Inquiry #34: Section 7-1.06B, Item 3 states that all insurance must be with an insurance company with an AM best Financial Strength Rating of A- or better and a Financial Size Category of VII or better. Contractor's Construction Workers Compensation coverage is through State Fund, which is not rated by AM Best. Please confirm this is acceptable and compliant and would be approved by Caltrans to allow the contractor to submit their proposal.
· Contractor's current ROM estimate is $11.7M. Section 7-1.06D(2) states that bids totaling $10M to $25M require a $2M/$4M for GL with $15M in Umbrella/Excess Liability limits. Contractor currently maintains a $1M/$2M for GL with a $10M Umbrella. Increasing the primary GL limits to $2M/$4M will be costly and subject to the carrier’s approval. It may be more cost effective to place a 2nd Excess Liability policy over the existing program to satisfy the total limit requirements ($17M/$19M). To meet this limit requirement, we would need to place a $7M Excess. Please confirm this is acceptable and compliant and this would be approved by Caltrans to allow the contractor to submit their proposal?
· Section 7-1.06E(2) states that the $15M Umbrella/Excess Liability requirement stipulated in Section 7-1.06D(2) also applies to Auto Liability. Per the comments above, the contractor currently maintains a $10M Umbrella so we would need to place a 2nd Excess Liability policy over our existing program to meet this requirement. Please confirm if this would be required, if so, and if this requirement was to be met, would the contractor be approved and would Caltrans allow the contractor to submit our proposal?
