Understanding Retainage for ICI Subcontractors#

Executive Summary#

Retainage is a percentage of each progress payment withheld by the payer until project completion or other release triggers. For ICI subcontractors, retainage affects cash flow throughout projects and accumulates into significant amounts awaiting release. Understanding how retainage works, what triggers release, and how to manage retained funds helps subcontractors plan cash flow and recover what they are owed.

The Context for ICI Subcontractors#

Retainage has been a construction industry practice for over a century. The concept is straightforward: withhold a portion of payment as security against incomplete work, defects, or contractor default. When the work is complete and acceptable, release the retained amount.

For subcontractors, retainage flows through multiple levels. The owner withholds from the general contractor. The GC withholds from subcontractors. The subcontractor may withhold from their own subcontractors or suppliers.

While retainage serves legitimate purposes, it also creates cash flow challenges for subcontractors who must fund work while a portion of their earned revenue is held back.

How Retainage Works#

Typical Retainage Rates#

Retainage rates vary by project, owner, and jurisdiction:

Common rates: 5% and 10% are most common. Some jurisdictions cap retainage rates by statute.

Reduced retainage: Some contracts reduce retainage after a certain completion percentage. A contract might withhold 10% until 50% completion, then reduce to 5%.

No retainage: Some owners and projects do not withhold retainage, though this is less common.

Calculation Example#

Consider a subcontractor with a $500,000 contract and 10% retainage:

Progress Billing	Gross Amount	Retainage (10%)	Net Payment
Billing #1 (20%)	$100,000	$10,000	$90,000
Billing #2 (30%)	$150,000	$15,000	$135,000
Billing #3 (30%)	$150,000	$15,000	$135,000
Billing #4 (20%)	$100,000	$10,000	$90,000
Total	$500,000	$50,000	$450,000

At project completion, $50,000 in retainage awaits release.

Retainage on Change Orders#

Change orders typically follow the same retainage provisions as the original contract. If the contract specifies 10% retainage, change order payments are also subject to 10% retainage.

Some contracts specify different retainage treatment for change orders. Review contract language to understand how change order retainage is handled.

Cash Flow Impact#

Working Capital Requirements#

Retainage increases working capital requirements. The subcontractor must fund:

Labor costs paid weekly or biweekly
Material costs paid per supplier terms
Equipment and overhead costs ongoing

Meanwhile, 5-10% of earned revenue is held back. On large or long-duration projects, retained amounts become significant.

A subcontractor with $2 million in annual revenue at 10% retainage might have $200,000 or more in retained funds at any given time—capital that is earned but not yet received.

Timing Uncertainty#

Retainage release timing is often uncertain:

When will substantial completion occur?
When will the owner release retainage to the GC?
When will the GC release to subcontractors?

This uncertainty complicates cash flow planning. The subcontractor knows retainage will eventually be released but cannot predict exactly when.

Multiple Project Accumulation#

Subcontractors working on multiple projects accumulate retainage across all of them. Each project holds back funds. Some projects complete and release retainage while new projects accumulate more.

Managing this portfolio of retained funds—tracking what is held where and when it might be released—requires attention.

Retainage Release#

Release Triggers#

Retainage is typically released when specific conditions are met:

Substantial completion: The work is sufficiently complete that the owner can use it for its intended purpose. Punch list items may remain, but the work is substantially done.

Final completion: All work, including punch list items, is complete. All required documentation has been submitted.

Acceptance: The owner formally accepts the work.

Time period: Some contracts release retainage after a specified time period following completion.

Partial release: Some contracts allow partial release at substantial completion with the remainder held until final completion.

The Release Process#

Retainage release typically flows through the contract chain:

Owner releases retainage to GC
GC processes release
GC releases retainage to subcontractor
Subcontractor releases to any lower-tier parties

Each step takes time. Even after subcontractor work is complete, release may be delayed waiting for:

Other subcontractors to complete their work
GC to compile final documentation
Owner to process final payment
Administrative processing at each level

Documentation for Release#

Releasing retainage typically requires documentation:

Final lien waivers
Warranty documentation
As-built drawings if required
Operation and maintenance manuals if required
Certification of completion
Final inspection sign-off

Missing documentation can delay release. Subcontractors should prepare closeout documentation proactively.

Retainage Laws and Regulations#

State Retainage Laws#

Many U.S. states have laws governing retainage on construction projects:

Rate caps: Some states limit how much can be retained. California, for example, recently limited retainage on private projects to 5% (previously 10% was common).

Release timing: Some states specify how quickly retainage must be released after completion.

Public vs. private: Different rules may apply to public projects versus private projects.

Interest: Some states require interest on retained funds.

Subcontractors should understand the retainage laws in states where they work. These laws may provide protections beyond what contracts specify.

Federal Projects#

Federal construction projects are subject to the Prompt Payment Act, which includes provisions governing retainage and payment timing.

Canadian Requirements#

Canadian provinces have varying requirements regarding holdbacks (the Canadian term for retainage). Construction lien acts typically address holdback requirements and release timing.

In Ontario, for example, the Construction Act requires a basic holdback and specifies release conditions.

Managing Retainage#

Tracking Retained Amounts#

Accurate tracking is essential:

How much has been retained on each project?
What is the total retainage across all projects?
When is each amount expected to be released?

This tracking informs cash flow planning and ensures retained amounts are not forgotten.

Pursuing Release#

Subcontractors should actively pursue retainage release:

Complete work promptly: Finish punch list items quickly. Do not let small incomplete items delay release.

Submit documentation: Provide all required closeout documentation without being asked. Proactive submission accelerates release.

Follow up regularly: Check on release status. Ask when release is expected. Identify and resolve obstacles.

Escalate when necessary: If release is unreasonably delayed, escalate through appropriate channels.

Contract Negotiation#

Where possible, negotiate favorable retainage terms:

Lower rates: 5% rather than 10% where the contractor has leverage

Earlier reduction: Reduce retainage percentage at earlier completion milestones

Prompt release: Specific commitments on release timing

Subcontractor protection: Ensure GC retainage release to subcontractors is tied to owner release to GC, not to overall project completion

Smaller subcontractors may have limited negotiating power on large GC contracts, but understanding what to ask for positions contractors to negotiate when opportunities arise.

Cash Flow Planning#

Plan for retainage impact on cash flow:

Project cash flow: Model project cash flow including retainage to understand working capital needs

Portfolio view: Understand total retained funds across all active projects

Release forecasting: Estimate when retained amounts will be released based on project schedules

Financing consideration: If retainage creates cash flow constraints, consider financing options (though financing costs reduce effective margins)

Common Retainage Issues#

Delayed Release#

The most common issue is delayed release:

Project completion delays
GC delays in processing
Owner delays in payment
Documentation disputes

Subcontractors may have completed their work months ago but remain waiting for release tied to overall project status.

Unjustified Withholding#

Sometimes retainage is withheld without valid justification:

Disputes unrelated to the subcontractor's work
Administrative failures
Cash flow problems upstream

Understanding legal protections and actively pursuing release helps address unjustified withholding.

Offset Against Claims#

Payers sometimes attempt to offset retainage against claims:

Alleged deficiencies
Back-charges
Liquidated damages

Subcontractors should carefully evaluate whether offsets are legitimate and dispute unjustified offsets.

Bankruptcy#

If the GC or owner experiences financial difficulty or bankruptcy, retained funds may be at risk. Understanding payment protections (mechanic's liens, payment bonds) helps protect subcontractor interests.

Protecting Retainage Rights#

Lien Rights#

Mechanic's lien rights typically protect retained amounts. Maintaining lien rights—which requires compliance with notice and filing requirements—protects the subcontractor's ability to collect retained funds.

Payment Bonds#

On bonded projects, the payment bond provides an additional avenue to collect retained amounts if the GC fails to pay.

Documentation#

Maintain documentation supporting retainage claims:

Contracts showing retainage terms
Progress billings showing amounts retained
Correspondence regarding release
Completion documentation

Good documentation supports collection efforts if disputes arise.

How Appello Supports Retainage Management#

Appello's Progress Billing & Invoicing module tracks retainage on each project, maintaining visibility into retained amounts and accumulated totals. The system calculates retainage based on contract terms and tracks release as payments are received.

This tracking integrates with job costing, providing accurate project financial visibility that accounts for retained amounts not yet received.

Conclusion#

Retainage is a standard construction industry practice that affects every subcontractor's cash flow. Understanding how retainage works, planning for its impact, actively pursuing release, and protecting legal rights helps subcontractors manage this reality.

While retainage cannot typically be avoided entirely, informed management reduces its negative impact and ensures that earned funds are eventually recovered.
