Utility surveys are one of the simplest ways to de-risk excavation, drainage or piling — but only if they’re scheduled early. In this guide, we break down how long a full PAS 128 utility survey really takes, what happens on-site vs during CAD processing, and when it should sit within your programme to avoid redesign, service strikes and stand-down costs.

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.

Not everything beneath the surface is meant to be found. Some underground utilities are classified — hidden for national security reasons. Learn how utility surveyors identify the invisible networks that keep the UK running safely without ever appearing on a plan.
