King County WTD – Generator Installation Projects at the Denny Way Regulator Station Facility and the Lakeland Hills Pump Station
This project provides engineering services to perform two WTD projects that both involve installing standby power generators at existing facilities: the Denny Way Regulator Station Facility and the Lakeland Hills Pump Station. The objective of the combined project is to provide permanent standby power generation at two facilities, the Denny Way Regulator Station Facility and at the Lakeland Hills Pump Station.
P&M prepared construction cost estimates & schedules in accordance with the King County WTD Estimating & Schedule Guidelines during alternative design and final design phases. P&M documented all assumptions used in cost estimates and reasons for cost changes between each level of design.
1. Prepare class 4, 3, 2 and 1 opinion of probable construction cost for each design submittal
2. Prepare draft Life Cycle Cost Analysis (LCCA)
3. Provide a Basis of Estimate (BoE) with each estimate documenting cost assumptions and reasons for cost changes from the previous estimates.
