The Wave is the first building of two 14-storey, 55m high buildings providing prime office space in an area steeped in history, located next to the Baltic coast and clearly visible on the landscape.
Winning the project was a result of significant collaboration with construction teams on both the side of the cladding system manufacturer based in Poland, as well as Tata Steel. The project’s success was mainly due to the pro-active approach of supply chain partner Pruszynski’s sales team liaising and working closely with the Tata Steel representatives based in Poland, the customer technical services team based in Shotton North Wales, and the end client. This collaboration focussed around two key areas for the client - the aesthetic finish and the sustainability credentials of the chosen products.
In terms of the aesthetics, Pruszynski have a wide range of façade products which they manufacture from Colorcoat® products however, for a building of this magnitude a bespoke cladding solution was needed. The team worked together to produce life size mock-ups of the bespoke profiles in several colours, from which the client chose Colorcoat Prisma® in Seren Copper from the many colour options put forward for the façade.
Each of the modules comprised trapezoidal sheets in trays with special flashings protecting each façade element. The profiles were manufactured using around 49 tonnes of Colorcoat Prisma® pre-finished steel in Seren Copper, which clad the external façade, with a small amount used internally. The profiles were lightweight and assembled on site.
The designers also had an objective to follow LEED certification. To support this aim, Tata Steel’s technical team in Shotton produced a detailed report that indicated how Colorcoat Prisma® contributed to maximising points in LEED certification. These credentials included a product specific EPD according to EN 15804, an independent VOC A+ rating and also the product performance benefits in use. Colorcoat Prisma® pre-finished steel not only provides an attractive finish to external façades, but in addition the innovative three-layer product pushes the boundaries for UV performance and outperforms the highest European corrosion resistance standards. This durability significantly reduces the whole life carbon cost of the building.
So complex was the cladding solution that it fell outside standard guarantee offering due not only to the height of the building, but to the complex detailing of the profiles. At the system manufacturers’ request, Tata Steel developed a tailored statement of performance for the project which offered cover for a period of time that the client was happy with.
Due to the location of the site and the extremely restricted access around the buildings as well as the unusual height for steel clad buildings, careful consideration had to be made at the design stage to providing adequate safe access to all areas to facilitate inspection and maintenance of the cladding made from Colorcoat Prisma® during the lifespan of the building.
