In 2003 the UIC set up the working group “Masonry Arch Bridges” which managed the projects I/03/U/285 ”Improving assessment, optimisation of maintenance and development of database for masonry arch bridges” (2004 – 2007) and “Assessment of masonry arch bridges” (2011 – 2015). During this period the project was coordinated by Zoltán Orban (MAV).
The results of the complete work during the project have been introduced in the IRS 70778-3 “Recommendations for the inspection, assessment and maintenance of masonry arch bridges”, published by UIC in 2018.
The background documents providing further information and guidance are available in UIC Extranet to registered users. In 2019 the PoSE (Panel of Structural Experts) decided to make openly available selected background documents, one of which is the “Guide for execution and control of repairs – Cleaning manual”. This document has been elaborated by José Antonio Martín Caro (INES) and Keith Ross (Network Rail).
