GL may address covered resulting injury, property damage or loss of use if the actual underground work is accepted. Review damaged interests, work-property terms and economic outage demands separately. Preserve utility verification; markings or an unmarked private line alone do not decide responsibility or coverage.

Mobile equipment like trenchers, plows, and mini-excavators is commonly scheduled on an inland marine policy, which may cover them in transit and at job sites, subject to policy terms.

Liability terms may address covered resulting property damage under actual completed-work, water and work-property terms. Identify the cause, affected property, installation settings, and owner maintenance, and review any fungi allegation separately. Valve replacement, redesign, reprogramming and a watering warranty do not automatically follow from a damage claim; later discovery alone does not select a responding policy.

Workers' compensation may provide qualifying employee injury benefits under applicable law. Review actual employers, work states, payroll, and trenching, lifting, and equipment duties. A seasonal or subcontracted crew label does not settle employee status, and third-party liability is not a substitute for employee benefits.

Cross-connection to potable water can raise contamination and testing questions. Describe actual connection, device installation, testing, and maintenance duties and relevant water-authority requirements. Liability or pollution terms may address covered resulting harm only if the operation and contaminant are included; a credential, BOP or excess limit does not establish that acceptance or pay every compliance cost.

A BOP may combine covered premises property and liability if the business qualifies, while inland marine may address insured mobile tools and machines. Confirm actual stock, transit, off-site storage, rentals and installed customer systems rather than assume a package automatically includes each interest or that a particular extension is available.
