between 0.5-3.0 metres along the
complete length of the project. The project is generally devoid of any high embankments
except for certain approaches to major bridges. The height varies between being at
ground level in some built up stretches to about 5m in the approaches of some of the
major bridges. In the hilly terrain portion of the project road, it has been observed that
the sharp bend curves are formed from near Kollur, chainage 27+000 to near Nagara,
chainage 70+600, Nagara.
2.10 HORIZONTAL ALIGNMENT
The highway basically follows the alignment of MDR upgraded from ODR over the
years. Most of the places the alignment is over steep curves and sharp bends which
would need improvement as per the geometric requirement of NH Two lane/Four lane
specifications. The details of sharp curves which require improvement is shown below in
the Table 2.6. In accordance with provisions of clause 2.2 of IRC SP:73-2007,the existing
alignment would be examined and realignment suggested where essential. As can be
seen from the table below, there are a large number of chainages which will require
curve improvement. In certain cases realignment may also be required.

It is quite apparent from the table above that out of total length of 198.5 kms
approximate 38 .00 kms only has the requisite specifications for design speed of 100 kms
as per IRC SP: 73-2007. Segment wise details are indicated in the table below. It is
evident that almost 80% of the project alignment will have to be re-designed keeping in
view the laid down specifications.

2.11 VERTICAL ALIGNMENT
The vertical geometry is an issue of significance.Especially in the ghat section
substantial improvement in the vertical profile will be required.This issue will be more
clear once the details of topographical survey are available. It may be pointed out that
the vertical profile appears to confirm to the Stopping Sight Distance and not the
Intermediate sight distances.
2.12 JUNCTIONS
Few roads intersect the project highway. All intersections are major intersection with
state highways or MDR crossing the project alignment and minor intersections with
village road intersecting the project alignment. The details on above are given in Table
2.8.

2.13 PAVEMENT CONDITION
The carriageway width of the roads has four specifications of 7.0 meters, 6.0 meters, 5.5
meters and 3.75 meters with 1.5 meters of earthen shoulders on either side. Visual
inspection of the road showed a generally good surface condition. Works related to
resurfacing have been carried out recently in certain places. Approximate 20-30 % of the
highway accepts damaged riding surface. The details on above are given in Table 2.9.

2.14 STATUS OF RIGHT OF WAY (ROW)
Major portion of the highway is aligned through the forest areas. Preliminary look of the
alignment has shown existence of ROW pillars marked at few places on either side of
the road at approx 100 mtrs interval. As could be ascertained from local PWD
authorities, it appears that approx 5.0 to 10.0 mtrs only on either side of the centre line,
land has been acquired. Thus the existing right of way (ROW) extends to total width of
only 10 -20 mtrs only as against requirement of 45 mtrs. .Resultantly,there will be
substantial requirement of LA all along the project corridor to meet the design criteria
and development of the highway as per norms laid down vide IRC 73 and IRC 86 for
urban and non urban areas. On either side of the earthen shoulders there is a presence
of a number of trees within the ROW. Most of the places only earthen drain was noticed
.Also in some portions ,OFC could be noticed laid on the outer edge of the ROW. Details
of existing ROW along the project alignment is indicated below in the Table 2.10.

2.15 SOIL AND SUBSOIL
The soil characteristics seem to be non-uniform along the project alignment and varies
from Red soil from km 0.0 to km 14.0, Laterite soil mixed with Silty clay from km 14.0 to
130.0, Block cotton soil from km 130.0 to 198.5. Such variation in soil characteristics will
imply substantial variation in embankment/subgrade designs. As regards the water
table, inspection of wells showed water at roughly 5m from the natural ground. The
river beds are generally sandy and used for quarrying.
2.16 UTILITIES ALONG THE PROJECT HIGHWAY
OFC cable was noticed in certain places running on the outer edge of the ROW. HT line
crossings were noticed at one to two places. It is proposed to examine provision of
additional utilities e.g. bus bays, passenger facilities, toll plazas where required and
other passenger amenities.
2.17 SOCIO RELIGIOUS STRUCTURE AND BUILDINGS
The roadway is flanked on the sides by important social activity centers such as schools,
colleges, and places of worship etc. While widening, the alignment may have to be
shifted to avoid impacting these structures.
2.18 BRIDGES AND CROSS DRAINAGE STRUCTURES
The inventory data for the existing cross drainage structures, culverts and bridges were
carried out. The project road has 2 Major bridge, 60 Minor bridges, 322 Culverts, 1
Aqueduct and the summary of the same is given below in Table 2.11.

2.19 LEVEL CROSSING and ROB
The project road starts from NH-66 near Baindur and ends at NH-48 near Ranebennur
over a length of 198.5 Kms. Existing ROB is located at Taggarse, Chainage 1+150 and
have a formation width of 10 mts and height of 5.5 mts. As regards the level crossing it
is located at Anandapur, Chainage 113+200. The level crossing is approximately 200
mts from the road junction on NH 206. Thus the ROB will have to be so designed that it
merges with the road junction and facilitates smooth flow of traffic in different
directions.

The widening/improvement work to 2/4 laning will be explored to fit within the existing
right of way avoiding land acquisition, except for locations having inadequate width and
where provisions of short bypasses, service roads, alignment corrections, improvement of
intersections are considered necessary and practicable and cost effective. However
bypass proposals will also be considered, wherever in urban areas, improvement to 2/4
lane of the existing road is not possible. The land acquisition details as per revenue
records/maps and as required in ToR will also be furnished.
Consultants have in-house latest computers/laptops loaded with software for the design
of Alignment, Roadway, Bridges, steel structures, geotechnical analysis.
Consultants also have NABL accredited in-house material testing laboratory to ensure
that the material are tested with proper procedures and consistency in results which
will help in accurate design of pavement, embankment and structures
3.4 QUALITY ASSURANCE SYSTEM FOR CONSULTANCY ASSIGNMENT
It is of great importance to maintain consistency in design, careful preparation of
drawings and infallible design work of any projects by the consultants. The quality of
this work is a vital ingredient in the successful completion of design work and
implementation of the project both for the new highways and for upgrading and
maintaining the existing roads
Our company is an ISO 9001:2008 certified company, our edge in terms of delivering
high quality products requires effective quality assurance mechanisms. For this we have
developed and are applying a quality assurance system, which is compliant with ISO
9001:2008. Our quality assurance systems may be divided into three phases:
1) Pre-implementation phase
2) Implementation
3) Quality assurance of outputs
At the pre-implementation phase the Team Leader will focus on: (a) ensuring that there
is a clear understanding of the ToR and the expectations of the client of the required
work and outputs, and (b) that the team members identified for the assignment are fully
qualified to undertake the assignment. The company will develop the Quality Assurance
Plan (QAP) for all field studies including topographic surveys, traffic surveys,
engineering surveys and investigations and documentation activities. The detailed QAP

Classified Traffic Volume Count Survey
The classified traffic volume count surveys will be carried out for 7 days (continuous,
direction-wise) at the selected survey stations. The vehicle classification system as given
in relevant IRC code will be followed. However, the following generalised classification
system is suggested in view of the requirements of traffic demand estimates and
economic analysis:
Motorised Traffic Non-Motorised Traffic
2 Wheeler Bi-Cycle
3 Wheeler Cycle-Rickshaw
Passenger Car Animal Drawn Vehicle (ADV)
Utility Vehicle (Jeep, Van etc) Hand Cart
Bus Mini Bus Other Non-Motorised Vehicle
Standard Bus
LCV LCV – Passenger
LCV – Freight
Truck
MCV - 2 Axle Rigid Chassis
HCV - 3 Axle Rigid Chassis
MAV - Semi Articulated
MAV - Articulated
All results will be presented in tabular and graphical form. The survey data will be
analysed to bring out the hourly and daily variations. The traffic volume count per day
will be averaged to show a weekly Average Daily Traffic (ADT) by vehicle type. The
Annual Average Daily Traffic (AADT) will be worked out by applying seasonal factors.
The consultants will compile the relevant traffic volume data from secondary sources
also. The salient features of traffic volume characteristics will be brought out and
variations if any, from the traffic census carried out by the State PWD will be suitably
explained.

Origin-Destination (O-D) and Commodity Movements Surveys
The Consultants will carry out 1-day (24 hour, both directions) O-D and Commodity
Movement Surveys at locations finalized in consultation with IAHE. These will be
essentially required around congested towns to delineate through traffic. The road side
interviews will be on random sample basis and cover all four-wheeled vehicles. The
locations of the O-D survey and Commodity Movement surveys will normally be same as
for the classified traffic count stations.
The location of origin and destination zones will be determined in relation to each
individual station and the possibility of traffic diversion to the Project Road from/to
other road routes including bypasses.
The trip matrices will be worked out for each vehicle type information on weight for
trucks would be summed up by commodity type and the results tabulated, giving total
weight and average weight per truck for the various commodity types. The sample size
for each vehicle type will be indicated on the table and also in the graphical
representations.
The data derived from surveys will also be analysed to bring out the lead and load
characteristics and desire line diagrams. The data analysis would also bring out the
requirement for the construction of bypasses. The distribution of lead and load obtained
from the surveys will be compared with those derived from the axle load studies. The
commodity movement data will be taken into consideration while making the traffic
demand estimates.
Turning Movement Surveys
The turning movement surveys for estimation of peak hour traffic for the design of
major and minor intersections will be carried out for the Study. The details regarding
composition and directional movement of traffic will be furnished.
The methodology for the surveys will be as per IRC: SP: 41-1994. The details including
location and duration of surveys will be finalized in consultation with IAHE officials.
The data derived from the survey will be analysed to identify requirements of suitable
remedial measures, such as construction of underpasses, fly-overs, interchanges, grade-
separated intersections along the project road alignment. Intersections with high traffic
volume requiring special treatments either presently or in future will be identified.

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 68
Axle Load Surveys
Axle load surveys in both directions will be carried out at suitable location(s) in the
project road stretch on a random sample basis normally for trucks only (both empty and
loaded trucks) for 2 normal days - (24 hours) at special count stations to be finalised in
consultation with IAHE. However, a few buses may be weighed in order to get an idea
about their loading behavior. While selecting the location(s) of axle load survey
station(s), the locations of existing bridges with load restrictions, if any, should be taken
into account and such sites should be avoided.
The axle load surveys will be done using axle load pads or other sophisticated
instruments. The location(s) of count station(s) and the survey methodology including
the data formats and the instrument type to be used will be finalised before taking up
the axle load surveys.
The axle load data should be collected axle configuration-wise. The number of equivalent
standard axles per truck will be calculated on the basis of results obtained. The results
of the survey would bring out the VDF for each truck type (axle configuration, if the
calculated VDF is found to be below the national average, then national average will be
used. Furthermore, the data from axle load surveys are analysed to bring out the Gross
Vehicle Weight (GVW) and Single Axle Load (SAL) Distributions by truck type (axle
configuration).
Speed-Delay Surveys
The Consultants will carry out appropriate field studies such as moving car survey to
determine running speed and journey speed. The data would be analysed to identify
sections with typical traffic flow problems and congestion. The objective of the survey is
to recommend suitable measures for segregation of local traffic, smooth flow of through
traffic and traffic safety. These measures would include the provision of bypasses,
under-passes, fly-overs, interchanges, grade-separated intersections and service roads.
Traffic Demand Estimates
The consultants will make traffic demand estimates and establish possible traffic
growth rates in respect of all categories of vehicles, taking into account the past trends,
annual population and real per capita growth rate, elasticity of transport demand in
relation to income and estimated annual production increase. The other aspects
including socio-economic development plans and the land use patterns of the region

having impact on the traffic growth, the projections of vehicle manufacturing industry in
the country, development plans for the other modes of transport, O-D and commodity
movement behavior are also be taken into account while working out the traffic demand
estimates.
The values of elasticity of transport demand will be based on the prevailing practices in
the country. The Consultants will give complete background including references for
selecting the value of transport demand elasticity.
It is envisaged that the 2/4-laning of the project road sections would be completed and
opened to traffic after 3 years. The traffic demand estimates will be done for a further
period of 30 years from completion of two/four lane. The demand estimates will be done
assuming three scenarios, namely, optimistic, pessimistic and most likely traffic growth.
The growth factors will be worked out for five-yearly intervals.
Traffic projections would be based on sound and proven forecasting techniques. The
traffic projections would also bring out the possible impact of implementation of any
competing facility in the near future. The demand estimates should also take into
account the freight and passenger traffic along the major corridors that may
interconnect with the project. Impact of toll charges on the traffic estimates should be
estimated.
The methodology for traffic demand estimates described in the preceding paragraphs is
for normal traffic only. In addition to the estimates for normal traffic, the Consultants
will work out the estimates for generated, induced and diverted traffic. The traffic
forecasts will also be made for both diverted and generated traffic. Overall traffic
forecast thus made will form the basis for the design of each pavement type and other
facilities/ ancillary works.

Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 70
B.1 Reconnaissance and Alignment
The Consultants would make an in-depth study of the available land width (ROW)
topographic maps, satellite imageries and air photographs of the project area, geological
maps, catchment area maps, contour plans, flood flow data and seismological data. And
other available relevant information collected by them concerning the existing
alignment. Would make efforts for minimizing land acquisition.
The detailed ground reconnaissance may be taken up immediately after the study of
maps and other data.
The data derived from the reconnaissance surveys are utilised for planning and
programming the detailed surveys and investigations. All field studies including the
traffic surveys should be taken up on the basis of information derived from the
reconnaissance surveys.
The data and information obtained from the reconnaissance surveys will be documented.
The data obtained from the reconnaissance surveys should form the core of the database
which would be supplemented and augmented using the data obtained from detailed
field studies and investigations.
B.2 Topographic Surveys
The basic objective of the topographic survey would be to capture the essential ground
features along the alignment in order to consider improvements and for working out
improvements, rehabilitation and upgrading costs. The detailed topographic surveys will
be taken up after the completion of reconnaissance surveys.
The detailed field surveys will be carried out using Total stations. The data from the
topographic surveys will be available in (x, y, z) format for use in a sophisticated digital
terrain model (DTM).
The detailed field surveys would essentially include the following activities
Topographic Surveys along the Existing Right of Way (ROW): Running a
continuous open Traverse along the existing road and realignments, wherever
required, and fixation of all cardinal points such as horizontal intersection points
(HIP’s), centre points and transit points etc. and properly referencing the same
with a pair of reference pillars fixed on either side of the centre-line at safe places
within the ROW.
The detailed field surveys would essentially include the topographic surveys
along the proposed location of bridge and alignment of approach road.

underground), huts, buildings, fencing and trees (with girth greater than
0.3metre) oil and gas lines etc. falling within the extent of survey.
The width of survey corridor will generally be as given under
The width of the survey corridor should take into account the layout of the
existing alignment including the extent of embankment and cut slopes and the
general ground profile. While carrying out the field surveys, the widening scheme
(i.e. right, left or symmetrical to the centre line of the existing carriageway)
should be taken into consideration so that the topographic surveys cover
sufficient width beyond the centre line of the proposed divided carriageway.
In case the reconnaissance survey reveals the need for bypassing the congested
locations, the traverse lines would be run along the possible alignments in order
to identify and select the most suitable alignment for the bypass. The detailed
topographic surveys should be carried out along the bypass alignment approved
by IAHE. At locations where grade separated intersections could be the obvious
choice, the survey area will be suitably increased. Field notes of the survey
should be maintained which would also provide information about traffic, soil,
drainage etc.
The width of the surveyed corridor will be widened appropriately where
developments and / or encroachments have resulted in a requirement for
adjustment in the alignment, or where it is felt that the existing alignment can
be improved upon through minor adjustments.
Where existing roads cross the alignments, the survey will extend a minimum of
100 m either side of the road centre line and will be of sufficient width to allow
improvements, including at grade intersection to be designed.

severs, gas/oil pipes, crossings, trees, plantations, utility services such as electric,
and telephone lines (O/H & U/G) and poles, optical fibre cables (OFC) etc. The
survey would cover the entire right-of-way of the road on the adequate allowance
for possible shifting of the central lines at some of the intersections locations.
The information collected during reconnaissance and field surveys will be shown
on a strip plan so that the proposed improvements can be appreciated and the
extent of land acquisition with L.A schedule, utility removals of each type etc.
assessed and suitable actions can be initiated. Separate strip plan for each of the
services involved shall be prepared for submission to the concerned agency.
B.3 Road and Pavement Investigations
The Consultants will carry out detailed field studies in respect of road and pavement.
The data collected through road inventory and pavement investigations should be
sufficient to meet the input requirements of HDM-IV.

The data should be collected in sufficient detail. The data should be compiled and
presented in tabular as well as graphical form. The inventory data would be stored in
computer files using simple utility packages, such as EXCEL.
Pavement Condition:
The data concerning the pavement composition may be already available with the PWD.
However, the consultants will make trial pits to ascertain the pavement composition.
For each test pit, the following information shall be recorded:
Test pit reference (Identification number, location):
Pavement composition (material type and thickness); and
Subgrade type (textural classification) and condition (dry, wet)
Road and Pavement Condition Surveys
The objective of the road and pavement condition surveys are to identify defects and
sections with similar characteristics. All defects are systematically referenced, recorded
and quantified for the purpose of determining the mode of rehabilitation.
The pavement condition surveys are carried out using visual means. Supplemented by
actual measurements and in accordance with the widely accepted methodology
(AASHTO, IRC, OECD, TRL and World Bank Publications) adapted to meet the study
requirements. The measurement of rut depth would be made using standard straight
edges.
The shoulder and embankment conditions will be evaluated by visual means and the
existence of distress modes (cuts, erosion marks, failure, drops) and extent (none,

moderate, frequent and very frequent) of such distress manifestations would be
recorded.
For sections with severe distresses, additional investigations as appropriate will be
carried out to determine the cause of such distresses.
Pavement Roughness
The roughness surveys will be carried out using Bump Integrator or similar instrument.
The methodology for the surveys will be as per the widely used standard practices. The
calibration of the instrument will be done as per the procedure given in the World
Bank’s Technical Publications and duly got authenticated by established
laboratory/institution acceptable to the client.
The surveys will be carried out along the outer wheel paths. The surveys will cover a
minimum of two runs along the wheel paths for each directions.
The results of the survey shall be expressed in terms of BI and IRI and shall be
presented in tabular and graphical forms. The processed data shall be analysed using
the cumulative difference approach to identify road segments homogenous with respect
to surface roughness.
Pavement Structural Strength
The Consultants will carry out structural strength surveys for existing pavements using
Benkelman Beam Deflection technique in accordance with the CGRA procedure given in
IRC: 81-1997 (“Guidelines for Strengthening of Flexible Road Pavements Using
Benkelman Beam Deflection Technique”).
It is suggested that the deflection surveys may be carried out as per the scheme given
below:
Mainline testing; and,
Control section testing.
The deflection tests for the mainline shall be carried out at every 500 m along the road
sections covered under the study. The control section testing shall involve carrying out
deflection testing for each 100 m long homogenous road segment along the road sections.
The selection of homogenous segment will be based on the data derived from pavement
condition surveys. The total length of such homogenous segments will not be less than
100 m per kilometer. The deflection measurements for the control section testing should
be at an interval of not more than 10 m.
Detailed Project Report for up gradation of Haveri to Baindur Section of NH- 766 C in the state of Karnataka to two / four lane with paved shoulder configuration (Package no- NH/IAHE/24)
Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 76
Test pits are taken at every 500 m and also along each homogeneous road segment to
obtain pavement composition details (pavement course, material type and thickness) so
as to be able to study if a correlation exists between deflection and composition. If so, the
relationship are to be used while working out the overlay thickness for the existing
pavement.
Benkelman Beam Deflection surveys may not be carried out for severely distressed
sections of the road warranting reconstruction. The Consultants, immediately upon the
award of the contract, will have to submit to IAHE the scheme describing the testing
schedule including the interval. The testing scheme will be supported by data from
detailed reconnaissance surveys.
Subgrade Characteristics and Strength
Based on the data derived from condition (surface condition, roughness) and structural
strength surveys, the project road section should be divided into segments homogenous
with respect to pavement condition and strength. The delineation of segments
homogenous with respect to roughness and strength should be done using the
cumulative difference approach (AASHTO, 1993).
The data on soil classification and mechanical characteristics for soils along the existing
alignments may already be available with the PWD. The testing scheme is, therefore,
proposed as given under:
For the widening (2/4 Laning) of existing road within the ROW, the
Consultants have to test at least three sub-grade soil samples for each
homogenous road segment or three samples for each soil type
encountered, whichever is more.
For the roads along new alignments, the test pits for sub grade soil shall
be @ 5km or for each soil type, whichever is more. A minimum of three
samples should be tested corresponding to each homogenous segment.
The testing for subgrade soil shall include:
i. In-situ density and moisture content at each test pit
ii. Field CBR using DCP at each test pit
iii. Characterisation (grain size and Atterberg limits) at each test pit and,
iv. Laboratory moisture-density characteristics (modified AASHTO
compaction);

Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 77
v. Laboratory CBR (unsoaked and 4-day soak compacted at three energy
levels) and swell.
For problematic soils, the testing will be more rigorous. The characteristics with regard
to permeability and consolidation will also be determined for these soils. The frequency
of sampling and testing of these soils will be finalised in consultation with the IAHE
officers after the problematic soil types are identified along the road sections. The
laboratory for testing of material should be got approved from IAHE before start of
work.
B.4 Investigation for Bridges and Structures
Inventory of Bridges, Culverts and Structures
The Consultants will carry out inventory of all the structures (bridges, viaducts,
ROBs/RUB and other grade separated structures, culverts, etc.) along the road under
the project. The inventory for the bridges, viaducts and ROBs will include the
parameters required as per the guidelines of IRC-SP: 35. The inventory of culverts will
be presented in a tabular form covering relevant physical and hydraulic parameters.
Hydraulic and Hydrological Investigations
The hydrological and hydraulic studies are to be carried out in accordance with IRC SP:
13 (“Guidelines for the Design of Small Bridges and Culverts”) and IRC: 5 (“Standard
Specifications & Code of Practice for Road Bridges, Section I General Feature of
Design”). These investigations will be carried out for all existing drainage structures
along the road sections under the study.
The consultant will also collect information on observed maximum depth of scour. In
respect of major bridges, history of hydraulic functioning of existing bridge, if any, under
flood situation, general direction of river course through structure, afflux, extent and
magnitude of flood, effect of backwater, if any, aggradation/degradation of bed, evidence
of scour etc. will be used to augment the available hydrological data. The presence of
flood control/irrigation structures, if affecting the hydraulic characteristics like causing
obliquity, concentration of flow, scour, silting of bed, change in flow levels, bed levels etc.
will be studied and considered in design of bridges. The details of any future planned
work that may affect the river hydraulics will be studied and considered.

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 78
The Consultants will make a desk study of available data on topography (topographic
maps, stereoscopic aerial photography), storm duration, rainfall statistics, top soil
characteristics, vegetation cover etc. so as to assess the catchment areas and hydraulic
parameters for all existing and proposed drainage provisions. The findings of the desk
study would be further supplemented and augmented by a reconnaissance along the
area. All important hydrological features will be noted during this field reconnaissance.
The Consultants will collect information on high flood level (HFL), low water levels
(LWL), high tide level (HTL), low tide level (LTL) where applicable, discharge velocity
etc. from available past records, local inquiries and visible signs, if any, on the
structural components and embankments. Local inquiries will also be made with regard
to the road sections getting overtopped during heavy rains.
Condition Surveys for Bridges, Culverts and Structures
1. The team will thoroughly inspect the existing structures and shall prepare a
report about their condition including all the parameters given in the Inspection
pro-forma of IRC-SP; 35. The condition and structural assessment survey of the
bridges / culverts / structures shall be carried out by senior experts of the
Consultants.
2. For the bridges identified to be in a distressed condition based upon the visual
condition survey, supplementary testing shall be carried out as per IRC-SP: 35
and IRC-SP: 40. Selection of tests may be made based on the specific requirement
of the structure.
3. The assessment of the load carrying capacity or rating of existing bridges shall be
carried out under one or more of the following scenarios:
i. When the design live load is less than that of the statutory commercial
vehicle plying or likely to ply on bridge;
ii. If during the condition assessment survey and supplementary testing the
bridge is found to indicate distress of serious nature leading to doubt
about structural and / or functional adequacy, and
iii. Design live load is not known nor are the records and drawings available.
4. The evaluation of the load carrying capacity of the bridge shall be carried out as
per IRC-SP: 37 (“Guidelines for Evaluation of Load Carrying Capacity of
Bridges”). The analytical and correlation method shall be used for the evaluation
Detailed Project Report for up gradation of Haveri to Baindur Section of NH- 766 C in the state of Karnataka to two / four lane with paved shoulder configuration (Package no- NH/IAHE/24)
Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 79
of the load carrying capacity as far as possible. When it is not possible to
determine the load carrying capacity of the bridge using analytical and
correlation method, the same shall be carried out using load testing. The
consultant has to exhaust all other methods of evaluation of strength of bridges
before recommending to take up load testing of bridges. Road closure for testing
if unavoidable shall be arranged by IAHE for limited duration say 12 hrs or so.
5. The team shall carryout necessary surveys and investigations to establish the
remaining service life of each retainable bridge or structure with and without the
proposed strengthening and rehabilitation according to acceptable international
practice in this regard.
Geo-technical Investigations and Sub-Soil Exploration
We shall carry out geo-technical investigations and sub-surface explorations for the
proposed Bridges along high embankments and any other location as necessary for
proper design of the works and conduct all relevant laboratory and field tests on soil and
rock samples.
The deviation(s), if any, by the Consultants from the scheme presented above should be
got approved from IAHE.
However, where a study of geo-technical reports and information available from
adjacent crossings over the same waterway indicates that subsurface variability is such
that boring at the suggested spacing will be insufficient to adequately define the

CHAPTER 7. DESIGN STANDARDS AND PROPOSED
CROSS-SECTIONS
7.1 INDICATIVE DESIGN STANDARDS FOR DIVIDED CARRIAGEWAY:
7.1.1 Approach
The aim is to provide maximum safety to the road users, in defining the highway
geometry, carriageway, shoulder widths, embankments and other pertinent components
for an uninterrupted and smooth flow of traffic. The approach adopted in achieving the
safety is as follows:
• Provide appropriate cross traffic facilities without impeding traffic flow;
• Use ROW only and recommend land acquisition where absolutely
essential.
• Minimize impact on roadside settlements and environment;
• Avoid adverse impacts of crowded areas along the stretch of Project road;
• Provide cost-efficient, but readily constructible facility with least
hindrances, namely, land acquisition, resettlement and rehabilitation.
7.1.2 Reference Standards
IRC Standards will be used in general. However, where IRC does not cover any
particular feature or aspect appropriately, AASHTO and other International Standards
will be used for providing additional safety, namely, length of vertical curves in view of
likely modernization of goods trucks in India (height of driver’s eye), super elevation and
radii of curve beyond which no super elevation is needed and extra widening on
horizontal curves for smaller radii. AASHTO Standards for transition curves will be
considered as appropriate.
7.2 DESIGN STANDARDS
The following paragraph presents a summary of applicable design standards and
engineering assessment in terms of:
Highway engineering Specifications and Standards
Geometric design
Intersections
Road embankment and cutting

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 112
Pavement design
Drainage and hydrological studies
Landscaping and plantation
Design of structures
7.2.1 Highway Engineering Specifications and Standards
The main Standard applicable for the design of two-Laning (with paved shoulders) of the
Project Highway shall conform to the Manual of Specifications And Standards for Two-
Laning of highways through Public Private Partnership published by the Indian Road
Congress (IRC: SP: 73-2007) Other Design standards and specifications that would
apply shall be drawn from IRC codes and guidelines and other relevant national and
international standards.
7.2.2 Geometric Design
7.2.2.1 Terrain Classification and Design Speed
The terrain in the project stretch is plain with the general cross slope of the country is
less than 10%. Based on this the recommended Project Highway would be designed for a
design speed, referred as Ruling design speed of 80 kmph in normal situations. A
Minimum design speed of 40 to 65 kmph would be adopted where site conditions are
restrictive and adequate land width is not available.
7.2.2.2 Road Land Width
Nature of land Plain & Rolling Terrain Mountainous & Steep Terrain
Normal (m) Range (m) Normal (m)
Open areas 45 30 - 60 24
Built Up areas 30 30 - 60 20
In order to avoid and limit land acquisition, the land widths will be kept to a minimum
within the above range.
7.2.2.3 Roadway Width
The width of roadway depends on the category of road and the nature of terrain through
which it passes. Though the project stretch of Baindur to Ranebennur passes through
both plain and hilly terrain, every effort will be made to maintain uniformity within the
roadway width as far as practicable.
Detailed Project Report for up gradation of Haveri to Baindur Section of NH- 766 C in the state of Karnataka to two / four lane with paved shoulder configuration (Package no- NH/IAHE/24)
Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 113
The roadway width of cross-drainage structures in plain and rolling terrain measured
from outside to outside of parapet walls should be equal to the normal roadway width in
that section. In mountainous and hilly terrain, the roadway widths are exclusive of
parapets and side drains.
On horizontal curves, the roadway width should be increased corresponding to the extra
widening of the carriageway required at the provided curvature.
7.2.2.4 Shoulder Width
A total shoulder width of 2.5m will be proposed. The 2.5m shoulder will compose of 1.5m
paved shoulder of the same composition as that of the main carriageway and 1.0m hard
shoulder composed of granular sub-base material or selected earth fill. The paved
shoulder in addition to providing lateral support to the main carriageway can also acts
as a separate lane for 2-wheeler / cycle traffic on the highway.
7.2.2.5 Pavement / Shoulder camber or cross-fall
The cross-fall in the main pavement and paved shoulder is proposed to be kept as 2.5%
and 3.0% in hard shoulder. However, on hill roads this may not be possible in every
situation, particularly in reaches with a meandering alignment where straight sections
are few and far between. In such cases, discretion may be exercised and instead of
normal camber, the carriageway may be given a uni-directional cross-fall towards the
hill side, with regard to factors such as the direction of super-elevation at the flanking
horizontal curves, ease of drainage, problem of erosion of the down-hill face, etc.
On super-elevated sections, the hard shoulder should have a rollover of 8% maximum at
the outer edge with respect to paved shoulder and a cross-fall varying from 3% to the
maximum super-elevated value on the curve at the inner edge.
7.2.2.6 Horizontal Alignment
The tangent sections, circular curve, transition curve and super elevation are the major
elements of horizontal alignment. A balanced control on the above elements is required
to provide safe and continuous flow of vehicles under the general traffic conditions.
The minimum radii of horizontal curves applicable to the Project Highway are:

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 114
Nature of Terrain Desirable Minimum Absolute Minimum
Plain 360m 230m
Rolling 230m 155m
Mountainous 90m 60m
Steep 60m 30m
The radii of horizontal curves shall not be less than desirable value except where site
conditions are restrictive and adequate length is not available. In such restrictive
conditions, the radius of curvature shall not be less than the absolute minimum radius.
7.2.2.7 Bypasses & Re-alignments
Bypasses or detours will be provided to segregate the local traffic from the through
traffic. Re-alignments are to be done at many places having sub-standard curves and to
avoid landslide zones in hilly terrain and plain terrain.
Further the examination of the project alignment indicates to the possibility of three Re
alignments at Kollur, Hosanagara, Shikaripur, Masur and Halageri.
7.2.2.8 Vertical Alignment
There are two major elements in vertical geometry of an alignment i.e. longitudinal
gradient and vertical curve. The following gradients for Plain / Rolling terrain conditions
as of Project Highway are given below.
Nature of Terrain Ruling Gradient Limiting Gradient
Plain and Rolling 3.3% 5.0%
Mountainous 5.0% 6.0%
Steep 6.0% 7.0%
7.2.2.9 Sight Distance
Visibility is an important requirement for the safety of travel on roads. The various
sight distances for design speed applicable for Project Highway is given in the table
below.

7.2.3 Road Embankment and Cutting
Embankment height generally varies from 1.2 to 3m. High embankment is generally
provided in approach to bridges. At other sections of project road embankment varies
from 1.2m to 2.0m. All high embankments will be designed from stability considerations
and adequate protection works will be provided as per the guidelines given in various
Standards.
7.2.4 Pavement Design
Although, the main highway itself is flexible paved, possibility of provision of rigid
pavements will also be explored in certain areas. “Guidelines for the Design of Plain
Jointed Rigid Pavements for Highways”, will be followed for the design of rigid
pavement while IRC: 37-2001, “Guidelines for the Design of Flexible Pavement” will be
followed for the flexible pavement designs. The IRC-37 allows both (i) full pavement
designs for 15 years and (ii) stage construction. The Consultant will establish
alternative strategies or combination of initial design, strengthening and maintenance
to provide the specified level of pavement performance.
It may be worth mentioning that new version of IRC- 37: 2012 has been published in
July 2012.
7.2.5 Drainage and Hydrological Studies
The drainage will be designed in accordance with IRC: SP: 42 - 1994 “Guidelines on
Road Drainage” and IRC: SP: 50 – 1999 “Guidelines on Urban Drainage”. The selection
on type of drain i.e. open drains (lined or unlined) and covered drains will be made
accordingly.
7.2.6 Landscaping and Plantation
Plantation adjacent to the highway is not very significant. The final design will take
plantation into consideration.

Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 116
7.2.7 Design of Structures
Structures design should be planned in such a way to optimize the design variance, site
activities and materials as well. Modular design for box structures would save by the
multiple uses of the formwork and thereby would speed up the construction process.
7.2.8 Road Safety Measures
Following IRC Codes / Guidelines will be followed:
• IRC SP 44 – 1994: Highway Safety Code.
• IRC SP 43 – 1994: Guidelines on Low Cost Traffic Management Techniques for Urban
Areas.
• IRC 79 – 1981: Recommended Practice for Road Delineators.
• IRC 70 – 1979: Guidelines on Regulation and Control of Mixed Traffic in Urban Areas.
Among others, the following measures will be considered for ensuring safety: -
• Segregation of traffic;
• Bus-stops, lay-buys for cars and trucks for rest, recuperation and attend
technical problems;
• Appropriate delineators, roadway indicators, hazard / object markers with
reflectors, road markings, traffic signals, barricades, left side refuge, passage in median
for police and fire brigades, and intersection channelisation;
7.2.9 Pedestrian and Animal Crossings
Besides the provisions of underpasses for the localities and urban areas, potential
locations for pedestrian and animal crossings will be examined in consultation with
IAHE and State PWD’s.
7.2.10 Road and Traffic Signs:
These include Signage, Road Signs / Hoardings, Road Markings, Traffic Signals and
Lighting for interchanges, raised carriageway, long bridges and urban and populated
areas.
(a) Signage
• For the safety and guidance of a driver, proper signage and delineators
are critical. Signage drawings will show guide signs and regulating signs
at appropriate locations. The signs will be of reflector type to be easily
visible in the dark.

Draft Inception Report
Infra Support Engineering Consultants Pvt. Ltd in JV with IIIE 117
• Guide signs at major junctions will be illuminate type and mounted to be
visible; lettering size and location of signposts will be for the design speed
and clear visibility. Reflectors will be used so that lanes are visible at
nighttime and different reflectors for median and lane striping will be
proposed to properly guide opposite traffic, and markings to indicate safe
distance between vehicles at different speeds.
(b) Road Signs
• All road signs shall be in conformity with the provision of IRC SP 32 –
1992 New Traffic Signs and IRC 67 – 1977 Code of Practice for Road
Signs. The signs are Mandatory / Regulatory, Cautionary / Warning and
Informatory.
• The bottom of the housing of a signal face will be 2500mm above footpath
when not suspended over roadway or 5500mm above pavement grade at
CL when suspended over roadway.
(c) Road lighting on Bridges and Urban Areas
• Lighting will be provided in the medians on roads with Central Medians;
on the edge of service roads; on high level masts at major intersections in
Urban Areas.
(d) Road Marking
The road markings will be in conformity with the IRC Standards (latest versions):
• IRC 35-1997 :Code of Practice for Road Markings with Paint;
• IRC 30-1968:Standard Letters and Numerals of Different Heights Use
in Highway Signs and
• IRC 31-1969:Route Marker Signs for State Roads
Hot applied thermoplastic paints will be proposed for better visibility and longer service
life (ref. Art 803-MOST Specifications).
However, all efforts will be made to keep up with new developments by conducting
deliberations and seminars. Frequent reference to codes and manuals are necessary to
be updated with revisions if any.

CHAPTER 13. SUMMARY AND CONCLUSION
13.1 SUMMARY
The consultant has mobilized and initial site visit was carried out in April 2015.
Complete project alignment was visited and due interaction was carried out with local
PWD officials. During the site visit, an assessment of the general terrain, condition of
pavement, type of major/minor bridges etc was carried out. Details of existing Right of
way (ROW) indicated ine the report need to be confirmed in due course as no ready
records were available. Initial appreciation of flow of traffic from neighboring towns of
Shikaripur, Anandapur, Hosanagara was carried out.The information obtained has been
tabulated in various preceding chapters. The issue of realignment and provision of
bypasses at Kollur,Hosanagara,Shikaripur, Masur and Halagiri have been duly
explained.
Depending upon the scope and timeframe available a detailed methodology and work-
program has been evolved.
13.2 CONCLUSION / NEXT STEP
It will be the endeavor of the consultant to deploy adequate resources for timely
preparation of the DPR. At frequent levels interaction with IAHE officials will be carried
out for obtaining concurrence regarding issues of importance.
