Nathan's career with KPFF began in 2001 with a focus on management, planning, design, and multi-discipline coordination of large waterfront site development construction projects in Port environments. Prior to joining KPFF, Nathan spent 6 years focusing on mechanical engineering/machinery design for movable bridges and other heavy movable structures. Nathan’s dual qualifications as a registered civil and mechanical engineer have proven to be useful for planning, design and multi-discipline coordination of the complex infrastructure systems that are required for waterfront industrial sites. Nathan specializes in complex multi-discipline project management and manages projects ranging from marine wharf upgrades, terminal redevelopments, utility infrastructure upgrades, vessel shore power, dredging, and marine habitat mitigation projects.
