Ancillary Works Framework

Project Overview

Client Welsh Government
Form of Contract NEC3
Contract Period 2008 to 2012 & 2013 to 2017

This framework is specifically for the installation of more ‘state-of-the-art’ systems for the gathering and dissemination of information; encompassing roadside communications, electrical work, road tunnel communications and M&E.

Within this framework, we have undertaken various projects covering a wide range of activities.

A465 Section 2 & 3 – Gilwern to Brynmawr / Brynmawr to Clydach

A regional traffic study in 1990 identified the need to improve the A465, defining it as critical to the social and economic regeneration of the Heads of the Valleys area. Accidents on this stretch were concentrated around junctions and areas with poor visibility.

The civil works for Section 2 were delivered by Costain and Section 3 is being delivered by Carillion. Working with both contractors, ERH, under the Ancillary Works Framework, provided/is providing the installation, cabling, testing and commissioning of CCTV cameras, Average Speed Cameras, Emergency Roadside Telephones (ERT) and all associated cabinets. We also provide the Traffic Management using our in-house team.

The improvements will not only increase safety but also improve access to key services, jobs and markets supporting inward investment to areas such as the Ebbw Vale Enterprise Zone.

South Wales Trunk Roads CCTV Upgrade

Under the framework, ERH upgraded the analogue CCTV to IP. The CCTV cameras are used to monitor the Trunk Roads and can be accessed by the public through the Traffic Wales website.

We supplier and installed the back-office system and the IP converters to enable the existing analogue cameras to be used, providing a cost saving to the client. Stakeholders included local authorities and emergency services. The core system was also installed in North Wales, however during the first phase the cameras could only be viewed from here. ERH is now working on the system in North Wales to upgrade this network to IP and bring it fully online.
