Mobilization Plan
Transportation on Site
The booster/circulation pump sets shall be transported and delivered to the sites as per the delivery schedule. The unloading of equipment will be using the resident mobile crane or tower crane or manpower (should condition permit) at the designated platform in coordination with other trade and cranes will be operated by the authorized licensed operator under project safety rules and regulations.
Storage
If pump sets are to be stored for later installation, care must be taken to protect the pump sets by proper stacking in the site store to protect them from damages.
Inspection of Equipment in Stores
Material Inspection Request (MIR) should be released and all materials delivered should not be used unless it has been inspected by the consultant and verified for conformance to specification.
Programmed Reference
The work program for the installation of pipe works would be as per the latest MEP Master Work Program.
Installation of Pump set
System Description
- Each packaged Booster pump set system (2 pumps – 1 duty and 1 standby) comes complete with a pressure vessel provided.
- The Packaged Circulation Pump set system comes only as two individual pumps with identical specifications and related useful details.
- The pumps are factory assembled onto a common base plate together with a factory assembled control panel.
- Gate valves, check valves, pressure gauges, butterfly valves, etc. are factory assembled and connection at the site is only to the suction and discharge header.
- The complete system is factory tested before delivery to the site. The control for the booster pumps (start/stop) is done by pressure switches.
- There is also a low-level float switch to prevent the dry run. Booster Pumps are operated in a lead-lag manner to rotate between two pumps to balance the operation hours.
Preparation Work
- Before the start of installation, the following are required to be carried out.
- Make sure that the site/building is ready for installation of the pumping system and unloading platform, equipment access hatch is provided before the material delivery.
- Make sure that the shop drawings have been approved by the consultant and the drawings have been coordinated with other services.
- The delivered pump sets shall be as per specification and ensure that all materials delivered are undamaged and protected.
- Ensure all the materials have been inspected and approved at the site as per the relevant Material Inspection Request form.
- Check the RC pump plinth and ensure that the dimension and location of the pump plinth are according to requirements.
- Inspect and carefully check that the top surface of the booster pump plinth is level.
- Inspect & Check carefully that the work area is clean & tidy
Installation of Water Pump Set
- Locate the booster pump set system onto the booster pump plinth.
- Adjust the orientation of the pump set system so that the suction and discharge header outlets are correct and in line with the suction and discharge pipe connection.
- Highlight and mark the position of the screw hole at the mounting base on the pump plinth.
- Remove the booster pump set and drill holes on the booster pump plinth based on the markings.
- Insert the drop-in anchor into the hole.
- Insert an anti-vibration neoprene pad at the bottom of the pump set system base frame to isolate any vibration from being transferred to the building structure. (If required)
- Adjust the booster pump set system to make sure it is appropriately level.
- Connect the suction and discharge pipes to the pump set system suction and discharge header connections.
Measure and Plan for Safety and Health
Personnel engaged with this work shall follow a safety and health Plan; Safety & Health Manager will nominate one safety officer to check and monitor safety and health plan implementation.
Emergency Procedures
