The extensive expansion of the office building at 1 Triton Square on Regent’s Place in Euston, London, is creating new space for tomorrow’s working environment. fischer Zykon panel anchors FZP II were used together with nuts and drilling technology by the fixings expert to securely install the limestone façade.
Multiple global firms have offices on Regent’s Place, a 13-hectare campus in London’s West End. These include Facebook, Santander Bank, the investment management company Dimensional Fund Advisors L.P., the headquarters of the British department store chain Debenhams and many other renowned names. But Regent’s Place also contains retail and restaurant spaces as well as other recreational facilities.
The development of Regent’s Place, which has already undergone extensive renovation, is making progress with the refurbishment project at 1 Triton Square, due to be carried out between 2018 and 2021. Upon completion, the project by the building contractor British Land Company PLC will house modern and flexible office spaces. The offices are grouped around a large main atrium that connects levels and people with one another.
The majority of the existing façade and extension was reused and partially refurbished, which coincided with the project’s sustainable BREEAM-certified (Building Research Establishment Environmental Assessment Methodology) approach.
New façade surfaces were also added over the course of the building’s extension. Façade panels by the natural stone supplier Mineral by Eberhart GmbH headquartered in Saarwellingen, Saarland, were installed over a surface of approx 2,300m2. The panels consist of the French “Val de Nod” limestone and measure 900mm x 450mm x 40mm. The limestone panels were securely installed in the anchor base using approx 24,000 fischer Zykon-panel anchors FZP II. The undercut anchors were supplied with nuts featuring a custom geometry. The façade system consists of stainless steel (A4) and is therefore corrosion resistant.
The Zykon panel anchors FZP II are installed in natural stone without expansion pressure. “To begin with, conical drill holes are created before an undercut hole is drilled,” commented Detlef Postler, project support fischer façade systems. “Next, the anchors simply need to be expanded using the setting tool before being connected with the substructure. We offer complete systems with the corresponding accessories from a single source for this purpose.”
“In comparison to edge fastenings, the load-bearing capacity increases and the bending stress of the panel is reduced by up to 50 per cent by attaching the anchors to the reverse side in a structurally optimised position, the so-called 1/5 point,” explained Steven-Henrik Maier, market manager fischer façade systems. “The undercut anchors also provide optical advantages in comparison to edge fastenings by providing a harmonious look between the gaps without any visible fixings elements.”
“We offered the right solution for the project, consisting of undercut anchors, nuts and drilling technology. Also thanks to local expertise at our national subsidiary fischer UK, we were able to provide not only prompt engineering support for those involved with the construction project, consisting of planning and calculation services, but also on-site assistance by our local ACT expert Jeff Holmes. We will continue to do so until the project's successful completion,” concluded Detlef Postler.
