Pen y Cymoedd Wind Energy Project
The joint venture behind Vattenfall’s Pen y Cymoedd wind energy project has made good progress during the first two months of 2015 constructing England and Wales’ largest on-shore wind farm.
Civil engineering firms Jones Bros and Balfour Beatty have completed 40 of the wind farm’s 76 turbine bases since starting work on the project one year ago.
Preparatory work is currently underway at eight further locations, ahead of concreting work, which is due to re-commence in March 2015.
Eryl Roberts, project manager for the Jones Bros and Balfour Beatty joint venture, said:
We’re continuing to make good progress and are now working towards concreting work getting underway again following the winter months.
By mid-May we will be starting work in the western region, the final of four geographical areas that the project is divided into. We are also due to begin site investigation work there to check such factors as soil quality.
Work in the western region includes constructing eleven turbine bases, building 6.2 km of new site tracks and improvements to a further 2.8 km of existing tracks, and the establishment of a new welfare compound.
Each turbine base takes approximately four weeks to complete from start to finish, starting with an excavation about 4.5 m deep and 25 m in diameters. Each of the turbine bases require up to 610 m³ of concrete and 84 tonnes of steel reinforcement, whilst 7,000 metres of cable trenching and laying has been done to date.
Kawneer is key to Royal Borough regeneration
Facade products from Kawneer architectural aluminium systems have provided a "key" aesthetic in the first phase of a 10-year redevelopment of an estate in a Royal London Borough.
Kawneer windows, doors and AA 100 zone and mullion-drained curtain walling with 50 mm sightlines feature throughout the elevations of Block 1 of Portobello Square, at the heart of the £250 million regeneration by the Catalyst Housing Group of the Wornington Green estate in North Kensington.
The specified windows include AA 541 top hung and side hung composite casement windows. In addition to this, oversized AA 543 tilturns, bottom hung windows and AA 720 French casements incorporating ‘hidden' vent profiles were used to allow natural light to flood the rooms.
The Kawneer doors used on the project included AA 720 open-in and open-out doors and series 190 heavy-duty commercial entrance doors.
