Located on a 1.4-acre site, the 11-story, 255,600-sq-ft building contains 192 units dedicated to senior living. It also has a three-story parking garage, an indoor pool, theater, chapel, fitness center and salon. Pre-installation meetings with subcontractors ensured compliance with all design details, a critical step given the predominance of high-end finishes and the need to prevent costly, time-consuming rework.
The small site presented many logistical and operations challenges. Unstable soils and a susceptibility to sinkholes required six weeks of preconstruction site mitigation with compaction grouting. Instead of a tower crane, the team used a 300-ton mobile crane and hydraulic mobile scaffold. Operations were meticulously sequenced to support just-in-time material deliveries. An agreement with an adjacent property owner provided a much-needed half-acre lot for laydown space and construction trailers.
Materials coming from Canada were halted temporarily due to border closings, and lead times for prehung doors and frames grew seemingly by the day. Scrambling to keep the project on track, the team sought other suppliers while repeatedly revising schedules and resequencing work. Weather also contributed to a month-long delay in completing the precast garage, affecting the start of structural work for the facility’s memory units. With so many subcontractors on site during the pandemic, synchronized activities also maintained safety, social distancing and the schedule, the team says.
