What coverage extension of the Builder's Risk Coverage Form would protect Veronica's scaffolding that was damaged during a storm?

The coverage extension that would protect Veronica's scaffolding is the one specifically referring to scaffolding, construction forms, and temporary structures. This extension is designed to cover these types of assets because they are often integral to the construction process but may not be included under standard coverage in other parts of a Builder's Risk policy. Since scaffolding is used to support construction efforts and is at risk during storms or other adverse weather conditions, this coverage ensures that such structures can be repaired or replaced after damage occurs.

The other options, while relevant to construction risks, do not specifically address scaffolding. Temporary structures could be a broader category, but it does not emphasize scaffolding specifically. Building materials focus on the physical materials used for construction, which does not include the scaffolding itself. An installation floater covers materials during the installation process but again doesn't specifically include scaffolding. Thus, the specific mention of scaffolding, construction forms, and temporary structures in the correct choice ensures comprehensive protection during the builder's risk coverage period.
