Construction industry players are now realising the need to implement Building Information Modeling (BIM) at the preconstruction planning stage to allow spatial data of the site to be incorporated into the BIM. Incorporating spatial data in BIM as early as possible in the building lifecycle poses a new challenge to industry players, particularly to the consultants who collect and provide these data. The aim of this study is to identify important factors for incorporating spatial data into the BIM at the preconstruction planning stage. Three rounds of the Delphi method were employed to obtain a consensus among twenty construction industry experts, selected through purposeful sampling. The findings revealed seven consolidated factors, with Technology, Client Demand, and Added Value as the top three, followed by Regulations, Skilled Staff, Management Commitment and Data Management. Experts were significantly in agreement with each other, as indicated by the Kendall’s W Coefficient = 0.6505 significant at < 0.005. The findings highlight the requirements for utilizing spatial data in the BIM at the preconstruction planning stage and help the respective professional bodies to identify the prerequisites for BIM application and subsequently, improve the existing training for the professional development of their members.

确定使用Delphi方法将空间数据合并到BIM中的因素

建筑行业参与者现在意识到在施工前规划阶段需要实施建筑信息模型（BIM），以便将场地的空间数据整合到BIM中。尽早在建筑生命周期中将空间数据整合到BIM中，这对行业参与者，尤其是收集和提供这些数据的顾问，构成了新的挑战。这项研究的目的是在施工前规划阶段确定将空间数据纳入BIM的重要因素。通过有目的的抽样选择了三轮Delphi方法，以获取二十位建筑行业专家的共识。调查结果揭示了七个综合因素，其中技术，客户需求和附加值是前三个因素，其次是法规，技术人员，管理承诺和数据管理。专家之间的观点彼此一致，如肯德尔的W系数= 0.6505（<0.005时显着）所示。调查结果突出了在施工前规划阶段在BIM中利用空间数据的要求，并帮助各个专业机构确定BIM应用的先决条件，并随后改善其成员职业发展的现有培训。
