1. PURPOSE

This document describes the methods proposed to be used for the installation of temporary fence that will be carried out as part of ASU Construction Works of Qatar Shell GTL Plant (Pearl) in Ras Laffan Industrial City of Qatar including the works in the TSF Area.

2. SCOPE

The fence components will be transported to site on trucks and will be offloaded near the area. This document covers the installation of delivered components to form a temporary fence.

The fence will be installed in Gama TSF Area as per the attached layout (Please see Attachment)

3. HSSE

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

All personnel will go through Gama, Linde and Company Safety Induction courses as well as other trainings as identified by their supervisor. Please see Document Number GTL-GM-001-A-5635 for details.

A Job Safety Analysis (JSA) specific for this work including a Risk Assessment, is prepared as per Gama procedure GTL-GM-001-A-5626 and is attached herein. Such JSA addresses the hazards associated with each task within the scope of this Method Statement and introduces the controls that will be implemented to reduce the associated risks to acceptable levels. The JSA will be used by the Site Supervisor as the basis of his TSTI / TSTO and Toolbox Talks.

All personnel will have PPE required for their specific tasks in addition to the minimum PPE (coveralls, safety goggles, safety shoes, high-visibility vests, gloves) at site at all times as required.

In the event of a release, fire or explosion, employees will secure their area and evacuate to the nearest muster point. Once all employees are evacuated the supervisor will conduct a headcount to verify all employees are out of harms way. The supervision will report this to Contractor. Emergency Contact numbers for Company, Contractor and Gama will be posted onsite.

All vehicles and equipment used for the subject work will be inspected and certified as required.

Drivers and operators will be competent and will have attended all required trainings set forth in project procedures and specifications.

8. METHOD OF EXECUTION

8.1. PRE-COMMENCEMENT WORKS

Existing Underground Facilities

Prior to work commencement, the existing and possible underground structures and installations will be checked by means of As-Built Drawings issued by the Contractor or the Company. The locations of such installations will be marked at site and posted with signs. After the area has been barricaded, possible relocation or removal applications for the same will be studied. Same studies will 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 will be informed immediately; and approval of Contractor and Company will be waited before proceeding with the relocation or removal of the same. The barricades for such activities will be temporary.

Access Roads

The locations of access roads within the execution area will be pointed out by the Contractor. These access roads will be used for the planning of concrete activities within the area. However, 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. Nevertheless, no such diversion will take place without prior written consent of the Contractor or the Company. After the locations of access roads have been excavated, they will be backfilled to allow traffic in and within the area.

Barricades, Safety Signboards & Night Activities

All work areas will be barricaded and posted with signs before any work starts. Barricades will be formed by black pipes (steel); and the signboards will be placed as needed. Barricades will be kept in place until the work done and the areas have been filled.

Since no night activities are foreseen for the time being, the site will be kept closed during the night preventing any pedestrian or vehicle traffic. The requirement for illumination will be reviewed by Contractor, when this condition is expected to change due to other works or a change in the work schedule. Or by the time, night-work activities are foreseen, the site will be illuminated for workers to execute relevant works. Order of Precedence

In case of any conflict with this document and Project Specification “Roads, Paving, Surfacing, Slope Protection and Fencing (DEP 34.13.20.31-Gen)” and all its Amendments and/or Supplements, the latter (Project Specification) will prevail.

8.2. INSTALLATION OF FENCE AND GATE

Surveying and Mark-Up Corners of the area or end point of the line to be fenced will be determined and marked by the usage of existing monuments. Between marked corner points or end points, fence line, gates and terminal post will be located with stakes not exceeding 152 m distance or line of sight between each other. After determining fence line alignment within 12 mm tolerance, footings locations will be marked for excavation and further progress. Distance not exceeding 3 m between two adjacent line post, and 1 intermediate pull post at every 150 m (max.) interval will be the criteria for marking, except for gate locations.

Foundation Works and Installation Excavation for foundation will be performed according to footing dimensions which are tabulated in Table-1 below.

Table 1 – MINIMUM FOOTING DIMENSIONS

Post Description Depth (mm) Diameter (mm)Line Posts 1000 300 Corner/End post 1250 450 Pull posts 1250 450 Gate posts for gate leaf up to 1.5 m width 1250 450 Gate posts for gate leaf between 1.5 m and 3.0 m 1500 600 Gate posts for gate leaf between 3.0 m and 5.0 m width 1500 700

Depth of excavation will be modified in order to provide proper vertical alignment. All debris and water will be removed from the excavation and, plain concrete, of which mix and construction will be in accordance with the project specifications DEP 34.19.20.31-Gen and T-13.376.358 (See references) will be poured. In case of excavation of granular soil, mold will be provided. Post will be supported preventing misalignment during pouring of concrete.

Access to the post will be prevented by soft barricades in order to prevent misalignment up to setting of concrete.

The depth will be measured from finished grade to bottom of concrete. The bottom of concrete will be at least 100 mm below the bottom of the line post and 150 mm below the bottom of the corner/end post, pull post and gate post.

Footings will be cylindrical in shape with a top of concrete being 100 mm above finished grade as measured at the post and sloping away from the post with at least a 12 mm drop.

After erection of posts and setting of concrete, fence and gate fabric barbed wires, tension wires, top rail, stretcher bars, braces, extension arms and gate hardware will be installed in accordance with the approved drawings. Both sides of fence will be cleared and graded for a distance of 600 mm at each side of fence line in order to remove or fill irregularities causing clearance more than 50mm below the bottom of the fence and gate. Openings such as drainage areas, culverts or troughs will be closed by barriers, or as approved by the Contractor, without preventing the water flow.

Any work described herein will be carried out as per the relevant Method Statement.
