b'12 SFOTAXIWAYSFAA and airfield lighting required new duct bank infrastructure.It required closing taxiways A and B, the two main arterial taxiways that encircle the terminals. In addition, Runway 28L was closed for landings and takeoffs and instead used as a detour taxiway to navigate aircraft around the work area. All aircraft arriving or departing SFO need to travel along these two ring taxiways, Summers explains. Therefore, phasing the works to maintain the functional circulation of aircraft was key in allowing construction to progress but also to ensure aircraft could still navigate around the work area when taxing to and from the terminals.Moving aircraft around the work area required thorough planning taxiing well as cooperation from SFO, airlines, pilots and as air traffic controllers. Strong coordination was key to our success, as it ensured there were no safety operational risks, Lee remarks. We had no safety incidents throughout the entire six-month period.Another hurdle for the project was the impact on passenger operations when Runway SCAN TO BOOST EFFICIENCY AMID CHECK OUTOUR FULL LINE WORKFORCE CHALLENGES OF AIRPORTPRODUCTSPREMIUM PRODUCTS, IMPROVED EFFICIENCY, LESS MAINTENANCE/DOWNTIME Graco Line Striper Low Profile Barricade No Tools NeededRunway Closure Markers800.525.8876 | WWW.SHERWININDUSTRIES.COMContract # 110122-SWNOctober 2024AirportImprovement.com'
