OMH Nathan Kline Institute Elevator Modernization and Associated Hazmat Abatement

This project consists of the comprehensive modernization of three elevators, including two three-stop bore-hole hydraulic passenger elevators and one two-stop bottom-traction freight elevator. The two passenger elevators will be converted to holeless hydraulic systems, with work involving pit floor lowering, new sump pump pits, upgraded elevator controls, hydraulic piping and pistons, pit steel, buffers, and guiderails. Hoistway entrances will be reconstructed with new doors, frames, and sills, and each car will receive a new platform and sling, updated shell, interior finishes, lighting, and a modern control panel featuring audio and text-based emergency two-way communication and firefighter operations. One elevator’s mechanical room will also be enlarged and rebuilt with a new door to support the upgraded equipment.

The freight elevator will be transformed into a machine-room-less (MRL) traction elevator. This portion of the work includes lowering the pit floor, constructing a new sump pump pit with underpinning of the existing footing, and installing a new elevator controller along with a rail-mounted traction hoisting machine in the overhead space. New pit steel, buffers, guiderails, and modernized hoistway entrances will be provided, and the elevator car will be fully updated with a new platform and sling, enhanced interiors, lighting, and a control panel equipped with audio and text-based emergency two-way communication and firefighter functionality.

All elevator lobbies will be refreshed with new hall call stations and position indicator fixtures, along with patching and painting throughout. The General Contractor will be responsible for all hazardous material abatement, structural and architectural modifications, and core elevator work required to complete the modernization program.

To support these upgrades, the Electrical Scope includes providing electrical power enhancements, new lighting and receptacles, upgraded power feeds for equipment, and fire alarm system modifications for all three elevators. The HVAC Scope includes installing new split-system air conditioning units with outdoor condensing units in each of the three machine rooms, along with associated BMS system updates. The Plumbing Scope includes furnishing and installing new elevator pit sump pumps, discharge piping, fire protection system modifications, and related BMS updates serving each of the three elevator modernizations.
