Gas Peaking Power Plant, Ebbw Vale

Designed, Supplied & Installed Acoustic Fencing

Wilson Stone Contracting Ltd are specialist contractors to the energy sector.

Integrated Fencing were approached by Wilson Stone Contracting Ltd regarding a project in South Wales that they were let down on by another contractor. The project included the design, build and energisation of a 20MW gas peaking power plant in Ebbw Vale, South Wales. The five-month project was connected to Western Power Distribution (WPD) network in February 2021. The complete project involved full civil and electrical design, procurement of electrical equipment for the private network, construction of the gas peaking power plant, installation of switchgear, transformers and generators, and final testing of all components prior to energisation.

Integrated Fencing at the site in Ebbw Vale to ascertain the full scope of works that was required.

This job was to take place at Lords Cricket Ground in London. In January 2019, Marylebone Cricket club were granted permission by Westminster City Council to construct the two new three-tier stands. The construction of the new stands is scheduled to start in late August 2019 and be completed for the 2021 season. Most of the build will be carried out during the off-season and be completely halted for major matches. This was to ensure that no games were interrupted by having work going on so everyone was tasked to get their jobs done when there was no games taking place.

The fence would need to comply with the current crowd loading of 1.5kl/m. After a few proposals Integrated Fencing needed to develop this detail into a workable design and specification. The use of a D grade Oak post was Introduced. And a Sample piece was developed for approval. With some minor tweaks the design was near complete. We now added a steel shoe manufactured to house the oak post onto the precast concrete wall. The Design was then approved, and we went about sourcing the raw material which proved challenging with the COVID restrictions. Once we managed to source the timber, the oak would be milled to size and shape and then kiln dried.

Key Information

Our acoustic panels all conformed and tested to BS EN 1793
The average density of the system was 26.4kg/M2 excluding the posts
Project was completed ahead of schedule and within 12 weeks

Project Outline

Further to a full and comprehensive site survey and a personal consultation, it was established that the scope of works included the design, manufacture, and installation of a 3m high timber reflective acoustic fencing around the sub-station.

There was also a requirement for a large acoustic entrance gate, which was constructed as a double leaf gate for vehicles to gain entrance to the site, a wicket gate was also installed within the framework, which allowed essential pedestrian access.

Project Challenges

Due to the high altitude of the site, we recognised immediately that the system would have to withstand extreme weather and wind conditions, therefore, we installed 250mm RSJ posts at 2m centres and excavated to a depth of 1.7m which were backfilled with mass concrete to ensure there would be no movement within the posts.

Project Completed

Our acoustic panels all conformed and tested to BS EN 1793 and compliant with Highway Sector Scheme 2C for the prefabrication of environmental barriers. The average density of the system was 26.4kg/M2 excluding the posts. All timber used on this project was FSC certified.

Although the main purpose of the system was to provide an acoustic barrier, it also had to be anti-climb for security reasons, therefore, we designed, manufactured, and installed hot dipped, galvanised angle brackets around the perimeter of the site to hold three rows of barbed wire. This would secure the site and deter any unwanted visitors.

Due to the five-month construction build of the project, we completed the manufacture and full installation of this project within twelve weeks, which was ahead of schedule and the given deadline. Integrated Fencing solutions follow all social distancing and safety measures on site. This includes mask wearing, hand washing and social distancing which was taken into consideration with our deadline to complete work on site.
