Measurement of Mechanical, Electrical and Plumbing Installations

At the end of this course, students should be able to: 1. identify and categorise the works that constitute electrical, mechanical and plumbing services in buildings and other construction works; 2. demonstrate the knowledge and understanding of electrical, mechanical and plumbing services technology applicable to buildings and other construction works; and 3. explain and apply the rules of the Building and Engineering Standard Method of Measurement (BESMM) to quantify electrical, mechanical and plumbing services in construction projects. 4. prepare model electrical and mechanical services bill for a typical building using electronic means such as MS Excel and or any of the standard industry software.

Measurement shall include for electrical, mechanical and plumbing installations. Electrical installations: electrical equipment and control gear, conduits, trunking, cables and conductors. Fittings and accessories shall be grouped according to power distribution, Lighting, ventilating, and security system - CCTV, telephones, signals, fire-alarms, burglar-alarms, earthen conductors and lighting conductors. Mechanical and plumbing installations: measurement of cold and hot water supply. Sanitary installations, Air conditioning and gas installation. Firefighting installation. Refuse disposal installation, special equipment including incinerator, refuse chutes. Installation of air handling, automatic control, kitchen equipment, laundry equipment, mechanical movement including lifts, hoists, escalators, conveyors, and associated builders’ works. Production of bill of quantities for the measured works: using manual method, the use of MS Excel and dedicated computer software. Site visits, use of construction pictures and video diaries to aid students’ understanding of the sequence of construction works being measured.
