Evaluation of Existing Structures

Rezali provides engineering evaluation and structural assessment services for existing industrial structures and buildings. These services support owners and operators in understanding current structural performance, regulatory compliance, and suitability for continued or modified use.

Evaluations are conducted in accordance with applicable provincial engineering regulations, codes and standards, and recognized engineering practice, and may support operational decisions, upgrades, or corrective actions.

  • Depending on project needs, Rezali’s evaluation services may include:

    • Structural diagnosis of performance issues
      Assessment of vibration, excessive deflection, cracking, or other serviceability-related concerns affecting industrial structures and equipment supports.

    • Code-based evaluation of existing buildings and structures
      Evaluation of industrial buildings, including large-roof structures, for snow loads, wind loads, and other environmental effects in accordance with applicable codes and site-specific conditions.

    • Assessment for changed or increased demands
      Evaluation of existing structures where operational requirements have changed, such as:

      • Added equipment or loads

      • Modified usage

      • Updated safety or performance expectations

    • Engineering judgement and recommendations
      Identification of structural deficiencies, reserve capacity, and practical options for mitigation or improvement.

  • Clients typically request this service when:

    • Existing structures exhibit unexpected behavior (vibration, movement, distress)

    • Operational changes are planned

    • Regulatory or insurance reviews are required

    • Environmental loads have increased due to code updates or site conditions

    • Structural upgrades or life-extension decisions are being considered

    • Scope and objective definition
      Clarify the purpose of the evaluation and applicable regulatory context.

    • Document review and data collection
      Review available drawings, calculations, and historical information.
      Site observations may be conducted as required.

    • Engineering analysis and assessment
      Perform analytical evaluation using current codes, standards, and engineering judgement, accounting for the nature of existing construction.

    • Findings and conclusions
      Identify observed issues, compliance status, and structural performance relative to the defined objectives.

    • Recommendations (as applicable)
      Provide engineering recommendations for monitoring, mitigation, repair, or upgrade where warranted.

    • Clear understanding of structural condition and performance

    • Actionable, defensible engineering conclusions

    • Alignment with regulatory and code requirements

    • Support for informed operational or capital decisions

    • Does not constitute a general building inspection

    • Does not guarantee future performance beyond stated assumptions

    • Does not replace ongoing maintenance or monitoring unless explicitly defined

  • Existing structures are often subjected to:

    • Loads and conditions not considered in the original design

    • Evolving codes and standards

    • Changing operational requirements

    A structured engineering evaluation reduces uncertainty, manages risk, and supports safe, compliant, and cost-effective decisions.

  • This service may be delivered under different Engineering Service Levels, depending on scope:

    • L1 — Review and validation of third-party structural assessments

    • L3 / L4 — Rezali-led evaluation with external drafting or detailing

    • L5 — Full evaluation, analysis, and upgrade design
