1. Minimizing Air Carrier Impacts During Construction Phasing for Operations and Production 30 th Annual Airport Conference FAA Eastern Region March 8, 2007

2. 30th Annual Airport Conference FAA Eastern Region 2 Case Studies: Salisbury (SBY) Maryland – Runway 14-32 Overlay Roanoke (ROA) Virginia – Runway 6-24 Overlay

3. 30th Annual Airport Conference FAA Eastern Region Project Similarities  Intersecting runways  Only 1 ILS runway  Air carrier maintenance bases  Air cargo operations  Non-typical overlays: Grade correction, shoulders, new taxiways

4. 30th Annual Airport Conference FAA Eastern Region THE CHALLENGE FOR BOTH: Protect our Air Service! Minimize operational impacts AND Maximize construction productivity

5. 30th Annual Airport Conference FAA Eastern Region Easier Said Than Done! Advance Coordination Advance Coordination Legwork – Digging Into the Airline’s Operations Legwork – Digging Into the Airline’s Operations Several Iterations Several Iterations Compromise & Tough Decisions Compromise & Tough Decisions

8. 30th Annual Airport Conference FAA Eastern Region Airport Operations  One air carrier (HQ & maintenance base @ SBY)  PX service 5 am – 12 midnight x 7 days  Unscheduled maintenance flights  Daily late night “catch up” flight from PHL  Air cargo operations  Based MD State Police Medevac Helicopter

9. 30th Annual Airport Conference FAA Eastern Region Unique Project Features Aggregate supply issues Aggregate supply issues  Availability of paving contractors  Competition with local highway projects  Fewer sequencing constraints (access, work windows)  Fewer financial constraints (LDs, PWLs)  Easier than airports!  Heavy asphalt overlay (8”) w/grade corrections

10. 30th Annual Airport Conference FAA Eastern Region Advance Coordination  User meetings  All tenants  Air carrier only  Various airline reps – chief pilots, schedulers, local reps  ATCT meetings  Contractor meetings  FAA ADO coordination

11. 30th Annual Airport Conference FAA Eastern Region Legwork – Digging Into the Airline’s Ops  Finding the right people to talk to  Aircraft specific criteria for takeoff/landing  Airline specific policies for takeoff/landing  Date specific airline schedules  Areas of flexibility – aircraft types and schedules

12. 30th Annual Airport Conference FAA Eastern Region Several Iterations  Draft layouts & declared distance tables  Submittals to parties  Seeking & receiving feedback

13. 30th Annual Airport Conference FAA Eastern Region First Plan – No Impact Option  Work only on VFR days  8 pm call by Airport each night on whether runway available next day  Successfully used on previous safety area project  Intersection work “Midnight - 5 am” (airport closed)  Intersection work window = 5 hours  Received no bids

14. 30th Annual Airport Conference FAA Eastern Region Second Plan  30 day shutdown of ILS runway  Intersection work “Dusk - 5 am” (airport closed except for scheduled air carrier)  Air carrier ops accommodated dusk – midnight  Intersection work window = 9 hours +  Definition of dusk

15. 30th Annual Airport Conference FAA Eastern Region Crosswind Runway Use 3,200’ available 3,200’ available –Air Carrier Landings –Cargo and Maintenance Flights –No GA Pull Back from Safety Area Pull Back from Safety Area

16. 30th Annual Airport Conference FAA Eastern Region Phasing Layout

17. 30th Annual Airport Conference FAA Eastern Region Tough Decisions  To airlines – we cannot “not do” the project  To airlines – firm midnight cutoff  To GA – Restricted to Air Carrier Ops

18. 30th Annual Airport Conference FAA Eastern Region Conclusion  Successful project!  No flights cancelled due to construction  Completed within established milestones  Fewer nights required for intersection work  Using same approach for follow-on phase

21. 30th Annual Airport Conference FAA Eastern Region Airport Operations  4 Air Carriers, Maintenance base  Service 5:45 am – 11:30 pm  3 Air Cargo Carriers plus unscheduled  Financial & Medical Flights, GA  Football Charters

22. 30th Annual Airport Conference FAA Eastern Region Project Goals  Rehabilitative Overlay, 3 to 5 inches P-401  Transverse grade correction  New taxiways: ends, midpoint, fillets  New shoulders  Improve to standards to maximum extent

23. 30th Annual Airport Conference FAA Eastern Region Minimum Impact Schedule  Midnight to 5:30 am  Pull back for cargo ops  Project Duration: 2 years  Unacceptable  Brainstorm: All Options but “Protect Air Service”

24. 30th Annual Airport Conference FAA Eastern Region Finding Additional Work Hours  Flights after 9:30 pm are arrivals  Saturday nights after 8:30 pm  Crosswind runway considerations  Length  Terrain limited – One way  Winds

25. 30th Annual Airport Conference FAA Eastern Region Wind Analysis Air Carrier Landing Runway 33 Air Carrier Landing Runway 33  No tail wind allowed for jets  Air Cargo Depart Runway 15  Weight Penalty

26. 30th Annual Airport Conference FAA Eastern Region Wind Analysis Meteorological Data Meteorological Data  South and East Winds about 1/3 of the time in summer to fall  2/3 of the time we can get 2 hours more production, almost double

27. 30th Annual Airport Conference FAA Eastern Region Wind Based Contract Provision Planned start at 9:30 pm Planned start at 9:30 pm If tail wind, Start at 11:30 pm If tail wind, Start at 11:30 pm For each 2 late starts, add 1 contract and milestone day For each 2 late starts, add 1 contract and milestone day

28. 30th Annual Airport Conference FAA Eastern Region Advance Coordination  User meetings: Air Carrier primary  ATCT and Ops meetings: One voice  Contractor meetings – Input and preparation  FAA ADO coordination – Contract matters

29. 30th Annual Airport Conference FAA Eastern Region The Plan  Sunday thru Friday 9:30* pm – 6:00 am  Saturday 8:30 pm – 6:00 am  Intersection work Saturday nights  RW 15-33: 4,000 usable  *IF tailwind on RW 33:  11:30 pm start  contractor receives extra night & day for every 2 nights lost  Owner makes nightly call at 9pm  10 minute delay if “on final”

30. 30th Annual Airport Conference FAA Eastern Region Coordination Results  Compromises  Clear Rules of Authority and Limits  Contingency Items  What Ifs?  Be Ready

31. 30th Annual Airport Conference FAA Eastern Region Project Results  58,000 tons of P-401  On time completion even with 9/11/01  No air carrier diversions  Wind impact days – slightly less than projected

40. 30th Annual Airport Conference FAA Eastern Region Keys to Success  Seek the right people to talk to  Airline specific policies for takeoff/landing  Airline schedules & aircraft types  Find areas of flexibility – aircraft types and schedules

41. 30th Annual Airport Conference FAA Eastern Region Keys to Success  Must Do the Project!  Roll-up-your-sleeves work sessions w/airline schedulers  Contractor input on constructability  Commit: Airport-wind call, Airlines-diverts, Contract- stand by it, credibility

42. 30th Annual Airport Conference FAA Eastern Region Common Threads  Coordinate well in advance, seek key affected parties  Identify and engage the right people - priorities  Dig into the details of the airline’s operations  Remember that a little means a lot once contractor is mobilized  be creative, but keep it simple  be ready (Owner) to make the difficult decisions  Provide solutions to your ADO engineer, present analysis and justify
