To handle rapid growth in passenger traffic, Rzeszow Jasionka, a communication airport located in the far east of Poland, has been making significant infrastructure investments. Recently, they chose to build new taxiways, complete with a communication network, navigational lighting, and sewer and road drainage facilities. They hired engineering bureau BBKS-Projekt to design the new taxiways and infrastructure network in a way that integrated and coordinated with all prior infrastructure investments, regardless of their phase. All design work had to be completed before winter ended so that the general contractor could construct the assets before severe weather conditions interfered.
BBKS-Projekt used MicroStation’s interoperable environment and advanced referencing to develop a detailed 3D model of rapid-exit taxiways, including intersections with parallel taxiways and existing runways. These skewed, wide intersections required special workflows and unique modeling techniques supported by Bentley Power InRoads. Using standardized procedures and the Power InRoads template library, the team could apply design changes without unnecessary rework. Geographic tools allowed BBKS-Projekt engineers to integrate previous designs based on the old geographic coordinate systems (GCS) into a single and coherent document.
By creating detailed 3D models using Bentley software, BBKS-Projekt was able to deliver high-quality designs that conformed and interoperated with their existing infrastructure investments, on a compressed schedule and avoiding rework. Thanks to MicroStation's interoperability, the design coordinated with all prior investments by the airport – both built and in design – including those designed using old the old GCS.
MicroStation was used to access a public web map server and get detailed information regarding terrain, geology, and local hydrology conditions. For the 3D design, BBKS-Projekt used MicroStation and Power InRoads, which allowed them to combine traditional surveying and laser scanning data as part of the first step to create the digital terrain model, as well as consider many design alternatives simultaneously and select best options for the final design. MicroStation’s Print Organizer allowed them to quickly generate 2D hardcopy drawings for the airport’s officials and the digital designs preferred by the contractor.
