Multiplex is undertaking a significant refurbishment of London’s IBM Building, retaining most of its original structure.
- The project includes extensive remodelling, with a focus on sustainability and added space.
- Key construction activities are happening in stages, with an aim for completion by the end of 2024.
- The endeavor seeks to enhance both the building’s practical functionality and its green credentials.
- Advanced techniques and materials, including prefabrication and recycled steel, are crucial in this transformation.
The IBM Building in London’s South Bank, a prime example of brutalist architecture, undergoes a major transformation under the hands of construction firm Multiplex. This refurbishment retains 80% of the existing structure, focusing on eco-friendly practices while adding around 11,000 square metres of new floorspace.
Multiplex is enhancing the building’s sustainability through several innovative strategies. Aiming for top environmental and wellbeing ratings, they are utilizing BREEAM standards and the WELL v2 rating, while retaining the original concrete to minimize CO2 emissions. The project uses ground granulated blast slag (GGBS) to replace a significant portion of cement, further lowering the carbon footprint.
The construction timeline is well-organized, with major milestones being meticulously planned and executed. From the strategic demolition by Keltbray to prefabrication work, the project faces challenges due to the site’s location and stringent requirements due to its Grade II-listed status. The use of reusable materials, like reclaimed steel, is central to the project’s environmental goals.
Advanced construction techniques are in play to manage this complex refurbishment. Prefabricated elements, like washroom pods and risers, are utilized to streamline installation and reduce on-site risks. Innovative approaches also contribute to a significant reduction in carbon emissions, such as the painstaking process of hand-setting aggregate panels to match original aesthetics.
The project’s end goal is not only to revitalize the building’s architectural grandeur but also to embed modern efficiencies and environmental considerations into its structure. The phased construction plan ensures minimal disruption to the surrounding cultural landmarks, like the nearby National Theatre, with measures to reduce noise during performances.
The refurbishment of London’s IBM Building exemplifies a careful blend of preserving architectural heritage while meeting modern sustainability needs.
