When designing building systems, an integrated MEP engineering approach yields better results than specifying each building system in isolation. Interactions between building systems can be especially difficult to coordinate when the design process is isolated, and equipment location conflicts are very likely. Mechanical systems that are include elements of infrastructure, plant and machinery, tool and components, heating and ventilation and so on. Electrical systems will include, power supply and distribution, telecommunications, computing instrumentation, control system and so on.MECHANICAL AND ELECTRICAL WORK
