Concrete slab pour 1B was supposed to be routine, occurring early in the construction of a parking garage in the Midwest. However, low compressive strength issues led to lengthy and costly project delays, as well as some interesting theories about the causes.
The theme of transportation was dominant when architecture firm Leo A. Daly designed a five-building distribution center for Dollar General in Bessemer, Alabama. Rather than opting for a conventional finish on the warehouse’s precast exterior walls, the Omaha-based design firm sought a visual way to bring the theme to life.
While heating exterior penetrations wastes energy and increases carbon emissions and operating costs, chilling interior structures reduces comfort and allows condensation and mold to form on adjacent surfaces. Therefore, one must look for an alternative solution.
The American Concrete Institute has introduced a new decorative concrete flatwork certification to its programs, allowing individuals to earn two designations: decorative concrete flatwork finisher and decorative concrete flatwork associate.
When it comes to parking garages, durability is key, as they are often located in busy metro areas where closure, repair, or reconstruction can be disruptive. Time, labor, and material costs for renovation are also prohibitive. These structures are generally made from reinforced cast-in-place or precast concrete, making corrosion one of the most common challenges to durability.
