Construction quantity change scenario engine

Accelerate cost-informed design discussions

Confirm the buyer's problem and scope, collect professional-approved quantities and supplier quotes, then follow this sequence: 1. Map confirmed design variants. 2. Recalculate comparable cost scenarios. 3. Flag unpriced scope. Resolve uncertain cases with qualified reviewers, approve surveyor-reviewed option cost comparison, and measure estimator hours saved and accepted scope savings minus review cost against a documented baseline.

How the AI works

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. No autonomous quantity certification or procurement commitments. A model suggestion is never a verified fact, professional decision or authorization to act.

Safeguards

Verify property facts and scope assumptions. Clearly label visual alterations. Professional reviewers retain responsibility for contracts, engineering and legal interpretations. No autonomous quantity certification or procurement commitments. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.

What to build first

Pilot scope: No autonomous quantity certification or procurement commitments. Implement one approved input format, a bounded representative case set and the first two task modules: map confirmed design variants; recalculate comparable cost scenarios. Support the third module with operator review: flag unpriced scope. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.

What it can connect to

Property records, construction documents, project photos and supplier quotes. Read-only operational exports, calendars and finance or inventory records as relevant. Start with plan exports and retain human approval for execution. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.

The screens in detail

Primary screens: Constraint and input setup, Scenario comparison, Decision and pilot tracker. Place editable drivers and constraints beside a clearly labeled scenario output. Include a baseline view, comparison chart or schedule, and an assumptions history. Let users trace a proposed quantity or date back to its inputs. Keep forecasts distinct from actual results. Make the task-specific outcome surveyor-reviewed option cost comparison visible beside its evidence, review state and value baseline.
