ICAST can perform your General Property Needs Assessment in full compliance with federal and any other requirements. We assess immediate critical repair needs, expected repairs, and replacements as well as other needs to operate and maintain your building for years to come. This assessment provides solutions for how your building can perform more efficiently in the future and ranks items relative to return on investment. 

Sustainable technology reduces waste and saves money.

ICAST projects implement sustainable technology to improve the efficiency of energy and water systems. These devices pay for themselves through utility bills savings.
