1. A restoration contractor is preparing a bid for a large commercial loss involving fire damage
to a mixed-use building. The building owner requests that the contractor provide a guaranteed
maximum price (GMP) and a detailed line-item budget, but the contractor's initial survey is
incomplete because the roof is still partially unstable. Which action BEST aligns with both
ethical standards and prudent business management?
A. Provide the GMP based on a worst-case scenario and add a large contingency to protect the contractor's
margin.
B. Decline the project and refer the owner to a competitor who specializes in structural stabilization.
C. Provide a provisional GMP with a clearly stated scope limitation and an allowance for additional work once
the structure is stabilized.
D. Submit a low GMP to secure the contract, then submit change orders for all necessary work to make up the
difference.
Answer: C. Provide a provisional GMP with a clearly stated scope limitation and an allowance
for additional work once the structure is stabilized.
2. A restoration company's production manager notices that one of their lead technicians has
been consistently billing for more hours than actually worked on a time-and-materials job. The
owner has an 'at-will' employment policy. What is the MOST appropriate immediate action for
the owner?
A. Terminate the technician immediately to avoid liability for fraudulent billing.
B. Conduct an internal investigation, document findings, and then take appropriate disciplinary action.
C. Report the technician to the local licensing board before confirming the discrepancy.

Answer: B. Conduct an internal investigation, document findings, and then take appropriate
disciplinary action.
3. In a fire-damaged building, the restoration technician is evaluating a segment of wood studs
that were charred. The technician needs to determine the depth of char and the extent of
structural loss to decide between repair and replacement. Which method is the MOST reliable
for this assessment?
A. Using a moisture meter to measure the moisture content of the wood.
B. Tapping the wood with a hammer and listening for a hollow sound.
C. Measuring the char depth with a screwdriver or awl and comparing to the original cross-section.
D. Sending a sample to a laboratory for microscopic analysis.
Answer: C. Measuring the char depth with a screwdriver or awl and comparing to the original
cross-section.
4. A restoration contractor is working on a building that has sustained water damage. During
the drying process, the contractor must decide whether to remove and replace a section of
drywall or dry it in place. Which condition would STRONGLY favor removal and replacement
rather than drying?
A. The drywall is only slightly damp but has been wet for less than 24 hours.
, B. The drywall has visible mold growth on the surface.
C. The drywall is part of a fire-rated assembly that has been compromised.
D. The drywall has a low moisture reading and is drying quickly.
Answer: C. The drywall is part of a fire-rated assembly that has been compromised.
5. A contents restoration technician is assessing a paper document that was water-damaged.
The document is wrinkled and slightly stuck together. What is the FIRST step in the restoration
process to prevent further damage?
A. Freeze the document to halt mold growth and prevent further sticking.
B. Dry the document using high heat to remove moisture quickly.
C. Gently separate the pages while wiping with a damp cloth.
D. Apply a dehumidifier to the room to pull moisture out of the paper.
Answer: A. Freeze the document to halt mold growth and prevent further sticking.
6. During a fire restoration job, a technician is cleaning a delicate antique vase that has soot
and smoke residue. The vase is ornate with gold leaf. Which cleaning technique is LEAST likely
to damage the item?
A. Using a dry chemical sponge to gently wipe the surface.
B. Using a HEPA vacuum with a brush attachment.
C. Using a water-based detergent and soft cloth.
D. Blasting with dry-ice pellets to remove soot.
Answer: B. Using a HEPA vacuum with a brush attachment.
7. A water damage restoration crew is drying a category 3 water loss (sewage) in a residence.
They have removed saturated carpet and pad. What is the MOST critical step to ensure proper
sanitation and prevent health hazards?
A. Treat all affected surfaces with a disinfectant labeled for the specific contaminants.
B. Increase air circulation using high-velocity fans to speed up drying.
C. Apply an antimicrobial agent only to the subfloor.
D. Wet vacuum the subfloor before disposing of the contaminated water.
Answer: A. Treat all affected surfaces with a disinfectant labeled for the specific contaminants.
8. A technician is calculating the drying goals for a water-damaged room. The initial moisture
content of the wood flooring is 12%, and the equilibrium moisture content (EMC) of the room
air at the desired conditions is 7%. What does this information indicate for the drying process?
A. The flooring has a high moisture content and will dry quickly due to the large gradient.
B. The flooring is below the EMC and will absorb moisture from the air.
C. The drying goal should be to bring the flooring to a moisture content of 7%.
D. The room is too humid, and dehumidification must be increased to lower the EMC.
Answer: C. The drying goal should be to bring the flooring to a moisture content of 7%.
9. After a fire, a restorer is evaluating a structural steel beam. The beam is exposed to elevated
temperatures but shows no visible deformation. How should the restorer assess the potential
loss of strength in the steel?
A. Assume that the steel is unaffected because it did not deform.
B. Have a structural engineer evaluate the steel for possible metallurgical changes.
C. Use a heat gun to measure the temperature to determine if it exceeded the critical temperature.
, D. Apply a coat of intumescent paint to restore the original fire rating.
Answer: B. Have a structural engineer evaluate the steel for possible metallurgical changes.
10. A restorer is cleaning a masonry fireplace that was exposed to heavy smoke. The masonry
is porous and has a strong odor. Which method is MOST effective for removing the smoke odor
from the masonry?
A. Wiping the surfaces with a mild detergent and water.
B. Applying an oil-based primer and repainting the fireplace.
C. Using thermal fogging to penetrate the porous surfaces.
D. Sealing the masonry with a clear lacquer.
Answer: C. Using thermal fogging to penetrate the porous surfaces.
11. A mold remediation project involves contaminated drywall in a basement. The restorer
needs to ensure that the mold does not spread to other areas during removal. What is the BEST
containment strategy following IICRC S520 standards?
A. Seal the doorways with plastic sheeting and use negative air pressure.
B. Use a HEPA vacuum on all surfaces after removal.
C. Spray the contaminated area with a disinfectant before removal.
D. Turn off the HVAC system in the basement only.
Answer: A. Seal the doorways with plastic sheeting and use negative air pressure.
12. A technician is performing mold remediation in a crawl space that has a moisture issue.
After removing the moldy materials and cleaning the surfaces, what is the MOST critical
follow-up action to prevent recurrence?
A. Apply an antimicrobial coating to all wood surfaces.
B. Install a new vapor barrier on the ground.
C. Schedule a post-remediation verification test.
D. Identify and correct the source of moisture, such as a plumbing leak or poor drainage.
Answer: D. Identify and correct the source of moisture, such as a plumbing leak or poor
drainage.
13. In a mold remediation project, the restorer is deciding which materials can be cleaned
versus those that must be removed. Which material condition would typically REQUIRE
removal rather than cleaning?
A. Non-porous materials like glass and metal with visible mold growth.
B. Porous materials like carpet and padding that are heavily contaminated with mold.
C. Semi-porous materials like wood that have surface mold.
D. Dense concrete that has mold on the surface.
Answer: B. Porous materials like carpet and padding that are heavily contaminated with mold.
14. A restoration company is bidding on a large commercial water damage project. They must
decide whether to use in-house crews or subcontract part of the work to meet the deadline.
Which consideration is MOST important from a business management perspective?
A. The hourly rate of the subcontractors compared to the in-house crew.
B. The ability to maintain quality control and consistent communication with the owner.
C. The previous relationship with the subcontractor and their availability.
D. The cost of renting additional equipment versus subcontracting labor.
