When bidding on large-scale modular projects, and specifically the scope of on-site assembly, the likelihood of success is governed by: (i) the capacity to respond rapidly to changes requested by owners; and (ii) the ability to clearly represent all the details of crane operations, including: (a) crane selection; (b) location of pick points; (c) crane path planning; and (d) a digital lift animation emphasizing proper rigging configuration, crane swing direction, and potential lift obstructions. A bidding proposal that addresses these operational details signals to the owner that the proponent's engineering team not only has thoroughly investigated and understood every aspect of the project, but is also able to integrate these elements within an animation platform to help the stakeholders (including the owner) refine their understanding of alternative assembly scenarios and thus conduct a well-informed tendering process. In this context, the key deliverable of the proposed research will be a decision-support system that can generate level-4 crane schedules for a complete project (4D), based on 3D simulation of each lift in the project, which can, in turn, form the basis of cost estimation (5D) for the purpose of bidding, comparison, and execution. The generating of various scenarios based on this 4D and 5D information will culminate in an optimization approach in the form of value engineering selection criteria (6D), based upon which the partner organization can select the best available solution that satisfies the project requirements (i.e., a scope triangle). The potential benefits of this research include increased competitiveness of Canadian crane service enterprises; reductions in the carbon footprint of construction due to increased efficiency of crane operations; improved equipment selection (preventing overdesign and thereby reducing CO2 emissions with respect to ground preparation and transportation of equipment such as crane components, rigging, and crane mats); and improved safety (through streamlined operations and improved communication between lift planners and rigging crew/operator).

在对大规模模块化项目，特别是现场组装的范围进行投标时，成功的可能性取决于：（一）对业主要求的变化作出迅速反应的能力;（二）清楚地说明起重机作业的所有细节的能力，包括：（a）起重机的选择;（B）挑选点的位置;（c）起重机路径规划;以及（d）数字提升动画，其强调适当的索具配置、起重机摆动方向和潜在的提升障碍物。一份解决这些操作细节的投标书向业主发出信号，表明投标人的工程团队不仅已经彻底调查和了解了项目的各个方面，而且还能够将这些元素整合到动画平台中，以帮助利益相关者（包括业主）完善他们对替代装配场景的理解，从而进行充分知情的投标过程。在这种情况下，所提出的研究的关键交付将是一个决策支持系统，可以生成一个完整的项目（4D）的4级起重机时间表，基于项目中每个升降机的3D模拟，这反过来又可以形成成本估算（5D）的基础，用于投标，比较和执行。基于该4D和5D信息生成的各种场景将以价值工程选择标准（6D）的形式的优化方法达到高潮，基于该标准，合作伙伴组织可以选择满足项目要求的最佳可用解决方案（即，范围三角形）。这项研究的潜在好处包括提高加拿大起重机服务企业的竞争力;由于提高了起重机作业效率，减少了建筑的碳足迹;改进了设备选择（防止过度设计，从而减少地面准备和设备运输（如起重机部件、索具和起重机垫）方面的CO2排放）;提高安全性（通过简化操作和改善提升计划人员与索具组/操作员之间的沟通）。
