Heritage buildings are typically constructed using traditional methods and materials of varying quality. Managers of these buildings face complex preservation challenges, notably because the construction often does not comply with modern codes and standards, plans and other construction details are frequently unavailable or incomplete, and any work must maintain the unique appearance and character of the heritage structure.
SIMCO supports diverse projects, including:
We characterize the existing structure to select the optimal materials and repair strategies, ensuring compatibility and harmonization of interventions.
We provide solutions that ensure the preservation of original functions or the thoughtful repurposing of heritage buildings, balancing technical performance, compliance with modern standards, and respect for the historical identity.
