Modern Methods of Construction for a Typical Underground Rail Station.

What would a Roman soldier in A.D 43, a builder during Japan’s 1603-1867 Edo period, and a designer taking on todays’ world housing crisis have in common? Modern Methods of Construction.

Whether used to assemble a fort on the grassy fields of Britain during The Roman Conquest, out of necessity to rebuild wooden houses across Japan after one of the Edo periods’ 43 devastating fires, or to design and deliver affordable homes in the future, Modern Methods of Construction (MMC) have been propelling the design and construction industry forward for centuries.

A.D 43 saw Roman soldiers assemble homemade forts on the grassy fields of Britain, while Japan’s 1603-1867 Edo period was plagued by so many fires and natural disasters that offsite techniques for the fast construction and repair of buildings became a necessity. Incredible buildings across the world like London’s re-sited Crystal Palace (1852–54), the masterfully executed Eiffel Tower (1887), and the milestone Sydney Opera house (1959) combine with these earlier examples to reveal offsite construction as a centuries-old force in the AEC industry.

On the rise: MMC today.

The methods of offsite construction used today – like prefabrication, modular design, preassembly, and Design for Manufacture and Assembly (DfMA) – all fall under todays’ definition of Modern Methods of Construction (MMC). MMC is also inclusive of near-site and on-site pre-manufacturing, process improvements and technology applications, encompassing many sophisticated practices that streamline how we approach built work.

The social, economic, and environmental benefits MMC delivers are unignorable. Considering that today’s ambitious global sustainability targets will not allow the wasteful behaviour of our past to continue1By blueprints like the UK’s Construction 2025 which includes a 33% reduction in initial and whole life cost of assets, 50% faster delivery and 50% lower greenhouse gas emissions, the Australian Institute of Architects Going Carbon Neutral campaign with encourages its 12,000+ members to sign the NoCo2 Certification Program Agreement with the Carbon Reduction Institute become carbon neutral. and the UN’s recent commitments from COP27 which reaffirmed commitment to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels, cut greenhouse gas emissions and adapt to the inevitable impacts of climate change, as well as boost the support of finance, technology and capacity building needed by developing countries., MMC is the right way forward because it reduces pollution, waste, and material use.

Economically, MMC delivers more for the same investment. The possibilities this opens up has wide appeal to the pockets and imaginations of investors, designers, and builders alike because the process delivers on consistency, easy maintenance, and dis-and re-assembly without adding exorbitant costs.  

Broader adoption of MMC also has the potential to widen our supply chains in ways that create possibility for smaller and minority-owned businesses. Local companies and jobs would benefit from this increased demand and agility – creating a scenario in which these companies could invest in the tools they need to continue to grow a fairer supply chain.  

MMC offers many social, economic, and environmental benefits.

Blueprints have emerged to address reducing the embodied carbon of construction, like the UK’s Construction 2025 which includes a 33% reduction in initial and whole life cost of assets, 50% faster delivery and 50% lower greenhouse gas emissions, the Australian Institute of Architects Going Carbon Neutral campaign which encourages its 12,000+ members to sign the NoCo2 Certification Program Agreement with the Carbon Reduction Institute to become carbon neutral. The UN’s recent commitments from COP27 also reaffirmed the need to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels, cut greenhouse gas emissions and adapt to the inevitable impacts of climate change, as well as boost the support of finance, technology and capacity building needed by developing countries.

MMC and Rail.

With the number of public transport users expected to reach 4,477.2m users by 20261Statista, ‘Public Transportation – Worldwide’, Aug 2022, accessed 9/11/2022. Available online. , the use of MMC in rail must rise. If the industry can harness the agility, consistency, and quality of these methods, then we can create safe, sustainable, and efficient stations that are just as beautiful and responsive to place as anything constructed completely onsite.

Train stations are well suited to MMC and already boast many pioneering examples. Brazil’s Estação da Luz (1901) was built in Glasgow, disassembled, and then reassembled in São Paulo (fig.4.1 and 4.2) and the Great Western Railway (1904) used simple, prefabricated ‘pagodas’ clad in corrugated iron to serve as shelters on lightly used stations across Britain.

MMC must become the norm in rail. Although broad adoption has been slow – due to perceived lack of maturity in the market2Abd Razak, M.I.; Khoiry, M.A.; Wan Badaruzzaman, W.H.; Hussain, A.H. DfMA for a Better Industrialised Building System. Buildings 2022, 12, 794. https:// doi.org/10.3390/buildings12060794 and historical concerns about limited flexibility, quality, supplier issues, and long lead time3Hinderance factors/Design Limitations, Abd Razak, M.I.; Khoiry, M.A.; Wan Badaruzzaman, W.H.; Hussain, A.H. DfMA for a Better Industrialised Building System. Buildings 2022, 12, 794. https:// doi.org/10.3390/buildings12060794 – hefty advancements mean we’re due to harness it. This can be approached in three ways:

  1. Early and equal commitment.
  2. Combine MMC with traditional construction methods.
  3. Using MMC elements to create narratives.

1. Commit early and equally.

The sheer scale of projects within the transport sector requires a substantial commitment to MMC from all parties from the project’s conception. Success requires expertise in procurement, a strong emphasis on BIM plans, commitment to an integrated digital model, and robust process management – all combined with a detailed and well communicated program that includes clear sequencing of information. Put simply, the entire project team needs to be in sync from the start.

Designed with John McAslan + Partners and Laing O’Rourke on behalf of Sydney Metro, Sydney’s Central Station used a direct approach to MMC within the project’s design methodology. This minimized on site construction, avoided disruption, improved safety for customers and builders, reduced waste and maintained better product and quality control. Contractually agreed on site ‘possession times’ for the install of major modifications or installations of MMC components in the live rail environment meant quick installation and minimal customer disruption. Safe and sustainable, this ‘all in’ approach saved time and was an intelligent use of financial, material, and social resources.

2. A balanced method.

Great design is empathetic, but a perceived problem with MMC is that the use of standardised parts denies a project the sense of identity that is required for an empathetic space. Rail stations are vital placemaking opportunities for cities and towns, required to foster connection, belonging and delight, and therefore the importance of identity in this sector cannot be overstated.

To remedy this de-characterisation designers and architects to be precise about where MMC processes are employed. Beyond the parts that commuters use, train stations have an astonishing amount of unseen infrastructure that can deeply benefit from the consistency, flexibility, and easy maintenance provided by MMC. In every rail project, there’s ample room for customisation and standardisation – and no need to sacrifice the gains of either.

To deliver the best experience for commuters and locals, Sydney Metro’s Crows Nest Station needed a unique identity and a design that could be easily maintained, repaired, and upgraded over its lifetime. These needs were met with a balance of MMC and traditional methods.

MMC was employed at Crows Nest for the stations’ precast concrete beams, some of which weigh upwards of 65 tonnes, that were fabricated offsite and installed via crane. This made construction safer, more sustainable and cost effective by reducing the need for propping and formwork and decreasing material waste. The beams and other MMC elements can be easily replaced and quickly repaired, reducing the risk of excessive station shut-down periods and allowing commutes to go uninterrupted.

Crows Nest demonstrates how MMC can be used the foundation of a project without detracting from the design techniques that establish identity. The MMC elements of the station are woven with traditionally constructed elements, exposed brickwork and tessellated tiling, to create a unique sense of place that draws on the areas’ historic architecture.

Based on Maslow’s Hierarchy of needs, the Hierarchy of Space and Experience was developed by Woods Bagot and ERA-co to provide scope to enquire into how Sydney Metro commuters experience Metro environments now and could experience Metro environments in the future.

3. Creating a visual narrative.

As well as being used for elements that are inconspicuous to the public, MMC can also be used to create a cohesive visual language for commuters. Done mindfully, the repeated use of recognisable MMC materials and elements can impart a sense of belonging.

Crows Nest Station reinforces its identity with MMC via the use and arrangement of prefabricated hybrid elements including precast concrete and brick cladding modules, steel and brick facades systems, modular steel cladding arrangements and exposed precast structural elements – building a recognisable spatial narrative that celebrates the intersection of infrastructure and community (Fig. 9.1 and 9.2). Similarly, Sydney Metro Central Station uses MMC elements like engineered sandstone (GRC) panelling, lift structures, roof cassettes, and precast brick art panels work to create a sense of familiarity.

These cost-effective and beautiful ‘kits’ of recognisable MMC elements demonstrate how stations can optimise the use of MMC to create a clear visual narrative across the user journey. They can also be easily dis- and re-assembled for repair or reuse.

An MMC future.  

Increasing the use of MMC in rail today will improve our tomorrow. Rather than being in opposition, a human-centred design approach requires the industry to commit to harnessing MMC for a safer, fairer, and more sustainable future.
