Structural Engineering Services

de Koning Group offers a full range of structural engineering expertise, including:

  • Fabrication-ready steel designs for buildings, docks, and accessory structures.

  • Precision plans for timber and timberframe structures to ensure proper assembly.

  • Engineered designs for poured concrete foundations in residential, commercial, and waterfront applications.

  • Comprehensive structural engineering for custom boathouses in Muskoka, Lake of Bays, Georgian Bay, and surrounding Ontario regions.

Muskoka & Ontario Engineering Specialists

Building in Muskoka or other Ontario regions requires expertise in both structural and civil engineering to address unique site conditions such as:

  • Steep slopes and bedrock

  • Waterfront setbacks and shoreline regulations

  • Seasonal freeze/thaw conditions

  • Septic systems and stormwater management

  • Municipal zoning and environmental compliance

Our engineers integrate these considerations into every design to ensure structures are safe, durable, and fully compliant with local and provincial regulations.
