Farncombe to Petersfield Rail Upgrade: Utility Search and Utility Mapping

Project Overview

Between 2022 and 2024 civil engineers will carry out a large program of signalling, track and level crossing improvements on the Farncombe and Petersfield section of the London to Portsmouth rail line.

A major engineering consultancy appointed Premier Energy to undertake a Utility Record Search and PALM 128 Utility Map in order to assist them on the project. Premier Energy have a track record of delivery high quality Utility Search Reports and clear Utility Mapping that are both PAS128 and HSG47 compliant.

Utility records are an essential resource that can help civil engineering companies prevent accidents, injuries, and damage to underground infrastructure during construction. They provide a detailed map of the location of underground utility lines, allowing engineers to plan and design their projects around them.

At the project outset Premier Energy agreed the exact area of interest and delivery specifications with the client. The route to be mapped was 21 miles long and the project was therefore split into 21 sections making the reports and mapping easy-to-use. Our client recognizes the critical importance of working with up-to-date utility asset information and therefore instructed Premier Energy to undertake a new Utility Record Search and create an updated PALM 128 Utility Map every 3 months for the duration of the project.


Premier Utility Search Report:

Using our intelligent search processes, we identified over 30 utility companies who were known to operate in and around the area. These were contacted by our dedicated in-house team of utility search experts.

The Utility Search Report comprised all the C2 utility maps retuned by the incumbent utility companies as well as maps from independent network operators in the vicinity. The report included our intuitive RAG rating system to clearly identify affected utility companies within the site, and those nearby or adjacent to the site. The Utility Search Report was delivered within 20 working days of the initial order and was fully PAS128 (Quality Level D) and HSG47 compliant.


PALM 128 Utility Map:

The PALM 128 is our innovative multi-layered interactive utility map that brings together all the utility assets from C2 utility records into a single georeferenced utility map. The PALM 128 is fully compliant with PAS 128 making it an essential information source for Health and Safety compliance. Utilities are displayed in separate layers and can be turned on/off in order to be viewed in any combination. This makes it simple for users to view complex utility records in a simple straightforward format whilst understanding the proximity to work location of existing utility equipment. The final PALM 128 utility map was delivered as an interactive PDF and DWG.


How we helped our Client

The Utility Search Report covered the full length of the 63km cable route with the PALM128 Utility Map clearly showing the affected utilities within an agreed buffer of the rail line. The PALM128 Utility Map was delivered as an interactive PDF for use in the office and could also be accessed on site via a suitable tablet device. The PALM 128 was also delivered as a DWG for use in CAD systems.

Together the Utility Search Report and PALM 128 utility mapping provided our client with clear, easy to interpret information essential for project planning and fulfilling health and safety obligations.
