What you actually find there
Summary of work, allowances, alternates, unit prices, substitution procedures, coordination, project meetings, submittal procedures, quality requirements, temporary facilities, product storage, and closeout submittals. The exact sections vary. The role does not.
Section 01 33 00, or its successor in the project's numbering, is where submittal lead times, electronic procedures, and resubmittal rules usually sit. Trade sections then list what must be submitted, and they should point back here for how.
Division 01 and the general conditions
A201 and similar documents cover the rights and duties of owner, architect, and contractor. Division 01 tells the contractor how this project wants RFIs, submittals, schedules, and closeout formatted. If they conflict, the agreement's precedence clause decides. They should be written so they do not conflict.
Supplementary conditions modify the general conditions. They are not Division 01 either. Three places can change the same duty. Someone has to read all three before the project manual is issued.
Bidders miss Division 01 because it has no quantity
Temporary power, dumpsters, mockups, extraordinary closeout binders, and BIM coordination requirements live here and cost money. An estimate that prices only Divisions 03 through 33 will be short.
Allowances and alternates defined in Division 01 have to match the bid form. A mismatch is a bid-day dispute about what number was requested.
One procedure, many sections
Each technical section should say which items are submitted. Division 01 should say how many copies, what a deviation looks like, and how long review takes. When a trade spec shortens the review period on its own, the contractor will cite Division 01 and the designer will cite the trade spec.
Closeout requirements, including O&M manuals and record drawings, belong here and in the technical sections' closeout articles. Say which document controls the format.
Boilerplate that was not edited
Division 01 templates mention procedures the project does not use, or they omit ones it does. An unedited section that requires a trailer the site cannot hold, or a process the owner does not run, is still a specification until you change it.
Edit it against the agreement and the supplementary conditions before the book is issued. Adding project procedures by email after award is a change.
