Germany's Hamburg Airport has unveiled plans to invest €120m for the renewal of the main apron for enhanced operations.
The renewal project will see Apron 1, with a total surface area of 330,000m² undergoing upgrade in nearly ten phases within four years.
The project has been extended to reduce impact on scheduled flight operations for passengers.
Hamburg Airport CEO Michael Eggenschwiler said: "We see the comprehensive apron refurbishment is an investment for the future. Aircraft will be able to taxi and manoeuvre better and more quietly on the new surface. This will result in reduced noise and exhaust emissions, an important goal along the path to sustainable airport infrastructure.
"Carrying out the construction work over several years during ongoing operations is a great challenge for our entire team. But with this approach we are keeping the impact on flight operations as small as possible."
The project, which is intended to offer a new life cycle of approximately 25 years, will include renewal of all pipes, cables, technical equipment, the concrete surfaces, including taxiways and aircraft parking positions.
Additionally, it will include deeper underground facilities such as storm water channels for which the target utilisation period is estimated to be 50 years.
The first phase of the project includes work on 59,000m² in the southern apron and terminal area and is expected to commence in March 2016.
The authorities have awarded contracts worth €40m for the currently planned first five phases.
A consortium consisting of Bickhardt Bau and Krebs Infrastruktur & Betonbau has been selected to carry out the initial phases.
The contracts for Phases 6-10 will be awarded following a tender process that will take place at a later date.
Hamburg Airport has been upgrading its facilities such as the new Air Cargo Center that features modern freight handling processes.
The new facility which started operations earlier this year replaced the previous air cargo centre, while retaining a total space of 60,000m².
