Solution:

Several solutions were considered for support of the buildings. This included driven piles and surcharging fill load. The latter was deemed implausible due to the unpredictable decomposition of organic/peat material. Menard, ultimately, provided an economical and time-saving solution with CMCs.

Menard began design assistance in 2018, however, construction and installation of CMCs did not begin until 2021. Installation was performed in multiple phases across four years. First, was the medical center (232 CMCs); Second, the apartment complex (251); and Third, the mixed-use buildings (916). The CMCs were installed to an average depth of 82 ft. Menard designed each building for footing and slab support with column loads ranging from 48 to 732 kips. Strip footings were designed for 1 kip/ft up to 3 kip/ft; slab support for 100 to 150 psf. The design provided for 1 in of post-construction settlement, with a ½-in of differential settlement, meeting the performance criteria of the new structures.

For a three-phase project spanning multiple years, Menard successfully installed nearly 1,400 CMCs to support three new structures at the Cayuga Park Complex in Ithaca.
