Construction surveying
A surveyor on your site from groundbreaking to handover: re-establishing axes, controlling levels and verticality, floor-by-floor as-built schemes.
Licensed service · EL-845/2026
Construction surveying is continuous control that makes sure a design turns into a real structure exactly as drawn. Our surveyor works on site at every stage from foundations to roof: re-establishing building axes, checking formwork, setting levels before concrete is poured and recording the actual position of what has been built.
The service is aimed at general contractors, developers, technical supervision engineers and private clients building their own homes. On a high-rise, even a small deviation accumulates floor by floor and later causes serious trouble when installing the facade, lift shafts and building services. Timely measurements prevent costly demolition and rework.
We use SOUTH total stations with 1"–2" angular accuracy, GNSS RTK receivers (±1–2 cm in plan) and digital levels. Elevations are transferred up the building by levelling and vertical projection, and every result is compared with the tolerances of the applicable building codes (AzDTN/SNiP).
Each check is recorded in the site survey log, and as-built schemes are passed promptly to the contractor and the supervising engineer.
When you need it
- Construction of multi-storey residential and office buildings
- Before concreting monolithic frames, columns and slabs
- Erection of steel structures for industrial buildings and warehouses
- Foundation and wall stages of private houses and villas
- When technical supervision or the client requires an independent check
What's included
- Establishing and protecting the site setting-out network
- Re-establishing building axes at each stage and marking them on formwork
- Level control of foundations, columns, slabs and stairs
- Verticality checks of walls, columns and lift shafts
- Checking anchor bolts, embedded items and steelwork positions
- Floor-by-floor as-built surveys and deviation calculations
How we work
- Review of design documents and agreeing a survey schedule
- Checking control points and building the setting-out network
- Setting axes and levels before each construction stage
- Control measurements after concreting and erection
- Preparing as-built schemes and handing them to the contractor
Deliverables
