University of Hawaii Manoa Infrastructure Master Plan

Sherwood Design Engineers was the lead designer on a comprehensive infrastructure master plan for the University of Hawaii at Manoa campus. The systems that were designed included potable and fire water, sewage conveyance and wastewater treatment, non-potable water, stormwater management including Low Impact Development and large scale harvesting for reuse, electricity and solar PV, centralized chilled water and two central utility plants, telecommunications, natural gas, drainage, and flood management. The design was informed by UH policy to achieve net zero water and net zero energy. These goals were carried through the design process and site-specific approaches were developed that embrace the unique landscape and are in keeping with Hawaiian cultural values. The master plan further helped the University resolve issues around easements, system capacities, deferred maintenance, and flood risk. Finally, a deep financial analysis was prepared to calculate the net present value of the proposed sustainable infrastructures systems and inform the University of pathways to finance and implement the master plan.
