Situation

A medical office building in Vaughan, Ontario was undergoing a planned expansion following the owner’s acquisition of an adjacent portion of the property. Part of the building had previously undergone non-permitted renovation work by a former owner, raising concerns about the structural integrity of the existing structure.

Before proceeding with further renovations, the owner required a professional structural assessment to evaluate existing conditions, identify potential deficiencies, and determine whether the structure was suitable to support the proposed expansion.


Engineering Scope

Engaged to perform a comprehensive structural assessment of the existing building, including review of visible framing conditions, load paths, and prior alterations.

The scope included identifying structural elements that were defective, undersized, or inconsistent with typical engineering practice, and providing clear recommendations and instructions for corrective measures.


Key Engineering Considerations

  • Evaluation of existing structural framing and load paths

  • Impact of prior non-permitted alterations on structural performance

  • Identification of undersized or improperly detailed elements

  • Structural adequacy relative to current and proposed use

  • Practicality and sequencing of remedial measures prior to renovation

  • Clear documentation suitable for decision-making and planning


Outcome

The assessment identified several critical areas where structural detailing was defective or inadequate. Detailed recommendations and corrective instructions were provided to address the identified issues and restore structural reliability.

The findings gave the owner clarity and direction on the necessary remedial actions, providing confidence in the existing structure and enabling informed planning for the next phase of renovation and expansion.


Pre-renovation assessments following non-permitted work underscore the importance of engaging a licensed structural engineer in Toronto to identify deficiencies, manage risk, and support informed planning decisions.
