Prior to the commencement of any of the activities, the workforce will receive an induction talk on the project site safety requirements. This induction talk will include both the activity particular safety issues as well as the general project safety requirements. ESHO will enforce the project safety requirements. Heat stress training will be provided. Provisions of adequate cool drinking water, shade, and salt water tablets will be in place.

8. Prior Activities:

8.1	Prepare and get approval of office layout drawings
8.2	After approval of the layout drawings, checking requests for site activities are submitted to the engineer to follow the work in the site.

9. Procedure:

All activities carried out will comply with the OAJ-JV Inspection Test Plan which reflects the testing requirements of the Contract.

Construction of the site offices will be properly coordinated with the approved programme of works.

9.1 Roof Sandwich Panels

9.11	Before erecting the roof sandwich panels, the columns and the roof trusses are checked for plumb and compliance with approved drawings.
9.12	A crane is used to lift the sandwich panels (11.05m length x 1.00m wide x 50mm thick) to the top of the roof, by using belts.
9.13	The ends of the sandwich panels, centred over the roof trusses, are screwed in place with 5” long hexagonal screws – by using self screw drilling machine.
9.14	A minimum of 4 screws are used at each line of purlins.
9.15	After fixing the hexagonal screws, the top of the screw will be capped.

9.2 Wall Sandwich Panels

9.21	A horizontal galvanised iron track, to receive the wall panels, is fixed to the floor between the column posts.
9.22	The wall sandwich panels, measuring 1.00m wide x 50mm thick x 3.025m high are erected one by one, starting from one end. The first panel is held in place by screwing it to the column, with 5” long hexagonal head screws. Each vertical wall panel is locked with the other by “tongue and groove” joint.
9.23	After all the panels are erected in place, a horizontal galvanized iron track is placed on the top of the panels, and after the wall is checked for plumb, the track is welded at its ends to the column posts.
9.24	A minimum of 4 screws are used for each panel.
9.25	After fixing the hexagonal screws, the top of the screw will be capped.

10. Responsibilities:

10.1	It is the Contractor’s Site Manager’s duty to ensure that all necessary safety and protective equipment are provided along with properly trained and qualified personnel.

10.2	It is the Site Supervisor’s duty to organize the work in a safe manner to ensure that safety and protective equipment are being properly utilized. He must also assure the method statement procedure is followed and must observe the hold-points and notify the Consultant for inspection.

10.3	It is the worker’s duty to properly wear the protective equipment provided and obey all safety rules. He must also perform the work as described in the method statement procedure.
10.4	The Contract Manager will coordinate with Safety Engineer and ensure that the necessary resources to implement the approved method statement have been allocated to the task.
10.5	The Site Engineer will ensure that the site preparation activities are conducted according to the approved method statement.
10.6	The Material Engineer will ensure that the materials being used are in accordance to the project specifications and the approved method statement.
