Setting out puts the design into the ground; 3D scanning verifies what was built. Used together they catch errors early, confirm tolerance and produce a defensible as-built record — one team, one control network.

Piling setting out positions every pile to the design as the rig works. Accurate, independently checked set-out avoids rig standing time, remedial piles and redesign — and an as-built survey keeps the foundations defensible.

The real cost of a setting-out error is rarely the survey — it's the rework, delay and disputes that follow. A misplaced foundation can cost tens of thousands, long after the small cost of getting it right the first time.

An engineering register records a site's survey framework — control points, topographic data, calibration certificates and survey targets — while the site diary logs the daily setting out. Kept separate and complete, the two form a defensible record that protects the contractor at final account.

Winter utility surveys can be a smart planning move when sites are accessible and diversion lead times are critical. This guide explains when PAS 128 surveys work well in winter, when weather creates real limitations, and how contractors can plan ahead for early-2026 projects.

PAS 128 survey types can be confusing if you’re not working with them day-to-day. This guide breaks down M1, M2, B, C and D in simple terms so project managers, engineers and contractors can choose the right survey level and manage underground utility risk confidently.

PAS 128 sets the standard for underground utility surveys in UK construction. This guide explains what each survey type means, how to interpret confidence levels, and how PAS 128 helps reduce risk on highways and civils projects before you break ground.

Pot-ended and abandoned cables are some of the hardest buried services to identify. This blog explains why standard detection methods can’t locate them, what this means for PAS 128 surveys, and how project teams can plan safer excavations despite these limitations.

 Before any as-built report leaves our office, it goes through a detailed internal verification process. Here’s how AKN Engineering ensures accuracy and consistency before client sign-off.
