Preliminary

Survey and set out to establish and mark the exact location of the wall panel to be installed in accordance with the approved shop drawing.

Pre-work control measures identified in the attached Risk Assessment shall be in place.

Pre-construction meeting to discuss the execution of this procedure involved and may include the presence of the Engineer.

Determine specification requirements method of work execution and relay this to the site foreman.

Responsible for cutting the slab or wall.

Site clearance is to be provided as required.

Site Planning & Preparation

Site layout and identification of works area must be done prior to work execution.

Coordination with the Site engineer, QA/QC engineer, HSE officer shall be observed.

All the works shall be carried out confirming the approval of shop drawings and HSE policies.

Installation of the cold room shall comply with and meet the requirements as per site conditions.

Work Methodology

Testing and Commissioning of Fire Suppression Systems Methodology

1) Preparation

The following interfacing should be available and done:

All related cabling work, fire alarm, and electrical interfacing.

Fixing of mechanical gas shut-off valve into the gas pipeline.

Completed civil works.

2) Pre-commissioning

Carefully inspect the nozzles for any physical damage.

Check and ensure that the nozzles directly point to the cooking equipment.

Check the tightness of all nuts/bolts, screws, fasteners, etc. as applicable.

Check piping connection as per approved drawings.

3) Commissioning (Testing & commissioning using spare cartridge & empty tank known as “Balloon Test”)

a. Testing of manual pull station and building fire alarm interface testing with volt free contact micro switch. Remove the brake rod & pull the manual pull station (the cartridge is separated from the mechanism). The cartridge pin will come out from the release mechanism and the alarm begins.

b. Testing of detection line and distribution line by balloon test (using empty agent tank and cartridge.) By replacing the test link in place of the fusible link from the detector line, put balloons on all nozzles, and break the test link (put the system in active condition). Cartridge pin will come out from the release mechanism, the system begins to release the gas (CO2) through the nozzles at the same time alarm begins and the balloons get inflated with the gas.

c. After the above testing, the system has to be recharged and reset again to set the system in active condition.

Quality Control

Inspection & Testing

Inspection and Testing shall be performed in accordance with Inspection and Testing Program (ITP).

The necessary inspection as stated in the work procedures shall be carried out.

The QC Engineer and Site Engineer will check and monitor the progress of execution of work to ensure that the work process complies with this procedure.

Upon completion of every stage of work, a joint quality inspection between the contractor’s QC Engineer/Site Engineer and Consultant shall be carried out to check the quality of work.

Any unsatisfactory workmanship or defects found shall be rectified and preventive action shall be taken to prevent the occurrence of the same for subsequent works.

Systems Manual

The Systems Manual must be submitted electronically or on paper and must include the following principal sections:

System descriptions

a. Title sheet including the project’s full name, address, and phone number the installing contractor’s name and address, along with a phone number service for emergencies)

b. The entire contents page

c. Documentation of the system design intent

d. A comprehensive list of the tools

e. A list of manufacturers and/or suppliers of equipment

f. Major component operation and maintenance guidelines
