GYBVNT NSAP-DLA-45-Elevator Pit Clearance

This project is to bring the building 45 elevator up to code. According to ASME A17.1 Section 2.4.2, counterweighted elevators must maintain a minimum bottom run-by clearance of 6 inches between the lowest point of the counterweight (including any buffer compression or over travel) and the pit floor. This clearance is critical to prevent mechanical interference and ensure safe deceleration during emergency stops or failure conditions. A review of the elevator system indicates this requirement may not have been met, which could pose a safety hazard and result in code noncompliance; the counterweight bottom run-by clearance of Building 45's elevator is only 4 inches. Remediation is necessary to bring the system into alignment with ASME standards. The proposed work involves evaluating the existing counterweight buffer system (spring or hydraulic), verifying actual stroke length, and determining available pit clearance. Corrective actions may include adjusting the elevator's travel limits, modifying or replacing the buffer system, or implementing mechanical alterations to ensure that the counterweight cannot descend below the required 6-inch clearance. All modifications will be followed by testing and inspection to verify compliance with ASME A17.1 2.4.2. This work will be contracted out; Environmental Construction Services Inc. (ESCI) is the contract awardee and will most likely subtract Pinus to perform the work. The scope of work will involve a thorough evaluation of the counterweight and buffer system to verify compliance with ASME A17.1 2.4.2. This includes: - Inspecting the existing buffer type (spring or hydraulic) and measuring buffer stroke - Measuring the actual clearance between the counterweight at its lowest point and the pit floor - Determining whether the travel li ...
