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

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

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
