A 130-square-meter structure that will allow measurement of seismic behavior, humidity and temperature
The CLT experimental tower that is being developed together with CMPC Maderas SpA., Alto Horizonte Ltda., Simpson Strong Tie Chile Ltda., JMS Ingenieros Consultores Ltda., Premad Ltda., Forestal Tricahue Ltda., Constructora IMB Ltda., Oxiquim SA , Maderas Cortelima and experts from the University of Biobío (UBB) will be five floors, 130 square meters in size and made entirely of cross-laminated Radiata Pine timber. The only 'but' is that it will not be habitable due to the restriction of current Chilean construction regulations for buildings of this type, precisely those restrictions sought to be changed based on studies and cases of this type. This project will be located on the UBB Concepción campus at the end of 2020.
In the words of José Pablo Jordán, CMPC's Deputy Manager of Product Development, “the project is a productive linkage between the university, suppliers, small businesses and us, so there is value in associativity and productive linkage. The tower will have the possibility of testing different materials and solutions, demonstrating that there are solutions with wood such as CLT, tested around the world for the manufacture of first-rate high-rise buildings and that can be applied in Chile. Finally, to get rid of the paradigm that wood is only for social housing."
For his part, Víctor Rosales, director of the project and an academic at UBB’s Faculty of Architecture, Construction and Design, assured Corma.cl that “as it is an experimental building, we have a test plan and trials conducted by the Architecture Faculty’s Department of Construction Sciences, starting from the construction stage, to obtain productivity and cost parameters and matching the BIM experience (an integral way of conducting a project, planning and construction.) There will be structural evaluations carried out in the building by the Department of Civil Engineering as well as performance evaluations measuring temperatures, humidity and acoustic issues jointly with the CITEC research group of the UBB.”
What is CLT?
CLT (Cross-Laminated Timber) is cross-laminated wood that is industrially manufactured in the form of large, light-weight boards. These sheets of timber currently play a fundamental role in Austrian, German, Italian and Swedish architecture - countries that already have CLT buildings up to nine stories high. One of its greatest characteristics is its low carbon footprint and low thermal conductivity, which makes it a highly energy-efficient material that is very easy to industrialize.
El cambio climático y el crecimiento demográfico están íntimamente relacionados.
La construcción de edificios puede ser más verde. Y la madera ofrece un conjunto de ventajas y beneficios que por años fueron ignorados.
Pese a todas las ventajas, la construcción en madera en altura enfrenta desafíos. Uno es ganarse el espacio en la mente de las personas: que para nadie sea increíble la construcción de un edificio de 30 pisos en madera.
La madera se presta para la fabricación de partes y piezas, las que luego se envían para su ensamblaje in situ. Eso acorta los plazos y acrecienta la seguridad y precisión.
