To reduce the subcontractor's insurance premium

Correct answer: To provide the GC coverage under the sub's policy for claims arising from the sub's work

Additional insured status extends the subcontractor's liability coverage to protect the GC against third-party claims arising out of the subcontractor's operations on the project.

Question 31: What is the structural function of anchor bolts embedded in a concrete foundation?

To connect rebar cages together during concrete pouring
To secure the sill plate (mudsill) to the foundation, resisting uplift and lateral movement (Correct answer)
To anchor the concrete forms during placement
To provide attachment points for floor joists to the foundation wall

Correct answer: To secure the sill plate (mudsill) to the foundation, resisting uplift and lateral movement

Anchor bolts are cast into the concrete foundation to mechanically fasten the wood sill plate, preventing the structure from lifting off or sliding during wind or seismic events.
