Estimating under time pressure
Bills of quantities with hundreds of items have to be priced in a few days — often alongside running projects.

AI in Construction
Hardly any industry works with as many documents as construction: bills of quantities, plans, site diaries, change orders, defect notices. Artificial intelligence (AI) can carry exactly this paperwork — and gives site management and estimating time for what brings margin.
At the same time, documentation decides money on site: whoever records site conditions, disruptions and defects completely enforces change orders and fends off claims. AI makes this documentation a side task — via photo and voice note straight from the site.
We know the system landscape in construction — from tendering software to site-diary apps — and integrate AI where it pays. GDPR-compliant, with funded training for site management and estimating.
challenges
Where the industry gets stuck
Change orders fail on documentation
Disruptions and extra work are settled verbally and never recorded — in the end, the evidence is missing.
Defect management eats time
Recording, assigning, tracking and documenting defects across trades and firms is a full-time job.
Poorly scheduled material and equipment
Missing material stops crews; equipment sits on the wrong site.
use cases
Concrete AI use cases
Six entry points proven in practice — each connected to your existing systems and data.
BoQ analysis and estimating assistant
AI reads bills of quantities, flags items with risk and proposes prices from your past estimates.
Digital site diary by voice
Dictated entries and photos automatically become VOB-compliant daily site reports — searchable and evidence-proof.
Defect capture with photo AI
Take a photo, let the defect be described, assign the trade, set a deadline — follow-up runs automatically.
Change order management
AI detects change-order-relevant events in correspondence and site diary and compiles the documentation for them.
Material scheduling
Requirements from schedule and BoQ automatically become order proposals — aligned with the site's delivery dates.
Plan and document checking
New plan revisions are automatically compared with old ones; changes and clashes are flagged before they show up on site.
services
How we support you
Process Analysis
We scrutinise estimating, site management and invoicing and find the biggest time sinks.
AI Integration
Connection to tendering, ERP and site apps — solutions that also work on a tablet with gloves on.
AI Training
Site managers, foremen and estimators learn to use AI on real project examples — state-funded.
Use funding
Construction companies in Saxony can have planning, software introduction and training of a digitalisation project funded via the SAB digitalisation grant — from a project volume of €5,000. Nationwide, the Qualifizierungschancengesetz funds further training for your employees with up to 100% of course costs — Sellium is an AZAV-certified training provider.
faq
Frequently asked questions
Where does a construction company best start with AI?
With documents: site diary, defect capture or BoQ analysis. These use cases need no new hardware, run on existing tablets and show results quickly.
Does AI really help with change orders?
It does not replace a construction lawyer, but it provides what change orders usually fail on: complete, dated documentation. AI detects change-order-relevant events and compiles evidence.
Does it work on site without a stable network?
Yes — capture via photo and voice works offline and syncs as soon as a connection exists. We take this into account when selecting tools.
What about our project and customer data?
It is processed in compliance with GDPR, fully on your own infrastructure if desired. We regulate access by project and role.
Is there funding for digitalisation in construction?
Yes. In Saxony the SAB funds digitalisation projects of construction SMEs including training; further training of site management runs nationwide via the Qualifizierungschancengesetz. Details on our funding page.
