Basis of Estimate Clause Samples

Basis of Estimate. The Offeror shall provide a basis of estimate in excel spreadsheet format for each task discussed to include but not limited to team size and make up, number of teams, labor productivity/ duration, labor hours, labor categories, subcontractors, number of meetings, etc., such that the evaluators can get a clear understanding of the basis for the proposed approach. The list of equipment and materials shall be itemized in the basis of estimate to reflect the work proposed for the sample task order. The key subcontractor BOE shall not be a lump sum and shall be detailed to include team size and make up, number of teams, labor productivity/ duration, labor hours, labor categories, equipment, materials. To assist with a crosswalk for the technical and price evaluators, Offerors shall provide corresponding basis of estimate page number in the Technical Approach – Volume I, Tab 1, Element 2 to corresponding basis of estimate page number in the Price – Volume III, Tab 4. The Sample Task Order will be used for evaluation purposes only. The Sample Task Order will not be awarded.

Basis of Estimate. The cost estimate is based on the closure plans outlined in Sections B.1 to B.4. Generally if there is uncertainty in the work scope, a conservative position has been adopted (more expensive) in preparing the estimate such that further refinements in closure planning may result in lower rather than higher cost. Quantities were partly provided by LMC, while some were newly developed from “as built” drawings. A library of structural drawings showing details of buildings and facilities was prepared and studied in detail to help define the extent of closure and demolition. The primary cost estimator has been working on site for over a year and is familiar with local operators, contractor capability, logistical constraints and productivity. Labour and other costs were assumed to be current Lihir contract award rates. Equipment costs were current Lihir operating or contractor hire costs. No significant permanent new materials are required for closure so no costs were obtained from suppliers. Lihir Management Company Limited December 31, 2004 Lihir Gold Mine — Mine Closure Plan Update 2004 It is assumed as normal in the mining industry, that work will be initially carried out by LMC staff with some hire of local equipment and contractors/consultants as required. As closure proceeds, more contractors will be used and LMC staff involvement will reduce.

Basis of Estimate. Table 3 presents estimated fuel usage during construction and commissioning activities at yards and the planned duration of activities. Jacket Construction 73 22 24 Topside Construction 157 14 48 Subsea Infrastructure Construction 7 2 15 Notes: Based on average monthly recorded data from fuel consumption within the BOS SHELF and ATA yards during 2011 and 2012 for COP. A review of fuel consumption data from the Bos Shelf yard for the ACG Phase 3 project indicated 55% of diesel use was for engines and 45% for generators. This assumption has been maintained Emissions estimates were based on the duration of operation and approximate fuel consumption associated with equipment that will be commissioned onshore which is assumed to include the main generator run for one week consuming 8 tonnes of diesel per hour for 8 hour per day and intermittently over approximately 6 months, two air compressors (assumed
