Site Survey

A site survey is a pre-installation visit to a customer's premises to assess physical conditions, take measurements, identify access constraints, and gather the information needed to produce an accurate quote or scope of works.

What a Site Survey Covers

The scope of a site survey varies by industry, but the underlying purpose is consistent: confirm that the information used to price and plan the job reflects the actual conditions on site, not an assumption. A site survey carried out before quoting reduces the risk of discovering mid-job that cable routes are longer than expected, that access requires specialist equipment, or that existing fittings need removal before new work can begin.

In construction and electrical contracting, a site survey typically covers room dimensions, access routes, existing services (power, plumbing, structural elements), hazards, and delivery logistics. In renewables installations, it includes roof pitch and condition, shading analysis, consumer unit location, and DNO connection requirements. For AV integrators, it means measuring the room, assessing existing cabling infrastructure, confirming wall and ceiling construction for mounting, and noting ambient light or acoustic challenges. Contract furniture dealers use surveys to confirm floor plans, door widths, lift access, and any restrictions on delivery timing.

A site survey is usually followed by a detailed report or survey form, which feeds directly into the quote or specification document.

Survey-to-Quote Discipline

The value of a site survey is only realized if the findings feed accurately into the quote. This is where the process often breaks down in smaller businesses: the surveyor visits the site and records their findings on paper or mentally, but those details do not translate cleanly into the quote. The priced scope ends up reflecting what the estimator assumed rather than what the site visit confirmed.

Good survey-to-quote discipline means capturing findings in a structured format - ideally on a digital form that attaches directly to the job record - so that everyone pricing the work is reading from the same information. It also means the survey findings are available when the job goes live, not just at the point of quoting, so the installation team knows what they found before arriving on site.

Zigaflow eForms allow site survey findings to be captured digitally on a mobile device and linked directly to the relevant quote or job, replacing paper survey sheets and the transcription errors that come with them.
