Just as a land developer may hire a general contractor to oversee a variety of subcontractors who actually perform the construction work, a commercial investor often hires an inspector whose responsibilities typically involve overseeing a variety of subcontractors. These subcontractors provide specialty inspection reports on building systems, such as HVAC, electrical, roofing, structure, and whatever else is called for in the client/ inspector contract. 

This inspection will ensure the building is in the proper condition it should be to protect the investor.
