What Division 01 covers
Each technical section tells you what to build. Division 01 tells you how the job runs. Its sections apply to every trade unless a technical section says otherwise. Most technical sections open with a line that makes Division 01 part of that section.
- Summary of work, phasing and owner occupancy.
- Allowances, unit prices and alternates.
- Substitution procedures.
- Payment procedures and the schedule of values.
- Submittal procedures.
- Quality requirements, testing and inspection.
- Temporary facilities, protection and cleaning.
- Closeout: record documents, manuals, training and warranties.
Why it costs money
Division 01 items rarely show up in a trade section, but they land on the trade. A phased job can mean two mobilizations. Work in an occupied school can mean night or weekend hours. A closeout section can require printed manuals, record drawings and a training session.
What to look for as a subcontractor
- Work hours and site access limits.
- Phasing and the number of trips to the site.
- The substitution process and its deadline.
- Submittal count, format and review time.
- Who pays for testing and for failed tests.
- Daily cleanup and final cleaning duties.
- Closeout documents and attic stock.
Division 01 and your subcontract
A subcontract usually binds you to the prime contract documents. That includes Division 01. Reading it late does not remove the requirement. Read it during the bid, and price what applies to your work.
On a large job Division 01 can run past a hundred pages. Start with the sections in the list above. Skim the rest for anything that names your trade.
Check the addenda too. An addendum can change a Division 01 section as easily as a trade section. A new phasing plan or new work hours changes your labor.
