The twin 430 x 100 x 64kg PFC steel walings, installed on the rear of the permanent piled wall as part of the project, were manufactured to specification in the VolkerBrooks steel fabrication workshops in Morecambe. The design required some very tight curves in some locations, which were still achieved, despite the size of the steel channels.
The design for a new concrete wave wall on the project was detailed and in some sections was curved in three dimensions, calling for some complex curved formwork. This is where the skills of VolkerBrooks were able to be utilised to the fullest; with in-house expertise in design and the capability to manufacture any kind of complex shape. The curved formwork, again manufactured in the VolkerBrooks workshops in Morecambe, was delivered to site fitted with RMD falsework (also designed and supplied by VolkerBrooks), ready for use straight from the wagons.
Patterned formwork required to create a concrete facing to the piled wall along the beach, was also supplied to the project by VolkerBrooks. This was achieved by gluing a moulded liner to a variety of straight and curved timber shutters to provide a random stone effect finish to the in-situ concrete.
Steve Holt VolkerBrooks general manager, said: "Curved formwork is something we do a lot of and for which we are widely recognised; the skills we have in-house can provide bespoke formwork shapes. By closely working with clients, we can develop solutions related to each project. The patterned formwork we made for Colwyn Bay was designed and manufactured so that it could be used several times throughout the length of the job, with the minimum amount of shutters; this saved cost and time as well as reducing the number of wagon movements required to site, thereby reducing the projects carbon footprint."
