the Mgeni Viaduct in Durban, SA, which consists of two independent, pre-stressed concrete single cell box girders with a total length of 410 meters and nine spans. The viaduct was incrementally launched at a nine per cent gradient from the east abutment, with the launching system being supplied by Enerpac. The launching system is required to restrain the deck at 1.3 times the down slope force of the deck, assuming zero friction. The system also needed to be able to pull the deck back in the event of a bearing miss-feed with a maximum force 10.500 kN. This was achieved by using 3 x 350 ton hollow plunger cylinders coupled
The vital link A
n Enerpac spindle bar bridge launching system has been used to launch the deck on
to the deck via retaining sticks installed through the box section and connected to the cylinders via 75 mm Macalloy bars. The cylinders were set up behind the left abutment with the macalloy bars running through the abutment. These are the largest cylinders made by Enerpac to date. For further information visit

R Services have designed and installed a balustrade in the Glass and Glazing Federation’s head office in
London. The GGF’s Chief Executive Nigel Rees commented, “The idea is to showcase the very best that the industry has to offer: energy efficient windows, top performing lass and leading designs”. The DR-yR Shoe is designed to hold balustrades made of toughened glass or toughened laminated glass up to 26mm thick. Other design features include 2mm feet on each side, which aid in making the glass completely vertical. The aluminium shoe is fixed to the finished floor surface using cap screws and washers.

ilo recently supplied their pumps to a hospital project in Portsmouth. The Queen Alexandra Hospital had been demolished and rebuilt piece by piece and this created certain requirements for the consultants and contractors to consider for the required outcomes. The small site that the hospital was sat on meant that it was
difficult demolishing parts of the building, whilst remaining functional in other parts. Storage space was an issue so the site had to have materials delivered, as they needed them to prevent a build up of produce. For further information visit
