How to Avoid Costly Errors Bidding
As leader of a company which has specialized in developing building construction estimating methods and resources which have been relied upon by generations of Construction professionals
and educators for over 103 years. I would like to offer a succinct summary of error prevention steps which have proven value in the process.
Accurate estimating is the “life blood” of successful construction estimating. Frequently, estimators have limited experiential cost data for aspects of
the job and seek expert industry sources of exploratory or confirming data, for portions of the estimate or confirmation of accuracy of sub-contractor’s bids. Therefore it is vital for building cost estimators to select authoritative proven sources when referencing
construction estimating books, data sources of building construction, labor productivity, material quantities and unit costs. For more information refer to:
which differs from typical pricing books as variable cost components are developed considering the effect of method details influencing unit costs.
The most common cause for errors is failure to identify all of the variables of construction labor and material costs in the take-off process. Many pricing
books do not detail these factors, so is important to reference source materials which do. We offer over 1400 pages of Excel ® formatted unit prices, tables, templates and charts combined with reference material and

Estimating errors which occur while compiling the data can be minimized by using efficient estimating forms and software spreadsheets for accurate quantity take-offs, extensions and

control tools for project managers to price change orders, manage purchasing and are vitally important in prevention and settling claims disputes. The estimate and supporting documents live far beyond the bidding process and play an important role throughout
the life of the project affecting its successful and profitable conclusion.
