The site is located at 88-92 Madison Ave. in Hempstead, Nassau County, New York. The site is developed with a one-story warehouse with no basement, associated paved parking lot, driveways and utilities. The project site is bounded by Madison Ave. to the north, commercial buildings to the east and west, and Sewell St. to the south. The project involved the existing building rehabilitation for the Lakeville Ambulette Transportation building.
The existing building showed signs of distress and settlement that produced step cracks on the building exterior walls and interior slab with more concentration around the building columns. JZN provided a forensic geotechnical investigation to assess the subsurface soils conditions, determine the possible causes of the building distress and provide recommendations for the structure’s remediation. The investigation included the drilling of soil exploration borings inside and outside the existing building and collection of floor slab concrete samples for laboratory testing.
The investigation revealed the settlement was caused by existing uncontrolled fill materials underneath the building footprint area. JZN Engineering recommendations included the stabilization of the uncontrolled fill material by soil mixing with grout to dandify the existing fill and reinforcement of the existing building wall.

The project included the renovation of an existing 44,000 square feet retail building into a new space to be used for the Northwell Health Cancer Center located at 440 East Main Street, in Bay Shore, Suffolk County, New York. Part of the renovated spaces would be utilized to store program elements and major medical equipment that would induce larger loads than the existing building ever experienced.
The existing facility was founded on shallow spread footings and slab-on-grade. A paved parking area borders the site to the north and services the existing bank and general retail single-story buildings. Residential buildings border the site to the east, south, and west. Montauk Highway runs north of the site and South Saxon Avenue runs east of the site.
JZN Engineering provided geotechnical investigation and engineering services to assess the subsurface soils conditions and provided geotechnical criteria for use by the design engineers in preparing the foundation design, and provide recommendations for earthwork and construction. The field investigation included the performance of soil exploration borings and monitoring wells. JZN recommended that lightly loaded sections of the building could be supported on shallow foundations, and the heavy loaded sections of the building would require underpinning by means of installing helical piles to support the existing building foundations or support new building foundations.
