When it comes to construction of any kind, due diligence is an important matter. The list below isn't exhaustive but does represent the minimum due diligence for construction.
- First and foremost, verifying that the construction company is in a solid financial position is essential. The financial failure of a contractor or key supplier can be catastrophic to a project.
- Validation of all certifications and licenses or permits necessary to do the work
- Business continuity and disaster planning and test results
- Listing of subcontractors and resources used to secure labor.
- Third-party risk management processes, including evidence of due diligence and monitoring
- Evidence to demonstrate that suppliers of electrical equipment and components prove the products they provide are genuine and meet safety requirements
- Listing of equipment owned vs. equipment to be leased or subcontracted
- Proof of insurance
- Litigation, claims, or other legal disputes- including any judgments
- List of workers' compensation claims
- Disclosure of any past or current safety violations or hazards
