Technology Innovation in Underground Construction (TUNCONSTRUCT Project)

Print PDF

TUNCONSTRUCT is a multi-disciplinary research project that promotes the development and implementation of European technological innovation in underground construction. Bustling at its core is the vigorous participation of some of Europe's best recognized names in the underground engineering industry.

The project's 41 partners, from 11 European countries, integrate not only the on-the-field engineering experience and technical know-how of the industry, but also the research capabilities and conceptual innovation of the academic sector.

TUNCONSTRUCT is fully committed to contributing to an increased quality of life for Europeans by reducing construction time and cost of planned and future underground infrastructures.

The project is co-financed by the European Commission, under its 6th framework program, which provides 54% of its 26 million Euro quadrennial budget. Coordination rests on the Graz University of Technology, Austria.

 

Integrated Tool For In Situ Characterization Of Effectiveness And Durability Of Conservation Techniques in Historical Structures (DIAS Project)

Print PDF

The main goal of the DIAS project is to develop a valid and cost-effective tool for in laboratory and in situ assessment of residual mechanical properties of building stones, as well as, stone consolidation treatments. This will be achieved through the design, construction and validation of an integrated portable tool including Micro-Drilling, Indentation and Acoustic devices and associated Software (DIAS). It also implies the development of a reference user-friendly database of standard and non-standard mechanical properties for a wide variety of stones, also useful, among others, in cases of repair by choosing appropriate stones in the quarries. This project-which should lead to a marketable equipment- is expected to improve our understanding of the degradation mechanisms -such as mechanical loads or various types of weathering- in damaged parts of historical buildings and monuments; it would also enable to better restoration practices for this important part of our cultural patrimony.

The main Project’s objectives can be summarized as follows:

- Design and construction of a portable, integrated device (DIAS) (apparatus, manual & software) for in laboratory and in situ reliable and cost-effective characterization of the strength and stiffness of stones.

- Development of reliable in laboratory and in situ testing as well as data back analysis procedures for the quasi-non-destructive estimation of elasticity and strength of stones.

- Development of a reference user-friendly database of in situ and in laboratory standard and non-standard (via DIAS) mechanical properties for a wide variety of stones and relevant software of the integrated DIAS instrument.
