Overview

The basement of the State House Annex building in Trenton, New Jersey, experienced a water infiltration problem. Whitman was selected to provide civil engineering design to develop a method to waterproof the exterior of the existing foundation walls. There was an intricate structural component as part of the design in order to save the existing masonry stairs and terrace in two locations. Groundwater testing wells were installed and monitored for a full year to determine seasonal fluctuations of the existing water table.

The groundwater analysis warranted a redesign of the initial water infiltration solution, saving the state over $200,000 in construction costs.
