Our View

Every square foot is a financial asset. Space accounting is the discipline that connects measurement to revenue. This is the philosophy behind everything we do.

History

From a Manhattan Beach basement in 1985 to the authority in commercial building measurement worldwide. Four decades of precision, standards authorship, and client trust.

Peter Stevenson

Founder, BOMA Fellow, and the person who defined space accounting as a financial discipline. Peter has measured more commercial buildings than anyone in the industry.
