Mechanical engineering encompasses several types of building systems design, including heating, ventilation, air conditioning, plumbing, specialty piping systems and fire protection. Mechanical engineering projects can range from the reuse, retrofit or replacement of existing systems to the design of new central heating and cooling plants. The primary design objective for mechanical systems is to maximize value to the client with a final designed and installed mechanical system. Maximization of value involves more than simply selecting a system with the lowest life cycle cost but needs to incorporate consideration of factors such as future flexibility and redundancy.
Electrical engineering systems design involves medium to low voltage power, emergency generation and distribution, lighting and telecommunication systems. In designing electrical systems, energy efficiency is always a top priority. Systems are designed with respect to future flexibility and growth. Services provided in electrical engineering include a multitude of projects ranging from lights and receptacles for an office renovation to emergency generation.
