Morgan Sindall is one of the UK's leading construction and infrastructure companies, delivering major projects across sectors including utilities, highways, rail, and public infrastructure. On large infrastructure projects, PAS128-compliant utility surveys are increasingly specified by clients and required by CDM regulations and framework conditions.

The challenge Morgan Sindall identified was not at the operative level. Their project managers, the people responsible for commissioning utility surveys, accepting survey deliverables, and managing the risk of utility strikes on major projects, did not have sufficient grounding in what PAS128 actually requires. They understood that PAS128 surveys were required. They did not always understand what a compliant survey should look like, what the different PAS128 quality levels mean in practice, or what their own legal obligations were when a survey deliverable was handed to them.

The risk was straightforward: if a project manager does not know what a compliant PAS128 Quality Level B survey looks like, they cannot effectively verify that the survey they have received meets the standard they have specified. That is a legal and commercial exposure.

Morgan Sindall wanted leadership-level briefings, not a hands-on course, but structured sessions that gave their project management teams the knowledge to make better decisions about utility surveys, specify them correctly, challenge surveyors where needed, and understand their duty of care.

PAS128 is the UK standard for underground utility detection, verification, and location. Published by the British Standards Institution, PAS128 defines the methodology and quality levels that govern how buried utilities and buried services are located, mapped, and recorded on construction and infrastructure projects. It exists because inaccurate or incomplete utility mapping is one of the most common causes of project delays, cost overruns, and safety incidents on UK construction sites.

The standard defines four survey types, each corresponding to a quality level. Type D is a desktop search of existing utility records and stats plans. Type C is a site reconnaissance involving visual inspection of surface features to corroborate desktop records. Type B is utility detection using electromagnetic locating equipment such as CAT and Genny devices and ground penetrating radar to detect and map buried services beneath the surface. Type A is verification by excavation, where trial holes confirm the exact location, depth, and condition of underground utilities.

Each survey type produces data at a corresponding quality level, from QL-D through to QL-A. The quality level assigned to the data indicates the confidence that can be placed in the accuracy of the utility location information. A project manager who commissions a PAS128 survey needs to understand what quality level is appropriate for the project risk, what detection methods will be used, what the survey deliverables should contain, and how to verify that the survey report meets the specification.

PAS128 utility survey training exists at multiple levels. At the operative level, training courses teach surveyors and locating operatives how to use electromagnetic locators, signal generators, and ground penetrating radar equipment to detect and map buried utilities in the field. At the management level, training focuses on understanding PAS128 requirements, specifying compliant surveys, and verifying deliverables. The Morgan Sindall programme sits firmly at the management level.

Briefing Module	What It Covers
What is PAS128 and Why Does It Exist?	An accessible introduction to PAS128: what the standard is, why it was developed, who is required to use it, and what it actually requires at a document and process level. Project managers leave this module knowing precisely what PAS128 is and is not.
PAS128 Quality Levels: What They Mean	A structured walkthrough of PAS128 Quality Levels D, C, B, and A. What does each level actually require in terms of technology, methodology, and deliverables? What risks does each level mitigate and what risks remain? Project managers learn to match the quality level to the project risk.
Legal Duty of Care and CDM Obligations	The legal framework around underground utility survey and excavation under CDM regulations, HSG47, and PAS128. Who holds the legal responsibility at each stage of a project: the client, the principal designer, the principal contractor, the project manager? What does a utility strike cost legally, financially, and reputationally?
How to Specify a Compliant PAS128 Survey	Practical guidance on what to include in a survey specification to ensure the survey delivered meets the quality level required. How to write the brief, what to specify about the deliverables, and what to ask for in the survey report to confirm compliance.
How to Verify What You Have Received	How a project manager can check whether a survey report meets PAS128 requirements without being a surveyor. What should be in the report? What does a Quality Level B deliverable include that a Quality Level D does not? How to challenge a survey that does not appear to meet specification.
PAS128 in the Context of Major Infrastructure Frameworks	How PAS128 requirements flow through frameworks and contracts. What clients typically specify, where contractors carry risk, and how to ensure that survey procurement decisions made early in a project do not create liability that only becomes visible when something goes wrong.

A significant part of the Morgan Sindall briefing programme focuses on PAS128 survey types and the quality levels they produce. Understanding these levels is essential for any project manager who commissions utility surveys or accepts survey deliverables on construction projects.

Type D: Desktop Search

A Type D survey is a desktop search of existing utility records. This involves requesting stats plans from utility companies and reviewing existing mapping data held by asset owners. The data produced is Quality Level D. It shows approximate locations of buried services based on records that may be decades old and may not reflect the current position or condition of underground utilities. Type D data is a starting point, not a definitive record.

Type C: Site Reconnaissance

A Type C survey adds a site reconnaissance to the desktop data. A surveyor visits the site to carry out a visual inspection, identifying surface features such as manholes, valve covers, marker posts, and other evidence of buried services. The surveyor corroborates the desktop records against what is visible on the ground. The data produced is Quality Level C. It is more reliable than QL-D because it has been verified against physical evidence, but it does not involve any below-ground detection.

Type B: Utility Detection

A Type B survey uses detection equipment to locate buried utilities beneath the surface. This is where electromagnetic locating devices such as CAT and Genny equipment and ground penetrating radar are deployed on the survey site. Trained utility surveyors use these detection methods to identify the position and, where possible, the depth of underground services. The data produced is Quality Level B. It represents the most comprehensive non-invasive utility mapping available under PAS128 and is the level most commonly specified on major infrastructure and construction projects.

Type A: Verification by Excavation

A Type A survey involves physical excavation to verify the exact location, depth, size, and condition of a buried utility. This produces Quality Level A data, the highest confidence level in PAS128. It is typically used at critical points on a project where absolute certainty about utility location is required before construction proceeds.

For Morgan Sindall's project managers, the critical knowledge is not how to operate detection equipment. It is how to determine which quality level a project requires, how to specify that level in the survey brief, and how to verify that the deliverable meets the specification. That is what these briefings deliver.

The briefing sessions are designed to fit into a project manager's working schedule. They are not full-day courses. Each module can be delivered as a standalone briefing or as part of a structured half-day or full-day programme depending on Morgan Sindall's scheduling requirements and the depth of knowledge the team needs.

Delivery is classroom-based, at Morgan Sindall facilities or at a Sygma training venue. The sessions work best with small groups of 6 to 10 project managers who can engage in discussion. The briefing format includes structured Q&A throughout, not a lecture.

All delegates complete Sygma's QR-code feedback form. Trainer scores remain private until the following working day. Morgan Sindall's L&D or H&S team receives a full group report.

What This Training Is Not

These briefings are not PAS128 utility survey training at the operative level. Morgan Sindall's project managers are not learning to use CAT and Genny locating equipment, ground penetrating radar, or any other detection devices. They are not being trained to conduct utility surveys themselves. Sygma delivers separate training courses for operatives who carry out utility detection and utility mapping work on site, including CAT and Genny training, PAS128 awareness courses, and utility mapping training programmes. The Morgan Sindall programme is specifically for the people who commission, specify, and verify that survey work.

Outcome	How the Programme Delivers It
Project managers can specify PAS128 surveys correctly	The specification module gives practical, usable guidance, not theory. Managers leave with a framework they can apply immediately.
Legal exposure from poor survey specification is understood and reduced	The legal duty of care module names the responsibilities at each project role. No ambiguity about where liability sits.
PAS128 quality levels are no longer a mystery	The quality levels module translates PAS128 language into practical decision-making criteria that project managers can use.
Survey deliverables can be challenged effectively	Managers know what a compliant report should contain and can verify or challenge what they receive.
Framework and contract risk is better understood	The infrastructure frameworks module gives context for where utility survey risk sits in the procurement and delivery chain.

PAS128 utility survey training operates at multiple levels within an organisation. At the operative level, locating operatives and utility surveyors attend training courses that teach them to use electromagnetic locating equipment, signal generators, and ground penetrating radar to detect, locate, and map buried utilities and buried services on construction sites. These training courses cover detection methods, surveying methodology, data collection, and the practical skills needed to produce reliable survey data that meets PAS128 requirements.

At the management level, the training need is different. Project managers, contract managers, and site leadership teams need to understand PAS128 well enough to make informed decisions about utility mapping on their projects. They need to know what survey types exist, what quality levels mean, how to specify a compliant survey, how to read and challenge survey deliverables, and where their legal duty of care sits under CDM regulations and HSG47 guidance.

The Morgan Sindall programme bridges a gap that exists in many construction and infrastructure organisations. Operative-level CAT and Genny training and utility mapping training ensure that the people conducting utility surveys are competent. But if the people commissioning those surveys do not understand what they are asking for, the risk of specifying the wrong survey level, accepting non-compliant deliverables, or failing to act on survey data remains. PAS128 leadership briefings close that gap.

Sygma delivers both levels of PAS128 utility survey training. For operatives, Sygma offers CAT and Genny training courses, advanced locating training, PAS128 awareness courses, and utility mapping training programmes delivered nationwide. For managers and project leaders, Sygma designs bespoke briefing programmes like the one delivered to Morgan Sindall, tailored to the organisation's projects, frameworks, and risk profile.
