Projecting at the project level: MMC supply chain integration roadmap for small housebuilders

Abstract

Purpose

This paper aims to provide insights into how supply chain integration may occur for small housebuilders adopting modern methods of construction (MMCs). The process of creating an empirically informed road map is described, whereby the practical day-to-day challenges of adopting a timber-frame solution on a small housing development in Southeast England were fed into a road map of future supply chain integration scenarios. The intention is to better position small housebuilders to contribute in addressing the shortfall in housing that continues to face the UK.

Design/methodology/approach

Interviews with supply chain members along with on-site observations captured key aspects of integration. Findings were used within two collaborative forums to guide discussion in a dual approach; discussing the challenges of timber-frame on the project and what would be needed on future projects for the firms analysed.

Findings

Empirically informed malleable roadmaps, of the kind developed within this study, provide feasible options for small housebuilders and suppliers of MMCs to collectively collaborate when transitioning towards fully integrated supply chains. Practically, the roadmapping approach, and the roadmap itself, would help small housebuilders and suppliers of MMCs transition towards full integration. Opening up avenues of integration that are spread across yet connected through numerous phases, firms and technologies helps construction professionals use more sophisticated modular and volumetric off-site solutions.

Research limitations/implications

Data collection took place over the course of a year. Future research could expand this relatively short duration to analyse the potential for construction professionals within the supply chain to integrate further over a longer period of time.

Originality/value

The novelty and contribution of this paper lie in the development and application of an alternative approach to roadmapping that departs from the normative linear examples of roadmaps found within the technology-roadmapping literature. The authors present a structured yet flexible approach to roadmapping that is both representative of the strategic planning and innovation activities that occur within small housebuilding firms and open to adaption to account for firm-level characteristics and contingencies. Positioned alongside firm-level dynamics (e.g. business cases and approaches to design), the roadmapping approach also reinforces the potential of incremental rather than whole-scale transitions.
