New phase for Simplex


Simplex Foundations is installing 550 piles over a six week period to provide foundations for a new business park near Leeds.

The work is for the second phase of the Leeds Valley Park, which is being built by Bowmer and Kirkland for developer Akeler. This phase consists of two commercial office complexes known as Ellington and Darwin.

The hilltop site requires piling on two levels for both buildings.

The piles on the lower level provide foundations for a concrete retaining wall, while those on the higher level are for the buildings' foundations.

On the lower level of the Ellington building, Simplex is installing 138 CFA piles, of which 75 are 500mm in diameter and 63 are 400mm. A further 156 CFA piles - all 400mm diameter - are ging in on the higher level.

Construction of the Darwin building requires the installation of 67 CFA piles of 500mm diameter and 52 of 400mm diameter on the lower level, and 136 CFA piles of 400mm diameter on the higher level.

Average pile depths are 12m on Ellington and 16.5m on Darwin - all toed into the bedrock.

Simplex has been operating on site with two rigs: a Casagrande B150 and a Soilmec R312.
