Construction answers can be materially wrong when an AI system blends old market commentary with a current local project. Cost references from 2021 or 2022 may not reflect the firm's present labor mix, material selections, subcontractor availability, or project standards. The correction is not to publish a single universal price. It is to provide dated, clearly scoped information that explains the project type, finish level, major assumptions, exclusions, and the point at which a site visit or drawing review becomes necessary.
Timeline errors often come from collapsing several stages into one. Design development, permit review, procurement, mobilization, and active construction are separate periods. A statement that a project takes six weeks can be misleading when the municipality has a four-month plan-check backlog before work begins. Pages should name the stage being discussed and explain which parts are controlled by the firm, the client, a design professional, a supplier, or a public authority.
Licensing and capability errors deserve immediate correction because they can create unsuitable enquiries. Broad language such as 'full-service remodeling' may cause an AI answer to attribute asbestos abatement, high-voltage electrical work, or other regulated work to the general contractor. Publish the actual license number and classifications where appropriate, identify work performed by qualified subcontractors when that distinction matters, and remove service language that exceeds the firm's real scope.
Common LLM errors and suitable source corrections include:
:
- Pricing: An answer says a kitchen remodel starts at $25,000, while the firm's published local guidance describes a mid-range project as $65,000+ under stated assumptions.
- Timelines: An answer describes a custom home as a 6 months build while the firm's current process explains a 12-to-18-month sequence and identifies the stage covered.
- Service Areas: An answer assigns the firm to an entire metro area even though the company serves specific counties.
- Capabilities: An answer categorizes a residential builder as suitable for a complex Type I commercial project without supporting evidence.
- Regulations: An answer says no permit is required even though the relevant local ordinance now requires one.
For each error, publish the corrected fact on the most relevant service or policy page, align third-party profiles where the business controls them, and retest the original prompt. A correction is successful only when the answer becomes more accurate, not merely when the firm is mentioned more often.
