About Building Systems Design
BSD develops the best master specification content available to the architecture, engineering, and construction markets of North America, and delivers that content via innovative software tools that help you simplify your projects and get more done.
We were founded in 1983 to develop commercial software for the Federal government. We did this for more than 15 years, and some of our software is still used by the Army Corps of Engineers and the Department of Defense for detailed construction cost estimating.
Our suite of products still includes CostLink/AE, which helps architects, engineers, and other non-financial-experts produce cost estimates. We also produce master guide specifications for use with our SpecLink-E system, and interoperability with BIM and Revit through our LinkMan-E product. And because software is only as valuable as its implementation, we offer extensive support as well as a full range of training options to meet the needs of both the novice and advanced user.
BSD was acquired in 2010 by the Construction Specifications Institute, an industry organization with the mission of advancing building information management and the education of project teams to improve facility performance.
