Professional As-Built Drawing Services Across the UK
Our as-built drawing services record completed construction work accurately. Property owners, contractors and consultants get reliable drawings of the building as it was actually built, including its layout, services and site conditions.
We update the original design drawings to show every change made during construction, so you have a clear, up-to-date record of the building.
What Our As-Built Drawing Service Includes
- As-built floor plans: the final layout, including any changes made on site.
- Elevations and sections: the building as built, with final heights and openings.
- Services layouts: drainage, electrical and plumbing routes, where the information is provided.
- Site plans: external works, boundaries and site features as completed.
- Clear records: drawings set out to professional drafting standards.
As-Built Record Drawings for Contractors and Owners
Buildings often change during construction. Walls move, services are re-routed and details are adjusted on site. As-built record drawings capture these changes, so the people who maintain, alter or sell the building have accurate information.
- Meet handover requirements at the end of a project.
- Give building owners an accurate record for maintenance.
- Support future renovations, extensions and repairs.
- Provide information for facilities management and compliance.

As-Built Drawings vs Design Drawings
Design drawings show what was planned. As-built drawings show what was actually built. If you do not have editable drawings of an existing building, our PDF to CAD conversion service can turn old PDFs into CAD files first.
