BNI Mechanical Electrical Costbook 2025

All of the data is organized according to the industry standard the CSI MASTERFORMAT so you can find everything you need fast. What's more, Geographic Modifiers allow you to tailor your estimates to specific areas of the country. Every cost item has been carefully researched and updated.

The mechanical and electrical portions of a building typically account for 30% or more of construction costs. This type of work is very specialized and includes materials and installations which require detailed pricing -- such as piping, valves, ducts, fans, chillers, condensers, conduit, and transformers. All of these areas are thoroughly covered in this costbook.

Over 14,000 unit prices are broken down into material and labor costs, and complete man-hour tables provide maximum coverage and flexibility.

All data in the Costbook pages and Man-Hour tables is organized according to the CSI MASTERFORMAT - the industry standard numbering/classification system. The data is divided into the 16 divisions as shown below. The five digit numbers within each division correspond to the MASTERFORMAT Broadscope designations.

Each section is further broken down into MASTERFORMAT Mediumscope designations. These numbers, in most cases, are the same as those used in architectural and engineering specifications.

The construction estimating information in this book is divided into two main sections: Costbook Pages and Man-Hour Tables. Each is organized to the 16 divisions of the CSI MASTERFORMAT as shown below. In addition, there are extensive Construction Reference Tables, Geographic Cost Modifiers, Square Foot Tables and a detailed Index.

Sample pages with graphic explanations are included before the Costbook pages, Man-Hour Tables and Square Foot Tables. These explanations, along with the discussions below, will provide a good understanding of what is included in this book and how it can best be used for construction estimating.
