BCTI 120 - Introduction to Heavy Highway Construction

1. Investigate careers, equipment, and processes used in the construction of highways and bridges.
2. Identify the types of heavy equipment, utility equipment, and cranes used in the construction of bridges and highways.
3. Examine the safety hazards and precautions associated with construction of highways and bridges with emphasis on the importance of following safety procedures in order to prevent accidents and injuries associated with working in hazardous places/conditions.
4. Analyze the signs, signals, and barricades found on various job sites including highway work-zone safety requirements.
5. Describe soil classification systems and explain how shrink and swell factors affect equipment selection; also discuss how soil conditions affect equipment performance and explain techniques for working with various types of soils.
6. Examine the methods used to set and interpret grade stakes. List methods for controlling surface water and ground water on a job site, as well as the layout of foundations and laying of pipe.
7. Apply basic math skills required for site excavation work including methods and practice in calculating the areas and volumes of various geometric shapes, as well as formulas and methods used to calculate cut and fill requirements of a job.
8. Explain how to read site plans to calculate cut and fill requirements; interpret both roadway and construction site drawings used for excavation and grading work.
9. Attain readiness to take the first half of the NCCER Heavy Highway Construction Level 1 certification exams.
