Design of Priority Improvement Works at Gautam Buddha Airport

  • Gautam Buddha Airport at Bhairahawa is an important hub airport in the Western Development Region of Nepal. The airport has a paved runway (1500x30 m), a taxiway (95x15 m) and an apron (92x62 m) constructed in 1970s. The landside area is about 450x200 m. Because of proximity to Lumbini, the birth place of Lord Buddha, the airport offers high potential to tourism. Hence, CAAN has conceived a plan to update this airport to a regional international airport to be able to operate medium sized jet aircrafts such as Boeing 737. GEOCE carried out the following scope of services for this project:
  • Topography survey of runway expansion (1388x200m) and Ghaghar Khola diversion

Commercial Viability Study of Land Use at Tribhuvan International Airport

Tribhuvan International Airport (TIA) Master Plan includes a Land Use and Zoning Plan showing allocation and protection of land use both on and off the airport within the airport boundary to support phase wise improvements of TIA to 2015. The Land Use and Zoning Plan has identified and designated different locations in TIA area for various purposes required to fulfill the demands of an international airport. However the plan has not considered certain locations of TIA for the construction and expansion of infrastructures. These locations could be utilized for various commercial activities such as hotels, shopping mall, airline and cargo complexes, airport catering, restaurants and fast food centers, recreation ground, golf course and others. TIA could lease out these lands to prospective developers, airlines and cargo operators and others to develop and operate such commercial activities, which will generate additional revenues to CAAN. GEOCE carried out the study for viability assessment for commercialization of above land at Tribhuvan International Airport in Kathmandu.
