High-Capacity Formwork for Self-Consolidating Concrete

New York, New York

Hudson River Park Improvements

Hudson River Park is a unique and vibrant public park stretching along Manhattan’s west side, running from Battery Park City in the south to 59th Street in the north. The park covers 550 acres (223 hectares) of land and water and is one of the largest open spaces in Manhattan.

Construction of the Gansevoort Peninsula

The Hudson River Park Trust is a public benefit corporation established in 1998 that oversees the park’s planning, design, and operation. The Trust works closely with community groups, elected officials, and other stakeholders to ensure that the park meets the needs of its visitors and remains a vital resource for the city. The Trust is responsible for constructing new features and preserving existing ones, the most recent being the Gansevoort Peninsula.

Public Park on the Hudson River Waterfront

The Gansevoort Peninsula is a 5.5-acre (2.2-hectare) tract of land on the Hudson River waterfront in Manhattan, New York City. The construction of the Gansevoort Peninsula is a complex project that involves extensive planning, design, and engineering. The site has a long history of industrial use, and the project team had to carefully consider environmental factors and site conditions as they designed the area.

Looking for a Formwork Partner?

Why Choose Anyone Else?

Padilla Construction Services of New York were contracted to construct two buildings. They conducted qualification tests as part of their due diligence to secure the best formwork partner. The concrete design for both buildings required a formwork liner with some incredibly challenging characteristics. The pattern of the desired formwork liners was so intricate and detailed that the contractor was forced to use self-consolidating concrete to achieve the required finish. Self-consolidating concrete (SCC) is extremely flowable and can spread into place without vibrating the concrete. For this application, the concrete would be able to fill all impressions of the liner achieving the desired pattern. Additional challenges with SCC include a longer set-up time when inside the form, and because of this, placing a full liquid head of concrete is required, which increases the pressure of the concrete inside the formwork.

Self-consolidating Concrete for Formwork Liners

Per Padilla’s contract, a mockup utilizing SUPER PLATE GIRDER® with their formwork liner was required to see how the self-consolidating concrete performed with the formwork liner. The results of the pour proved to be successful. The maximum pour height was on the maintenance and operations building, reaching 15′ (4.6 m) and 5″ (125 mm) with a pour pressure of 2,320 lb/ft2 (111 kPa) for a full liquid head pour. The form’s strength and requirement for fewer ties than other options allowed Padilla to choose EFCO as their formwork partner confidently.

Shoring of Elevated Concrete Slabs

A unique feature of the concession and maintenance buildings is that the roofs would also serve as a green roof canopy system, a natural water retention system. This natural water retention system provides environmental benefits and enhances the buildings’ aesthetic appeal. EFCO provided the E-Z DECK® shoring and decking system to shore the elevated slab construction for the slanted roofs. Utilizing EFCO’s swivel head, the contractor achieved the required slope to each building’s design requirements.
