Most clients ask for a 'GPR survey' when what they actually need is PAS 128 detection. This guide explains what GPR can and can't do, how it fits into Type B investigations, and what a proper survey pack should include.

The Permit to Dig process protects excavation works on UK civils projects. We explain who signs it, what must be verified and how to reduce underground service risk before breaking ground.

Confusion around underground utility responsibility is a major cause of delay on UK civils projects. We explain who owns what and how early coordination protects programme and safety.

Total stations can achieve millimetre accuracy — but only with verified control and proper setup. We explain what affects real-world survey precision on UK highway and civils projects.

Programme delays on highway works usually start with assumptions about control and responsibility between packages. We explain how main contractors use site engineering to prevent avoidable delays and protect commercial performance on Section 278, Section 38 and civils framework schemes.

Utility records searches and PAS 128 surveys are often confused, but they serve different purposes at different project stages. We explain what each delivers, how they impact design and construction, and when UK contractors should use each option for cost, safety, and compliance.

Site Engineers, Setting Out Engineers and Surveyors are often treated as interchangeable, but on UK civils projects the differences matter for competence, documentation and delivery. This guide explains the roles clearly and why it matters for contractors, PMs, QSs and international engineers.

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.

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.

Using the wrong UK coordinate system can mean centimetre-level misalignments. Learn how to avoid costly errors with OSM15 vs OSM32.

Moving from CAD drawing to ground needs millimetre precision. Discover how AKN Engineering sets out DWG plans to keep your project on time and on spec.

Learn how to align GNSS with local site coordinates and why calibration files are critical for highways and machine control projects.

An as-built survey is more than a drawing – it’s proof of what’s been built. Here’s what it tells you, why it matters, and how it helps contractors and clients.

Before you break ground, are you sure what lies beneath? From PAS 128 standards to survey turnaround times, here’s what every PM should ask before hiring a utility surveyor.

Think the Building Safety Act only applies to high-rise flats? Think again. Here's what site engineers, surveyors, and contractors need to know—and how to stay compliant on infrastructure and highways projects.

Design and build only work when you know what’s above and below ground. Discover how topo + utility surveys lead to smarter, safer project starts.

Underground cables and pipes can turn into costly delays. Learn how a PAS 128 utility survey helps avoid strikes, improve safety, and keep your site moving.

Before you break ground, what’s under the surface? Learn how utilities surveys help prevent delays, reduce risk, and improve planning on highways and building projects.
