Parties
Identify legal names and contact information for the contracting business and the subcontractor, including business entity type and authorized representative details.
Using a formal Business Sub CO Agreement protects both parties by creating an auditable record of scope, cost, and schedule changes, and it reduces ambiguity about payment triggers, insurance, and warranty obligations. It also creates a written basis for dispute resolution and evidence for compliance reviews or audits.
Ensure the signer has the authority to bind the party and that procurement and legal have reviewed contract exhibits and insurance certificates.
A contracts manager reviews change orders and amendments to confirm scope, pricing, and schedule impacts; they ensure language aligns with master services agreements and that insurance and indemnity clauses remain intact.
The subcontractor owner or authorized officer signs to accept revised scope and payment terms; their signature confirms capacity, performance commitments, and acknowledgement of any new conditions or required deliverables.
Identify legal names and contact information for the contracting business and the subcontractor, including business entity type and authorized representative details.
Describe the precise work, deliverables, milestones, excluded services, and any referenced exhibits or technical attachments that modify the original contract scope.
State adjusted pricing, payment schedule, retainage if applicable, invoicing requirements, and conditions precedent to payment such as inspections or acceptance signoffs.
Specify revised start and completion dates, time-impact assessment procedures, and liquidated damages or incentive provisions when relevant.
List required insurance coverages, limits, additional insured requirements, and indemnity obligations tied to the change order activities.
Define testing, inspection, acceptance criteria, and the governing law, venue, and escalation steps for resolving disagreements, including mediation/arbitration if chosen.

Time required to notify subcontractor of change (project-specific; document this date)
Internal approval target (often 3–10 business days depending on complexity)
Date by which both parties must sign to keep schedule intact

Escalation timeframe for unresolved issues, e.g., 30 days from notice
