Diploma in Mechanical Quantity Surveying

Explore the main HVAC system types: window, split, centralized, and district cooling. Note that window units are outdated and split systems use indoor and outdoor components.

Explore how the centralized air conditioning system uses duct takeoff and district cooling concepts, detailing central chiller plant, distribution network, user station, and water treatment.

Explore duct ancillaries such as volume control dampers, backdraft dampers, fire dampers, and flexible connectors, and learn how they regulate air volume, provide one-way airflow, and automatically close on fire.

Explore key ductwork ancillaries, including supply and return diffusers, access panels and doors, volume dampers, ceiling diffusers, grills, fan coil units, thermostats, duct flow indicators, and motorized smoke dampers.

Understand hvac ducting and insulation, including galvanized steel vs aluminium ducts, rigid and flexible types, and insulation methods such as duct wrap, liner, board, and blanket.

Explore motorized valves for central heating to control water flow and protect pumps with strainers; review regulating, isolating and self actuated valves, plus temperature gauges and condensate drains.

Calculate rectangular duct weight by deriving area from perimeter and dimensions, apply Smacna standard gauge 24 for kg/m², and include insulation, dampers, diffusers, with wastage allowance.

Learn to take off a chilled water system by reading drawings and legends, then measure pipe diameters and lengths and count fan coil units, wall packages, and isolation walls.

Learn to prepare a bill of quantities for a chilled water system by calculating pipe lengths for supply and return lines, applying appropriate allowances, and itemizing insulation and fittings.

Explore fire extinguisher types by form and color, their suitable applications for class a–f fires, and proper use steps, plus hose reel systems in building protection.

Demonstrates FM 200 fire suppression system, with detectors and alarms, nozzle discharge, extinguishing fire quickly via heat absorption and chemical contribution in waterless system with a small amount of agent.

Explore alarm check valve assemblies that control water to sprinkler systems, OS and Y gate valves, and zone control valves XV that stop water after a fire.

Explore fire alarm and voice evacuation systems, including smoke and heat detectors, duct detectors, remote indicators, manual and automatic full stations, and single/dual input monitor modules with relays.

Prepare firefighting system quantities by item description, quantity, unit, rate, and amount, include contractor remarks, measure pipes in AutoCAD, and apply 10% length allowance and rate analysis.

Learn the electrical installation of fire alarm systems within building projects, including accessories, subcircuits, cabling, and rate analysis for takeoffs in mechanical, electrical, and plumbing works.

In the diploma in mechanical quantity surveying, learn how to install planswift, a key tool discussed in the course.

In Planswift training 02, learn to set the scale on your drawing and input 65.15 m to reduce error. Then master measuring quantities and square values.
