Pipe Hanger Installation

Prepare delivery schedule and check site conditions as well as storage capacity. Prior to delivery of Material to site, conduct a site survey and make all necessary co-ordination with the main contractor as regards to access for the save transportation of the said material to the designated location. Coordinate with site workers responsible for the system installation.

Incoming Inspection and Storage

• Check model and type of material against delivery order.
• Check any damage during transportation.
• If there is any evidence of damage, an internal inspection shall be made together with supplier’s representative and the consultant. A report shall be submitted to the Consultant on completion of such inspection.
• Route identification and marking work shall not be started until coordinates with other Mechanical and Electrical Services.
• Minor deviation from the approved construction drawing and M&E drawing would be determined on site with the consent of consultant site staff.

Fire Protection Riser Pipe Installation Method

1) Check Location of Riser

• Confirm the location of riser based on approved / coordinated shop drawings.
• Check whether any opening through slabs (either box-up or pipe sleeves) is provided.
• Check the size of the opening. If the opening size is not sufficient or opening is not provided, request permission for coring from the Main Contractor.
• Core opening once approval is obtained.

2) Fabrication of Pipe

Fabricate pipes

3) Hoisting of Pipe

• Book the Materials Hoist or Tower Crane fro hoisting the pipes to the designated floors.
• Position the pipes at the area allocated by the Main Contractor.

4) Install Riser Pipe

• Confirm the location of riser based on approved / coordinated shop drawings.
• Lower down the pipe off any unwanted materials and rubbish from the riser shaft.
• If box opening is provided, slip a piece of pipe sleeve onto the pipe.
• Coupled the pipe with previously installed pipe with a flexible coupling. (Please refer to Method Statement for the installation method of flexible coupling).
• Pull upwards the newly installed pipe using the chain block. This is to allow pipe movement during the building shrinkage.
• Align the pipe vertically with spirit level.

5) Install Riser Pipe Bracket

• Once the pipe has been aligned, install the pipe bracket to support the riser pipe.
• If box opening is provided, install temporary bracket to the pipe.
• Cast the opening and ensure the pipe sleeves are installed prior to casting.
• Once the concrete has cured, dismantled the temporary bracket and replace it with a permanent bracket.

6) Install Fire Barrier

Install Rock Wool into the gap between the riser pipe and the pipe sleeve as per contract requirement. The Rock Wool will act as fire barrier in the case of fire.
