Caterpillar smoothens Colombian airport

August 21, 2013

Cartagena, Colombia’s coastal city attracts large numbers of visitors, generating heavy traffic through the Rafael Nuñez International Airport. However the surface of the runway had suffered from heavy wear, r esulting in bumpy landings and this was in need of repair. In addition, engineers wanted to create a graded, ramped approach to aid with both take-offs and landings. However, the volume of air traffic using the airport meant that construction work had to take place in a tight timeframe, between mi

Redevelopments at southern Polish airports

August 21, 2013

Rzeszów-Jasionka Airport in the south-east of Poland is now benefiting from a new taxiway constructed over a 50-month period and costing some €22.5 million. The work was required as the airport needs to increase capacity to cope with growing passenger traffic. The main portion of the project was for the construction of a 3km long taxiway, which lies parallel to the airport’s main runway. This taxiway now allows aircraft to manoeuvre away from the single runway and free up capacity for take-offs and land
