Understanding the Benefits of Cost-Based Estimation

This white paper discusses the cost-based estimation methodology and its benefits in construction project bidding. It outlines how reliable estimates can enhance the evaluation of bids, leading to more informed future estimating practices. The document details the five key elements that contribute to a cost-based estimate: materials, labor, equipment, production, and profit. It emphasizes the importance of understanding the construction process to create accurate estimates, which can stand up to bid prices. Additionally, it compares cost-based estimation with other methodologies, such as bid-based and ad hoc estimation, highlighting the pros and cons of each. The paper also addresses the significance of using estimates to evaluate bids effectively and discusses the concept of unbalanced bids, which can distort the true cost of work. By fostering discussions with contractors, agencies can gain insights into their estimating practices, ultimately leading to better project cost management.
