制造方法、施工设备、信息技术工具和项目交付系统的最新进展导致预制和模块化的使用增加。这项研究确定了关键因素和限制，可以帮助设计师，工程师和施工人员在商业建筑项目中选择模块化建筑而不是传统的“棒建”技术。选择一种施工方法而不是另一种施工方法的决策过程是复杂的，并基于许多因素，其中一些因素是现场条件，熟练劳动力的可用性，运输条件，组织准备，当地法规，项目进度和预算，可持续性要求和设计复杂性。本研究的目的是确定最关键的因素和限制，必须考虑的决策者选择模块化或坚持建立建设。本研究采用混合研究设计，分为三个阶段。在第一阶段，通过深入的文献回顾和六个行业专业人士的访谈，确定了97个决策因素和43个限制。在接下来的阶段，进行了问卷调查，以确定他们的定量评级和排名。在最后阶段，在五名模块化建筑专家组成的焦点小组的帮助下，十二个关键决策因素和六个主要限制因素被列入候选名单并得到验证。我们希望研究结果将有助于建筑，工程和建筑（AEC）行业在选择适当的建筑方法方面做出明智的决定。
Recent advances in manufacturing methods, construction equipment, information technology tools, and project delivery systems have resulted in increased use of prefabrication and modularization. This research study identifies critical factors and constraints that can help designers, engineers, and constructors in selecting modular construction over the conventional “stick-built” technique for commercial building projects. The decision-making process of selecting one construction method over another is complex and based on a number of factors, some of which are site conditions, skilled labor availability, transportation conditions, organizational readiness, local codes, project schedule and budget, sustainability requirements, and design complexity. The aim of this study is to identify the most critical factors and constraints that must be considered by the decision-makers for selecting modular or stick-built construction. The study employed a mixed methods research design and was divided into three phases. In the first phase, through an in-depth literature review and interviews with six industry professionals, ninety seven decision-making factors and forty three constraints were identified. In the following phase, a questionnaire survey was conducted to determine their quantitative ratings and rakings. In the final phase, with the help of a focus group of five modular construction experts, twelve critical decision-making factors and six major constraints were shortlisted and validated. It is hoped that the findings will help the Architecture, Engineering and Construction (AEC) industry in making informed decisions about the appropriate construction method selection.
