Which of the following items is NOT typically included in design details?

In the context of refractory design details, the items typically included focus on the technical and operational aspects necessary for the installation and performance of the refractory system.

Surface preparation procedures, welding procedures, and anchor material and geometry all fall within the scope of these design details. They provide essential guidelines on how the surface should be prepared for optimal adhesion, how any necessary welding will be managed, and what types of anchors will be used to secure the refractory materials correctly. These components are crucial for ensuring that the refractory materials perform as intended and can withstand the conditions they are exposed to.

On the other hand, while a proposed budget and timelines are essential elements for project planning and execution, they do not directly influence the technical specifications or operational details of the refractory design. Instead, they are more concerned with the financial and scheduling considerations of the project. Thus, they are typically managed separately from the technical design documents. This distinction helps clarify why the proposed budget and timelines are not considered part of the design details for refractories.
