Who's Watching the Watchers?

General Interest The International Building Code (IBC), the basis for the California Building Code and most local building codes throughout the U.S., requires special inspections for critical structural components of new construction. Welding, high-strength bolts, precast concrete members, and steel reinforcing in concrete are examples of components that must be inspected, verified or monitored by special inspectors.
The International Building Code Commentary, published by the International Code Council, explains these requirements as follows:
Special inspections provide a means of quality assurance. Structural properties of the concrete or steel that is used in most structures are not usually discernible by a mere visual inspection. Typically, construction materials must be tested and their installation must be monitored in order to provide a finished structure that performs in accordance with the construction documents. Trained specialists that provide these inspections give the building official and the engineer an indication that the required structural performance will be achieved.
Furthermore, Section 1704.1 of the IBC states:
The special inspector shall be a qualified person who shall demonstrate competence, to the satisfaction of the building official, for inspection of the particular type of construction or operation requiring special inspection.
In New York City yesterday, Testwell Laboratories, a testing company, and V. Reddy Kancharla, Testwell's owner, were convicted of filing fraudulent test reports during the construction of several high-profile projects in New York.
In its original complaint, the New York County District Attorney's Office had alleged that Testwell engaged in numerous schemes that involved falsifying inspection records. In one of these schemes, "The Compressive Strength Scheme", the D.A. claimed that Testwell "systematically falsified" concrete strength tests:
For example, in connection with the construction of the Freedom Tower, TESTWELL was hired by the developer to assure that the concrete met the design specifications of 12,000 PSI. From May 2006 until September 2006, TESTWELL certified that the concrete reached or exceeded 12,000 PSI on each and every occasion tested. However, in late September 2006, the Port Authority commenced its own testing and determined that the concrete was averaging around 10,000 PSI and that only a third of the pours ever hardened to the required 12,000 PSI. The Port Authority then did core testing, removing samples of the concrete that were already in place, and found that it was actually 9,000 PSI—not the 12,000 that TESTWELL had certified.
Owners, architects, engineers, building officials, as well as the ultimate users of the built environment, must be able to rely on the competence, integrity, and independence of third-party inspectors. It appears that sometimes someone needs to watch over those that are supposed to be watching over the safety of our buildings.
