       McGraw-Hill最新发布的SmartMarket报告——“The Business Value of BIM in North America: Multi-Year Trend Analysis and User Ratings (2007–2012)”显示，北美地区的BIM采用从2007年的17%上升到2012年的70%。
       McGraw-Hill Construction 公司的高级主管Stephen Jones先生说：“尽管在最近经济萧条的大环境情况下增加投入看起来不太合理，但是该报告确实表明，建筑行业正在持续对BIM技术进行投入，因为BIM技术将给行业带来一个更加高效的未来。”
       欧特克公司副总裁Phil Bernstein先生说：“该报告的调研结果证实了一些在北美大家都看得到的趋势，尤其是BIM在建筑行业业主、建筑师和工程师中越来越广泛的应用。BIM所带来的各种商业价值，如图纸质量的提供、重复劳动的减少、项目工期的缩短、更好都服务等等，得到广泛认可。”
    该报告显示，业主正成为采用BIM的主要推动力。HOK公司CEO、buildingSMART国际协会主席Patrick MacLeamy先生预测：“接下去的10年中，业主将越来越多的将采用BIM技术作为建筑项目开展的前提条件，将建筑业推向一个追求精确性、高质量和高效率的新纪元。”
    为了量化用户使用BIM的程度，McGraw-Hill Construction 公司提出了BIM投入系数（BIM Engagement Index）。该系数值从BIM用户的技能水平、从事BIM的时间、以及采用BIM项目所占比率等计算得来。该报告显示，13%的BIM用户有很高的BIM投入系数得分（即有熟练的BIM技能、5年以上的BIM经验，60%以上的参与项目使用BIM）。在这部分BIM用户中，67%认为BIM的投资收益率率（ROI）很高。
      BIM在几年前还只是少数先驱者采用的新技术，现在已经成为了北美建筑行业的主流。McGraw-Hill公司的SmartMarket系列报告“the Business Value of BIM”为行业提供了BIM在行业的发展情况、投资回报情况等重要信息。

BIM Adoption Expands from 17% in 2007 to over 70% in 2012: McGraw-Hill
February 4, 2013 by Editor BIM Journal
 A new McGraw-Hill Construction Report has said that the adoption of BIM has expanded from 17 per cent in 2007 to 71 per cent in 2012. According to its latest SmartMarket Report, “The Business Value of BIM in North America: Multi-Year Trend Analysis and User Ratings (2007–2012), BIM adoption has expanded despite the recent economic pressures.
“Though it may seem counterintuitive to increase spending during a recession, the research indicates that the industry is continuing to invest in a more efficient and productive future by embracing technologies and processes of BIM,” said Stephen Jones, a senior director at McGraw-Hill Construction, a financial intelligence and education company.
“The results of the survey validate many key trends we are seeing in North America — notably, the strong growth of BIM in construction and adoption amongst owners, architects and engineers,” said Phil Bernstein, vice president, strategic industry relations at Autodesk. “The results also point to the increased business benefits that all users derived from using BIM, such as better profits, more accurate documentation, less rework, reduced project duration, fewer claims and the ability to offer new services.”
The report states that owners are becoming an important driving force to this increased adoption. Patrick MacLeamy, CEO of HOK and chairman of buildingSMART International, predicted, “Over the next ten years, building owners will demand ever-increasing usage of BIM as a precondition, ushering in a new era of accuracy, quality and sophistication for the building industry.”
As a way to quantify users’ level of commitment to BIM, McGraw-Hill Construction developed a BIM Engagement Index, calculated from each BIM user’s skill level, years of BIM experience, and percentage their projects that use BIM. McGraw-Hill Construction found that: 13% of BIM users demonstrate a very high BIM engagement level (e-level), requiring expert skill level, five or more years of experience, and implementation of BIM on more than 60% of their projects.
 67% of the very high e-level users report a very positive ROI on BIM (25% or higher) versus only 20% of low e-level BIM users, two-thirds of whom are at negative of break-even ROI.52% of very high e-level users experience increased profits from their use of BIM compared to the 36% average for all users.
BIM, an innovative approach to design and construction for pioneering early adopters just a few years ago, is now taking its place firmly in the mainstream of the North American construction industry. “McGraw-Hill’s SmartMarket Report series on the Business Value of BIM has provided the industry with relevant research and metrics on BIM adoption and return on investment,” said Mike Ozatalar, vice president and manager of Engineering, Parsons. “Parsons is proud to be a sponsor of this report and continues to provide contributions in the engineering and construction industry in BIM and integrated design and delivery solutions.”
