In 2015 Currier & Co. was contracted by AECOM to serve as their principal hydrant fuel system engineer for the City of Phoenix’s 49-phase Terminal 4 North Apron Reconstruction Project. Currier & Co. was invited to the design team after the entire new north apron was designed and the proposed elevations set. Initially, Currier was charged with the task of analyzing each existing hydrant pit’s surveyed elevation and the elevation of the existing pit internals, and then provide a recommendation as to how each existing hydrant pit should be modified to suit the proposed new apron elevations.
After gathering field data for each existing pit, and analyzing the existing elevation, proposed elevation, and the elevation of the pit internals, Currier determined that 65 of the 129 existing hydrant pits required modification. As a result of the high engineer’s construction estimate associated with this invasive work, the prime consultant requested that Currier analyze each existing pit and provide the design team an acceptable elevation range for the new apron around each existing pit, to minimize the impacts to the existing fuel system. After this exercise, Currier was able to reduce the number of pits requiring modification from 65 down to 23, which resulted in direct savings to the city of over $850,000.
