DriffieldClarity Before Construction
Demolition & Remediation Surveying
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 Demolition and Remediation Projects
Surveying for Demolition and Remediation Projects
…from unstable structures and unknown utilities to environmental hazards and access restrictions. Without accurate, up-to-date data, teams face uncertainty that can result in safety incidents, programme delays, or costly redesigns. Developers and contractors need absolute clarity before works begin – an understanding of every structural, environmental, and subsurface condition that could impact safety and success.
Why Accuracy Matters...
Accurate survey data is essential in helping to protect ecosystems and supporting sustainability goals. With reliable information, clients can:
Identify hazards early
Detecting structural weaknesses, contamination zones, or utility conflicts before mobilisation.
Plan safe access routes
Mapping clear working zones, exclusion areas, and haulage routes.
Optimise remediation design
Using detailed models to guide excavation, drainage, and earthworks strategies.
Stay compliant
Providing essential documentation for health, safety, and environmental assessments.
Support redevelopment
Delivering precise data that transitions smoothly into the design and construction phase.
Innovation in Action
Innovation in Action
These technologies reduce the need for manual inspection, enable safer planning, and ensure compliance with environmental and demolition regulations – transforming how projects are managed from first survey to final clearance.
Our Services
Topographical Surveys
OS-controlled accurate, efficient and cost effective surveys for highways, civils and development. Cad and BIM-ready output.
PAS 128 utility mapping
Providing the location of underground services in 2D or 3D through qualified utility mapping surveys, using advanced GPR and Electromagnetic Location.
Measured building survey
Delivering accurate as-built information that supports design, refurbishment, planning and construction with the latest technology. Producing reliable drawings and digital models.

Frequently Asked Questions
Frequently Asked Questions
What survey is required before a demolition programme begins?
Pre-demolition survey typically requires a combination of services depending on what is being demolished, what is being retained, and what the site will become after demolition. Measured building survey of the existing structures before demolition begins — providing the record that satisfies the planning authority’s requirement and protecting the contractor if any dispute arises about the pre-demolition condition of the building. PAS 128 utility mapping before any groundworks associated with the demolition programme — particularly important on brownfield sites with complex buried service histories. Topographic survey of the site before and after demolition for cut and fill and earthworks assessment. Monitoring of adjacent structures where demolition activity creates movement risk for neighbouring buildings.
Why is PAS 128 utility mapping particularly important on brownfield and demolition sites?
Brownfield sites and sites with existing structures carry the highest risk of undocumented buried services of any site type. Decades of service modifications, decommissioned service runs abandoned in place, undocumented connections between systems and services not represented in any statutory record are all common on brownfield land. PAS 128 Quality Level A — physical verification using vacuum excavation — is the appropriate standard before any demolition-associated groundworks on these sites. A service strike during demolition groundworks has the same consequences as one during construction. The standard that protects the programme applies equally to both.
Do you carry out pre-demolition measured building surveys?
Yes. A pre-demolition measured building survey produces a complete record of the existing structure before demolition — floor plans, elevations, sections and in some cases a laser scan point cloud — providing the documentary evidence that satisfies planning condition requirements, supports heritage recording where the building has historic significance, and protects the contractor in the event of any dispute about the pre-demolition condition. For listed buildings or buildings in conservation areas where demolition requires consent, the measured building survey is typically a condition of that consent.
What monitoring is required during demolition adjacent to existing structures?
Where demolition takes place in proximity to existing occupied buildings, structures or infrastructure, monitoring is required to detect and document any movement caused by the demolition programme. Settlement monitoring of adjacent structures, crack monitoring of existing fabric and vibration monitoring from demolition plant are all appropriate depending on the proximity, the sensitivity of adjacent structures and the demolition methodology. The trigger levels and monitoring programme should be specified by a structural engineer and implemented before demolition begins — not after movement is suspected.
Can you survey a contaminated or hazardous site?
We survey on sites where ground contamination is a known or suspected risk, adapted to the specific hazard profile. Where site investigation has identified contamination, we review the Phase 1 and Phase 2 environmental reports before mobilisation and produce method statements that reflect the specific hazard controls required. We do not carry out intrusive investigation of contaminated land — that is a specialist environmental engineering activity. We carry out topographic survey, UAV survey, laser scanning and other non-intrusive survey methodologies on sites where contamination is present, subject to appropriate hazard controls.
What UAV survey deliverables are useful for demolition and remediation programmes?
UAV survey is particularly useful for demolition and remediation in three specific applications. Pre-demolition site survey — rapid capture of the existing site conditions before demolition begins, including the roofs and upper facades of structures that ground-based survey cannot efficiently capture. Volumetric survey during remediation — tracking earthworks progress, material removal volumes and stockpile quantities throughout the remediation programme. Post-demolition as-built — confirming that demolition and remediation have achieved the required outcomes against the design specification.
