COSC 175 – Construction Print Reading | Exam 2 Q&A (100+ Questions) – Site Plans, Foundations, HVAC, Electrical

This document contains over 100 expertly answered and fully verified questions from Exam 2 of the COSC 175 2025/2026 course, focusing on advanced construction print reading and applied systems. The material spans essential construction components including site plans (plot plans, setbacks, benchmarks, contour lines), floor plans, foundation systems, and detailed building sections. Topics also include reinforcement techniques (rebar, welded wire fabric, slab-on-grade), types of foundation (caissons, grade beams, steel piles), and key terminology such as TOF (Top of Footing) and keyways. Additional sections cover wood framing members, concrete properties, steel joist notation (e.g., 12K3), and rebar sizing. Mechanical systems such as plumbing (rough-in, finish), HVAC (forced air, evaporative cooling), and electrical systems (NEC, panel schedules, GFCI installation) are also clearly explained. The final portion offers insights into welding standards and symbols, further enhancing technical understanding. This document is an essential study tool for students in construction management, architectural engineering, HVAC, plumbing, electrical systems, and technical drafting. It’s also highly applicable for trade apprenticeships and licensing exam preparation.
