Unrecovered change order costs at mid-market general contractors

Where the margin leakage starts

Unrecovered change order costs start when out-of-scope work is done after verbal authorization on the jobsite, then fails to convert into a formal Change Event. Site Superintendents often move fast to avoid costly schedule delays, especially when design clashes or spontaneous owner requests appear. By the time Financial Controllers see the expanded scope, the physical work may already be buried behind drywall or poured in concrete.

Out-of-scope work becomes an accounting problem the moment a Site Superintendent verbally authorizes specialty subcontractors on the jobsite to keep work moving, driven by design clashes or spontaneous owner requests. The schedule pressure is real, so administrative compliance loses. Later, the general contractor faces an evidence gap because the work is already buried behind drywall or poured in concrete, making retroactive cost justification to the developer hard. ^{[3]O*NET 47-1011 (First-Line Supervisors of Construc…}

Project Managers and Financial Controllers then inherit the fallout: operational actions at the jobsite do not automatically translate into formal Change Events inside accounting systems. When unstructured proof of the out-of-scope work stays siloed, the general contractor absorbs unapproved subcontractor labor and material costs instead of billing them. This is why margin bleed keeps showing up as a delayed accounting surprise.
