CSI distinguishes between “project record documents” (kept during construction) and record drawings or as-built drawings (often prepared later by the A/E using the contractor’s markups).
In CSI’s terminology (paraphrased from the Construction Specifications Practice Guide and CDT study materials):
Project record documents consist of the marked-up drawings, specifications, addenda, change orders, and shop drawings kept current during construction, indicating actual conditions and changes in the work.
These record documents are a responsibility of the contractor, who must maintain them on the job site and update them as work progresses.
At project closeout, the contractor turns the updated record documents over to the owner (often via the A/E). The A/E may then prepare record drawings based on those markups, if required by the contract.
Therefore, the entity that maintains project record documents during construction is the Contractor, making Option B correct.
Why the other options are not correct:
A. Architect/engineer (A/E) – The A/E reviews the work and may use the contractor’s record documents to prepare record drawings, but does not maintain the working set of record documents during construction.
C. Owner – The owner ultimately receives and keeps the record documents at the end of the project but does not maintain them as the work progresses.
D. Owner or A/E – This option is inconsistent with CSI’s defined responsibility: maintenance of project record documents is specifically assigned to the contractor in standard specifications and conditions of the contract.
