FP McCann's Specialist Precast division provides innovative solution for Kent Beach access scheme

Posted: Friday 2nd June 2017

Following a severe storm in December 2015, resulting in the partial collapse of 250 metres of sea wall and associated damage to the main Dover to Folkestone rail line, a 9 month programme of major work has been undertaken at Shakespeare Beach.

Due to the significant issues involved with constructing something suitable in-situ, Costain contacted FP McCann to investigate an innovative approach in collaboration both with themselves and principal engineer Tony Gee and Partners using an off-site precast concrete system.

FP McCann was asked to develop a modular precast substructure to act as permanent form-work and support for the concrete stair flights already detailed by TGP. This modular structure took into account the logistical challenges in the transportation of the units, the lifting arrangements, and enabled the structure to be erected and secured in the short inter tidal periods available for construction.

Ian Arden Senior Agent for Costain on the scheme said, "As part of the Dover Sea Wall project we were instructed to build a set of stairs to the beach. These steps had to be constructed in the intertidal zone, giving a working window of as little as 3 hours. FP McCann worked closely with Costain to develop a modular staircase utilising both standard and bespoke products. FP McCann's engineered precast concrete structure accounted for both temporary and permanent load cases and met our detailed installation requirements. Their fabrication team were able to turn the production around very quickly, aligning to the site requirements and delivering the modules in a 'just-in-time' manner. FP McCann worked as a true partner throughout and their contribution was key in the delivery of this element of the project."
