7th WTA Colloquium – Maintenance of Concrete Buildings – June 10th 2022 – Delft

Strategies for the Conservation of Historic Concrete Structures

Concrete heritage buildings from the 20th century are at risk, due to the absence of recognition of the historic values of these buildings as well as to the lack of knowledge of the specific characteristics of historic concrete structures. Frequently, solutions developed for repair of contemporary structures are applied to historic concrete buildings, resulting in interventions which are neither compatible nor durable.

The scope of the lectures ranges from the possibilities of new investigation methods and procedures of condition assessment, from the application of innovative materials to the use of heritage precast concrete elements. In addition, main results from relevant case studies are presented.

The Colloquium aims at providing building owners, employees from planning and engineering offices, construction companies, concrete experts, architects and representatives of authorities, with the latest developments in the field of conservation of concrete historic buildings, as resulting from practice and from international research projects.

On behalf of the organizing team, the members of WTA – International (TC5 Concrete) and of the
JPI-CH CONSECH20 project, we cordially invite you to the 7th Colloquium WTA – Strategies for the Conservation of Historic Concrete Buildings and Structures.

4th Meeting

The 4th meeting of the CONSECH20 project was held last week (June 25, 2020) via video-call. The meeting had to be carried remotely due to travel restrictions arising from the COVID-19 pandemic situation.

The discussion focused on a questionnaire to survey the public perception of the 20th-century concrete architectural heritage both at the professional and public level. The outputs should help in defining the values of the buildings (societal, cultural, artistic, etc.) and the perception of their state of conservation.

The discussion was also focused on the preliminary results of the survey carried out in the case studies in Cyprus, Czech Republic, Italy, and The Netherlands and on the formulation of proposals for selected case studies.
