    Utility Survey of Kill Van Kull, Newark Bay and Upper NY Harbor Utility Survey of Kill Van Kull, Newark Bay and Upper NY Harbor Presentation Transcript

    • Utility Survey of Kill Van Kull, Newark Bay & Upper NY Harbor J. R. Lemuel Morrison, PLS
    • Outline
      • Background
      • Process
      • Innovations
      • Results
    • New York Harbor
      • Modernize the channels that serve the local ports:
      • Kill Van Kull/Newark Bay Channels deepened to 45’ for access to Port Newark/Elizabeth.
      • Seven key channels deepened to 50’ over the next few years.
    • Reason for the Survey
      • Port Authority could not start design, much less planning, without specific data on the crossings. The number of crossings were not even known.
      • No single entity, even the USACE, had complete or current records--even the number of crossings.
      • The Port Authority needed to know:
        • What utilities cross the project area?
        • Who owns them?
        • Where they are?
    • Utility Survey – 3 Hurdles
      • The deadline: How to complete the work in a 4-month time period?
      • Utility survey process: How to find utilities underground, both by physical observation and by record information?
      • Representation: How to convey the vast amount of information not only to our client (who understands survey information), but also to design engineers, planners, politicians and others?
    • Meeting the Deadline
      • In a usual project the process is:
      • Tasks are done in order
      • One person at a time works on a drawing
      • There are a manageable number of documents
      • Two key differences:
      • Volume of documents
      • Compressed timeframe (which could not be extended)
      Conclusion: change work method Address tasks simultaneously Access same files concurrently
    • Resulting Work Flow
      • Tasks broken down by genre: notes, aerial mapping, utility lines, and layouts.
      • Linked documents and drawings together:
      • Additionally:
      • Held regular staff meetings
      • Scanned every document
      • Used xreferences aggressively.
      • Used OLE inserts for charts and notes
    • Utility Survey Process
      • Research Documents
      • Locate Surface Evidence
      • Interpret and Present Graphically
    • Research
      • United States Army Corps of Engineers (USACE)
      • Municipal Utility Authorities for the Boroughs of Bayonne, Elizabeth & Linden and for Hudson & Union Counties.
      • County Clerks of Hudson County, Union County & Richmond County
      • Bureau of Land Management at the New York Office of General Services
      • Division of Coastal Resources at the New Jersey Department of Environmental Protection
      • Private Utility Companies
      • New York City DDC
      • New York City DEP
      • New York City DPR
      • National Parks
      • National Archives
      • Borough President Offices
    • Document Example Source: NYCDEP
    • Locate Surface Evidence
      • How to locate underground utilities?  You can’t.
      • We can provide indications of the utilities by locating the surface evidence.
        • The process:
        • Set up a local network for aerial control and for Real-Time-Kinematic (RTK) base stations
        • Use GPS in RTK mode to locate surface evidence
        • Match located evidence to features in research documents
        • Digitize single-entity polyline for each utility
    • Representation
      • How to present this data? We supplied CAD drawings and prints.
      • Problems:
      • Massive data set. Thousands of documents.
      • More crossings than anticipated.
      • Data more complex than just a location. Questions of ownership, responsibility and time periods outside the jurisdiction of a surveyor.
      • Access to the data by third parties outside of the Port Authority.
    • Representation
      • Many solutions:
      • Every document was scanned.
        • This allowed easy transmission to the Port Authority, but also to others. It organized our operation and allowed more than one person to use the document.
      • Each crossing had an individual folder.
        • Everything for a crossing was in one electronic place. The engineers could see the data affecting the crossing.
      • E-plots were created of each drawing sheet.
        • Non-editable files could then be distributed to others. Yet the functionality of CAD remained.
    • Digital Folder Example
    • E-Plot Example
      • An e-plot is a format, similar to a PDF that is non-editable.
      • The format is read-only but retains CAD capabilities such as zooming and turning layers off and on.
      • E-plot format allows third parties to print the document and to add markups.

    • Conclusions
      • Surveys were completed on-time and under budget.
      • Surveys were exceptionally useful and I still get calls about the project. They were provided to utilities, planners and officials.
      • Surveys brought disparate data from many agencies together. Not only were the utilities located, but a descriptive data set was also created for each one.
      • Surveys expanded the traditional “deliverable” to a client. The end-user received not only an esoteric survey, but also a product that could be used again and again.
