Grunley converted an existing 30,000 square foot parking garage into a suite of offices and a daycare center. The scope of work included demolition of the existing garage spaces, structural strengthening, extensive negative side waterproofing of the below-grade walls, two new glass entrance pavilions and installation of high-end tenant improvements. In addition, we provided glass partitions, a decorative glass tile feature wall, patterned terrazzo flooring, custom stainless steel decorative ceiling assemblies and display cases, integrated building automation systems, as well as complete mechanical, electrical, fire alarm, communications and security systems replacement. The museum remained open and fully operational during the construction process. Many tasks were completed at night in order to avoid conflicting with the visitors’ safety and quality of museum experience.
