Rationale 2027 Q&A| Instant Download Pdf
This is an original practice exam for studying demolition and wrecking
principles, not an official Arizona examination. Always follow
applicable codes, permits, site-specific engineering plans, and current
safety requirements.
Section 1: Demolition Planning and Site Assessment
1. What is the primary purpose of conducting a pre-demolition
survey?
a. To determine the resale value of salvage materials
b. To estimate the number of workers required for cleanup
c. To identify structural conditions, hazardous materials, utilities, and
demolition hazards
,d. To establish the final landscaping requirements
Rationale: A pre-demolition survey identifies structural characteristics,
hazardous substances, utility connections, adjacent structures, and
potential hazards. This information supports safe demolition
sequencing, appropriate equipment selection, regulatory compliance,
and protection of workers and the public.
2. Before beginning demolition of an existing commercial building,
what should the contractor do regarding permits?
a. Begin work after notifying the neighboring property owners
b. Obtain the required demolition permits and approvals from the
appropriate authorities
c. Obtain approval only if the building is more than two stories tall
d. Begin interior demolition while waiting for all permits
Rationale: Demolition work must comply with applicable permitting
and approval requirements. Depending on the project, these may
include building department permits, environmental approvals, utility
clearances, and other authorizations. Starting without required
approvals can result in stop-work orders, penalties, and unsafe
conditions.
,3. Which document provides important information about a building's
original structural design?
a. The contractor's daily time sheet
b. The equipment maintenance log
c. The original structural drawings and available building plans
d. The material disposal receipt
Rationale: Structural drawings and building plans can identify load-
bearing walls, columns, beams, foundations, and structural
connections. However, drawings must be verified against actual field
conditions because renovations, deterioration, and undocumented
alterations may have changed the structure.
4. Why must a demolition contractor investigate previous renovations
before beginning work?
a. Renovations always make a building easier to demolish
b. Renovations eliminate the need for structural analysis
c. Renovations determine the contractor's insurance premium
exclusively
d. Alterations may have changed load paths, concealed hazards, or
weakened structural components
, Rationale: Previous renovations may have removed structural
supports, added loads, concealed utilities, or introduced materials
such as asbestos. Identifying these changes helps the contractor
develop a safe demolition sequence and avoid unexpected structural
failure.
5. What is the principal purpose of a demolition sequence?
a. To maximize the amount of debris produced each day
b. To establish a controlled order of removal that maintains stability
and worker safety
c. To ensure that exterior walls are always demolished first
d. To eliminate the need for equipment inspections
Rationale: A demolition sequence specifies the order in which
structural and nonstructural components are removed. A properly
engineered or otherwise appropriately developed sequence prevents
premature collapse, controls falling materials, and ensures that
remaining portions of the building remain stable.
6. Which condition should be investigated before demolishing a wall
that may be load-bearing?
a. The color of the wall's paint
