At OutsourceCAD, we provide accurate and professional as-built drawing services to capture the final built condition of your project. Whether you're a contractor, architect, or facilities manager, our as-built drawings are essential for verifying installations, ensuring regulatory compliance, and supporting future maintenance or renovation works. We work from redline markups, site surveys, or scan data to produce precise 2D CAD drawings that reflect the true dimensions and layout of your completed project.
As-built drawings are also known as as-installed drawings, as-fitted drawings, record drawings, or as-constructed drawings. These are the same deliverable under different names. As-installed is the standard term in mechanical and electrical work and building services, as-fitted is common in fit-out and marine projects, and record drawings is the formal term used in NEC and JCT contract documentation. Outsource CAD produces all of them.
Our team delivers as-built plans for architectural layouts, structural systems, and MEP installations across residential, commercial, and industrial developments. We ensure that all modifications, deviations, and site changes are documented clearly in the final drawing set. Each drawing is created in line with your templates and layering standards, making them easy to integrate into your project records or facilities management systems.
Clients across the UK, Ireland, and internationally trust OutsourceCAD for timely, detail-oriented as-built drawing support. Whether you’re closing out a construction project, handing over to the client, or updating legacy documentation, our as-built services ensure you have a clear and accurate record of what’s been built. Let us help you deliver complete, compliant, and high-quality documentation that adds long-term value to your project.
Why UK firms outsource as-built drawing production
As-built drawings are rarely the difficult part of a project. They are the part that arrives when nobody has capacity left to do them.
Demand arrives exactly when resource disappears
As-built production falls due at practical completion, when site teams are demobilising, subcontractors have moved on and attention has shifted to final account. The drawing work lands at the point when least drawing capacity is available.
Redlines arrive in every format imaginable
Scanned paper, PDF annotations, photographs of marked-up drawings, and site notes from four different subcontractors. Consolidating that into one coherent set is time-consuming work that requires judgement rather than speed.
The workload is episodic, not constant
A firm sized to handle as-built production at close-out carries that resource through every quieter month in between. Outsourcing provides the capacity only when the projects need it.
Ownership is often unassigned
On many projects nobody is formally responsible for turning redlines into drawings. The gap surfaces at handover, when the health and safety file is being assembled and the drawings are not there.
What a complete as-built package should contain
Every change incorporated, not just the obvious ones
An adequate as-built record reflects all changes made during construction, including the ones recorded badly. Where a markup is ambiguous we query it rather than guess, because an assumed change is worse than a flagged gap.
Correct revision status and issue control
Each drawing carries an updated revision, issue date and title block notation. A design drawing reissued at completion with no changes incorporated is not an as-built record.
Your layer standards, not ours
Drawings are produced to your templates, layer structures and annotation conventions so they drop straight into your existing documentation without reformatting.
Editable CAD, not just PDFs
Delivered in AutoCAD DWG with PDF copies. The DWG is what makes the record usable when the building changes again in five years.
What it costs and what drives the price
Redlines cost less than surveys
Where original drawings exist and changes were recorded during construction, as-built drawings can be produced without a measured survey. That removes the site visit, the survey cost and the processing time before drawing work can even begin.
Complexity drives cost, not sheet count
A drawing with three dimension changes costs considerably less than one requiring substantial re-draw. Pricing is per drawing based on the volume of change to be incorporated, quoted before work starts.
Incomplete redlines cost more than complete ones
Where the markup record has gaps, resolving them takes time. Consolidating redlines into a single set per drawing before sending them reduces both cost and turnaround.
Ongoing programmes work differently
For continuous redline flow — oil and gas modifications, telecoms rollouts, M&E; maintenance — we operate dedicated team arrangements with agreed throughput and a shared tracking register.
