Which of the following is NOT part of crane and derrick selection and placement procedures?

The sequence of erection activity is indeed not explicitly part of the crane and derrick selection and placement procedures. These procedures primarily focus on factors that directly influence the capability and safety of the crane operation, such as the weight of the load, the type of crane being utilized, and the location of the worksite.

When selecting and placing a crane, it is essential to consider the load weight to ensure the crane can safely lift and support the load without risking failure. The type of crane is crucial as different cranes have varying capabilities, limitations, and operating environments. Knowing the location of the worksite is necessary to assess potential hazards, site access, ground conditions, and other environmental factors that may affect crane operation.

In contrast, while the sequence of erection activity is important for overall project planning and execution, it does not directly impact the selection and placement of the crane itself. Thus, this element is relevant to the construction process but falls outside the specific procedures for crane operation safety and efficacy.
