Section 1: INTRODACTION

I started my training in the (RCJY) and the duration of training was four months. I assigned to the

construction department as an inspection. And I worked on the different projects with different contractors in

the following order.

1.1 MASSCO Project.

Also I worked with (MASSCO) company around six weeks in the bridge construction. The purpose of this

project is to build five bridges to connect the support industries area with the residential area. But the important

thing for me is I improve my knowledge in the different thing like (Inspection, Plan & Design, Dewatering, Pile

Testing, Reinforcement, and Shallow Foundation).

1.2 JANCO Project.

Two weeks with (JANCO) company on the highway project. The assumed distance from this project is

(5.7km). And the main thing I learned in this couple week is (Surveying, and Asphalt paving).

1.3 SATCO Project.

Third, the last seven weeks of Co-op training I worked with (SATCO) company in the Jalmudah District.

This project is under the service department and to build four schools and one kindergarten. In these seven

weeks I learned many things about the buildings.

11

Section 2: COMPANY PROFILE

2.1 Company Overview:

Saudi Arabia’s economic growth in past decades relied on crude oil production and experts as the only

source of national income, while the natural gas associated with production operations was flared.

Recognizing that crude oil is depletable resource and those revenues are affected by supply, demand,

international, political, economic factors, the government of Saudi Arabia conducted in-depth studies upon

which the concept was laid to build an integrated industrial base that utilizes local natural resources, through the

construction of two industrial cities: Jubail on the Arabian Gulf in the east and Yanbu on the Red Sea in the

west.

To implement this concept, the Royal Commission for Jubail and Yanbu was established on 16-06-1395 H by

Royal Decree No. M/75 is for the operation, maintenance and development of the infrastructure in the two

industrial cities of Jubail and Yanbu. The Royal Commission was allocated an independent budget and given an

independent corporate character, thus becoming a unique government entity.

2.2 Company's Mission & Vision:

The mission of the RCJY is to: "Plan, promote, develop and manage Petrochemicals and Energy intensive

industrial cities through successful customer focus and partnerships with investors, employees, communities and

other stakeholders." These industrial cities are Jubail, Yanbu and the newest project Ras Al-Khair.

The best choice is for the Investors in the petrochemical and energy intensive industries and the leading

contributor to the kingdom’s growth.

http://en.wikipedia.org/wiki/Yanbu

http://en.wikipedia.org/wiki/Ras_Al-Khair

12

2.3 Company's Location:

The Commission is governed by a Board of Directors and its Chairman reports to the Council of Ministers.

The Chairman’s office in Riyadh formulates policies and oversees implementation through two Directorate

Generals in; one in Jubail and the other in Yanbu.

2.4 Company's Employees:

The Royal Commission workforce is close to 57,000 employees from over 70 different nationalities from all

around the world, 87% are Saudi nationals with 13% expatriates employed in a highly skilled professional

discipline. The ratio of technical support staff is 62.38%.

2.7 Company's Functionality and Roles:

Royal Commission was entrusted with responsibility for the planning, construction, and development of the

infrastructure facilities of the two industrial cities in Jubail and Yanbu.

During the past three decades the Jubail and Yanbu industrial cities have achieved a major breakthrough by

the collaboration with Saudi Basic Industries Corporation (SABIC), Saudi Armco, Saudi Private Sector and the

International Companies in the field of petrochemical, basic energy intensive industries and downstream

industries, which has ranked Saudi Arabia on a par with other major industrial cities in the petrochemical world.

It has undertaken a new industrial expansion in both industrial cities through the master planning and

construction of two major projects, Jubail II and Yanbu II, as one of the Kingdom’s mega development projects.

This will represent a significant economic leap which will double the land are for new investment. This will also

focus on creating a suitable environment for more participation by the private sector and the attracted local and

foreign investment for long term growth in Saudi Arabia.

13

The Royal Commission works closely with its strategic partners promote investment and to develop the

industries in Jubail Industrial City into an integrated group of companies, or clusters. This is in order for the city

to achieve excellence in technology and to accomplish one of the Kingdom’s development goals by

transforming the kingdom from an oil gas producer into a global industrial competitor.

2.7 Company's Departments:

My field training department is a construction department (CD), which is consists of four sections and each

section specializing in something different of the other section. But I will discuss the two sections I worked with

it.

2.7.1 Site Preparation, Roads and in JIC & RIC (SPR&R).

SPR&R is executing construction contracts in Jubail Industrial City (JIC) and Ras AL-Khair

Industrial City (RIC). SPR&R managed 26 active contracts valued at $1.2B,

achieved initial Acceptance with nine contracts of $250M, and financially closed-out seven

contracts valued at $180M.

2.7.1.1 Site Preparation (SP).

Site Preparation contracts in JIC & RIC are still in full gear. They completed some contracts in

JIC in preparation for Site Development and Housing Contracts with some still under

construction. The completions of site preparation contracts in RIC are very crucial to the future

site development and future facilities contracts such as (Construction of Sewage Treatment Plant,

Industrial Waste Treatment Plant, and Electrical Substations).

2.7.1.2 Roads.

The new Road Network which is under construction is part of the Royal Commission's Master

Plane that links highways to the community areas and aims to reduce the traffic jams that exist at

the current highways.

14

In this section I worked eight weeks in two different projects like as I mention before. Six weeks

in the bridge construction and two weeks in highway construction.

2.7.2 The Services Department.

During the year, over 20 contracts worth $400 million were managed, with an achieved expenditure

of $91 million. The Services Division is currently managing 17 active contracts (valued over $267

million) with 5 contracts in the closeout phase (valued at $60 million).

They have over 100 different site locations which includes many types of new buildings, such as

{Apartment Buildings, Fire Stations, Schools, Full Service Clinics with Pharmacies, Neighborhood

Centers including Mosques and Government Buildings for the Ministry of Interior.

In addition to the above, they are also involved in some Civil/Site Infrastructure work and the

renovation of several existing Buildings.

And In this section I worked seven weeks in the school projects for Jalmudah District.

15

Section 3: DETAILS OF TRAINING EXPERIENCE

First I will talk about the skills I learned from bridges project, then the highway and the building project.

3.1 Skill: Plan & Design.

3.1.1 Description.

It's a diagram contains notes, symbols, and graphs to explain and describes the project, which

will be built. The one project contains a many diffident types of plans such as (General Notes,

Foundation Plan, and Wall Footing Plan, Elevation, and Finishing plan).

3.1.2 Duration.

The duration of training to learn this skill was two weeks.

3.1.3 Nature of Work.

As an engineer for the site we didn't design the plans or make changes on it, but we read,

understand, and Implement the plans. However, if we need some change in the plans we

consult with architect department.

3.1.4 Gained Skills.

I learned how can connect between the plans of one structure .And how can apply it to the site

of a structure.

16

3.2 Skill: Inspection.

3.2.1 Description.

Inspection engineer is a general term that can have various meanings. But in engineering

work inspection involves the measurements, plan, test, dimensions, and specific conditions that

the owner and the contractor both are agreeing to.

3.2.2 Duration.

Actually there is no specific duration of this skill, because my job in this Co-op training as

Inspection engineer. So at every week I learned something new about the inspection.


Before the inspection the engineer should be checked if there any change in the plan, contract,

specific conditions, and review the last of the material.

During inspection the inspector must check only approved materials, dimensions, location,

length, size, spacing, and clearances of the side.

After inspection if there anything not correct and unacceptable work, immediately advice

supervision and contractor to correct the deficiencies.


I learned from this skill how can I inspect of some filed on the project and the testing such as

(Reinforcement, slump test, pile test, casting concrete, and so on). To be careful of some

contractors that may be cheated us in the different way like in materials, and type of concrete.

17

3.3 Skill: Dewatering.

3.3.1 Description.

Dewatering is the removal water from the workplace until the project completed by wet

classification, and filtration.

3.3.2 Duration.

The duration of training to learn this skill was one week.

3.3.3 Nature Work.

Digging deep holes around the area that has water, then insert a small tube in this hole. After that,

connects that tube together with the pump, then the pump start draws the water out through the

tubes in the other place, (Figure 3-1) illustrates this process.

Fig 3-1: The Dewatering Methodology.


I learned where can use the dewatering and the work procedure for it.

Small Tubes

Deep Holes

18

3.4 Skill: Reinforcements.

3.4.1 Description.

Is the different types and dimensions of steel used in the (Piles, Foundation, Columns,

Beams, Walls, Slabs, and So on…). This steel rebar is used to control it from getting reflected

laterally or buckle and to resist the tension.

3.4.2 Duration.

The duration of training to learn this skill continued till the end of training. Because every

week I learned different type of reinforcement.


The natural work for the reinforcement is a difference in each part of the building or the

bridge. Because every part has a different design and procedure to do it, but I can give one

example for it like the reinforcement in the (Slabs & Roof).

The Procedure of Slab Reinforcement.

The type of slab we are constructed in our project is Hordy Slab (Drop Beam Slab);

show (Figure 3-2).

Fig 3-2: Hordy Slab (Drop Beam Slab).

Drop Beam

Slab

19

After we finish the form sheet, (Figure 3-3), of the slab we started preparing the

reinforcement of beams, then for the slab.

Fig 3-3: Form sheets.

On the roof we start with the bottom rebars and, supposed to do not touch the form

sheet, so the rebars base on spacer has a thickness (3 cm).

The second thing is the upper rebars of the slab and this become above the form sheet

around (5 cm).

The final thing is connected the slab rebar with the beams, (Figure 3-4).


The different types of reinforcement.

The procedure of distribution the reinforcement in the different parts of building or the bridges.

3.5 Skill: Foundations.

3.5.1 Pile Testing.

3.5.1.1 Description.

The pile is a structure under the ground use in the different projects like high storage

buildings, and bridges to carry the load and support the project over it.

The pile testing is used to determine the relationship between load and settlement. Also,

to verify the capacity of a pile exceeds the specified load the constant rate to determine

pile bearing capacity.

3.5.1.2 Duration.


3.5.1.3 Nature of Work.

Before starting the pile test we should build one pile, then after one month or more we

can start the test.

The test takes twenty four hours in two parts. The first part takes 12hr and that's called

loading sections. The weight measure with percentage starts with (0% - 200%), then start

the unloading section, (Figure 3-5).

Fig 3-5: The load over pile.

22

The machine used for the pile test is a hydraulic machine with four scales used to

measure the load and the settlement, (Figure 3-6), (Figure 3-7) & (Figure 3-8).

Fig 3-6: The Hydraulic Machine.

Fig. 3.7: Pressure Gauge. Fig. 3.8: Settlement Scale.

We take the settlement reading from all the scale, and then take the average for the final

reading.

3.5.1.4 Gained Skills.

In this skill I connect between the theories that were studied before with the practical.

Also I inspect to this test and I learned the producer of it.

23

3.5.2 Shallow Foundations.

3.5.2.1 Description.

In this Co-op training I worked with two types of Foundation. The first one is the bridge

foundation, and the second one is building a foundation.

In the bridge foundation we used under it piles to support and carry the load. However,

the procedure of this type of foundation is different than other types.

3.5.2.2 Duration.

The duration of training to learn this skill was two weeks on the bridge project and one

week in the building project.

3.5.2.3 Nature of Work.

The Procedure of Bridge Foundation.

The first step is preparing the reinforcement and casting the piles, and each pile has a

deep in the ground around (20 – 21m).

After that, start the reinforcement of the foundation by reference to the design, (Fig 3-9).

Fig 3-9: The Reinforcement of Bridge Foundation.

The last step is casting the concrete and the waterproofing, (Figure 3-10).

24

Fig 3-10: The Waterproofing of Foundation.

The Procedure of Building Foundation.

We start constructing the blending foundation, and it has a thickness around (10 cm)

and thus made of concrete only.

After that, makes the shutter then the reinforcement. Then started casting the concrete and

the thickness of it around (60 cm - 1m) depended of design.

Over this foundation started the grade beam. This beam connects each foundation

together (columns).

Then fill the area between the grade beams by soil and compact it. After that, also cast the

blinding for grade wall, (Figure Fig 3-11). Then the last layer of grade wall (Slab on

Grade) becomes over the blinding and it has a thickness around (10 - 30 cm) with

reinforcement, (Figure 3-12).

25

Fig 3-11: Blinding Grade Wall.

Fig 3-12: Slab on Grade.

3.5.2.4 Gained Skills.

I learned the different types of foundation like (Spread Foundation, Mat/Raft Foundation,

Isolated Footing, and Pile).

The construction procedure for each type.

The design and dimensions of each one.

26

Fig 3-13: Final Shape of Foundation.

27

3.6 Skill: Surveying.

3.6.1 Description.

The surveying is a measurement of dimensional as of horizontal distances, elevations, directions,

and angles on the earth's surface especially used in highways, construction, maps.

3.6.2 Duration.



First by using the maps of the project area the survey engineer can determine the location, and

what you need to measure.

Then, we go to the area that needs to land survey like measure the distances, elevations, and the

slope road.

After the completion of the fieldwork, the field notes are brought back to the office. So that notes

used to compare and studying the maps of the location.

Also that note may be used to make a change in the design or the location of the highway.

The final step is to have the drawings signed by the client and the owner of the project.


I learned how can I use the (Total station survey) and balance it before using it. Also for what use

it like in this situation to measure the elevation, distance, and slope of the road (Figure 3-14),

(Figure 3-15).

28

29

3.7 Skill: Asphalt Paving.

3.7.1 Description.

The asphalt consists four layers and these layers consists a mixture of the aggregates sand,

gravel, and tar. Also those materials have a different size, conditions, and composition.

3.7.2 Duration.



The Procedure of Asphalt Paving.

The four layers of the asphalt pavement are arranged as follows:

Sub-Grade: This layer of soil would be excavated up to the required depth,

and this layer is selected suitable materials like sand. Then placed and

compacted in layer by layer and each layer has a thickness around (300mm).

Sub-Base Course: The thickness of this layer is (300mm), and this layer is the

final layer of the sub-grade. The materials use it for this layer is a mixture of

hard, durable particles of stone or gravel, free from dirt, clay balls, and organic

matters, (Figure 3-16).

Base Course: That thickens for this layer is (200mm), and the materials shall

be naturally occurring material, angular crushed stone, clean and free

unsuitable material, mixture of crushed gravel, and sand.

30

Asphalt: The asphalt consists two parts of its base course –asphalt and surface

asphalt. The materials used for this two layer is almost same but the difference

in the size.


I learned about the different layers of the asphalt, the work methodology of each one, and the

materials for it.

Fig 3-16: Sub-Base Course / Sub-Grade.

31

3.8 Skill: Columns.

3.8.1 Description.

The column is an upright pillar and it supports a beam or, roof, or can use it to give a beautiful

look like decorative. Also the columns consist of three parts (Base, Shaft, and Capital).

3.8.2 Duration.


3.8.3 Nature Work.

The columns should base on the footing foundation, and the type of foundation in this project is

an isolated footing.

After finished from the footing foundation of the columns there is some part of steel called

dowels. And that dowels use it to connect with the shaft.

Then started to reinforce the shaft with a rebars of steel, and connecting the rebars together by

the stirrup, (Figure 3-17).

After that become the shutter, and then the last thing casting the concrete for the shaft and after

the (48 hour) will remove the shutter. Then start the curing up to seven days, (Figure 3-18),

(Figure 3-19), (Figure 3-20).

34

3.9 Skill: Casting Concreting.

3.9.1 Description.

The concrete is a mixture of different materials made primarily with fine aggregates, coarse

aggregates, cement, water, and sometimes a mixture to improve the concrete.

All this amount of these materials must be calculated carefully to fit the design of the structure.

3.9.2 Duration.



In my Co-op training I inspect in different casting concreting of structure like foundation

(Figure 3-25), columns, beams, and slabs. But the procedure for all that is a smaller, so

take the casting concrete in the slab as an example.

Before Concreting: The trucks mixture should come by specific condition of concrete

that match the design. After that, the inspecting engineer should take the temperature and

do the slumps test for each truck, (Figure 3-21). Also the place we need to cast concrete

on it should be clean from the dust and dirt like iron filings or some small pieces of wood.

Fig 3-21: Slump Test.

35

During Concreting: Then starts pumping the concrete through pipe to the place of the

structure, (Figure 3-22). Also the workers start using the vibration machine to mix the

concrete layers together very well, (Figure 3-23).

3.10 Skill: Precast.

3.10.1 Description.

Precast is a concrete structure that is manufactured at a plant depending on the design and

specifications, then transported to the project site, (Figure 3-26).

3.10.2 Duration.



As inspector engineer we didn’t care about the details of the design, but the thing cares about the

final shape of the precast like (Finishing, Thickness, and Elevation).

Also we inspect to loading the precast by the crane, and put in its place.

Also the way to install the precast in the base and the slab.


Where we can use it, and why like when the need of the project quickness, flexibility, and if we

have a big project such as {factories, company, and residential complex}.

The different between the precast and Traditional Construction.

The advantages and the disadvantages of the precast.

Section 5: Conclusion

Training in a large company like (RCJY) was a great opportunity for me to add a lot of knowledge

and skills. It was truly enriching experience that elaborated my technical and interpersonal skills despite

the short period of training, it improved my understanding of the workplace and the work environment,

keep in touch with modern information about the civil and thinking logically and creatively to solve

problems.

Moreover, the training improved my performance, so that I can progress toward my future goals. This

was obtained by continuous support and encouragement from the parents, supervisor, and colleagues.

Field Training is one of the best plans to prepare non-graduate student to face real work environment;

therefore, I believe that training in (RCJY) can be very useful for students, since it has plenty of useful

resources, availability of training tools, capable staff to train university students, and many projects

under construction.
