Two major supply chain companies (Algeco and The McAvoy Group) collaborated in the project to use the same design rather than their non-identical competing versions. This has delivered benefits in cost and time for both companies but also their supply chain who were providing two different sets of components for the same end use.
Through working with the Seismic II consortium, Tata Steel UK have developed their own complete building system compatible with the Seismic frame and modern methods of construction.
This building system consists of floor cassette, ceiling cassette, internal / external wall system including internal liner and cladding that are focused on reducing module assembly time for manufacturers as well as being a pre-assembled kit of parts, for assembly directly on site.
In addition to this Tata Steel have developed drop-on roof cassettes that are designed to enable modular manufacturers to deliver a complete system with less time and effort.
The use of the same frame design in the supply chain, rather than non-identical competing versions, allowed for faster assembly and less weight - both of which reduced costs throughout the supply chain.
SEISMIC allows for construction with a 70% lower carbon impact, both embodied and operational (benchmarked against Construction 2025 targets). The use of a modular frame design and light-weight materials reduces the amount of steel normally used in an average primary school, built offsite, by 25%. This in turn reduces the emissions associated with transport and steel by 25% – the equivalent to over 155,000 miles of car travel, or 17 flights from London to Sydney. Analysis shows that a standard Seismic module comprises 581.3 kgCO2e per m2, well below Construction 2025’s target of 1,300 kgCO2e per m2. And, because Seismic can be reused, either by relocating modules to other sites or by refurbishing individual components and cassettes, it adds a 234 kgCO2e per m2 clawback. This brings Seismic well beyond even the lowest stretch targets being discussed in construction today.
Collaborative working, a modular design, a frame built offsite, and more efficient supply chain processes led to a 52% reduction in build time, creating a more efficient, productive process. SEISMIC is capable of delivering a building that is 75% faster to complete, exceeding the government’s Construction 2025 targets.
Modern Methods of Construction (MMC) offer a huge opportunity to reskill the existing labour workforce and bring new people into the industry. As well as addressing a wider skills shortage, it should help to increase the diversity of the workforce too.
At scale, a rolling programme can be managed with factories working at capacity to build modules that are suitable for any project of that kind. And, because Seismic is a platform-based approach this can be done across industry, with multiple manufacturers.
With so much of the build taking place in factory, there are fewer chances for injuries on site. The reduction in health and safety incidents is estimated at 80%.
The digital tool developed means designs for schools can now take minutes rather than weeks, which saves on development costs and time. The redesigned frame could be erected more quickly, showing a 52% reduction in assembly time. Because site preparation works take place in parallel with the manufacturing process SEISMIC is capable of delivering a building that is 75% faster to complete, exceeding the government’s Construction 2025 targets.
Because Seismic is a component-based system built on a standard frame, modules are easy to adapt throughout the lifecycle of the building. Components can also be recycled and used for other projects in the future.
Every component is tracked, tagged, and linked to a 3D model, allowing for a fully traceable process for every component that goes into a module. This aligns with the Hackitt Report recommendations for a digital 'golden thread', making it safer and easier to maintain a building. It also makes it easier to keep track of components and reuse them for other projects.
