Founded in 1897 and family owned and managed for over
75 years, Kraus-Anderson Construction is consistently
ranked by Engineering News Record among the Midwest’s
Top 20 Construction Firms. An integrated development,
construction, and real estate leasing and management firm
with national project experience, Kraus-Anderson offers
an owner’s perspective while collaborating with clients,
architects, and stakeholders to ensure project success.
“KA looks differently at subcontractor criteria than an architect,” he explains. “As an architect, I was taught to focus on end results and not to specify means and methods. As a contractor, it’s all about the means and methods. There is a risk profile difference between the two, but that lends itself well to labor and subcontractor certification programs. A third-party evaluation is a plus.”
A subcontractor’s financial strength is paramount to KA’s hiring decisions. A strong safety record comes a close second. NACC certification mandates documentation for both, meaning certified subcontractors are prepared to meet the stringent requirements of a large GC such as KA.
Since launching in July 2015, NACC has gained industry acceptance and recognition for raising the bar of quality and professionalism. Yet there are still areas of the country without certified subcontractors. Spence, who expects the program to grow, suggests specifying qualifications and documentation in alignment with NACC certification in cases where specifying a certified contractor is not possible.
Specifying Curtain Wall
To assist the A/E and subcontracting communities, the KA Building Science Group developed the presentation, “Curtain Walls from the Contractor’s Perspective.” The presentation provides design teams with insight and understanding of curtain wall performance requirements and best practices perspective regarding curtain wall specification, detailing, and testing. According to Spence, “By understanding the contractor’s perspective, you will be better prepared to eliminate waste in your design and documentation process by focusing on what’s important for the owner and contractor.”
The presentation explains how potential risks can be reduced by specifying end results rather than means and methods and suggests architects and engineers, “consider NACC and AGMT criteria as a starting point.” He outlines key factors that should form the basis for qualifying glazing subcontractors: business practices, safety programs, quality programs, administrative procedures, and operational procedures. Not coincidentally, all of these criteria are documented as part of NACC certification.
Level of Detail
According to Spence, the level of detail encouraged by NACC is an asset to the certified subcontractors and the design and construction community. Since curtain wall manufacturers rarely approve or endorse subcontractors, independent third-party verification provides a safeguard. From structured quality and safety programs and documented procedures for shop fabrication to field deliveries and on-site applications, the protocols documented during certification keep questions to a minimum and instill confidence in the hiring GC.
Spence says that KA encourages its design community partners to focus on defining performance criteria: how the finished application must perform and not necessarily how to get there. This has been a recurring theme in his education presentations. “The value in NACC certification is that in the procedural guide for NACC are those criteria. Certified contractors provide predictable performance. That’s really important.”
