The existing counterweight on the 7B conveyor had a winch system with inadequate lug connections and was rigged at an improper angle, which created structural integrity issues. Bowman prepared an economic trade-off study and general arrangements for counterweight lifting methods.
The client was looking for a safer and more efficient way to transfer ore to the main course ore bin. Bowman produced general arrangements and mechanical drawings for the project.
Project objective was to evaluate existing capacity of ceiling beams for trolley and hoist system designed to remove and install belt feeder motors to a roof opening area. Bowman provided a load rating and lifting plan for the belt feeder motors.
Thomas Jefferson’s home, Monticello, was a working, 5,000-acre plantation that was home to Jefferson and hundreds of other people. In 2022, the Monticello archaeology team contracted our team to acquire 30 points per square meter (ppm) lidar of the original 5,000-acre to identify unseen traces of past agricultural land use.
Bowman provided engineering services for a construction drawing package for access road grading and drainage improvements. The haul roads were severely damage during storm events so collection, conveyance channels, sediment traps and culverts were designed to manage a 25-year, 24-hour storm event.
Based on previous wash settler design experience, Bowman was uniquely qualified to do a feasibility study (FS) design for a new solvent extraction (SX) plant at a different operation for the Sierrita Mine. The project required a closely coordinated team of process, mechanical, civil, structural and electrical engineers.
Bowman provided construction engineering services. Because of changes in the planned use of the AB-BC Tailings storage facility, the diameter of the slurry distribution pipes were reduced from 18” to 12”. This and other changes were implemented in the pump set ups. These changes resulted in overall improved decant system efficiency.
Bowman geologists/hydrogeologists were responsible for the implementation of a groundwater investigation relative to a proposed quarry deepening.
Bowman completed a drainage basin analysis and groundwater study to evaluate the impact mining would have on the regional watershed within the Adirondack Mountains.
