1. Which document most directly establishes the required structural
steel member sizes, connection details, material specifications, and
design loads for a structural steel project in Colorado?
A. The contractor's equipment inventory
B. The project schedule
C. The approved structural drawings and specifications
D. The manufacturer's sales brochure
The approved structural drawings and specifications establish the
engineered requirements for structural members, connections,
materials, and construction details. The contractor must construct the
work in accordance with the approved documents and applicable
adopted codes.
2. Which organization publishes the Specification for Structural Steel
Buildings commonly used for the design and construction of
structural steel building systems in the United States?
,A. ASTM International
B. OSHA
C. American Institute of Steel Construction (AISC)
D. American Society of Mechanical Engineers (ASME)
AISC publishes widely adopted specifications, manuals, and standards
governing structural steel design, fabrication, and erection. AISC
requirements are commonly incorporated into project specifications and
building-code provisions.
3. A structural steel contractor receives a drawing showing a beam
connection that differs from the connection details in the project
specifications. What should the contractor do first?
A. Use whichever connection is less expensive
B. Fabricate both connections and allow the inspector to choose
C. Request clarification through the appropriate design or project-
management process
D. Select the connection most commonly used by the contractor
Conflicting construction documents should be resolved through the
architect, engineer, or authorized project-management process before
fabrication or installation. The contractor should not independently alter
engineered structural requirements.
4. Which ASTM specification is commonly associated with carbon
structural steel shapes, plates, and bars used in general structural
applications?
,A. ASTM A53
B. ASTM A106
C. ASTM A36
D. ASTM B88
ASTM A36 is a widely recognized specification for carbon structural steel
used in plates, bars, and structural shapes. The actual required material
grade must always be verified against the project specifications.
5. Why is material traceability important when fabricating structural
steel?
A. It determines the contractor's labor rate
B. It eliminates the need for welding procedures
C. It allows structural materials to be identified and verified against
specified grades and required documentation
D. It guarantees that the steel will never corrode
Material traceability allows the contractor and quality-control personnel
to verify that the steel incorporated into the structure corresponds to
the specified material grade and applicable certification requirements.
6. What document commonly provides certified information about the
chemical composition and mechanical properties of structural steel?
A. Daily work report
B. Delivery ticket alone
C. Mill test report (MTR)
D. Equipment inspection tag
, A mill test report documents important material properties and
chemical composition and can be used to verify compliance with the
specified steel grade. Proper identification and traceability must be
maintained from receipt through fabrication.
7. Before erecting structural steel, what is the most important reason
for verifying anchor-bolt locations?
A. Anchor bolts determine the color of the steel coating
B. Anchor bolts are used only to support temporary fencing
C. Incorrect anchor-bolt locations can prevent columns and base plates
from being properly installed
D. Anchor bolts determine the welding electrode classification
Column base plates depend on properly located and aligned anchor
bolts. Significant errors can cause fit-up problems, require engineered
corrections, delay erection, or compromise the intended structural
connection.
8. What is the primary purpose of a column base plate?
A. To prevent all thermal expansion
B. To provide a decorative finish
C. To transfer column loads to the supporting foundation or structural
element
D. To replace all anchor bolts
A column base plate distributes forces from the steel column into the
supporting concrete or structural foundation. Its dimensions, thickness,
