Spain-based contractor Lezama Demoliciones has secured its first public contract for demolition works involving the use of BIM (Building Information Modeling), marking a key step forward in the company’s ongoing efforts to contribute to sustainable development in the country.

The project will see the demolition of a 20-metre high structure located in Spain’s Basque Country region.

Lezama will carry out selective dismantling works to take down the structure, which is situated in close proximity to three other similar buildings.

“The use of digital BIM tools will allow the company to more efficiently approach the planning and execution of demolition, while ensuring an accurate assessment of the environmental and social aspects associated with the process,” said Lezama.

Speaking exclusively to D&Ri, the company revealed that it will be using the Edificius software, which integrates 2D and 3D architectural design tools with rendering, scene photomontages, video editing and virtual reality, from Acca Software.

Lezama has also brought in specialist IBBIM Arquitectura for the project, with the company’s chief BIM modeler, Iñigo Barbero, taking charge of the digital applications.

Erik Sandonis Martin, Research & Development Manager at Lezama Demoliciones, said: “It is a pioneering project in Spain, as it is the first public project to require BIM criteria in the tendering and execution phase.

“Lezama Demoliciones is testing its digital developments for the first time in a real demolition contract.”

The company was awarded the contract by VISESA, a Basque Government-owned organisation responsible for housing and land.

While the value of the contract was not disclosed, Lezama told D&Ri that the project will start this February and that the works are expected to take just three months.

The company added: “This particular project highlights the importance of pre-demolition audits, a key practice that Lezama Demoliciones has perfected over time.

“These audits play a crucial role in assessing the amount of waste in a demolition project, while also calculating the environmental impacts arising from the specific procedures carried out.”
