The Phases of Construction

A large-scale project requires careful planning and organization. Each step is important and must follow a precise order to provide a high-quality, durable project. Read on to discover the groundwork that went into your future condo.

The Foundation

  1. Excavation and decontamination
    The digging begins: soil tests will determine if decontamination is required.

The Structure

  1. Formwork
    Formwork sections are being prepared. These are the temporary moulds into which the concrete is poured, which are then removed after drying. This element plays a major role in the construction and determines the shape of the building.
  2. Basement slab
    The first concrete slab is poured. This slab is crucial as it bears the load of the entire building. As such, it is more complex and harder to pour. The number of slabs will vary based on the number of floors below ground.
  3. Ground-floor slab (and upper storeys)
    Once this slab is laid down, construction follows a more regular pace although weather will still play a decisive role. On average, we pour one slab (i.e. one floor) per week.
  4. Roof slab
    This is the last step on the concrete side of things, and, generally, the point at which we will be able to provide a delivery date, as weather has less of an impact on the subsequent construction phases.

Building Envelope

  1. Exterior walls
    Scaffolding is set up and the exterior walls and gyplap (exterior gypsum) are erected.
  2. Window installation
    Window membranes and then windows are installed.
  3. Exterior insulation
    Urethane foam is injected on the building’s exterior envelope to increase thermal resistance and provide air and vapour barriers.
  4. Exterior masonry
    Bricks and other types of siding are laid down.


  1. Interior Finishes
    This phase is when individual units really take shape, based on the choices made by their future owners. It includes the finishing work for all spaces, both private and common (plumbing, electrical, partitions, soundproofing, gypsum, drywall joints, tiles, finish carpentry, painting, cabinets, counters, floors, etc.). This phase is like a well-choreographed dance: every step follows a predetermined sequence and each trade plays its part in the success of the overall performance. From the outside, the construction site may seem quiet, but the inside is buzzing with activity.
