The problem

Stop downloading project documents

Construction teams waste time downloading drawings, opening different applications and working out which version is correct. Insite lets your team open project files instantly without leaving the platform.

Multiple downloads

Every review starts with downloading yet another copy of a file.

Version confusion

No one is sure which drawing revision is the current one.

Slow drawing reviews

Comparing revisions by eye is slow and easy to get wrong.

Too many applications

Switching between CAD, Office and PDF tools breaks the workflow.

Lost document revisions

Superseded files linger and get worked from by mistake.

Poor collaboration

Feedback lives in scattered emails instead of on the document.

Frequently asked questions

What is Insite's document management?

Insite gives construction teams one place to view, compare and control project documents, from drawings and PDFs to Office files. Everything stays version-controlled so site and office always work from the latest revision.

What file types can I view?

You can open construction drawings, PDFs and Office files such as Word and Excel directly in Insite, on any device. There is no need to download files into separate apps to read them.

Can I compare drawing revisions?

Yes. You can compare two versions of a drawing side by side or as an overlay, so changes between revisions are easy to spot. This removes the guesswork of checking which drawing is current.

How does version control work?

Every document keeps a clear version history, and the latest revision is always shown by default. You can see who uploaded each version and when, so nothing gets built from an outdated drawing.

Can I search across documents?

Yes. You can search your document library to find a specific drawing, file or record in seconds instead of digging through folders. Documents are organised by project so the right files are always to hand.

Can I control who sees each document?

Yes. You can share documents and control access so the right people see the right files across every project. Records stay secure and centrally managed rather than scattered across inboxes.

What platforms does Insite run on?

Insite is live on iOS, Android and web, so teams can view and compare documents from a phone or tablet on site and manage everything from a browser in the office. Data stays in sync across every project in real time.
