What is a recovery schedule in construction?

A recovery schedule is a plan to catch up. When a progress schedule update shows the job forecasting late, the owner may require, or the contractor may offer, a recovery schedule. It changes the remaining work, not the history: added crews, extra shifts, overlapped activities, resequenced trades, or faster procurement, with the logic to prove the new finish date works.

Many contracts give the owner the right to demand one when the contractor falls behind by a set amount. Read that clause carefully, because it often says the recovery is at the contractor's cost.

What a recovery schedule includes

• The current status, with the delay measured against the baseline schedule.
• The cause of the delay, with references to any notices sent.
• The specific recovery actions and the activities they affect.
• Revised durations and logic, showing the new critical path.
• Resources: added crew sizes, shifts, equipment, and sub commitments.
• The cost of recovery and who is expected to pay it.

How it works on a real job

Say a GC on a $6 million charter school is 18 working days behind after a wet spring and a late steel delivery. The school must open in August. The owner invokes the recovery clause.

The PM and superintendent build a recovery schedule. They add a second drywall crew, split the building into two zones so finish trades can start in the east wing while the west wing is still in rough-in, and move ceiling grid ahead of some wall finishes. The electrical sub agrees to four weeks of 10-hour days. The new logic shows the school reaching substantial completion three days before the owner's move-in date, with that little float protected.

The recovery plan also gets a cost line. Extra drywall crew time, overtime premium for the electricians, and added supervision come to a figure the PM can compare against the liquidated damages the school would assess for each late day. Recovery is a business decision as well as a scheduling one.

The PM also separates the delay. The late steel was the supplier's problem, so the GC carries that recovery cost. But eight of the 18 days were weather beyond the contract's normal allowance, which is excusable delay. For that part, the GC submits the acceleration cost as a change order request and notes it on the schedule, so the owner cannot later say the GC recovered for free.

Common mistakes and disputes

1. Agreeing to recover owner-caused delay at your own cost. If the owner refuses time for an excusable delay and forces acceleration, document it as a possible constructive acceleration claim.
2. A schedule with no real resources behind it. Owners check whether subs have actually committed to the added crews.
3. Stacking trades so tightly that productivity drops and the recovery fails.
4. Overtime without accounting for its cost and fatigue. Long weeks lower output per hour.
