The Calculix system establishes a "Data-base" of the measurement
information of a Building which can then be manipulated to produce the Bills of
Quantity in the required format and all other post contract documentation.
The principal aim of the system is to produce accurate Bills of Quantities
quickly and efficiently.
The long term objective is to extend the use of the Quantity Surveyor's
measurement beyond Bills of Quantities and into any function that uses
measurement data. Obviously this includes Valuations, Fluctuations and
Variations but it also aims to produce Material Schedules, Project Programming,
Heat Loss calculations, Pipe sizing and Lighting calculations.
Both the versions of Calculix available for download below are multi-user
programs allowing simultaneous access to project data from several (unlimited)
It is offered for download under a freeware licence to promote the use of

When you have read, understood and accepted these freeware licence terms
please read on to download Calculix.
We are sad to report that as of March 2009, Highbrave Ltd was dissolved and so
it appears that the Calculix QS Measurement system will not now be restored to
its former "cutting edge" status. However, the legacy versions which
remain still have much to offer to those willing to spend the time on learning
how to use them so they will remain available for download here.
Download Calculix v6.0 for Windows (Works okay on all versions of windows after and including 9x)
Download Calculix v5.4 for FreeBSD (Note:
requires Compat2.X legacy support for FreeBSD so we recommend getting a legacy
FreeBSD 4.10 box to run it on. Compatibility packs for later FreeBSD releases
only go back to version 3)
Advice on remote operation of Calculix on FreeBSD
Have a read through the comprehensive online manual.
If you prefer, you can download the complete
manual here to read off-line.
As well as an in depth explanation of Calculix features, this manual describes keyboard operation of the unix versions. The
standalone windows version is similar but some cursor movement shortcut keys are different.
Some sections of the manual are not applicable to modern networks but are
included for the benefit of users still operating on older unix systems. These
sections are noted as such.
