DCAMM Contractor Certification for Massachusetts Public Building Work
DCAMM contractor certification is required when any Massachusetts public agency — the awarding authority — solicits bids for a vertical construction project with an estimated construction cost of at least $150,000 under M.G.L. Chapter 149 or 149A. That covers construction, reconstruction, demolition, maintenance, or repair of a building. If the project fits that description, plan for certification before the bid deadline, not after.
Who needs DCAMM certification
Contractors bidding as prime bidders to Massachusetts public awarding authorities on covered vertical (building) projects. The threshold test is the estimated construction cost: at least $150,000, under M.G.L. c. 149 or c. 149A, for construction, reconstruction, demolition, maintenance, or repair of a building. ProcurAlerts is an independent service, not affiliated with DCAMM or the Commonwealth — confirm the requirement in the current solicitation and with the awarding authority.
How certification works
DCAMM certification is category-specific: you are certified in the categories of work for which you qualify, and bids must match the categories the solicitation requires. Certification is renewed annually, so an expired certificate is effectively no certificate at bid time.
What DCAMM certification is not
- It is not MassDOT highway prequalification — highway construction bidding runs through MassDOT’s separate prequalification program
- It is not a trade license or a Construction Supervisor License, which are individual licensing requirements that may also apply
- It is not COMMBUYS vendor registration, which creates your vendor record and notification settings but certifies nothing
- It is not a small-business or diversity certification, which are eligibility programs run by other offices
Common failure points
- Treating a COMMBUYS account or vendor number as evidence of construction certification
- Bidding a category of work outside your certified categories
- Discovering at bid time that the annual renewal has lapsed
- Assuming DCAMM certification covers MassDOT highway work — or that MassDOT prequalification covers vertical building work
- Overlooking the $150,000 estimated-cost trigger because the firm self-performs only part of the scope
Action checklist
- Identify whether the project is vertical construction under c. 149 or c. 149A with an estimated cost of $150,000 or more
- Confirm your certification covers the categories of work the solicitation names
- Verify the certification is current and calendar the annual renewal
- For highway work, check MassDOT prequalification instead
- Keep licensing and vendor-registration obligations tracked as separate items
