Project Goal

Jacob Construction & Design, Inc. was required to replace all sanitary waste lines within hangars 2, 3, and 4 at Naval Air Station Fallon in NV. Description Jacob Construction & Design, Inc. responsible for replacing out all sanitary waste lines within Buildings 42, 462, and 431 from source to 2nd floor. Demolition efforts involved removing existing cast iron plumbing lines and replacing them with ABS equivalent. This project was one for one replacement of all piping and fittings of the sanitary waste water system in each of the three hangars. For this project, access into the interior wall space was the biggest challenge. A couple of the hangars had rooms with various levels of security restrictions that required escorts. In many of the restrooms and locker rooms, walls had to be demoed out and fixtures/tiles/mirrors/urinals removed to access the pipes for replacement. Therefore, build back of these walls required some effort as restoration involved installation of new wash counters, tiles, and mirrors. As the 3 buildings were fully occupied with TOPGUN and CAG exercises underway, coordination of phased work areas ensured JCD work efforts did not impact normal tenant operations. Outage work required planning as one outage temporarily decommissioned the water service in multiple hangers. All demoed sewer lines had to be capped and carried down stairs and out the building as staging zones were limited due to road access restrictions. As the sanitary system was gravity fed, testing for leaks was conducted via release of peppermint oil. Overall, JCD successfully completed the project early with all fixtures/walls restored to its previous condition.
