Erection All Risks (EAR) Insurance — written in connection with construction projects outside the United States, EAR policies are designed to cover the risk of loss arising out of the erection and installation of machinery, plant and steel structures, including physical damage to the contract works, equipment and machinery, and liability for third-party bodily injury (BI) or property damage (PD) arising out of these operations. Coverage for delay in start-up (DSU) costs is typically an optional coverage. Covered parties include the general contractor, subcontractors, and in some cases suppliers and manufacturers of equipment. Examples of the types of projects for which EAR coverage is typically purchased include power plants, manufacturing and fabrication facilities, water and wastewater treatment facilities, and telecommunications centers (particularly where the erection of signal towers is involved). Some insurers combine EAR and contractors all risks (CAR) coverages into one form. Although these terms are sometimes used interchangeably, there are some substantive differences.
