SECTION B — Long Questions (4 × 7 = 28 Marks)
(Shown on Page 1, after Section A)
Students must attempt any four questions.
The questions require explanation, sketches, and construction-based detailing.
Topics include:
Properties and uses of timber Classification & properties of stones used in construction
Methods of seasoning timber Requirements and types of floorings
Explaining roof coverings Classification of stairs and requirements of a good staircase
Types of doors and windows commonly used
These questions test deeper understanding of materials, construction techniques, and structural components.
SECTION C — Applied Construction Questions (Each 7 Marks)
(Page 2)
Section C contains Question 6 and Question 7, each having two alternatives (a or b).
Students must attempt one part from each question.
Q6 — Ventilators / Lintels
(Shown on Page 2)
