Which of the following is NOT a factor that can hinder the erection process?

• A. Panels stack cast in the wrong order
• B. Having a crane on site
• C. Inadequate crane size
• D. Panels cast in the wrong location

Answer: (B)

This item tests what can slow down or block the tilt-up erection process versus what doesn’t. Having a crane on site is not a hindrance; it’s essential for lifting and placing panels, so it actually facilitates erection.

Factors that do hinder include misordering or misstacking panels (which disrupts the sequence and alignment and can cause rework), or casting panels in the wrong location (which creates crane access issues and extra handling, again slowing progress). An inadequate crane size also hinders by not providing the needed lift capacity or reach to place panels accurately and safely.

So, the presence of a crane on site is the one element that does not hinder—it's a requirement that enables the erection to proceed efficiently.
