BCTI 122 - Heavy Highway Construction Part 1

1. Discuss the process of planning and executing earthmoving activities on various types of construction projects. Explain the use of heavy equipment such as bulldozers, scrapers, excavators, and loaders.
2. Examine common types of equipment and instruments used for finish grading; materials and methods used to stabilize soils and control soil erosion; and finishing and grading methods used for various applications.
3. Examine working in and around excavations, particularly in preparing building foundations. Describe types and bearing capacities of soils; procedures used in shoring, shielding, and sloping trenches and excavations; trenching safety requirements, including recognition of unsafe conditions; and mitigation of groundwater and rock when excavating foundations.
4. Describe the operation of plants used to manufacture concrete and asphalt paving and discuss the different types of aggregates.
5. Analyze paving operations, paving equipment, recycling processes, and quality control requirements for both concrete and hot-mix asphalt paving.
6. Describe elevated decks and formwork systems and methods used in their construction. Examine joist, pan, beam and slab, flat slab, composite slab, and specialty form systems and discuss instructions for the use of flying decks, as well as shoring and reshoring systems.
7. Discuss the applications and construction methods for types of forming and form hardware systems for walls, columns, and stairs, as well as slip and climbing forms. Describe the assembly, erection, and stripping of gang forms.
8. Attain readiness to take the first half of the NCCER Heavy Highway Construction Level 2 certification exams.
