Design Information Memorandum No. 12


1.0 PURPOSE

The purpose of this Design Information Memorandum (DIM) is to present the preliminary engineer’s construction cost estimate for the primary treatment design project at the City of Sunnyvale’s Water Pollution Control Plant (WPCP). Please refer to the individual technical memoranda (TMs) included in the preliminary design report for detailed descriptions of the recommended project elements.

2.0 BASIS OF COST ESTIMATE

The preliminary engineer’s construction cost estimate is representative of a 10-percent level design cost estimate. The estimated construction costs presented in this DIM are based on preliminary layouts and preliminary unit sizes as developed in DIM Nos. 1 through 11. Other construction elements that may not be described in the DIMs but are required for the project, such as sitework, yard piping, yard structures, etc., are also included in the cost estimate.

The estimated construction costs were developed from preliminary quantity takeoffs, estimating guides, equipment manufacturers’ quotes, and construction costs of similar facilities at other locations. An estimating contingency of 25 percent is applied to the estimated construction costs to compensate for lack of design details known at this stage, uncertainties in bidding climate, and assumptions used in the estimating methods. A local sales tax of 8.75 percent is included for approximately half the estimated construction costs. A 10 percent factor is applied to the estimate to cover the contractor’s cost to meet the General Conditions of the specifications, including mobilization, demobilization, bonds, insurance, and field overhead. A 13 percent factor is applied to the estimate to cover the general contractor’s home office overhead and profit on the project.

Engineering, legal, and administration costs, as well as construction contingencies for contract change orders, are not included in the estimated construction costs.

While the estimated construction costs represent the average bidding conditions for this project, variations in bidding climate at the time that the facilities are constructed could affect actual construction costs. Furthermore, the size and character of the facilities will be refined during final design based on the most current operational information, evolving design concepts, and plant staff input. For these reasons, it is possible that the actual construction costs may be lower or higher than estimated.

An overall annual cost escalation of 3 percent per year was used to account for cost escalation to the mid-point of construction. For planning purposes, it is anticipated the


project will be constructed in three packages. Table 12.1 summarizes the assumed construction start date, construction duration, and mid-point of construction date for each package.
