Specialist civil engineer and piling contractor Dawson-Wam Ltd has chosen FP McCann as their supply partner for prestressed, precast concrete wall panels at a new industrial development in Daventry, Northamptonshire.

Work on the development has commenced in April 2019 with the installation of 600 linear metres of king post earth retaining walls. Once complete, the new Canmoor Projects site at Mustang Park will comprise of three brand new industrial sheds ranging from 48,000 sq ft to 171,000 sq ft.

Northern Ireland based Dawson-Wam Ltd is constructing the earth retaining boundary wall on behalf of main building contractor Marbank Construction, with ground engineering solutions company - Geofirma Soils Engineering undertaking the soil stabilisation work.

The wall itself has been designed with retained heights ranging from 1.5 metres and 4.4 metres and the piled galvanised steel king posts have been specially fabricated to facilitate the connection of anchor bars in sections with greater retained heights. In addition to the king posts, over 300 sheet piles will be installed as deadman anchors for the required tie bars.

The 160mm thick and 200mm thick horizontal concrete wall panels were supplied by FP McCann’s Lydney precast facility. The steel king post structure is being fitted with 647 no. standard height, horizontal precast panels and 61 no. non-standard height specials. As the wall is being installed, soil is being backed-up to each section to achieve the required site levels, prior to ground works commencing for the industrial buildings work.

Once complete, the wall will form the perimeter boundary surrounding the new development.

Commenting on the project Site Agent for Dawson Wam, Simon Wilson, says, “The robust prestressed concrete walling panels from FP McCann are the obvious choice to complement our king post piled system, with speed of construction, strength and durability of the finished wall being key benefits in helping us deliver the overall build programme to the client on schedule and to provide a long-term soil retention and boundary solution.”
