Background

With AirSite West, a new quarter with offices, retail, logistics, restaurants and hotels as well as car parks and multi-storey car parks for employees and passengers has been created on an area of 50 hectares at Munich Airport. A newly created traffic junction at the central airport feeder road (junction West zero) and a roundabout on Freisinger Allee at the transition to Nordallee have created optimal connections to the road network. The current use of the site required extensive remodelling and expansion of the original supply and disposal infrastructure. This included the construction of new routes for rainwater and wastewater disposal, telecommunications/electricity supply, drinking and extinguishing water supply, district heating supply and roads for the superordinate development.

Project

The joint venture GAUFF GmbH & Co. Engineering KG and act-consult AG (ARGE development MUC AirSite West) was commissioned by Flughafen München GmbH (FMG) with the general planning of the superordinate development of AirSite West. This included the project planning for the engineering structures (cable conduit systems, drinking and extinguishing water supply, waste water disposal) and traffic systems, the construction logistics planning as well as the coordination of the technical participants for the integration of the accompanying building construction and open space planning. The planning services for rerouting, decommissioning and dismantling of existing routes were also part of the contract.
Based on an existing preliminary design, the execution planning, including the tender documents, was developed from March 2017 on. Construction work for the development measures, which were carried out by Josef Rädlinger Ingenieurbau GmbH, began in June 2018. In total, new water and wastewater pipes with a total length of approx. 4.3 km, medium and low-voltage lines, telecommunications/IT lines with a length of over 12.4 km and a district heating line of approx. 1 km were installed. The roads and walkways for AirSite West consist of around 23,800 m² of asphalt and paved surfaces. The planning was carried out using 3D modelling.

During the execution of the civil engineering work, the partial preservation of existing structures, route coordination, construction water retention and temporary traffic control posed a particular challenge. For example, a temporary road was put into operation specifically for the expansion of Nordallee. During the construction measures for the development, eight building construction projects were realised simultaneously in the neighbouring construction lots. Here, too, the particular requirements of the building structures had to be taken into consideration with regards to infrastructural development. The construction work was carried out while maintaining ongoing operations on the neighbouring roads and ensuring the current supply and disposal for the existing buildings.
