From days to hours
How artificial intelligence creates service specifications, optimises tenders and minimises project risks
The creation of service specifications is one of the most time-consuming and error-prone tasks in project management. Hundreds of items must be described in detail, quantities determined, standards referenced and interface issues taken into account. A single forgotten item or an imprecise service description can later lead to addenda, disputes and cost explosions. At the same time, manual service specification creation ties up valuable capacity that is then lacking for strategic project management. AI-supported systems are revolutionising this process. They analyse BIM models, automatically generate service specifications and optimise tenders faster, more accurately and with significantly less risk.
From BIM to LV: automated quantity determination
Modern BIM models contain all the geometric and semantic information about a building. AI systems automatically extract quantities for tenders from this information: square metres of plastered surfaces, cubic metres of concrete, metres of pipe lengths, precisely calculated from the 3D model. What employees used to spend days calculating manually, AI now delivers in minutes.
The technology goes beyond simple area calculations. Machine learning algorithms recognise component types, automatically assign them to STLB-Bau positions and take into account surcharges for waste, degrees of difficulty or special execution conditions. A window is not only recognised as a geometric object, but also includes the installation situation, insulation value requirements and necessary ancillary services such as window sills or seals.
Intelligent text generation: From standard texts to project-specific descriptions
The biggest challenge in creating bills of quantities is not the quantity figures, but rather the precise service descriptions. AI systems draw on extensive databases of standard service texts, STLB-Bau, VOB-compliant formulations, manufacturer-neutral product descriptions, and intelligently adapt these to project-specific requirements.
Natural language processing (NLP) makes it possible to automatically generate service texts from planning documents, building descriptions, and technical specifications. The AI understands contexts, recognises dependencies between trades, and formulates complete, comprehensible service items. Where copy-paste with manual adjustment used to dominate, consistent, consistent texts are now created in a matter of seconds.
Error reduction through plausibility checks
Human errors in service specifications are costly. Forgotten items lead to addenda, duplicate tenders lead to confusion, and contradictory information leads to legal disputes. AI systems perform automated plausibility checks:
- Have all components from the BIM model been taken into account?
- Do the quantities match the building geometry?
- Are there overlaps between items from different trades?
- Are all necessary ancillary services included?
- Do the formulations comply with VOB requirements?
These checks run parallel to the creation of the bill of quantities and provide early warning of inconsistencies. What would only be noticed during manual work when evaluating bids or during execution is already corrected in the planning phase.
Historical data analysis: learning from past projects
AI systems become more intelligent with every project. They analyse completed tenders, compare bid results with cost calculations and identify patterns. Which items frequently led to addenda? Where were bids systematically above or below calculations? Which formulations led to queries?
These predictive analytics are incorporated into new tender specifications. The AI suggests more precise wording, warns of historically problematic items and recommends levels of detail that have proven successful. This creates a continuous improvement process that systematically reduces project risks.
Dynamic tender optimisation
AI not only supports the creation of tender documents, but also the tender strategy:
- Bidder allocation: Algorithms analyse bidder profiles and recommend which companies are best suited for which positions based on specialisation, regional presence, previous bid prices and project experience.
- Lot formation: How should trades be bundled to obtain optimal bids? AI simulates various lot scenarios and forecasts price effects.
- Scheduling: When should which trades be put out to tender in order to make optimal use of market prices and avoid delivery bottlenecks?
Automate bid evaluation
Bids received are automatically analysed by AI systems:
- Price comparisons: Which items deviate significantly from the average?
- Completeness check: Has all the required documentation been submitted?
- Form check: Have the tenders been filled out correctly?
- Reference check: Are the prices in line with market levels and historical data?
Any anomalies are automatically flagged and test reports are generated. What used to take days, AI can now do in hours – without overlooking any details.
Integration into existing workflows
Seamless integration into existing systems is crucial for practical use. Modern AI solutions work with common BIM platforms (Revit, ArchiCAD, Allplan), AVA software (ORCA, iTWO, RIB) and ERP systems.
Together with B3YOND-IT, 3XPERTS develops customised interfaces that integrate AI functions directly into your working environment. Whether as a cloud service, local installation or hybrid solution, the technology adapts to your processes, not the other way around.
Time savings and cost reduction
The efficiency gains are measurable:
- 80 % time savings in quantity determination through BIM automation
- 60 % faster specification creation through intelligent text generation
- 40 % fewer addenda through more complete, more precise tenders
- 25 % reduction in tendering costs through automation
These figures are based on real project experience and show that AI is not a vision of the future, but a practical tool with immediate added value.
Data security and confidentiality
Tender data is highly sensitive. AI systems must meet the highest security standards:
- Encrypted data processing on-premises or in certified data centres
- Access controls with role-based permissions
- Audit trails for complete traceability
- GDPR compliance when processing personal data
B3YOND-IT implements security architectures that ensure both efficiency and data protection.
Limitations and human expertise
AI does not replace the expertise of experienced project managers; it enhances it. Complex special items, project-specific features or legal subtleties require human judgement. The role shifts from operational creation to strategic review and optimisation.
Successful AI integration means that machines take over repetitive, rule-based tasks, while humans focus on exceptions, innovation and relationship management.
