Construction firms are squeezing out a little more cash on technology investments, but many still cling to the use of spreadsheets for project management, a new survey says.

Technology consultancy JBKnowledge queried over 1,000 construction firms of all sizes about their technology investments for the 2014 survey, which it will release in full in early December. The respondents included engineers, estimators, C-level executives and project managers; 74% of all the respondents identified commercial construction as their main business, with every discipline, such as civil, federal and highway construction, also represented.

总部位于达拉斯公司总裁詹姆斯·本纳姆（James Benham）说：“我们真的很高兴看到使用比近年来更多的技术。”他补充说：“我们在今年的结果中看到了用于航空摄影和摄影测量法的3D打印和四轮驱动器利用的广泛采用。“我们看到承包商以他们从未有过的方式尝试技术。”现场数据进入，通过从基于纸张的现场数据使用转移的公司继续迅速上升。结果表明，企业正在使用RFID跟踪系统，3D打印和增加激光扫描的使用，仅举几例投资。。Microsoft Excel和电子表格是公司用于项目管理的几乎所有软件的问题的最佳答案。Benham补充说，尽管对于许多任务，但对于项目管理和时间表来说，Excel被“严重过度充足”。“它没有[其他]构建项目软件所内置的情报。因此，这是一个非常重要的抑制剂。”

Other industries spend about 6% to 8% of their revenues on IT investments, while construction is still in the 1% to 2% range, Benham notes. "If there's one major takeaway, it's that we don't spend enough money on tech."
