Construction Project Management- Insurance
Certificate of Insurance (COI) & Insurance Essentials in Construction
Overview and purpose
COI stands for certificate of insurance; it is a critical document in construction projects.
It provides proof that a contractor or subcontractor carries the required insurance coverage.
Central idea: COIs are a key part of risk management and cost management by mitigating financial risk for all parties.
Why it matters: owners need to verify coverage to ensure claims or accidents are covered; protects against liability exposure.
COIs also verify compliance with contractual requirements and facilitate on-site work initiation.
Real-world friction point: clients sometimes push for immediate mobilization, but work cannot begin without coverage.
COIs foster clear communication among general contractors (GC), subcontractors, and clients by confirming coverage limits and requirements.
Personal note on learning COIs
The speaker is not an insurance expert and found COIs challenging to grasp across multiple projects.
Key question often asked: what coverage is required, and what does that coverage mean in practice?
Common COI requirements on construction projects
Typical document: one COI form that lists several types of coverages with details.
Types of coverage usually included:
General Liability Insurance (GLI) – also known as business liability, commercial general liability (CGL), or comprehensive liability.
Workers’ Compensation Insurance (workers’ comp).
Auto Liability Insurance (coverage for company vehicles used on, between, or around the project).
Professional Liability Insurance (E&O – Errors and Omissions).
Excess Liability / Umbrella Insurance.
Note: Professional liability may or may not apply depending on contractual obligations; avoid paying for unnecessary coverage when not required.
General Liability Insurance (GLI)
Purpose: protects the business from financial losses due to third-party claims.
Covered claims can include:
Bodily injury
Property damage
Personal injury
Advertising injury
Copyright infringement
Reputational harm
Alternate names: commercial general liability insurance or comprehensive liability.
Workers’ Compensation Insurance
Purpose: provides medical care and cash benefits to employees injured or ill while working.
Legal requirement: required by most states; employers pay for it (not employees).
Additional point: may include death benefits to families of employees who die on the job.
Auto Liability Insurance
Purpose: liability coverage for damage or injuries caused by an accident where the contractor or employee is at fault.
Legal requirement: required in most states to legally drive; applies to company vehicles used on or between sites.
Professional Liability Insurance (E&O)
Purpose: protects against claims of negligence in professional services or advice.
Relevance: depends on contractual obligations; covers mistakes in service or advice even if mistakes are unsubstantiated.
When it matters: if you are a professional providing services or advice on a project.
Excess Liability / Umbrella Insurance
Purpose: provides additional coverage when underlying policy limits are exhausted.
Example: if you have a $1,000,000 policy limit and a claim costs $1,500,000, an umbrella could cover the extra .
Note: used to strengthen overall risk protection in case of large claims.
How to read a COI: key data you should see
Insured information: name of the insured (contractor/subcontractor) and contact details.
Insurance company information: name, address, and contact details of the insurer.
Policy information: policy numbers for each type of coverage.
Coverage dates: effective dates (start) and expiration dates (end) of each coverage period.
Coverage limits by type: the limit for GLI, workers’ comp, auto, E&O, umbrella, etc. (e.g., , , etc.).
Additional insureds: identify who is listed as an additional insured (client, GC, etc.).
Cancellation notice: statement indicating the insurer will notify relevant parties of cancellation or material changes.
Project-specific language: any language tying the policy to a particular project or contract.
Signature: an authorized representative from the insurer signs to verify validity.
Practical tip: set reminders to review expiry dates and renewal timelines to avoid gaps during long projects.
4 main elements you should expect on a COI (highlights)
Minimum coverage limits: contracts specify minimum per-type coverage; limits may meet or exceed industry standards and project risk levels; apply the higher of owner/GC requirements to the project.
Additional insured clauses: clients/GCs may require to be added as additional insureds to protect them if a claim relates to the contractor’s work.
Notice of cancellation: insurers must notify project owners if policy cancellation or significant changes occur (typical window around days, but it can vary).
Project-specific language: COI may reference a specific project, property, or contract to ensure policy validity for the work.
Subcontractor Default Insurance (SDI)
What it is: a policy that provides coverage to the GC if a subcontractor fails to fulfill contractual obligations.
Relationship to surety: an alternative to traditional surety bonds.
Coverage scope: costs to complete the work for a defaulted subcontractor, project delays, legal fees, and other additional expenses to finish on time.
Why it matters: allows GC to manage risk directly and take faster action to keep the project on schedule and budget.
Benefits:
Flexibility: SDI covers a portfolio of subcontractors under one policy, often more efficient than multiple bonds.
Efficiency: faster resolution and reduced project delays.
Control: GC can directly manage claims and mitigation processes.
Pre-qualification requirement: GC must prequalify subcontractors (financial stability, performance history) to carry an SDI policy.
Cost considerations: premiums for SDI can be higher than traditional surety bonds; offset by broader coverage and faster claims handling.
Pandemic context: during/after 2020, SDI requirements rose as a precaution, then began to ease back toward prior norms.
Bottom line: SDI is a strategic tool for managing subcontractor risk, helping keep projects on time and on budget.
Builders Risk Insurance (BRI)
Definition: a specialized property policy for buildings under construction.
Key components:
Physical loss or damage: covers the project itself, materials, fixtures, and equipment used or to be installed.
Perils covered: fire, wind, theft, vandalism, weather-related events, and other unforeseen events.
Exclusions: typically excludes earthquakes or floods unless specifically added; excludes events like wear-and-tear, terrorism, employee theft, certain natural disasters unless added.
Coverage period: usually active during construction and can be extended until the project is complete and usable.
Policyholders: can be the property owner, GC, or subcontractors depending on contract and involvement; owner or GC typically provides this.
Cost and budgeting: this is a project cost; know who pays and how it affects the budget.
Additional coverage: can be customized to include soft costs (architectural fees, interest/loan costs), debris removal, delay in completion, etc.
Purpose: to protect against financial losses from damage to the building under construction and keep the project on track financially.
OSIP vs CSIP: Wrap-up Insurance Programs
Purpose of wrap-up programs: consolidate multiple insurance coverages from many parties into a single policy to save money and simplify management.
OSIP (Owner Controlled Insurance Program)
Managed by the project owner.
Coverage typically includes the owner, GC, and subcontractors under one policy for a specific project or set of projects.
Benefits for owners:
Greater control over insurance terms and pricing.
Consistent terms and pricing across the project.
Potential reduction in litigation due to unified coverage.
Drawbacks for contractors:
Limits contractor control over insurance decisions.
Additional administrative burden falls to the owner.
CSIP (Contractor Controlled Insurance Program)
Managed by the GC or construction manager.
Coverage typically includes the contractor and all subcontractors on the project, not the owner.
Benefits for the contractor:
Greater control over insurance process and coverage adequacy for subs.
Enhanced safety management and loss control with unified coverage.
Potential cost savings for the GC/contractor.
Drawbacks for subcontractors:
Greater administrative burden on the contractor to manage requirements.
Subcontractors must adhere to insurance requirements dictated by the contractor; perceived micromanagement by some.
Decision factors:
Project size, owner vs. contractor preference, risk management objectives, and financial considerations.
Summary perspective:
OSIP can reduce owner risk and lower potential for disputes but shifts workload and control away from contractors.
CSIP can improve coordination and loss control but places more administrative responsibility on the contractor.
Practical implications and takeaways
Always reference the higher of the two minimum requirements (owner vs GC) for coverage per type.
Ensure the COI lists all required coverages, proper limits, and correct additional insureds for the project.
Verify the policy period aligns with project schedule; set reminders to refresh or renew as needed.
Confirm who is responsible for providing the Builder’s Risk, SDI, and wrap-up programs in the contract and who pays for them.
Use the COI as a communication tool to ensure all parties understand coverage expectations and obligations.
Example COI portrayal (high-level takeaway)
A COI example from a large project (described as a 9-figure project, over ) demonstrates:
Clear listing of insureds, insurer names, and contact details.
Types of coverage included (GLI, auto, umbrella, workers’ comp, etc.).
Specific policy numbers and active dates.
Explicit coverage limits and who is an additional insured.
Project-specific language and the insured party’s alignment to contract requirements.
Authorized signature at the bottom confirming validity.
The example highlights the importance of ensuring coverages meet or exceed higher project requirements and that all required fields are present.
Quick recap of essential terms
COI: Certificate of Insurance – proof of required coverage and contract compliance.
GLI: General Liability Insurance – third-party claims and listed coverages.

Final practical insight
The COI is not just a form; it’s a living document that should be tracked, updated, and validated throughout the project lifecycle to ensure continuous coverage, compliance, and project continuity.
