PORTOBELLO STAR

We were engaged by a specialist outdoor media company to install a piled foundation base for a giant digital advertising screen to be placed on an ornamental tower next to the elevated section of the A40 in West London.

The site was sandwiched between the Hammersmith and City tube line and the elevated section of the A40. Detailed method statement and risk assessments had to be produced to satisfy transport for London that the work could be carried out safely in this sensitive location. Purkelly utilised its specialist mini-piling equipment to install 9no 350mm diameter piles 16.5m deep into the London Clay. Each pile was heavily reinforced with prefabricated reinforcement cages for the full depth of pile. When the piling was complete, we set about excavating for the substantial reinforced concrete base. The 20 square metre, 1.5m thick reinforced concrete slab was constructed using temporary sheet piles to provide earthwork support whilst the 3.0 tonnes of reinforcement was fixed in-situ.

Holding down bolts were fixed in position using a template supplied by the manufacturers of the tower prior to concreting and everything was checked twice as the dimensions were critical. Once the concrete had been placed and cured, the temporary sheet piles were withdrawn and the site left clean and tidy for the media company to erect the 26.5m high tower and giant digital screen. This difficult contract was carried out within the specified timescale and for the price quoted.

TRADITIONAL UNDERPINNING

Client: Shire Structures Ltd
Location: The White House, Keyworth

We provided Traditional Underpinning for this property in Keyworth, Nottingham for an insurance claim due to subsidence.

MINI-PILING

Client: Shire Structures Ltd
Location: Isle of Wight

We recently visited the Isle of Wight to install 4 x 300mm piles as recommended for stability of this beautiful house.  The access was limited, so the main contractor asked us to carry out the works with our mini piling machines to overcome this space issue.
