Whether you're prepping for highways works, a new build start, or a complex civils project, the surveys you complete before the summer rush directly shape what comes next: programme risk, design accuracy, safety on site, and how quickly you can hand over.
At GAP, our Survey & Safety division supports contractors across the UK with the latest GNSS, total stations, 3D scanners, drones and detection equipment, and right now, our customers are telling us the same thing: get the surveys done before summer, not during it.
Here are the top 5 surveys worth locking in now:
- Topographical & Setting-Out Surveys
Before any earth moves, your design needs to match the ground.
- Use GNSS rovers and total stations to capture accurate site levels, boundaries and existing features
- Set out control points early so they're protected before plant arrives
- Pair with machine control to drive faster, cleaner earthworks from day one
Common risk: Setting out late means re-surveying around live plant and stored materials, slower, riskier, and more expensive.
- Underground Utility Detection (PAS 128)
Strike risk is one of the biggest avoidable hazards in groundworks, and one of the most expensive when it goes wrong.
- Utilise GPR (ground-penetrating radar) for a fuller picture
- Survey to PAS 128 quality levels so the data stands up in design reviews
- Mark and record findings before excavators turn up on site
Reality: A single struck cable can take a programme down for days. A morning of detection work pays for itself the first time it stops a strike.
- Drone & 3D Scanning Surveys for Baseline Data
Capturing a clean "as-existing" model before works begin gives you something to defend against, and to measure progress with.
- Use drones for fast site-wide capture, including stockpiles, roofs and hard-to-access areas
- Deploy 3D scanners for detailed structural or façade work
- Store the data as your single source of truth for variations, claims and handover
Tip: Spring weather windows are your friend, capture quality drops sharply once heat haze and busier site conditions arrive.
- Environmental Monitoring Baselines
Dust, noise and vibration monitoring isn't just a summer problem, but the summer is when the complaints land.
- Establish baseline dust, noise and vibration readings before works start
- Position monitors with sensitive receptors (schools, residents, hospitals) in mind
- Set alert thresholds that match your planning conditions, not generic defaults
Best practice: Baseline data protects you. If a complaint comes in mid-July, you can show what the site sounded and looked like before you arrived.
- Confined Space, Gas & ATEX Pre-Entry Surveys
If your summer works touch tanks, chambers, shafts or below-ground structures, the safety case needs locking down now.
- Calibrate and bump-test gas detectors before they're deployed
- Survey access routes and pre-position communications equipment
- Confirm ATEX-rated equipment for any zoned areas
Common risk: Confined space entries planned around a tight summer window often slip when last-minute kit shortages hit. Reserve specialist equipment early.
At GAP, we don't just hire out survey kit, our Survey & Safety specialists support you with the right instrument for the job, calibration and verification certificates, technical guidance from accredited engineers, and nationwide availability through our depot network.
Because a survey isn't an admin task. It's the foundation everything else stands on.
