Designing and building all works related to mechanical systems is a critical process in engineering, construction, and industrial projects. Mechanical systems include heating, ventilation, and air conditioning (HVAC), plumbing, fire protection, and other mechanical installations that ensure the functionality, safety, and comfort of buildings and facilities.

The design phase begins with understanding the project requirements and constraints. Engineers analyze factors such as building usage, energy efficiency, safety standards, and sustainability goals. They develop detailed calculations, system layouts, and equipment specifications to ensure optimal performance. Modern design practices often use advanced tools such as computer-aided design (CAD) and building information modeling (BIM) to create accurate and coordinated mechanical system drawings.
