Construction Timeline Guide: How Long Each Phase Takes and What to Expect

When you’re planning a construction project — whether it’s a commercial development, multi-unit residential building, or custom facility — understanding the full timeline can help you make better decisions, reduce stress, and stay prepared. At FCC Builders Canada, we believe that transparency is key. That’s why we’ve put together this straightforward guide to help you understand the major phases of a typical construction project and how long each one may take.

1. Pre-Construction Planning (3 to 6 months)

Every successful build starts long before equipment arrives on site. The pre-construction phase is where your project truly begins to take shape. This stage includes reviewing the site, conducting environmental and geotechnical assessments, preparing surveys, and beginning the design process with architects and engineers.

During this time, your team will also handle zoning and by-law reviews, submit applications for permits, and develop initial budgets and construction timelines. For many clients, this phase also includes selecting the right builder, finalizing project financing, and conducting value engineering to align the design with cost expectations. In Ontario, this phase can take longer if your project requires site plan approval, rezoning, or conservation authority clearance.

2. Site Preparation and Excavation (1 to 2 months)

Once the necessary permits are in place, site work can begin. This stage involves clearing the land, grading it, and excavating for foundations or underground infrastructure. Crews may install temporary fencing, access roads, and erosion control systems to maintain site safety and environmental compliance.

If the land requires additional work — such as blasting rock, remediating soil, or coordinating new utility connections — this phase may extend beyond the typical one-to-two-month timeframe. Ontario’s weather can also impact this phase, especially if work begins during the winter or during heavy spring rains.

3. Foundation and Structural Framing (2 to 4 months)

With the site ready, the team moves on to building the foundation. Depending on the project, this may include pouring concrete footings, walls, or slabs. Once the foundation cures, structural framing begins. This could involve steel beams, wood framing, or concrete block, depending on the design.

This is one of the most exciting parts of the project, as the shape and size of the building finally become visible. The speed of this phase depends on the size of the structure, availability of materials, and labour scheduling. Weather, again, plays a role — especially if concrete pours or rooftop work are scheduled during extreme conditions.

4. Building Envelope and Rough-Ins (2 to 5 months)

Once the framing is complete, the building is “closed in.” This includes installing roofing, exterior cladding, windows, and doors. With the structure sealed, interior work can begin safely. The trades then rough-in key systems like HVAC, electrical, plumbing, and fire protection.

This is one of the busiest stages of construction, with multiple trades working simultaneously. Project management and trade coordination are especially important during this phase to keep the schedule on track and avoid conflicts between teams.

5. Interior Finishes and Site Work (2 to 4 months)

With the rough-ins complete and inspected, the team moves to finishes. This includes insulation, drywall, taping, painting, flooring, tiling, cabinetry, fixtures, and trim. At the same time, exterior work like curbs, sidewalks, landscaping, and parking areas is typically completed. Depending on the size and complexity of the building — especially for hotels, retail plazas, or restaurants — this stage may also involve installing furniture, commercial equipment, or signage. Quality control becomes a top priority here, as the finishing touches define the final appearance and functionality of the space.

6. Final Inspections and Occupancy (1 to 2 months)

Before you can open your doors, the building must pass a series of final inspections. These may include fire, structural, plumbing, electrical, HVAC, and building code compliance checks. Once everything is approved, the municipality will issue an occupancy permit.

During this time, the builder will walk through the building with the owner to create a deficiency list and address any outstanding issues. Turnover documents, warranties, manuals, and maintenance instructions are typically handed over at this stage as well.

What Can Affect Your Timeline?

While the above timeframes are typical, it’s important to remember that no two projects are the same. Factors that can influence your construction schedule include:

• Delays in municipal permits or zoning approvals

• Design revisions or late material selections

• Supply chain disruptions or custom product lead times

• Weather conditions, especially in winter

• Changes requested during construction (also known as change orders)

At FCC Builders Canada, we plan for these variables from day one. Our experienced project managers use detailed construction schedules, clear communication, and early coordination with trades to minimize delays and deliver your project on time.
