AVA, cost and project controlling


"AVA" as a technical term includes tender, award and invoicing with project cost planning and management

Manage projects with confidence

With RIB iTWO AVA (TAI) software, you completely cover the HOAI service spectrum and confidently manage projects of any size. In building construction and extension, as well as in road construction and civil engineering or TGA. Either classic alphanumeric or model-based according to BIM standards.

RIB offers an integrated process without interface losses: transparent, structured and integrated

  • Audit-proof AVA phase model
  • Individually configurable for roles and workstations
  • Scalable: supports 2D/3D to 5D BIM working methods
  • Open architecture: easy integration into your IT environment from CAD to SAP
  • Cross-national standard-compliant working
  • Traditionally powerful: project and detail analyses according to DIN 276, AKVS, building structures, building sections, cost units, trades, RBBau
  • Latest exchange formats: GAEB, ÖNorm, CH-Norm, IFC, CPIXML, BCF

Costs, tendering, controlling: integrated is simply safer

Tender software that gives you the security that is indispensable for qualified HOAI services: Legally through the audit-proof traceability of different development statuses. Functionally through traceable work steps, consistent data structures (master data), internal check functions and standard-compliant interfaces.


Project phases and workflow concept: A transparent and verifiable data basis at all times with less effort.


Refined to perfection: Easy to use like a Microsoft Office product, customizable for each workstation.


Integration: Ideally combined with CAD, ERP, procurement or FM systems in many system environments.

Hand in Hand: AVA und BIM

AVA integration of BIM building models

Building Information Modeling (BIM) is increasingly required for project tenders in civil engineering and road construction. RIB supports BIM with a particularly comprehensive BIM 5D approach.

This integrates not only 3D CAD model data but also all service descriptions, costs, schedule and process components required for further construction as the 4th or 5th planning dimension. As a "digital process twin" for your further project planning, this BIM 5D model offers potentially a

  • more efficient model-based cost control and forecasting
  • better planning of construction times and maintenance intervals and a
  • higher transparency of construction risks and costs.

BIM made simple

For us, BIM 5D means the future of planning for many project types. Standardized, standards-compliant information on construction costs, construction services and attributes for linking to your BIM model provides a quick and safe introduction to BIM. This new technology simplifies data exchange between CAD and AVA.
