Sector must advance digital technology
A roundtable on ‘Construction’s Digital Future’ has said that UK building professionals should take a leaf out of motor racing’s book in order to advance their use of digital technology. The Westminster Sustainable Business Forum (WSBF) event, sponsored by the British Board of Agrément and chaired by Housing, Communities and Local Government committee member Teresa Pearce MP, discussed how the construction industry ‘lagged behind’ others with similar levels of complexity in the uptake of digital technology. It discussed how embracing digital technology delivers secondary benefits including more efficient use of materials, better labour organisation, improved health and safety, waste reduction and safer working environments. Attendees suggested that construction looks to sectors such as motor racing and aerospace which have widely embraced digital models and virtual testing because the costs, safety implications and reputational

impact mean that they have to. “There is little doubt that digitalisation holds the key to helping solve many challenges for the construction industry,” said Wendy Ajuwon, BBA head of marketing. “We are really keen to facilitate debate and push this agenda, not least because developing this technology for our industry can help deliver the Hackitt Report’s all-important ‘golden thread’ of quality building information.” Andrew de Silva, a director at Andrew Miller Architects, said although there were many reasons for the limited uptake of digital technology, it was primarily due to complexity; projects operated on a variety of scales and required a range of skills and abilities across sectors. The situation was further hampered by industry fragmentation and competing priorities from different stakeholders with different procurement routes. “It’s important that the right data is given to the right people at the right time and that’s a key element of the process,” said De Silva, who believes BIM should be at the core of businesses and not just an ‘added service’. During discussions around the use of BIM, attendees gave consideration to making BIM Level 2 mandatory at tender stage on residential projects utilising off-site construction techniques which lend themselves well to digital workflows.

Timber buildings to feature in Toyota’s prototype city of the future Toyota has revealed plans to build a prototype “city” of the future on a 175-acre site at the base of Mount Fuji in Japan. Announced at CES 2020, the global consumer technology show in Las Vegas, the Woven City will be a fully connected ecosystem, powered by hydrogen fuel cells. Envisioned as a “living laboratory,” the city will be home to full-time residents and researchers who will be able to test and develop technologies such as autonomy, robotics, personal mobility, smart homes and artificial intelligence in a real-world environment. Akio Toyoda, Toyota Motor Corporation president, said: “Building a complete city from the ground up, even on a small scale like this, is a unique opportunity to develop future technologies, including a digital operating system for the infrastructure. With people, buildings and vehicles all connected and communicating with each other through data and sensors, we will be able to test connected AI technology, in both the virtual and

Looking to the future The benefits of timber buildings are plentiful, from improved embodied energy due to them acting as a carbon sink, to cleaner, safer, quieter building sites and the positive impact that it has on people’s wellbeing. “We’re delighted that more and more clients are seeing the broad benefits of using timber, whether environmental or in terms of staff/ student/visitor/user wellbeing,” said Fowles. And as tackling climate change moves higher up the political agenda, we are sure to see many more high-profile commercial buildings being constructed from timber.

White Arkitekter is continuing to promote timber in all of its structures and to extoll the benefits of working with the material. “Right now, timber is the only renewable building material there is, and it is a fantastic material to work with,” said Schmitz.

Demand from the market is also encouraging councils to open up their doors to modular.

FEATURE: OFF-SITE CONSTRUCTION panels. These can allow super-insulated, low energy ‘passive’ buildings to be constructed using renewable, locally sourced, carbon sequestering materials, ensuring that buildings can be constructed to meet the demanding PassivHaus specification, with resultant almost zero heat requirements, saving money and CO2 emissions. The firm has used foam tapes in several projects to provide airtight, acoustic and thermal interior and exterior seals between prefabricated panels, which are then used in offsite construction. Sustainability was a key driver for the project: ModCell panels were used to build the super-insulated structure to the highest ecological standards using thermally efficient, 48cm thick, prefabricated straw bale wall panels, with tapes filling the 10mm expansion joints between panels and around windows and doors. This helped to achieve an excellent target of <2.0 m³/hour/m² measured at 50 Pascals airtight seal for the complete building – a good standard for the construction industry is anything between 3 – 5 m³/hour/m².

IS AN EXCELLENT CHOICE FOR ANY GREEN BUILDING PROJECT
Using wood products from responsibly managed forests is key to any green building project. Third-party forest certification standards, like the Sustainable Forestry Initiative® (SFI), are a proof-point that wood comes from responsibly managed forests that have been managed for multiple environmental, social and economic values — today and into the future. Architects and builders are turning to products certified to the SFI Standard to meet their green building needs. Learn more at sfiprogram.org/green-building.
Products certified to SFI are recognized by many leading green building rating programs around the world like the Building Research Establishment Environmental Assessment Method (BREEAM and the Leadership in Energy and Environmental Design (LEED).

New lease of life Kebony cladding has been used to give a modern twist to the extension of a once traditional 20th century home in Dorking, deep in the Surrey Hills. Juxtaposed against the original building Lees Munday Architects selected Kebony to achieve the owner’s vision for a sustainable and family friendly home. Improving the existing kitchen positioned on the east side of the house, with no garden access, was a key priority for the architects, who were able to rework the kitchen, dining and daytime seating area to provide an open plan functional living space which embraces the sunny western aspect of the house and takes advantage of the large rear garden and spectacular view. The adjacent lounge was significantly enlarged and continued the

Kebony cladding along the rear elevation of the house. For Lees Munday Architects, a relationship with the garden and the landscape was an essential focus throughout the design. As a result, two sides of the new extension, and the lounge, were completely glazed to incorporate the garden as part of the interior living space, whilst bespoke sliding doors opening onto a paved patio for alfresco dining and children’s play were also installed. A loft conversion has provided an extra en-suite bedroom, while the master bedroom has gained a full height window and roof terrace, both taking full advantage of the spectacular far-reaching views.

The simple geometry of the twin-hipped roofs breaks up the bulk seen from outside and defines the different spaces internally without a physical division. The timber Kebony cladding lines up across the walls and roof, with compound mitred joints, making the whole extension appear to be carved from one block of wood, with no visible gutters to compromise the sharp lines. “Following our appointment for this project, it was essential that the family felt they had made the right decision in opting for an extension rather than moving house,” said Marty McColl, director at Up Architects. “We were able to create substantially more space, whilst ensuring the extension reflected the brief to build something that was beautiful in design without being ostentatious; we are thrilled with the final product and loved working with Kebony to transform
