AI for Construction
Construction digitises more slowly than other sectors, and its problems are countable: budgets overrun by 20-50% and dates that move. AI reads BIM and CAD documentation, forecasts delay from weather and logistics data, and produces cost estimates without weeks of manual work. Contractors and developers who have adopted it cut cost variance by 30% and build time by 15%. The entry point is documentation in digital form - on projects run off scans and spreadsheets, the first phase is putting the data in order, not building a model.
Three uses of AI in Construction
Automated estimating and document analysis
The system reads CAD and BIM drawings and technical specifications, extracts quantities and builds an estimate on current material and labour prices. Ambiguities and contradictions in the documentation are flagged before anyone breaks ground.
Site safety monitoring with computer vision
Site cameras wired to an AI model catch safety breaches as they happen: no hard hat, work at height without protection, entry into an exclusion zone. The system alerts the site manager and logs the event with a photograph, which builds a compliance record.
Delay prediction and schedule optimisation
An ML model sets live project data - progress, weather, crew availability, material deliveries - against the history of previous builds and calculates delay risk at each stage. It proposes schedule corrections and resource moves before a delay reaches the critical path.

What makes it hard
Low digitisation - many contractors still work off paper documentation and spreadsheets, which makes data collection hard
Every site is different, so ML models transfer poorly between projects
Site conditions - dust, vibration, changing light and weather all work against cameras and sensors
A conservative industry - management prefers methods that have already been proved
Frequently asked questions
Can AI really predict delay on a site?
Yes. The model reads hundreds of variables - weather, material availability, crew productivity, subcontractors - and forecasts risk at 75-85% accuracy. It does not predict black swans, but it catches patterns an experienced site manager can miss on a complex project.
What does AI site safety monitoring cost?
A system with four to eight cameras and the model, for a typical site, is €7,000-14,000 to deploy and €700-1,200 a month for cloud and model updates. The cameras move between sites. One serious accident avoided repays it many times over.
Can it work with BIM documentation?
Yes. The system reads IFC files - the BIM standard - and analyses geometry, materials and the relationships between elements. From that it produces quantities, flags clashes between services and estimates cost. Revit, ArchiCAD and Allplan connect through the standard formats.

AI for E-commerce
AI in an online store usually starts in three places: product copy, customer questions and pricing.
AI for Logistics
In logistics AI goes where the scale is: routes, stock levels and shipping paperwork.
AI for Real estate
In property, AI does three things: it values, it matches listings to buyers, and it writes the listings.
