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.
