Negotiated award with public competition (service) Former Erlensee Air Base, Phase IIa according to Bfr Bogws and Phase C according to Bfr Kmr Explosive ordnance clearance planning and construction monitoring; environmental investigations; The former US property "Erlensee Air Base Kaserne" is owned by the Federal Republic of Germany and lies approx. five km northeast of the city of Hanau in the Main-Kinzig district, Hesse. The air base was built between 1936 and 1939 by the German Air Force and various fighter squadrons, reconnaissance troops and a gliding school were stationed there until 1945. During the Second World War the site was used by at least... Affected by six air raids (bombing with suspected long-term fuse ammunition) and badly damaged by artillery fire. After being captured by the Allies on March 29, 1945, the air base was subsequently used by US forces. The total area of the economic unit (WE) is approximately 1,670,000 m2. Renaturation measures have already taken place on parts of the WE, and other areas are to be reforested and will serve as compensation areas. The contractor (an) is responsible for carrying out Phase IIa (orientational investigation) in accordance with the building regulations for soil and groundwater protection (BFR BOGS) with a particular focus on suspected munitions (high-explosive bombs, some with long-term fuse ammunition) on the property. To ensure occupational safety, explosive ordnance clearance must be carried out on an area of approximately 3.5 hectares in accordance with the technical construction guidelines for explosive ordnance clearance (bfr Kmr), and the inspection of around 50 suspected unexploded ordnance points (bvp) must be planned and implemented by the AN. On the basis of the results of earlier research and environmental studies, an investigation concept for currently 15 areas suspected of contamination (kvf) was developed, which is to be optimized by the AN and, in particular, to be supplemented to include the PFAs pollutant group. The aim of Phase Iia is to examine the suspected contamination and make a qualitative assessment of the need for further measures. The results are to be documented in detail and recorded in a specialist information system Insa. The AN is also responsible for planning, accompanying and monitoring the project, including supporting the award procedure and construction supervision for explosive ordnance clearance as well as expert monitoring and safety coordination. Furthermore, nature conservation concerns and the breeding and nesting season must be taken into account in planning and implementation.
