Construction Monitoring for New York Presbyterian Hospital Ambulatory Care Center
New York Presbyterian Hospital Ambulatory Care Center
New York, NY
New York Presbyterian Hospital
AKRF is providing construction monitoring for New York Presbyterian Hospital’s future Ambulatory Care Center on Manhattan’s Upper East Side, including a pre-construction survey assessment, a monitoring program during construction activity, and a final post-construction program for eight properties on and adjacent to the project site.
Construction of the New York Presbyterian Hospital Ambulatory Care Center (NYPH ACC) began in August 2014, and will include demolition of the existing buildings and construction of a new building.
AKRF’s construction support services for this project include:
- Preparing an overall visual assessment of the state of the building’s structural elements and façades, both interior and exterior
- Researching relevant building/site violations per information obtained from the New York City Department of Buildings and the Environmental Control Board
- Providing and installing crack monitors for areas of concern identified in the pre-construction survey, and recording data throughout the duration of demolition and heavy construction activity
- Conducting a noise survey to find background noise level measurements at the project site representative of baseline noise levels at adjacent sensitive noise receptors; these measurements provided a baseline with which to compare noise levels that may occur during construction of the NYPH ACC
- Providing a noise monitoring program within the Memorial Sloan-Kettering (MSK) Zuckerman Research Center immediately adjacent to the site
- Developing a vibration monitoring program for numerous locations throughout the eight buildings surrounding the construction site; AKRF worked with the structural engineer, construction staff, and building management staffs to develop this program
Both the noise and vibration monitoring programs utilized remote telemetry intended to alert construction staff when noise and vibration levels reached or exceeded action thresholds. The noise monitoring program also assisted in communicating the expected magnitude and duration of construction noise associated with each type of activity.
In addition to the continuously operating remote vibration monitoring points, AKRF conducted a targeted vibration survey for sensitive medical instrumentation, including MRI scanners, operating in the MSK Zuckerman Research Center immediately adjacent to the construction site. This survey, which used an FFT spectrum analyzer, evaluated the peak levels of construction vibration and compared them to manufacturer’s specifications as well as typical vibration assessment thresholds to determine the effects of construction vibration on operation of the equipment.
During caisson drilling operations on the construction site, to which the adjacent building staff was particularly sensitive due to noise and vibration concerns, AKRF provided full-time staff at the construction site with additional vibration monitoring equipment. AKRF’s on-site inspector logged construction activities so they could be correlated with recorded vibration levels on-site and within the adjacent buildings, as well as placing the vibration monitoring equipment such that it monitored worst-case caisson drilling operations each day.
AKRF will provide a final inspection upon completion of construction activity.
