The Infinity is a luxury residential complex with 4 post-tensioned concrete structures ranging in height from 8 to 41 stories. The 1-million-square-foot development includes 654 condominium units, a fitness center, swimming pool, courtyard, lounge, retail space and a 5-level subterranean parking garage.
During the excavation of 190,000 cubic yards of soil, workers uncovered a 19th century whaling ship. Webcor overcame the delays associated with the ship’s removal and an unusually wet winter by achieving a 4-day, floor-to-floor structural concrete pouring cycle. Using an innovative combination of concrete forming systems, Webcor poured the 36-story tower, 5-levels of parking and 7,000 cubic yard mat slab in 356 days and within 1 week of the original schedule.
Using lessons learned in phase I of the project, Webcor streamlined many aspects of the construction for the 41-story tower of phase II. Innovations in the life safety testing process dramatically reduced the construction schedule and allowed the project to be delivered 3 months ahead of schedule. Despite a noise-related work-day restriction of 7 a.m. to 8 p.m., the team achieved a 3-day per floor structural concrete cycle—beating the speed of the Phase I tower by an entire day.
