OCP Insurance vs. Builder's Risk for Steel Erection
OCP (Owners and Contractors Protective) insurance is a liability policy that protects a project owner or GC from claims arising from a steel erector's operations. Builder's risk is a property policy covering physical damage to the structure under construction. OCIP is a wrap program that may include both — but it is an entirely different product from OCP. Conflating OCP with OCIP is the most common mistake on this topic, and it leads to real coverage gaps on steel erection projects.
OCP vs. Builder's Risk vs. OCIP: What Each Policy Actually Covers
| Coverage Type | Policy Form | What It Covers | Who Buys It | Who Is Protected |
|---|---|---|---|---|
| OCP Liability | ISO CG 00 09 | Third-party BI/PD liability from a designated contractor's operations | Steel erector (contract condition) | Project owner or GC named on policy |
| Builder's Risk | Property policy | Physical damage to the structure and materials under construction | Owner or GC | All parties with insurable interest |
| OCIP | Wrap program (GL + WC + BR) | GL, workers comp, and often builder's risk for all enrolled participants | Project owner | Owner and all enrolled contractors |
| CCIP | Wrap program (GL + WC) | GL and workers comp for enrolled participants | General contractor | GC and enrolled subcontractors |
| Steel Erector's Own GL | ISO CG 00 01 | Third-party BI/PD from the erector's own operations | Steel erector | Steel erector (plus AI parties) |
How OCP Insurance Works for Steel Erection Projects
ISO form CG 00 09 — the OCP policy form — is a project-specific liability policy that names the project owner or general contractor as the named insured and the steel erector as the designated contractor. Unlike the steel erector's own GL policy, the OCP covers the hiring party's liability for the steel erector's acts, errors, or omissions — not the steel erector's own liability.
Why GCs Require OCP Coverage From Steel Erectors
A GC on a large structural steel project faces a specific exposure: if the steel erector causes a third-party injury or property damage event — a crane load drop, a steel column failure, a worker falling from the frame and landing on a pedestrian below — the GC can be named in the resulting litigation alongside the erector. The GC’s own GL policy covers that exposure, but the GC may prefer to have a separate policy that covers only claims arising from the steel erector’s specific operations, keeping that risk isolated from their own GL aggregate.
The OCP is purchased and paid for by the steel erector as a subcontract requirement, but the GC is the named insured. It typically carries the same limits as the erector’s GL: $1M per occurrence and $2M aggregate. On multi-story commercial steel frame projects or bridge erection jobs, OCP limits of $5M or higher are not uncommon.
What OCP Coverage Does Not Include
The CG 00 09 form is a liability policy only. It does not cover:
- Damage to the steel frame or structure being built (builder’s risk covers this)
- Workers compensation for the steel erector’s employees
- The steel erector’s own property or equipment (inland marine)
- Professional liability for design errors in steel connections
- Pollution liability from welding fumes or coatings
How Builder's Risk Insurance Applies to Steel Erection
Builder’s risk is a property policy, not a liability policy. Where OCP and GL policies respond to claims made by injured third parties, builder’s risk responds to physical damage to the structure being built. For a structural steel erection project, builder’s risk covers:
- The steel frame itself — beams, columns, connection plates, and welded assemblies
- Steel components in transit from the fabricator to the job site
- Steel components stored on-site or in a staging yard
- Soft costs from project delays caused by a covered loss — loan interest, extended general conditions, extended equipment rental
Builder's Risk and Crane Operations: Where the Coverage Gap Lives
A crane collapse during a steel lift can cause multiple distinct losses that fall across multiple coverage lines:
Builder’s risk typically excludes contractor equipment. The crane owner’s equipment floater covers the crane hull.
A dropped beam may be covered under builder’s risk if the steel was part of the permanent structure. It may be covered under rigger’s liability if the beam was not yet incorporated into the structure.
Builder’s risk covers the structure under construction. Damage to an adjacent existing building from a crane swing is a GL or OCP issue.
GL and/or OCP covers this, not builder’s risk.
Rigger’s liability — a specialized inland marine policy — is the coverage layer that explicitly covers loads being lifted. Steel erectors who routinely handle multi-ton structural steel lifts should confirm their rigger’s liability coverage with their agent, since standard GL policies often contain exclusions for load-lifting operations above a specified weight threshold.
When You Need Both OCP and Builder's Risk
Steel erection projects where the GC requires an OCP policy and the project also carries a builder’s risk policy are the norm on large commercial and institutional structural steel jobs. These two policies are complementary, not duplicative: builder’s risk addresses what happens to the structure if it is physically damaged, while OCP addresses who is liable to third parties when the steel erector’s operations cause injury or property damage. A project can suffer both simultaneously — a crane collapse that damages the frame (builder’s risk) and injures a bystander (OCP/GL) — and both policies respond to their respective portion of the loss.
Which Coverage Does a Steel Erection Subcontractor Need?
The coverage picture depends on whether the project uses individual contractor insurance or an OCIP/CCIP wrap program.
Non-Wrapped Projects: Standard Coverage Requirements
On a non-wrapped project, the steel erector subcontractor typically needs:
- Commercial GL ($1M/$2M minimum, often $5M with umbrella)
- Workers comp at statutory limits with $1M EL
- Commercial auto ($1M CSL)
- Umbrella/excess liability ($5M to $10M)
- OCP policy naming the GC as the named insured (if required by subcontract)
- Rigger’s liability (if crane operations are in scope)
- Inland marine / equipment floater (for owned cranes and rigging equipment)
The steel erector does not typically purchase builder’s risk — the GC or owner carries that policy and names the erector as an additional insured with respect to their interest in the structure.
OCIP Projects: The Enrollment Checklist
When a steel erection subcontract requires OCIP enrollment, the steel erector must complete the following before the policy takes effect:
- Complete the OCIP administrator’s online enrollment application, providing payroll estimates by NCCI class code for the project scope
- Receive confirmation of enrollment and review the OCIP coverage summary to confirm GL and workers comp limits, deductibles, and exclusions
- Notify your own GL and workers comp carrier and request the OCIP exclusion endorsement — failure to exclude the project creates double-coverage at audit
- Obtain a certificate of participation from the OCIP administrator and provide it to the GC in place of your standard ACORD 25 COI for this project
- Maintain separate coverage for any work performed outside the OCIP project’s geographic boundaries or scope
- Track the OCIP policy year separately from your own policy year — OCIP workers comp audits are conducted independently
A steel erector enrolled in an OCIP on one project while simultaneously working non-wrapped projects must maintain their own full coverage program for the non-OCIP work. The most common administrative error: failing to exclude the OCIP project payroll from the own-policy audit, resulting in double-counting that inflates the annual premium on both policies.
Conditional Decision Tree: Which Policy Responds to Your Scenario
Builder’s risk — check if the beam was fully incorporated or still being set.
Steel erector’s GL and/or OCP if the GC is sued for the same event.
GL (third-party property damage) — builder’s risk does not cover adjacent existing structures.
Rigger’s liability (load in suspension) and/or builder’s risk (damage to structure).
Workers comp — not GL, not builder’s risk, not OCP.
GL completed operations or professional liability — builder’s risk and OCP do not cover consequential delay damages not tied to physical property damage.

What is OCP insurance and how is it different from OCIP?
OCP (ISO form CG 00 09) is a project-specific liability policy that protects the owner or GC from claims arising from a designated contractor’s operations. OCIP is a comprehensive wrap insurance program that provides GL, workers comp, and often builder’s risk for all enrolled contractors. OCP is a single-contractor liability policy; OCIP is a multi-party wrap program. They are fundamentally different products.
When does a GC require a steel erector to provide OCP coverage?
GCs require OCP policies from steel erectors when the scope involves high catastrophic loss potential — multi-story structural work, heavy crane lifts, or complex framing where a single incident could exhaust the erector’s GL limits and expose the GC to direct liability. The steel erector purchases and pays for the OCP policy, but the GC is the named insured.
What does builder's risk cover on a steel erection project?
Builder’s risk covers physical damage to the structure under construction and materials on-site or in transit. For steel erection, this includes the steel frame, connection hardware, and components damaged by covered perils. It does not cover liability, crane equipment, or adjacent existing structures.
Does builder's risk cover a crane collapse on a steel erection project?
Partially. Damage to the structure from a crane collapse may be covered by builder’s risk. The crane itself is excluded (covered by equipment floater). Third-party injury or property damage from the collapse is a GL/OCP issue. Loads in suspension that are damaged during lifting are a rigger’s liability matter.
What is the difference between OCP insurance and the steel erector's own GL policy?
The steel erector’s GL covers the erector’s own liability. The OCP covers the GC’s or owner’s liability arising from the steel erector’s operations. Both may respond to the same incident from different parties’ perspectives, and both may be required simultaneously by the subcontract agreement.
When does a project use OCIP instead of individual contractor insurance?
OCIPs are typically used on projects over $50M in construction value where the owner can achieve cost savings by consolidating all contractor insurance into a single program. When enrolled, the steel erector’s own GL and workers comp coverage is excluded from the project, and the OCIP provides that protection instead.
How should a steel erector handle an OCIP enrollment requirement?
Complete the OCIP administrator’s enrollment application, request the OCIP exclusion endorsement from your own carrier, obtain a certificate of participation, and track the OCIP project payroll separately from your own policy audit. Failure to exclude the project from your own policy creates double-counting that inflates premiums on both programs.
