CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
This Project includes development of 6 kilometers road starting from intersection of Abu
Bakr Al-Siddiq Road with Thumama Road up to the King Salman Road. The project was for the
implementation of three bridges for cars to allow northbound and southbound movement on
intersections of Abu Bakr Al-Siddiq Road with Prince Saud Bin Muhammad Bin Miqrin Road,
Al-Thumamah Road, and Anas bin Malik Road. I had worked for the supplying the necessary
communication. I had also implemented other works necessary for the main road and the 60-
meter-wide service roads. I had also worked for the diverting the existing service networks
interfering with the project works. I had also worked on the digging of wells equipped with
dedicated pumping stations to provide irrigation water needed for the project's area.

CE 3.2.2 Objectives developed for the project
As the senior electrical engineer of the project I had set out some objectives which were
to be followed by me and my team members:
 To supervise all working of the electrical department of the construction site in accordance to

MDBs and SMDBs along with the installation of auto capacitor panels and UPS systems.
 To provide the testing of the transformers up to 30 MVA.
 To arrange and forecast the manpower and material, machines and tools for the project.
CE 3.2.3 My area of work
I was responsible for the preparation of the NCOs if required. I had to read and reply on
the site instructions received from the consultant. I was responsible for preparing the AS-BUILT
drawings and following up the SNAGGING LIST for the project final handing over. I was also
responsible for preparing all the documents which required for the final handing over of The
project like Operation & maintenance manuals. I had also supervised all Electrical installations,
Testing and commissioning and design for a pumping stations.

CE 3.2.5 My responsibilities throughout the project
I had worked with my team to provide the client with the best quality work for the
project. I had conducted studies of The Technical Offers of Tenders. I was in charge of revising
the tender drawings and calculations taking into concern the voltage drop. I had prepared the
Shop Drawings. I had also helped in the preparation of the prequalification and material
submittal for all electrical work. At the end I had handed over the work to the consult authority
that supervises on the project.
CE 3.3 Distinctive Activity
CE 3.3.1 Comprehending the theory of the project
The project is based on the development of a 6 kilometers road starting from intersection
of Abu Bakr Al-Siddiq Road with Thumama Road up to the King Salman Road. The project had
been launched by Arriyadh Development Authority. I was responsible for looking after the
necessary communications devices like traffic lights, CCTV cameras, lighting, electric and
power systems. Due to some problems I had worked on diverting the existing service networks
from the main project work. I had also helped in the implementation of the service networks
compatible with the road's new levels and design.
CE 3.3.2 Engineering knowledge and skills applied in the project
For the completion of the project I had coordinated with the Government authorities for
the clearing of site related problems. I had then reviewed the lux calculation for indoor lighting,
outdoor and road lighting. I then revised the tender drawings and calculations of the project. I
had then provided supervision on electrical work as the technical specifications and followed up

the work plan. This helped me to prepare the prequalification and material submittal for all
electrical work.
CE 3.3.3 Accomplishment and task performed
I had worked on the project for the development of 6 kilometres road. I had helped in the
following of the quality of the process of the reviews and the installation inspection for the
project timeline. I had assisted my team in the review of the shop drawings and for the ensuring
of the design was being followed as planned. I was asked to acct the material engineer and thus I
was responsible for looking after the quality of the material s that was being used for the project.
I was also asked to meet with the local authorities for the process of submittals of the contracts
and other necessary site visits. At the end I had acknowledged the risk assessment of the project
and the safety of the project site and of the workers.
CE 3.3.4 Identified issues and their solutions
3.3.4.1 Issues
Once the lighting system of the King Salman Road had been completed, I found that the
MCCB was tripping many times. This caused the whole lighting circuit to cut off. I then checked
the electronic time of the panel and the photo cell conditions which showed no tampering
problems. Then I noticed that the Earth Leakage Circuit Breaker (ELCB) had also been tripped.
This ELCB had been calibrated on a 2MA scale. Thus this was the reason for the tripping of the
lighting circuit.
Another problem which I had faced during my work on the project was after the
installation of the Ultrasonic level sensor (LST500) for the pumping station in Anas Ben Malik. I

found that the sensor was showing fluctuations in the reading for the water level in the tanks.
This problem indirectly affected the functionality working of the pump.
3.3.4.2 Solutions
I increased the calibration of ELCB from 2 MA to 15 MA. After this I switched both the
ELCM and the MCCB on at the same time and the circuit panel was working correctly.
After the analysis of the problem I found that the control cable and the wires for LST500
was pulled in the same cable tray of the power cable. This problem caused the generation of a
magnetic field which forced the sensor to have noise in the values of the readings and thus the
wrong readings. This caused me to consult with the ABB Application Engineer. I then decided to
isolate both the control cables and wires from the power cable instead of using the same tray.
This solved the problem and the sensor was showing correct readings.
CE 3.3.5 Plan to produce creative and innovative work
For the project I had implemented my knowledge of the electrical development and
provided with the most creative work of my career. I studied that the lighting fixtures that I was
provided with to install for this project was based on High Pressure Sodium (HPS) type. I had a
meeting with the client and discussed with them the problems which could arise with the
installation of the HPS lightings. I suggested to them to use LED lightings instead of the HPS. I
described to the clients the advantages for the use of LED lights which had virtually zero
maintenance cost and the working time of the LED lights are more than the standard found
lights. This made them to change their decision and asked me to proceed with the installation
procedure of the LED lightings. During the installation of the lights there was found to be a clash
between the lighting pole in the centre median and the pedestrian bridge. This forced me to

cancel the installation pf the lighting pole and instead install a LED Light projector of 200W
which provided the desired LUX projection in the area.
CE 3.3.6 Collaborative work
I had taken the help from my team members and my supervisor to complete the project
and to deliver to the client the best quality work. The complete project was under the ownership
of Arriyadh Development Authority. I was working under the contract of Ferrovial Agroman
Company. For the lighting fixtures installation, after the client decided to install LED instead of
HPS I had contacted Phillips to provide with the lighting fixtures for the complete project. I had
then worked with them to find the best LUX which would cover the entire area of the project.
CE 3.4 Project Review
CE 3.4.1 Project Overview
I was able to provide the client with the best quality project and the most innovative and
creative one of my career so far. I was able to perform specifications and data sheets for
electrical equipment for the complete project. I had conducted regular factory inspection and
testing of electrical equipment to keep up with the working of the project. I had also conducted
technical bid evaluation. I also had good knowledge of overall engineering workflow and project
schedule development that helped to complete the project in the given timeline and within the
availability of resources.
CE 3.4.2 My contribution to work
I had worked as the senior electrical engineer of the project which made most of the hard
work to fall on my shoulders. This proved to be a challenge and made to gain experience in the

field work. I had to coordinate with the Government authorities like SECECO(Saudi Electric
Compnay , STC(Saudi Telecom Company) , Ministry of Transport, General Administration of
operation and maintenance to solve site problems. I had to coordinate with the civil and the
mechanical engineers to provide the client with the best quality work. I had provided my
supervision on electrical work based on the technical specifications and follow up the work plan.
I had also made a plan for the technicians, workers and equipment to execute the electrical
works. I had conducted studies of the drawings of project, reading contracts and BOQ tables and
specification.
