BIM – Bidding Process

Faster and more accurate bidding through Building Information Modelling

We have recently reported on the BIM area "Modelling and Design", in which 3D models are filled with all project relevant information. These models are an important basis for the next BIM area that we will present to you: The bidding process for possible contract work.

The models are an important pillar for the project screening. Since in future our BIM databases will contain all relevant information on quantities, costs and construction progress, the screening of project tenders will make it possible to identify the opportunities and risks associated with the project at an early stage and with little effort, and determine the prospects for profit. This significantly reduces the effort required to search for project opportunities on the bidding platforms through a "Bid Management Collaboration Tool", standardises the evaluation criteria for attractive projects and makes is possible to concentrate on projects with the highest profit prospects.

Once 3D models are available in the bidding process, we are able to automatically determine the exact quantities, detect errors in the tender and visualise the planned construction processes. This significantly increases the quality of the tender. In future it will also be possible to plan time and costs in/on the model.


BIM enables the calculation for the project with models, so you are no longer dependent on the experience of the individual cost estimator, but can draw on the wealth of experience of the entire organisation. This creates many advantages:

  • Time saving: material and personnel requirements are automatically calculated.
  •  An overview of required quantities can be generated quickly, this also allows a plausibility check.
  • Better estimate of quantities and costs.
  • Changes in customer requirements can be incorporated into the quotation more quickly. If the model changes, the quantities change automatically.
  • A model-based calculation enables transparency in the quotation process.
  • Tendering costs are significantly reduced.

Pilot project “Koralmtunnel”

We are currently testing this form of bid processing in our tender for the ÖBB "Koralmtunnel" project. The length of the planned tunnel is 32.9 kilometres and therefore requires an innovative approach to determine the use of materials and personnel. Extraction and provision of information is enabled through working with various databases:

  • Bently Advancing Infrastructure
  • Synchro Software
  • Autodesk
  • RIB
