Structural Support You Can’t Afford to Ignore
4D Construction specializes in the construction and reconstruction of sidewalk vaults, critical structural elements found throughout New York’s urban infrastructure. These below-grade concrete chambers must be strong enough to support pedestrian traffic, vehicles, and building systems while providing a safe and dry space beneath the sidewalk surface.
Whether your vault needs full replacement or targeted structural repair, we bring the experience and precision required to meet building codes, DOT standards, and architectural demands.
Our Sidewalk Vault Services Include:
Full Vault Reconstruction - Demolition and rebuild of aging or failed sidewalk vault structures.
Structural Slab Installation - Reinforced concrete slabs to support traffic and equipment above.
Shoring and Temporary Support - Engineered support during construction to prevent structural compromise.
DOT and DOB Coordination - We manage permits, inspections, and engineering for full compliance.
