Lincoln Center for the Performing Arts
LINCOLN CENTER TUNNEL
Relevance to the Current Proposal: This project involved the structural condition assessment of an existing structure to determine the cause of persistent water infiltration. This required analysis of the as-built drawings and hiring contractors to perform probes and exploratory openings. O&S was the engineer-of-record for the repair construction documents.
Summary: O&S was contracted to investigate several persistent leaks into an underground pipe access tunnel that runs from the Central Mechanical Plant under 65th Street to the Julliard School. Lincoln Center for the Performing Arts’ key concern for this project was for us to study all the various sources and building systems that were participating in the leaks.
Our team made exploratory openings to observe the actual as-built condition of the wall and flashings, and these observations were then used to determine how the walls were constructed. We also studied the moisture between the exterior walls, slabs, and foundation wall. After investigating all areas of the tunnel, it was determined that state-of-the-art solutions were required to eliminate water infiltration through the length of the tunnel.
O&S developed the required construction documents for concrete repairs and gel injection for all cracks and construction joints. The work was done while still maintaining occupancy, and by providing these services as expeditiously and as professionally possible to minimize the impact of the required repairs and the remediation work required. The project started in November 2014 and was completed in November 2015 with a cost of $900,000.
LINCOLN CENTER ROSE BUILDING
Completed in 1990, The Lincoln Center Samuel B and David Rose Building was designed by the architectural team of Davis Brody & Associates/Abramovitz-Harris-Klingsland and is clad in granite and limestone on all elevations. This 29-story building is home to the school of American Ballet, Juilliard School student residences; performance venues Walter Reade Theater, Stanley H. Kaplan Penthouse, Daniel and Joanna S. Rose Rehearsal Studio and Clark Studio Theater; and several Lincoln Center constituent offices.
The owner, in response to city mandated façade inspections for compliance purposes, came to O&S to provide the necessary scope of work, probable construction costs, and other project concerns. Our project team members are experts in façade restoration and experienced in determining accurate budgets for their repairs. O&S Associates performed a binocular investigation of all the building’s façades from the ground, adjacent buildings, and a lower roof. The repair program is inclusive of granite and limestone replacement and repair and 100% replacement of all building sealant. The project was successfully put out to bid and is currently in the construction with a projected cost of 3 million dollars. Construction started in January of 2017 and consists of 3 phases to meet the owner’s requirements and has an anticipated completion date of June 2019.
LINCOLN CENTER JULLIARD SCHOOL BUILDING
Completed in 1969, The Julliard School Building is clad in travertine on three elevations. During a recent expansion and renovation project, the Broadway elevation was changed to a glass-fin curtain wall. This six-story building is home to the school for performing arts and Alice Tully Hall.
The owner, in response to city-mandated façade inspections for compliance purposes, came to O&S when additional levels of certainty were needed with respect to the necessary scope of work, probable construction costs, and other project concerns. Our project team members are experts in historic façades and experienced in determining accurate budgets for their repairs. O&S Associates performed a forensic up-close investigation of the travertine clad elevations using swing-stage scaffolding and man lifts. We completed the documents for the restoration of the building façades at the request of the owner. Due to the porosity of the travertine stone cladding and water penetrates of the wall system, the original design does not provide a system to weep out. The repair program is inclusive of travertine replacement and repair and 100% building sealant replacement. The project was competitively bid and is currently under construction with a projected cost of 6.8 million dollars. Construction started in January of 2019 and consists of 3 phases to meet the owner’s requirements and has an anticipated completion date of November 2020.
