Milestone Schedule
Define discrete work stages, acceptance criteria, and deliverables that trigger each payment tranche; avoid vague milestone descriptions that invite interpretation disputes.
Using a waterfall contract clarifies milestone-linked payments, reduces disputes over partial work, and creates predictable cash flow. It improves visibility into who gets paid and when, supports lien waiver sequencing, and provides a clearer basis for change-order valuation and risk allocation.
The Waterfall Construction Contract is used by owners, general contractors, lenders, and specialty subcontractors who require staged payment certainty tied to milestone completion.
Roles vary by project size; parties should confirm signatory authority and required attachments before executing the agreement.
Project-level signatory responsible for certifying milestone completion, submitting draw requests, and coordinating subcontractor lien waivers. The GC often manages inspection signoffs, progress schedules, and retains responsibility for coordinating change orders and their associated cost adjustments.
Owner or lender approves milestone releases after receiving required documentation. They typically condition payment on certified draws, lien waivers, invoices, and any lender-required insurance or compliance certificates tied to each waterfall tranche.
Define discrete work stages, acceptance criteria, and deliverables that trigger each payment tranche; avoid vague milestone descriptions that invite interpretation disputes.
Specify the order of payment recipients, percentages per tranche, retainage amounts, and the mechanics for allocating funds among subcontractors and suppliers.
List required invoices, lien waivers, inspection certificates, insurance proofs, and requisition forms that must accompany each draw request for payment release.
Set a formal approval path for scope changes, pricing adjustments, and schedule impacts, including contingency draw rights and revised milestone sequencing.
Include a clear mechanism for unresolved payment or performance disputes: arbitration, mediation, or court jurisdiction along with interim relief procedures.
Describe default events, cure periods, remedies, and post-termination accounting, including how remaining funds are distributed under the waterfall.
| Field | Configuration |
|---|---|
| Signature Order | Sequential signer order with required approver steps |
| Authentication | Email + SMS OTP or ID verification for higher assurance |
| Notifications | Auto-notify pending signers and copy stakeholders |
| Template Name | Use consistent project-specific template identifiers |
Ensure the chosen eSignature platform supports the authentication, audit trail, and document formats needed for construction draws.
Confirm platform compliance for your industry (for example HIPAA BAA if health-related information exists) and ensure APIs or native integrations connect to your accounting and project management systems.
Project start date; mobilization typically begins immediately thereafter.
Each milestone needs a calendar date or percentage completion marker.
Commonly Net 30 from invoice or approval date.
Often released 30–60 days after final completion.
Specify owner response period, commonly 7–21 days.
Agreement execution and initial mobilization activities.
Completion of staged work items triggering partial payments.
Major handover point; often triggers large disbursement.
Punchlist resolution and final retainage release.
