A large share of commercial and civic work happens on sites that cannot close. A county fleet yard that dispatches at six in the morning. A shopping center whose anchor is trading. A campus in session.
On these projects the construction sequence — the order that would be most efficient if the site were empty — is the wrong starting point. The phasing plan has to be built backwards from the occupant's operations.
What that costs, and what it buys
It usually costs a separate construction entrance, some night and weekend work, and a less efficient crane position. Those are real numbers and they belong in the estimate rather than being discovered later.
What it buys is an owner who does not lose revenue or service during construction, which is almost always worth more than the efficiency it costs. The failure mode is a contractor who prices the efficient sequence, wins on price, and then discovers the constraint in month two.
Get it into preconstruction
The phasing plan should be a preconstruction deliverable reviewed by the people who actually run the facility — not the owner's project manager, the operations staff. They know which door cannot be blocked in a way no drawing shows.
