Reference Clause
Identify the base contract by title and date, state that the addendum modifies specified sections, and confirm which terms remain unchanged to avoid ambiguity.
An addendum preserves continuity with the base subcontract while documenting targeted changes, reducing ambiguity about duties, insurance, and payment. It creates a concise record for accounting, compliance, and dispute resolution without redrafting the full agreement.
Typical users who complete this addendum include contractor project managers, subcontractor representatives, and in-house legal or procurement teams responsible for contract changes.
After signature, distribute the signed addendum to project administrators, accounting, and insurance contacts so obligations and records remain synchronized across teams.
Project managers use addenda to capture scope or sequencing adjustments on active projects, ensuring field teams, vendors, and accounting all refer to the same updated obligations and payment schedule.
Subcontractor owners sign addenda to accept modified scope, confirm insurance coverage and payment terms, and preserve mitigation steps that protect their firm from ambiguous liability or unpaid work.
Identify the base contract by title and date, state that the addendum modifies specified sections, and confirm which terms remain unchanged to avoid ambiguity.

Require signature by authorized representatives, include printed names and titles, and record execution dates to establish the effective amendment date.
