Before starting a commercial construction project, make sure five things are clear: what you are building, whether the property can support it, what the realistic total budget is, what approvals are required, and who will manage the project from planning through completion.
The biggest construction problems do not always begin during construction. Many begin earlier—with an unsuitable space, incomplete scope, unrealistic budget, unresolved design decisions or requirements discovered too late.
That is why a successful commercial Construction should start with pre-construction planning, not demolition.
Commercial Construction: The 7 Things to Know Before You Start
| Before You Start | Why It Matters |
|---|---|
| Define the scope | Prevents different interpretations of what is being built |
| Evaluate the property | Confirms whether the space can support the intended use |
| Establish the full budget | Captures more than visible construction costs |
| Review permits and approvals | Identifies requirements before work begins |
| Coordinate design and construction | Finds conflicts earlier |
| Build a realistic schedule | Accounts for approvals, materials and dependencies |
| Define responsibilities | Establishes who makes decisions and manages changes |
If these seven areas are reasonably clear, the project is in a much stronger position to move into construction.
1. What Is Pre-Construction and Why Does It Matter?
Pre-construction is the planning and investigation completed before physical construction begins.
It can include reviewing the proposed scope, site conditions, drawings, preliminary costs, permitting requirements, material availability, construction methods and schedule.
Its purpose is not to predict every possible problem.
Its purpose is to identify the problems that can reasonably be identified before construction starts.
Consider a business planning to convert a retail unit into a restaurant.
The space may look suitable during a walkthrough, but the proposed use could introduce different requirements for ventilation, plumbing, electrical service, cooking equipment, occupancy and approvals.
Finding that out before signing a lease or finalizing the design gives the owner more options.
Finding it out after construction begins gives the project fewer.
The earlier an important construction question is answered, the more flexibility the project team usually has to deal with it.
2. Is the Property Actually Suitable for Your Business?
A commercially attractive property is not automatically a construction-ready property.
Before committing to a location, consider whether the existing building can support what the business requires.
Important areas can include:
- Electrical capacity
- Plumbing locations
- HVAC and ventilation
- Structural conditions
- Fire and life-safety systems
- Accessibility
- Existing and proposed occupancy
- Landlord requirements
- Available building drawings
- Municipal approvals
This is particularly important when the new business will use the property differently from the previous tenant.
A retail store becoming a restaurant is one example.
An office becoming a medical or dental clinic is another.
The City of Calgary recommends consulting an appropriate design professional before financially committing to a commercial location because upgrades required to meet applicable building requirements can be costly.
Before asking “Do I like this space?” also ask “Can this space support what I need to operate here?”
3. What Should a Commercial Construction Budget Include?
A realistic construction budget should account for the complete project—not just labour, materials and finishes.
Depending on the project, costs can involve:
| Cost Area | Examples |
| Design | Architecture, engineering and consultants |
| Construction | Labour, materials and equipment |
| Site Work | Demolition and preparation |
| Building Systems | Electrical, plumbing, HVAC and mechanical |
| Interiors | Walls, flooring, ceilings, millwork and finishes |
| Permits | Applicable applications and approvals |
| Specialty Work | Business-specific systems or installations |
| Contingency | Allowance for appropriate project uncertainty |
One budgeting mistake is concentrating on what customers will see while overlooking what needs to happen behind the walls.
For example, a dental clinic may require substantial coordination between equipment, plumbing and electrical systems.
A restaurant can involve ventilation, mechanical, electrical and plumbing requirements that have a major impact on the build.
The right budgeting question is therefore not simply:
“How much will the renovation cost?”
It is:
“What does this property require to become the business we are planning?”
4. How Much Contingency Should a Commercial Project Have?
There is no universal contingency percentage that is correct for every commercial construction project.
The appropriate amount depends on the project's risk.
A new building with highly developed drawings presents different uncertainties from renovating an older commercial property where existing conditions may be concealed.
Factors that can influence contingency include:
- Design completeness
- Existing building conditions
- Project complexity
- Scope certainty
- Level of site investigation
- Potential unknown conditions
Contingency should provide flexibility for legitimate project uncertainty.
It should not be used as a substitute for incomplete estimating.
5. What Permits Are Needed for Commercial Construction in Calgary?
Permit requirements depend on the property, scope of work and how the completed space will be used.
The City of Calgary has commercial permitting processes covering new buildings and additions as well as alterations to existing buildings. Depending on the work, commercial alterations can include interior or exterior renovations, structural changes, interior demolition and leasehold improvements.
Electrical, plumbing, gas or mechanical work may also require separate trade permits.
This creates an important distinction:
Permitting is affected not only by what you are changing physically, but also by what you intend to do with the space.
A property being converted to a different business use may therefore need to be evaluated differently from a straightforward cosmetic renovation.
Permit requirements should be investigated during planning—not after construction has been scheduled.
6. How Long Does Commercial Construction Take?
There is no reliable one-size-fits-all timeline for commercial construction.
The duration depends on the type and complexity of the project as well as how prepared it is before work begins.
The schedule can be affected by:
- Design completion
- Permits and approvals
- Existing site conditions
- Project size
- Material availability
- Specialized equipment
- Trade sequencing
- Inspections
- Scope changes
- Owner decisions
A basic office renovation, restaurant build-out, medical clinic and ground-up commercial development should not be expected to have the same timeline.
Instead of asking only:
“How fast can construction start?”
ask:
“What needs to happen before construction can start properly?”
Starting earlier is not necessarily finishing earlier when major decisions remain unresolved.
7. When Should You Bring a Commercial Contractor Into the Project?
For many projects, contractor involvement during planning can help connect the design and business objectives with construction cost, sequencing and practicality.
Early contractor involvement can help evaluate:
- Constructability
- Preliminary costs
- Site logistics
- Material availability
- Construction sequencing
- Scheduling
- Potential challenges
- Alternative construction approaches
This does not replace the architect, engineer or other consultants.
Each has a different role.
The value comes from getting the people responsible for designing, approving and constructing the project aligned before major decisions become expensive to change.
How Do You Compare Commercial Construction Quotes?
Do not compare commercial construction proposals by the final price alone. Compare what each price actually includes.
Imagine receiving:
Proposal A — $480,000
Proposal B — $520,000
Proposal A appears to be $40,000 cheaper.
But is it?
One proposal may exclude work included in the other.
Allowances may be different.
Material assumptions may be different.
One contractor may have identified a requirement another contractor has not included.
Before comparing the total price, compare:
- Scope
- Inclusions
- Exclusions
- Allowances
- Material assumptions
- Responsibilities
- Change-order process
- Schedule assumptions
The lowest quote and the lowest final project cost are not necessarily the same thing.
What Causes Commercial Construction Projects to Go Over Budget?
Projects commonly exceed their original budgets when the scope, assumptions or existing conditions change.
Typical causes include:
- Owner-requested changes
- Incomplete design information
- Unexpected existing conditions
- Material changes
- Additional required work
- Coordination problems
- Delayed decisions
- Incorrect assumptions
- Not every cost change can be prevented.
The goal of good planning is to separate genuinely unforeseen conditions from problems that could reasonably have been discovered earlier.
What Causes Commercial Construction Delays?
A delay usually occurs when something required for the next stage of construction is not ready when expected.
For example:
- An inspection can affect the work that follows it.
- Equipment installation can depend on delivery.
- Construction can depend on approved drawings.
- Finishes can depend on preceding trade work.
- A useful project schedule therefore needs to show more than dates.
It needs to understand dependencies.
This is also why late design changes can have effects beyond the individual item being changed. A single decision can affect procurement, trade scheduling and subsequent work.
What Should You Ask a Commercial Contractor Before Hiring Them?
Before selecting a contractor, ask:
Have you completed projects similar to mine?
Relevant experience matters, particularly for specialized commercial spaces.
Who will manage my project?
Know who will be responsible for day-to-day coordination.
What exactly is included in the proposal?
Ask for clarity around scope, allowances, assumptions and exclusions.
How are changes approved?
There should be a clear process for documenting and approving changes.
How will the schedule be communicated?
Understand how progress, dependencies and delays will be reported.
How will unexpected conditions be handled?
Know the process before a problem appears.
A strong proposal should help an owner understand not only what the project costs, but what they are receiving for that cost.
A 60-Second Commercial Construction Readiness Check
Before construction begins, you should be able to answer:
☐ What exactly are we building?
☐ Can this property support the intended business use?
☐ What is included in the construction scope?
☐ What is our realistic overall budget?
☐ Are the drawings ready for the next stage?
☐ What permits and approvals may be required?
☐ Are there long-lead materials or equipment?
☐ Who is responsible for major decisions?
☐ How will project changes be approved?
☐ What could affect the schedule?
☐ Have existing conditions been investigated?
☐ What contingency has been considered?
If several answers are still unclear, more pre-construction planning may be valuable before work begins.
Frequently Asked Questions
What is the first step in a commercial construction project?
Start by defining the intended use, business objectives, preliminary scope, property requirements and budget. These decisions guide the design, permitting and construction process.
Should I talk to a contractor before signing a commercial lease?
For a property requiring substantial renovation or specialized building systems, early professional input can help identify whether the location can practically support the proposed business.
Does every commercial renovation in Calgary need a building permit?
No. Permit requirements depend on the proposed work and use of the property. Cosmetic work can be treated differently from construction, changes to building systems or changes affecting the use or occupancy of the space.
Should I choose the lowest commercial construction quote?
Not based on price alone. Compare scope, inclusions, exclusions, allowances, assumptions and responsibilities before determining whether two quotes actually represent equivalent work.
What's the biggest mistake to avoid before construction starts?
Starting construction before the scope, property requirements, design, budget and major approvals are sufficiently understood.
Start With the Project, Not the Construction
A commercial construction project should not begin with the question:
“When can we start building?”
It should begin with:
“What needs to be solved before we start building?”
The property needs to work for the business.
The design needs to work with the building.
The budget needs to reflect the actual scope.
The schedule needs to reflect real dependencies.
And the people responsible for designing and constructing the project need to understand the same objective.
The Make Group works with business owners, property owners and project teams on commercial construction, tenant improvements, renovations and specialized commercial spaces in Calgary.
The objective of early planning is simple:
Solve as much as possible on paper before you have to solve it on site.
