COURSE SYLLABUS
BONDED (MULTI-STRAND AND BAR) POST-TENSIONING
Course Description:
This course is designed to provide the Iron Worker student with training in bonded post-tensioning systems, including bar and multi-strand systems. The course covers principles and theories, system components, tools and equipment, safety, unloading, handling, storage, installation, stressing, grouting, and finishing for all types of systems.
Course Objective:
The objective of this course is to enable a student to safely install, stress, and grout bonded post-tensioned reinforcing systems.
Learning Outcomes:
Upon successful completion of this course, the student will be able to apply the following in the field:
· Apply the principles and theories of post-tensioning and be able to identify the components of multi-strand and bar tendon systems.
· Use the tools, equipment and procedures to unload, handle, layout, install, and stress each type of bonded post-tensioning system.
· Use the tools, equipment and procedures to grout and finish each type of bonded post-tensioning system.
· Troubleshoot and repair post-tensioning systems, stressing equipment, and grouting equipment on the job.
Target Audience:
This course is designed for apprentices and journeymen.
Length of Course:
This course is designed to be offered during a total of 30 hours – 20 hours of classroom instruction and 10 hours of hands-on lab or shop training. It is recommended that classroom and hands-on lab or shop sessions be combined where appropriate. For example, the instructor may spend 90 minutes in lecture in the classroom followed by 90 minutes in the lab or shop. This means the course may consist of 10 3-hour sessions. When appropriate, more class sessions may be held for shorter periods of time in order to provide the student with sufficient opportunities to learn the content.
Course sessions may be conducted during evenings in blocks of 3 or 4 hours or may be conducted during all day sessions. Given the time required for students to master these skills, it is recommended that all day courses include classroom sessions of no more than a 3 to 4-hour block in the morning and a 3 to 4-hour block in the afternoon.
Lab or shop sessions may be scheduled for as little time as 1 hour and may be as long as 6 hours (with breaks).
Location of the Course:
All courses will be held at the facilities used by the local union. Lab or shop activities may be held in an inside work area and/or may be held in an outside work area.
Instructor Information:
The instructor for this course is a journeyman Iron Worker with experience working with bonded post-tensioning systems in concrete structures, who is able to perform all of the skills and who has been trained as an instructor.
Course Materials:
· Bonded Post-tensioning Reference Manual
· Bonded Post-tensioning Student Workbook and Drawings
· Bonded Post-tensioning Instructor Guide (for instructors only)
· Bonded Post-tensioning Instructor DVD
· Assignment Sheets (in the Student Workbook)
· Job Sheets (in the Student Workbook)
· Tests (in the Instructor Guide)
A Word about Safety
The importance of safety will be addressed and reinforced in all hands-on activities in the classroom, in the shop, and on the job site.
Course Assignments:
There will be assignments and students will complete these assignment sheets prior to and/or during course sessions as determined by the instructor. Job skills will be completed as part of appropriate units. Most job skills will be completed in the lab or shop area and/or outside in a work area.
Course Grading Criteria:
To successfully complete this course, the student must complete all of the assignment sheets, demonstrate the required skills in the lab or shop, and pass the knowledge tests.
Course Attendance:
All course sessions are mandatory and while missed time can be made up, missing a course session will affect your ability to successfully complete this course. Speak with the instructor to arrange make-up time if necessary.
Course Schedule:
NOTE: The following Course Schedule is set up for blocks or sessions 3 hours in length. If your course sessions are more or less than 3 hours, you will need to adjust the number of sessions accordingly.
