The most comprehensive and accurate cost coverage for all construction

Vista, CA – July 23, 2020 – BNi Building News, a Design Cost Data Company, has just released the 31st annual edition of the BNi General Construction Costbook. The completely updated 2021 edition includes a new section providing construction costs by assembly type, represented by major categories designated by UNIFORMAT.

The 2021 BNi General Construction Costbook breaks costs down into material, labor and equipment, to allow for maximum flexibility and accuracy in estimating. Readers will find the data invaluable when preparing detailed estimates, bids, checking prices, and calculating the impact of change orders. 

All data is categorized according to the CSI format. This industry standard provides an all-inclusive checklist to ensure that no element of a project is overlooked. In addition, to make specific items even easier to locate, there is a complete alphabetical index. 

“We are excited about the launch of the new 2021 General Construction Costbook,” states BNi President Bill Mahoney. “Our focus is to help builders bid more aggressively for new jobs while maintaining their profit margins. Our General Construction Costbook makes this possible by providing them with the most accurate data available.  At the same time, we are making construction estimating much easier!”
