Steel Plant Contractor Management Case Study: Recover $1.1M Using CMMS Work Orders

Contractor spend is one of the hardest numbers to trust in a steel plant. Timesheets get filled out on paper, scope changes happen verbally on the shop floor, and by the time an invoice lands on a desk, nobody can say for certain whether the hours billed match the work actually done. This case study looks at how a steel plant used OxMaint CMMS to turn every contractor job into a tracked digital work order, and how that single change recovered $1.1M in overrun costs in twelve months.

The Challenge

Contractor jobs were approved verbally and tracked on paper timesheets, so hours billed rarely matched hours worked. Scope changes on the floor never made it back into the original work order, overtime went unquestioned, and equipment sat idle on the clock. Every invoice audit turned into a dispute nobody had the records to win.

Contractor Management Before And After

Area	Before	After
Work approval	Verbal sign-off on the floor, no linked record	Digital work order created and approved before work starts
Labor hours	Paper timesheets reconciled weeks later, if at all	Logged against the work order in real time on mobile
Scope changes	Handled on-site, never reflected in the original job record	Captured as a change request tied to the same work order
Invoice audits	Manual cross-checks against scattered paperwork	One audit-ready record per job, matched automatically

Frequently Asked Questions

Q Why is contractor spend so hard to verify in a steel plant?

Work is approved verbally on the floor, hours are logged on paper, and scope changes are handled in the moment, so by the time the invoice arrives there is no single record to check it against.

Q What does a digital work order actually capture?

Approved scope, logged hours per worker, equipment assigned to the job, and any change requests, all tied to one job record that can be matched against the contractor's invoice line by line.

Q Does this slow down contractors on-site?

No, hours and scope changes are logged from a mobile app in the moment, so the record builds itself as the job happens instead of adding paperwork after the fact.

The Results

Contractor invoices stopped being a guessing game. Every job had one record of what was approved, logged, and completed, so overruns were caught before payment instead of argued over after it. Over twelve months that discipline recovered $1.1M and turned invoice audits from a dreaded monthly task into a routine check.
