 9.15.4.10. Interior Masonry Walls

This Article points to the requirements in NBC Section 9.20. for interior masonry walls acting as foundation# walls so that they are constructed to have adequate strength to support anticipated loads. 

The minimum #width for an interior loadbearing masonry# wall depends on the spacing of its lateral support. Such walls must be laterally supported by floor or roof construction, or by intersecting masonry walls or #buttresses. The maximum spacing of such supports can be no greater than 20 times the wall thickness, as illustrated in Figure 9.15.-18 (NBC Article 9.20.10.1.).

Important definition: Secondary Suite

Secondary suite means a self-contained dwelling unit located in a building or portion of a building of only residential occupancy that contains only one other dwelling unit and common spaces, and where both dwelling units constitute a single real estate entity.

Guidelines for Effectively Engaging a Building Code Consultant

 Guidelines for Effectively Engaging a Building Code Consultant

When contemplating the engagement of Building Code Consultants, it is crucial to examine their LinkedIn profiles to verify that they possess the necessary qualifications and experience, unless we are prepared to provide them training through our projects.

Consider the following scenarios:

If we were to hire a #physician to safeguard our health, but this "physician" has never attended medical school or treated a patient in a #clinical setting, the consequences could be dire.

If we were to engage a #structural engineer to design a #skyscraper, yet this "structural engineer" lacks knowledge of structural mechanics and has no prior experience in an architectural firm, the building could potentially collapse.

If we were to select a building code consultant to aid in our building permit application, but this "consultant" has never enforced Building Code within a municipality, our application process may become increasingly complicated.

Many challenges we encounter today may stem from our initial hiring decisions. #hiring #design #training #experience #buildingcodeconsultant #linkedin.

Converting a single-family house into a daycare facility is a complex undertaking that cannot be accomplished solely by an architectural designer. It requires the involvement of an architect, a structural engineer, a mechanical engineer, and an electrical engineer. Crucially, the expertise of a building code consultant, well-versed in the relevant codes, is invaluable for ensuring compliance and achieving cost savings. In a recent project, I successfully saved the building owner approximately $50,000 by retaining the existing structure and providing appropriate fire separations.

9.15.4.9. Crack Control Joints

 9.15.4.9. Crack Control Joints

This Article sets minimum distances for the location of joints in foundation walls designed to reduce #cracks so that the entry of soil drainage #water and #moisture can be minimized.

Both cast-in-place #concrete and concrete block shrink over time as a result of curing and drying. To control #shrinkage cracking, concrete block masonry units are either steam cured or autoclaved by the producer, and are required to satisfy permissible limits on linear drying shrinkage. Even so, some shrinkage may be expected for both cast-in-place concrete and concrete masonry #foundation walls.

Crack control joints may be necessary to accommodate this shrinkage. These joints are designed to move apart slightly as the wall shrinks, while maintaining a watertight surface. These are required to be installed not more than 15 m (45 ft.) apart when the foundation walls are longer than 25 m (75 ft.). Figure 9.15.-17 illustrates the requirements for crack control joints in foundations and two approaches for sealing the joints.

Where possible, crack control joints should be placed adjacent to a #window opening, where the concentration of tensile stresses encourages shrinkage cracks to occur.

 9.15.4.7. Reduction in Thickness

1) Where the top of a foundation wall is reduced in #thickness to permit the

installation of floor #joists, the reduced section shall be not more than 350 mm high and not less than 90 mm thick.

2) Where the top of a #foundation wall is reduced in thickness to permit the

installation of a masonry exterior facing, the reduced section shall be

a) not less than 90 mm thick, and

b) tied to the facing material with metal ties conforming to Sentence 9.20.9.4.(3) spaced not more than

i) 200 mm o.c. vertically, and

ii) 900 mm o.c. horizontally.

3) The space between wall and facing described in Sentence (2) shall be filled

with #mortar.

How to Find a Good Building Code Consultant?

 How to Find a Good Building Code Consultant?

For those seeking a reliable Building Code Consultant, consider this golden standard: 3 years in building design at an architectural firm combined with 8 years as a Building Code Engineer in a Municipality. This unique blend of experience qualifies an individual for the role effectively.

The 3 years spent in an architectural firm provide a solid foundation in blueprint reading for structures ranging from simple to intricate. On the other hand, the 8 years in a Municipality offer valuable insights into Building Code enforcement. This extensive duration involves specialized training and licensing, equipping professionals with the ability to review and enforce codes for various building types proficiently.

It's crucial to note that the expertise of a Building Code Consultant significantly differs from that of Fire Engineers or Fire Code Consultants, as their focus is distinct from Building Code matters.

9.15.4.6. Extension above Ground Level

 9.15.4.6. Extension above Ground Level

This Article sets the minimum extension of foundation walls above ground level. The extension of a foundation above ground level is intended to avoid the entry of #rainwater run-off and #snow-melt over the top edge of the wall, and to protect water-sensitive materials supported on the foundation from prolonged wetting.

Foundation walls must extend a minimum of 150 mm (6 in.) above the #ground. If a #cladding is used that is adversely affected by #moisture, such as #wood or wood-based #siding, #clearance between the finished ground level and the bottom of the #cladding must be a minimum of 200 mm (8 in.) (NBC Article 9.27.2.4.). This also applies to #stucco over wood-frame construction (NBC Article 9.28.1.4.). These conditions are illustrated in Figure 9.15.-15.

Cost-saving opportunities exist for all types of projects, whether they involve new #construction or #renovations. For example, I recently achieved a 64% cost reduction on commonly used materials for an interior renovation of a #daycare facility. Additionally, I was able to reduce #costs by eliminating one layer of ⅝” Type X drywall from the ceiling to the wall in a #garage this morning. All cost savings are achieved while ensuring compliance with the Building Code.
