Due Diligence Services
The scope of transactional due diligence continues to expand and change, and Calex Environmental tracks these changes via American Standards and Testing Materials (ASTM) Standards E1527, E1528 and E1903 to provide standard-of-care information to the parties of commercial and industrial real estate transactions. ESAs satisfy one of the qualifications (“All Appropriate Inquiry”) for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on Superfund liability.
