Swansea Council working together with the Welsh Government approved major refurbishment works to the Pentrehafod School Estate.

W. Morris, the Bridgend based Building Services Contractors, were appointed to carry out the mechanical works on the project. They chose Pump House on the day to supply all the rooftop building services support frameworks, which in turn picked up several Nuaire air handling units, and a series of condensers.

Our frameworks are hot dip galvanised, and are supplied in lengths and widths to suit each unit being supported. With all products being available from stock, the contractor could order frameworks last minute. Pump House even met the goods on site, to provide the contractor with assistance in building up our solutions.

Pump House had to overcome the challenge of supporting the services on a level framework, whilst contending with two significant roof falls, one roof with a two degree fall, and the other roof with a three degree fall. To overcome this problem, Pump House supplied an alternative foot to their usual standard product. Our alternative dense crumb rubber moulded feet are available with either a 2.5-degree, or 5 degree slope cut to the underside. At Pentrehafod School we supplied our 2.5 degree, 350mm square feet to enabled our frameworks to work with both roof falls that were present.

All support frames come complete with adjustable legs incorporating M24 height adjusters, enabling the installer to level the frameworks. With a fast installation time, all frameworks can be assembled very quickly as fixings are also supplied.
