The package advantage is continuity. The same lead carpenter who sets out the frame is still on-site for the second-fix door hanging. That's how defects stay low, and how small details at lock-up get carried through to finish without getting lost.
Single director across the scope. One point of accountability from quote through to defects close-out — not a relay race between a PM, a site supervisor, and a finish coordinator.
Program-aligned resourcing. Crew ramps up and down with the program — full frame crew at structural, smaller finish crew at second-fix — without changing out the lead on the job.
Priced properly. Itemised quote with clear first-fix, lock-up and second-fix splits. Assumptions and exclusions written out so there's no surprise at variation time.
