Block 162 Case Study
Block 162 is a 30-story, column free, office building in the heart of Denver with panoramic Front Range views. The winner of the 2021 ConRock Colorado Magazine photo cover contest, this project showcases the innovative design possibilities of concrete construction. CRMCA member, Martin Marietta was the supplier for this project.
CRMCA and NRMCA worked together to create a case study to promote the LEED Gold certified building and its energy efficient components that work perfectly for a traditional office environment while also offering a creative office space.
The Block 162 office building secured a LEED Gold: Core and Shell rating due to the following design elements:
- Structural Floor System: Cast-in-place concrete supported by composite steel deck
- Columns: Rolled steel wide flange columns, girders and floor beams
- Lateral Load Resisting System: Cast-in-place concrete core shear walls
- Live Load: 50 PSF + 15 PSF for partition for office area and 100 PSF for core area
Removing interior columns allowed for a spacious floor plan but required upgrading the concrete core of the building. By choosing a self-climbing concrete core, developers were able to achieve consistent layout of the embeds, rebar and other core penetrations that could be used over and over, instead of having to layout and rebuild the core for each floor.
Choosing concrete for this project allowed the building to be designed and constructed with strength and durability at the forefront.
