McGee Construction selects RMD Kwikform formwork and falsework to achieve a Grade A concrete finish for the new basement extension at London’s Tate modern gallery.
Having been awarded the contract to extend the basement of the landmark Tate Modern gallery on the south bank of the Thames river, McGee Construction required a formwork and falsework solution that could be used in the very tight confines of the site.
Due to the challenging design of the extension, which required a Grade A concrete finish, due to the concrete work remaining exposed after completion, McGee Construction put the design and supply out to competitive tender, with RMD Kwikform awarded the project.
RMD Kwikform’s southern region general manager, Neil Thomas spoke about the project challenges, “The formwork and falsework for the project represented the first phase of the construction of an extension to the Tate Modern Gallery. Unlike standard basement extensions this also involved the redevelopment of three old oil tanks, stored in the ground.
“A lot of the attractive concrete features involved in this project were peculiar rigging shore columns, constructed at various angles, so the light deflects at different degrees and casts shapes across the floor. This required some challenging work on behalf of McGee’s and RMD Kwikform. The key to the solution was to ensure the design of formwork and falsework was able to safely support the structures, whilst leaving enough room for work to be carried out in the confined spaces.”
In addition to the formwork challenge, the RMD Kwikform project team had to work closely with McGee to overcome the logistical issues onsite. With a central London location and limited space, just in time deliveries had to be scheduled and the design team had to visit the site in order to determine how to design a workable solution.
To achieve the high quality finish, RMD Kwikform incorporated the ply layout within the falsework design, which proved very challenging. The end result is one that will impress visitors walking from the existing to the new extension, with an almost marble effect finish achieved between the old concrete and the new.
