Expertise turned into a scalable way of working
CASAI has grown out of Diagona's specialist work in quantity measurement, commercial contract management, construction law and technical project controls. The platform scales a way of working developed in real construction and civil engineering projects.
Our mission and vision
Our mission
Lead development and create innovations that move the industry forward.
Our vision
Create a better climate between the parties, make work processes more efficient and reduce disputes in the quantity settlement process.
The problem we saw in project after project
Scattered evidence
Quantities, evidence, comments and decisions were handled in files and emails that did not stay connected.
Person dependent control
The quality of the settlement depended on individual people's routines and memory.
The same work over and over
Every project built its own structure instead of reusing a proven way of working.
Two brands, one way of working
Diagona
The specialist company. Expertise, methodology, objectivity, advisory services and delivery in construction and civil engineering projects.
CASAI
The product and platform. Workflow, structure, traceability, collaboration, data, BI and AI support.
The core principle
Expertise drives the platform. The platform scales the expertise.
Our journey
2015: The idea is born
The need is identified in real projects and the idea of CASAI is born.
2016: The solution takes shape
Mockups and wireframes are produced in the project group and the required functionality is discussed.
2018: Development begins
Programming and testing of the platform begins.
2020: CASAI launches
CASAI launches after hard work by the project team.
We saw a need for a platform that quality assures the commercial settlement process in construction and civil engineering projects. That is how the idea of CASAI was born.

Principles that guide our work
Objectivity
Evidence, method and assumptions are stated openly, in the product and in our advisory work.
Respect
We build for all parties in the project: shared rules of the game instead of one sided control.
Innovation
We develop the platform close to real projects, with new technology as decision support, not as an end in itself.
Commercial integrity
The value must be possible to explain and follow up, for customers, partners and in our own commitments.
Sustainability
Better control of resources
A structured quantity settlement process gives better control of the project's financials and resource use.
Support for your sustainability goals
A traceable and documented way of working can support your organisation's work with the UN Agenda 2030 and ESG reporting.
