Over a two-year span, we provided engineering design and construction management for eight separate sites, located from New York to Seattle. The project included upgrading uninterruptible power supply (UPS) systems by removing the existing units and installing new larger ones. One of the challenges of this project was to replace the UPS systems without affecting power operation to the facilities.
To meet the project objective, we came up with a unique push-pull design approach that allowed us to push the existing unit out and pull the new unit in during an 8-hour maintenance window.
Construction management and project planning required developing a detailed method of procedures. In addition, as the construction managers, we worked side-by-side with contractors to ensure all preliminary work was completed prior to starting the replacement.
Replacement of the UPS equipment was scheduled well in advance, placing the facility on generator power. Once on generator power, we synchronized a wrap-around electrical bypass with the UPS that was being replaced and brought the new UPS on-line.
The critical nature of the project required precise timing and detailed planning. As the construction manager, we were on-site for all the construction work providing engineering support and construction supervision.
