Premier Technical Services Group PLC (PTSG) has started work on its largest wet riser system yet: at the 75-storey Landmark Pinnacle skyscraper on the Isle of Dogs, London.

Landmark Pinnacle is a 239-metre skyscraper under construction by developer Chalegrove Properties. It is set to be the tallest residential building in Europe and will have more habitable floors than any other building in the UK.

The system is split across three risers – low, mid and high – to provide wet risers across the 75 storeys above ground and two below ground level. The pumping system was commissioned in June to allow the system to be used during construction phase for firefighting purposes.

PTSG has significantly boosted its Fire Solutions capability in recent months, with the acquisition of market-leading companies in different areas of the country. With demand for its life-saving services continuing to grow, it is forecast to become the largest of the Group’s four business divisions.
