If you have committed to a date, tell JAMES the constraint rather than the wish. A schedule built on optimism breaks in week one.
Week one: installs A and B in parallel, one engineer each. Four days each, one day buffer.
Week two: both on install C. Three days together, two days buffer.

Call them today and confirm the date in writing. If they cannot commit, swap C to week one and pull B back.
Want me to draft that confirmation?
It found the job most likely to slip and told you to act before it did.
