GEOTECHNICAL ENGINEERING PROJECTS


Rubenstein Ecosystems Laboratory

> Burlington Waterfront Housing PDF
Burlington, Vermont

A 5-story apartment building on a site containing unstable slopes which had resulted in a 15-inch settlement of neighboring Depot Street. In addition to determining soil-bearing capacity, the 2-phase geotechnical investigation involved slope stability analyses, concept development and design review.


> Bay Road Stabilization PDF
Colchester, Vermont

The road edge and guardrail along a 110-foot section of Bay Road began to settle (>3”/year) shortly after re-construction in the early 1990’s. The geotechnical investigation involved soil borings and slope stability analyses. The design repair scheme utilized 25-foot deep anchored sheetpiling.


Waterfront Housing Development

> Burlington Waterfront Park Boardwalk and Promenade PDF
Burlington, Vermont

The focal point of Burlington’s Waterfront Park is a 700-foot long shoreline boardwalk and promenade north of the Burlington Boathouse. The 16’-wide boardwalk is an at-grade structure providing access to the shoreline; the promenade is a pile-supported structure extending out over the water.


Route 127 Ramp Stabilization
Burlington, Vermont

In 2001, an 80-foot section of roadway embankment failed. In addition, a new bike path was to be constructed in 2 years; this would worsen the slope during construction. The project involved analysis and design of cantilevered sheetpiling to provide temporary and permanent stabilization.


Chittenden County Interim Regional Landfill
Williston, Vermont

HDPE-lined regional landfill at the site of the existing Williston Landfill. Analyses included stability analysis of the liner system, as well as the existing earth slopes and projected fill slopes. Fill slope analyses included pore pressure modeling of medium stiff clays under a 100-foot high embankment and modelling the stability of trash under the weight of new soil berm.
