How a construction schedule should be reported to an owner

Weekly, with the critical path marked, the float shown and the slips explained. If your updates do not look like this, ask why.

Most owners receive a schedule at the start of a project and a surprise near the end. Here is what the reporting in between should look like.

Weekly, not monthly

A monthly update hides a three-week slip until it is four. Weekly updates catch it at one.

The critical path, marked

The owner should know which activities drive the completion date this week. If the critical path moved, the update should say where and why.

Float, shown honestly

Float is schedule margin. A contractor who hides it is keeping it for themselves; a contractor who shows it is telling the owner how much room there is for decisions. Ask for it.

Slips explained with recovery

A slip is a fact. The question is what recovers it: resequencing, overtime, a second crew, or accepting a later date. The update should say which, and what it costs.

Owner decisions, dated

Half of schedule slips are decisions the owner has not made yet. The update should list the open decisions and the date each one becomes critical.

Our owners get this every Friday. It takes the PM an hour and it is the reason our completion dates hold.
