As Built Surveys

Checking that what's been built matches the design - before deviations become disputes or delays.

What are As Built Surveys?

An as-built survey records what has actually been constructed and compares it to the approved design. It can be carried out at the end of a package of work or at agreed checkpoints during the programme – making it useful both as a final record and as a live quality-control tool while work is still ongoing.

For project managers, architects and civil engineers, as-built information answers a simple but important question: did we build what we intended to build, and if not, where is the difference? It is commonly used for compliance, adoption, handover, progress sign-off and retention release. It also gives the next trade a dependable record of what is already in place, which matters on phased or fast-track jobs.

Applications

Roads, sewers and external works for adoption submissions
Foundations, cropped piles, slabs and retaining walls
Steelwork, columns, beams and verticality checks
Building footprints, hardstanding and finished levels
Utility routes, chambers and service interfaces
QA checks against design, grid and tolerance requirements

Benefits

Identifies deviations before they become expensive legacy issues
Supports completion certificates, retention release and handover
Gives contractors and consultants a shared factual record
Improves coordination for later trades and facilities teams
Reduces post-completion argument about what was built and where

Deliverables

2D as-built drawings and level plans
3D models, point clouds or surfaces where required
Design-versus-built comparison outputs
Coordinate, level and deviation schedules
Records suitable for road, drainage or asset adoption submissions
Survey evidence packs for QA, handover or client review

Why Choose Powers?

We treat as-built work as more than a final drawing exercise. We can capture data with total station, GNSS or laser scanning depending on the asset and tolerance required, then check it back against the proposed layout to highlight anomalies clearly.

Powers delivers this type of verification on hotel, industrial and infrastructure-led projects, including pile checks, grid marking, steel and slab verification.
