ARE PPD Exam Tips - How to Pass Project Planning & Design

PPD Exam Overview

Project Planning & Design is widely considered the hardest ARE division because of its enormous scope. It covers structural systems, building envelope, HVAC, plumbing, electrical, fire protection, accessibility, and egress - all in one exam with approximately 75 questions and a 3 hour 20 minute time limit.

What to Study First

1. Structural Systems - Know the characteristics, spans, and applications of steel, concrete, wood, and masonry systems. This is the most heavily tested topic.
2. Building Envelope - Vapor barriers, air barriers, thermal performance, moisture management, and wall assembly design by climate zone.
3. Fire Protection - Fire-resistance ratings, fire separation types, sprinkler systems, and how they affect height/area calculations.
4. Egress - Occupant load, exit width, travel distance, common path, dead ends, exit separation.
5. MEP Systems - HVAC system types, plumbing basics, electrical distribution, and lighting.

Systems Selection Questions

PPD's hardest questions ask you to select the best system for a scenario. Use this framework:

1. What are the constraints? (Span, height, fire rating, budget, site conditions)
2. What are the priorities? (Cost, speed, flexibility, aesthetics, sustainability)
3. Which system fits best? (Eliminate systems that can't meet the constraints, then rank by priorities)

Never pick a system based on one factor alone. The ARE tests multi-factor decision-making.

The Envelope Section

Building envelope questions are second only to structural in frequency. Know these cold:

• Vapor barrier placement by climate zone (warm side of assembly)
• Air barrier continuity requirements
• Drainage plane and flashing integration
• Thermal bridging at structural penetrations
• R-value vs. U-factor (U = 1/R for total assembly)

Time Strategy for PPD

PPD questions often require more thought than other divisions because they involve system selection and integration. Budget your time accordingly:

• Quick concept questions: 1-2 minutes
• System selection questions: 3-4 minutes
• Calculation questions: 4-5 minutes
• Leave at least 30 minutes for review
