Which of the following activities is included in the definition of 'construct'?

The definition of 'construct' in the context of building codes encompasses a broad range of activities related to the erection and alteration of buildings. This includes not only the initial construction of new structures but also various modifications, improvements, and repairs that may be necessary for existing buildings.

Choosing the correct answer highlights the breadth of the construction process as defined by the building code. It recognizes that construction is not limited to new placements of materials but also involves significant alterations, renovations, refurbishments, and any activity that affects the building's structure or function. This inclusive understanding aligns with the comprehensive nature of the building code, which aims to ensure safety, sustainability, and compliance across all facets of built environments.

The other options represent narrower interpretations that overlook the full scope of activities typically covered under 'construct', missing critical aspects of renovation and alteration that are essential to adhering to the Ontario Building Code.
