Our client was a 50,000 SF full-building tenant coming to the end of a 10 year lease term.  It had problems with frequent roof leaks, as well as HVAC issues.  It also needed to improve its loading, add supplemental air conditioning to its IT Room, and upgrade its office space.  The tenant distributed, repaired and maintained sensitive medical testing equipment, and warehoused and distributed chemicals and reagents used in that equipment.  It had made a significant investment in fitting out the building for its purposes, as it converted this former warehouse building to a fully air-conditioned flex/office building.
