2003 February 9. METHOD TO SUBCONTRACT MATERIAL AND CONSTRUCTION WORKS The Chinese construction contractors were responsible for providing skilled resources, management and supervision, planning of work and quality program. Site Project Management Organization (SPMO) provided overall management of NSP construction and technical assistance to the construction contractors to reinforce their planning, develop Level 3 schedules, develop catch-up programs, schedules and plans, develop and use production indicators to manage bulk works, assist contractors in subcontracting specialized activities such as structural steel design and fabrication, improve organization of contractors for better communications and increased productivity, develop quality procedures, assess training programs and update as needed, assist contractors in complying with worker qualifications and certificates, assist contractors in setting up and executing check and test programs that represented an increase in their traditional scope, and assist and monitor the contractors in the setting up and carrying out industrial safety and worker safety programs. The Project construction scope was divided into a series of Construction Work Packages (CWPs). Individual general works subcontracts were established for mass excavation, pipe prefabrication, ready mix concrete production, temporary construction utilities, and inland transportation. The plant building and system CWPs were established by craft disciplines and compiled into two civil and two installation subcontracts, one each for the Nuclear Steam Plant (NSP) and the Balance of Plant (BOP). AECL entered into the subcontracts covering the general works and the NSP civil and installation works with local contractors selected with the agreement of TQNPC. TQNPC entered into subcontracts for the BOP. The subcontractors priced the works on a CWP basis, which permitted firm prices to be established for a large percentage of the scope. Other works where only preliminary information was available were based on fixed unit prices and provisional sums for the different commodities. AECL and Bechtel/Hitachi supplied the majority of the material and equipment separately, with the exception of mainly concrete, rebars and steel. Since each subcontract firm pricing was established at a low level breakdown within each CWP, the subcontractor-estimated labour resources were more accurately established and available. Interrelationship with the construction schedule was readily available and produced accurate labour and cost monitoring and forecasts throughout the implementation of the construction works. Quantity reconciliation between contract value and actual quantity installed was regularly kept up-to-date and contract values were adjusted accordingly. Contractors were paid based on the actual quantity installed. Figure 9-1 shows the Site construction interface. 27
