1 DFW Connector Design-Build Success Story Presented to the American Association of State Highway and Transportation Officials Sam E. Swan, P.E. August 2, 2011

2 Developer: NorthGate Constructors $1.02 billion design-build project Contract executed October 6, 2009 Work began Feb. 17, percent of contract earned ($396 million of $931 million in construction as of May 2011) 37 percent of schedule completed (622 out of 1,702 days as of May 2011) Estimated completion: 2014 Project Overview

3 City of Grapevine City of Coppell Town of Southlake City of Colleyville SH 121 FM 2499 SH 26 SH 114 SH 121 SH 360 SH City of Irving DFW International Airport Project Overview Tarrant County Dallas County City of Grapevine City of Coppell City of Colleyville City of Irving City of Euless Town of Flower Mound Town of Southlake D/FW International Airport DART The T RTC & NCTCOG FHWA FAA USACE Grapevine Mills Mall Bass Pro Shop Gaylord Texan Baylor Hospital

4 Project Overview

5 2011 Work - Current 16 bridges under construction simultaneously –Major direct connectors: Eastbound 114/121 to 121 north, northbound 121 to westbound 114, eastbound 114 to southbound 121 First new permanent pavement opened in temporary configuration, late 2010 Utility relocations ongoing North Entrance at DFW Airport –Keeping traffic moving into third-busiest airport in the world

6

7 Innovations Used Design Task Forces –Weekly meetings –Best technical solutions –Designer/contractor/owner-TxDOT/stakeholder participation –Coordination between design and construction

8 Phasing of the Project –Started during the procurement –Focused on: Maintaining existing capacity Creating large efficient work areas Minimizing full freeway closures Minimizing ROW and Utility conflicts Creating work areas unaffected by traffic Creating temporary configurations better than existing –Organized by block: Break the mega-project into manageable pieces. Innovations Used

9 Block Phasing

10 3-D Design –Better visualization –Identify and eliminate conflicts –Tied to our P6 schedule with Synchro –Able to download directly into our GPS controlled equipment Innovations Used

11 Construction –GPS grade control equipment –Conduits for water and lime into the median –Electronic tracking of equipment, trucks and materials Innovations Used

12 ProjectOne –Microstation and InRoads files organized by discipline –Effectively find and view files and project- specific training videos

13 Innovations Used Microstation/ InRoads –Integrates tools specifically designed for quantity takeoffs, work plans, strip maps, and more

14 Innovations Used InRoads corridor modeler 3D view of model components

15 Innovations Used Trimble Business Center –Directly imports model data and converts to machine control files

16 Innovations Used Trimble Business Center –Used to visualize data, assist and help "QC" (quality control) the model –Models loaded into "rovers" and installed on equipment –Excavators –Dozers –Blades

17 Innovations Used Quantity Takeoffs

18 Innovations Used 3-D Quantity Takeoffs

19 Innovations Used Truck and Material Tracking

20 Innovations Used Trakit GPS –Mobile devices placed in trucks Ability to see the location of the trucks in real time Ability for managers to track cycle times and look for bottle necks

21 Innovations Used Material Tracking –Integrated suppliers Integrated electronic tickets –Weight reconciliation NorthGate owned and operated truck scale Material trucks weighed once they leave the quarry and again when they arrive at NorthGate –FiveCubits - Kiosk Overview.ppsxFiveCubits - Kiosk Overview.ppsx

22 Innovations Used Unattended Weighing Systems

23 Innovations Used Wireless Paving –Leica GeoSystems First used by Kiewit in 2003 Eliminates wire or string line Improves access and safety

24 Innovations Used TxDOT Field Technology –IPads/Tablets Verify paperwork, inspections, quantities in the field Timely Shorter review times Eventual GPS link to design documents Onsite verification of field work as designed

25 Innovations Used Track Mounted Crushing Equipment –Mobile Crushers All crushed materials to be used as base material for concrete paving Reduced trucking cost

26 Innovations Used Concrete Batch Plant

27 Public Information –Mobile App (in development, first for TxDOT) –E-alerts, weekly/monthly project updates –Business owners’ task force –Business access coordination –Project website stats (May 2011) 241,492 total visits (high of 41,081 visits in January 2011) 693 average daily visits (high of 1,325 average visits, January 2011) Innovations Used

28 Stakeholders affected by the DFW Connector: Benefits of a PI Team on a design- build project: Tarrant and Dallas County Cities: Grapevine; Southlake, Irving, Coppell, Colleyville, Euless, Flower Mound D/FW International Airport DART The T RTC & NCTCOG FHWA FAA USACE Grapevine Mills Mall Bass Pro Shop Gaylord Texan Hotel Baylor Hospital 300,000 daily commuters Business community Onsite-integrated team –Owner led with close interaction from TxDOT –Attend weekly meetings –Obtain up-to-date schedule/design information Sharing information –Share quickly changing information with stakeholders in a timely manner –Assists with their planning –Know what’s coming Community partnering –Maintain a presence within the community Timely mitigation of issues Public Information

29 Documented public feedback since December 2009 through April 2011: (percentage of complaints vs. commendations) Complaints: 61% Commendations: 39% Percentages flipped in last few months as construction has intensified Public Opinion

30 DFW Connector Project TxDOT-NorthGate Partnering

31 Partnering between NorthGate and TxDOT started before construction Open door policy Open and transparent communication Weekly discipline task force meetings between NorthGate and TxDOT Working Together

32 Independent facilitator with quarterly meetings Proactive vs. reactive approach Participation from all project personnel – TxDOT and NorthGate Identify issues needing escalation Task Force Partnering

33 Quarterly activities: –Project survey to assess the success of agreed upon goal areas –Review and revision of individual task force action plans –Analysis of “rocks in the road” Identify issues needing escalation Task Force Partnering (con’t.)

34 Issues identified and handled quickly before they become larger issues Issues follow a standard project escalation method Weekly task force leaders meeting to identify potential areas of concern Issue Resolution

35 Senior project management –NorthGate –TxDOT –FHWA Issue identification and partnering from a senior level Executive Partnering

36 Project Quantities - Fun Facts 2.1 million cubic yards of embankment (dirt) –Would fill the Dallas Cowboys stadium 20 feet deep 1.6 million square yards of concrete paving –170 times the area of the American Airlines center 130,000 linear feet drainage –400 times the length of a football field

37 Additional Project Quantities 600,000 square yards of concrete removed 550,000 square yards of asphalt removed 47 bridges 380,000 tons of asphalt 740,000 square feet of Mechanically Stabilized Earth (MSE) walls 2.9 million cubic yards of excavation
