Drilled Shaft Foundation Inspection is a stand-alone course developed to provide a basis for local, regional, or national qualification of drilled shaft foundation inspectors. The goal of this course is to provide inspectors with practical knowledge and standard industry practices for the inspection of drilled shaft foundation construction. A 2-hour qualification exam is administered on the third day of the course.
The course follows recommended FHWA specifications and practices for drilled shaft construction but may be modified to follow local agency specifications and practices.
NOTE: All participants should be advised by the local coordinator/session host that they are encouraged to complete NHI 132070B Drilled Shaft Inspector Tutorial (WBT).
Upon completion of the course, participants will be able to:
Identify and understand the role and duties of the inspector
Recognize key inspection elements of the contract documents
Identify proper communication and coordination with the engineer and contractor
Interpret and verify contractor compliance with items in the drilled shaft installation plan
Recognize and identify drilled shaft construction equipment and tools
Perform visual field verification of soil/rock material for comparison to supplied soil boring data/logs
Calculate percent recovery and rock quality designation (RQD)
Recognize and identify the various types of drilled shaft construction
Perform inspection of drilled shaft excavations for compliance with plans, construction tolerances, and cleanliness
Verify reinforcing cage construction compliance including side spacers and cross-hole sonic logging (CSL) tubes
Determine concrete volumes for theoretical shafts and develop concrete curves
Identify shaft "concreting" irregularities
Perform calculations for volume, area, circumference, and elevation
Locate, explain, and apply applicable FHWA, AASHTO, and State DOT specifications relating to compliance
The target audience for this course includes agency and consultant personnel who inspect foundations or major structures. In addition, project management and construction engineers in charge of drilled shaft construction inspection are encouraged to attend. This course is designed to be most beneficial to foundation inspectors who are responsible for inspecting drilled shafts during construction.
