Overview

eSmart Networks were appointed to a framework for Artelia to install 11kV connected EV charging hubs across the UK.

This framework included the first Artelia site in Europe using Tritium PKM 150 EV charging points.

As part of this project eSmart Networks Designed, Built and Installed of new HV substation, including precast bases, network connection and LV pillar terminations.

Challenge

Working on a live forecourt with space restrictions, alongside other contractors with access to only a third of the full site
High risk working environment adjacent to petrol forecourt, so customer wanted to minimise time and construction onsite
Multifaceted legal considerations and work to complete with DNO, IDNO, end client and other landowners

Solution

We used a pre-cast concrete base which allowed for reduced onsite installation times for base, substation, grating and GRP.

Frequent Programme reviews for framework, dedicated onsite manager liaising directly with customer and other contractors to ensure fluidity of installation.

Detailed design work completed as working around hazardous areas with bespoke earthing reports, to ensure safety of install.

We completed local authority negotiations to close a lane of road for completions of works, while maintaining access and allowing Shell to continue to operate business as usual.

Our dedicated legal compliance team ensured the legal status of the site was progressing throughout the project by securing input and answers from the DNO, Artelia and Shell the end customer.

Outcome

The pre-cast base solution, developed alongside industry standards, minimised the time required, number of personnel and vehicles required on site saving both time and money.

With our detailed design works we were able to suggest improvements and agree these back to the DNO. The DNO HV audit also passed first time to allow prompt connection in line with our customer and the end customers required timetable
Our legal compliance team ensuring the status of the site was progressing as needed ensured the programme was achieved.
