RW has been actively assisting in the reconstruction of interstate I-29 in Council Bluffs, Iowa for over 9 years. For the I-29/US-275 Interchange project, our teams provided construction staking of over 27,000 rigid inclusions and 21,000 wick drains to aid in the removal of storm water.  We provided construction surveying for two steel girder bridges and two concrete bridges, each over 1,000 feet in length.  Over 100 drilled shafts were staked for the bridge supports.  We staked over 3,000 feet of Mechanically Stabilized Earth (MSE) walls.  We have delivered monitoring information on 25 settlement plates for a period of 42 weeks, as well as the daily monitoring of all the adjacent bridges.
