Summary

• Description:

  The PDF document comprises Grade 10 Building Construction Strand 4 Building Services Notes. The MS Word version (editable) is also available upon your request.

  It covers the following strands and sub-strands:

  • Strand 4.0: Building Services
    • Sub-strand 4.1: Plumbing Tools and Equipment
      • Identification of Plumbing Tools: Categorization into Holding tools (Pipe Vice, Bench Vice), Cutting tools (Pipe Cutter, Hacksaw, Reamers, Files), Fitting tools (Pipe Wrench, Adjustable Spanner, Basin Wrench, Pliers), Threading tools (Die Stock, Taps), and Bending tools (Pipe Bender, Bending Spring).
      • Safety Measures: Critical precautions including using the right tool for the job, checking tool condition, securing work pieces, heat safety, and using PPE (Boots, Goggles, Gloves).
      • Procedure for Using Plumbing Tools: A step-by-step practical scenario for cutting and threading a GI pipe, covering measuring, securing, cutting, reaming, and threading.
      • Care and Maintenance: Best practices for cleaning, oiling/lubrication, sharpening cutting wheels, and proper storage to prevent damage.
      • Importance of Tools: How proper tools impact efficiency, quality of work, safety, and professional reputation.
    • Sub-strand 4.2: Plumbing Materials
      • Classification of Plumbing Materials: Detailed breakdown of Metallic pipes (Galvanized Iron classes A/B/C, Copper, Cast Iron), Plastic/Polymer pipes (PVC/uPVC, PPR, HDPE, CPVC), and Ceramic/Concrete pipes.
      • Properties of Plumbing Materials: Key physical and chemical properties including Corrosion Resistance, Thermal Conductivity, Malleability/Ductility, Coefficient of Expansion, and Roughness (Hydraulic Flow).
      • Selection of Materials: Guidelines for choosing materials for specific scenarios: Underground Mains (HDPE), Hot Water Distribution (PPR/Copper), Drainage (uPVC), and Outdoor/Exposed lines (GI).
      • Importance of Materials: Impact on health (potability), economic efficiency (lifecycle costs), and environmental sustainability.
    • Sub-strand 4.3: Pipework
      • Types of Pipes and Fittings: The "vocabulary" of pipework including Elbows (90, 45, Street), Tees (Equal, Reducing), Sockets/Couplers, Unions, Nipples (Barrel, Hex), Plugs, Caps, and Bushings.
      • Preparing Pipe Joints: Techniques for different materials: Threaded Joints for GI (using Hemp/Boss White or PTFE Tape), Thermal Fusion for PPR, Solvent Weld for uPVC, and Compression Joints for HDPE/Copper.
      • Performing Pipe Bending: The science of bending (Tension vs. Compression) and methods including Machine Bending, Spring Bending (for conduit), and Sand/Hot Bending.
      • Safety When Performing Pipework: Managing risks related to heat (fusion machines/torches), chemicals (solvent cement fumes), and sharp edges.
      • Importance of Proper Pipework: Ensuring hydraulic efficiency, leak prevention, system maintainability, aesthetics, and noise reduction.
