FK Lowry successfully delivers another Dublin Basement Scheme

10 Jun 2019

FK Lowry have successfully delivered another Secant Bored Pile Retaining Wall Scheme at One Wilton, Dublin for Principal Contractor Sisk. The piling scheme, valued at €1.5M, involved the design and installation of 273 linear metres of Hard/Firm Secant Bored Pile Wall for a Double Storey Basement for a new Commercial Development for Iput at Wilton Terrace. FK Lowry mobilised their Soilmec SR-75 and SR-95 dual purpose piling rigs to undertake 900mm dia. primary piles to depths of up to 10m and founding into the underlying Limestone Bedrock. 700mm/600mm Secondary Piles were then installed to depths of up to 16m including up to 6m of rock socket. FK Lowry also designed and installed 91 No. Glass Fibre Reinforced Polymer (GFRP) Anchors to provide temporary restraint to the hard/firm secant bored pile wall. This was one of the largest uses of GFRP Anchors on an individual Basement Project in Dublin City Centre.

The Ground Conditions were described as Made Ground overlying stiff Dublin Black Boulder clay before moderately strong to strong Limestone Bedrock was encountered. Robbie Foster, FK Lowry Works Supervisor explains, “We are delighted with the outcome of the scheme and the collaborative relationship that we developed at the commencement of the project meant that we worked extremely closely with Sisk to successfully deliver the scheme safely , to time and to budget. The Safety of our staff and the safe operation of our plant is our number one priority at FK Lowry and we worked collaboratively with the Principal Contractor to ensure excellent lines of communication were maintained throughout our works.”

FK Lowry’s dual purpose piling rigs are ideally suited for the installation of Secant & Contiguous Bored Pile Retaining Walls in Rock. This is due to their high torque capability and specialist German Engineered Tools, Wear Parts and Consumables.
