What you'll learn
- Distinguish the roles of licensed land surveyors, layout surveyors and field engineers, and explain horizontal and vertical datums, NAD83, State Plane coordinates, NAVD88 and scale factors
- Classify measurement errors, explain accuracy and precision, and apply checks, redundancy and closure to construction survey work
- Correct taped and electronic distances and reduce, check and adjust differential level runs, including the two-peg test
- Measure and convert angles, bearings and azimuths, set up and orient a total station, and compute, check and adjust a closed traverse
- Explain how RTK and network GNSS work, what limits their accuracy, how site calibration ties them to project coordinates, and how scanning and drones are used
- Use coordinate geometry to compute inverses, layout angles and distances, stationing and offsets, and the elements and layout of horizontal circular curves
- Plan building layout from protected control, check square with diagonals, set foundations and anchor bolts, and transfer control and elevations up a structure
- Express slopes and grades, compute pipe inverts and vertical curve elevations, and read and write grade and slope stakes
- Calculate earthwork volumes by average end area, prismoidal and grid methods, and convert between bank, loose and compacted volumes
- Build and interpret a mass haul diagram, and decide between hauling, wasting and borrowing using freehaul, overhaul and the economic haul limit
- Select excavating, hauling, grading and compaction equipment, and account for rolling resistance, grade resistance, traction and payload limits
- Estimate equipment production, balance fleets, calculate owning and operating costs and unit costs, and plan machine control and site technology with appropriate checks
