Engineering construction cost estimates are developed to attain accurate cost assessments for total project as well as construction costs. Construction cost estimates ensure project costs are within the authorized dollar amount. It also presents a comparison of costs on previously constructed facilities.
This document supplements the Architect-Engineer conditions by analyzing the Items, Units, Unit Price, Quantity Divisions, Cost Divisions, Total Quantity and Total Cost that contribute in the generating project budgets and construction cost estimates. Items included in the sheet are 30° Pipe, 30° DI Pipe, Large diameter Manhole, WT F&C, Standard F&C, 42" Steel Casing, 4" Lateral, 6" Cleanout, Pavement Replacement and various others.
The creation of such cost estimate sheets helps in compiling a record of historical costs and establishes the "design to cost" limits for the Architect/Engineer (A/E). Besides it provides a means of cost control during design.
