Governing Law

Civil Engineering Law

The CELE is a two-day objective board exam administered by the PRC Board of Civil Engineering under RA 544. It covers three weighted subjects: Principles of Structural Analysis and Design (~35%), Applied Mathematics/Surveying/Transportation/Construction (~35%), and Hydraulics and Geotechnical Engineering (~30%). Passing requires a weighted general average of at least 70% with no rating below 50% in any subject. Beginning March 2026, PRC reordered the subjects, placing structural analysis and design on Day 1, and that administration recorded 18,370 examinees. The National Structural Code of the Philippines (NSCP) governs structural design.

1Under the CELE syllabus, the Civil Engineer Licensure Examination is administered over two days covering how many major board subjects?
A.Two
B.Three
C.Four
D.Five
Explanation: The CELE covers three major board subjects: Mathematics, Surveying and Transportation Engineering; Hydraulics and Geotechnical Engineering; and Structural Engineering and Construction. They are administered across a two-day examination.
2What is the passing requirement for the PRC Civil Engineer Licensure Examination?
A.A general average of at least 75% with no grade below 60%
B.A weighted general average of at least 70% with no rating below 50% in any subject
C.A simple average of at least 70% in two of the three subjects
D.A scaled score determined by the Board with no fixed percentage
Explanation: PRC requires a weighted general average of at least 70%, with no rating below 50% in any of the three subjects. A candidate who falls below 50% in any subject fails regardless of the overall average.
3Which Republic Act created the Board of Civil Engineering and governs the regulation and licensure of civil engineers in the Philippines?
A.RA 1378
B.RA 544
C.RA 9266
D.RA 8560
Explanation: Republic Act No. 544, the Civil Engineering Law enacted in 1950, regulates the practice of civil engineering and created the Board of Civil Engineering under the PRC.
4A simply supported beam of span L carries a uniformly distributed load w over its entire length. What is the maximum bending moment at midspan?
A.wL²/8
B.wL²/4
C.wL²/2
D.wL²/12
Explanation: For a simply supported beam under a full-span uniform load w, the maximum moment occurs at midspan and equals wL²/8. The end reactions are each wL/2.
5In reinforced concrete design under NSCP 2015 (Ultimate Strength Design), what is the depth of the equivalent rectangular (Whitney) stress block for a singly reinforced rectangular beam?
A.a = A_s f_y / (0.85 f'_c b)
B.a = A_s f_y / (f'_c b)
C.a = 0.85 A_s f_y / (f'_c b)
D.a = A_s f_y / (0.59 f'_c b)
Explanation: Equating the tension force A_s f_y to the compression force 0.85 f'_c b a in the Whitney stress block gives a = A_s f_y / (0.85 f'_c b). The factor 0.85 is the assumed uniform compressive stress over the block.
6In differential leveling, a backsight (BS) of 1.85 m is taken on a benchmark of elevation 100.00 m, and a foresight (FS) of 0.62 m is taken on a turning point. What is the elevation of the turning point?
A.101.23 m
B.98.15 m
C.102.47 m
D.99.38 m
Explanation: Height of instrument = 100.00 + 1.85 = 101.85 m. The turning point elevation = HI − FS = 101.85 − 0.62 = 101.23 m. Adding the BS and subtracting the FS is the rise-and-fall principle of leveling.
7Water flows in a horizontal pipe. According to Bernoulli's energy equation between two points (neglecting head loss), which quantity remains constant along a streamline?
A.The sum of velocity head, pressure head, and elevation head
B.The velocity head alone
C.The product of pressure and velocity
D.The discharge divided by the pressure head
Explanation: Bernoulli's equation states that the total head—the sum of velocity head (V²/2g), pressure head (p/γ), and elevation head (z)—is constant along a streamline for steady, incompressible, frictionless flow.
8A soil sample has a void ratio e = 0.60. What is its porosity n?
A.0.60
B.0.40
C.0.375
D.0.30
Explanation: Porosity relates to void ratio by n = e / (1 + e) = 0.60 / 1.60 = 0.375. Porosity is the ratio of void volume to total volume, while void ratio is void volume to solids volume.
9The PRC adjusted the order of CELE subjects starting which administration, placing Principles of Structural Analysis and Design on the first day?
A.March 2026
B.November 2025
C.August 2026
D.May 2025
Explanation: Beginning with the March 2026 CELE, PRC reordered the subjects so that Principles of Structural Analysis and Design is administered on Day 1, followed by the math/surveying/transportation/construction subject and the hydraulics/geotechnical subject on Day 2.
10A steel rod 2.0 m long with cross-sectional area 200 mm² carries an axial tensile load of 40 kN. Using E = 200 GPa, what is the elongation of the rod?
A.1.0 mm
B.2.0 mm
C.0.5 mm
D.4.0 mm
Explanation: Elongation δ = PL/(AE) = (40000 N)(2000 mm) / (200 mm² × 200000 N/mm²) = 80×10⁶ / 40×10⁶ = 2.0 mm. The axial deformation formula assumes linear-elastic, uniform stress.
