Flatiron Constructors placing concrete for drilled shafts at Abutment 2. A laser level was used during concrete placement to determine top-of-shaft elevation.
Vivid Engineering performing quality control testing on the drilled shaft structural concrete. Air content, slump, temperature, and unit weight testing was performed on each truckload of concrete, as required.
Flatiron Constructors placing concrete for drilled shafts at Abutment 2. A concrete pump was used to place concrete in the bottom of each shaft.
Snow’s Specialty Drilling performing drilling of 24-inch diameter shafts at Abutment 1.
Flatiron Constructors installing an elliptical reinforced concrete pipe (RCP). This culvert will gather runoff generated along Moraine Ave, the new roundabout, and portions of Riverside Dr.
