What is the purpose of issuing supplementary instructions?

The purpose of issuing supplementary instructions is to allow prompt changes within reasonable time frames during the course of a project. These instructions are typically used to clarify or modify aspects of the contract documents without going through the formal contract change order process, which can be time-consuming. By using supplementary instructions, architects and project managers can address issues that arise on-site, provide necessary information, or make adjustments to the project as it progresses, ensuring that work can continue smoothly and efficiently. This adaptability is crucial in the construction industry, where unforeseen circumstances often require immediate attention to keep a project on schedule and within budget.

The other options do not capture the specific function of supplementary instructions in the context of project management and construction processes. General updates and regular communication might occur through other means and do not necessarily have the same urgency or specific purpose of addressing immediate changes in a project. Rejecting bids is a different process altogether and does not relate to the application of supplementary instructions in managing ongoing work.
