Formwork & Shoring Technician Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of formwork in concrete construction?
• To reinforce concrete
• To shape and support fresh concrete until it attains sufficient

strength

• To provide decorative finish
• To reduce concrete curing time

Rationale: Formwork is used to mold and support fresh concrete until

it can support its own weight.

• Which type of formwork is most suitable for high-rise structures?
• Timber formwork
• Steel formwork 1 / 4

• Plywood formwork
• Plastic formwork

Rationale: Steel formwork is strong, durable, and reusable, making it

ideal for repetitive high-rise construction.

• What is the minimum concrete cover required over reinforcement in a

slab exposed to weather?

• 10 mm
• 15 mm
• 25 mm
• 40 mm

Rationale: Adequate concrete cover protects steel reinforcement

from corrosion and fire.

• Which property of formwork material is most critical for heavy-load

structures?

• Color
• Flexibility
• Strength
• Weight

Rationale: Strength is critical to safely support fresh concrete loads

without failure.

5. When shoring, the vertical members must be:

• Plumb and properly braced
• Tilted slightly for drainage 2 / 4

• Spaced randomly
• Unbraced for flexibility

Rationale: Vertical members must be plumb and braced to safely

transfer loads to the foundation.

• What is the main advantage of modular formwork?
• Single-use only
• High labor requirements
• Faster assembly and reuse
• Heavy and difficult to move

Rationale: Modular formwork allows rapid assembly and

disassembly and can be reused multiple times.

• What should be done before removing formwork from a concrete

slab?

• Remove immediately after pouring
• Wait 24 hours regardless of conditions
• Ensure concrete has attained sufficient strength
• Pour more concrete to reinforce

Rationale: Removing formwork too early may cause structural

damage or collapse.

• Which type of shoring is temporary and removed after concrete

hardens?

• Permanent shoring
• Falsework 3 / 4

• Scaffolding
• Cantilever formwork

Rationale: Falsework is temporary support for concrete structures

until self-supporting.

• In formwork design, the lateral pressure of fresh concrete is

influenced most by:

• Temperature
• Rate of concrete placement
• Color of concrete
• Type of curing

Rationale: Faster placement increases lateral pressure on formwork

and may cause failure.

• Which formwork component transmits the load from slabs to

supports?

• Tie rods
• Beams and joists
• Ply sheets
• Nails

Rationale: Beams and joists carry loads from the slab to the shoring

posts.

• What is the purpose of form ties?
• Reduce curing time
• Support scaffolding
