Solar Farm Setting Out & Pile Position Surveys, Nationwide

South East Site Engineers set out ground-mount solar arrays for EPC contractors, piling contractors and developers across the UK. We mark pile positions, track and fence lines, cable routes and equipment pads straight from your design coordinates. With up to 1,000 piles set out a day, your piling rigs get clear marks and never stand waiting for an engineer.Request a solar setting out quote Call 020 7278 0778

Setting out engineers on call for solar PV contractors

Solar programmes depend on piling. One late or wrongly set out row can hold up the whole mounting structure installation. We fit into your programme as an extra setting out team, for a single day or for the full piling phase.

EPC contractorsSetting out capacity that grows with your piling programme, with no full-time engineer on your payroll.

Piling contractorsPile positions marked ahead of your rigs, plus as-built checks to prove your piles are within tolerance.

Mounting structure installersRow lines, pile centres and level checks so the racking goes up square and true.

Developers & IPPsPre-construction topographic surveys and independent as-built records for handover and asset owners.What we set out and survey

Solar farm surveying services from greenfield to handover

Pile position setting out

Every pile marked from your pile schedule or CAD layout, using GNSS and robotic total stations tied into OS National Grid (OSGB36) and your site control.

Site control & datum levels

We install and check primary control, run closed-loop traverses and transfer datum levels, so every team on site works from the same reliable grid.

As-built pile surveys

We record installed pile positions and levels and compare them with design. You get clear deviation reports for QA sign-off and handover.

Tracks, fences & cable routes

Access tracks, perimeter security fencing, CCTV columns, trench and cable routes, and inverter, transformer and substation pads.

Pre-construction topo surveys

Topographic and drone and point cloud surveys of large fields, plus cut and fill calculations for groundworks.

Buried services & cable routes

GPR utility surveys to find existing services before you trench grid connections or pile near field boundaries.

Hundreds of solar farm pile positions set out with white and red flags across a field — Pile positions set out across a ground-mount solar array, flagged row by row for the piling crew.

Built for large sites

Accurate pile setting out at solar farm scale

A solar farm has thousands of near-identical positions spread over open, often uneven ground. Our engineers prepare your coordinates in the office before they arrive. On site they set out row by row with GNSS rovers and robotic total stations, and colour-code the markers so your piling crew can tell rows, ends and special piles apart. On open, prepared ground we can set out up to 1,000 piles a day.

We work to the tolerances in your specification. We check control at the start and end of each shift, so errors don’t spread across the array.Discuss your solar project

Walk the array: solar farm pile positions ready for piling

This video walks along a finished set-out on one of our solar farm sites. Every flag is a surveyed pile position, laid out in straight, consistent rows and ready for the piling rigs.

Each set-out comes with the records your QA team needs: what was set out, when, by whom, and against which drawing revision.How it works

From pile schedule to piling-ready site

Send your dataShare your layout DWG/DXF or pile schedule (CSV), the site control and the programme dates.
Office preparationWe check the coordinates, flag any clashes or design gaps, and plan the set-out sequence around your piling.
Set out on siteEngineers set up and check control, then mark piles and features ahead of your rigs, on a day rate or fixed price.
As-built & reportingInstalled piles surveyed, with as-built data and deviation reports issued in CSV, DWG or PDF.
