In 1997, the airport started the process to install a doppler very high frequency omnidirectional range (DVOR) to aid navigation, which would cost NOK 800,000 used, plus NOK 400,000 for installation and construction of a road. The DVOR was operational from October 1998. The Norwegian Labour Inspection Authority instructed the airport company to improve the facilities for both employees and passengers, and in February 1997, the airport company decided to build a new passenger terminal and a new operations building for a combined cost of NOK 12 million. The new passenger terminal would be in two stories, with the tower in four. Instead the airport chose a larger proposal, also designed by Svein Halleraker, which cost NOK 25 million.
