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.
