The International Union of Laboratories and Experts in Construction Materials, Systems and Structures

DAC - Development Advisory Committee

Within DAC (Development Advisory Committee), strategies for the development and improvement of RILEM?s membership profile and its international partnerships are discussed. DAC advises the Bureau on international developments, activities and relations, aiming at increasing and improving international collaboration between RILEM and its international industrial and professional partners. DAC is also tasked with developing strategies to grow RILEM membership and to facilitate cooperation among its various member groups from around the globe.

TAC - Technical Activities Committee

TAC monitors the work of the Technical Committees (TCs) and other technical activities of RILEM, and its responsibilities include the following:

• Proposal and recommendation of new TCs;
• Review of the on-going work of TCs and facilitating progress;
• Approval of proposals for workshops, conferences and other events co-sponsored by RILEM;
• Proposal of representatives in sponsored congresses and conferences;
• Discussion of new trends and identification of potential TCs.

RYC- RILEM Youth Council

RYC was created at the 74th Annual Week in " Sheffield", UK, in September 2020, as a sub-committee of DAC.

Its main tasks are:

• attracting, involving and motivating young RILEM members
• encouraging participation in TAC and EAC activities
• increasing awareness on RILEM events and courses
• preparing young members for leadership positions
• showcasing / celebrating the achievements of the RILEM Youth
• creating networks between emerging researchers to increase visibility of / access to RILEM.

RYC is formed by 11 PhD student members, 10 of which are representing each RILEM region and 1 nominated by the DAC chair, for a 3 to 4 years mandate.

EAC - Educational Activities Committee
One of the main purposes of the Educational Activities Committee (EAC) of RILEM is to broaden the education of both PhD students and the professional community through promotion of interesting and informative one-week PhD courses and seminars on subjects of relevance to researchers working in specific areas. RILEM EAC is responsible for RILEM activities in the field of education. These include a number of different tasks, of which the basic and most important one is the courses to which we grant scientific sponsorship. Though RILEM EAC has only existed for a handful of years, our sponsored courses have been enjoyed by more than 2000 participants and about 200 teachers.

TC - Technical committees

The Technical Committees are the heart of the scientific activity of the association. The main forum where RILEM members meet and exchange their expertise. RILEM TCs play a major role in furthering scientific knowledge.

A TC is a group of international experts working together in a particular field in order to: 

• assemble and evaluate research data
• harmonise testing methods 
• suggest new topics for research (this research not to be directly undertaken by RILEM TCs)

and to promote their conclusions by publishing recommendations, technical reports or state-of-the-art reports for test methods or construction practice.

A RILEM TC is in direct connection with a RILEM Cluster. This body is entrusted with co-ordinating and monitoring RILEM TC activities, and to advise the RILEM Technical Activities Committee (TAC). This co-ordination is convened by Clusters? conveners.

GLOBE, Global Consensus on Sustainability in the Built Environment

GLOBE was initiated at an interdisciplinary workshop held at Tongji University, Shanghai, China co-organized by members of the Joint Committee on Structural Safety (JCSS) and the International Joint Research Center for Engineering Reliability and Stochastic Mechanics (CERSM) at Tongji University. GLOBE has since been adopted by the JCSS and is supported by major international associations within the construction industry, including RILEM, IABSE, CIB, ECCS, fib and IASS.

The GLOBE working team operated under the direction of Prof. Michael Havbro Faber, Department of the Built Environment, Aalborg University, Denmark, President of the Joint Committee on Structural Safety and initiator of GLOBE, assisted by Dr. Dipl.-Ing.
