Construction

One site, one source of truth, from drawing to defect.

An €18,400 bracket clash sat unresolved for four days because nobody could agree which drawing was actually the current one.

Twigex replaces scattered BIM tools, spreadsheets, and email threads with one connected record per project, so tracing a clash back to the right drawing and the right person takes minutes, not a week of digging.

The problem

What's actually going wrong today.

Design, cost, schedule, and site data all live in different systems, BIM tools, spreadsheets, email, and site apps, that don't talk to each other.

When a defect or cost overrun happens, figuring out who's responsible can take days, because there's no single place to check the facts.

AI tools bolted onto this mess mostly fail, because AI needs clean, connected data to work with, and most construction data isn't set up that way yet.

Built for how construction teams actually work.

One drawing register, not five inboxes of PDFs

The current facade drawing is the only one anyone can build from. The old version is marked automatically, not tracked in someone's inbox.

A clash flagged on site becomes an RFI in one click

A bracket clash photographed on site becomes a numbered RFI, linked to the exact drawing, with cost and schedule impact confirmed in the same thread, not a week of separate emails.

Cost and schedule variance, live against the contract

Cost variance, RFI turnaround, and change order costs update live against the contract, instead of a spreadsheet someone reconciles once a month.

Every RFI and change order, tracked to a close-out

An RFI and the change order it produces sit on the same line, with cost impact, schedule impact, and an owner, so accountability never gets lost between systems.

Why now

The industry doesn't lack AI tools, it lacks connected data. Scattered data is the real bottleneck, and it's the thing most construction firms still haven't fixed.

How Twigex delivers decisive value

Here's how Twigex fixes it.

Shared hub for all site documents
Files and Apps & Projects give every subcontractor and site team one shared hub for drawings, RFIs, change orders, and site reports. No more version confusion.
Unified cost and schedule dashboards
Analytics pulls cost, schedule, and site data into one live view, with dashboards project managers can build themselves and actually trust.
Searchable knowledge graph
The AI Knowledge Platform (coming soon) will make years of drawings, specs, RFIs, and incident reports searchable. Ask which supplier's parts keep showing up in a recurring defect, and get an answer with the source attached, in seconds.
Self-hosted for sensitive contracts
Run Twigex on your own servers, and tender data, subcontractor contracts, and client designs stay on infrastructure you control, something more public and infrastructure contracts now require outright.
