"We wanted to make sure that everyone involved agreed that the plan we had in mind was the best way to approach to project." Everyone consulted agreed that Kieferle's plan was a good one. With all necessary permits granted, Kieferle began final planning for what he called "a very challenging proj ect." The combination of the wide open building and the incredible con centrations of asbestos presented numerous challenges to Kieferle's team not usually found in smaller projects. The first step in the removal pro cess was to break the building down into zones--the building was just too large and too contaminated to at Tons ctf asbestos were carefully bagged and sealed for disposal by the Insulation tempt cleaning all at once.
