// LESSONS FROM Soublière-Trinity Partnership
Winning a government-program anchor contract early provides stable volume that funds growth into riskier commercial work.
EP 56 · Dwaine MacDonald
Over-reliance on a single government program is a political risk; deliberately diversify revenue streams before the next election cycle.
EP 56 · Dwaine MacDonald
A senior GC mentor who trusts you with jobs and teaches you the commercial ropes compresses years of learning you cannot replicate alone.
EP 56 · Dwaine MacDonald
Rapid revenue growth without matching profit is a trap; 700% growth in a year may leave nothing on the bottom line.
EP 56 · Dwaine MacDonald
When entering a new city, plan to hire locally within six to twelve months or travel costs will permanently price you out of smaller jobs.
EP 56 · Dwaine MacDonald
Bundling multiple interior-envelope scopes under one subcontract reduces GC coordination overhead and improves schedule predictability for both parties.
