Quick answer: Excavation Insurance Group fields additional insured requests on almost every commercial contract that crosses a client’s desk, and getting the endorsement wrong is one of the fastest ways to get bounced off a bid. Here’s what’s actually being asked for and why it matters.
WHAT “ADDITIONAL INSURED” ACTUALLY MEANS
When a GC or property owner asks to be added as an Additional Insured (AI) on your GL policy, they’re asking to be covered under your liability policy for claims arising out of your work on their project. In plain terms: if your excavation crew damages something and the GC gets sued alongside you, your policy responds on the GC’s behalf too, not just yours. This is standard practice in construction contracting, and refusing or failing to provide it is a common reason a subcontractor gets dropped from a bid before work even starts.
THE DIFFERENCE BETWEEN NAMED AND BLANKET ENDORSEMENTS
There are two common ways this gets handled. A scheduled (named) endorsement adds a specific party for a specific job, which means paperwork every time you land a new contract. A blanket additional insured endorsement automatically extends AI status to any party you’re contractually required to add, without needing a new endorsement issued for every job. For a contractor bidding regularly with multiple GCs, a blanket endorsement saves real time and reduces the risk of a missed or late endorsement holding up a job start.
WHY THIS SHOWS UP ON EVERY COMMERCIAL EXCAVATION CONTRACT
Property owners and GCs want AI status specifically because excavation work carries elevated third-party risk: utility strikes, subsidence, and cave-ins don’t just expose the excavator, they expose everyone up the contract chain. A GC that hired you doesn’t want to be left holding a claim your policy should have covered. This is also why AI requests on excavation contracts often come paired with a request for a waiver of subrogation and higher-than-standard limits, all part of the same risk-transfer logic: push the exposure down to the party actually doing the ground-disturbing work, and make sure that party’s coverage is real.
