Installation: own crew or supervision
Two models, one geometry check, and the labour mathematics behind each.
Full crew
Fastest and most predictable for complex houses: our team erects, aligns and commissions. Cost is higher per day, schedule risk is lower.
Supervision model
One or two supervisors with your labour. Cheaper on paper, but it depends on the local team's skill and on the materials arriving in sequence.
The geometry check
Gutter line, column plumb, bay square and roof line. Errors here propagate into glass breakage and vent binding two months later.
Commissioning is not a walkthrough
Run the systems for a full day, log the set points, test alarms and hand over the as-built set. A house is commissioned when the data says so.
