Haringey District Heating Scheme: Utility Search and Utility Mapping
Project overview:
In 2021 the UK government announced plans for a major expansion of heat network projects to power homes with green energy. Heat networks – also known as district heating – supply heat from a central source to multiple sites via underground pipes carrying hot water. The system is efficient as individual boilers are replaced by a central heating source.
Haringey Council have been awarded funding for two such projects – Wood Green District Heating Network and the Tottenham Hale and Broadwater Farm District Heating Network. When completed these two networks will supply heat to almost 10,000 homes.
A major engineering consultancy appointed Premier Energy to undertake a Utility Record Search and PALM 128 Utility Map in order to assist them in the planning and route proving stage of the project.
Premier Energy have a track record of delivery high quality utility search reports and clear utility mapping, particularly on complex urban engineering schemes. This project covered over 700 ha of north London.
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 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 to be viewed in any combination. This makes it simple for users to view complex utility information in a simple straightforward format whilst understanding the proximity of proposed works to existing utility equipment.
For this project the PALM 128 was used as part of a route proving assessment. The PALMs clear presentation of existing utilities helped our clients engineering team to determine the most economic, safe and potentially quickest route of installation.
Client benefits
After an initial consultation with our client, it was agreed that the PALM 128 would show different voltages and gas pressures on their own layers. By allowing users to view these networks in isolation it made the identification of major constraints easier, aiding the overall route proving and planning process.
Our client was working to a tight schedule so a staggered delivery schedule was agreed.
Premier Energy delivered the finished PALM128 Utility Maps as an interactive PDFs as well as DWGs for integration into CAD systems.
