Proj Overview

Project Overview

Mariano’s grocery at 16th and Clark in Chicago is a complete three story precast structure with the first level retail and two upper levels of parking.

Challenges included preventing water intrusion into the store from the garage and determining the garage ramping in the tight space. The garage was designed with jump ramps to accommodate the rapid inclines in the compact building footprint. To separate retail from parking, the floor structure above the retail area includes untopped double tees, a rubber membrane, insulation, and then a traffic coating.

Precast Solution

Exterior precast panels are load bearing with cast in thin brick. The exterior panels utilize white cement, tint additive, acid etch and two colors of utility-size thin brick. An intricate pattern of two brick colors dominates the exterior and gives the effect of depth to the panels.  

The interior consists of precast columns, beams, stair/elevator shafts, double tees, precast stairs, and solid slabs.
