SFO’s US$2.6bn Terminal 3 Project seeks to renovate and expand the existing terminal while maintaining live airline operations of 37 gates. The project constructed two temporary elevated passenger corridors to route passengers around the construction site to optimize passenger experience and safety, construction efficiencies and phasing reductions, cost and schedule savings and sustainability. 11 prefabricated modules, each with complex finishes and MEPF/SS systems, were transported across the airfield at night and set into place with a ¾ tolerance. Extensive preplanning and coordination were critical to the success and enabled project delivery one year earlier.

• How to operationally maintain a high level of passenger experience during phased construction of a megaproject and existing facility
• The benefits of faster installation through off-site prefabrication, leading to quicker project completion
• The positive impacts on gate operations, including longer availability of active gates and earlier start of terminal construction
• The enhanced safety measures resulting from reduced on-site construction activity, lowering safety risks to the active terminal
• The cost savings achieved through prefabrication, which allows for landside construction and easier working access
