Project Overview:

This project involved the structural and MEP fit-out of a landmarked building in Greenwich Village, transforming two existing floor plates into a functional house of worship. The work required careful integration of new systems within a complex, historically significant structure while maintaining its architectural integrity. Extensive analysis, field verification, and coordination were undertaken to adapt the existing building to new occupancy requirements, resulting in a cohesive and buildable solution that supports modern use within a constrained landmark environment.

Project Highlights:
  • Performed full structural analysis of existing floor framing to accommodate increased live load requirements for change in occupancy
  • Designed targeted reinforcements including welded steel plates and sistered cold-formed members to meet strength and deflection criteria
  • Created new slab openings for elevator and stair access within existing structure
  • Designed rooftop dunnage system integrated with existing building constraints
  • Executed full MEP design including new HVAC systems, domestic water service, and sanitary connections
  • Coordinated high-density plumbing layout including ablution areas and public fixtures
  • Conducted extensive field verification and record drawing review to address undocumented existing conditions
  • Managed LPC compliance for exterior modifications including louver integration
  • Secured MTA adjacency approvals due to proximity to subway infrastructure and cellar easement
  • Served as Structural and MEP Engineer of Record and Applicant of Record with full DOB filing responsibility
Project Experience:

This project demonstrates the firm’s ability to execute complex structural and MEP work within a fully landmarked and occupied building. The scope required careful analysis and coordination to adapt an existing structure with limited documentation to a new occupancy with increased loading demands. Through detailed engineering, field verification, and close collaboration with the design team, the project was developed into a practical and buildable solution.

The work involved evaluating and reinforcing existing structural systems to meet updated live load requirements, introducing new vertical openings, and integrating rooftop structural elements, all while maintaining the integrity of the original building. In parallel, full MEP systems were designed and coordinated to support the new use, including high-density plumbing layouts and complete system replacement. The team maintained continuous involvement from design through filing and into construction, ensuring that the project was executed accurately within the constraints of a landmarked property and active building environment.

Project Overcome:

The project is progressing toward the delivery of a fully functional house of worship within a landmarked building, supported by a coordinated structural and MEP design that meets modern code and performance requirements. Ongoing work includes adapting the existing structure to accommodate increased live loads and new vertical circulation while maintaining structural integrity.

Through targeted reinforcements, continued load path coordination, and integration of new building systems, the design is being implemented as a durable and constructible solution within a constrained and complex environment. The team remains actively involved through construction, ensuring that the work proceeds in alignment with design intent, regulatory requirements, and site conditions.
