The third time’s the charm for engineers NV5 and preservation consultants at Higgins Quasebarth & Partners. On February 5, the team, this time joined by stone conservation expert George Wheeler, successfully argued before New York’s Landmarks Preservation Commission (LPC) for permission to swap the stone out at the Manhattan plaza of the landmarked 140 Broadway building. The former Marine Midland Building, an international-style office tower designed by Gordon Bunshaft and SOM in 1967, is distinctive for how its imposing black massing “floats” above a plaza of what was originally travertine surrounding Isamu Noguchi’s distinctive Red Cube. The travertine pavers were replaced with pink granite in a 1999 renovation, and the project team went before the LPC to propose a new shade of granite closer to the original stone. That drew the ire of preservationists and some of the commissioners, who asked why travertine wasn’t being used instead. Much of the presentation (available here) from 140 Broadway’s ownership and project team dealt with that question. The pitch was that granite, with a compressive strength of nearly three times that of travertine, would be a much more durable replacement. Travertine’s pockmarked nature also renders it particularly vulnerable to freeze-thaw cracking and salt blooms because water easily impregnates the porous stone. The team maintained that five-inch-thick travertine pavers would be needed to meet all of their aesthetic and safety concerns, and that because of the voids under the plaza, the pavers can only be two-inches thick. While Bunshaft had chosen travertine to evoke the feeling of a Roman plaza, the presentation made it clear that New York’s climate was much harsher than Rome’s. The comprehensive analysis was done after the ownership team’s prior two LPC presentations in March and November of 2018. Commissioners had previously declined to vote on the proposed granite replacements and suggested that NV5 and Higgins Quasebarth look further into travertine. As preservationist Theodore Grunewald noted, the reason 140 Broadway’s plaza was before the LPC was that the granite installed in 1999 was also failing and that there was no guarantee that it wouldn’t happen again. Travertine plazas are still in use at Manhattan’s W.R. Grace Building and Solow Tower Building, both designed by Bunshaft, but the project team noted that the drainage systems and sloped “skirt” at the base of each tower helped facilitate the quick movement of water off of the vulnerable stone beneath. Ultimately the commissioners voted to approve the use of Tudor Gold Granite, although there were some concerns about the need to choose a color closer to the original travertine. Commissioner Adi Shamir-Baron, the only nay vote at the hearing, noted that the commission’s role was to preserve moments in time, regardless of viability, and not just upgrade the city’s properties with "space-age materials."

After hearing—loudly—from critics and community members, the team behind 140 Broadway's plaza revamp has revised its design for the outdoor spaces surrounding the former Marine Midland Building, SOM's landmarked 1968 corporate modernist masterpiece. Landscape architects at New York's NV5, in collaboration with preservation consultants at Higgins Quasebarth & Partners, have submitted a revised design for the modernist plaza at 140 Broadway to the Landmarks Preservation Commission (LPC) for a hearing next week. Most notably, the new design eliminates a 14-foot-wide planter at Broadway and Cedar Street that would have sat kitty-corner from the plaza's signature sculpture, Isamu Noguchi's Red Cube. Aside from the absence of the large corner planter, the plaza design is relatively unchanged from the one revealed in January. Like the previous scheme, the new plans call for six, 14-foot-wide circular planters that double as benches along Cedar Street. Meanwhile, the Helmsley Memorial, a blocky black-granite tribute to the late owner, will be re-dedicated as a marker flush with the pavement, and the design team will add metal bollards along Cedar. To further harmonize the space, the design team is replacing pinkish granite pavers installed in 1999 with a light golden-hued granite that resembles the original travertine plaza. When the plaza plans were revealed in January, critics panned the design, saying it would distract from the Noguchi sculpture, which was installed to complement the plaza and its 57-story tower. Originally, the LPC was scheduled to hear the plaza plans in early February, but public debate over the appropriateness of the renovation prompted the designers and owner to withdraw the item from the LPC's calendar. The Architect's Newspaper (AN) obtained an advance copy of the plans that were submitted to the LPC. All the renderings and drawings pictured here are from that document. Jackson Wandres, director of landscape architecture at NV5, and Erin Rulli, partner at Higgins Quasebarth, said that their overall goal is to add more seating and re-establish the east-west viewshed that extends from Zuccotti Park across the 140 Broadway plaza and over to SOM's 28 Liberty (formerly One Chase Manhattan Plaza), a modernist skyscraper of the same vintage. The 140 Broadway plaza "is the knuckle in a series of open spaces," Wandres said. "It makes the space feel much larger." A web of fine-toothed zoning designations divides these three seemingly unified areas and complicates the design intervention, however. The park and the two office tower plazas are POPS, spaces that are privately owned and maintained but free for the public to use. At 140 Broadway, the plaza continues out from the building to the edge of the roadway uninterrupted, even though the property line actually ends about 20 feet before the street; the food carts with LED marquees that sling chicken-over-rice and green juice to hungry passerbys sit on the public right-of-way. By obstructing the historical plaza-to-plaza vista, "the carts have caused a dramatic shift in how you experience the space," Rulli said. "It's not the intention to deprive anyone of their livelihoods, but rather, it's a design move for the benefit of the plaza," Wandres added. The pair clarified that any changes to the public area is under the Department of Transportation's (DOT) jurisdiction, not owner Union Investment's. Consequently, the proposed food cart–replacing benches and planters in the right-of-way are being reviewed by the DOT, not the LPC.
