CU02 Construction Tender is one of TIAA MRT Project's underground constructions which included civil engineering, electrical systems & water services (E&W) construction and environmental control construction and covers three stations: Airport Terminal 1 Station (A12), Airport Terminal 2 Station (A13) and Airport Hotel Station (A14a). The E&W construction and environmental control construction in each station should be under monitor and control by the building management system (BMS), details are as below:
1.Electrical systems & water services (E&W) construction: includes fire prevention, fire alarm, water supply and drainage, main L.V. switchboard, floodgate and fire escape doors, tunnel lighting, restroom emergency alert system, access control, etc.
2.Environmental control construction: includes ventilation (including winding machines, wind doors, tunnel ventilating systems, etc) and air conditioning system (including chilling system, temperature/humidity sensor, etc).
The integration tests of E&W and environmental control construction of CU02 Tender and BMS includes the following:
1.Prior to integration tests, the contractor should raise the testing proposal in the engineering interface coordination meeting for thorough discussion with involving constructors to ensure that the integration testing proposal conforms to regulation. Then, the proposal is required to be submitted to the supervising consultant for examination and ratification.
2.The testing proposal should consist of scheduled testing time, duration, arrangement of workforce, interface position testing items, measuring tools (including communication equipment), test standards, etc. Such details should be consistent to BMS-control equipment.
3.Position testing of pre-operation equipments should also be performed in this integration test prior to equipment operation. After confirmation from both parties, operational tests of equipment can then be performed. During equipment operation, relevant signals will be transmitted to BMS to achieve monitoring and control function of the system.
The CU02 Tender and BMS Integration Test is a significant job prior to official operation of the TIAA MRT Project. Currently, each station has finished the integration test. From this integration, the main equipment in each station can receive supervision and control from SCADA in the Operational Control Center via BMS transmission. Subsequent to the integration test, pre-operational tests will be implemented.
