Construction projects can be simple, short term tasks or complex, multi-year endeavors involving millions of dollars. In major projects, numerous outside contractors (and subcontractors) are often hired, even if the overall project is awarded to a large well-known engineering or construction firm. Unless the project is insured in a Wrap Up program (all contractors, subs and subs of subs are insured under one contract for one job), then management cannot presume that all of their contractors are insured continuously through the period of the project.
