Contract Administration and Change Order Management

March 15, 2026 Procurement Procurement General Information

Contract Administration and Change Order Management

Effective contract administration is essential to ensuring that Public Housing Authority (PHA) projects, services, and procurement activities are completed efficiently, responsibly, and in accordance with applicable federal regulations and organizational policies.

Once a contract has been awarded, the Housing Authority is responsible for monitoring contractor performance, managing contractual obligations, reviewing expenditures, and maintaining accurate documentation throughout the contract lifecycle.

Proper contract administration also helps protect public resources, promote accountability, minimize financial risks, and ensure that contracted goods and services meet the Housing Authority's operational needs and established quality standards.

1. Understanding Contract Administration

Contract administration is the process of overseeing a contract from award and execution through performance, final acceptance, and closeout.

The Housing Authority's procurement, finance, and program staff may share responsibilities for ensuring that contractual obligations are fulfilled.

A designated Contract Administrator or Project Manager should be assigned to each contract to coordinate contract activities and serve as the primary point of contact between the Housing Authority and the contractor.

Depending on the nature and complexity of the contract, responsibilities may include:

  • Monitoring contractor performance and compliance with contract requirements.
  • Tracking project schedules, milestones, and deliverables.
  • Reviewing the quality and completeness of goods or services received.
  • Coordinating communications with contractors and internal departments.
  • Reviewing invoices and supporting documentation.
  • Identifying and documenting performance concerns or deficiencies.
  • Managing proposed contract modifications and change orders.
  • Maintaining accurate contract records and supporting documentation.
  • Coordinating contract completion and closeout activities.

Contract administrators must operate within their assigned authority. Changes affecting contract scope, pricing, or other contractual obligations must be approved by personnel with appropriate delegated authority.

2. Monitoring Contractor Performance

Contractor performance monitoring helps ensure that goods and services are delivered according to the approved contract specifications, schedules, and performance expectations.

The level of oversight should reflect the contract's value, complexity, duration, and associated risks.

Monitoring activities may include:

  • Reviewing progress reports and project schedules.
  • Conducting site visits or inspections when appropriate.
  • Verifying completed work against contract specifications.
  • Evaluating service quality and performance standards.
  • Documenting missed deadlines, deficiencies, or noncompliance.
  • Maintaining records of contractor communications and corrective actions.

When performance issues are identified, the Contract Administrator should document the concern, notify the appropriate parties, and coordinate corrective action in accordance with the contract.

Significant deficiencies, repeated nonperformance, or potential contract violations should be escalated through the Housing Authority's established management and procurement procedures.

3. Invoice Review and Payment Authorization

Contractor invoices must be reviewed carefully before payment to ensure that charges are accurate, authorized, and supported by adequate documentation.

The Contract Administrator or designated program representative should verify that the invoiced goods or services have been delivered or performed in accordance with the contract.

The review process generally includes:

  1. Contract Verification: Confirm that the invoice corresponds to an authorized contract, purchase order, or approved agreement.
  2. Deliverable Confirmation: Verify that billed goods, services, or completed work have been received and accepted as required.
  3. Pricing Validation: Confirm that rates, quantities, fees, and other charges comply with the contract.
  4. Supporting Documentation: Review timesheets, delivery records, progress reports, inspection records, or other required supporting materials.
  5. Budget and Funding Review: Confirm that sufficient authorized funding is available and that expenditures comply with applicable funding restrictions.
  6. Payment Approval: Route the verified invoice through the Housing Authority's established financial approval process.

Invoices containing discrepancies, unsupported charges, or unauthorized work should be resolved before payment is authorized.

Maintaining separation of duties between contract administration, payment approval, and financial disbursement helps strengthen internal controls and reduce the risk of improper payments.

4. Understanding Contract Change Orders

A change order is a formal modification to an existing contract that may affect the approved scope of work, contract price, project schedule, specifications, or other contractual requirements.

Change orders may become necessary because of unforeseen site conditions, revised operational requirements, design modifications, regulatory changes, or other circumstances affecting contract performance.

Common examples include:

  • Modifications to construction plans or specifications.
  • Additional work necessary to complete an approved project.
  • Adjustments to material quantities or project requirements.
  • Changes to delivery schedules or completion deadlines.
  • Substitution of materials or equipment.
  • Adjustments resulting from documented unforeseen conditions.

A proposed change must be evaluated to determine whether it is permissible under the existing contract and applicable procurement requirements.

Important: A change order should not be used to introduce work that materially exceeds the original contract scope or improperly avoids required competitive procurement procedures.

5. Change Order Review and Approval Process

All proposed contract modifications should follow a documented review and approval process before the affected work is authorized.

Step 1: Identify and Document the Proposed Change

The Contract Administrator or Project Manager identifies the need for a modification and prepares a written description of the proposed change.

Documentation should explain the reason for the modification, the affected contract provisions, and the anticipated operational or financial impact.

Step 2: Evaluate Scope and Procurement Compliance

Procurement staff should determine whether the proposed modification falls within the general scope of the original competitively awarded contract.

The review should consider whether the change materially alters the nature of the work, affects competition, or constitutes a new procurement requirement.

A modification that falls outside the permissible scope of the original contract may require a separate procurement process.

Step 3: Review Cost and Schedule Impacts

The Housing Authority should evaluate the reasonableness of the proposed cost and any requested schedule adjustments.

Depending on the circumstances, this may involve reviewing contractor estimates, labor rates, material costs, supporting documentation, and independent cost estimates or analyses.

The cumulative financial effect of previously approved modifications should also be considered.

Step 4: Obtain Required Internal Approvals

The proposed change order must be submitted through the appropriate approval process established by the Housing Authority's procurement policy and delegated authority structure.

Depending on the contract, approvals may involve the Contract Administrator, Procurement Department, Finance Department, Executive Management, or Board of Commissioners.

Step 5: Execute the Contract Modification

Once approved, the change order must be documented in a formal written contract modification executed by authorized representatives.

The modification should clearly identify:

  • The original contract and applicable change order number.
  • The revised scope or contractual requirements.
  • Any increase or decrease in contract value.
  • Adjustments to project milestones or completion dates.
  • Updated funding or budget information.
  • The effective date and authorized signatures.

Except where an applicable contract provision or authorized procedure permits otherwise, additional work should not begin until the required approvals and written modification have been completed.

6. Preventing Unauthorized Contract Modifications

Housing Authorities must ensure that contract modifications do not undermine the integrity of the original procurement process.

Contract changes must comply with applicable federal procurement standards, HUD requirements, and the Housing Authority's adopted procurement policy.

Particular attention should be given to modifications that:

  • Significantly expand the original scope of work.
  • Introduce substantially different goods or services.
  • Materially alter the contract's purpose or competitive basis.
  • Lack adequate cost justification.
  • Exceed established approval authority or available funding.
  • Divide additional work into smaller modifications to avoid procurement requirements.
  • Authorize work without appropriate written approval.

A contract value increase does not automatically require a new solicitation solely because it exceeds a particular dollar amount. The determination depends on the scope and nature of the modification, the original procurement, and applicable legal and policy requirements.

7. Maintaining Contract Documentation and Records

Complete and accurate contract files are essential for financial accountability, internal reviews, and regulatory audits.

The Housing Authority should maintain documentation sufficient to demonstrate that contract administration decisions were properly authorized, supported, and consistent with applicable requirements.

Contract records may include:

  • Original solicitation and procurement documentation.
  • Contractor proposals and evaluation records.
  • Executed contracts and amendments.
  • Insurance, bonding, and other required compliance documents.
  • Performance reports and inspection records.
  • Contractor correspondence and meeting documentation.
  • Invoices, payment approvals, and supporting financial records.
  • Change order requests, cost analyses, and approval documentation.
  • Notices of deficiencies and corrective actions.
  • Final acceptance and contract closeout documentation.

Records must be retained according to applicable federal, state, local, funding-source, and Housing Authority retention requirements.

8. Contract Closeout Procedures

Contract closeout is the final administrative process used to confirm that all contractual obligations have been satisfied and the Housing Authority's records are complete.

Before closing a contract, the Contract Administrator should coordinate with procurement, finance, and program staff to verify that:

  1. All Deliverables Are Complete: Required goods, services, or construction work have been delivered and accepted.
  2. Outstanding Deficiencies Are Resolved: Identified performance issues and required corrective actions have been addressed.
  3. Final Inspections Are Completed: Required inspections, testing, or acceptance procedures have been documented.
  4. Financial Obligations Are Reconciled: Invoices, approved change orders, retainage, credits, and outstanding balances have been reviewed.
  5. Required Documents Are Collected: Warranties, operating manuals, certifications, lien waivers or releases when applicable, and other required closeout documents have been obtained.
  6. Final Payment Is Authorized: Payment is processed according to contract terms and applicable financial requirements.
  7. Contract Records Are Finalized: The complete contract file is organized and retained according to the applicable records retention schedule.

For construction projects, additional closeout requirements may include final inspections, punch-list completion, warranty documentation, bonding requirements, and applicable lien-related documentation.

9. Accountability and Internal Controls

Effective contract administration requires clearly defined responsibilities, consistent documentation, and appropriate management oversight.

Housing Authority personnel should follow established internal controls to ensure that contract decisions are transparent, expenditures are properly authorized, and procurement requirements are consistently applied.

Employees involved in contract administration must also comply with applicable conflict-of-interest and ethical conduct requirements.

Contractors should not be permitted to perform unauthorized additional work based solely on informal conversations or verbal instructions from personnel who lack contractual approval authority.

Questions or Additional Assistance

Housing Authority employees, contractors, and vendors who have questions about contract administration, invoice requirements, proposed change orders, or contract closeout procedures should contact the Housing Authority's Procurement Department or designated Contract Administrator.

All contract-related requests should be submitted through the appropriate administrative channels to ensure that decisions are properly reviewed, approved, and documented.
