The equipment in question served four different levels of the facil- ity, and multiple access points would have to be created in the exterior of the building to get the old units out and new ones in. In addition, the proximity of many of the units inside the existing structure presented significant (if not impossible) rigging and hoisting challenges. In addition to the accessibility issues, a complete replacement would have added general construction costs.
