Shear Walls & Columns

Rebar is standing tall and concrete is being poured. After digging in the dirt for weeks, we are finally coming out of the ground with Shear Walls and Columns. The soil in this area has a large amount of rocks. The ground is affectionately known as “potato” dirt. Unfortunately these little potatoes can be as large as 4’ in dia., which makes shoring piles interesting to say the least. Not to mention the spread footings end up being over excavated as the soil will not maintain a true edge. Although the foot print of the site is around 40,000 sf there is only one ramp access and with the large size of the footings and numerous columns, real estate in the hole is at a premium.

Project History

The project was made possible from a donation by The Marie-Josée and Henry R. Kravis Foundation. In recognition of this gift, the College is designating this new signature building as "The Kravis Center."

We have a live webcam (link to your right) that captures the jobsite. Look how far we've come!

W.R. Grace SCS Waterproof System

CMC elected to use a new waterproofing system for blind side waterproofing at the shot-crete retaining walls. Installed by Best Contracting, the waterproofing is injected through ports after shot-crete is placed. The liquid hardens and bonds to the concrete.
