Timeline, cost and logistics of a project can be significantly impacted if a proper assessment is not performed. A proper assessment should include: Identification of current conditions. Full documentation of the sidewalk should be performed before any work begins. Confirm if there are any interior leaks reported that Owner believes are due to current sidewalk conditions. Confirm all encroachments (fire hydrants, light poles, street signs, manholes, etc.) NYC regulations, Construction Codes and Zoning resolutions establish building element intrusions that are permitted as-ofright.....these require special approvals or are prohibited. ADA Compliance -NYC reached a settlement agreement with the Center for the Independence of the Disabled (and additional Plaintiffs). This settlement required curb cuts that discharge to the crosswalk. Accordingly, it’s important that you understand the difference between a Standard or Complex Corner. Identification of underground utilities or vaults. If your sidewalk has a Con Ed Vault, your will need prior approval, and a Letter of Acknowledgement before permit approval. DOT approval required together with vault logistics. Certain locations require BID approval.

Getting sidewalk permits is a process and an experienced expediting team is a MUST! At minimum....expect to meet the following requirements:

Board of District Approval Bike Rack
Removal Approval DOT Appointment to review project for prelim. approval
DPL-1 Form by RDP
DOT Vault Approval Con Edison Vault Filing & Letter of Acknowledgement
DOB Approval / DOT Approval
Budget 12-16 Weeks for all Approvals
MTA Meter Coordination for Standard, Comm. Vehicles and FHV.
HIQA Package for Pedestrian Ramps
DOT Permit Types are issued base on requirements and include many stipulations that must be observed or violations will be issued.
Coordination with DOT Events and Parades

A sidewalk replacement project is expensive! If you are undertaking a project that is as sizable as a Sidewalk Replacement Project, you will definitely want to make sure you include proper testing of the waterproofing.
High Voltage Leak Detection should definitely be a consideration. During testing, a high voltage brush sensor makes direct contact with the membrane and can reliably detect breaches in the membrane thereby allowing Contractor to ensure the new membrane is water-tight and give Owners the confidence that leaks will not present themselves after the concrete has been poured.
If structural vault work is required, you will want to ensure you have proper third-party inspectors signed on for structural steel high-strength bolting, post installed anchors, sprayed on fire resistant materials, etc.
Water testing may also be recommended where the facade transitions to the curb. This is usually accomplished with calibrated spray nozzle for 20-30 minutes.

Waterproofing manufacturer compliance requirements should be thoroughly understood and strictly followed to ensure warranties are not compromised.
Besides encroachments.....have you figured out how to move your friendly food cart if he vends from your sidewalk?
Concrete Pours involve concrete trucks that may impedes thru-traffic. Make sure you notify neighbors and plan accordingly.
Contractors should prioritize housekeeping and maintain a clean site at all times with all permits posted and prominently displayed. If the site has a pedestrian walkway 5' clearance should be maintained at all times.
If Flag Persons are required, contractor should ensure that they have completed DOB approved 1-hr. flag person training. Additionally, they should be uniformed and have the ability to speak English.
Check contractor experience and references & make sure your engineering team has the experience that focuses on Active Sidewalk Design

If the Building is Landmarked or in a Landmark district, you will need LPC approval.
If you have a distinctive sidewalk (granite, cobble stone, etc.) you will need additional approvals from either the Board of Standards, or the BID.
