Desktop Utility Search Packs / PAS128 Type D

Subvision Surveys is SSIP and ISO accredited, and provides desktop utility search packs, known as C2 utility search packs, stat packs or safe-dig packs, for Tier 1 contractors, developers and planners across London, the South East and nationwide. We request records directly from statutory undertakers and utility providers, review and interpret the findings, and present them in a clear, usable format for your project team, removing the guesswork of working through raw utility company data yourself.

Composite Drawings and Utility Overlays

Unlike providers who only supply the raw search results, Subvision Surveys collates all utility search information and produces a composite drawing, overlaying the data onto either a topographical survey or an OS Tile. This gives clients a single, clear overview of utility assets at the early feasibility stage of a project, rather than a stack of separate records from different utility companies to interpret individually.

Why Choose Subvision for Desktop Utility Search Packs

Because we carry out the desktop search, the composite drawing and any follow-up on-site detection survey ourselves, your project has one team and one point of contact from the earliest feasibility stage through to detailed PAS128 site verification. This means our interpretation of the desktop data is directly informed by what we’ve found on similar sites during on-site surveys, not just the raw records in isolation.

We also provide PAS128 Utility Mapping Surveys and Virtual Trial Holes to verify and build on the information gathered at the desktop search stage.

CAT SURVEY FAQ’S

A Desktop Utility Search Pack, also known as a C2 search, stat pack or safe-dig pack, is a collection of utility asset records obtained directly from statutory undertakers and utility providers for a specific site. It gives an initial indication of what utilities, such as gas, water, electricity and telecoms, may be present beneath or around a site before any physical survey work begins. Subvision Surveys requests, reviews and interprets these records on your behalf, presenting the findings in a clear, usable format for your project team, rather than leaving you to work through raw records from multiple providers yourself.

PAS128 Type D refers to the desktop records search category within the PAS128 utility detection classification. It’s typically the first stage in the utility detection process, based entirely on existing records rather than physical detection on site. As it doesn’t involve any site work, it’s usually the fastest and most cost-effective way to build an initial picture of utility risk on a project, and is often used to inform whether, and to what extent, a follow-up on-site survey (Type C, B or A) is required.

A Desktop Utility Search Pack is best ordered at the earliest, feasibility stage of a project, before budget is committed to design or on-site works. It gives an early indication of utility density and risk in the area, helping inform decisions on site layout, access routes and drilling or excavation positions. Subvision Surveys can turn searches around quickly, so they rarely hold up early project timelines, and the results can directly inform the scope of any follow-up PAS128 on-site detection survey you choose to commission.

A utility composite drawing brings together all the utility search information gathered for a site into a single, overlaid drawing, rather than leaving you with separate records from each utility provider. Subvision Surveys overlays this data onto either a topographical survey or an OS Tile, giving you one clear reference document showing the likely position of utility assets across the site. This is particularly useful at the feasibility stage, helping architects, engineers and planners quickly identify potential constraints without having to cross-reference multiple individual utility company records.

Desktop search results are based on the records utility providers hold, which can vary in accuracy, scale and how recently they were updated. For this reason, a Desktop Search Pack should be treated as an indicative first step rather than a definitive record of what’s underground. Subvision Surveys reviews and interprets these records with that context in mind, and can advise where a follow-up on-site PAS128 survey, such as GPR or electromagnetic detection, is recommended to verify findings before any excavation or drilling work takes place.

Yes. As Subvision Surveys carries out both desktop searches and on-site PAS128 detection surveys ourselves, we can move from a Desktop Search Pack into a Type C, B or A on-site survey using GPR, electromagnetic detection or CCTV, without handing your project between separate providers. This means the same team interprets your desktop data and verifies it on site, giving you a consistent, joined-up picture of utility assets from the earliest feasibility stage through to detailed site verification, rather than reconciling reports from different companies.

Desktop Utility Search Packs are used by Tier 1 contractors, developers, planners and consultants across a wide range of sectors, wherever early-stage utility information is needed to inform design or risk assessment. Subvision Surveys is SSIP and ISO accredited, and provides Desktop Search Packs and composite drawings for clients across London, the South East and nationwide. Whether you need a search for a single site or as part of a larger multi-site programme, we can scale the service to match your project’s requirements and timescales.
