Red Seal Carpenter Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

When setting up shoring for a suspended slab, the correct mathematical process is to add the height of the shore, the depth of the stringer, the depth of the joist, and the thickness of both the formply and the slab to determine the top of the pour. This is because all of these components contribute to the overall height of the slab. Option A is incorrect because it does not account for the depth of the stringer. Option B is incorrect because it does not account for the depth of the stringer and only considers the thickness of the slab. Option D is incorrect because it does not account for the depth of the stringer and only considers the thickness of the formply. Therefore, option C is the only correct answer as it considers all necessary components for determining the correct height of the slab pour.
