Preconstruction is the work a contractor does before construction starts: walking the space, reading the lease and the drawings, building a budget, planning the permits and lining up the long-lead equipment. It is the cheapest part of a commercial project and the part that decides most of what it costs. Kay2 Commercial provides preconstruction services in Calgary for tenants, landlords and owners, either as a first step toward a design-build contract or as a stand-alone service.
Why preconstruction decides the budget
By the time demolition starts, most of a project's cost is fixed. The size of the unit, the business that goes in it, the layout, the equipment and the condition of the shell have all been decided. Construction can only deliver those decisions well or badly. It rarely changes what they cost.
That is why the most useful time to involve a contractor is before the big commitments: before the lease is signed, before the designer finishes the layout, and before the equipment is ordered. At that point a problem is a line on a drawing or a clause in a lease. After it, the same problem is a change order, a delay or a smaller scope.
A missing sanitary line costs a phone call to find before the lease is signed, and thousands of dollars to find during demolition.
What a preconstruction walk-through checks
A walk-through is a structured look at the space against what your business needs from it. These are the items that move commercial budgets the most:
- Electrical service: the size of the panel and the main service, and whether the utility can supply more if you need it.
- Plumbing: where the sanitary and water lines are, their size, and whether your sinks, washrooms or equipment can reach them by gravity.
- HVAC: the age and capacity of the rooftop units, and whether the landlord or the tenant is responsible for replacing them.
- Sprinklers and fire alarm: what is installed, and how many heads or devices a new ceiling or layout will need.
- Slab and structure: cracks, levels, and whether the floor can be cut for new plumbing or carry heavy equipment.
- Ceiling space: how much room there is above the ceiling for ducts, exhaust and services.
- Barrier-free access: the entrance, the washrooms and the path of travel, which a renovation may have to bring up to current code.
- Hazardous materials: in older buildings, whether a hazardous materials assessment is needed before anything is disturbed.
Reading the lease and the work letter
For a tenant, the lease is part of the construction budget. The work letter, or schedule of landlord's and tenant's work, says what the landlord delivers and what you pay for. The terms "base building", "shell" and "vanilla box" mean different things to different landlords, so the only safe reading is one done against what is physically in the unit.
The other numbers that matter are the tenant improvement allowance, the free-rent or fixturing period, and the landlord's construction criteria. A planning budget turns those into a negotiating position. If the allowance covers half the fit-out, you know before you sign, and you can ask for a larger allowance, a longer free-rent period or specific landlord's work, such as a larger electrical service or a new rooftop unit. Our tenant improvement page covers the work letter in more detail.
Planning budgets and estimates
A preconstruction budget is built in stages, and its accuracy improves as the design does.
| Stage | What it is based on | What it is good for |
|---|---|---|
| Planning budget | A walk-through, the lease and a concept or sketch | Deciding whether the space works and negotiating the lease |
| Design-stage estimate | Developing drawings and an equipment list | Choosing between options while the design can still change |
| Fixed price | Complete drawings and specifications | Signing a construction contract |
The planning budget is not a quote. Its job is to show the range and the items that drive it, so that the decisions with the biggest effect on cost are made on purpose. For typical Calgary cost ranges by project type, see the commercial construction page and the individual sector pages.
Permit strategy for Calgary projects
The permit path often decides the schedule more than the construction does. In Calgary, any alteration to a commercial interior needs a building permit. If the business use changes, for example from retail to a medical clinic or from office to a restaurant, a Change of Use development permit comes first and has its own review. Food businesses also need an Alberta Health Services plan review, and some uses need provincial licensing on top.
In preconstruction we work out which of these apply, what each one needs, and in what order. That way the design team produces what the City needs the first time, and the opening date in your business plan reflects the real approval sequence. The City publishes its permit requirements at calgary.ca.
Long-lead items and the schedule
Some equipment takes longer to arrive than the whole build takes to complete. Electrical switchgear and panels, rooftop units, kitchen exhaust hoods, walk-in coolers, storefront glazing and specialty equipment can all have lead times measured in months. Preconstruction identifies these early so they can be ordered as soon as the design allows, and so the schedule is built around their delivery dates rather than around hope.
What you get at the end of preconstruction
At the end of preconstruction you should have:
- A clear view of what the space or site can and cannot support.
- A planning budget with the cost drivers called out.
- A list of questions and requests for the landlord, if you are leasing.
- A permit plan with the approvals that apply and their order.
- A list of long-lead items and a realistic schedule to opening.
- A recommendation on how to deliver the project: design-build, general contracting or construction management.
Preconstruction questions
When should I involve a contractor in preconstruction?
Before you sign a lease or buy a building, and before the design is finished. That is when a planning budget can still change the deal and the design.
Is preconstruction the same as getting a quote?
No. A quote prices a finished set of drawings. Preconstruction comes earlier and gives you a budget range, the items that drive it and a plan for permits and schedule, so the drawings that get priced later are the right ones.
Do I need drawings before a preconstruction walk-through?
No. An address, the landlord's floor plan or a photo of it, and a description of your business are enough to start. Existing drawings help if you have them.
Can preconstruction lead into a design-build contract?
Yes. Many projects move from preconstruction straight into design-build with the same team, so the budget and the design develop together. It can also stand on its own if you plan to tender the work.
What does preconstruction cover for an existing building I own?
The same checks, with more attention on the building systems, hazardous materials in older buildings, and any code upgrades a renovation may trigger. See our commercial renovation page for more.
