SYNOPSIS
This course is a service course from the Faculty of Mechanical Engineering & The Faculty of Electrical
Engineering.The course will exposed civil engineering students to the fundamentals of Mechanical &
Electrical building services. The topics to be covered in the Mechanical Portions are design of Domestics
Water Supply System, Fire Prevention System, Ventilation and Air-Conditioning System and Lift and
Escalators System. Students will be exposed more on design using professional charts and codes and
catalogues from manufacturers.
The electrical portion of the course covers single phase and three phase system followed by an insight to
transformer and induction motor operation. The electrical section will also cover the commercial practice
of electrical wiring and substation design. At the end of the course, students should be able to
demonstrate the understanding of electrical system and machines operation and ability to design
domestic wiring system.
