Building Layout
Framing
The first construction step is to position the building on the property. The services of a land surveyor may be required to establish the distances from the foundation to property lines, locate the municipal services and establish the layout and the depth of the excavation.
About two weeks is needed to complete the framing and install roofing to provide weather protection during subsequent stages of construction. Built-in bathtubs and shower enclosures are usually installed at this time. Framing dimensions must be appropriate for these components. Once installed, they should be protected from damage until the house is finished. Chimney installation and the building of stairs or the installation of pre-manufactured stairs is usually considered part of the framing stage. Deck framing is usually performed while the landscaping is being done.
Excavation and Footings Excavation for the foundations may proceed once the building layout has been completed. This can often be completed in one day depending on the type of equipment used and site conditions. Another few days are needed to trench for and install services, form and place footings, remove footing formwork and lay out the foundation walls and columns. Placement of the granular layer and basement floor slab usually occurs later when the basement plumbing rough-in is completed. Storing topsoil and good quality excavated material suitable for backfilling can reduce the amount of imported fill and topsoil for landscaping.
Foundations, Drainage and Backfill Foundations can be placed in one day by a skilled contractor and require at least one week for concrete to cure before formwork can be removed. Dampproofing, foundation drainage systems and backfill requires another day or two. Additional measures for foundation drainage such as waterproofing, sump pumps, ditching or dry wells may be required. Backfilling should not begin before the first floor framing has been anchored to the foundation and the first floor sub-floor has been installed because the floor framing helps to resist the soil pressure. Contact your building official to inspect the footings and foundation and municipal service connections.
Doors and Windows Installing doors and windows requires a few days to complete and includes the installation of sub-sill membrane, flashing, locks and other hardware. Jamb extensions are usually part of the finishing carpentry work, and exterior trim is usually installed by the trade installing the exterior finishes. The air sealing of gaps around window and door openings is usually performed as part of the insulation, vapour barrier and air barrier system work. Contact your building official to inspect the completed house framing, including windows, doors and skylights.
Plumbing, Heating, Electrical and Ventilation Rough-in The water-heating piping is installed. Plumbing is installed to connect from the water service to the water heater and fixtures. The electrical panel is installed. Electrical wiring, smoke and carbon monoxide alarms, telephone and computer lines, and cable TV are roughed in. The furnace ductwork or piping are installed, along with ductwork for exhaust fans and mechanical ventilation equipment such as heat recovery ventilators (HRVs). This work takes about two
