Cost Model Formulation for Estimating Architect - Engineer Fees at Base-Level Civil Engineering

摘要

The purpose of this thesis was to statistically analyze a base-level data base of Architect-Engineer (A-E) contracts to demonstrate the possibility of cost model formulation to predict or estimate A-E Fees. The models were based on the 'cartooning' estimating technique for developing fee estimates based on the expected number of drawings required in the final A-E design. Analysis of variance was used to separate project characteristics which affected the per drawing cost. Utility work, number of disciplines, community facilities, and total number of drawings affected the per drawing cost. Simple and multiple linear regression were used to derive cost models for predicting A-E fees on future projects. Four cost models were developed. Only one cost model using number of drawings was judged successful based on the statistical criteria. However the technique of cost model formulation for estimating A-E fees was demonstrated.
