SPI Piling were employed by Galldris to help design and prepare costs for this redevelopment of the Surry Quays Basin, where the client is creating a new 3.5-acre public park.
SPI Piling Ltd.’s, worked involved 4 elements:
The 1st element for this redevelopment was the design, supply and installation of a new sheet pile retaining wall to help create the main park within the existing basin dock area.
7.5m EZ18-700 long sheet piles from Maxx Piling were installed with our excavator and side grip vibrating hammer.
Where the water was too deep for a platform to accommodate the excavator then SPI Piling Ltd, turned to conventional piling gates and crane suspended vibrating hammer.
The second element of the redevelopment was the design, supply and installation of a new sheet pile retaining wall to extend the existing shopping area and create more seating and recreational space.
13m long GU27N from Arcelor were installed across one end of the basin and as access was difficult the piles were installed with a silent and vibrationless piler, the crane sat on the existing carpark and pitched piles into the silent piler for installation.
Because of the high retained heights this new wall is tied back to the existing sheet pile wall with a series of waling beams and tie rods.
The third element of the redevelopment was the design, supply and installation of timber piles to enable the construction of a new dipping pond over the new waterways being formed within the park. The timber piles used were 305 x 305mm Ekki hardwood piles at 13m long supplied by Gilmour and Aitken Timber Merchants and they were driven in pairs and form a circle approx. 20m in diameter.
On top of this is a circular board walk so people can look down into the new ponds and streams being formed.
The timber piles will be driven with excavator and side grip vibrating hammer, and as they are load bearing piles, they will then be back driven with a crane suspended impact hammer.
The fourth element of the redevelopment was for the supply and installation of steel tubular piles to support a new raised public boardwalk running the length of the new park.
The tubes are 273mm diameter x 16-17m long and are installed as pairs along the length of the site for the new board walk to sit on, these piles are 100%recycled from Cleveland Steel and tube.
They had to be installed to a great accuracy so they could receive the new steel work on top.
The tubes were pitched and driven with excavator and side grip vibrating hammer then back driven 5-6m into the stiff clays with crane suspended impact hammer.
