Ballast CE Practice Help - Critical Path Schedule

11. The architect is reviewing a critical path method schedule from the contractor. The critical path is 200 calendar days with 30 days of float. Contractor plans on 5 day work week. What is the construction time?

Ballast says divide 200 calendar days by 5 working day to get about 40 weeks for construction. But if the project will take 200 calendar days wouldn't you divide by 7 for the days in a week resulting in approximately 28 weeks? 40 weeks for construction would be more than 200 calendar days. Is this just a Ballast typo or am I missing something?

Thanks!

It is probably a typo.

I'm not surprised by a Ballast typo, but that clears it up. Thanks!

Contractors do not work on the weekends typically, unless they are paid extra. 200 days = 40 weeks. The work week is 5 days.

Makes sense?
