This applied course introduces the fundamentals of mechanical construction drawings used in building projects. Participants learn to navigate drawing sets, understand conventions, and interpret plans, elevations, sections, details, symbols, schedules, specifications, and notes.

With a focus on HVAC, plumbing, drainage, and fire protection systems, learners develop practical skills through drawing reviews, exercises, quizzes, and a final applied examination. Designed for construction professionals, estimators, site staff, tradespeople, project coordinators, and managers who need to confidently interpret mechanical drawings for construction and coordination.

Learning Outcomes:

Upon successful completion, participants will be able to:

• Interpret mechanical design and working drawings.
• Identify HVAC, plumbing, drainage, and fire protection systems.
• Understand mechanical symbols, abbreviations, legends, schedules, and specifications.
• Locate and cross-reference information within drawing sets.
• Interpret plans, elevations, sections, and details in relation to 3D systems.
• Apply drawing-reading skills to practical construction and coordination tasks.
