Penn Plaza

Penn Plaza

Scope

Penn Plaza’s eight-level underground parking garage with slab-on-steel framing services the 57-story high-rise building above it and the surrounding area, which includes Madison Square Garden. EDG was hired to conduct extensive concrete slab and steel beam repair and replacement, as well as waterproofing membrane repair and installation throughout.

Approach

To keep the garage in operation during construction, EDG carefully phased repair areas and split them up into 14 sections. The waterproofing membrane application was performed in seven phases.

Lincoln Plaza

Scope

The 33-story, 609-unit Lincoln Plaza apartment building occupies half of a city block with approximately 300,000 sq. ft. of façade. EDG was retained for emergency inspections at 30 Lincoln Plaza when previous repairs at the concrete eyebrows began to fail. The subsequent scope of work included façade inspections, preparation of repair documents, construction administration, and Local Law 11 reporting.

Approach

Emergency conditions required that EDG mobilize and assess the concerns immediately, but a complicated geometry proved challenging for inspections. One of the major obstacles of facade restoration is assessing the entire facade with only limited access. As a result, EDG does much of our work from the ground, using high-powered, image-stabilizing binoculars and telescope equipment. This technique provides accuracy, eliminating the need to perform scaffold drops on all facades prior to construction. EDG’s “hands-on” inspections are performed later to get a better idea of deterioration. During construction, EDG had up-close access to the entire facade area.

Impact

The ability to mobilize a full team quickly allowed EDG to stabilize the concerns with minimal disruption to tenants. EDG phased subsequent repair work, in order of importance, around the needs of the client.
