Design and decisions come before the crew
The most reliable schedules begin with a defined footprint, material, finish, access plan and written scope. Unresolved selections can delay procurement or change the crew plan.
Construction duration depends on scope
Demolition, access, weather, excavation, steps, borders and finish complexity all affect field time. Ask for a sequence of work rather than a guaranteed date that ignores weather.
Installation is not the end of the timeline
Concrete needs curing time and some finishes require sealing or later maintenance. Your handoff should clearly state when people, furniture and vehicles can return.
The final recommendation should come from the actual property, written scope and contractor—not a generic article.
