VolkerGround Engineering was contracted by Marcus Worthington Group to install 150no. 750mm bearing piles to depths of 13m. The works were to enable the construction of a high specification commercial property in Deansgate, Manchester. The team completed the piling using a PVE 55 rig.

The works taking place at 125 Deansgate, are part of a larger plan to redevelop properties on one of Manchester’s most famous streets.

Working in collaboration with the client’s engineer, Fairhursts, our design team were able to develop a foundation solution which was vital for this city centre site.

With a fast-paced build programme from the main contractor, the team worked within an excavated basement to install bearing piles from a lower level.

Working within the basement, VolkerGround Engineering was able to achieve 1.2m clearance from the centre of a number of piles to the existing wall. This allowed the main contractor to complete its excavation prior to the piling works.

The experience and expertise of the VolkerGround Engineering team was vital to the successful completion of this project. Due to the shallow depth of drift overlying the red Manchester sandstone, the team formed deep rock sockets using the capabilities of the PVE55 piling rig, to support the development. Static load testing was undertaken to verify that the design met the client’s tight performance criteria of low settlement.
