e-mosty March 2019 Long Span and Multiple Span Bridges - Page 16

III. RECENT PROJECT The engineering, procurement and construction (EPC) contract for the project was awarded in 2014 to the consortium of Hyundai Engineering & Construction, OAS, Aas-Jakobsen and Systra. investment on the project and it includes other items and not only this contract. When construction is complete, MOP will assume responsibility for operations and maintenance of the bridge. The consortium is also funding the project. Aas-Jakobsen and SYSTRA are responsible for the detailed design; SYSTRA is specifically responsible for producing geological, geotechnical and seismic studies, detailed designs for the foundations and designs for the central tower, the steel deck and anchoring systems. MOP instructed the project team to consider operations and maintenance efficiency and economy in the bridge design, so the Ministry anticipates that the lifecycle costs of this infrastructure asset will be optimized. Overall, MOP credits the high-quality design for this multi-span suspension bridge to the team’s using the most advanced bridge engineering applications available. The key technical challenges on this project are associated with the definition of the loads applied (impact of boats, wind and seismic activities) and the particularly complex design models. The 84-month schedule has required rapid evaluation of design alternatives, streamlined design studies, highly collaborative workflows, and accelerated reviews. Louis Berger delivers technical advisory services, including the seismic and aerodynamic analysis and evaluation during the tendering phase of the project. The Project was awarded on 17 th February 2014 for 360,134,000,000 Chilean pesos, which, at the exchange rate of the time fluctuated but they were roughly equivalent to approximately US$ 658M. At today´s exchange rate that would be US$ 546M. The US$ 740M figure is the total government Figures 5 – 7 : Renderings Courtesy of MOP Chile 1/2019
