The A 1 is on Niedersächsischem area over a length of 29.4 km zw. The AS Lohne / Dinklage and the AS Bramsche 6-strip expanded. The expansion takes place as a functional construction contract (FBV). As part of the implementation of the FBV, the contractor of the FBV (AN-FBV) provides planning, construction and maintenance services over a period of 30 years on a fixed section of the route. During the construction phase, disposal work must be carried out in relation to a tar sand layer underlying the old concrete carriageway. The overall performance of the FBV comprises in detail the six-lane expansion while maintaining the traffic, the construction of engineering structures, systems of road drainage and noise protection, the street equipment, proportional landscaping measures and the maintenance of the contract section. Furthermore, the service includes the repair of existing overpass structures, which, however, do not pass into maintenance of the AN-FBV after repair.

The regional business unit Osnabrück of the NLStBV will use 2 independent administrative assistants, the Upper Construction Authority (OBB) and the Interdisciplinary Construction Management (IBB) for the operative contract management and supervision. Subject of this award is the IBB. The OBB is advertised in a separate procedure. Together OBB and IBB form organisationally the place, which accompanies and supervises the contract execution on the spot. They check and document all influencing factors relevant to the contract and the billing, such as performance target, availability restrictions. IBB is technically subordinate to the OBB subject. The client expects IBB to always have up-to-date knowledge of the progress and the quality of the on-site contract execution. The functional construction contract requires support, monitoring and contract management that deviates from the conventional procedure and is project-specific. The IBB has to contribute to the required level of technical meetings in coordination with the OBB. The IBB supervises, whether the execution of services and supplies for the fulfillment of the functional construction contract over the 6 strassenigen development and the preservation of the A1 in the fields of road construction, constructive civil engineering, landscaping and environment as well as waste / disposal using the functional rules and regulations introduced by the AN-FBV be fulfilled in accordance with the contract. The interdisciplinary service provision is to be controlled, coordinated and brought together internally within IBB. In addition, she is involved in monitoring conservation and operation.
