This report presents the development highlights for the BiOS app completed in 2018-2019 by FPI. An updated methodology is defined to help FLNRORD fully integrate the BiOS app data point collection into the Forest BioGis web platform. A visual roadside pile volume estimator was also developed and implemented into the BiOS app. This visual estimator will need to be calibrated and further developed with roadside pile recovery trials performed in various BC conditions. Finally, a four-year development plan is proposed to have a fully validated set of tools in the Forest BioGIS web platform and the BiOS app.
In order to provide bridge designers with better information, International Forest Products Limited (Interfor) asked the Forest Engineering Resarach Institute of Canada (FERIC) to evaluate the bending strength and stiffness of log stringers used for constructing bridges on forest roads in coastal British Columbia. Given the lack of definitive standards for testing this material, FERIC developed a field-based test procedure and designed a test facility for destructive testing of full-size, whole-log stringers obtained from second-growth stands. Sixteen coastal Douglas-fir and twelve western hemlock logs were tested in 2003. This report describes the test procedure and methods of analysis, presents the log bending strength and stiffness results, and makes recommendations regarding future testing.
FERIC monitored the hydraulic system temperatures of a sample of delimbers and graders operating in the boreal forest of northern Ontario to obtain typical performance data during both summer and winter. The goal of the study was to permit a comparison of the performance of seasonal and year-round hydraulic oils. The report notes mechanical design problems with typical systems, and compares the advantages and disadvantages of the two types of oil.
Contamination of hog fuel along the supply chain was observed at Skookumchuk. FPInnovations recommends that the number of times hog fuel is moved be minimized, that operators be trained in correct handling procedures, that a penalty/reward system be instituted to habituate proper handling procedures, that cross logs be used beneath log decks, that hog fuel storage surfaces be paved or frozen, and that hog fuel produced in the field be ground directly into chip vans.
