About this Project

LEAN Design

This project utilized Lean planning practices in design, construction, and target value estimating.

This substation and automatic transfer switch replacement project replaced the emergency power branch switchgear and electrical infrastructure for the hospital, including the design of a new 8,000 SF penthouse at the existing roof level of the hospital to house the new electrical gear. The project presented many logistical challenges due to the existing conditions and the quantity of conduits that were required to feed the existing hospital programs.

The team raised the new floor level of the penthouse to allow for the construction of a new structural slab designed for the new equipment load’s electrical gear, and provide a new interstitial space to route the conduits from the existing risers to the new electrical gear. Once construction of the penthouse was completed, a series of electrical shutdowns were scheduled with the hospital clinical programs to transfer the existing emergency power circuits to the new electrical gear, coordinated over the course of several months.
