1. INTRODUCTION

1.1. GENERAL

This document describes the methods of activities for the establishment of permanent benchmarks that shall be carried out in Ras Laffan Industrial City of the State of Qatar for Pearl GTL Project.

1.2. SCOPE

Establishment of Permanent Benchmark Facilities shall take place on the dedicated place(s) as per approved layout area. The construction & erection activities shall be carried out by Gama Qatar.

2. HSSE

All works shall be in compliance with the State of Qatar laws and regulations, Ras Laffan Industrial City and International standards, codes, Contractor and Company requirements and instructions.

In addition all employees and GAMA Subcontractor employees on site will have through Contractor Site Safety Induction and GAMA Qatar Safety induction for site safety, health, environmental and security prior to work activities. Other training courses will be attended as required by Contractor or Company as required.

At a minimum a generic Risk Assessment will have been prepared by the Risk Assessment Team (RAT) ranking the hazards associated with project works and control measures to be taken to mitigate the hazards to an acceptable level.

Each work scope or task will have a completed and approved Job Safety Analysis (JSA) identifying the potential hazards and control measures that will be implemented to protect people and environment.

The JSA will be used by Supervisor as the basis of conducting his daily Pre-Task meeting and his weekly Tool Box Talk (TBT).

In addition to the above, all employees will wear required PPE and highly visible vest where traffic or other hazards may exist. For additional safety instructions and precautions please review the JSA completed for Establishment of Benchmark facilities.

5. METHOD OF EXECUTION

5.1. PRE-COMMENCEMENT WORKS

5.1.1. Work Permit

All facilities shall be executed with the required permit to work. After receiving the related permit, the execution will take place in the scope of job requirements.

5.1.2. Traffic Management Plan

Works shall not interrupt any kind of vehicle traffic or any access roads to any gates. In case of this kind of activity a revised traffic management plan shall be provided.

5.1.3. Equipment and Personnel

All equipment shall be inspected and approved by the CONTRACTOR, and all personnel shall be inducted and trained before mobilization.

5.1.4. Existing Underground Facilities

Prior to work commencement, the existing and possible underground structures and installations shall be checked by means of As-Built Drawings issued by the Contractor or the Company. The locations of such installations shall be marked at site and posted with signs. After the area has been barricaded, possible relocation or removal applications for the same shall be studied. Same studies shall be submitted to the Contractor and the Company for approval. Should any underground facility be encountered in spite that they have not been pointed out in the drawings, Contractor shall be informed immediately; and approval of Contractor and Company shall be waited before proceeding with the relocation or removal of the same. The barricades for such activities shall be temporary.

5.1.5. Access Road

The access roads may be diverted for some periods during the execution of the works in order to ensure smooth execution of the works in the area. However, no such diversion shall take place without prior written consent of the Contractor or the Company. After the locations of access roads have been excavated, they shall be backfilled to allow traffic in and within the area.

All work areas shall be barricaded and posted with signs before roadworks. Barricades shall be formed by scaffolding pipes, and shall be subject to Contractor and Company approval before being put to use; and the signboards shall be placed hundred meter intervals. Barricades shall be kept in place until the cooling water pipes have installed and the area have been filled. Since no night activities are foreseen, the site shall be kept closed during the night preventing any pedestrian or vehicle traffic. The requirement for illumination shall be reviewed by Contractor, when this condition is expected to change due to other works or a change in the work schedule.

5.2. EQUIPMENT & MANPOWER

5.2.1. Equipment

- Concrete Mixer Truck

- Excavator

- Steel Pins

- Barricades

- Formwork

- Shovels

5.3. METHOD OF EXECUTION

5.3.1. General

The benchmarks shall be constructed according to the existing benchmarks in adequate frequency. To ensure the required stability, the benchmarks shall be constructed with reinforced concrete. To specify the coordinates of the benchmarks, angular and dimensional values shall be obtained by using total stations and implementing closed traverse method. Besides, in order to specify and determine the levels, Automatic Levels shall be used as stated in the Method Statement for Surveying Works (T-4.234.067). The proposed location of the benchmarks is presented in Attachment 2.

5.3.2. Excavation
