A nine-building city block in a Nordic capital: 276 apartments, one framework contract for the complete building envelope — windows, doors, sealing, insulation, subsystems, rainscreen cladding, flashings. Handovers sequenced building by building over almost five years, through five sub-Arctic winters.
The contract was signed months before the sharpest construction-inflation cycle in decades. A five-year fixed-price envelope programme should have ended in claims, disputes and renegotiation — that is what happened on comparable sites across the market.
Treat price governance as part of the delivery system, not the commercial aftermath. Unit prices were fixed per building at the start of each envelope and revised only through the national statistics wage index — a mechanism agreed once, at signature, and never argued about again.
The same crews rotated across the block in sequence, compressing the learning curve building after building. Extra works were captured as dated, itemised batches at contract rates, in the same workbook the owner certified monthly. Owner QC ran on a shared digital platform with contractually embedded weekly meetings.
Nine buildings handed over in sequence, final progress application certified June 2026. Five years of inflation absorbed contractually: zero claim disputes recorded across the entire programme.
- Long programmes don’t fail on price — they fail on how price changes are governed. Fix the mechanism at signature, not the numbers.
- Crew continuity across repeat structures is a compounding asset: the last buildings cost less to deliver than the first, in the same contract.
Inflation breaks programmes through disputes, not prices. Index discipline is governance, not accounting.
