Cost Estimates
Cost estimates are essentials for the processing and control of tunnel projects.
Our step-by-step and independent cost calculation enables our clients to have a detailed overview of the cost-relevant elements and the services to be rendered at any time.
The cost estimates enables our clients cost-wise decisions at any project stage.

Work preparation and installation
Timely work preparation and the project-specific construction site equipements and installations are decisive for the successful and timely execution of every tunnel project.
Our concepts, adapted to all future construction procedures, enable our clients to carry out an installation optimized for all planned construction phases.
The various assembly and disassembly sequences as well as the necessary construction support measures are shown in detail.

Tunnelling is logistic
Logistic is essential for tunnelling for the necessary performance and on schedule. We develop cycle calculations for all individual places of tunnelwork, which are based on the detailed quantity structure per working group.
For this purpose, the mass flows of the supply and disposal per unit of time required for the performance are calculated and the appropriate installations and devices adapted for this purpose are proposed and useful further measures are presented as redundancy in order to minimize possible performance risks and avoid expensive retrofit.

Method of tunnelling and work scheduling
The correct choice of the tunnelling method as well as optimized construction sequences are decisive for the processing of each tunnel project.
We evaluate possible methods of tunnelling as well as work scheduling of each sequence of construction operations of a project and show the belonging performance values, advantages and disadvantages and the risks in variant studies.
For our clients, the achievable performance values are determined based on experiences with the different construction processes, these are shown in construction schedule proposals and the further optimization potential is clearly presented.

Project management
The establishment of a lean, but focused project management is essential for a tunnel construction site.
We support our clients in project management with our structured analyzes and recommendations. Our focus is on the control of interfaces, as well as the timely pursuit and delivery of the open issues for the completion and a comprehensive SET-ACT analysis. With a quality-assured measuring technique and the analysis of the regular examination, a perfect quality of the structure is to be ensured and the corresponding documentation for the client will be created.

Static calculations
Static calculations are required for the steel formwork for the construction of the tunnel lining as well as for the rigid jointed construction of the lattice girder for the reinforcement.
Based on our many years of experience in the execution of inner linings and the production of the steel formworks, we create the necessary static calculations for our clients.
We are specialized in the static calculations of complex geometric shapes and manufacture the correspondingly dimensioned steel formwork and lattice girder for our clients. This is the basis for the execution of a qualitatively perfect inner lining.
