COI document

Certificate of insurance tracking for construction packets.

A certificate of insurance is commonly requested during construction onboarding and renewal follow-up, but it needs to be handled carefully as an informational document.

Definition

A certificate of insurance, often called a COI, is a summary document that lists visible insurance information such as insured name, policy types, policy numbers, limits shown on the certificate, insurers, certificate holder, and effective dates.

Why it may be requested

Request reason

GCs may request a COI to keep a record of insurance information supplied by a subcontractor before work begins, before site access, or during renewal follow-up.

Who normally supplies or maintains it

The subcontractor normally asks its broker, agent, or insurance contact for the certificate and keeps the latest version available for GC requests.

Information commonly tracked

  • Insured business name
  • Certificate holder
  • Policy types shown on the certificate
  • Policy numbers and insurers
  • Effective and expiration dates
  • Visible limits or endorsements shown on the certificate
  • Version date and whether a corrected certificate was requested

Common workflow problems

  • An expired certificate remains in a GC folder after a renewed one is issued.
  • A corrected certificate request gets buried in an email thread.
  • The subcontractor has the latest version, but the GC has an older copy.
  • The expiration date is tracked manually and missed during a busy project handoff.
  • A certificate is treated as the whole review instead of one packet item that may need professional review.

Where it fits in a compliance packet

A COI often sits near the front of a subcontractor compliance packet because it changes over time and is frequently requested alongside W-9s, licenses, bonds, OSHA cards, and safety documents.

Disclaimer

A certificate of insurance is informational. It does not independently verify coverage, determine compliance, amend a policy, or replace review by an insurance professional.

Organize the packet around the documents GCs request.
