1. What is the primary purpose of a tilt-up concrete panel’s lifting
inserts?
a. To provide permanent structural reinforcement
b. To anchor interior finishes
c. To provide attachment points for lifting equipment
d. To prevent concrete shrinkage
Answer: c. To provide attachment points for lifting equipment
Rationale: Lifting inserts are specifically designed to transfer lifting
forces from the panel to the lifting hardware. Their location, capacity,
embedment, and installation must be coordinated with the
engineered erection plan. They are not simply general-purpose
reinforcing components.
, 2. Before casting a tilt-up panel, what should be verified regarding
the casting surface?
a. It is intentionally rough and unsealed
b. It is clean, properly prepared, and suitable for panel release
c. It contains standing water
d. It is covered with loose aggregate
Answer: b. It is clean, properly prepared, and suitable for panel
release
Rationale: The casting slab serves as the form surface for tilt-up
panels. Proper preparation helps prevent unwanted bonding and
surface defects and allows the panel to be safely lifted after curing.
Dirt, debris, excessive moisture, or unsuitable release-agent
application can compromise the finished panel.
3. Which factor is particularly important when determining when a
tilt-up panel can be lifted?
a. Paint color
b. Concrete maturity and required strength
c. Interior wall finish
d. Roofing material
Answer: b. Concrete maturity and required strength
,Rationale: A panel must develop sufficient concrete strength before
lifting so that it can resist stresses created during handling. The
required strength should come from the project’s engineered erection
requirements rather than being assumed solely from elapsed time.
4. What is the main function of reinforcing steel in a tilt-up concrete
panel?
a. To eliminate the need for concrete strength
b. To resist tensile and other design forces in the panel
c. To make the panel easier to lift
d. To replace lifting inserts
Answer: b. To resist tensile and other design forces in the panel
Rationale: Reinforcement helps the panel resist tensile stresses,
bending, cracking, and other structural demands identified by the
design. Reinforcement does not replace lifting inserts or eliminate the
need for properly designed concrete.
5. Which document should provide the engineered requirements for
lifting a tilt-up panel?
a. The landscaping plan
b. The architectural color schedule
, c. The engineered erection or lifting plan
d. The finish-paint schedule
Answer: c. The engineered erection or lifting plan
Rationale: Tilt-up erection involves temporary conditions and lifting
forces that may differ significantly from the panel’s final service
condition. The engineered erection plan identifies lifting points,
equipment requirements, bracing, sequencing, and other critical
temporary conditions.
6. What is the purpose of temporary bracing after a tilt-up panel is
erected?
a. To provide temporary stability until the permanent structural system
is effective
b. To increase the panel's decorative value
c. To replace permanent connections
d. To reduce concrete curing time
Answer: a. To provide temporary stability until the permanent
structural system is effective
Rationale: Newly erected panels can be vulnerable to wind and other
lateral forces before the building’s permanent structural system is
fully connected. Temporary braces maintain stability during this
