Allana Buick & Bers, Inc. was retained by Equity Properties to provide services to the replumbing project of the domestic supply and waste water systems at Nu’uanu Tower located in Honolulu, Hawaii.

Nu’uanu Towers is a 12-story, reinforced concrete structure located on Nu’uanu Avenue. The condominium style tower has 10 floors, each of which, contain 4 dwelling units and is situated over two floors of covered parking.

Phase one of the project included a pilot project that defined the scope and budget parameters. Allana Buick & Bers’ staff of licenced professionals provided leak investigation, conducted observations and assessments for all the piping: waste, supply and venting, with destructive testing that included the removal of cross sections of waste piping for analysis.

Allana Buick & Bers visited the ground floor utility room and an area in the ground floor of the parking garage where the cast iron waste piping had been replaced with ABS piping. A portion of the piping travelling below the pavement was also replaced with ABS. It was decided that this portion of the work should be reviewed but not subject to destructive testing.

The second phase was the construction phase. Allana Buick & Bers prepared repair documents as the mechanical engineer of record suitable for permitting and bidding purposes and managed the competitive bidding process. Allana Buick & Bers provided construction administration and construction monitoring services for the mechanical systems. The construction phase included managing the intrusive nature of the project and complex scheduling with the contractor and occupants who were allowed to stay in their units during the piping replacement repairs.
