Common Questions
What is a construction monitoring plan?
A monitoring plan is a PE-prepared document specifying the instruments, locations, thresholds, and response procedures required to protect adjacent structures during nearby construction activities.
When is a monitoring plan required by the NYC DOB?
Monitoring plans are typically required when excavation, underpinning, or demolition occurs within a specified distance of occupied buildings or structures protected under NYC Building Code 3309.
How long does it take to prepare a monitoring plan?
Turnaround depends on project complexity and site conditions. Liberty prioritizes timely delivery to ensure your monitoring plan is ready well before your scheduled construction start date.
Does the monitoring plan need to be filed with the DOB?
Yes. The PE-sealed monitoring plan must be submitted to the NYC Department of Buildings as part of the pre-construction compliance package before regulated activities commence on the project site.
Can Liberty prepare the plan and perform the monitoring?
Liberty handles both plan preparation and ongoing field monitoring, ensuring seamless continuity between the engineered plan requirements and the instruments and reports produced on site.
