    A6 到曼彻斯特的辅路

    英国英格兰曼彻斯特

项目概要

项目

Grontmij 需要为英格兰曼彻斯特的一条 10 公里长的双幅道路提供详细的设计、施工和缺陷责任维护。该项目耗资 1 亿英镑,涉及该道路与 A6 交叉口的几何布局和信号控制,4 处需要与 Network Rail 建立主连接的铁路结构、桥梁工程、公用设施改道,并且需要克服曼彻斯特机场航线带来的限制。Grontmij 的办公室分布在 6 个地点,有超过 200 位员工联合提供 15 种专业支持,因而需要有一个协作式的集成建模环境来满足三个不同市政客户的需求。

解决方案

Grontmij 借助 Bentley 技术实施了联合 BIM 流程,使所有利益相关方均在一个可靠的协作环境中开展工作,提高了整个项目期间的决策效率。Grontmij 创建了 160 多个模型,使承包商在项目早期就能访问这些模型并据此确定虚拟施工顺序。他们对铁路结构的接触网开展点云测量,并以虚拟方式针对临界净空限制分析三维模型,随后将结果通过 ProjectWise 提供给分散在各处的交付团队。Bentley 应用程序的信息移动化和集成建模功能对该项目的成功发挥了至关重要的作用。

成果

虚拟联合模型的采用帮助打破了专业之间的壁垒,图解说明改进了评估过程,从而推动了他们快速有效地做出决策。Grontmij 结合使用 Bentley Navigator、Bentley MXROAD、i-model Composition Server(原 i-model Composer)、OpenRoads 和 ProjectWise 等多种软件,在一个集成建模环境中高效地工作,最终实现了更精确、更安全、更高效、更具成本效益的设计。这些设计在进入现场实施之前已在虚拟环境中完成构建并针对各种假设条件和交互情况进行了测试。该联合 BIM 战略使所有项目利益相关方都能够以真正协作的方式开展工作。

软件

使用 ProjectWise 作为通用数据环境简化了对当前信息的访问,节省了跟踪修订所需的大量时间,同时最大限度地降低了风险。Grontmij 采用 MXRoad 和 OpenRoads 交付基于模板的设计,使各方都能够以虚拟方式对整个铺装层和施工深度进行评估。通过将 i-model 技术与 Bentley Navigator 相集,可在设计阶段中分析 200 多个冲突检测规则。Bentley Navigator 联合模型在确保虚拟跨专业协商会议取得高效的设计评估方面发挥了关键作用。
Outcome/Facts
  • The innovative use of Bentley products in a digital design-based BIM methodology helped minimize risk and facilitated information mobility for the optimal collaboration needed to deliver this GBP 100 million project.
  • Using ProjectWise as a common data environment allowed Grontmij to develop downstream workflows that supported their use of Bentley modeling tools, enabling the team to produce more coordinated, accurate, cost-effective, and buildable designs.
  • Grontmij implemented a federated BIM strategy to facilitate collaboration with three different clients, and among a multi-disciplined team of 200 people dispersed across six locations, to deliver a 10-kilometer dual carriageway in Manchester, England.
Quote:
  • “Grontmij as Design Partner and BIM manager has worked in a truly collaborative manner with both our client and the local councils, across 6 locations, creating in excess of 160 models to date. Working in a common data environment, whilst encompassing the federation and clash detection process has been a significant step change for us as a designer, but the value gained by such an approach is also quickly apparent including the improved integration of the individual disciplines. Without the innovative use of Bentley products (MicroStation, MX, Open Roads, MX Drain, Navigator, i-model Composition Server (formerly i-Model Composer), and ProjectWise in a digital design-based BIM environment, delivering this project would have been infinitely more difficult and certainly much riskier. ”
