Electronic Engineering Data• Initiative of FHWA’s Every Day
Counts (EDC) Program (see handout)• Files will be delivered at advertising
along with contract documents at the State Contracting Portal
• For pilot project, both native data and converted data will be provided in 2 separate zip files

Electronic Engineering Data Con’t• Native Data/Converted Data:
– InRoads 3D Digital Terrain Models with features (.dtm/LandXML)
• Existing Surface • Proposed Top Surface• Proposed Subgrade Surface
– Coordinated Geometry Alignment Data (.alg/LandXML)
– CADD MicroStation Design Files (.dgn/dxf)– InRoads Storm & Sanitary Drainage Data
Base (.sdb)– InRoads Preference file (.xin)
• Contract documents still preside

Uses/Benefits of EED• Bidding - more accurate bids• Automated Machine Guidance (AMG)
– Reduced Staking Costs – Lower Fuel Consumption and Emissions – Greater Accuracy / Higher Quality Product – Safer Work Environment– Reduced Schedules
• Intelligent Compaction• CADD files available for Contractor’s
use

Uses/Benefits of EED cont.
• Field preparation• Estimating• Real Time GPS Rovers:
– Field Layout– Verification– Quantity Measurements– As-built creation– Features easily located (northing-
easting-elevation or station-offset-elevation)

ACORN - Advanced Continuously Operating Reference Network
• Joint venture between CTDOT & UCONN
• ACORN is a system of 9 base-station receivers that stream real-time observations to give centimeter-accuracy positions
• Available for free (2014). Register at acorn.uconn.edu
• Nominal fee after 2014
