Change Order and Approval Process

All changes affecting time, scope or cost must be documented as a written change order and approved in accordance with the original contract change control procedure. No change is effective until both parties have executed a change order that identifies the scope change, the price adjustment, the revised schedule and any impact to other contract provisions.

Confidentiality

Each party shall maintain in confidence all proprietary and confidential information received from the other party in connection with the project. Confidential information shall not be disclosed except to those employees, contractors or agents who have a need to know, and shall be protected by the receiving party using no less than reasonable care. This confidentiality obligation survives termination of the contract and this extension for a period of three years.

Liability, Indemnity and Insurance

Insurance requirements in the original contract remain in force and are not reduced by this extension.

Force Majeure

Neither party shall be liable for delays or failures to perform caused by events beyond its reasonable control, including but not limited to acts of God, labor disputes, governmental actions, or severe weather. Affected party shall provide prompt written notice and use commercially reasonable efforts to mitigate the impact.

What the Project Management Construction Extension is and when it applies

The Project Management Construction Extension is a written amendment to an existing construction contract that adjusts schedule, scope, or budget terms without creating a new primary agreement. Typical uses include agreed time extensions for weather or change orders, adjusted milestone dates, and clarifications of deliverables. The extension preserves the original contract's general terms while documenting the precise changes, responsibilities, and any additional consideration. Properly executed extensions reduce disputes by creating an auditable record of agreed changes and preserving notice, mitigation, and claim rights under the original contract.

Why a formal extension matters in construction projects

A written Project Management Construction Extension creates a clear, enforceable record of changes to schedule, cost, or scope and helps avoid claims and liquidated damages. It ensures both parties acknowledge the new timeline, any extra compensation, and revised responsibilities in a single, dated document.

Why a formal extension matters in construction projects

Who typically completes and approves these extensions

Project managers, general contractors, owners, and subcontractors are the primary users of construction extensions and amendments.

  • Project managers and superintendents who track schedule and coordinate change orders on active sites.
  • General contractors and subcontractors that need written agreement for altered scopes, pricing, or time.
  • Owners, construction managers, or design professionals who must formally accept revised deliverables and dates.

Each signer should have authority to bind their organization; signatures should record names, titles, and dates to support enforceability.

Key signatories and decision-makers

Project Manager

A licensed or appointed manager who tracks milestones and authorizes operational changes. Their signature documents acceptance of revised timelines and any operational impacts to downstream trades.

Authorized Signatory

An officer or delegated representative of the contractor or owner who has legal authority to commit the organization to additional time, cost, or contractual obligations documented in the extension.

Core elements to include in a professional construction extension

A complete extension should be concise but comprehensive, focusing on what changes, when they start, who approves them, and how they affect the original contract's terms.

Reference

Cite the original contract by title, date, and contract number so the amendment clearly attaches to the correct agreement and avoids ambiguity.

Scope Change

Describe specific additions, deletions, or substitutions in deliverables and tie each change to drawings, RFIs, or change order numbers.

Time Adjustment

State the new milestone or completion dates, define the effective extension period, and note any interim milestones affected.

Consideration

Record any additional payment, credits, or cost-neutral adjustments tied to the extension, with payment terms and invoicing instructions.

Claims Waiver

Specify whether entering the extension releases, preserves, or limits claims related to the subject matter, using clear, narrowly tailored language.

Signatures

Include printed name, title, organization, signature, and date for each party; indicate whether signatures may be electronic or require notarization.

Step-by-step: preparing and executing the extension

Follow a consistent sequence: verify authority, document the change, confirm costs, secure signatures, and distribute executed copies.

  • 01
    Verify Authority: Confirm who can bind each party before drafting.
  • 02
    Document Change: Draft precise scope, dates, and financial impact.
  • 03
    Approve Costs: Obtain internal approvals or budget sign-off.
  • 04
    Execute & Distribute: Collect signatures and share final copies to stakeholders.

Typical execution flow for an online construction extension

Electronic workflows streamline review, signature, and distribution while preserving an audit trail for each action and signer.

  • Upload Document: Sender uploads the extension document to the eSignature platform.
  • Add Fields: Place signature, date, and required input fields for each party.
  • Invite Signers: Send signing links by email or SMS to each authorized signer.
  • Capture Audit Trail: Platform logs timestamps, IPs, and actions for legal evidence.

Recommended digital workflow settings for extensions

Configure the signing workflow to match contractual approval order and required authentication strength for the document.

Field Configuration
Signing Order Set sequential or parallel order per contract requirements.
Authentication Use email link or SMS code; add KBA if higher assurance needed.
Attachments Attach referenced COs, RFIs, or revised drawings.
Retention Ensure platform stores a tamper-evident final PDF and audit log.

Digital signing and platform integration considerations

Choose a platform that supports secure eSignatures, audit trails, and the integrations your team uses.

  • Integration Needs: Salesforce, NetSuite, or Procore integration may be required.
  • Document Types: Support for PDF, DOCX, and embedded attachments is needed.
  • Authentication: Offer SMS, email, or advanced verifier options.

Validate vendor certifications for HIPAA, SOC 2, and eSignature legal compliance if handling regulated data or enterprise workflows.

Security, encryption, and compliance checklist for e-execution

Transport Encryption: TLS 1.2/1.3 in transit
Data at Rest: AES-256 encryption at rest
Audit Trail: Comprehensive timestamp and IP logging
Standards: SOC 2 Type II and ISO 27001 available
Regulatory: ESIGN and UETA compliant
Health Data: HIPAA support with BAA option

Risks and consequences of an incomplete or improper extension

Schedule Exposure: Potential liquidated damages or extended delays
Claim Waiver: Unintended release of future claims
Payment Dispute: Delayed or withheld compensation
Enforceability: Ambiguous terms may be voided
Regulatory Risk: Privacy breaches if PII included
Record Loss: Missing audit trail harms evidence

Common mistakes to avoid when preparing an extension

  • Using vague dates or milestone language that leaves room for differing interpretations and future disputes.
  • Failing to reference the original contract precisely, which can create uncertainty over which terms remain in force.
  • Skipping internal approvals or signing authority checks, causing later invalidation or payment disputes.
  • Not capturing a clear statement on whether the extension preserves, waives, or limits related claims.

Time-sensitive actions and typical deadlines to track

Extensions typically trigger notice deadlines and internal approval timeframes; track each deadline so rights and remedies are preserved.

Notice to Owner:

Provide formal written notice within contract-specified days (commonly 7–14 days).

Subcontractor Claims:

File claims within the prime contract's claim submission window, often 14–30 days.

Change Order Approval:

Allow owner review and signature within agreed review period, typically 15–30 days.

Extension Decision:

Document owner approval or denial within contract-defined response time.

Retention of Records:

Keep executed extensions and supporting documents for required retention period.

Real-world examples using digital execution for construction documents

Practical examples show how teams use extensions and eSign to keep projects moving while preserving records.

Martin Properties (Field Execution)

Tim Martin used eSign to execute extension agreements on mobile while onsite, speeding approvals.

  • Mobile signatures removed the need for in-person collection.
  • The team preserved compliance and security, producing signed PDFs and audit logs that satisfied owners and sped payment processing without on-site meetings.

BIS (Corporate Compliance)

Dan Rotelli selected a SOC 2–certified workflow to handle contract amendments across multiple projects.

  • Security and audit capability mattered.
  • The solution gave legal and finance teams a single source of truth for executed extensions and helped resolve scheduling disputes with documented timelines and signer metadata.

Practical tips for precise, enforceable extensions

Adopt these practices to reduce ambiguity and increase enforceability when issuing or accepting an extension.

Reference the baseline
Always identify the original contract by number and date and attach relevant change order documents to avoid confusion over scope or precedence.
Be specific with dates
Use exact MM/DD/YYYY dates for effective, milestone, and completion dates to prevent differing interpretations and claims.
Document consideration
If extra payment is due, state the exact amount, payment timing, and invoicing references to eliminate downstream disputes.
Retain full audit trail
Store the executed PDF, platform audit log, and supporting attachments together to preserve evidence for disputes or audits.
