Under contract from the Nebraska Department of Roads (NDOR), Hawkins Construction Company was awarded a contract to construct a noisewall along I-680 near Blondo Street west of downtown Omaha.  A cooperative, innovative design of the foundations and precast posts offered unique benefits to Hawkins in terms of material costs and an improved construction schedule.

An alternative design had been previously submitted and accepted by NDOR facilitated a quick start for RECo and Hawkins to employ the design which encompassed 19,192 square feet of facing area consisting of 272 individual precast units manufactured by American Concrete Products, Inc.   The key design feature focused on the mechanical connection of the precast posts to the drilled shafts.  Two corrugated metal canisters are pre-located in the empty shaft to form the lower half of the structural connection.  Anchor bars extend from the bottom of each post and are aligned with and inside of the two embedded canisters.  The post is then temporarily supported allowing for flexibility to make adjustments in terms of roadway offset, post spacing and post alignment.  Once all the adjustments are complete, the embedded canisters are filled with high-strengh grout.
