Course Description

Provides a collaborative learning framework in which learners practice the basic concepts of construction surveying. Includes set up and use of auto level, total station, leveling rod and steel tape. Also included are field note assembly and interpretation, and elevation and distance measuring techniques. Vertical and horizontal angle calculations are also covered. Includes grid method for generating contour maps. Prerequisites: Prior completion of BCT 104 or instructor permission. Audit available.

Intended Outcomes for the course

To carry out building construction tasks requiring reliable differential leveling, calculation of horizontal and vertical angles and generation and interpretation of contour maps.

Clearly and concisely document fieldwork, in a Transit Notebook

Outcome Assessment Strategies

1. Complete 4 " Field Labs" in which learners will work collaboratively with at least one other student to gather the information necessary to generate a plot plan. Learners will perform accurate measuring, differential leveling, turning of horizontal and vertical angles, and collection of contour data.
2. Learners will sketch a plot plan complete with property corner elevations, interior angles, bearings, and title block.
3. Learners will individually successfully complete two written "Mastery Projects" covering the concepts, themes and issues of the course.
