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.
This course isn't currently offered through BCIT Part-time Studies. Please check back next term or subscribe to receive email updates.
Upon successful completion of this course, the student will be able to:
Appreciate the role of Scaling in BC:
Evolution of scaling practices
BC Log rule
Piece scaling system
Weight scaling system.
Use a Scale Stick:
Measure slab ends
Use geometry to calculate areas and volumes:
Frustums (Smalian's formula).
Identify common Coastal log species:
Calculate deductions for common defects:
Understand timber grading by 'sorts' and associate end products:
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.
Effective as of Spring/Summer 2017
