CONSTRUCTION AI ASSISTANT LIMITED

What CONSTRUCTION AI ASSISTANT LIMITED does

Construction AI Assistant Limited is a UK private limited company founded in 2025 that operates ConstructionAssistant.AI, a fully self-serve product-led platform selling individually-licensed custom-built GPTs to UK construction professionals. The company targets Quantity Surveyors, Project Managers, Estimators, Contract Managers, Site Managers, and Building Surveyors with role-specific AI assistants pre-loaded with UK construction standards (JCT Design & Build 2016, NEC3 ECC, NEC4 ECC, CDM 2015, RICS standards, NRM1/NRM2, BCIS, Building Safety Act). Each GPT is configured with role-specific terminology, workflows, and template libraries and is delivered as a unique, periodically rotating secure ChatGPT access link to prevent license sharing.

The product portfolio consists of 179 GPTs spanning Core, Specialist, and Leadership tiers; 13 are live and available for purchase, while 166 remain in active development. The platform is built entirely on OpenAI's ChatGPT infrastructure, with ConstructionAssistant.AI acting as an independent prompt-engineering layer rather than a foundation-model provider. Distribution is exclusively direct-to-customer via the company website using Stripe-powered checkout, with no sales team, channel partners, or paid advertising channels. The technology includes document upload and analysis, photo-based defect identification (SurveyorPro AI), voice command site documentation (Construct IQ), and multimodal workflows across the portfolio.

The revenue model is a one-time 12-month license per GPT at £99 for standard products and £149 for leadership-tier products (Contract Manager Pro, Commercial Manager Pro), with no auto-renewal, no subscription bundles, and bulk team licenses available on request. The company is bootstrapped and self-funded through product sales, with no disclosed external venture capital, headcount, or revenue. Customer acquisition relies on content marketing through an Insights blog, free prompt packs and guides, and SEO targeting UK construction-specific search terms.

Comparable as a major incumbent with overlapping AI ambitions for construction QS, PM, and surveying roles, but operating at a much wider portfolio level.

Emerging players

• Disperse: UK construction AI startup applying AI to analyse site data and project performance. Comparable as a UK-based vertical AI player in construction with a focus on operational intelligence, though narrower in scope than the company's 179-GPT catalogue.
• LetsBuild: Construction project management and field collaboration platform with AI-driven progress tracking. Comparable as a software vendor for UK/EU construction PMs and site managers, overlapping with the company's Construct IQ and Project Manager Pro GPTs, though as a broader platform rather than specialist AI.
