FP MCCANN PRECAST CONCRETE FIREWALL INSTALLED ON WELSH POWER GRID STABILITY FACILITY

Project: Precast Concrete Fire Walls – Rothienorman Grid Stability Facility, Aberdeenshire

Client: Welsh Power

Civil Engineering Contractor: RJ McLeod

Precast Fire Wall Installation: FP McCann

Products Supplied: FP McCann 4 hour rated steel reinforced precast concrete fire walls

FP McCann has supplied and installed a 4-hour rated firewall as part of a new development to construct the Rothienorman Grid Stability Facility in Aberdeenshire. The energy management facility comprises a new electricity infrastructure compound including plant rooms, transmission compound and access road.

The project will see the developer, Welsh Power, deliver a new facility to provide inertia to strengthen the grid and short circuit power to ensure a reliable operation and reactive power for voltage control.

To protect the high voltage transformer and the Grid Stability Building, FP McCann working alongside Dingwall based specialist civil engineer RJ McLeod (Contractors) Ltd, has installed a three-bay 4 hour rated precast concrete firewall measuring approximately 10 metres high by 15 metres wide. The wall has been constructed using FP McCann steel reinforced precast concrete ‘H’ columns and special prestressed precast concrete horizontal wall panels, all manufactured at the Company’s Lydney factory in Gloucestershire.

Each of the 4 supporting ‘H’ columns weighing 15.50 tonnes and measuring 11.63m high have been located in a pre-formed concrete foundation. The three precast concrete wall bays consist of 30 No. individual prestressed horizontal wall panels measuring 4.250m wide and 4.450m wide. Each panel is 200mm thick with weights ranging between 0.915 tonnes and 2.225 tonnes.

Commenting on the installation of the precast concrete fire protection wall, Kevin Smith, Site Agent for RJ McLeod says, “FP McCann delivered and installed the firewall to meet our tight construction programme. Installation was a speedy and simple process and the use of off-site manufactured precast concrete products, has significantly reduced the amount of formwork and wet concrete trades on site in comparison to traditional in-situ construction”

FP McCann steel reinforced precast concrete fire walls are designed to contain fire from 30 minutes up to 4 hours, depending on the thickness of the panels specified. Rapid installation is possible due to the tongue and grooved joints. Standard column sections vary dependant on overall wall height and are made to order to suit customer requirements. Fire walls and columns can be manufactured to the client’s own design or to FP McCann’s design specification
