Control quantity measurement for every role in the project
When quantities, evidence and decisions live in spreadsheets and email, commercial control becomes reactive. CASAI connects the chain in one traceable workflow so clients, contractors, project teams and executives see the same status in time.
Same symptoms, different consequences by role
Versions instead of a chain
Submissions, calculations and comments live in parallel files. It becomes unclear what is current and what is already approved.
Review that takes too long
When evidence is missing or hard to find, lead times, open items and friction between parties grow.
Commercials rebuilt after the fact
Forecasts, payment support and portfolio views become manual consolidations instead of a sequence of decisions.
Hard audit and weaker trust
During internal control or disagreement someone has to reconstruct history. That costs time and creates unnecessary risk.
Choose your perspective. Needs differ.
Clients
Verify submissions before approval. Follow decisions and evidence across the project and portfolio with a clearer audit trail.
Contractors
Create clearer submissions, faster feedback and a stronger link between completed work, status and billing.
Project teams
See status, open items and ownership earlier. Spend less time chasing the right file version when measurement needs to move on.
Executives
Make contract data useful for governance. Compare projects, spot patterns earlier and prioritise where risk is growing.
From quantity to decisions you can explain
Quantity
Work is tied to Bill of Quantities items instead of standalone spreadsheets.
Evidence
Calculations and supporting documents are linked to the submission so review has something solid to assess.
Review
Parties see the same status, comments and history in one shared workflow.
Decision
Approvals are recorded with time, owner and supporting evidence.
Commercials
Settled value, variances and forecast inputs build on the same chain.
The Bill of Quantities as a shared hub
CASAI makes the BoQ the workspace where submissions, status and review belong together. That is the difference between chasing files and following the process.
From scattered information to traceable commercial control
Without a shared workflow
- Excel, email and personal folders as parallel truths
- Unclear which evidence belongs to which submission
- Long review lead times and growing open items
- Portfolio and forecast work rebuilt manually afterwards
With CASAI
- One chain from quantity to evidence, review, decision and commercials
- Clear status and ownership across roles and parties
- History that holds up in internal control and follow-up
- The same structured data for project and portfolio views
Verification is not admin. It is risk control.
Adjustments in reviewed submissions
In accumulated data in CASAI, adjustments of up to 6 percent have been observed in reviewed interim measurement submissions.
Spread in quantity changes
Accumulated data in CASAI shows a 28.4 percent spread in quantity changes, illustrating the need for verification.
A shared way of working
When clients and contractors share the workflow, personal dependency and after-the-fact reconstruction decrease.
Figures come from accumulated data in CASAI (claims C016 and C017). They describe observed patterns, not a guaranteed outcome in your project.
Used by organisations in construction and infrastructure
I see a very interesting efficiency gain internally — we no longer need to spend as many hours preparing the measurement reports every month. The whole project team now has one platform to work on together to gain better control of the quantity measurement process.
CASAI has helped me pay the contractor correctly for completed work, stay in control of the project's progress and make the project clear with easy-to-read views — and with that gain a good financial overview and more reliable forecasts for the project.
Common questions
Does CASAI replace Excel completely?
No. CASAI does not replace every spreadsheet or document tool. The platform structures the contract-near chain where quantities, evidence, review, decisions and commercial outcomes need to stay connected, so Excel is no longer the only source of truth in the project.
Does CASAI work for both clients and contractors?
Yes. Clients, contractors and internal project roles can work in the same traceable workflow, or one party can start internally and invite the other later. The value differs by role, which is why each audience has its own page.
Does the whole organisation need to start at once?
No. A common first step is a single project or a limited part of the portfolio where traceability and commercial settlement matter most. The way of working can then expand step by step.
How is CASAI priced?
Pricing depends on project configuration and which modules you need. The pricing page includes an ROI calculator to help estimate value. Book a walkthrough for a concrete setup.
Need specialist support on the project as well?
CASAI is the platform. Diagona also provides quantity measurement and valuation services, quality assurance and advisory support when you want expert help with calculation and review, often together with CASAI.
