Knocked-down delivery costs less for transportation because ________________.

• A. Because more pieces can be loaded on the truck
• B. If the job site is close to the shop
• C. Because more wind resistance in the truck
• D. Only if the duct is not lined with insulation

Answer: (A)

Knocked-down delivery saves on transportation by packing more pieces into the same truck. When ductwork is shipped disassembled into flat, compact parts, it uses space more efficiently and often reduces weight per piece too. That means you can load more components on one trip, increasing the truck’s load factor and lowering the transportation cost per piece. Other factors like how close the job site is to the shop or wind resistance and insulation don’t explain this space-and-weight efficiency of knocked-down parts. Proximity to the shop affects total travel distance, wind resistance would typically increase costs, and insulation adds weight/volume regardless of the knocking-down method.
