![]() Travelers will soon have a tool to help them navigate indoors at SFO. While the FAA focuses on GIS use for detailed awareness of the horizontal infrastructure-runways, taxiways, pavements-SFO saw an additional opportunity to apply GIS to the interior to support facility management operations such as construction, maintenance, emergency response, and space planning. It was the first airport in the Western Pacific Region to receive a grant from the FAA to achieve compliance using GIS. The FAA’s move to NextGen is what prompted SFO to adopt GIS technology. With the better maps and sensors of NextGen, the FAA can guide aircraft more precisely and free up airspace to allow for such things as drones and drone taxi services. The Federal Aviation Administration (FAA) mandates that airports provide data in a GIS format to support the satellite-based approach procedures of its NextGen program, an 18-year modernization initiative that began in 2007. Modeling to Guide Maintenance and Operations The added efficiency of Virtual Design and Construction is helping SFO’s infrastructure projects become more streamlined to reduce costs and time to completion. Getting the steps and sequence in the right order in the virtual environment ensures fewer surprises. This animation of the demolition and reconstruction of terminal 1 at SFO shows the value of the dynamic twin to plan, design, and execute a complex construction project with the ability to go backward and forward through time. Some of the work includes a new hotel, modernization of two terminal buildings, a new long-term parking garage, new office building, and the extension of the AirTrain system. The vision to establish a centralized source of infrastructure management information through BIM and GIS provides a contextual awareness that guides SFO’s capital improvements, the largest such program in the US when it launched. SFO began using GIS 15 years ago and implemented BIM five years ago to provide the foundation for its ambitious and transformative $7 billion-plus airport renovations. “We use GIS as the window of entry to all of our infrastructure information,” said Josephine Pofsky, director of Infrastructure Information Management at SFO. At San Francisco International Airport (SFO) all 15 gates on the ‘A’ concourse of the international terminal were closed on April 1, 2020, when international carriers curtailed their routes due to COVID-19 travel restrictions.Īt SFO, improvements are guided by a dynamic spatial environment that combines the detailed building plans and data captured from its owner-driven building information modeling (BIM) processes with the landscape-scale understanding provided by a geographic information system (GIS). ![]() The dramatic decline of air travel during the pandemic gave many airports the opportunity to make progress on construction and renovation projects. Many departments at SFO use the shared model to improve communication and operations.Facility personnel consult the dynamic model to proactively plan complex maintenance operations.Planners at SFO use a dynamic model to find the best place for retail outlets.Doug Yakel, SFO's public information officer, also said that while the structure was made to fit within the terminals, it was also designed to be an "iconic landmark.The infrastructure information management team at San Francisco International Airport has embraced GIS + BIM for improved processes, and fostered a collaborative spirit to add detail to the model while making improvements to facilities. According to Fentress, the "twisting façade" is inspired by the passenger terminal's color, massing, and materials. While the control tower was built to address concerns over its ability to withstand earthquakes, it was also constructed to be eye-catching. In the end, the structure was 220 feet tall, and the 650 square-foot controller section gave air traffic controllers 235-degree views of the airport's runways and taxiways, the FAA explained. ![]() The building was designed by Colorado-based Fentress Architects and Kansas City-based HNTB. Its predecessor was in operation since 1954, but retrofitting the existing building wasn't seen as "feasible," so the airport decided to strip it and construct a new one. The project's main goal was to update the structure to meet current seismic standards, the FAA said.
