By now, I hope you know me well enough to know that I’d never, ever say you should make a guaranty of performance, period, let alone guaranty the green performance for a new building. However, sometimes caution has to be thrown to the wind to get the job– at least in the case of a recent GSA design-build project in Seattle.
There, the design-build team agreed that the GSA could withhold 0.5% of the original contract amount, or $330,000, pending the achievement of energy goals. As writer Suzanne H. Harness, J.D., AIA, noted recently:
The GSA’s approach is diametrically opposed to the recommendations of the American Institute of Architects, which advises both architects and contractors not to guarantee or warrant the achievement of a sustainability goal. The AIA’s 2011 Sustainability Guide explains the obvious: contractors and architects can design and construct a building, but the owner operates it, and the owner’s actions are beyond the control of the design and construction team. If the owner operates the building differently from the assumptions used during design, performance goals will likely not be met, even if the building is perfectly constructed. [Emphasis added].
Ms. Harness also correctly noted that professional liability insurance would not cover such a guarantee of performance. So beware to the design team who takes such a project on: they can be held contractually liable, but there will not be insurance to cushion the fall out from any lawsuit.
Just DON’T do it!
