Study Notes

Mechanical Installations

Categories include heating, ventilation, air conditioning, fire protection, gas systems, refrigeration, and compressed air.
Essential for maintaining environmental comfort and safety in buildings.

Pipework

Required for various mechanical installations such as fire water systems and HVAC refrigerant circulation.
Insulation is crucial for keeping refrigerant cool and minimizing energy loss.
Special measurement considerations apply to:
- Prescribed cut lengths (higher cost)
- Pipes chased into walls (higher installation cost)
Fittings larger than 60mm in diameter must be measured separately, reflecting increased expense.

Pipe Trenching

Method A involves trenches not exceeding 1000mm deep, with specific bedding and filling requirements.
Method B focuses on insulation, protective wrappings, coatings, and linings for pipework.

Ductwork

Ducting types include:
- Rectangular low pressure
- Round low pressure
- Other rectangular ducting
Ducting fittings and flexible ducts play a critical role in ensuring airflow and system efficiency.

Insulation and Protection for Ductwork

Essential for maintaining energy efficiency and performance.
Measurements taken for insulation and protective coverings are expressed in square meters.

Duct Calculations

For rectangular low pressure galvanised ducting, dimensions are crucial for accurate area calculation.
Categories help determine installation specifications and costs based on size and shape changes.

Ducting Fittings and Flexible Ducting

Essential components measured separately for accurate costing and effective system performance.

Diffusers, Grilles, and Accessories

Various types of air distribution manufactures such as diffusers, grilles, attenuators, dampers, and filters must be cataloged and accounted for in the installation process.

Lift, Hoist, Escalator and Conveyor Installations

Lift installations include various components such as cars, power units, ropes, and safety mechanisms.
Hoists and conveyors follow similar measurement principles as lifts, maintaining consistency in project planning.

General Considerations

Essential to perform thorough testing and commissioning.
Necessary documentation includes drawings, manuals, and identification markers.
Collaboration with electrical work and other trades is vital for cohesive installations.
