Why General Review Is Critical for Part 3 Commercial Projects in Toronto
Getting a commercial space designed and permitted is only part of the process. For many Ontario Building Code Part 3 projects, what happens during construction can be just as important as the drawings that received the building permit.
Restaurants, retail spaces, offices, clinics, commercial renovations, and other Part 3 projects often involve several consultants, contractors, municipal inspections, equipment suppliers, and critical deadlines. A problem discovered late in construction can delay inspections, occupancy, and ultimately the opening of the business.
This is why retaining an architect from the beginning of the project through General Review and Construction Administration can be one of the most important decisions a commercial property owner or tenant makes.
At Linerra Architects, we approach commercial projects as a continuous process from design and permitting through construction and occupancy, helping clients reduce surprises and keep their projects moving toward opening day.
What Is General Review?
General Review is a professional service carried out during construction to assess whether the work is proceeding in general conformity with the drawings and documents that formed the basis of the building permit.
Ontario's Building Code contains requirements for General Review by architects and professional engineers on projects where professional design and review are required. The review involves periodic site visits based on appropriate sampling, documenting observed deficiencies, and reporting on the construction.
It is important to understand that General Review is not the same as continuous construction supervision.
The architect does not remain on site every day or direct the contractor's means and methods. Instead, the architect visits the project at appropriate stages to observe representative portions of the work and identify items that may not conform with the approved design.
The Ontario Association of Architects describes General Review services as including examining representative samples of the work, keeping the client informed regarding progress and quality, identifying observed defects or deficiencies, and reporting to the appropriate parties.
For a commercial project, these reviews can become particularly important as construction approaches critical inspection and occupancy milestones.
Why General Review Matters for Part 3 Commercial Projects
Part 3 buildings are generally more complex than typical small residential projects.
A commercial interior renovation may involve:
Fire separations and fire-resistance ratings
Exit and egress requirements
Barrier-free design
Plumbing and washroom requirements
HVAC and mechanical systems
Emergency lighting and life-safety systems
Sprinkler and fire alarm coordination
Structural modifications
Electrical systems
Commercial kitchen exhaust systems
Multiple engineering consultants
Municipal inspections and occupancy requirements
A seemingly minor construction change can affect several of these systems at once.
For example, moving a wall in a restaurant may affect an accessible path of travel, exit width, sprinkler locations, mechanical distribution, electrical devices, ceiling coordination, and potentially the approved building permit drawings.
When an architect remains involved during construction, these issues can often be identified and coordinated before they become expensive problems.
The Architect Who Designed the Project Already Knows the Project
There is a significant advantage to having the same architectural team remain involved from the beginning of design through construction.
By the time construction starts, the architect may already understand:
The client's operational requirements
The existing building conditions
The zoning and Building Code strategy
Discussions that occurred with the municipality
The reasoning behind important design decisions
Consultant coordination requirements
Permit comments and revisions
Critical life-safety elements of the design
That knowledge is difficult to recreate if a new architect becomes involved only after construction has started.
A drawing shows what was designed. The architect who developed the project also understands why it was designed that way.
That distinction can become extremely valuable when unexpected conditions are discovered on site.
Construction Rarely Happens Exactly as Drawn
Even with a well-coordinated permit set, commercial renovations frequently uncover conditions that could not be completely verified before demolition.
Existing ductwork may be located somewhere unexpected.
A structural condition may differ from the available drawings.
An existing fire separation may require remediation.
A contractor may discover that equipment cannot fit within the originally planned location.
A landlord requirement may change.
A supplier may substitute a product.
These conditions require decisions.
Without timely architectural involvement, contractors may make field changes that appear reasonable from a construction perspective but create Building Code, accessibility, coordination, or permit issues later.
When the architect is actively involved, the team can evaluate the issue, coordinate with the appropriate consultants, document necessary revisions, and establish a path forward.
The Most Expensive Problems Are Often the Ones Discovered at the End
For many commercial clients, the most important date is not the building permit date.
It is opening day.
Every additional week before opening can mean another week of rent, financing costs, payroll preparation, lost revenue, delayed staff training, and postponed marketing.
This makes the final stages of a commercial project particularly important.
Imagine discovering shortly before a final inspection that:
A required fire-rated assembly was constructed incorrectly
An accessible door does not have sufficient clearance
A plumbing fixture is missing
A required fire stopping condition was not completed
Construction differs materially from the permit drawings
Consultant documentation remains outstanding
Some deficiencies may be simple to correct.
Others may require demolition of completed finishes, revised drawings, consultant coordination, additional inspections, or permit revisions.
The earlier these issues are identified, the easier they generally are to address.
General Review and Construction Administration Work Together
General Review and Construction Administration are related, but they are not identical.
General Review focuses on periodically reviewing construction to determine whether it is in general conformity with the applicable permit documents and professional requirements.
Construction Administration can involve a broader range of services such as:
Responding to contractor questions
Reviewing shop drawings
Coordinating consultant responses
Reviewing proposed substitutions
Issuing supplemental instructions
Reviewing contemplated changes
Documenting site conditions
Coordinating design revisions
Reviewing progress during construction
Assisting with deficiency resolution
Supporting project closeout
The OAA specifically distinguishes Building Code General Review from broader contract administration services.
For a commercial client trying to open on schedule, having both services properly coordinated can make a substantial difference.
Site Reviews Should Start Before the Project Is Almost Finished
One of the biggest mistakes a commercial owner can make is treating General Review as something that happens only near the end of construction.
Some building components become impossible to review after finishes are installed.
Fire-rated assemblies may be concealed.
Fire stopping may disappear above ceilings.
Structural connections may be covered.
Plumbing and mechanical services may become inaccessible.
That is why the architect's involvement needs to be coordinated with the construction schedule.
Periodic reviews at appropriate stages allow potential deficiencies to be identified while the relevant work is still visible and relatively easy to correct.
Ontario's requirements for professional General Review contemplate periodic site visits and written documentation of deficiencies rather than simply a single inspection at the completion of construction.
Your Architect Can Become the Coordination Point
A Part 3 commercial project can involve a surprisingly large team:
Owner → Architect → Contractor → Structural Engineer → Mechanical Engineer → Electrical Engineer → Fire Protection Consultant → Landlord → Building Department → Inspectors
Without clear coordination, information can easily become fragmented.
The architect often acts as the prime consultant and central point connecting the design disciplines.
When an issue arises on site, the architect can determine which consultant needs to respond, whether the architectural drawings are affected, whether a permit revision may be necessary, and how the solution integrates with the rest of the project.
This reduces the risk of one consultant solving a problem while unintentionally creating another.
Changing Architects During Construction Can Add Complexity
There are situations where transferring a project to another architect is necessary.
However, bringing a new architect into a partially constructed project can add another layer of work.
The incoming architect may need to review:
Existing permit drawings
Consultant drawings
Permit comments
Previous revisions
Construction completed to date
Outstanding deficiencies
Existing correspondence
Field changes already made by the contractor
The architect may also need to determine what work can reasonably be reviewed after it has already been concealed.
Maintaining architectural continuity from the beginning of the project avoids much of this reconstruction of project history.
For clients with aggressive construction schedules, that continuity can be particularly valuable.
General Review Is About More Than Compliance
General Review is fundamentally an important professional and regulatory responsibility. Ontario's framework requires architects and professional engineers to undertake General Review where applicable and to determine whether construction is in general conformity with the documents forming the basis of the building permit.
But from a client's perspective, its value extends beyond compliance.
Good architectural involvement during construction can help:
Catch issues earlier.
Keep consultants coordinated.
Clarify design intent for the contractor.
Reduce last-minute surprises.
Document deficiencies.
Support municipal inspection and closeout processes.
And most importantly for many business owners:
Help move the project toward occupancy and opening day.
Planning a Commercial Project in Toronto or the GTA?
If you are planning a restaurant, retail store, office, clinic, commercial renovation, or other Part 3 project, consider the construction phase when selecting your architect, not only the permit drawings.
An architect who understands the project from its earliest stages can remain a valuable resource when construction begins and real-world conditions start challenging what was planned on paper.
At Linerra Architects, we provide architectural services for commercial projects throughout Toronto and the Greater Toronto Area, including feasibility, design, Building Code review, permit drawings, consultant coordination, General Review, and Construction Administration.
Our goal is to help clients move through design, permitting, construction, and occupancy as one coordinated process.
