Engineering Costs and Fees for Municipal Wastewater Treatment Works -An Estimating Technique for Design of Treatment Plants.

摘要

An analysis of costs and manpower efforts expended to design wastewater treatment works was conducted by the Construction Grants staff of the Environmental Protection Agency,Region 6. The purpose of the study was to establish a mutual basis for estimating/evaluating manpower requirements and reasonable engineering fees for EPA projects. Agency personnel collected actual manpower and financial resources expended on designing specific wastewater treatment works projects. This data,adjusted for inflation and other cost fluctuation,provided an empirical basis for statistical comparison with other parameters. The relationships developed provide a methodology for estimating and analyzing engineering fees for wastewater treatment plant design. The study's essence is a nomograph and related table that can determine the median number of drawings required and corresponding A&E design costs/manhours.
