Lea by LeanAIOS

Lea by LeanAIOS is an AI system that positions itself as a virtual construction team. Its website lists 18 distinct areas of construction management that the AI covers, from estimation to handover. The service claims to act like an experienced specialist in each field, catching problems before work reaches the site.

In practice, the tool expects construction drawings, contract documents, and project schedules as inputs. For example, the Estimate and Bid module takes the bid line items you upload and cross‑checks each unit price and market rate against a database that the site says it sources from. The output is a report that lists the original bid figure, the referenced market rate, and a note if the bid appears unusually low. The Contract feature monitors the dates in the subcontractor agreements. If a subcontractor's notice period extends beyond your own deadline to the client, the system alerts you on that day, prompting a note in the daily report. Project Setup measures quantities by parsing construction drawings, then juxtaposes those figures with the contract quantities and shows the source for each data point. In Design, the assistant scans the drawings you provide for signs that a crew may be working from an older revision; it flags the discrepancy before formwork is erected. The Finance module calculates price escalation when an extension of time occurs, aligning the new program with payment applications and supplying a revised measurement for each line item.

Lea targets project managers, general contractors, and subcontractors who need a coordinated view of their documents and timelines. The free pilot offers 100 credits, allowing up to five separate project simulations with unlimited users, so a small office can test the system without creating an account. Larger firms might select the Growth, Professional, or Enterprise credit plans, which each share a common pool of credits for all team members and are valid for one year. The system does not detail any integration with existing ERP or BIM platforms, nor does it list specific file formats it accepts beyond the general mention of drawings and contracts.

The tool includes a built‑in approval matrix. Every change or new draft is routed to the relevant role and, if that role is absent, to their deputy.
