PROJECT

The L.R. Costanzo project team installed a structural floor slab foundation, along with a new elevator and stair towers, including a structural upgrade of exterior, foundation wall. Existing, deteriorated, vaulted sidewalks were removed and replaced.

CHALLENGES

Discovered a deteriorating concrete floor and unsuitable sub-grade material. The sub-grade material had compressed over time which caused the concrete floor to fail.
The vertical and horizontal layout of the elevator needed to be adjusted due to multiple building renovations over the years.
Extensive structural framing was required to support existing floor systems to allow elevator shaft construction.

SOLUTIONS

Over-excavated existing material and installed structural back-fill to support the new concrete basement floor and elevator foundation.
Extensive surveying was done to determine the best course of action for the layout of the elevator shaft.
Laminated beams were installed as structural members.

CONSTRUCTION DETAILS

L.R. Costanzo experts also:

Installed approximately 26,000 pounds (13 tons) of steel and 300 yards of concrete. Built four foot grade beams to support new concrete slab.
Tunneled into basement with small, excavation equipment to remove old concrete floor and excavate for grade beams and new floor.
