PDD Exam Dumps : ARE 5.0 Project Development and Documentation Exam

Division 06 (Wood, Plastics, and Composites) of the Project Manual contains detailed specifications for finish carpentry and casework materials. This aligns with ARE Objective 2.1: Evaluate project manual sections for technical accuracy.

The detail shows a metal connector fastening a vertical framing member (stud or post) to a horizontal member (likely a top plate or beam). This type of metal connector—often a hurricane tie or hold-down—is designed to anchor the vertical framing to the horizontal framing to prevent separation caused by uplift forces.

Key points:

Uplift occurs when wind loads or seismic activity try to pull the roof or upper framing away from the wall below.

The connector wraps over and around members, securing them together.

Commonly used in roof-to-wall connections to comply with wind resistance requirements in the IBC and ASCE 7.

This does not primarily resist sliding (shear) or racking (lateral deformation of a frame), nor is it designed mainly for twisting (torsion).

PDD ARE Objective Tie-in:

ARE 5.0 PDD Objective 3.2 – Evaluate and integrate structural systems with architectural elements, ensuring proper load path continuity for resisting vertical and lateral loads, including uplift forces.

Glycol-cooled air conditioning systems use a glycol-water mixture as a secondary coolant instead of plain water. Glycol has lower freezing point and better heat transfer properties in certain conditions.

Advantages include:

Longer piping runs without freezing risk, allowing the chiller or cooling unit to be located further away from the computer room, useful for flexible building layouts.

Glycol prevents freezing in cold climates or exposed pipes.

It does not inherently reduce heat exhausted or is necessarily more sustainable than water cooling.

Glycol is generally more expensive than water.

Therefore, the primary advantage is the ability to locate the cooling unit farther from the space being cooled.
