(BIM-2854) Novel Single-side Suspension Footbridge: BIM, IPD and Cost Control Case Study

Author(s)/Presenter(s): Xuelei Pang; Chao Yu; Mengjie Chu
Time/Location: Monday, June 25 from 11:30am to 12:30pm / Regatta AB (4th Floor)


[Level: Intermediate] Wishing Star Lake Park is located beside the Shanghai Disney Resort and contains two distinctive footbridges constructed across the river. Both structures are concrete, steel and cable suspension with unique curved space beams, double decks and single-side suspension.

Two bridges contain both creative aesthetic design features and also a cleverly-created load path. The unique bridge features required different techniques in component fabrication, structural analysis and construction technology, compared with the conventional suspension bridges. There were unexpected risks in progress, performance and safety during the construction, which had an effect on the project cost control. The unique design also created new challenges for cost control, which is in contrast to  the typical suspension bridge design.

This paper reports the novel features that encompasses the architecture and structural design, cable system and construction methods. The paper outlines the successful application of Building Information Modeling (BIM) technology, post-construction loading test and the adjustment of human-induced vibration during the construction. It also discusses the cost control process by use of subdividing the novel project segments, project work flow arrangement, construction processing selecting and component selecting, and fabrication. As a case study, this paper highlights the Integrated Project Delivery (IPD), including the team organization and working methods. Based  on the IPD input, the reasonable technologies, methods and products of construction are selected, which is the key to the cost control in this novel project.

(BIM-2939) (Panel Discussion) Capital Project Delivery - Innovation Collaboration Forum

Author(s)/Presenter(s): Julie K. Owen, CCP PSP; John L. Haynes, PSP FAACE; H. Lance Stephenson, CCP FAACE; Kenneth A. McBroom, PSP; Andy Kayhanfar
Time/Location: Monday, June 25 from 4:00pm to 5:00pm / Regatta AB (4th Floor)


[Level: Basic] The innovation collaboration forum is a moderated panel discussion that looks at the challenges cities and owner agencies (innovation enablers) are having and then the companies that are there to provide solutions (innovation providers).

City and owner agency executives discuss challenges they are having and how they are enabling innovation. Key challenges involving smart city initiatives, infrastructure, enabling transit, emerging technology, and data integration are discussed.

Innovation providers will discuss how the right technology platforms can enrich the design, planning and delivery of critical assets with pragmatic approaches to BIM and digital delivery as well as the forward frontier of wearables, augmented reality, artificial intelligence and connected infrastructure.
