BE Civil Engineering (IOE, TU) Engineering Professional Practice (IOE, CE 753) Question Paper 2080 Nepal

a) Professional ethics vs. personal morality (3 marks)

Professional ethics is the system of moral principles, rules of conduct and obligations that governs the behaviour of members of a profession in the exercise of their professional duties. For engineers it is codified (e.g. by the Nepal Engineering Council) and is binding on registered members.

Distinction: Personal morality is the individual's private set of right/wrong beliefs shaped by upbringing, religion and culture, and varies from person to person. Professional ethics is a shared, externally enforced standard tied to a professional role; breach can lead to disciplinary action (suspension/cancellation of registration), whereas breach of personal morality carries no such institutional sanction.

Example: An engineer may personally have no objection to working long unpaid hours, but professional ethics still requires that they never certify substandard work as safe even if their personal loyalty to a friend-contractor would incline them to do so. The public-safety obligation overrides personal preference.

b) Four fundamental canons, ranked by priority (4 marks)

1. Hold paramount the safety, health and welfare of the public — the highest canon; whenever any other duty conflicts with public safety, public safety prevails. (e.g. refuse to sign off on an unsafe structure)
2. Perform services only in areas of competence — engineers must undertake only assignments for which they are qualified by training and experience, and seek expert help otherwise.
3. Act as faithful agents/trustees for each employer or client and avoid conflicts of interest — disclose any interest that could bias judgement; maintain confidentiality.
4. Conduct themselves honourably, responsibly and lawfully — issue truthful, objective statements, give proper credit, avoid deceptive acts and uphold the dignity of the profession.

The ranking matters because canon 1 is non-negotiable: it is the tie-breaker when duties to client, employer or self conflict.

c) Ethical response using a decision framework (3 marks)

Apply a structured framework (recognise → gather facts → identify stakeholders & duties → evaluate options → act → reflect):

1. Recognise the issue: acceptance of below-grade concrete in a critical bridge pier is a public-safety and honesty problem, not a mere scheduling matter.
2. Gather facts: confirm the deficiency objectively — re-test cube/cylinder samples and verify slump results against the specification; document everything in writing.
3. Identify duties & the conflict: duty to public safety + faithful agent of the client/owner vs. personal/family loyalty (a clear conflict of interest that must be disclosed).
4. Evaluate options: (i) accept under pressure — violates the paramount safety canon and is unacceptable; (ii) quietly substitute later — dishonest; (iii) reject the non-conforming material, formally document, disclose the relationship, and escalate to the consultant/owner — the only ethically defensible path.
5. Act: reject the load, issue a non-conformance report, declare the family relationship and request reassignment of any approval authority over that contractor, and require compliant replacement concrete with fresh testing.
6. Reflect/justify: the choice is defensible because it places public safety paramount and resolves the conflict of interest transparently.

Conclusion (bold): The engineer must refuse the substandard concrete, document and disclose the conflict, and escalate — personal loyalty can never override the paramount duty to public safety.

a) Essential elements of a valid contract (3 marks)

1. Offer and acceptance — a clear bid (offer) and an unconditional acceptance (letter of acceptance/award).
2. Lawful consideration — exchange of value (work for payment) that is legal.
3. Capacity of parties — parties must be competent (legal entities, of sound mind, not disqualified/blacklisted).
4. Free consent — agreement free of coercion, undue influence, fraud, misrepresentation.
5. Lawful object — the purpose must not be illegal or against public policy.
6. Certainty & possibility of performance — terms (scope, price, time) must be definite and capable of being performed.

b) Methods of procurement / tendering (3 marks)

Open bidding maximises value-for-money and competition; limited bidding trades some competition for suitability/speed; direct procurement sacrifices competition and is used only for justified exceptions with proper records.

c) Lowest bid, abnormally low bid, and variance (4 marks)

Definition: An abnormally low bid is one that appears so low relative to the engineer's estimate (and the spread of other bids) that it raises a reasonable concern the bidder cannot perform the contract at that price for the required quality and time.

Variance from the engineer's estimate (E = NPR 100,000,000):

Lowest bid, B₁ = 78,000,000:

$$\text{Variance}=\frac{78{,}000{,}000-100{,}000{,}000}{100{,}000{,}000}\times100\% = -22\%$$

so B₁ is 22% below the estimate.

Next bid, B₂ = 95,000,000:

$$\text{Variance}=\frac{95{,}000{,}000-100{,}000{,}000}{100{,}000{,}000}\times100\% = -5\%$$

so B₂ is 5% below the estimate.

Discussion: The principle is lowest substantially responsive bid wins, but B₁ at 22% below estimate (and ~18% below the next bid: $(78-95)/95 = -17.9\%$) is a strong indicator of an abnormally low bid. The committee should NOT mechanically award; it must:

1. Confirm the bid is substantially responsive (meets technical/qualification criteria, valid bid security).
2. Seek a written clarification/justification of the rates and methodology from the bidder (price breakdown, source of materials, productivity assumptions).
3. Verify the bidder's financial and technical capacity to deliver at that price without compromising quality/time.
4. If the justification is satisfactory, require additional performance security (an increased performance bond) before award; if unsatisfactory, reject the bid and consider the next responsive bidder.

Conclusion (bold): B₁ is 22% below and B₂ is 5% below the estimate; the 22%-low bid must be treated as potentially abnormally low and verified (clarification + capacity check + enhanced performance security) before it can be awarded — it cannot be rejected solely for being low, nor awarded without scrutiny.

a) FIDIC and its principal books (3 marks)

FIDIC = Fédération Internationale des Ingénieurs-Conseils (International Federation of Consulting Engineers), which publishes standard international conditions of contract.

b) Role and duties of the Engineer (Red Book) (3 marks)

The Engineer is appointed by the Employer to administer the contract but must act professionally. Key duties:

• Contract administration: issue drawings/instructions, review the contractor's documents, supervise and monitor progress.
• Certification: measure work, certify interim and final payments, issue Taking-Over and Performance Certificates.
• Determinations: decide on claims, variations, EoT and additional cost.
• Fair determination: when the contract requires the Engineer to agree or determine a matter, the Engineer must consult both parties to reach agreement, and failing agreement make a fair determination in accordance with the contract, taking due regard of all relevant circumstances — acting neutrally and professionally, not merely as the Employer's agent. (In modern editions a Dispute Avoidance/Adjudication Board reviews disputes.)

c) EoT and liquidated damages (4 marks)

(i) Notice/claim procedure: The contractor must give notice of the claim as soon as practicable (and within the contractual time bar — 28 days of becoming aware of the event in the 1999 Red Book); keep contemporary records; submit a fully detailed claim within the prescribed period (42 days) with supporting particulars and the EoT/cost claimed; the Engineer then responds and makes a fair determination. Missing the time bar can forfeit the claim.

(ii) LD when 45 days EoT is granted: If the full 45-day delay is justified and granted as EoT, the Time for Completion is extended by 45 days, so the contractor is not late.

$$\text{LD} = \textbf{NPR } 0$$

(iii) Only 30 days granted, project 15 days beyond extended time: Granted EoT = 30 days, so the contractor is responsible for the 15 days of overrun.

$$\text{LD} = 15 \text{ days} \times \text{NPR } 60{,}000/\text{day} = \textbf{NPR } 900{,}000$$

Check against the cap:

$$\text{Cap} = 10\% \times \text{NPR } 200{,}000{,}000 = \text{NPR } 20{,}000{,}000$$

Since NPR 900,000 < NPR 20,000,000, the cap is not exceeded.

Conclusion (bold): With full 45-day EoT, LD = NPR 0; with 30-day EoT and a 15-day overrun, LD = NPR 900,000, well below the NPR 20,000,000 cap.

a) Arbitration: definition, advantages and disadvantages (4 marks)

Arbitration is a private, consensual method of dispute resolution in which the parties refer their dispute to one or more neutral arbitrators whose decision (the award) is binding and enforceable, instead of going to court.

Advantages (vs. litigation):

1. Speed — generally faster than crowded courts.
2. Expertise — arbitrators with technical/engineering knowledge can be chosen.
3. Confidentiality / privacy — proceedings are not public.
4. Flexibility & party autonomy — parties choose procedure, venue, language; finality (limited appeal).

Disadvantages:

1. Cost — arbitrator fees + venue can make it expensive.
2. Limited appeal/review — errors are hard to correct; very narrow grounds to challenge.
3. No binding precedent / inconsistency — awards do not create case law.
4. Limited powers over third parties — cannot easily join non-signatories or compel outsiders.

b) Dispute-resolution ladder (3 marks)

A typical escalating ladder:

1. Engineer's / employer's determination — the contract administrator decides the matter (fair determination).
2. Amicable negotiation between the parties — direct settlement talks.
3. Mediation / conciliation — a neutral facilitates a voluntary settlement (non-binding).
4. Dispute Adjudication / Avoidance Board (DAB/DAAB) — a standing or ad-hoc board gives a prompt binding-unless-revised decision.
5. Arbitration — if the DAB decision is rejected by notice of dissatisfaction and amicable settlement fails, the dispute goes to binding arbitration.
6. Litigation/courts — only for enforcement or setting aside the award, not a re-hearing.

The ladder is designed to resolve disputes at the lowest, cheapest, fastest rung possible and reserve arbitration/courts as a last resort.

c) Salient features of the Arbitration Act, 2055 (1999) of Nepal (3 marks)

• Scope/agreement: applies where parties have a written arbitration agreement/clause; disputes are referred to arbitration accordingly.
• Appointment of arbitrators: parties appoint arbitrator(s) as agreed; commonly an odd number (e.g. one or three). Failing agreement, the appointing authority/court appoints. Arbitrators must be impartial and independent and can be challenged for justifiable doubts as to neutrality.
• Award & time frame: the tribunal must render a reasoned, written and signed award; the Act prescribes a statutory time limit (e.g. award within 120 days of receiving the documents, extendable) for completing proceedings. The award is binding and enforceable like a court decree.
• Setting aside (court's limited role): a party may apply to the High Court to set aside an award on narrow grounds, such as: the party was not given proper notice / opportunity to be heard, the dispute fell outside the arbitration agreement, the tribunal/composition or procedure was not in accordance with the agreement/law, the award is against public policy/Nepal law, or it was induced by fraud/corruption.

Conclusion (bold): Arbitration offers speedy, expert, private and binding resolution but at the cost of expense and very limited appeal; under Nepal's Arbitration Act 2055, awards are binding within statutory time limits and courts intervene only on narrow setting-aside grounds.

a) PPP and modalities (4 marks)

Public-Private Partnership (PPP) is a long-term contractual arrangement between a public authority and a private party in which the private party finances, builds and/or operates public infrastructure and bears significant risk in return for revenue (tolls/availability payments), with assets ultimately serving public purposes.

Risk migrates progressively to the private sector from DBFO (often availability-based) to BOOT (ownership + market risk).

b) Advantages and risks of PPP for the public sector (2 marks)

Advantages: (i) mobilises private capital without immediate public borrowing; (ii) transfers construction/operation risk and brings private-sector efficiency, innovation and lifecycle management.

Risks: (i) higher total financing cost and complex, costly contracts; (ii) long-term fiscal/contingent liabilities and the risk of renegotiation or demand shortfall falling back on the public.

c) BOT financial analysis (4 marks)

Given: Investment $I = 4{,}000$ million; annual net cash flow $A = 700$ million/yr; discount rate $i = 10\% = 0.10$.

(i) Simple (undiscounted) payback period:

$$\text{Payback}=\frac{I}{A}=\frac{4{,}000}{700}=5.714\ \text{years}\approx \textbf{5.71 years (about 5 years 9 months)}.$$

(ii) Minimum concession period using present value: We need the present value of an $n$-year annuity to recover $I$:

$$PV = A\times\frac{1-(1+i)^{-n}}{i}\ \ge\ I$$ $$700\times\frac{1-(1.10)^{-n}}{0.10}\ \ge\ 4{,}000$$ $$\frac{1-(1.10)^{-n}}{0.10}\ \ge\ \frac{4{,}000}{700}=5.714$$ $$1-(1.10)^{-n}\ \ge\ 0.5714 \;\Rightarrow\; (1.10)^{-n}\ \le\ 0.4286$$ $$-n\ln(1.10)\le\ln(0.4286)\;\Rightarrow\; n\ \ge\ \frac{-\ln(0.4286)}{\ln(1.10)}=\frac{0.8473}{0.09531}=8.89\ \text{years}.$$

Check whole years:

• $n=8$: factor $=\dfrac{1-1.10^{-8}}{0.10}=\dfrac{1-0.46651}{0.10}=5.335$; $PV=700\times5.335=3{,}734$ M $<4{,}000$ M (not recovered).
• $n=9$: factor $=\dfrac{1-1.10^{-9}}{0.10}=\dfrac{1-0.42410}{0.10}=5.759$; $PV=700\times5.759=4{,}031$ M $>4{,}000$ M (recovered).

Conclusion (bold): Simple payback ≈ 5.71 years; on a discounted (10%) basis the investment is recovered only in year 9, so the minimum concession period required is 9 years.

Nepal Engineering Council (NEC) (5 marks)

The Nepal Engineering Council is the statutory body established under the Nepal Engineering Council Act, 2055 BS to regulate the engineering profession in Nepal.

Objectives: to make the engineering profession systematic, competent and accountable, to protect the public interest, and to maintain professional standards and dignity.

Main functions:

1. Registration of qualified engineers and maintaining the register of engineers.
2. Recognition / accreditation of engineering academic qualifications and institutions for the purpose of registration.
3. Setting and enforcing standards of professional conduct (code of ethics).
4. Conducting/regulating registration examinations and prescribing eligibility criteria.
5. Taking disciplinary action against misconduct.
6. Advising the government on engineering-education and professional-practice matters.

Why registration is mandatory: A person must be registered with the NEC to legally practise as an engineer / use the title and sign-off on engineering work in Nepal. Registration certifies that the engineer holds a recognised qualification and is competent and accountable, which protects the public from unqualified practitioners and gives the Council jurisdiction to enforce ethics.

Disciplinary powers: On proven professional misconduct, negligence, fraud, or breach of the code of ethics, the Council may warn/reprimand, suspend registration for a period, or cancel (strike off) the engineer's registration, thereby barring them from practice. The engineer is given a chance to be heard, with provision to appeal.

Key point (bold): NEC registration is the legal license to practise engineering in Nepal; it ensures competence and accountability, and the Council can suspend or cancel registration for professional misconduct.

Intellectual Property (5 marks)

Intellectual property (IP) refers to creations of the human mind — inventions, literary and artistic works, designs, symbols, names — over which the law grants the creator exclusive rights for a limited period.

Key distinctions: A patent protects a functional invention (how it works) and requires registration after examination; copyright protects the expression of an idea and arises automatically on creation; a trademark protects brand identity and can last indefinitely with renewal.

Purpose of IP protection: to reward and incentivise innovation and creativity by granting exclusive commercial rights, to enable fair recovery of R&D investment, to encourage disclosure of knowledge (patents are published), and to protect against unfair copying/passing-off.

Key point (bold): Patents protect inventions, copyrights protect original expression, and trademarks protect brand identity — collectively IP rewards innovation and prevents unauthorised exploitation.

Bid security vs. performance security (5 marks)

Computations (contract value $C =$ NPR 150,000,000):

Bid security at 2.5%:

$$0.025\times150{,}000{,}000=\textbf{NPR }3{,}750{,}000$$

Performance security at 5%:

$$0.05\times150{,}000{,}000=\textbf{NPR }7{,}500{,}000$$

When returned:

• Bid security is returned to unsuccessful bidders soon after award/contract signing, and to the successful bidder once the performance security is furnished and the contract is signed.
• Performance security is released after successful completion of the work and expiry of the defects-liability/maintenance period (when obligations, including making good defects, are fully discharged), often replaced by retention/retention-money arrangements during the warranty period.

Key point (bold): Bid security (NPR 3,750,000 at 2.5%) safeguards the tender stage; performance security (NPR 7,500,000 at 5%) safeguards execution and is released only after the defects-liability period.

Engineer's social responsibility & sustainability (5 marks)

Social responsibility means that engineers are accountable not only to their client/employer but to society and the environment. Because engineering works (dams, roads, buildings, water systems) directly affect public safety, livelihoods and ecosystems, the engineer's first duty is to hold paramount the safety, health and welfare of the public and to minimise harm to the environment and future generations.

Key responsibilities:

• Ensure public safety and structural reliability.
• Avoid/minimise environmental damage (pollution, deforestation, disruption of rivers/habitats).
• Promote equitable benefit and consider affected communities (consultation, fair resettlement).
• Use resources efficiently and avoid waste and corruption.
• Practise honesty and transparency in public projects.

Sustainable development — meeting present needs without compromising the ability of future generations to meet theirs — reshapes practice across three pillars: economic, social and environmental. It pushes engineers to consider whole-life cost, resource efficiency, resilience to climate/seismic hazards, and environmental & social impact assessment (EIA/IEE) before construction.

Two concrete examples:

1. Green/seismic-resilient buildings: designing energy-efficient, earthquake-resistant structures using local, low-carbon materials and rainwater harvesting — reducing lifecycle energy use and disaster risk.
2. Sustainable road / hydropower projects: incorporating proper bioengineering for slope stability, sediment and fisheries management, environmental flow releases, and community benefit-sharing to balance development with ecology.

Key point (bold): Engineers must serve society and the environment, not just clients; sustainable-development principles make whole-life, low-impact, resilient and inclusive design a professional obligation.

Variation order and valuation (5 marks)

Variation order (VO): a written instruction by the Engineer/Employer to change the works — altering the quantity, quality, character, scope, sequence or design from what the original contract specified — issued within the powers granted by the contract.

Two reasons variations arise:

1. Design changes / client requirements — modifications by the owner, design errors/omissions, or improved specifications.
2. Unforeseen site conditions — differing ground/geotechnical conditions, additional/reduced quantities discovered on remeasurement, statutory changes.

Valuation (remeasured item): Given: BOQ quantity $Q_0 = 2{,}000\ \text{m}^3$, rate $r = \text{NPR }450/\text{m}^3$, executed quantity $Q = 2{,}600\ \text{m}^3$.

Extra quantity:

$$\Delta Q = 2{,}600-2{,}000 = 600\ \text{m}^3$$

Value of the varied (extra) work (at the same contract rate):

$$\Delta V = 600\ \text{m}^3 \times \text{NPR }450/\text{m}^3 = \textbf{NPR }270{,}000$$

Revised total item value:

$$V = 2{,}600\ \text{m}^3 \times \text{NPR }450/\text{m}^3 = \textbf{NPR }1{,}170{,}000$$

(Check: original item value $=2{,}000\times450=\text{NPR }900{,}000$; $900{,}000+270{,}000=1{,}170{,}000$. ✓)

Rule normally applied: For a remeasured (admeasurement) contract, the actual measured quantity is paid at the applicable BOQ/contract rate. The extra 600 m³ is +30% of the BOQ quantity ($600/2000$); if the variation in quantity is within the limit stated in the contract, the same contract rate applies, but if it exceeds the threshold (commonly ~15–25%) or materially changes the nature/cost of the work, a new/adjusted rate may be agreed or fairly determined by the Engineer.

Key point (bold): Extra work value = NPR 270,000; revised item value = NPR 1,170,000; paid at the BOQ rate under remeasurement, subject to rate review if the quantity variation exceeds the contract threshold.

Conflict of interest and whistleblowing (5 marks)

Conflict of interest (COI): a situation in which an engineer's personal, financial or family interest could improperly influence — or appear to influence — their professional judgement or duty to a client, employer or the public. The harm is to the objectivity and trust expected of the engineer.

Example: An engineer who evaluates tenders also secretly owns shares in (or is related to the owner of) one of the bidding contractors, or recommends purchasing materials from a company owned by a relative.

Ethical handling of COI:

1. Disclose the interest fully and promptly to the employer/client.
2. Recuse / withdraw from the decision or evaluation affected.
3. Avoid accepting gifts/favours that create obligation.
4. Put the public interest and faithful-agent duty first; transparency is the cure.

Whistleblowing: the act of an engineer reporting serious wrongdoing — such as a danger to public safety, fraud, corruption, or violation of law/regulations — that an employer or colleague is committing or concealing, often by raising it beyond immediate management (to authorities/regulator) when internal channels fail.

Example: An engineer discovers the employer is using substandard reinforcement bars in a public bridge and, after internal reporting is ignored, reports it to the regulatory authority/NEC to protect the public.

Ethical handling of whistleblowing:

1. First raise the concern internally through proper channels and document it.
2. Verify facts and rely on credible evidence, acting in good faith (not for revenge).
3. If the danger to public safety persists and is ignored, escalate to the appropriate external authority — because the paramount duty to public safety overrides loyalty to the employer.
4. Maintain confidentiality of unrelated information and follow legal protections for whistleblowers.

Key point (bold): Conflicts of interest are managed by disclosure and recusal; whistleblowing — escalating genuine public-safety dangers — is justified when the paramount duty to public safety outweighs employer loyalty.
