SIDOUN International GmbH

SIDOUN International GmbH – AVA and Construction Costing Software for Modern Construction Processes

SIDOUN International GmbH has been developing AVA and construction costing software for the construction and planning industry for almost 50 years. The owner-managed software company combines long-standing experience with the continuous development of digital working methods.

The aim of SIDOUN’s software solutions is to create flexible processes, noticeable time savings and more room for planning and professional decision-making. SIDOUN develops tools that reduce routine work, make project knowledge usable and support users across different phases of a construction project.

The portfolio ranges from classic AVA software to solutions with AI support directly within the project context. Users include architects, engineers, construction companies, construction groups, project managers, public-sector clients and municipalities.

AVA and Construction Costing Across the Entire Project Process

SIDOUN software supports key tasks in tendering, awarding and billing as well as cost planning, cost determination and construction costing.

This includes, among other things:

• cost planning and cost determination in accordance with DIN 276
• creation and processing of bills of quantities
• GAEB-compliant data exchange
• bid evaluation and awarding
• construction billing and change order management
• construction costing and ongoing costing
• cost control and evaluations

Flexible working methods play an important role. Users can structure project information, connect different areas of work and continue using existing data.

KIAVA® – AVA Software with AI Support

With KIAVA®, SIDOUN combines classic AVA and construction costing with AI support directly within the project context. AI assistants support users with questions, the creation and review of bills of quantities, semantic search and the use of project and knowledge data.

AI support does not replace professional decision-making. It reduces routine work, prepares information and assists users wherever searching, checking or recurring tasks consume valuable project time.

This creates more room for planning, control and professional decisions.

Additional KIAVA® functions include:

• Excel-Inside for working directly with tables, calculations and costing models
• Word integration
• Team Mode for parallel work on a shared project
• selective undo function
• multi-window working
• GAEB and BIM support
• project-related knowledge and search functions

Classic AVA Software for Established Workflows

With SIDOUN Globe®, SIDOUN continues to offer classic AVA software for cost planning, tendering, awarding and construction billing. It supports users in the structured processing of construction projects and combines established AVA functions with flexible working methods.

Globe4all also provides a free entry point into professional AVA processes.

SIDOUN therefore covers different requirements, ranging from classic AVA work to workflows with AI support.

For Architects, Engineers, Construction Companies and Public-Sector Clients

SIDOUN software solutions are used wherever construction projects are planned, tendered, costed, awarded and billed.

Typical users include:

• architectural practices
• engineering firms
• construction companies and construction groups
• project managers
• public-sector clients and municipalities
• companies from industry and infrastructure

The size of the organisation plays a secondary role. SIDOUN supports both smaller planning offices and larger companies and public-sector organisations in the structured and efficient processing of demanding construction projects.

Open Standards and Flexible Collaboration

SIDOUN supports established standards and interfaces for the exchange of project and cost data. These include:

• DIN 276 for cost planning and cost determination
• GAEB for the exchange of tender and bid data
• BIM-based workflows
• Excel and Word integration
• flexible data and project structures

Existing working methods can therefore continue to be used and connected with digital processes.

Almost 50 Years of Experience – with a Clear View Ahead

SIDOUN was founded in 1977 and has continuously developed its software in line with the requirements of construction practice ever since. The owner-managed company based in Freiburg combines long-standing AVA expertise with new technologies and flexible working methods.

SIDOUN develops technology with one clear goal: less routine work, faster access to relevant information and more time for planning, professional decisions and the actual project work.

SIDOUN develops AVA and construction costing software for the professional planning and management of construction projects. The portfolio ranges from classic AVA solutions to software with AI support directly within the project context. The aim is to create flexible workflows, reduce routine work and give users more time for planning and professional decision-making.
