A full-coverage service contract provides 100% coverage of labor, parts, and materials as well as emergency service. Owners may purchase this type of contract for all of their building equipment or for only the most critical equipment, depending on their needs. This type of contract should always include comprehensive preventive maintenance for the covered equipment and systems. If it is not already included in the contract, for an additional fee the owner can purchase repair and replacement coverage (sometimes called a “breakdown” insurance policy) for the covered equipment. This makes EG&G ME completely responsible for the equipment. When repair and replacement coverage is part of the agreement, it is to the EG&G’s advantage to perform rigorous preventive maintenance on schedule, since we must replace the equipment if it fails prematurely. Full-coverage contracts are usually the most comprehensive and the most expensive type of agreement in the short term. In the long term, however, such a contract may prove to be the most cost-effective, depending on the owner’s overall O&M objectives. Major advantages of full-coverage contracts are ease of budgeting and the fact that most if not all of the risk is carried by EG&G. However, EG&G is reputable and usually over estimates the requirements of the equipment to be insured, we do enough preventive maintenance to keep the equipment running as long as possible .
