Question: A tower crane requires tie-ins to an adjacent building. What is the most critical factor to consider when designing and installing these tie-ins?
Answer options: ✅ The structural integrity and capacity of the building connection points to withstand crane loads.
- The aesthetic appearance of the tie-ins to match the building's facade.
- The cost of the tie-in materials.
- The convenience of access for maintenance personnel.
Correct answer: The structural integrity and capacity of the building connection points to withstand crane loads.
Explanation: The paramount consideration for tower crane tie-ins is the structural integrity and load-bearing capacity of the building's connection points. Tie-ins transfer significant forces (wind, operating, erection loads) from the crane to the building, and inadequate building connections can lead to catastrophic failure, as outlined in CSA Z248 and OHS provincial regulations.
