Solution: Hollowcore and precast and prestressed columns and beams provided a reliable foundation for a 150-unit apartment complex.
Multifamily Builders Rely on Hollowcore for Structural Foundation and Underground Parking
Ramsey County, Minnesota, home of the state capital, has been experiencing a surge in demand for housing. Oberon, a 150-unit market rate apartment building, was developed to help meet that demand. The five-story building offers a variety of unit types from alcove to three-bedroom, and includes a fitness center, pool, rooftop deck, and clubroom.
Project leaders specified precast and prestressed concrete structural elements to build the foundation and one level of underground parking. The use of hollowcore plank and precast columns and beams provides many benefits during construction and after occupancy. Hollowcore is manufactured in our PCI-certified production facilities and delivered on site ready to install. This can accelerate project timelines because production can happen while the site is being prepared, and installation can be completed in a few weeks. Once installed, hollowcore serves as an instant, stable workdeck for other construction trades.
The inherent strength of hollowcore allows it to achieve wider spans with fewer support columns, maximizing the usable interior space. The high mass of hollowcore also provides acoustical dampening and high fire ratings.
Project Highlights:
Erection of the building’s foundation was streamlined by the use of hollowcore and precast columns and beams. The whole foundation was completed in less than two weeks, helping the $42 million project stay on track for its scheduled opening date.
