Question 1: A door with small horizontal interlocking metal slats guided in a track that coils around a manual or motor-driven overhead drum at the opening.

Roll-up Door (Correct answer)
Flush Door
Overhead Swing-up Door
Panel Door

Correct answer: Roll-up Door

A roll-up door, also known as a coiling door, is characterized by its construction from small horizontal interlocking metal slats that are guided in tracks. These slats coil around an overhead drum, allowing the door to open vertically and store compactly above the opening. This design is common in garages, commercial buildings, and industrial facilities.

Question 2: Which is not sheet glass?

Picture Glass
Insulating Glass (Correct answer)
Heavy Sheet Glass
Heavy Sheet Glass

Correct answer: Insulating Glass

Sheet glass refers to single, flat panes of glass, such as those used for windows or picture frames. Insulating glass, however, is a multi-pane unit consisting of two or more panes of glass separated by a sealed air or gas space. This construction is designed to enhance thermal insulation, making it fundamentally different from a single sheet of glass.

Question 3: An admixture accelerates concrete setting. For several reasons, adding such a material can speed up early strength development.

Accelerators (Correct answer)
Retarders
Damproofers
Water Reducing Admixtures

Correct answer: Accelerators

Accelerators are chemical admixtures added to concrete to reduce its setting time and promote faster early strength development. They are particularly beneficial in cold weather conditions, allowing concrete to cure more quickly and achieve sufficient strength for subsequent construction activities, thereby speeding up project timelines.

Question 4: Silica-rich rock. Gray, buff, light brown, red.

Marble
Sandstone (Correct answer)
Limestone
Granite

Correct answer: Sandstone

Sandstone is a clastic sedimentary rock predominantly composed of sand-sized mineral particles, primarily quartz, which is rich in silica. Its characteristic range of colors, including gray, buff, light brown, and red, results from various mineral impurities and iron oxides present during its formation, making it a versatile building material.

Question 5: What is a bundle of steel elements like wire, cable, bar, rod, or strand used to prestress concrete?

Tendon (Correct answer)
Prestress Cables
Reinforcement
Tendon Cables

Correct answer: Tendon

In prestressed concrete, a tendon is a high-strength steel element, such as a wire, cable, bar, rod, or strand, that is tensioned to introduce compressive stresses into the concrete. This process, known as prestressing, significantly enhances the concrete's load-bearing capacity and durability by counteracting tensile forces.

Question 6: Excavating or filling earth or other solid materials to prepare for a finishing surface like paving?

Site Preparation
Grading (Correct answer)
Benching
Cut and Fill

Correct answer: Grading

Grading is the process of modifying the land's surface by excavating, filling, and leveling earth or other solid materials to achieve a desired slope or elevation. This essential site preparation step ensures proper drainage, creates a stable foundation for structures, and establishes the correct contours for finishing surfaces like paving or landscaping.

Question 7: A shutter-proof opaque glass used to make a glass door that lets in natural light only.

Bevel Glass
Figured Wired Glass (Correct answer)
Smoked Glass
Etched Glass

Correct answer: Figured Wired Glass

Figured wired glass is a type of safety glass that incorporates a wire mesh embedded within its structure, providing enhanced shatter resistance and fire protection. Its figured (patterned) surface renders it opaque, allowing natural light to transmit through while obscuring direct visibility, making it ideal for doors where privacy and light are both desired.

Question 8: A paint defect caused by application on damp or greasy surfaces, where the film peels off in large pieces.

Peeling (Correct answer)
Bleeding
Cracking
Alligatoring

Correct answer: Peeling

Peeling is a paint defect where the film detaches from the surface in flakes or large pieces. This typically occurs when paint is applied to a poorly prepared surface, such as one that is damp, greasy, or dirty, preventing proper adhesion. The lack of a strong bond between the paint and the substrate causes the film to lift and separate.

Question 9: A "hands of door" with a left hinge and a door leaf that swings left inside the room.

Left Hand (Correct answer)
Right Hand
Left Hand Reverse
Right Hand Reverse

Correct answer: Left Hand

A 'hands of door' refers to the door's swing direction and hinge location when viewed from the exterior or approach side. A 'Left Hand' door has hinges on the left side and swings inward to the left. The description specifies a left hinge and a door leaf that swings left inside the room, which perfectly matches the definition of a Left Hand door.

Question 10: A diagonally cut wood end joint.

Scarf (Correct answer)
Splice
Finger
Lap

Correct answer: Scarf

A scarf joint is a woodworking joint used to connect two pieces of wood end-to-end, typically to create a longer piece. It involves cutting complementary, long, sloping bevels on the ends of both pieces. These angled cuts provide a larger gluing surface area compared to a simple butt joint, resulting in a stronger and more stable connection.

Question 11: A cheap and common masonry finish that sprays dry mortar mix. Spray-applied cement dries rustically. Possible paint coat

Sandblast (Correct answer)
Stucco Finish
Spraytex
Anay Finish

Correct answer: Sandblast

Sandblasting, while primarily a cleaning method, can also be used to create a rustic masonry finish. It involves propelling abrasive material, often sand or a dry mortar mix, at high velocity onto a surface. This process roughens the surface, creating a textured, rustic appearance that can then be left as is or painted.

Question 12: A maintenance-free coating system used to finish and topcoat wood flooring.

Polyurethane Floor Coating (Correct answer)
Epoxy Floor Coating
Polyethylene Floor Coating
Tile Floor Coating

Correct answer: Polyurethane Floor Coating

Polyurethane floor coatings are highly durable, flexible, and resistant to abrasion, chemicals, and moisture, making them ideal for wood flooring. They form a tough, clear finish that protects the wood and requires minimal maintenance once applied. This type of coating is specifically designed to withstand the wear and tear of foot traffic and maintain its appearance over time.

Question 13: A tampicobrush or masonry spoon is used to splatter a thin layer of lean cement grout mixed with flexible base additives on poured concrete walls, beams, and columns to create a "tooth" for excellent plaster adhesion.

Scratch Coat (Correct answer)
Cement Roughing
Concrete Roughing By Chiseling
Splash Coat

Correct answer: Scratch Coat

A scratch coat is the first layer of plaster or stucco applied to a surface, often concrete or masonry. It is intentionally roughened or 'scratched' while still wet using tools like a tampico brush or masonry spoon. This rough texture creates a mechanical 'tooth' or key, providing an excellent bonding surface for subsequent plaster or stucco layers, ensuring strong adhesion.

Question 14: Concrete Hollow Block (CHB) laying slang.

Asintada (Correct answer)
Rebokada
Palitada
Mitsa

Correct answer: Asintada

'Asintada' is a Filipino term commonly used in construction, particularly in masonry work. It refers to the process of laying concrete hollow blocks (CHB) or bricks, ensuring they are properly aligned, leveled, and plumb. This slang term encompasses the entire procedure of setting the blocks in mortar to form a wall.

Question 15: Installing cabinet covers flush with cabinet sidings.

Inset or Interior (Correct answer)
Party Wall or Half Lap
Full Lap or Over Lap
Concealed

Correct answer: Inset or Interior

An 'inset' cabinet door or drawer front is designed to fit precisely within the cabinet frame, flush with the surrounding stiles and rails. This creates a smooth, continuous surface and a clean, traditional aesthetic. The term 'interior' in this context likely refers to the door being contained within the cabinet's perimeter, rather than overlapping it.

Question 16: Decorative concrete flooring and finish<br> This is done by adding dust-on-color pigments to the concrete for a fast color and imprinting a patented pattern and texture while the concrete is plastic to create the look and finish of stone, slate, or brick.

Stucco Floor Finish (Correct answer)
Concrete Block Cushion
Impressio-crete
Textfloor-crete

Correct answer: Stucco Floor Finish

The description details a process of creating decorative concrete flooring by adding color pigments and imprinting patterns into wet concrete to mimic natural materials like stone or brick. While 'stucco' is traditionally a wall finish, in some specialized or regional contexts, a 'stucco floor finish' might refer to a decorative concrete treatment that achieves a similar textured and aesthetic effect on floors. This method transforms plain concrete into an attractive, patterned surface.
