Design / Construction Completion: 2010 / 2010
Okahara and Associates, Inc. was the prime and mechanical consultant for a series Okahara and Associates, Inc. was the prime consultant on the project to design for a replacement roof mounted, air cooled chiller plant to serve Neal Blaisdell Center's Administration Building. The design team prepared a basis of design, plans, specifications and a cost estimate within a compressed schedule. Partial failure of both existing chillers shortly after contract execution required prompt completion of the bid documents. Scope of work included preparing a cooling load model, replacing existing equipment (two 70-ton chillers, chilled water pumps, air separator, chemical pot feeder, valves, and controls), rebalancing the entire air system, and preparing a construction phasing plan. Subconsultants included structural engineering, environmental and electrical engineering consultants. Okahara was responsible for $180,000 of the $240,000 construction cost. Related projects at the Outrigger Canoe Club to identify underground sewer and storm drain pipe failures, recommend alternatives to repair failing piping, and implement OCC selected repair recommendations. Mechanical scope of work involved conducting a forensic analysis of the existing underground piping system, designing for the installation of cured-in-place pipe lining in underground piping larger than 4-inches in diameter, replacing underground piping 3-inches and smaller in diameter, replacing selected plumbing fixtures, replacing four 120-gallon hot water storage tanks and installing a 750 gallon grease interceptor. Additionally, Okahara was tasked with preparing a design that would minimize disruptions to normal club activities. Okahara's professional services included project management, preparation of an engineering report, design drawings, technical specifications, construction phasing notes, cost estimates, permit applications, coordinating SMA and Archaeological efforts, and construction administration.
Estimated construction cost was $2.3 million.
