Engineering Service Levels & Professional Responsibility

Rezali offers five defined levels of engineering service. Each level reflects a different allocation of responsibility for engineering design, drafting, detailing, and regulatory accountability, in accordance with applicable provincial engineering legislation, codes, and standards.

Selecting the appropriate level depends on:

  • Project phase

  • Technical risk

  • Regulatory requirements

  • Existing design maturity

  • What this level means
    Engineering design, drafting, and detailing are performed by others. Rezali reviews the completed engineering work, verifies compliance with applicable provincial codes and standards, and—where appropriate—issues engineering documents under the professional seal required in the province of installation.

    Typical use cases

    • Structures or equipment designed outside the installation jurisdiction

    • Manufacturer-engineered systems requiring local professional validation

    • Projects entering permitting, procurement, or construction

    How this works in practice

    1. Confirm jurisdiction and applicable regulatory framework

    2. Establish local design criteria and governing codes

    3. Perform detailed engineering review of drawings and calculations

    4. Identify and resolve non-conformities or gaps

    5. Issue validated engineering documents under seal

    Indicators of success

    • Acceptance by authorities having jurisdiction (AHJs)

    • No late redesigns due to code conflicts

    • Clear traceability between reviewed and sealed documents

    When this level is not recommended

    • Early or conceptual design stages

    • Incomplete or undocumented engineering

    • High-risk structures with uncertain assumptions

    What can go wrong if misused

    • Insufficient technical verification (“rubber-stamping”)

    • Lack of authority to require design changes

    • Undetected non-compliance with local codes

  • What this level means
    Engineering design and drafting are performed by others, while Rezali provides engineering supervision from the beginning of the design process and ultimately assumes professional responsibility for the final engineering documents.

    Typical use cases

    • Design-build or manufacturer-led projects

    • Multi-party design environments

    • Projects where regulatory risk must be managed early

    How this works in practice

    1. Early appointment of Rezali as supervising engineer

    2. Definition of design basis, codes, loads, and assumptions

    3. Structured reviews at key design milestones

    4. Ongoing technical direction and issue resolution

    5. Final verification and issuance under seal

    Indicators of success

    • Reduced late-stage design changes

    • Clear alignment between design intent and final output

    • No regulatory surprises at submission or construction

    When this level is not recommended

    • When core design decisions are already fixed

    • When Rezali has no authority to influence design

    What can go wrong if misused

    • Supervision starts too late

    • Engineer acts as reviewer instead of design authority

    • Design assumptions remain undocumented

  • What this level means
    Rezali performs all engineering analysis and design. Drafting and shop-level detailing are executed by others under Rezali’s technical direction.

    Typical use cases

    • Projects requiring strong engineering control

    • Clients or fabricators with in-house drafting capacity

    • Moderate- to high-risk structures

    How this works in practice

    1. Engineering design and calculations by Rezali

    2. Clear documentation of design intent and assumptions

    3. Drafting and detailing by external resources

    4. Engineering review of all drawings

    5. Issuance of documents reflecting Rezali’s design

    Indicators of success

    • Clear separation between engineering and drafting

    • No unauthorized design decisions at drafting level

    • Smooth transition to fabrication

    When this level is not recommended

    • When drafting resources lack industrial experience

    • When rapid, integrated iteration is required

    What can go wrong if misused

    • Drafting deviates from engineering intent

    • Design changes introduced without engineering review

  • What this level means
    Rezali delivers complete engineering design and construction drawings. Shop-level detailing is performed by others to suit fabrication processes.

    Typical use cases

    • Steel and industrial structures

    • Fabrication-driven projects

    • Projects aligned with CSA S16 and CISC practices

    How this works in practice

    1. Engineering design and drawings prepared by Rezali

    2. Fabricator develops shop drawings

    3. Engineering review of structural adequacy and load paths

    4. Resolution of deviations affecting design intent

    Indicators of success

    • Shop drawings align with engineered intent

    • No fabrication rework due to engineering conflicts

    • Clear approval and revision records

    When this level is not recommended

    • Projects with unclear design intent

    • Highly novel or non-standard systems

    What can go wrong if misused

    • Shop details alter structural behavior

    • Fabrication optimizations compromise design assumptions

  • What this level means
    Rezali provides full engineering services from concept through fabrication support, with a single point of technical and professional responsibility.

    Typical use cases

    • High-risk or safety-critical projects

    • Complex industrial structures

    • Projects requiring maximum regulatory defensibility

    How this works in practice

    1. Integrated engineering, drafting, and detailing

    2. Internal quality control and independent checks

    3. Ongoing fabrication and construction support

    Indicators of success

    • Single accountable engineering authority

    • Minimal coordination risk

    • High confidence in compliance and constructability

    What can go wrong

    • Typically lowest-risk model

    • Issues are usually related to project complexity, not responsibility gaps

  • When clients contact Rezali, we assess:

    • Project phase and maturity

    • Regulatory environment

    • Technical complexity and risk

    • Existing engineering deliverables

    We then recommend the lowest service level that still provides adequate engineering control, ensuring compliance without unnecessary cost or duplication.
