Planning services for the new construction of amphibious structures 01 and 02

Building 01 crosses the future A 14 at construction km 3+681,000 and serves as an amphibious crossing aid. It is to be designed as an integral single-span structure with a clear width of 2.50 m, a usable width of 28.60 m and a crossing angle of 100.00 gon.

Building 02 crosses the future A 14 at construction km 5+895,000 and serves as an amphibian crossing aid. It is to be designed as an integral single-span structure with a clear width of 2.50 m, a usable width of approx. 28.60 m and a crossing angle of 100.00 gon.

The subject of this call for proposals are:

• engineering project planning (services in service phases 1-6),

• structural engineering (services of service phases 2-6) and

The following special/additional services are to be performed:

• Detailed planning of construction phases for special requirements: The planning of the shoring including foundation in the course of work phase 3 is part of the planning.

• Preparation of a risk assessment

• Creation of a construction site plan with representation:

- the excavation pits, obstructions, soil improvements in the backfill area, dam fills, discharge points for dewatering,

- the boundaries of the construction site for the structure,

- the access roads to the construction site,

- Third-party facilities, land acquisition limits, construction roads of the overall measure

• Axes and gradients for the amphibious structures are to be created on the basis of the route planning of the A 14 and the existing terrain in relation to the specified statuses of the structures and the delivery of the data in the formats dxf/dwg as well as the computational axis as data type 040 and the gradient as data type 021.

• Preparation of inventory drawings and inventory overview drawings according to ZTV-ING

• Design according to STANAG 2021 for MLC
