New Data Management for Projects

All Project Survey, Planning, Design and Decision Making Data is Stored for Many Projects and Massive Amounts of Data Including:Citizen Reported Data

Storm Event Data, Known System Deficiencies & Failures

Previous Maintenance Projects or Repairs

Survey Data

Engineering Analysis and Results

Data is Managed for:Ease of Access for Engineers, Designers, Reviewers, Managers

Supplement to Hard Copies

Provide Quick Response to Residents and other Stakeholders

Provide Digital Location for Future Reference.

PROJECT DRIVEN REQUIREMENT

Step 1: Identify the Issue Massive Amount of Data Multiple Phases and Long Project Duration Many Users of Data

Step 2: Simple Solution to Manage Data Change Effort , but do Not ADD Effort Take Advantage of Geo-Referenced Data Make Available for Multiple Users Make Accessible and Formatted for Multiple Phases of Project (ie: Planning,

Design, Construction…..Beyond)

Step 3: Deliver the Data No Complex, Customized and or Costly Interface or Tools Accessible as Single .MXD file with Data Stored on External Hard Drive from any

Workstation. (Could be Copied to Network) Keep it Simple…..We Needed it Anyway

RESULT: Simple Supplement to Hard Copy Deliverable to Manage Large Amounts of Diverse Data in a Customizable , Visual Manner to Ease Access for Many Users Throughout Multiple Phases of Project and for Entire Project Duration
