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
Confirm jurisdiction and applicable regulatory framework
Establish local design criteria and governing codes
Perform detailed engineering review of drawings and calculations
Identify and resolve non-conformities or gaps
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
Early appointment of Rezali as supervising engineer
Definition of design basis, codes, loads, and assumptions
Structured reviews at key design milestones
Ongoing technical direction and issue resolution
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
Engineering design and calculations by Rezali
Clear documentation of design intent and assumptions
Drafting and detailing by external resources
Engineering review of all drawings
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
Engineering design and drawings prepared by Rezali
Fabricator develops shop drawings
Engineering review of structural adequacy and load paths
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
Integrated engineering, drafting, and detailing
Internal quality control and independent checks
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.
