It's time for public agencies to embrace the shift to digital construction project delivery, David Unkefer, senior construction engineer at the Federal Highway Administration, told construction sector professionals at ENR's FutureTech conference on June 9.

His agency is looking to go fully digital for greater productivity in project delivery and asset management, and welcomes use of alternative contracting methods that integrate design and build and allow for post-construction data management, he said—highlighting its support of an initiative to adopt proven technologies such as e-tickets and digital as-builts and building a pooled database to create GIS data for use on projects.

犹他州运输部的州设计和标准工程师乔治·卢克斯（George Lukes）表示：“我们最终希望创建一个使用2D高架视图，该工作流程与3D数据集成在一起。”这位高级项目高管表示，许多运输工程师和承包商都在尝试使用下一代BIM工具，这些工具仍未完全满足运输需求，以及在最近使用无人机和激光雷达的数量计算和现场数量的缺点和现场数量的缺点达到数据传输的统一标准。

新利18备用Enr的第17届FutureTech是旧金山举行的为期三天的建筑技术演示和网络活动，于6月10日结束，重点是运输项目设计和交付的进步，安全地利用机器人技术以及对人工智能的承诺，从乐观主义偏见到所有事物的承诺在计划到基于图像的进度跟踪时取消。

与会者分享了有关建筑，设计和能源技术的策略，例如数字双胞胎，使用物联网的传感器以及AI的多种用途 - 用于重复出现的项目执行挑战。在讨论的AI创新中，包括在Bechtel的公用事业级太阳能生成项目上进行的机器人技术和Nextera Robotics使用的自动漫游者的自动挖掘机操作，以捕获Gilbane Building Co.的过程中工作图像。新利18备用网址

Nextera Robotics的合伙人Lana Graf，国际金融公司的AI和Deep技术投资者说，AI和制造过程刚刚在施工中生产自动机器人技术，Solutions Nextera帮助Gilbane在其项目上使用了该项目，该项目专注于消除消除消除消除的项目新利18备用网址施工生产力差距，质量更好的控制，施工速度的提高和减少废物。

AI: Best Case Scenarios

Bechtel Chief Innovation Officer Keith Churchill and Ken Burke, the firm's Global Operations Manager in equipment explained how Built Robotics was able to create fully autonomous excavators that dig trenches for major solar farm projects in Texas and Louisiana. Built Robotics Vice President Gaurav Kikani stressed that repetitive tasks where safety can be controlled—such as trench digging—are the best use-case scenarios for autonomous robotics such as on the firm's excavators.

Churchill said the competitive labor market allows skilled operators to manage the work of the autonomous excavators rather than spend hours at a time digging trenches. Kikani said the close work Built Robotics did with Burke's team in Bechtel's Houston area equipment lab allowed the firms to optimize the autonomous excavators. One safety measure was using a geo-fence with all personnel instructed to stay out of it for the autonomous excavators to dig their trenches in.

业务经理Eric Cushman Gilbane的康涅狄格州ecticut business unit, agreed that repetitive tasks that do not take advantage of skilled workers' talent and experience are the best use cases for robotics in construction.

最后使用人工智能的探索by Wan Li Zhu, co-founder and managing director at Suffolk Technologies, and Dev Amratia, CEO of nPlan—one that took it entirely out of the field.

萨福克（Suffolk）正在试用NPLAN的计划分析工具，它说可以揭示项目调度人员的“乐观偏见”会造成风险，因为分配时间或资源不足以完成安排活动的完成。NPLAN的建议基于AI的建议，将研究的新时间表与其500,000个建筑项目的数据库进行了比较，代表1.4万亿美元的工作及其逐项活动成果。新利18备用网址

"Our algorithms ingest historical scheduled data. They see the monthly pay, the baseline schedule, and the every-month progress update, all the way until the as-built file, Amratia said. "We see what the original assumptions were, and what actually happened—which is reality."

Biases can come from data sets themselves, Amratia said. Artificial intelligence developed by companies such as nPlan andDoxelcan identify hiccups in schedules before they happen in the field.

Energy When You Need It

One developing technology arena explored by the more than 500 architects, engineers, construction professionals and vendors attending tackled the ongoing problem of renewable energy storage with a gravity-based approach.

John Jung, president of Energy Vault Solutions, explained that the aging infrastructure of energy grids, in the U.S. and abroad, needs better long-duration energy storage. Whether it's AC or DC power, the rolling blackouts, unexpected grid destabilization and costly high-use days are forcing utilities and grid managers to add new and innovative storage options. Jung said this will affect how contractors will need to work to deliver next-generation facilities.

Energy Vault's solution uses the inverters and turbine-turning principles of pumped hydroelectric power but without the water—using gravity instead. Excess potential energy comes from the basic equation of potential energy equals gravity times mass times height. By hoisting and holding at height 30-ton mobile masses, Energy Vault's demonstration project in Italy has already shown they can store excess generated energy as potential energy. The company is now moving toward building functional energy storage sites connected to real power grids.

"The mission is to accelerate decarbonization of our planet by introducing the most sustainable and economical energy storage techniques," explained Jung. Energy Vault wants to, eventually, sell its products to utilities, independent power producers and large industrial energy users to reduce their overall cost of energy.
