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

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

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

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

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

  6. CASE STUDY #1 Salisbury-Ocean City: Wicomico Regional Airport Runway 14-32 Overlay 30th Annual Airport Conference FAA Eastern Region

  8. 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 30th Annual Airport Conference FAA Eastern Region

  9. Unique Project Features • 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 30th Annual Airport Conference FAA Eastern Region

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

  11. 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 30th Annual Airport Conference FAA Eastern Region

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

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

  14. 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 30th Annual Airport Conference FAA Eastern Region

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

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

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

  18. 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 30th Annual Airport Conference FAA Eastern Region

  19. CASE STUDY #2 Roanoke Regional Airport Runway 6-24 Overlay 30th Annual Airport Conference FAA Eastern Region

  20. 30th Annual Airport Conference FAA Eastern Region

  21. 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 30th Annual Airport Conference FAA Eastern Region

  22. 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 30th Annual Airport Conference FAA Eastern Region

  23. 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” 30th Annual Airport Conference FAA Eastern Region

  24. 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 30th Annual Airport Conference FAA Eastern Region

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

  26. Wind Analysis • 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 30th Annual Airport Conference FAA Eastern Region

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

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

  29. 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” 30th Annual Airport Conference FAA Eastern Region

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

  31. 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 30th Annual Airport Conference FAA Eastern Region

  39. 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 30th Annual Airport Conference FAA Eastern Region

  40. 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 30th Annual Airport Conference FAA Eastern Region

  41. 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 30th Annual Airport Conference FAA Eastern Region
