McKennyKrug, Inc. was established in 1991 by David McKenny and Douglas Krug as an engineering partnership with a focus on structural engineering and building code applications. We began life as MBAK Code Design (MBAK being an acronym of several meanings…); the "code design" moniker reflects the integrated relationship between building code applications and building design.

Our name changed from MBAK to McKennyKrug to more accurately reflect the people involved with the work – it’s who we are - and to exit the acronym-laden world of engineering companies. McKennyKrug serves clients ranging from small jurisdictions to large municipalities, and works closely with a select group of leading designers and builders in structural design applications.


David McKenny and Douglas Krug are the managers and principal engineers of McKennyKrug, Inc., Structural and Civil Engineers. Both are licensed California Structural and Civil Engineers as well as International Code Council certified plans examiners; our plan review certification dates back to the 1985 edition of the Uniform Building Code. You can click on our names for a more extensive background of each partner, and maybe a picture or two if we can keep the lens from cracking.
