History

1
2014
Successful implementation of the software on the foreign market.
2
2013
Successful implementation of the software in the domestic market.
3
2011
Final phase of MK.III software development.
4
2010
Successfully passed 2000 measurements mark.
5
2009
Mk.III hardware introduced to the market.
6
2008
High-speed connectivity to the mobile network and encrypted VPN network engaged.
7
2007
Web-based applications for remote control and access to the systems were developed.
8
2006
Camera was implemented in measurement for preselection together with handheld computer.
9
2005
Passed 300 measurements mark in other countries around the world.
10
2003
First successful real time FAD (Free of Axle Detector) measurements on a 6-m long bridge and on a 500-m long orthotropic deck bridge.
11
2000 to 2003
SiWIM hardware and software was completely redesigned.
12
1999
Cooperation between ZAG and Cestel initiated to commercialize the SiWIM prototype.
13
1994 to 1999

Bridge WIM methodology is considerably upgraded in the COST323 action and in the EC 4th Framework project WAVE, resulting in:

— increased accuracy of results,
— extended applicability to a wide range of bridge types, such as short concrete slabs, box culverts, integral construction, long-span bridges, including box girders and orthotropic decks.

14
1990
New prototype versions of Bridge WIM (B-WIM) systems were developed independently in Slovenia and in Ireland.
15
1986
A similar system using culverts is developed in Australia where there are today around 200 such systems in operation.
16
1979
Prof. Fred Moses develops bridge WIM concept of using bridges as scales to weigh trucks in motion as an alternative to more established pavement WIM systems.
