MEP Coordination & Integration
Rough-in Sequencing for MEP Trades
The CSLB exam expects you to understand the logical progression of construction tasks. For MEP, remember the general rule: systems requiring larger, more rigid pathways (like plumbing drains and large HVAC ducts) often go first, followed by more flexible systems (like electrical wiring). Pay attention to questions about avoiding conflicts and ensuring code compliance before covering up.

MEP Coordination & Integration
Fire Blocking & Penetration Requirements
The CSLB exam frequently tests on the general requirements for fire blocking in concealed spaces and the maintenance of fire ratings at penetrations. Keywords to spot include 'concealed spaces,' 'fire-rated assembly,' 'penetration,' and 'firestop system.' Remember that fire blocking is generally required horizontally and vertically at specific intervals (e.g., every 10 feet) in wall cavities and at floor/ceiling lines.
MEP Coordination & Integration
Fire Blocking & Penetration Requirements
Using non-approved materials for fire blocking or firestopping, such as regular insulation or expanding foam not rated for fire.

Understanding Basic MEP System Components
The CSLB exam often tests your understanding of basic code requirements for MEP systems, such as minimum clearances for electrical panels (e.g., 30 inches wide or the width of the equipment, and 36 inches deep) and proper venting for plumbing fixtures. Memorize these specific numbers and the general principles behind them.
