Critical Standby Power Generation Facility
Williams Notaro was retained to lead the project team for this fully redundant diesel engine standby power generation facility for a critical data center in Vienna, Va. As the prime consultant, we managed and coordinated the design effort with the required disciplines. The project team included architects, civil engineers, structural engineers, acoustical engineers, and cost estimating consultants. Our team worked closely with each consultant to develop and prepare the construction documents for the new ground-up structure and associated standby systems. We also collaborated extensively with the client to insure this standby power system met all of their requirements.
Because this new facility interfaced not only with the existing facilities infrastructure, it also was integrated into the existing structural, storm water, domestic water, and architectural systems of the facility. Because the data center the new standby power facility serves was operational 24/7, coordination with these interfaces was critical to avoid any issue that would result in service outage to the data center. Thanks to the attention to detail of our staff and the efforts of the project team, the facility was constructed on time, under budget, and commissioned without any impact on the continued operation of the data center.
