Unplanned demob-remob costs 10-25% of trade value. This calculator quantifies the exposure.

Re-mob fee

Standby time cost

$12,600

How the math works

Cost = re-mob fee (60% of mob) + standby time (up to 1 week at crew rate).

Each unplanned demob-remob cycle costs 5-10% of subcontract. Minimizing cycles = preserving budget. Locked sequence and pre-approved changes are the best defense.

Frequently Asked Questions

Mob/demob structure?

Typical subcontract has 5-10% mobilization fee at start and 2-5% demobilization fee at end. Covers crew movement, tool setup, trailer, logistics, admin. Duplicated when work interrupted.

Common causes?

Schedule delays pushing sub off site. Design changes requiring work pause. Weather hold. Change order approval delay. Material availability. Each extra mob-demob cycle is extra cost.

Avoiding?

Commit to sequence before each sub's start date. Pre-approved change orders to avoid mid-work pauses. Material delivery lock-in. Clear handoff protocol between trades.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
