Home / Service / As-Built Documentation

As-built drawings show the final constructed state of a building after works are complete, including any deviations from the original design. We deliver comprehensive as-built documentation captured directly from 3D laser scan data, not estimation, giving you full traceability from field measurement to final drawing. Every dimension is verifiable against the source data.
Whether you need as built drawings for a building handover, an industrial facility, or a long-term asset record, our documentation is dispute-resistant and ready for use by design teams, insurance teams, and facilities managers. Michael personally signs off every large as-built package before it leaves us.

From scope definition to certified handover, one point of contact the whole way.
On every as-built documentation project, you’ll work directly with Michael Kiernan, GeoMaus’s founder, from first call to delivered handover package. No project coordinators relaying messages, no waiting for someone to check with someone else. When something changes or a deadline shifts, you’re speaking to the person who can make the call that day.
Traceable documentation for building compliance, handover, and legacy rescue.
As-constructed floor plans showing final building layout, structural openings, and services. Annotated with level datums and dimension chains. The core of any building as built drawings package.
External and internal elevations with material indications, crack mapping, and condition notes for building conservation or insurance.
Structural sections showing construction build-up, floor-to-ceiling heights, and foundation depth where accessible. Critical for building control approval.
Registered point cloud overlaid with CAD extraction for audit trail and dispute resolution for the building. Proves every dimension in your as built drawings.
Post-construction building services layouts with red-line mark-ups, pipe sizes, and plant schedules. Essential for building O&M handover and facilities management.
RICS-compliant validation report with deviation analysis, assumptions register, and sign-off certificate for the building. Completes your as built drawing services package.
Construction never matches the original design exactly. As-built documentation records what was actually built so the building owner and operating teams have a current, dispute-resistant record going forward.
You’ve inherited a building with no drawings, or drawings that don’t reflect what’s there. A new as-built package gives you a current baseline you can plan from.
Insurance, defect liability, and contractual disputes turn on verifiable measurements. As-built drawings captured from scan data give you a documented record that holds up under scrutiny.
You need a permanent digital record of the building for asset management, maintenance planning, and lifecycle decisions. As-built documentation becomes the foundational reference for the next 20 years of decisions.
Before redesigning the building, you need to know what’s actually there. Verified as-built drawings give your design team the dimensional baseline they need.
