East River Waterfront Esplanade and Piers


The NYCEDC retained a joint venture team for a $135 million project to improve access to the East River Waterfront, increase pedestrian connectivity and produce major waterfront services for public use/enjoyment. HAKS led the survey team selected by the joint venture to perform a land survey and prepare a topographic, right-of-way and utility base map of 2 miles of the waterfront.

State-of-the-art techniques included a primary control network tied to the borough of Manhattan datum; photo control targets established by GPS; aerial photogrammetry for aerial skeleton base mapping; a supplemental conventional survey under the FDR Drive; and vertical clearance under the FDR Drive measured by a reflectorless total station.

Base mapping included a combined aerial and supplemental conventional survey to prepare a topographic base map; digitized all subway tunnel alignment within the project area; and digitized utility and right-of-way maps to prepare a comprehensive project base map. A comprehensive base map of the project was delivered in 15 weeks and we provided progress drawings to help the joint venture team commence work early.

Scheduling and coordination included coordination with the joint venture, NYCEDC and all private and public utility companies/agencies; an aggressive 15-week schedule; project management, critical path scheduling and quality control procedures leading to efficient project mapping; and concurrent supplemental survey and aerial mapping.

The horizontal coordinate system and vertical datum adopted for the project were based on monuments and benchmarks established by the Borough of Manhattan President’s Office.

The project received the ACEC-New York Platinum Award for Engineering Excellence.
