Write clear responses to contractor RFIs during construction

Help me draft responses to contractor Requests for Information (RFIs) on a construction project where my firm is the architect or engineer of record. Project and discipline: [e.g. "three-story school, structural engineer of record"] RFI text: [PASTE each RFI, with number, date received, and any attached sketches described] Relevant drawings and specification sections: [e.g. "S-201, detail 4/S-501, spec 03 30 00"] Our technical answer or decision: [WHAT WE'VE DECIDED - or "help me structure the question for the design team"] Contract response time: [e.g. "7 calendar days"] For each RFI, write a response that: - Answers the actual question in the first sentence. - References the specific sheets, details, and spec sections, and states whether the response clarifies existing documents or changes them. - Attaches or references a sketch number if a revised detail is needed (mark [SKETCH SK-XX]). - States plainly whether we believe the response changes contract sum or time, without conceding cost; if it does, directs the contractor to the change-order process. - Avoids means-and-methods direction that is the contractor's responsibility. - Avoids vague replies such as "see drawings" or "provide as required." Also return: 1. A log table: RFI number | subject | date received | date due | status | potential cost or time impact | follow-up needed. 2. Any RFI that looks like a disguised substitution request or claim setup, flagged for project manager review. 3. Patterns across the RFIs that point to a coordination gap in the documents. Do not invent dimensions, design values, or code requirements - mark them [ENGINEER TO CONFIRM]. Responses must be reviewed by the licensed professional in responsible charge.
