You have arrived at the website of E-Quantities Ltd. providers of computer generated quantities to the UK construction industry since 2003.

Read on to find out more about computer generated quantities, and follow the links to our freeware download area to get some useful QS and Estimation utilities.

BQFilter is a useful utility to convert your Bills of Quantity files between a number of different file formats including native Calculix, MS Excel, native ConQuest and the industry standard CITE format.

We have made this utility available as freeware (privately AND commercially) to promote the use of electronic Bills of Quantities. Other functionality will be added as we find a need, so check back regularly for upgrades to the BQFilter program.

Our other freeware offering is QSOnscreen. A utility which we use to measure areas and lengths by outlining over screen images of drawings. In "cut and fill" mode you can enter existing and finished levels onto your outlined areas then calculate earthworks and disposal volumes at the press of a button. If you check out the competition, to get functionality like this you can expect a bill well into the 000's usually accompanied by an annual support charge. You can use QSOnscreen privately AND commercially for FREE... All we ask in return is if you find it useful, let someone else know who might also find it useful. If you want to read about the linear and bi-linear interpolations and extrapolations involved in the cut and fill calculations, it is all explained in the introductory tutorial which accompanies the program.

All our production quantities projects are measured using Highbrave Ltd.'s software on FreeBSD which is equally accessible in real-time to workstations within our local area network or remotely from anywhere with an Internet connection.

Also under a FREEWARE licence, you can download a fully functional version of Calculix with no restriction on time limit or functionality. So you don't have to take our word that it's an excellent QS program. You can try it for yourself. Read on for more details...
