RENR 1601 - Introduction to Log Scaling (Coastal)

Renewable Resources Part-time Studies Course

School of Construction and the Environment

Course Details

This introductory course provides an overview of coastal log scaling. The course is designed to 1) provide the basic knowledge required to pursue further training necessary to obtain a Provincial Coastal Log Scaling licence, and 2) provide background knowledge for people who are working in a related field. A statement of completion (level 1 Log Scaling) will be issued upon successful completion. Included are practical skills for log measurements, volume calculations and the value grading of coastal log species based on the statutory grading system. The scaling equipment is provided, however the student must have caulk boots.

Prerequisite(s)

None. For further course information contact Dina Patterson at 604-432-8539.

    • Piece scaling system
    • Weight scaling system.
  • Use a Scale Stick:
    • Measure diameters,
    • Measure slab ends
    • Calculate volumes
    • Compute deductions.
  • Use geometry to calculate areas and volumes:
    • Circles
    • Squares/rectangles
    • Cylinders

    • Lumber logs
    • Peelers
    • Shingle grades
    • Sawlogs
    • Utility.
  • Apply Timber grading procedures:
    • Assess gross and net requirements to meet the grade rule: top diameters, lengths, merchantability, clear.
    • Assess quality requirements to make the grade: knots, spiral grain (twist), grain density, stain.
    • Assess product recoverability and apply grade reduction: fractures and fibre separations; bark seams; sweep, crook and pistol grip; rot, hole, char and missing wood.
