Package baselines are rounded to £0.1M. The explicit −£0.1M reconciliation brings their £249.6M sum to the model’s £249.5M central estimate. Tender totals are unchanged. Opportunity range = tender less the upper and lower expected cost bounds.

Unitised curtain wall pricing is the main commercial review priority. The package is £4.7M above its £31.4M benchmark.
INDICATIVE PACKAGE EXPOSURE£4.7M
RECOMMENDED ACTION
Request the contractor rate build-up, reconcile quantities and obtain alternative supplier pricing.

04 / Assumptions & verification gaps
- Same package scope and cost basis assumed; exclusions, quantities and specification still require professional reconciliation.
- 19,000 m² and £1,900/m² are demo tender inputs. Benchmark unit rate is derived from the package benchmark, not an independent observed market rate.
- Central London, premium residential high-rise; location, scale, height, specification and cost-date adjustments are represented in the demo model, not independently verified observations.
- The 18 comparables and confidence designation shown elsewhere are illustrative. No individual comparable records or licensed source dataset are connected.
- Variance is a review opportunity, not a confirmed overcharge or guaranteed saving. Findings overlap the project opportunity range and must not be added to it.

£249.5M is the model central estimate, not the arithmetic midpoint of the £246M – £254M interval (£250M). “18 comparables” and confidence are demonstration values, not claims about buildvoro’s current dataset.
Benchmark basis — product vision
Client history and tender intelligence combined with external indices and project-specific adjustments. This selector explains the intended approach; it does not recalculate the fixed demo.
Every benchmark can be adjusted for location, asset type, scale, height, specification and cost date in the intended model.
Comparable-project intelligence
Illustrative matching records — not real customer projects.
Strong match on location, asset type, height and façade; basement scope needs adjustment.
Matching percentages demonstrate the future interface. No matching engine is running here.
Published context, transparent assumptions.
The illustrative benchmark was supplied for this demonstration. Published industry commentary informs its cost-context explanation; it does not independently validate these project totals.
RLB · London Construction Market Intelligence · Q2 2026Region: London. Metric context: tender price growth, capacity and construction cost pressures. No proprietary global database or licensed dataset is claimed.
06 / INTELLIGENCE, WITH EVIDENCE
