125 Lake Street
The North Tower parking garage at Stepping Stones Apartments had reached a critical state of deterioration. Aging reinforced concrete slabs, corroded steel beam connections, and compromised structural integrity demanded a comprehensive intervention — not a patch job, but a full structural rebuild of the garage and exterior ramp. DeRosa Builders engaged L&M for the complete structural restoration scope: new W12x50 steel columns with epoxy anchor systems, full concrete deck demolition and replacement with a new 6-inch reinforced slab on composite metal deck, waterproofing membrane systems, and a new asphalt driving surface — every phase coordinated with temporary shoring to maintain structural stability during active demolition.
