Modernization, Code Compliance, and Preservation of the Buildings at Collège de Montréal

Collège de Montreal

Collège de Montréal
Montreal, Canada
1996-2025

Since 1996, SIMCO (formerly COSIGMA) has contributed to the modernization, code compliance, restoration, and maintenance of Collège de Montréal’s buildings. The building that currently houses Collège de Montréal was constructed in 1870, adjacent to the Grand Séminaire de la Montagne, built in 1857, on the historic site of the former fort established for Indigenous peoples in 1676. Built with massive load-bearing walls of ancestral stone, the structure reflects a unique and rich architectural heritage.

Preserving the Unique Character and Original Architecture

SIMCO has carried out numerous mandates, including structural inspections, condition assessment and structural integrity, design of modernization, strengthening and rehabilitation works, code compliance upgrades, and preliminary studies for new infrastructure projects. Beyond analysis and design, SIMCO supports the College in procurement processes and ensures quality control of executed works.

  • Structural inspections
  • Assessment of condition and structural integrity
  • Vibration studies
  • Stabilization of existing structures
  • Reinforcement of massive timber roof trusses
  • Construction of a multi-level platform for new teaching spaces
  • Redevelopment of a performance hall at L’Ermitage
  • Multiple mandates for foundation waterproofing and water control solutions
  • Infrastructure upgrades to increase the College’s electrical capacity
  • Reconstruction of a pedestrian bridge

An Approach Based on Minimal Intervention

SIMCO has built a lasting relationship with the College through rigorous methodologies focused on minimal intervention. This approach focuses on intervening only when essential, favoring repair or reinforcement instead of replacement to maximize structural longevity and ensure cost efficiency. Throughout its interventions, SIMCO has remained committed to preserving the College’s unique character and original architecture, respecting its heritage and identity. This philosophy is reinforced by close collaboration and effective coordination with partners and firms engaged by the institution, ensuring durable and harmonious solutions.
