Pre-Construction Site Inspection Checklist

The pre-construction site inspection is the check you carry out before any work starts. It establishes the baseline condition of the site, confirms you can build safely and legally, and surfaces the problems that are far cheaper to deal with now than after the diggers arrive. Skipping it is how projects discover buried services, boundary disputes, and access nightmares the hard way.

This checklist covers what a pre-construction site inspection should examine.

Site context and boundaries

Site boundaries confirmed against the legal plan and clearly marked.
Adjacent properties and structures identified.
Existing rights of way, easements, and wayleaves noted.
Trees and vegetation, including any protected by orders.

Existing conditions and baseline records

Photographic and written condition survey of the site as found.
Condition survey of neighbouring/adjacent structures (vital for later party-wall or damage disputes).
Existing structures to be retained or demolished identified.
Existing levels and topography recorded.

Ground and below-ground

Ground conditions and any available ground investigation/soil reports reviewed.
Existing and buried services located — electricity, gas, water, drainage, telecoms (use service drawings and detection).
Contamination risks and previous land use considered.
Watercourses, drainage, and flood risk noted.

Access and logistics

Site access points and their suitability for construction traffic.
Road conditions, restrictions, and any need for permits.
Space for welfare, storage, and material laydown.
Crane and plant positioning and oversailing considerations.
Public interfaces — footpaths, neighbours, schools.

Utilities and connections

Availability of temporary supplies (power, water).
Location of existing connections and where new connections will come from.
Any diversions required before work starts.

Health, safety, and environment

Site-specific hazards identified for the construction phase plan.
Security and public-protection requirements (hoarding, fencing).
Environmental constraints — protected species, watercourses, dust/noise-sensitive neighbours.
Emergency access and welfare provision.

Documentation and approvals

Planning permission and conditions in place.
Building control arrangements confirmed.
Permits and licences (highways, scaffold, skip) identified.
Required notifications made.

Why the baseline record matters most

If you take one thing from a pre-construction inspection, make it the documented baseline. Photographs and notes of the site and neighbouring structures before you start are your protection against claims that your works caused damage that was already there. Reconstructing this after the fact is impossible — the moment passes once work begins.

Capturing it well

A pre-construction inspection generates a lot of photos and notes that need to be organised, dated, and retrievable years later. Capturing them on a site inspection app — each photo tagged with location and timestamp, held against the project — means your baseline record is complete, structured, and instantly accessible if a dispute ever arises.

Key takeaways

A pre-construction site inspection establishes the baseline and surfaces problems before work starts: confirm boundaries, record existing conditions (including neighbouring structures), locate buried services and ground risks, assess access and logistics, check utilities, identify HSE and environmental constraints, and confirm approvals. Above all, capture a dated photographic baseline — it's your best protection later.
