2003 February The Qinshan CANDU Project represents the latest design of its class, with much improved safety and power output. 12
2003 February 4. SCHEDULES The heart of the Qinshan planning and scheduling management was a detailed 8500-activity Level 2 (Project Co-ordination and Control [C&C] schedule), which set the work requirements for all major project activities, including Engineering deliverables (identified as Release for Construction – RFC), Procurement (identified as Delivery Requirements), Construction and Turnovers, and Commissioning. These Level 2 C&C schedules were produced within 6 months of CED. The Level 3 schedules were developed by engineering and supply organizations within the first 12 months of the Project. The construction and commissioning Level 3 schedules were developed throughout the first two years. The individual subcontractors produced their own Level 2 and 3 schedules to comply with the overall Level 2 C&C schedule. The Level 2 C&C schedule was formally revised three times over the life of the Project to reflect actual progress and incorporate improved sequences for construction and commissioning. A major challenge of working was to introduce and then successfully implement Level 3 planning. AECL, with TQNPC support, provided training and hands-on teaching to the construction contractors to produce Level 3 schedules that were integrated among the contractors and that matched the activities in the Level 2 C&C schedule. AECL, Bechtel and CNPM produced detail Level 2 and 3 schedules for engineering and supply schedules by area, using 3D CADDS, Primavera scheduling system and an integrated Qinshan Deliverable System that detailed deliverables along with the budget, resources, schedule, status and responsible people. By the end of the job, a database containing more than 50000 activities had been produced by the contractors for the Construction Level 3 schedule. Monthly updates by the engineering, supply, construction and commissioning groups were provided in order to update the Level 2 C&C. The output was analyzed, and the critical path and variance analysis were produced. A separate monthly scheduling report, including the corrective actions taken when required, was issued to all Project participants. 13
