Solutions provided by Peikko: DELTABEAM® Green, T Beams and PETRA® Slab Hangers, Peikko Column Shoes and Anchor Bolts
Meeting the highest environmental standards, Peikko was approached to develop a DELTABEAM® solution by PCE Ltd, a hybrid structures specialist for the redevelopment of the Fitzrovia at 247 Tottenham Court Road, London in the United Kingdom.
The Fitzrovia was recently redeveloped into a 7,990 m2 mixed-use scheme, providing an area of 6,038 m2 grade A office space and 1,021 m2 prime retail space, as well as eight premium residential units. Peikko’s DELTABEAM® Green is used to support five suspended floors and the roof. Peikko also delivered T Beams and PETRA® Slab Hangers, as well as Peikko Column Shoes and Anchor Bolts in precast columns.
With its innovative approach to building materials, the prefabricated DELTABEAM® Green allowed for flexible layouts through the lifespan of the building, as well as easy HVAC installation.
Taking a Designed for Manufacture & Assembly (DfMA) approach, Peikko met with PCE and the design team to revisit the initial design of the project. This plan was modified to use precast columns and DELTABEAM® Green, using a 250 mm hollowcore and 50 mm leveling screed. The original 75 mm structural topping was omitted as part of the value engineering exercise. The tie across the slab was then achieved via the hollowcore alone, which also meant tie beams could be removed further minimizing materials. This approach combined the advantages of modern precast technology with efficient material use, leading to cost savings and faster project completion while maintaining structural integrity.
Being a prop-free solution, Peikko’s column shoes and anchor bolts further allowed for the stability of the columns during construction which enabled the safe installation of prefabricated components.
Peikko also worked with the design team to incorporate cladding fixings. This proved invaluable to PCE as it significantly reduced working hours not having to set out on site and greatly improved tolerances. Edge protection fixing was also fabricated to the beams, allowing leading-edge barriers to be fitted ahead of the beam’s installation. At L5, transfer beams were used to set back the roof to open to a communal terrace.
“The Peikko DELTABEAM® Green system has proven invaluable. It reduces the need for extensive temporary works, creates a cleaner site with fewer labour resources and supports just-in-time deliveries. This allows us to streamline the construction process, improving efficiency while maintaining safety and quality,” says Darren Waller, PCE Senior Project Manager.
To ensure that products of only the highest standard were used, Peikko’s Lithuanian DELTABEAM® factory was subject to a quality assurance audit at the request of the contractor, Kier Construction. This was successfully undertaken by Sandbergs over three visits to our factory.
Green solutions
At The Fitzrovia, material usage was instrumental in identifying opportunities to reduce carbon emissions.
Peikko’s DELTABEAM® Green was chosen as the logical replacement for the previous bespoke solution, as the client aimed to reduce their environmental impact. The carbon footprint of DELTABEAM® Green is approximately 50% smaller compared to conventional steel structures. Following a more environmentally friendly operating model, more than 90% of the material is recycled, the production uses electricity generated with renewable resources, and transportation is environmentally sustainable.
PCE also introduced cement replacers and a basalt crack control mesh instead of the more traditional steel mesh, which enabled the building to achieve a saving of approximately 292 tonnes of carbon dioxide equivalent over the original scheme. The building also achieved Building Research Establishment Environmental Assessment Methodology Outstanding and a 5-Star National Australian Built Environment Rating System (NABERS) rating.
"Working on The Fitzrovia project has been a fantastic experience. We designed DELTABEAM®s for all six floors, incorporating pre-welded channels and supports for the facade to streamline installation. With up to 120 minutes of fire resistance and slim-floor solution across every level, we made the most of what DELTABEAM®s have to offer. Collaborating with PCE on this project was a pleasure", concludes Mabast Ali, Peikko’s Structural Engineer.
Ease of logistics
Being a site in central London, logistics were also a key metric; the site is bordered on all four sides by public roads, none of which were allowed to have a permanent closure for offloading.
One road was subject to temporary closure when deliveries to site were made. Given the circumstances, the DfMA approach came into its own as the building was distilled down into the kit of parts. The kit of parts is comprised of a common set of hybrid components, meticulously manufactured offsite under strict factory conditions. The Ynomia electronic tagging system was also used on the scheme. This innovative solution allows for real time tracking in the BIM model of all the components during their manufacture & delivery. The benefits of this modular approach are substantial: reduced waste, on time deliveries, improved quality, and a significant boost to safety by reducing onsite operations. This has a significant impact by lessening local disturbances. This ensures a reliable, efficient, and environmentally friendly design, manufacture, and build solution.
Thanks to this innovative approach to construction, the structures were completed in 26 weeks.
