Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Construction sites are one of the most hazardous work environments in Canada. Fall protection, scaffold safety, struck-by and caught-in hazards are among the leading causes of fatalities. This section ensures you can identify hazards, apply controls, and know the regulations that protect workers.
Exposed aggregate: surface paste removed to reveal stones; decorative, non-slip. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Building codes, fire codes, and workplace regulations define the minimum standards that protect occupants and workers. These aren't guidelines — they're legal requirements. Knowing your applicable codes means fewer failed inspections, less rework, and a professional reputation that lasts.
Bull float: large, pushes aggregate down, smooths; darby: smaller, for edges/corners. Knowing what each component does — not just what it is — helps you diagnose failures, specify replacements, and explain your work to inspectors and clients.
Structural calculations, material quantities, load calculations, and slope determinations are all part of journeyperson knowledge. These questions test your ability to move between units, apply geometric principles, and size materials correctly for the application.
W/C: 0.40 = strong but stiff, 0.60 = workable but weaker; balance needed. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
Curing: moist/warm conditions allow hydration; wet burlap, plastic, mist 7-28 days typical. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Construction materials have specific strengths, limitations, and proper applications. Choosing the wrong adhesive, fastener, or structural member isn't just a quality issue — it can be a structural failure waiting to happen. Know your materials.
Slump: settlement of concrete after rodding; workability indicator. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Admixtures: air (freeze/thaw), water-reducer (improve strength), retarder (hot weather), accelerator (fast set). On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Trowel: 3-4 passes; early passes smooth, later passes (blade up) close surface, harden finish. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Joint spacing: slabs = length/2 or width/2 (max); beams = d × 2 (approximately). Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
slabs = length/2 or width/2 (max)
Cold cure: heated materials, insulation preserve heat, accelerator speeds strength gain before freeze. Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Quality construction depends on proper sequence, technique, and workmanship standards. Whether it's concrete curing, wood framing, or tile installation — how you do it determines how long it lasts. These questions test the procedural knowledge that defines trade-level competency.
Timing: early (too soft), late (cracks already present); sweet spot ~18 hours typical. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
