INTRODUCTION
This comprehensive assessment evaluates the knowledge and skills required for the Louisiana Rigging,
House Moving, Wrecking, and Dismantling contractor license. Candidates must demonstrate
competency in foundational rigging theory, applied hoisting techniques, structural moving procedures,
and demolition methodologies. The examination emphasizes real-world application, safety awareness,
regulatory compliance, and professional decision-making. Questions include direct knowledge
assessments and scenario-based problems requiring critical thinking and practical judgment. The
assessment structure mirrors the closed-book format used by the Louisiana State Licensing Board for
Contractors, with multiple-choice questions covering technical concepts, ethical obligations, and
workplace situations designed to verify readiness for licensed practice.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of a rigging plan before commencing a lifting operation?
A. To establish a schedule for equipment mobilization
B. To ensure loads are lifted safely and within equipment limits
C. To calculate the total cost of the lifting operation
D. To assign personnel to specific shifts
🟢 B. To ensure loads are lifted safely and within equipment limits
🔴 Explanation: A rigging plan organizes the safe execution of a lift by identifying load weight, rigging
configurations, equipment capacities, and hazard controls. Its central purpose is preventing overload
and maintaining load control throughout the operation.
Question 2
,Which document is typically required before any demolition work begins on a commercial structure
exceeding $50,000 in Louisiana?
A. Sales contract
B. Warranty bond
C. Demolition permit
D. Equipment lease agreement
🟢 C. Demolition permit
🔴 Explanation: Louisiana law requires licensed contractors to obtain appropriate permits before
demolition. For commercial structures exceeding $50,000, the rigging, house moving, wrecking, and
dismantling classification is required, and a demolition permit ensures regulatory compliance.
Question 3
What does the term “safe working load” (SWL) represent for lifting equipment?
A. The maximum load at which equipment fails
B. The load at which the safety factor is eliminated
C. The maximum load allowed under normal conditions
D. Twice the rated capacity of the equipment
🟢 C. The maximum load allowed under normal conditions
🔴 Explanation: SWL is the maximum mass or force that lifting equipment is designed to support
under normal service conditions. It incorporates an appropriate safety factor and must never be
exceeded during operations.
Question 4
A crane is lifting a load using two slings configured at a 30-degree angle from horizontal. What effect
does this low angle have on sling tension?
A. Sling tension decreases compared to vertical lift
B. Sling tension remains the same as vertical lift
C. Sling tension increases significantly compared to vertical lift
D. Sling tension is irrelevant at angles below 45 degrees
🟢 C. Sling tension increases significantly compared to vertical lift
🔴 Explanation: As the sling angle decreases from vertical, the tension on each sling leg increases
because the load force is distributed through a smaller vertical component. At 30 degrees, tension is
substantially higher than at 90 degrees. Angles below 30 degrees are not recommended.
Question 5
Before a house moving operation, what must be verified regarding utility services?
,A. That utility meters are painted and labeled
B. That all gas, electric, water, and sewer services are disconnected and verified safe
C. That utility companies have been billed for service
D. That utilities remain operational for lighting
🟢 B. That all gas, electric, water, and sewer services are disconnected and verified safe
🔴 Explanation: Disconnecting utilities prevents fire, explosion, electrocution, and flooding hazards
during house moving. All service lines must be shut off, capped, or otherwise controlled outside the
building line before work begins.
Question 6
What is the primary function of outriggers on a mobile crane?
A. To increase travel speed on the highway
B. To extend the boom length
C. To provide stability and prevent tipping during lifting
D. To reduce fuel consumption
🟢 C. To provide stability and prevent tipping during lifting
🔴 Explanation: Outriggers distribute the crane's weight and load forces over a larger ground area,
increasing the effective base of support and preventing overturning. They must be fully extended and
properly supported before lifting.
Question 7
In demolition sequencing, which structural elements should generally be removed first?
A. Foundation footings
B. Load-bearing walls
C. Non-structural elements and interior finishes
D. Roof support beams
🟢 C. Non-structural elements and interior finishes
🔴 Explanation: Demolition proceeds from non-structural to structural elements, typically top-down.
Removing interior finishes and non-load-bearing components first reduces hazards and allows
controlled dismantling of primary structural members.
Question 8
What is the primary hazard associated with crane operation near energized power lines?
A. Increased fuel consumption
B. Electrocution from direct or indirect contact
C. Radio signal interference
D. Hydraulic fluid contamination
, 🟢 B. Electrocution from direct or indirect contact
🔴 Explanation: Electricity can arc across gaps, so maintaining required clearances is essential. Contact
between the crane, load, rigging, or personnel and energized conductors can cause fatal electrocution.
OSHA requires minimum approach distances.
Question 9
When is a demolition engineering survey required under OSHA regulations?
A. Only for structures over five stories
B. Before permitting employees to start demolition operations
C. Only when explosives will be used
D. After demolition is complete
🟢 B. Before permitting employees to start demolition operations
🔴 Explanation: OSHA 1926.850(a) requires that prior to permitting employees to start demolition
operations, an engineering survey be made by a competent person to determine the condition of the
framing, floors, and walls, and the possibility of unplanned collapse.
Question 10
What is the purpose of cribbing during house raising operations?
A. To serve as permanent foundation material
B. To provide stable, temporary support while jacks lift the structure
C. To decorate the site perimeter
D. To anchor the structure during transport
🟢 B. To provide stable, temporary support while jacks lift the structure
🔴 Explanation: Cribbing creates a stable platform that distributes loads while the house is lifted. It
provides temporary support at incremental heights as jacks raise the structure and must be set on a
level and firm foundation.
Question 11
What type of hitch is most likely to damage a fragile load due to compression?
A. Basket hitch
B. Vertical hitch
C. Choker hitch
D. Bridle hitch
🟢 C. Choker hitch
🔴 Explanation: A choker hitch tightens around the load as tension is applied, which can crush or
deform fragile materials. Basket hitches distribute load more gently and are preferred for delicate
items.
