  1. Electronic Engineering Data (EED) for Construction Introduction Architecture, Engineering and Construction Applications (AEC) Bill Pratt Ron Tellier Greg Sardinskas Highway Design Steve Hall Handout/AEC Webpage EED Description Delivery Uses/Benefits ACORN – Base Station Network

  2. Seymour RoundaboutState Project No.0124-0162 • Routes 188/334/Holbrook Road • Rotary upgrade to Roundabout • Full depth reconstruction, minor drainage • ADV 07/16/2014, Construction Spring 2015

  3. 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

  4. 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

  5. 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

  6. 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)

  7. 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

  8. ACORN BASE STATIONS May be partnering with NY, MA & RI in the future for better coverage along state borders/shoreline
