First Class electrical planning

25Apr

Frankfurt Airport, Germany's largest international airport and Lufthansa's global hub, is expanding with the assistance of WSCAD's E-CAD software platform. Fraport Aufbau Süd GmbH, responsible for planning the new Terminal 3 including its building automation system, selected the WSCAD SUITE for its speed and flexibility in implementing 150,000 automation functions across the entire 403,000m² structure.

Frankfurt Airport's new Terminal 3, expected to go into operation in 2026, will eventually comprise five upper and two lower floors, hosting 25 million additional travellers each year. Planning the building automation, air conditioning, heating and ventilation is a vital requirement, managed by CANZLER GmbH on behalf of Fraport.

Specifically, retail spaces need sufficient cooling capacity to deal with fluctuating passenger numbers, regardless of external climatic conditions. Fraport also required environmental sustainability features such as recycling waste heat from the baggage handling system to heat the terminal.

With function lists according to the German standard VDI 3814, creating a unified basis to simplify planning, management and operation, and features to speed up the design process while maintaining accuracy, Fraport selected the WSCAD SUITE with its Building Automation module. The E-CAD software was also adopted by CANZLER.

"To avoid data errors and time delays, we paid special attention to the consistent planning of the building and room automation from the beginning," says Uwe Eckardt, Planning Coordinator for Building Automation, Fraport Aufbau Süd GmbH. "BACnet object-related function lists according to VDI 3814 can be implemented perfectly with WSCAD and it was the only system with the performance features required by Fraport."

CANZLER planned the building automation system for the terminal that involved the regulation of heating, air conditioning and cooling systems as well as the monitoring of sanitary and sprinkler systems. In total, this included approximately 1,500 rooms and the smoke control of the entire terminal. With 240 controls and components, the system comprises around 90,000 data points and 150,000 automation functions, all of which have been designed and placed with WSCAD.

A key feature of WSCAD's E-CAD software is the item referencing that enabled the entire air conditioning system to be designed in accordance with IEC 81346. Systematic structuring from the outset significantly accelerated and simplified the planning as well as development process. WSCAD enabled the scalability to duplicate then customise areas of design according to location and required function.

For example, the drive of a ventilation system including motor, protection and control can be quickly replicated for use in the same form in another building area by drag and drop of the desired macro.

To ensure accurate and rapid referencing of duplicated areas, all stored labels are automatically inserted into the new structure. This also means that correctly structured, error-free cable or parameter lists for individual system parts can be generated very easily when required. With around 200 ventilation systems involved in the Terminal 3 design, this was a significant advantage in time saving.

"When planning building automation projects, the automatic generation of data point keys as well as the ability to change them quickly and easily afterwards is very important," says Heike Frommhold, CANZLER GmbH.

The system key developed for the project, including user address and data point, consists of a total of 31 digits. The automated creation of data point keys is also possible with WSCAD for projects using existing keys. When changes are made, the software automatically updates the system key across all data points. The plug-ins for building automation-specific data point keys supplied with WSCAD's software, as well as the extensive symbol library with article data, also increased the speed of design with no need for manual or bespoke generation.

Fraport and CANZLER also benefitted from WSCAD's database that enables simple export of all project data, and project-specific article databases can be easily created to bespoke standards and formats. For both design and data management, CANZLER found the software intuitive to use from the start. The next step in the development of Frankfurt's Terminal 3 is to implement the building automation itself.

"Airports are complex and technically sophisticated buildings that require a special planning," says Uwe Eckhardt, "and thanks to WSCAD we are on track to deliver the project to schedule."
