A Prince George company is donating three pieces of survey equipment to CNC’s carpentry department.
McElhanney Consulting Services Ltd. is giving the Prince George campus two Sokkisha TM-20E and one TM-10E theodolites, which are instruments used in surveying to measure horizontal and vertical angles to the highest degree of accuracy.
“These instruments would be used anywhere from picking up ground features to laying out foundations and walls on a construction site,” said Bill Cheung, McElhanney branch manager. “The survey instruments are a great learning tool as the principles of survey measurement are very clear and easily taught with this kind of basic gear.”
Newer instruments feature electronic distance measurement built right into the instrument. These instruments, which are from the 1980s, do not have that capability, but are still useful. Distances were measured using tape measures or chains.
"A manual theodolite is good for showing a student the step by step process of angular layout. Digital theodolites process the information automatically and do not allow students quite the same opportunity to understand this process," said Phil Missellbrook, toolroom technician with CNC’s Carpentry Department.
“We use these manual instruments in the classroom all the time, but they are no longer manufactured and we needed more for our students. The only way to obtain them was through donation.
That’s when McElhanney stepped in.
“We're supportive of technical education in our own communities,” said Cheung. “When Phil told us about the need for some basic theodolites for the carpentry department, McElhanney's Prince George and Vancouver offices looked through their equipment to see if there was anything suitable that we were not using anymore on a full-time basis.”
The total value of the theodolites is about $1,600.
