Services
Which area do you need help with?
Three specialist services for quantities, contracts and follow-up. Under 04 you will find surveying in the field.
01 / Quantities
Quantity regulation
We review quantity claims, measurements and invoice documentation against the contract. Payment should correspond to the work carried out.

Contract management and client support
We read the contract documents and follow variations and additional works. Responsibilities and decisions are kept together.
03 / Follow-up
Digital contract management
Quantity claims, documentation, review and finances in one flow in CASAI, with reports for follow-up.
04 / Surveying
Production surveying with as-built surveying and setting out for railways, civil engineering and buildings. Drone surveying and laser scanning when the site or building needs to be documented.
How we can help
Choose how you want support.
The services can be bought in different ways. You keep decisions and approval in all of them.
CASAI brings claims, supporting documents, dialogue and decisions together in one flow. Diagona is the product owner of the platform.
Contract Control Advisory
A specialist question
An assessment of a quantity, a variation or unclear documentation. Defined and documented.
Managed Contract Control
Ongoing control
Diagona runs an agreed control function, with or without CASAI. You keep decisions and approval.
Enterprise
Several projects
The same way of working across several projects. Enterprise is scale, not a separate package.
Three assignments, the same need for control
The right documentation is needed both in production and when quantities are regulated. The case studies show how Diagona and CASAI support clients and contractors with traceable documentation and clearer decisions.
