The project should prepare a comprehensive risk assessment prior to CD-2. A contingency analysis should be completed based on identified project risks. A Monte Carlo analyses methodology should be used to evaluate the adequacy of the contingency. The 3-meter rock overburden on the Ash River building has a cost impact of $6-7 million on the cost of the facility. This should be evaluated in more detail to determine if a more cost effective alternative could be found. The proposed building conceptual design meets the technical performance requirements to enable installation and operation of the NOνA detector. The project CDR and supporting documents justify the proposed cost range and project duration. 3.3 Recommendation 1. Recommend approval of CD-1. 20
4. COST ESTIMATE 4.1 Findings The cost estimate for the NOνA construction project was developed using a comprehensive task oriented WBS summarized below: Table 4-1. NOνA Work Breakdown Structure WBS 2.1 WBS 2.2 WBS 2.3 WBS 2.4 WBS 2.5 WBS 2.6 WBS 2.7 WBS 2.8 WBS 2.9 WBS 2.10 Far Detector Site and Building Liquid Scintillator Wave-Length Shifting Fiber PVC Extrusions PVC Modules Electronics Modules Data Acquisition Strategy Near Detector Assembly Far Detector Assembly Project Management Included in the project’s Total Project Cost (TPC) was WBS 1.X, R&D and Project Engineering and Design (PED) estimates. The project team presented a TPC range between $197-256 million (actual year [AY]) for the NOνA project. The best estimate was $247 million (AY), which includes 35 percent (approximately $64 million) contingency. The project’s cost and schedule estimates were presented down to WBS Level 5 in most areas, with some areas to Level 8. Quotations and other pricing were compiled to establish a base cost in FY 2006 budget. The Project <strong>Off</strong>ice will centrally manage the project controls software (Open Plan and COBRA). A summary of the NOνA preliminary estimate of project costs is shown in Table 4-2. 21
