AXA South does not self-perform licensed trade work and does not represent itself as a licensee of any trade or profession.

AXA South is a contracting and program-management firm, not a licensed trade.
The market, honestly.
New Hampshire pulls federal demand from Portsmouth Naval Shipyard and Pease. State civilian spending out of Concord rounds out a small but stable buying base.
Precision manufacturing, defense electronics, submarine overhaul work tied to Portsmouth Naval Shipyard, and a tourism and outdoor-recreation economy in the north.
For hvac, electrical & plumbing specifically in New Hampshire, our model is direct: AXA South responds to the solicitation, holds the contract, and runs the program. Local crews and licensed trade partners in New Hampshire perform the work that requires their license or specialized credentials.
Portsmouth Naval Shipyard performs submarine overhauls on multi-year availabilities, which makes it a milestone-driven subcontract and supply market. State purchasing under the Department of Administrative Services is compact and centralized.
State fiscal year ends June 30. Shipyard availability schedules, not the fiscal year, set the rhythm for the state's largest federal work. The federal fiscal year closes September 30, so August and September carry the heaviest volume of simplified-acquisition and micro-purchase activity at every installation in the state.
New Hampshire does not operate a state minority set-aside program. NHDOT administers the federal DBE program, and federal socioeconomic categories apply on federally funded contracts.
Approaching the shipyard as a prime market. Most accessible work there flows through established overhaul contractors, and supplier qualification precedes any quote.
