About Xponent

The contractor EPCs bring in for the mechanical, civil & electrical scope.

Xponent Energy Solutions works alongside EPCs, developers and asset owners on ground-mount solar PV sites, taking on the construction-phase scope: site survey and inspection, piling and load testing, mechanical installation, civil and electrical works, revamping and OEM support.

We combine hands-on piling and geotechnical experience with practical design input, helping EPC teams de-risk the build phase rather than just execute a fixed spec.

Services, by discipline

Engage us for the full construction-phase scope, or bring us in for a single discipline alongside your own EPC team.

01 · SURVEY

Survey & GPS Flagging

Site survey and GPS setting-out ahead of piling and civil works, so the build starts from accurate ground data.

02 · SURVEY

Site Inspection

Qualified engineer inspection of ground conditions, feeding geotechnical advice into the piling design.

03 · MECHANICAL

Piling & Load Testing

Pull-out and load test results ahead of full piling installation, matched to the site's ground conditions.

04 · MECHANICAL

Full Mechanical Scope

Racking and mounting system installation through to module install, with QA sign-off on every row.

05 · CIVILS

Civil Works

Access roads, cable ducting, drainage and general civil engineering across the site.

06 · ELECTRICAL

Electrical Works

DC/AC electrical installation delivered as part of the wider EPC electrical scope.

07 · LIFECYCLE

Revamping

Refurbishment and upgrade works on existing ground-mount solar sites.

08 · PARTNERSHIP

OEM Services

Installation and technical support services delivered on behalf of equipment manufacturers.

09 · ADVISORY

Design & Advisory Support

Practical input to EPC design teams, drawing on our piling experience and geotechnical knowledge.

How we run a build

A programme you can actually track

We sequence our mechanical, civil, and electrical crews around your master programme dates — eliminating subcontractor hand-off friction and providing transparent, auditable progress on site.

EPC Delivery Standards

  • ✓
    CDM 2015 Compliant

    Daily RAMS briefings, toolbox talks, and site supervisor sign-off.

  • ✓
    De-risked Groundworks

    Calibrated pull-out testing before volume piling commences.

  • ✓
    Weekly Milestone Tracking

    Progress logs shared directly with your EPC project director.

01
Stage 1 · Pre-Construction Step 01

Site survey & inspection

We walk the site, carry out GPS flagging and a qualified engineer inspection, and return pull-out/load test results before piling design is finalised.

✓ Pull-out & load test calibration report
02
Stage 2 · Mobilisation Step 02

Scope & mobilisation

Scope is agreed with the EPC or developer, plant and crews are mobilised to site, and teams are briefed with RAMS specific to the site.

✓ Site-specific RAMS & plant induction pack
03
Stage 3 · Foundations & Civils Step 03

Piling & civils

Piling installation runs alongside access roads, trenching and drainage, sequenced to keep mechanical crews fed with completed ground.

✓ Sequenced ground release for mechanical crews
04
Stage 4 · Mechanical & Electrical Step 04

Mechanical & electrical install

Racking, module install and electrical works run as coordinated crews, tracked against a weekly progress plan shared with the EPC.

✓ Weekly progress Gantt & string alignment QA
05
Stage 5 · Snagging & Handover Step 05

Snagging & handover

QA checks and snagging are closed out discipline by discipline, with a documented handover back to the EPC or main contractor.

✓ Discipline-by-discipline handover documentation
