Liaison Committee

The Liaison Committee of International Associations of Civil Engineering is a body initiating contact between international associations of civil engineering. Formed in 1958, it brings together the member organisations. Chairmanship and Secretariat rotate among member associations every 2 years.

The current position for the years 2023 and 2024.

Who we are?

CIB is a worldwide network of more than 3,000 experts from 95 organisations focused on all aspects of research and innovation in building and construction.

CIB Members are institutes, companies and other types of organisations involved in research or in the transfer or application of research results. Member organisations appoint experts to participate in CIB Commissions.

CIB is the acronym of the abbreviated French (former) name: “Conseil International du Bâtiment” (in English: International Council for Building). In 1998 the abbreviation was kept but the full name changed to the International Council for Research and Innovation in Building and Construction.

ECCS is the ONLY organisation which brings together the Steel Industry, the Fabricators and Contracting specialists, and the academic world through an international network of construction representatives, steel producers, and technical centres.

ECCS is a federation of 18 national associations of steel constructors as full members. it gathers also associate and supporting members, and since recently company members. This will help a closer cooperation with upstream and downstream players such as architects, civil engineers and companies related to steel construction to seat around the table for the benefit of the whole industry and to enhance discussions between researchers and the industry.

The fib, Fédération internationale du béton, is a not-for-profit association formed by 42 national member groups and approximately 2'500 corporate and individual members in more than 100 countries. The fib’s mission is to develop at an international level the study of scientific and practical matters capable of advancing the technical, economic, aesthetic and environmental performance of concrete construction.

The knowledge developed and shared by the fib (fib Bulletins, fib events, fib workshops, fib courses, etc.) is entirely the result of the volunteer work provided by the fib members.

The International Association for Bridge and Structural Engineering (IABSE) is a scientific / technical Association comprising members in 100 countries. Founded in 1929 it has its seat in Zurich, Switzerland. 

IABSE deals with all aspects of structural engineering: the science and art of planning, design, construction, operation, monitoring and inspection, maintenance, rehabilitation and preservation, demolition and dismantling of structures, taking into consideration technical, economic, environmental, aesthetic and social aspects. The term 'Structures' includes bridges, buildings and all types of civil engineering structures, composed of any structural material.

International Association for Shell and Spatial Structures (IASS), founded by Eduardo Torroja in 1959, is a non-profit organization.

It has as its goal the achievement of further progress through an interchange of ideas among all those interested in lightweight structural systems such as lattice, tension, membrane, and shell structures, in particular architects, engineers, builders and academics.

The Association welcomes to membership all individuals and organizations who share its aims.

The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM, from the name in French) was founded in June 1947, with the aim to promote scientific cooperation in the area of construction materials and structures.

Today, the new meaning of the acronym RILEM (Réunion Internationale des Laboratoires et Experts des Matériaux, systèmes de construction et ouvrages) emphasises its dominant focus on people as well as its worldwide activities, covering 90 countries.

Global Consensus on Sustainability in the Built Environment

Read more

The objective of the Global Consensus on Sustainability in the Built Environment – GLOBE - is to direct the attention of the global community, politicians, industry leaders, and societal decision-makers to the critical importance of the built environment for sustainable development at global and local scales. Appropriate actions by all parties addressed are urgently required to ensure that the built environment of the future is resilient, adequately safe, and socially, environmentally and economically sustainable.

Nothing less than a transformative and united worldwide effort from all stakeholders of the construction sector is required for human society to be successful in sustainable development, and in the mitigation of the disastrous consequences of climate change at global and local scales.


The Joint Commission on Global Consensus is to promote the flow of knowledge, ideas and collaboration between the LC member associations.

The JCGC aims to raise awareness and promote the GLOBE Consensus, develop new, unbiased, science-based knowledge to support global sustainability in the built environment, and establish foundational standards for sustainability regulation. It synthesizes and disseminates expertise from partners and supporters, highlights the importance of sustainable development to researchers, organizations, and stakeholders, and prepares key documents such as White Papers and reports.

The JCGC also facilitates the sharing of experimental data, oversees educational and training activities on sustainability, and collaborates with other organizations to promote the GLOBE Consensus and connect stakeholders worldwide.


Joint Committee on Structural Safety

The JCSS is a committee in the field of Structural related Risk and Reliability, acting on behalf of the Liaison Committee.

Read more

In 1971, the Liaison Committee which co‐ordinates the activities of six international associations in civil engineering, composed of CEB, CIB, fib, IABSE, IASS and RILEM, created a Joint Committee on Structural Safety, JCSS, with the aim of improving the general knowledge in structural safety. The JCSS under the chairmanships of the late Prof. J. Ferry‐Borges, Portugal, followed by Prof. J. Schneider, Prof. R. Rackwitz, Prof. T. Vrouwenvelder, Prof. M. H. Faber, Prof. J. D. Sørensen, Dr. Inger B. Kroon and presently Prof. M. H. Faber.

JCSS continuously has two meetings every year since 1971. During these meetings, more than 250 papers on structural safety and related matters have been discussed. Several documents of general character and interest have been prepared and published. These documents supplied the background for the preparation of guidance documents concerning the design and construction of different types of structures and materials, among others several ISO documents, Eurocodes and the CEB and ECCS Model Codes.
