Rome Fiumicino Replacement of Boarding Bridges

Leonardo da Vinci International Airport is the Rome’s main airport. 37 million passengers annually pass through its terminals making the busiest airport of Italy. Currently the airport is severely over utilizing the original design capacity. While there are plans in the making for a significant expansion to the north, the existing south terminal is continuously being improved. Hence the replacement of 31 boarding bridges to allow the latest aircraft to be served. The boarding bridges shall all be delivered by a single supplier and therefore a tender will be issued by Aeroporti di Roma, the airport’s operator. Deerns was requested to prepare the performance criteria and program of requirements for the bid documentation. In addition Deerns was requested to review the stands on functionality, usability for future aircraft and the new demands of the airport.

Deerns' scope of services

To be able to tender the project, Deerns has been requested to prepare the functional and technical programs of requirements, for both the pedestal bridges and the apron drive bridges. In addition to the tender documentation, ADR has requested Deerns to analyse the aprons for the use of future aircraft. ADR is planning to utilize some of the gates at the D concourse for larger aircraft in the near future. Deerns will indicate the consequences of the adjustments in gate use, not only for the passenger boarding bridges, but also for taxiways and apron services. After selection of the bridge supplier had taken place, Deerns has taken care of the design approvals, the factory acceptance tests and site acceptance tests.


To have insight in the existing passenger boarding bridges and their functionality, simulations of the gates were made. There was room to optimize the positioning of the bridges. The simulations indicated that for a couple of gates, the length of the bridges may be changed to have a better working range, more flexibility, a safer parking position or applicability prepared for future fleet mix.

Future gate changes

Given the broad expertise shown by Deerns ADR came about with more requests. What would it take for two C-type gates with pedestal bridges to receive E-type aircraft in the future? Effectively creating a MARS stand. Is it also possible to handle longer aircraft on a smaller apron at the D concourse? Deerns re-designed the aprons, which need to be longer, developed new schematics for the taxiways and service roads. All shall be altered and some new restrictions will be introduced. Deerns created the drawings for the spatial needs of the aprons in the future situation, which ADR has integrated in the new airside design around the D-gate.
