Precision data for sustainable decisions. Survey methodology that matches the environment.

Construction & Civil Engineering

Environmental and energy projects in the North West present survey challenges that standard construction methodology cannot always address. Wetland sites where ground-based access is restricted or harmful to the habitat. River corridors where the data needed lies beneath the water surface. Wind farm and solar development sites across challenging Pennine, Lakeland and moorland terrain. Flood risk assessments where every level and drainage feature matters to the modelling. Water infrastructure upgrade schemes operating under AMP8 investment where the survey data directly underpins programme-critical design decisions.

Site Surveying Services has been delivering survey across this sector since 1997 — using UAV LiDAR, unmanned surface vessels, remote sensing and GPS-controlled ground survey to capture data safely and accurately in environments where traditional methods are impractical, too slow or potentially damaging to what is being surveyed. We are Lancashire-based, nationally capable, and our equipment is specifically chosen for the environments this sector demands.

Surveying for Construction and Civil Engineering Projects

Surveying for Construction and Civil Engineering Projects

Construction projects demand speed, accuracy, and coordination between multiple trades.

Yet even the smallest survey error or misalignment can cascade into costly rework, design clashes, or safety issues on-site. Contractors and developers need survey partners who understand the pressures of live sites: who can adapt quickly, deliver precisely, and keep projects on track no matter how complex the environment.

Why Accuracy Matters...

Every measurement, level, and coordinate influences the success of the final build. Accurate, coordinated survey data ensures that construction moves forward with confidence, allowing teams to:

Build safely

ensuring structures, excavations, and utilities align to design tolerances.

Reduce delays

avoiding rework and costly downtime caused by inaccurate or incomplete data.

Improve collaboration

providing unified datasets that integrate seamlessly with design, engineering, and BIM platforms.

Meet compliance standards

delivering verifiable records for QA, as-builts, and handover documentation.

Optimise efficiency

reducing repeat visits, downtime, and reliance on multiple contractors.

Innovation in Action

Innovation in Action

We combine traditional engineering expertise with modern digital workflows.

From laser scanning and drone data to BIM coordination, our technology enables faster decisions, fewer errors, and a complete record of every stage of construction. Our goal: to make accurate data the easiest part of your project.

Frequently Asked Questions

Frequently Asked Questions

What survey is needed before a construction programme begins?

Every construction programme should begin with three pre-start survey activities. First, a topographic survey of the site — confirming existing ground levels, drainage, boundaries, services at surface and contextual features that the design depends on. Second, PAS 128 utility mapping to the quality level the programme requires — QLC at minimum, QLA at any location where excavation is planned and the consequence of a service strike is significant. Third, a control network — primary and secondary survey control installed, verified and documented before any setting-out or construction activity begins. These three surveys collectively protect the programme from the most common and most costly pre-construction surprises.

The Construction Design and Management Regulations 2015 require the principal designer to gather pre-construction information — including information about utilities and underground services — before any construction begins. PAS 128 utility mapping is the standard methodology for satisfying this requirement on programmes involving excavation. Quality Level A physical verification is typically required where excavation is adjacent to high-pressure gas, high-voltage electricity, strategic water mains or other services where a strike would have serious consequences. Our PAS 128 accreditation, Constructionline Gold and CDM compliance are all current and available for pre-qualification documentation immediately.

Our setting-out engineers are integrated into the construction programme — not occasional visitors. They work from the same design files as the structural engineer and drainage designer, check the data for consistency before they set out from it, flag conflicts between the design and the existing site conditions before concrete is poured, and verify as-built at programme milestones. On visiting arrangements they attend on agreed days each week — matched to the setting-out demand of the programme. On full-time placements they are present continuously. In both cases they are directly employed by Site Surveying Services and carry our professional indemnity insurance.

Quality Level C — active detection using GPR and EML across the full works extent — is the appropriate baseline before any ground investigation or non-critical excavation. Quality Level A — physical verification at vacuum excavation test points — is required at locations where the design depends on accurate knowledge of service depth and position: structure foundations, drainage connections, service crossing points and any excavation where a strike would have significant programme or safety consequences. The right distribution of QLA test points across a construction site depends on the ground conditions, the service density and the specific works programme. We advise on this at the time of scoping.

Yes — and this is one of the most significant advantages of commissioning both from the same firm. Where we have produced the pre-construction topographic survey, the setting-out engineer working on the programme has access to the same spatial dataset, the same coordinate system and the same knowledge of the existing ground conditions. There is no translation between the survey firm and the setting-out team. The spatial knowledge of the site is consistent throughout the programme — from the first GPS observation to the last as-built check.

The monitoring requirement depends on the excavation depth, the proximity to existing structures and infrastructure, the ground conditions and the structural sensitivity of what is adjacent. As a general principle, monitoring is appropriate for any excavation within approximately 1.5 to 2 times the excavation depth of existing structures. Settlement monitoring using precise levelling and structural movement monitoring using total station prism targets are the standard methods. Trigger levels are set by the geotechnical or structural engineer — we implement the monitoring programme to those trigger levels and report immediately when readings approach or reach threshold, not at the next scheduled visit.

A pre-construction condition survey is a photographic and written record of the existing condition of structures adjacent to proposed works — recording all existing cracks, defects, settlement, distortion and signs of distress before construction activity begins. It establishes a baseline that protects the contractor in the event of third-party claims for construction damage. Without a pre-construction condition survey, it is impossible to demonstrate that damage to a neighbouring property pre-existed rather than resulted from the construction programme. We produce pre-construction condition surveys as a standard part of all monitoring commissions.

Yes. As-built topographic survey at practical completion — confirming earthworks levels, drainage inverts, structure positions and all built features against the design — is a standard part of our service to contractors and developers. Delivered in AutoCAD DWG in the format required by the planning authority and highways engineer for condition discharge. CCTV drainage survey of completed drainage for adoption is also available, coordinated alongside the topographic as-built.

Yes. We currently deliver survey for Kier and BAM Nuttall and are experienced in the pre-qualification, method statement, CDM and programme requirements of tier 1 construction and infrastructure supply chains. Our Constructionline Gold accreditation satisfies the pre-qualification requirements of most tier 1 contractor frameworks immediately. We are also registered on Builders Profile and Avetta. If your supply chain has specific pre-qualification requirements, contact us and we will confirm our compliance status quickly.
