The core scope of work and statement of work summary for this tender, based on the provided documents, encompasses several distinct areas:

1. Cable Infrastructure and Road Construction on BAB 40: This scope involves the new construction of a cable protection pipe system in open construction, the delivery and installation of approximately 50 cable shafts of various sizes, and the supply and laying of about 12 km of copper tracer wire. It also includes copper cable assembly, testing and acceptance measurements, existing condition surveys, and documentation (creation of existing plans). Further, it covers the creation of construction and assembly planning, civil engineering preparation for telematic detection at interchanges with carriageway crossings, and the pulling in and connection of 6DA copper cable into the protection system. Road construction elements include the creation and potential dismantling of temporary median crossovers for traffic management, as well as the upgrade of permanent median crossovers with new vehicle restraint systems. Additionally, the work includes the reconstruction and new construction of paving on bridge superstructures (including sealing), FRS systems on head beams, and railings on head beams, along with reinforcement location measurements. Telematics systems and fiber optic work are explicitly excluded from this scope.

2. Noise Barrier Construction and Telematic System Preparation on BAB A57: This scope includes the dismantling and new construction of noise barriers (LSW 1 and LSW 2). The work involves creating execution static analysis and planning, earthworks (excavation, backfilling, gravel covering), pile foundations using steel ramming pipes, and the creation of concrete socket formations. It also covers the installation of structural steel wall posts, reinforced concrete socket elements with drainage, one-sided highly absorbent aluminum noise protection cassettes, service doors, post caps, and stair systems with angled retaining walls and steel tube railings. Technical processing, boreholes for unexploded ordnance detection (including contact boreholes), and the creation of drainage channels are also part of this. Furthermore, this scope entails surveying non-specified lines, creating execution documents and site protocols, setting up and operating a central unit for automatic system management, and configuring three web-based observer accesses for the client. Traffic safety measures for the system setup and clearing of planned stand areas (including bushes, trees, and rootstock) are also required. It also includes the installation of external components (MQ and AQ units) for loop current detection systems (SWA) at specified locations on the BAB A57 for detection tasks.

3. Supplementary Claim Processing (Nachtragsbearbeitung) for Major Projects: This service focuses on the examination and processing of supplementary claims arising from construction and maintenance contracts in road construction and structural engineering. Key tasks include reviewing and negotiating supplementary offers, preparing supplementary agreements (according to the Autobahn GmbH form), creating supplementary service specifications with clear and exhaustive descriptions, and developing meaningful justification notes. The scope also accounts for all costs associated with preparation, expenses, travel, personnel, and accommodation for meeting appointments, alongside the creation of meeting protocols. This service is initially confined to two specific major projects, with a possibility of expansion to other major projects in the NL Rheinland area based on workload.
