BARRIERS TO USE
Procurement
Traditional approach Alignment to MMC
Procurement carried out post planning Early engagement in design process
Single point of warranty provision Suitability to sub-contracting model
Public sector minimum procurement thresholds Ability to tender through OJEU and frameworks
Fixed price contract Requires detailed design and specification
Decision making weighted to lowest price Not necessarily cheaper from a capex perspective
Delays to contract award Factory overheads without any ‘filler’
Contract and allow design flexibility Early design freeze
Funding and Mortgagability
Target launch: Q1 2019
Joint working group with lenders, valuers and the industry to ensure mortgages and building insurance are readily available
across a range of tested MMC.To develop a ‘MMC Scheme’ that will become the minimum benchmark to be able to access mortgage finance and normal
insurance policies.
Design standardisation and rationalisation
Offsite manufacturing design code to Design for Manufacturing and Assembly approach at early site development stage.
Ensure that manufacturer parametric design rules are reflected in the tool.
Client concerns around bespoke systems.Wider stakeholder concerns around uniformity.
Demonstrating social value
‘Social value’ association with using local labour through S106
SMEs
Mayor Construction Academy Scheme
Careers Advice
Local community events
Onsite digital skills
