reports the following metrics that demonstrate the benefits of a Platform approach: n A 19.4% reduction in embodied carbon per square metre (36.4% carbon reduction in the substructure, and 20.2% in the superstructure and façade);
n A 35% reduction in labour (including a 50% reduction for superstructure and facade);
n Use of automation in assembling the superstructure, eliminating all work at height (which will facilitate use of lower skilled, highly productive, labour);
n A 9.5% saving in capital cost. n A 2% increase in nett lettable area.
The adoption of Platforms marks a new strategy for UK government. Rather than focus on individual projects or programmes, it seeks to leverage the scale of the public sector portfolio to create a transformational shift. The key is to establish widespread adoption. This will unlock the greatest benefit for the industry as a whole. The Construction Playbook states: ‘We will look to procure construction projects based on product platforms comprising of standardised and interoperable components and assemblies, the requirements for which will be part of a digital component catalogue. Contracting authorities should collaborate to find opportunities not only for their own platform solutions but also for ways in which cross-sector platform solutions, can be applied, for example, by using platforms that enable interoperability of components across different sectors.’
The Construction Innovation Hub To accelerate the adoption of Platforms, the government set up the Construction Innovation Hub (‘the Hub’), of which I am the Design lead. The Hub brings together
