City wanted 120 lineal feet. under the Viaduct filled with concrete. Area was 14′ deep and approximately 12′ tall. This situation created a one sided pour with 700 yards of concrete.

Goedecke design team utilized our Alisply forming system for the one sided pour. Anchorage points were a back wall and concrete beam over head. 1/2 coil rod sufficed as the ties. Mega drilled 7″ diameter holes in the sidewalk above to discharge the concrete to fill the cavity below

Pour pressures were critical. Mega took approximately 7 hours to pour. Forms did not budge and it turned out perfect.
