A Crack Team
Remediation of cracks and spalls in masonry and concrete is a key part of our practice. While we endorse immediate repair of all observed deficiencies, we’re intrigued by this artist’s approach to less serious conditions (while they await repair, of course).

An Ironclad Restoration: 31 Greene Street
Ludwig Mies van der Rohe said, “God is in the details.” SUPERSTRUCTURES’ restoration of 31 Greene Street (George W. DaCunha, 1876) in the SoHo-Cast Iron Historic District demonstrates how attention to restoration details at almost one hundred discrete locations creates a unified standout.

Pyramid Scheme
Plans to “restore” Giza’s pyramid of Menkaure by recladding its facade with granite blocks have stirred up a monumental debate. The available evidence, including original stones remaining at the base of the pyramid, indicates that the original “design intent” included polished Aswan granite cladding. But should the pyramid be reclad? The question is a redux of the dilemma constantly facing preservationists.

A Philosophical Challenge
SUPERSTRUCTURES' restoration of NYU’s Department of Philosophy Building (Alfred Zucker, 1891) posed two professional challenges to our team: to extrapolate, based on incomplete evidence, facade details that had been lost over time; and to decide where inappropriate past repairs to the facade should be reversed to recreate the building’s historic appearance.

Frost Jacking Day Tracker - 2023-2024 Season
SUPERSTRUCTURES is excited to launch the seventh season of the Frost Jacking Day Tracker. "Frost jacking" is what happens when freezing temperatures cause rain or snow to turn to ice and expand cracks in a facade. As cycles of freezing and thawing accumulate, the cracks continue to grow and exterior hazardous conditions or interior water damage or leaks can occur.

WHO Needs Drones?
The skies over New York City got a little wilder late last year when Flaco, a Eurasian eagle owl escaped the Central Park Zoo. City bird watchers may also start noticing Flaco’s mechanical counterparts: UAVs—drones—approved last year for building inspections across the five boroughs.

The “Pandora’s Box” of Sidewalk Vaults
A recent Habitat post characterized sidewalk vaults as a “Pandora’s box” of potential problems for building owners.  But that’s not the right analogy. In Greek mythology, Pandora was given a box as a gift from the gods but instructed not to open it. She couldn’t resist opening the box and out flew every evil that would henceforth plague humanity. But unlike Pandora’s box, you should enter or open vaults periodically to monitor their condition before problems escalate.
