A MIXED-USE PROJECT IN NEW JERSEY

 

Foundational Challenges and Flat Slab Expertise

Client:  Green Property, LLC

Sector:  Commercial & Residential

MIXED-USE ENGINEERING

The latest project in our ongoing relationship with Green Property, LLC is a mixed-use building, combining commercial and residential spaces in Weehawken, New Jersey.  A five-story light gauge metal building with a two-story parking garage, the project has  one full story below grade, necessitating significant attention to retaining walls and the overall impact upon neighboring properties. 

SAFEGUARDING EXISTING STRUCTURES

AAES was responsible for all the structural work—foundations, slabs, retaining walls and underpinning. With existing buildings on two Sides, we had to ensure that surrounding structures were stable and underpinned properly, as well as avoiding over-excavation of the project site.

FLAT SLAB COMPLEXITY

A flat slab is a two-way reinforced concrete slab that works without beams and girders. Instead, loads are transferred directly to the  supporting concrete columns. Many engineers refuse to design for flat slab construction, deeming it too complex. For a building that’s uniform throughout every floor, flat slab engineering can be relatively straightforward. However, most mixed-use buildings entail custom spans and uneven column spacing— that’s where complexity proliferates. 

BENEFITS OF FLAT SLAB CONSTRUCTION

Despite inherent engineering challenges, flat slab has undeniable strengths when it comes to construction cost and functionality. Without protruding beams, utilities can run from one end to the other without interference, optimizing their performance. The technique 
also adds volume and headroom to a space, which increases value.

TRUST AND INNOVATION

Due to AAES’ ongoing partnership with this valued client, they trust us to make bold recommendations on their behalf, and to vouch for their safety. In this case, the original vision for the property involved traditional construction with joists at every level and bearing walls every 12 feet. We convinced our client to build the upper levels as metal decks with only lightweight concrete slab and bearing walls, resulting in a far more open and versatile space, plus a 60% cost savings on steelwork.
