Could platform construction offer a more controlled route to compliance?
The industry has spent years discussing platform construction in terms of speed, productivity and cost. The Building Safety Act changes the conversation, says James Cowell – UK Technical Director from Algeco. In a regulatory environment that increasingly demands traceability, accountability and a robust golden thread of information, the strongest argument for platform construction may be its ability to create repeatable, auditable and verifiable processes.
The Building Safety Act (BSA) is changing the way the construction industry thinks about accountability. The emphasis is increasingly on demonstrating that the right decisions have been made, the right products have been used and that there is a reliable record of how a building has been designed, constructed and maintained.
That presents an interesting challenge for an industry accustomed to treating every building as a unique project. Instead, a more standardised, platform-based approach could provide greater consistency, while still allowing buildings to respond to their location, function and users.
Consistency starts before the building reaches site
Platform construction applies the principles of standardisation to building systems, components and processes. Elements can be designed and engineered as part of a repeatable system, then configured to meet individual project requirements. There is then less need to reinvent solutions on every project
The Product Platform Rulebook developed by the Construction Innovation Hub is an open-access guide to support industry – clients, consultants, contractors, manufacturers and product suppliers – to harmonise requirements and specify a platform approach with confidence; secure in the knowledge that it will improve safety, performance, and quality.
Accuracy built into the process
An established system provides greater certainty around how components fit together, how they are manufactured and how they will ultimately be assembled. This becomes particularly valuable where buildings must meet demanding technical and operational requirements. Standardised elements can be designed and manufactured in a controlled environment, with established processes and quality checks applied before they reach site.
The value is not simply manufacturing away from site. It is establishing a repeatable system that can be applied and refined across projects.
Reducing the opportunity for error
Moving more of the construction process into a controlled manufacturing environment can also reduce the amount of work carried out in variable site conditions.
Components can be manufactured, checked and inspected before they arrive on site, reducing activities that need to be completed under time pressure or alongside multiple trades. Repetition also allows processes to be refined. Successful details and manufacturing methods can be carried forward rather than treated as new problems on every project.
For contractors and clients, this has the potential to translate into fewer defects, less rework and greater predictability during installation.
A clearer record from design to delivery and beyond
The principles of standardisation and controlled manufacture can also support the need for greater control of information and clearer evidence of how decisions have been implemented. Quality and traceability can become part of the process from the outset rather than information assembled retrospectively at the end of a project.
Digital information can also support this process, creating and maintaining an accurate record alongside the physical components. The aim is a joined-up relationship between design intent, manufacture, assembly and verification, supporting the requirement for reliable information throughout the building lifecycle.
Learning from one project to the next
Repeatability also creates an opportunity to learn. Traditional construction can make it difficult to carry knowledge between projects as teams and supply chains change.
A platform approach creates greater scope to refine the system over time. Manufacturing processes can be reviewed, installation methods improved and lessons from previous projects incorporated into subsequent designs.
For clients delivering programmes of similar buildings, this is particularly valuable. Justice, defence, education, healthcare and other sectors with recurring requirements can adapt established solutions rather than developing them from scratch.
It could also help address skills shortages. Moving repeatable activities into a controlled manufacturing environment can make processes easier to train for and replicate, while specialist skills can be focused where they add greatest value.
Standardise the system, not the building
The opportunity is not to eliminate bespoke design, but to reconsider where it adds genuine value. If underlying structures, interfaces and manufacturing processes can be standardised, design effort can focus on what makes each project unique and adds genuine value to the end user. This reduces the design cost and programme and allows more focus on the subtle design details pertinent to the project - the site, users, performance requirements and operational needs.
A common system, interface, component or manufacturing process can provide a consistent foundation, while layouts, finishes and configurations are adapted as required. This balance between repeatability and flexibility is central to platform construction.
One example is the Seismic Platform, which was specified for Northampton School for Boys. Algeco was appointed principal design & build contractor for the project and worked with Watson Batty Architects to provide a full turnkey solution.
The system was originally developed through the Seismic consortium, with Algeco playing a leading role alongside a range of industry and academic partners. A patented universal corner connector enhances the horizontal and vertical interconnectivity of the structural modular system. This enables the componentisation and standardisation of the floor, ceiling, roof, internal wall and building envelope systems, which then integrate simply with the Seismic frame. Clients or suppliers can develop and add their own specification of components beyond a standardised Option 1 or 2, to suit their requirements and meet with changing regulations.
The platform-based approach was selected because of its potential to accelerate delivery, improve value and provide greater consistency, quality assurance and predictability than traditional construction approaches. Whilst Algeco’s offsite team prepared the foundations, 210 modules were manufactured at the firm’s East Yorkshire facility, which also added significant savings on the overall construction schedule.
Where there is scope for repeatable building types, a platform approach offers an opportunity to move away from continually reinventing the wheel. The real shift is cultural as much as technical: considering what can be standardised, improved and repeated.
For an industry under pressure to build more while demonstrating that it has built safely and correctly, could this be the most compelling arguments for taking a platform approach?
