The architect has the sole responsibility for ordering what?

The correct answer centers on the authority of the architect in relation to minor changes in work during a project. An architect often has the responsibility for overseeing the construction process and ensuring that work is completed to the specifications laid out in the designs. This includes the authority to manage adjustments that are necessary to improve the project or address unforeseen circumstances, particularly when these adjustments are minor in nature.

Minor changes typically involve alterations that do not significantly affect the project’s scope, timeline, or budget. The architect can quickly assess and make decisions on these smaller modifications to maintain progress and coherence with the overall design intent. Major changes in design, on the other hand, typically require extensive consideration, potentially necessitating involvement from other parties including project stakeholders or clients. Similarly, issues pertaining to additional manpower and material purchases often require input from project managers or contractors, as these decisions can have significant implications on the project’s budget and workforce.

This delineation of responsibility underscores the architect's role as both a designer and a manager in enabling the project to proceed smoothly while maintaining adherence to the initial design concepts.
