38 Utility Contractor | May/June 2018 C onstruction, construction, con- struction. Road construction as far as the eye can see. This is what residents in Columbus, Ohio, think when they travel practically any- where. And due to the multi-year Inter- states 70/71 Columbus Crossroads proj- ect, many freeways downtown will be under construction into the next decade. With a civil project as large as the 70/71, a lot of the construction is not just road paving and bridge reconstruc- tion; it is the installation or rehabilita- tion of underground utilities such as the miles of pipes for gas, water and sewers. Though perhaps a little less high-profile, these out-of-sight infra- structure projects are just as important. Taking on one of these behind-the- scenes — though no less extraordi- nary — infrastructure projects was SHELLY & SANDS Inc. (SSI), based in Zanesville, Ohio.

This was not an easy excavation proj- ect. It was in fact, four different exca- vation projects; each a different depth; some with different soil conditions; some with existing crossing utilities to navigate; and each having different sized pipes, structures, and/or manholes to install within. Complicating matters fur- ther was that the Best Management Prac- tices (BMP) sewer project needed to be installed over a length of one block that was bordered narrowly between a west- ern section of the I-70/71 corridor and an apartment building. No Easy Solution All four excavation points were deeper than 5 ft and required a trench protection system per OSHA regula- tions. "The first thing we considered were trench boxes; possibly using the equipment that we had in our fleet or we could easily rent," said Brian Snode, SHELLY & SANDS' Project Superin- tendent. "But we realized with the soil conditions and the existing utilities that were in the ground, plus the surround- BUILDING THE BACKBONE Zanesville, Ohio's SHELLY & SANDS Inc. recently completed a Best Management Practices infrastructure project for the multi-year Columbus (Ohio) Crossroads I-70/71.
