When the Third Set of Locks of the Panama Canal Expansion is completed, it will double the capacity of the Panama Canal
through integrated components including two Post-Panamax lock facilities, one on the Atlantic and one on the Pacific side. The project will double the canal's capacity, providing significant benefits to local, regional and global economies.
portion of the estimated $5.25 billion project. MWH lock design specialists are delivering a system that will enable high throughput, efficient operation and maintenance, with minimal water consumption, all within stringent technical requirements and specifications established by the Panama Canal Authority (ACP). Examples of these design solutions include:
loads, enabling more efficient structures that achieve the performance goals for strength and durability. Seismic design: Using state-of-the-art seismic analysis techniques, MWH is developing lock wall configurations that meet stringent seismic criteria at minimum cost. Water consumption: Water saving basins – the largest in the world – are designed to reuse 60 percent of the fresh water consumed for lockages, with an optimized filling and emptying system that meets aggressive performance criteria for system efficiency and throughput. Integrated operations and controls: Through optimum design of operational features and control systems, lock operations will be seamless and efficient. Design of the lock operating gates for rapid opening and closing, coupled with an efficient filling and emptying system based on innovative hydraulic design and state-of-practice control technologies, ensures that system safety, efficiency and throughput are maximized.
request of ACP. The BIM process, together with Autodesk BIM software, has supported the design team's efforts to advance the state-of-practice on many components on the project. The BIM process allows for improved quality of design, increases productivity by efficiently managing design changes and helps facilitate communication with clients and builders through visualizations.
components and systems, overlay of electrical, mechanical, architectural and civil/structural elements to identify and eliminate conflicts (clash detection), and production of civil/structural backgrounds for use by electrical and mechanical designers to lay out their systems. Virtual clash detection eliminates field construction changes that can be costly and challenging to project schedules. Two-dimensional construction drawings are extracted from the BIM model, which is developed with all of these factors in mind, for use by the contractor.
intelligent 3D models has allowed this diverse team of engineers to collaborate efficiently, helping them to resolve design conflicts prior to construction, allowing for better coordination and ultimately saving time and money.
client evaluate multiple design options. Autodesk Revit Architecture, Autodesk Revit Structure and Autodesk Revit MEP: Used for detailed design of the Canal's new lock structures, operations buildings, and multitude supporting facilities AutoCAD Civil 3D: Used to help create more efficient and accurate site designs. Autodesk Navisworks Manage: Used for improved multidiscipline coordination and collaboration, helping resolve design conflicts prior to construction, increasing the quality of the project, and helping to prevent costly field changes.
AutoCAD Electrical: Used by the electrical subcontractor to MWH Global for the electrical schematics and panel layouts. equipment identification tags for inclusion in a master maintenance manual incorporating project models and data.
As one of the first applications of BIM to a project of this magnitude, there have been some "lessons learned" along the way. The design-build team ultimately guides the pace of the project and, at times, a more conventional approach is needed to adhere to schedule and timely delivery of work products. As the application of BIM progresses in project delivery, it is important for project teams to be flexible. MWH has found that BIM structural models must be customized to be useful for large-scale, unique structures such as dams and navigation locks. While the software tool is a key component of BIM, embracing the integrated design process that it enables will allow project teams to achieve the full benefits available.
advancing many design elements in parallel, with BIM providing the mechanism to integrate design changes as necessary to keep the project on track. Having made the investment to adapt the BIM workflow and application of the software on this world- class project, MWH now has a template for applying BIM to similarly complex projects worldwide. 摘自http://www.gostructural.com/magazine-article-gostructural.com-10-2012-bim_canal-9027.html)>http://www.gostructural.com/magazine-article-gostructural.com-10-2012-bim_canal-9027.html |
