Harris County Toll Road Authority – Grand Parkway – Segment E

Stiver Engineering was retained by the contractor to provide construction engineering through an alternative design for Bents 8-11 of the Grand Parkway Segment E flyovers at the intersection of US 290 and the Grand Parkway in Harris County, Texas. We provided our client with a separate design for each bent foundation, which were designed as a single drilled shaft due to limited access adjacent to the existing lanes of US 290. We also provided the contractor with the structural designs and plans for submittal and construction of each drilled shaft.
