Berrien County retained ECT to provide comprehensive engineering specifications and designs, construction management, and related environmental services associated with the $2 million demolition of a four-story, 250 bed hospital complex, originally built between 1907 and 1939.
Featuring four sets of interior stairwells, five passenger elevators, two 1,000-HP boilers and a 100-foot-tall chimney, ECT conducted a hazardous materials survey and pre-demolition inspection of the facility in order to compile information relevant to the preparation of engineering specifications designed to raze the structure and abate the existing physical/environmental hazards in a manner that would facilitate redevelopment of the site in accordance with the objectives of the local unit of government.
ECT personnel identified, inventoried and quantified observed asbestos containing materials (ACMs), lead-based paint (LBP), and all suspected hazardous and universal wastes associated with the building that would require abatement or special handling prior to, or during, demolition.
In the development of contractor specifications, ECT used a combination of lump sum and unit rate bid items to base compensation for those items where quantities were not readily discernible. During the client’s procurement of demolition trade contractors, this process reduced the need for contingency monies in the contractors’ bids, and was ultimately credited for having reduced total project costs by more than 10 percent.
ECT was responsible for providing overall site control and oversight of all trade contractor activities, including documentation of site activities, assuring the proper handling of materials, and avoiding the commingling of disparate waste materials. Because the site was located within a largely residential district and surrounded by single-family homes, all site work necessitated strict adherence to issues involving air monitoring and dust control.
