MASSACHUSETTS CONSTRUCTION
SUPERVISOR LICENSE (CSL) PRACTICE EXAM |
QUESTIONS AND VERIFIED ANSWERS |
ALREADY GRADED A+ | Plus RATIONALES (3
SECTIONS)
Course Name: Massachusetts Construction Supervisor License (CSL)
Preparatory Course
Subject: Massachusetts Building Code (780 CMR 10th Edition),
Construction Safety, and Supervisory Practice
Section 1: Questions 1–50
1. A 22-year-old carpentry apprentice with two years of documented
W-2 field experience and a four-year vocational high school diploma in
building construction applies to take the Unrestricted CSL exam.
Under the BBRS administrative rules, what is the applicant's eligibility
status?
A. Ineligible, because a vocational high school education does not count
towards the required 36 months of field experience.
B. Eligible, because the four-year vocational diploma satisfies one year
of experience, combining with the W-2 experience to meet the 36-
month requirement.
C. Ineligible, because all 36 months of experience must be documented
,Page 2 of 55
via W-2s or a licensed engineer's attestation.
D. Eligible, because the applicant is over 18 and has at least two years of
experience, which is sufficient for the Unrestricted exam.
❖ Rationale: The administrative code explicitly allows a three- or
four-year vocational high school program in building construction
to be deemed equivalent to one year of work experience. Two
years of paid experience plus the one-year education credit
satisfies the 36-month requirement for both Restricted and
Unrestricted applications.
2. A construction supervisor holds an Unrestricted CSL and is asked to
oversee the construction of a new commercial retail space with an
enclosed volume of 32,000 cubic feet. Which of the following
accurately describes the supervisor's authority?
A. The supervisor is prohibited from supervising this project because it
is a commercial occupancy.
B. The supervisor may supervise this project, as an Unrestricted CSL
permits supervision of any use group up to 35,000 cubic feet.
C. The supervisor may only supervise the structural elements but must
hire a commercial contractor for finishing work.
D. The supervisor is allowed to supervise the project only if it is a one-
or two-family dwelling.
❖ Rationale: The scope of an Unrestricted Construction Supervisor
License includes buildings of any use group which contain less than
35,000 cubic feet of enclosed space, in addition to one- and two-
family dwellings of any size.
3. According to the 10th Edition of the Massachusetts State Building
Code (780 CMR), what is the minimum required compressive strength
,Page 3 of 55
for concrete used in footings for a single-family home?
A. 2,000 psi
B. 3,500 psi
C. 2,500 psi
D. 4,000 psi
❖ Rationale: The 10th Edition of the Massachusetts State Building
Code requires a minimum compressive strength of 2,500 psi for
concrete footings supporting one- and two-family dwellings.
4. A project manager proposes substituting a cheaper, non-compliant
material in a fire-resistance-rated wall assembly, arguing that the
owner has signed a waiver accepting liability. What is the construction
supervisor's best course of action?
A. Approve the substitution if it reduces costs for the owner.
B. Approve it, as the owner's signed waiver absolves the supervisor of
liability.
C. Reject the substitution unless an approved code-compliant
assembly or equivalency is established through the proper process.
D. Allow the substitution, as fire-resistance requirements are only
applicable after a Certificate of Occupancy is issued.
❖ Rationale: Required fire-resistance ratings are life-safety
requirements that cannot be eliminated by a cheaper material or
owner waiver. Any alternate assembly must satisfy the applicable
code and approval requirements.
5. What is the primary purpose of the Massachusetts State Building
Code (780 CMR)?
A. To increase construction costs for the benefit of the insurance
industry.
, Page 4 of 55
B. To ensure public safety, health, and welfare through minimum
standards for building design and construction.
C. To promote the construction industry by maximizing profit margins.
D. To provide a framework for local building officials to collect permit
fees.
❖ Rationale: The primary purpose of the building code is to protect
the public safety, health, and welfare through regulations
governing the design, construction, and maintenance of buildings.
6. A construction supervisor discovers that ordinary electroplated
fasteners have been used to install a pressure-treated wood deck.
What should the supervisor do?
A. Accept the installation if the fasteners are the same diameter as the
specified ones.
B. Accept the work if the deck appears to be stable under a visual
inspection.
C. Require the use of hot-dipped galvanized fasteners or other
approved corrosion-resistant connectors.
D. Cover the fasteners with paint to protect them from moisture.
❖ Rationale: Modern preservative-treated lumber can be corrosive
to incompatible metals. Corrosion-resistant fasteners (such as hot-
dipped galvanized) must be used to maintain structural
performance and prevent premature failure.
7. In Massachusetts, residential stair risers are limited to a maximum
height of:
A. 8¼ inches
B. 7¾ inches
