New Hampshire's construction sector includes more than 50 registered companies in our database, ranging from general contractors and specialty trades to heavy civil and commercial builders. Construction companies carry elevated compliance risk: OSHA 29 CFR 1926 governs fall protection, scaffolding, excavation, and electrical safety, and violations can result in six-figure civil penalties. Before hiring a New Hampshire construction company, verify their OSHA inspection history and confirm they are not listed on the SAM.gov exclusion database — especially if your project involves federal funding. Approximately 42% of listed NH construction companies have at least one documented risk flag.

Frequently Asked Questions — Construction Vendor Screening in New Hampshire
How do I screen a construction company in New Hampshire before signing a contract?
Run three parallel checks: (1) search the SAM.gov exclusion database; (2) review OSHA inspection history for safety violations and penalties; (3) if the vendor operates commercial vehicles, check FMCSA safety ratings. KnowVendor aggregates all three into a single free report. The top OSHA citations in construction are fall protection (29 CFR 1926.501), scaffolding (1926.451), and hazard communication (1910.1200). A pattern of willful or repeat citations significantly raises vendor risk.
What compliance risks are specific to construction vendors in New Hampshire?
The top OSHA citations in construction are fall protection (29 CFR 1926.501), scaffolding (1926.451), and hazard communication (1910.1200). A pattern of willful or repeat citations significantly raises vendor risk.
Can an OSHA violation disqualify a construction company from federal contracts?
Not automatically, but a pattern of serious or willful violations can lead to SAM.gov suspension or debarment, which bars a company from federal contracts. Always check both OSHA history and SAM.gov exclusion status together.
What is the SAM.gov exclusion list and who does it affect in New Hampshire?
The SAM.gov exclusion database lists entities prohibited from receiving federal contracts or assistance. This includes companies that have been debarred for fraud, defaulted on federal contracts, or violated federal regulations. In New Hampshire, construction companies working on government-funded projects or serving as subcontractors to federal primes must not appear on this list. KnowVendor checks the database daily.
