control-circuit hunting, subcooling, safety factor, shear force, tensile strength);
A3.3 use correct terminology to identify and describe construction tools and equipment (e.g., tools: builder’s level, framing hammer, wire stripper, pliers, tri-square, trowel, pipe cutter, hand saw, reciprocating saw, masonry saw, circular saw, drill; equipment: air compressor, scaffolding, cement mixer, generator, electrical test meter);
A3.4 use correct terminology to describe types of residential and/or light commercial buildings (e.g., residential: bungalow, two-storey, townhouse, side-split; commercial: office, motel, warehouse, mercantile);
A3.5 use correct terminology to describe common engineering features of buildings (e.g., engineered floor joists, roof trusses, structural steel, fire barriers).
By the end of this course, students will:
A4.1 convert between fractions and decimals and between imperial and metric units (e.g., between feet and metres, between Fahrenheit and Celsius temperatures), using appropriate tables, charts, software, and/or online conversion tools;
A4.2 use mathematical concepts and formulas (e.g., trigonometric functions, Pythagorean theorem) to lay out construction projects;
A4.3 use the tables in Part 9 of the Ontario Building Code to determine the required sizes, spacings, and numbers of structural members (e.g., footings, concrete blocks, floor joists, wall studs, rafters, beams, columns);
A4.4 prepare detailed estimates of quantities and costs of materials for construction projects (e.g., concrete, lumber, roofing, millwork, finishes), and of labour costs for these projects;
A4.5 perform calculations related to the installa- tion of various building systems (e.g., electrical: calculate conduit fill for conductors of various sizes and types, power in two- and three-wire systems, and required conductor size and overcurrent pro- tection for various loads; plumbing: calculate flow rates, 45° and parallel offsets for piping, required size and slopes for drains; carpentry: calculate angles and rafter sizes for pitched roofs, and riser, tread, and floor-opening sizes for stairs; heating and cooling: calculate output of HVAC systems and heat gain and loss of buildings);
A4.6 demonstrate an understanding of scientific concepts related to construction technology (e.g., relationships among voltage, current, resist- ance, and power, and between wire size and cur- rent capacity; simple electron theory; methods of heat transfer).
