Where a well and site disposal of wastewater are required, ensure adequate separation between them. Consult Chapters 6 and 28 for more information on site planning.
Protection and Care of Materials on the Building Site Materials stored on site must be protected. Failure to do so can result in waste or construction defects. When possible, material should be delivered to the site just before it is used. The moisture content of framing lumber at the time of installation must not exceed 19 per cent. S-DRY lumber meets the 19 per cent moisture limit but can re-absorb water if it is left unprotected on the site. Store wood products in a dry, well-drained area. Lumber and sheathing materials should be stored 200 to 250 mm (8 to 10 in.) above the ground on flat supports. Keep the products covered until ready for use. Vertical wood members exposed to the weather during construction can dry relatively quickly after wetting but horizontal components need more time to dry. After rain, wood members must be allowed to air dry before being enclosed. Allow sufficient time and ventilation for the materials inside wall cavities to dry to an acceptable level before installing the vapour barrier. Asphalt shingles should be stored so that the bundles can lie flat without bending. Using curved or buckled shingles will result in an unattractive roof and a shortened service life. If windows and doors are delivered before they can be installed, they should be protected from weather and damage. Batt insulation and drywall are very susceptible to water damage and must be protected.
Hardwood flooring, interior trim and millwork should not be stored in the house until the building moisture resulting from concrete curing, drywall finishing and any rain that was admitted during construction has had time to dissipate. Distribute heavy materials stored on framing members, such as gypsum wallboard or asphalt shingles, to avoid overloading.
Excavation, Footings and Foundation A good foundation is essential for structural support and controlling ground water and forms part of the soil-gas control system (see Chapter 7 for more information).
Determine the water conditions on the property, how water will be drained away from the foundation, and whether basement dampproofing will be adequate for the water conditions. Establish the foundation wall thickness based on the backfill height, the number of storeys to be supported and the height of the wall. Consider the space required for beams, ductwork and plumbing in determining the basement ceiling height. Consider using a higher basement ceiling height if it is likely the basement will be finished. Determine whether the basement insulation will be on the inside or outside of the foundation walls. Plan for the foundation to support a masonry chimney, if there will be one. Plan for pipes and services that pass through the foundation. Provide the required pipe stub connection for future radon removal, should radon prove to be a problem after the house is occupied. Determine the location of anchor bolts in the top of the foundation wall to secure the framing to the foundation.
