这篇研究是关于BIM应用对建筑项目的影响评估。这份调查主要探讨BIIM应用过程中对建设项目的影响的六大主要指标。它们包括：质量控制、进度控制、造价、安全性、 dollars/unit (square feet) performed, 以及units (square feet) per man hour等。研究数据来自一份以上述六个指标为核心的，针对BIM项目从业者的调查报告。被调查者主要为美国NBIMS委员会的成员。通过作者做的调查显示，BIM项目从业者普遍认为BIM的应用对上述建筑项目的六项指标有积极作用，尤其是在质量控制、进度控制和units per man hour三个指标上。同时，低于一半（46%）的被调查者认为BIM应用对建造安全性有所提高。

evalUATING THE IMPACT OF BUILDING INFORMATION MODELING (BIM) ON ConSTRUCTION
Patrick C. Suermann, Raja R.A.
【摘要】: This research assessed perceptions about the impact of the implementation of Building Information Modeling (BIM) on construction projects. Survey questions centered on impact with respect to six primary construction key performance indicators (KPIs) commonly used in the construction industry as accepted metrics for assessing job performance. These include: quality control (rework), on-time completion, cost, safety (lost man-hours), dollars/unit (square feet) performed, and units (square feet) per man hour. Qualitative data was collected through a survey instrument intended to assess practitioners’ perceptions about BIM impacts on the six Key Performance Indicators. The survey was targeted at National Institute of Building Sciences (NIBS) Facility Information Council (FIC) National BIM Standard (NBIMS) committee members. The survey, with a response rate of 50 completed surveys, showed preliminary results indicating that the NIBS FIC NBIMS members felt that a BIM-based approach improves construction metrics compared to construction without BIM. Specifically, the highest three ranking KPIs in order of most favorable responses were quality, on time completion, and units per man hour. The second tier of favorable responses included overall cost and cost per unit. Finally, only 46%, or less than half, of the respondents thought that construction safety was improved through BIM.
