Puertos Logísticos de México Multipurpose Wharf

SGH designed the structure for the 550 m long and 38 m wide marginal wharf under an engineering, procurement, and construction contract following early contractor involvement delivery protocols. The wharf’s deck structure comprises a system of precast concrete plugs, subcaps, crane beams, transverse beams, and pretensioned deck panels supported on piles. Key considerations include:

• Selecting a structural system conducive to top-down construction, which allowed for an accelerated construction schedule
• Designing for seismic loads using nonlinear pushover analysis techniques
• Detailing of pile-beam joints using deck capacity protection principles per ASCE 61 and AASHTO
• Supporting heavy cranes: 300 m will be used jointly by ship-to-shore cranes and mobile harbor cranes (MHCs) and the remaining 250 meters by MHCs
• Driving open-ended 0.9 and 1 m dia. steel pipe piles up to 45 m into silty sands
