Sample Model Questions & Step-by-Step Solutions

Practice representative questions modeled after actual council examination standards.

Sample Question 1

For a highway designed for 80 km/h with a coefficient of lateral friction f = 0.15, what is the design superelevation for a circular curve with radius R = 250 m (ignoring friction for full superelevation)?

A.e = 0.07

B.e = 0.10

C.e = 0.20

D.e = 0.05

Correct Answer: e = 0.07

Explanation: Per standard highway design codes (IRC/NRS), design superelevation for 75% speed (V_design) is calculated as e = V² / (225 * R) = (80)² / (225 * 250) = 6400 / 56250 = 0.113. However, maximum permissible superelevation in plain terrain is capped at 7% (0.07).

Sample Question 2

According to Terzaghi's bearing capacity formula, what is the value of the shape factor sc for an isolated square footing?

A.1.0

B.1.2

C.1.3

D.0.8

Correct Answer: 1.3

Explanation: Terzaghi's ultimate bearing capacity for a square footing modifies cohesion by a shape factor of 1.3: q_ult = 1.3 * c * Nc + q * Nq + 0.4 * gamma * B * Ngamma.

Sample Question 3

In a rapid sand filter, which mechanism is primarily responsible for clearing clogged sand beds during backwashing?

A.Surface skimming

B.Upward flow of treated water with compressed air agitation

C.Chemical oxidation with chlorine gas

D.Downward gravitational suction

Correct Answer: Upward flow of treated water with compressed air agitation

Explanation: Rapid sand filters are cleaned by reversing the flow: clean water is forced upward through the gravel and sand beds while compressed air agitates the sand particles to dislodge trapped floc and suspended impurities.

Sample Question 4

Under the Public Procurement Act of Nepal, what is the validity period of a bid security from the deadline of bid submission?

A.Minimum 30 days beyond bid validity

B.Exactly 15 days

C.Minimum 60 days beyond bid validity

D.90 days total regardless of bid period

Correct Answer: Minimum 30 days beyond bid validity

Explanation: Under the Public Procurement Act 2063 of Nepal, bid security must remain valid for at least 30 days beyond the original bid validity period stipulated in the bidding document.

Frequently Asked Questions (Civil Engineering)

How should civil engineers prepare for the 2-mark questions in the NEC exam?

Focus on standard civil calculations: sight distance (SSD/OSD), superelevation, critical depth in open channels, Mohr-Coulomb shear parameters, bending stress equations, and float calculations in CPM network charts.

Does the NEC Civil Engineering exam follow IS codes or Nepal National Building Codes (NBC)?

Both NBC and Indian Standard (IS) codes are relevant. Most RCC and structural questions reference standard limit state design principles identical across IS 456:2000 and NBC 105:2020.

Is there negative marking in the Civil Engineering licensure exam?

No, there is currently no negative marking for incorrect answers. Candidates are advised to answer all 80 questions within the 120-minute examination duration.
