Overall measure, lot 1-4:
The measure includes the thorough repair of the BAB A3 between AS Lohmar u. AK Bonn / Siegburg including the renewal of the complete bonded superstructure, roof renovation of the AS-Lohmar, renewal: drainage, groundbreaking signposting. StVO signage, demolition of 13VZB / VZT, reorganization of 17 VZB / VZT, replacement of 7 buildings, renovation of 6 structures and renewal of 5,083 m noise protection systems (all lot 1, EU). It also includes the transport time schedule (Lot 2, EU), the Vehicle Restoration System Renewal, FRS (lot 1/3, EU), equipment, traffic clearance and permanent registration (lot 4, DE).
It is to ensure the maintenance of traffic with a 4 + 2 traffic guidance.
It is built in 4 main construction phases with preparatory u. downstream phase.
For d. Traffic safety work is based on type 4.
Total construction time Stage 0-5: 873 business days
The building description is valid f. all 4 lots
Vehicle restraint systems (steel), lot 3:
Vehicle restraint systems on the edge of the road Construction process Protective device. The construction process safety guard is bound to the course of the construction of the course. For the installation of the protective devices of the present lot, the above-mentioned traffic management phases are authoritative. Furthermore, it can be assumed in the sub-phases that the installation can not take place in one go (no line construction site). A repeated approach to the construction site in many sections over the entire construction period is
To be included. In connection with the construction work in the course of the actual and subsequent construction of the line (see above), the performance of the demolition of existing safety equipment must be observed. With regard to the construction process, it is explicitly pointed out that the present road construction measure is carried out in many sub-phases. The number of partial phases depends ultimately on the construction process of the AN track construction lot 1, which is only available at the beginning of construction and can undergo changes and adjustments in the construction progress Dismantling existing vehicle restraint systems in the shoulder. The stock mainly consists of protective equipment made of steel. In the median strip, these are double distance protection planks and two-strand distance protection planks in the area of bridge structures and installations. At the outer edge are distance protection planks and simple crash barriers. At some locations of traffic sign bridges concrete protection walls have been installed. Basically, all existing protective devices are replaced.
The dismantling of all safety devices is not part of the present scope of performance and is realized by the AN "Fachlos Guards Stahl" lot 3 (including median strip). Likewise, by this AN the installation of the protective device is carried out on the roadside.
It should be noted that the dismantling and installation of the protective devices must be carried out in the course of road construction, this within the individual subphases / traffic management phases
or in preparatory phases with separate traffic management. In the course of the individual subphases / traffic management phases, these works are still to be carried out in several subsections. This circumstance must be taken into account in the calculation.
The necessary close coordination and coordination between the track construction and other trades must be taken into account and included in the corresponding positions.
Bridge structures:
On bridges that use roads, paths, tracks and waterways as part of the highway, steel barriers with retention level H2 or H4b are to be installed.
With the dismantling of the existing crash barriers by the contractor "Fachlos Schutzseinrichtungen aus Stahl" Lot 3, the original anchorages on the caps are also dismantled at the same time.
On structures, the corresponding dilatation elements of the protective device must be provided.
Rough mass determination, subject lot 3
dismantling
