Abstract
Modularization has recently attracted considerable interest among academics and practitioners. In the construction industry, several modular solutions have been introduced and examined; however, hardly any study comprehensively classifies the different modularization strategies according to their possibility to achieve various objectives of building investments. This research aims to develop a framework for identifying and classifying modularization strategies in construction according to their suitability to achieve the specific outcomes intended for a building or its subsystem. Using the literature on product modularity, product platforms and production strategies as a basis, this study has developed a theoretical framework that proposes connections between the main objectives of a building investment and the dimensions of modularization strategies. The framework is elaborated by testing the propositions, based on an empirical analysis of nine real-life case studies. The findings reveal that modularization can be a suitable approach to develop an innovative design solution; improve a project’s quality, cost and schedule performance; and enable flexibility in building use and maintenance. However, suggestions for achieving these objectives vary from project organization-driven to collaborative, integrated or supplier-driven modularization strategies. Developers, owners, contractors and module suppliers can use the framework when positioning and developing their roles in the construction supply chain.
