What is the nature of a Supplemental Instruction?

A Supplemental Instruction is typically a type of communication issued by the architect or designer to provide additional information or clarification on the project. This instruction does not lead to any changes in the overall contract time or the contract sum, meaning that it is intended solely to guide the contractor in the proper execution of their work without altering the existing agreements made in the contract.

This type of instruction serves to address ambiguities or enhance the understanding of the construction documents rather than initiate formal amendments, which would require renegotiation of the terms or financial implications outlined in the original contract. Therefore, it is categorized as an informal communication that maintains the integrity of the existing contract, enabling the project to move forward effectively while ensuring compliance with design intent and project specifications.
