Managing commercial general liability policies across a multi-sub construction project is one of the most time-consuming compliance tasks GCs face. A 2024 Marsh Construction Practice survey found that the average GC spends 14 hours per month tracking and verifying CGL coverage across their active subcontractors. The structure you choose for managing these policies directly affects cost, risk exposure, and administrative workload.

This guide compares four approaches to structuring commercial general liability policies on construction projects, with cost data and practical implementation guidance for each.

1. Traditional Program: Each Sub Carries Their Own CGL

In a traditional insurance structure, every subcontractor purchases and maintains their own CGL policy. The GC verifies coverage through certificates of insurance and requires additional insured endorsements naming the GC and owner.

How it works. Each sub buys a CGL policy from their own broker. The GC sets minimum requirements in the subcontract (typically $1M per occurrence, $2M aggregate). The sub provides an ACORD 25 certificate as proof. The GC verifies limits, endorsements, and expiration dates.

Cost structure. Each sub includes their insurance cost in their bid. Insurance typically runs 1.5% to 4% of the sub's contract value, depending on trade, experience modification rate, and claims history. An electrical sub bidding $500,000 might carry $7,500 to $20,000 in CGL premiums built into their price.

Risk allocation. The sub's policy is primary. The GC's policy is excess. If a claim exceeds the sub's limits, the GC's policy fills the gap. Each sub's aggregate is independent, meaning one sub's claim history does not affect another sub's available coverage.

Administrative burden. High. The GC must collect, verify, and track certificates from every sub individually. On a project with 30 subs, that means managing 30 separate policies with different carriers, renewal dates, and endorsement schedules.

Factor	Traditional Program
Premium cost to GC	$0 (subs pay, but build into bids)
GC administrative hours/month	10-20 hours
Certificate tracking	1 per sub
Endorsement verification	Must verify AI, primary/non-contributory, WOS per sub
Risk of coverage gaps	Moderate to high
Best for	Projects under $10M with fewer than 15 subs

2. Owner-Controlled Insurance Program (OCIP)

An OCIP (often called a "wrap-up") is a single insurance program purchased by the project owner that covers the owner, GC, and all enrolled subcontractors under one CGL policy.

How it works. The owner buys a master CGL policy covering the entire project. Subs "enroll" in the program and remove their own CGL coverage for work on that project. Subs reduce their bids by the amount they would have spent on insurance, creating "insurance credit" savings.

Cost structure. OCIPs become cost-effective on projects over $50M. The owner negotiates a single premium based on total project payroll. Consolidated buying power typically yields 10% to 20% savings compared to the sum of individual sub policies. On a $100M project, an OCIP might save $400,000 to $800,000 in total insurance costs.

Risk allocation. All parties share a single policy with a single aggregate. One large claim reduces available coverage for the entire project. Deductibles or self-insured retentions are typically borne by the owner.

Administrative burden. Lower for the GC, but shifted to the owner. The GC does not need to collect individual CGL certificates from enrolled subs. The owner (or their insurance administrator) handles enrollment, payroll audits, and claims management.

GC concerns. Completed operations coverage under an OCIP typically runs 3 to 10 years after project completion. GCs must confirm the tail period meets or exceeds the applicable statute of repose. If the OCIP expires before a latent defect claim surfaces, the GC needs their own coverage to respond.

3. Contractor-Controlled Insurance Program (CCIP)

A CCIP operates like an OCIP, but the GC purchases and administers the master CGL policy instead of the owner.

How it works. The GC buys a project-specific CGL policy covering all enrolled subs. Subs deduct insurance costs from their bids. The GC manages enrollment, payroll reporting, and claims administration.

Cost structure. CCIPs work on projects over $25M. The GC captures the insurance savings rather than the owner. Typical savings range from 8% to 15% compared to traditional programs. A GC on a $50M project might save $150,000 to $300,000 by consolidating coverage.

Risk allocation. The GC controls the policy, which means the GC controls coverage decisions. The GC selects limits, endorsements, carriers, and deductible levels. This control is an advantage for GCs with strong risk management programs.

Administrative burden. The GC takes on significant administrative work: sub enrollment, monthly payroll audits, mid-project adjustments for scope changes, and claims management. Most GCs hire a dedicated insurance administrator or broker to manage a CCIP.

Factor	OCIP	CCIP	Traditional
Who buys the policy	Owner	GC	Each sub
Minimum project size	$50M+	$25M+	Any
Typical savings vs. traditional	10-20%	8-15%	Baseline
GC admin burden	Low	High	High
Claims control	Owner	GC	Sub's insurer
Completed ops tail	3-10 years	3-10 years	Varies by sub
Aggregate shared?	Yes, all parties	Yes, all parties	No, per sub

4. Hybrid Program: Selective Wrap-Up

A hybrid program wraps some subcontractors under a consolidated policy while requiring others to carry their own coverage. This approach lets GCs apply wrap-up economics to high-risk or high-value trades while leaving low-risk trades on traditional coverage.

How it works. The GC purchases a CGL policy covering the GC and selected high-risk trades (demolition, structural steel, roofing, excavation). Lower-risk trades (painting, finish carpentry, landscaping) carry their own policies. The GC manages two tracks: enrolled subs with shared coverage and non-enrolled subs with individual certificates.

Cost structure. Hybrid programs work on projects as small as $10M. The GC consolidates coverage for the trades that drive the highest premiums. A demolition sub paying 5% of contract value for CGL benefits most from wrap-up pricing. A painting sub paying 1.2% generates minimal savings from consolidation.

Risk allocation. Mixed. Enrolled subs share an aggregate. Non-enrolled subs maintain independent aggregates. The GC must track which subs are enrolled and which require individual certificate verification.

Administrative burden. Moderate. The GC manages fewer individual certificates (only non-enrolled subs) but must still administer the wrap-up program for enrolled subs.

5. Rolling Wrap-Up (Multi-Project Program)

A rolling wrap-up extends the consolidated insurance concept across multiple projects rather than a single project.

How it works. The GC purchases a master CGL program that covers all qualifying projects within a defined period (usually three years). Each project enrolls into the program as it starts. Subs on enrolled projects participate in the master program.

Cost structure. Rolling wrap-ups require a GC with consistent annual construction volume of $100M or more. Premium savings increase with volume. GCs with $200M+ annual volume typically save 15% to 25% on CGL costs compared to project-by-project traditional coverage.

Risk allocation. The aggregate applies across all enrolled projects. A catastrophic claim on one project reduces available coverage for every other enrolled project. GCs must monitor aggregate erosion across their entire portfolio.

Administrative burden. Requires a dedicated risk management team or third-party administrator. The GC manages enrollment across multiple projects simultaneously, tracks payroll for dozens or hundreds of subs, and coordinates with a single carrier or program administrator.

How to Choose the Right CGL Program Structure

The decision depends on three factors: project size, number of subcontractors, and your firm's risk management capacity.

Under $10M, fewer than 15 subs. Traditional program. The administrative overhead of a wrap-up does not justify the savings.

$10M to $25M, 15 to 30 subs. Hybrid program. Wrap high-risk trades. Require individual coverage from low-risk trades.

$25M to $100M, 30+ subs. CCIP if the GC has risk management capacity. OCIP if the owner prefers to control the program.

$100M+, ongoing project pipeline. Rolling wrap-up for GCs with consistent volume. Project-specific OCIP or CCIP for one-off large projects.

Regardless of program type, you still need a system to track compliance. Even in a wrap-up, non-enrolled subs require individual certificate verification, and enrolled subs need enrollment confirmation and payroll tracking.

We built SubcontractorAudit to handle both tracks. The platform manages individual certificate collection and verification for traditional and hybrid programs, while providing enrollment tracking and compliance dashboards for wrap-up programs.

Frequently Asked Questions

Can a sub opt out of an OCIP or CCIP? Generally, no. If the subcontract requires enrollment in the wrap-up program, the sub must participate. However, some programs allow subs below a minimum contract value (often $25,000 to $50,000) to remain on their own coverage to avoid enrollment paperwork for small scopes.

Who handles claims in a wrap-up program? The party who purchased the policy (owner for OCIP, GC for CCIP) manages the claims process through the program administrator. Individual subs report incidents to the program administrator rather than their own broker.

What happens to completed operations coverage when a wrap-up ends? The wrap-up policy includes a tail period for completed operations, typically 3 to 10 years. After the tail expires, each party must rely on their own commercial general liability policies for any remaining exposure. GCs should maintain their own CGL coverage with products-completed operations for the full statute of repose period.

Are wrap-up programs available for residential construction? Yes, but they are less common. Residential wrap-ups face challenges with smaller sub contract values, higher sub turnover, and more complex enrollment logistics. Most residential wrap-ups cover projects of 100+ units or $20M+ in value.

How do I calculate insurance credits for subs enrolled in a wrap-up? Insurance credits represent the amount each sub deducts from their bid to account for not needing their own CGL. Credits typically range from 2% to 5% of the sub's contract value. The program administrator provides a schedule of credits by trade classification.

Does an additional insured endorsement still matter in a wrap-up? For enrolled subs, additional insured endorsements on individual policies are not needed because everyone shares the wrap-up policy. For non-enrolled subs in a hybrid program, additional insured endorsements remain necessary. Always verify enrollment status before waiving the AI requirement.
