TESDA Carpentry NC II (Construction Sector, Civil Works) is the Philippines national competency for carpenters. Assessment is competency-based with written, oral, and practical components. Core units cover stake-out, formworks, framing, sheathing, and door/window installation per the 29 Oct 2018 Training Regulations.

1According to the TESDA Carpentry NC II Training Regulations, what is the first core competency unit a carpenter must demonstrate?
A.Prepare and stake-out building lines
B.Install stair components
C.Perform basic masonry works
D.Install built-in cabinets
Explanation: The Carpentry NC II core competencies begin with CON712317 Prepare/Stake-out building lines, followed by formwork fabrication, installation, stripping, framing, sheathing, and door/window work. Stair components and cabinets belong to Carpentry NC III.
2A carpenter needs to verify that a building corner is square before staking footings. Which method is most appropriate?
A.Measure the diagonals of the layout rectangle; equal diagonals indicate a square corner layout
B.Measure only one side length and assume the opposite side is equal
C.Use a spirit level on each batter board stake
D.Sight along one string line and estimate the 90-degree angle by eye
Explanation: Comparing diagonal measurements of a rectangular layout is a standard field method to confirm 90-degree corners. If both diagonals are equal, opposite sides are parallel and corners are square. A 3-4-5 triangle check on one corner is also used, but diagonal equality verifies the entire rectangle.
3What is the primary purpose of batter boards used during building stake-out?
A.To hold string lines at a fixed elevation and offset from the excavation so layout can be transferred accurately
B.To support concrete formwork during the pour
C.To brace wall studs during framing
D.To serve as permanent boundary markers after construction
Explanation: Batter boards are horizontal boards on stakes placed beyond the building corners. They hold string lines at reference heights and offsets, allowing workers to locate footing corners and building lines even after excavation removes corner stakes.
4When staking out a rectangular footing, the carpenter sets offset lines 1 meter outside the building lines. Why are offset lines used?
A.To preserve layout references after excavation removes corner stakes and to keep string lines clear of digging
B.To reduce the total length of string line required on site
C.To mark the finished floor elevation only
D.To indicate the roof ridge line location
Explanation: Offset lines are established parallel to building lines at a set distance outside the excavation. They remain undisturbed when corners are dug out, so the building footprint can still be transferred accurately to the bottom of the footing.
5Which personal protective equipment is required when staking out a building on an active construction site per OSH standards referenced in Carpentry NC II?
A.Hard hat, safety shoes, and other PPE appropriate to site hazards such as eye protection when hammering stakes
B.Welding helmet and leather apron
C.Full chemical suit and respirator
D.Hearing protection only, with no head protection
Explanation: TESDA Carpentry NC II units require appropriate PPE per OSHC specifications and Rule 1080 of the Occupational Safety and Health Standards. On construction sites this typically includes a hard hat, safety footwear, and task-appropriate protection such as safety glasses when driving stakes.
6A plan shows a dimension of 4500 mm from the property line to the building face. During stake-out, this dimension represents:
A.The distance to be measured and marked on the ground from the established reference point to the building line
B.The height of the batter board above ground
C.The thickness of the concrete footing only
D.The spacing between wall studs
Explanation: Plan dimensions during stake-out are transferred to the ground using measuring tapes, plumb bobs, and string lines from established reference points such as property boundaries or survey benchmarks.
7What tool is commonly used to transfer a point on a string line vertically to the ground or footing bottom?
A.Plumb bob
B.Chalk line
C.Framing square only
D.Wood chisel
Explanation: A plumb bob hangs a weighted line vertically from a point on a string line or batter board, allowing accurate transfer of horizontal layout positions to the ground or excavation bottom.
8When interpreting construction plans for stake-out, a dashed line on a foundation plan most commonly indicates:
A.A hidden or below-grade element such as a footing below the slab
B.A property boundary fence
C.A decorative ceiling feature
D.A roof overhang edge
Explanation: Standard architectural drawing conventions use dashed lines for elements that are hidden, below grade, or above the cut plane. On foundation plans, dashed lines often show footings beneath the slab.
9The 3-4-5 method is used during stake-out to:
A.Establish a 90-degree angle at a corner using a triangle with sides in a 3:4:5 ratio
B.Calculate board feet of lumber needed for formwork
C.Determine concrete mix proportions
D.Set the slope of a stair stringer
Explanation: The 3-4-5 method applies the Pythagorean theorem: a triangle with sides 3, 4, and 5 units has a right angle opposite the 5-unit side. Carpenters measure 3 m and 4 m from a corner along perpendicular lines; if the diagonal equals 5 m, the corner is square.
10After marking building corners on the ground, the carpenter finds one diagonal is 50 mm longer than the other. What does this indicate?
A.The layout is not square and corners must be adjusted before proceeding
B.The footing concrete will be too weak
C.The string line tension is too high only, with no effect on squareness
D.The building will automatically self-correct during framing
Explanation: Unequal diagonals in a rectangular layout mean the corners are not 90 degrees or opposite sides are not equal. The layout must be corrected before excavation or formwork because errors compound in later construction stages.
