Our main product is Archie-M. It is a tool for analytical assessment of arch bridges and viaducts. It has tools to help engineers assess within the context of both Railway and Highway needs and though originally aimed at UK practice is also now accepted by UIC for use on international railways.

The latest version of Archie-M is 2.5.1. It has been tested on versions of Windows up to 10.

Maintenance and Support

We put a lot of work into both developing Archie-M and in supporting users. Support is provided by Bill and Hamish by email or telephone (but please email details, including relevant files and data before hand). After the first year, maintenance and support can be extended year by year.

Manuals and Guides

The basic Archie-M manual is provided in electronic form.

There is also a set of lecture notes on assessing masonry bridges which is available for sale.


Training is provided by Bill Harvey through his consultancy business Bill Harvey Associates Ltd. Please email support@obvis.com with enquiries.

  • Yes, thorough coverage of arch bridges
  • Yes, especially construction and assessment aspects
  • Yes, for greater appreciation of arch bridge construction and assessment and how relevant arch bridges remain to the maintenance of our transport network
  • Yes - to a colleague who carries out bridge assessments
  • Yes as working in HSU I'd thoroughly recommend this course, especially to a colleague dealing directly with arch design (ie a colleague of a higher grade)
  • Yes, as it identifies a lot of defects which would help them to fully assess what is occurring on structure
  • Yes, plenty of information and detail regarding a variety of topics
  • Yes, very good insight into failure mechanisms associated with arches and how to identify the various failure types
  • Yes, very informative, knowledgeable tutor. Explains exactly how the arches work and how they react to varying loads/thrusts. Also gives v good information on the problems/faults that can occur
  • Very informative in bridge construction and reasons for failure, assessment and repairs

Replies to request for general comments

  • Tutor was brilliant. Very easy to listen to and understand. Course perfect length Maybe should finish with site visit
  • I felt there could be much more in the way of solutions to problems with, masonry arch bridges eg, anchors, ties stitching.
  • It's hard to hear and take in much on bridge visits with so many people around
  • Perhaps more emphasis on repair techniques as often recommendations are expected as part of the assessment reporting process
  • May have liked site visits on both days. Extremely beneficial but somewhat daunting for a newcomer
  • Course length was good, all topics well covered
  • Go on site and take points with total station and use points in Archie program
