Follow-up order for Terminal 3

After CANZLER was entrusted with the planning of the building management system (MSR) for Terminal 3 in 2013, Fraport AG has now also placed an order for a concept for the HVAC and sanitary technology. The planning focuses on highly flexible future use of the spaces.

The new terminal will enter the market in the first expansion stage in 2023. At this point, it will offer capacities for 14 million travelers annually across a surface area of 90,000 square meters, whereby the total surface area comprises 306,000 square meters, which extend across five upper and two basement floors. Wide-body aircraft from across the globe will soon be docking at the 24 gate positions. According to calculations, total costs will amount to between EUR 2.5-3 billion.

CANZLER is responsible for planning the maintenance groups heating, cooling, ventilation and sanitary systems and will furthermore support Fraport in the tendering process. The Canzler engineers are currently working on the itemization of the design planning, which is anticipated to be completed in mid-2017.

All kinds of usage, many requirements

“It is not only the sheer dimensions that make this large-scale project highly complex, but the many different types of usage,” explains Jens Kuhnert, responsible project manager at CANZLER. Alongside passenger areas, offices, retail and catering, there are also special areas such as those for the federal police force and customs office. “The diverse uses result in a great range of requirements,” says Kuhnert. While in the retail areas elevated cooling capabilities, or in the catering sections grease traps and kitchen exhaust air systems must be factored in, the facilities for the passenger areas must be conceived in such a way that comfortable ambient conditions are ensured regardless of changes in the external climate or widely varying passenger numbers. Further factors are safety-related systems for fire protection, such as for example smoke extraction and pressure ventilation systems. “The contractor wants to realize an energy-efficient and sustainable property, which is why for example the exhaust heat of the baggage handling system is used for heating the terminal,” Kuhnert explains. Before the terminal is completed, around 160 km of supply lines and about 120 km of ventilation ducts or lines will need to be installed. Ventilation systems with an overall supply air volume flow of about 1,200,000 m³/h are foreseen. These numbers alone attest to the gigantic scope of the construction project.

Flexible planning for operations

A further challenge lies in carrying out the planning in such a way that at the moment of inauguration, systems employing the latest available technology are in use. “At the same time we need to plan the systems flexibly, in order to make different usages possible,” Kuhnert relates. All of this requires future-oriented planning with the highest requirements to the flexible usage of the terminal’s spaces. CANZLER not only has the know-how needed for such large-scale projects, but also possesses experience when it comes to different requirements for use in passenger terminals.

CANZLER has been active for Frankfurt Airport for over ten years. During this time, out specialists have been handling projects related to all HVCSE technologies at Terminal 1 in order to adapt the building to changed requirements.
