Reliability isn’t attendance — it’s what a site engineering partner does when a quality check finds a problem. What to check before you book, and why continuity of people matters as much as continuity of data.

The right pre-construction survey work eliminates five of the most expensive risks on a UK project before breaking ground: utility strikes, dimensional disputes, setting-out errors, drainage assumptions and as-built gaps. Here's the survey that removes each.

Specifying long-term site engineering well means defining scope, deliverables, standards and resourcing up front, so it can be priced accurately on a day rate. Get those clear and you avoid the gaps that lead to rework, disputes and standing time on a long programme.

PAS 128 defines four utility survey quality levels and how each must be carried out and recorded. A compliant survey tells you not only where a service is, but how confident you can be in that position.
