BE Civil Engineering (IOE, TU) Engineering Professional Practice (IOE, CE 753) Question Paper 2076 Nepal

Engineering Ethics

Engineering ethics is the field of applied ethics that examines the moral principles, standards of conduct, and professional obligations governing the practice of engineering. It guides engineers in making decisions that are honest, fair, competent, and responsible toward clients, employers, colleagues, society, and the environment.

Why ethical conduct is fundamental

1. Public trust – Civil engineers design structures (bridges, dams, buildings) on which life depends. Society grants engineers professional autonomy in exchange for a guarantee of responsible behaviour.
2. Asymmetry of knowledge – The public cannot independently verify the technical adequacy of a design; they must trust the engineer's integrity and competence.
3. Irreversibility of failure – Structural failures cause loss of life, injury and large economic loss that cannot be undone.
4. Legal and contractual accountability – Engineers carry statutory liability (Nepal Engineering Council Act) and contractual liability.

Paramountcy of public safety, health and welfare

Virtually every professional code (NEC Code of Ethics, ASCE, FIDIC) places "hold paramount the safety, health and welfare of the public" as the first canon. This means that when a conflict arises between the engineer's duty to the client/employer and the duty to the public, public welfare always prevails.

Real failure scenario (illustrative): Consider a multi-storey building where the owner pressures the engineer to reduce the reinforcement and column sizes to cut cost, knowing the site lies in a high seismic zone. If the engineer yields, the building may collapse during an earthquake (as widely observed in poorly-detailed buildings during the 2015 Gorkha earthquake). The paramountcy principle requires the engineer to:

• Refuse to certify an unsafe design,
• Document the objection in writing,
• Report to the relevant authority/NEC if the unsafe work proceeds.

Conflict of Interest (COI)

A conflict of interest exists when an engineer's personal, financial, or other interest could improperly influence (or appear to influence) professional judgement.

Examples: approving a contractor in which the engineer holds shares; accepting gifts from a supplier whose materials the engineer specifies; designing and also independently "checking" the same work.

Management strategies:

Conclusion: Ethical practice protects the public, sustains professional credibility, and shields the engineer from legal liability. Holding public welfare paramount and managing conflicts of interest transparently are the cornerstones of responsible civil engineering.

Essential elements of a valid contract

1. Offer and acceptance – A definite proposal accepted unconditionally.
2. Lawful consideration – Something of value exchanged between parties.
3. Capacity of parties – Parties must be competent (of age, sound mind, not disqualified by law).
4. Free consent – Consent not obtained by coercion, undue influence, fraud, misrepresentation or mistake.
5. Lawful object – The purpose must not be illegal, immoral or against public policy.
6. Certainty and possibility of performance – Terms must be clear and capable of being performed.
7. Intention to create legal relations and not expressly declared void.

Tendering process for public construction work (Nepal)

Governed by the Public Procurement Act 2063 and Regulations 2064.

1. Need identification & cost estimate – Prepare detailed estimate, drawings, specifications.
2. Procurement planning & budget – Confirm funds and method.
3. Invitation for Bids (IFB) – Publish notice (national/international) in newspaper and PPMO e-GP portal.
4. Issue of bid documents – Contractors purchase/download documents.
5. Pre-bid meeting – Clarify queries; issue addenda if needed.
6. Submission & receipt of bids – Bids with bid security submitted by deadline.
7. Bid opening – Opened publicly in presence of bidders.
8. Evaluation – Preliminary (responsiveness), technical, and financial evaluation; determine lowest substantially responsive bid.
9. Award & Letter of Acceptance (LoA) – Notify successful bidder.
10. Performance security & contract signing – Bidder furnishes performance security; agreement executed.

Open competitive bidding vs sealed quotation

Numerical computation

Given: Estimated cost $E = \text{NRs } 25{,}000{,}000$; bid security $= 2.5\%$ of $E$; performance security $= 5\%$ of contract amount; contract (award) amount $C = \text{NRs } 23{,}800{,}000$.

Bid security:

$$\text{BS} = 0.025 \times 25{,}000{,}000 = \text{NRs } 625{,}000$$

Performance security:

$$\text{PS} = 0.05 \times 23{,}800{,}000 = \text{NRs } 1{,}190{,}000$$

Final answers: Bid security = NRs 625,000 and Performance security = NRs 1,190,000.

The FIDIC suite of contracts

FIDIC (Fédération Internationale des Ingénieurs-Conseils — International Federation of Consulting Engineers) publishes internationally-used standard conditions of contract that allocate risk between Employer and Contractor.

Colour coding of principal books

Role and duties of the Engineer (FIDIC Red Book)

The Engineer is appointed by the Employer but must act fairly and professionally. Duties include:

• Administering the contract on behalf of the Employer.
• Issuing drawings, instructions, and variations.
• Reviewing and certifying interim and final payments.
• Determining claims and disputes fairly (making a fair determination after consulting both parties).
• Granting extensions of time (EOT).
• Inspecting, testing and approving works; issuing the Taking-Over and Defects certificates.

Under the contract the Engineer must act impartially when making determinations even though paid by the Employer.

Numerical: prolongation cost claim

Given: Delay $= 18$ days (employer-risk, unforeseen ground conditions); time-related cost $= \text{NRs } 60{,}000/\text{day}$.

$$\text{Prolongation cost} = 18 \text{ days} \times \text{NRs } 60{,}000/\text{day} = \text{NRs } 1{,}080{,}000$$

Final answer: Prolongation (time-related) cost claim = NRs 1,080,000, together with an Extension of Time of 18 days.

Two procedural conditions for a valid claim

1. Notice within the time bar – The contractor must give written notice to the Engineer within 28 days of becoming aware (or of when he should have become aware) of the event; otherwise the claim may be time-barred.
2. Contemporaneous records & detailed particulars – The contractor must keep contemporary records and submit a fully detailed claim (with substantiation of time and cost) within the period required (typically 42 days) under the contract.

Arbitration

Arbitration is a private, binding method of dispute resolution in which the parties refer their dispute to one or more impartial arbitrators (an arbitral tribunal), who hear the matter and issue an arbitral award that is final and enforceable like a court decree.

Arbitration vs Litigation

The ADR ladder in construction contracts

Disputes are escalated step-by-step, using the least adversarial method first:

1. Negotiation – Direct, good-faith discussion between the parties' representatives.
2. Mediation/Conciliation – A neutral third party facilitates a non-binding settlement.
3. Adjudication / Dispute Adjudication Board (DAB/DAAB) – A standing or ad-hoc board gives a binding-unless-revised decision quickly to keep the project moving.
4. Arbitration – If the DAB decision is contested (notice of dissatisfaction), the dispute proceeds to binding arbitration.

Negotiation -> Mediation -> Adjudication/DAB -> Arbitration
  (informal)   (non-binding)  (interim binding)   (final binding)

Salient features under the Arbitration Act 2055 (Nepal)

• Applies where a written arbitration agreement exists between the parties.
• Parties may appoint arbitrators; default is three arbitrators unless agreed otherwise; provision for a single arbitrator/umpire.
• The arbitrator must decide within the statutory period (the Act prescribes a time limit, generally 120 days from submission of documents, extendable).
• The award must be in writing, reasoned, signed and dated.
• Limited grounds to challenge/void an award before the court (e.g., excess of jurisdiction, denial of natural justice, fraud).
• The award is executable through the court like a decree.

Conclusion: Arbitration offers a faster, private, expert and final route compared with litigation, and sits at the top of the construction ADR ladder, backed in Nepal by the Arbitration Act 2055.

Public-Private Partnership (PPP)

PPP is a long-term contractual arrangement between a public authority and a private party in which the private party assumes substantial financing, design, construction, operation and risk responsibilities for a public infrastructure asset or service, with returns linked to performance.

Rationale for Nepal

• Bridges the financing gap — public budgets cannot meet large infrastructure needs (roads, hydropower, airports).
• Brings private efficiency, technology and management.
• Transfers risk (construction, operation, demand) to parties best able to manage it.
• Whole-life accountability — same party builds and operates, incentivising quality.

Common PPP modalities

Advantages and risks

Advantages: mobilises private capital; faster delivery; efficiency & innovation; risk sharing; reduces fiscal burden; lifecycle quality.

Risks: demand/traffic risk (revenue shortfall); construction cost & time overrun; political/regulatory risk; currency & financing risk; high transaction & contract complexity; affordability (high tolls/tariffs to users).

Numerical: simple payback period of BOT toll road

Given:

• Investment $I = \text{NRs } 4{,}000$ million
• Concession period $= 20$ years
• Average daily traffic (ADT) $= 8{,}000$ vehicles
• Toll $= \text{NRs } 150$ per vehicle
• Annual O&M cost $= \text{NRs } 200$ million

Step 1 — Annual gross toll revenue:

$$R = 8{,}000 \times 150 \times 365 = \text{NRs } 438{,}000{,}000 = \text{NRs } 438 \text{ million/year}$$

Step 2 — Annual net cash flow (after O&M):

$$NCF = 438 - 200 = \text{NRs } 238 \text{ million/year}$$

Step 3 — Simple payback period:

$$T_{pb} = \frac{I}{NCF} = \frac{4{,}000}{238} \approx 16.81 \text{ years}$$ $$T_{pb} \approx 16.8 \text{ years} \;(\approx 16 \text{ years } 10 \text{ months})$$

Final answer: Simple payback period ≈ 16.8 years.

Comment: Since the payback period (≈ 16.8 years) is less than the 20-year concession period, the developer can recover the investment with about 3.2 years of concession remaining to earn a return. The project is therefore financially recoverable, but the modest margin means it is sensitive to traffic/toll shortfalls and cost overruns — careful demand-risk allocation is essential.

Nepal Engineering Council (NEC)

The Nepal Engineering Council is the statutory regulatory body established under the Nepal Engineering Council Act 2055 (1999) to regulate the engineering profession in Nepal.

Objectives

• To make the engineering profession systematic, dignified and accountable.
• To maintain professional standards and protect the public.
• To regulate the qualification and conduct of engineers.

Major functions

1. Registration / licensing of qualified engineers and issuance of the registration certificate.
2. Recognition / accreditation of engineering qualifications and academic programmes/institutions.
3. Maintaining the register of engineers (categories such as Registered Engineer, Professional Engineer).
4. Prescribing and enforcing the Code of Ethics / professional conduct.
5. Taking disciplinary action (warning, suspension, removal from register) against misconduct.
6. Advising the government on engineering education and practice.

Registration requirement

• No person may practise engineering or use the title "Engineer" in Nepal without registration with NEC.
• Registration requires a recognised engineering degree/diploma in the relevant discipline.
• A registered engineer obtains a registration (NEC) number, must abide by the Code of Ethics, and renew the registration as prescribed.

Significance: NEC registration is the legal licence to practise; it safeguards public safety by ensuring only qualified, accountable persons sign and certify engineering works.

Intellectual Property Rights (IPR)

Intellectual property refers to creations of the mind for which exclusive legal rights are granted to the creator/owner for a limited period.

Main types relevant to engineers

Why it matters to engineers

• Protects innovations and rewards R&D investment.
• Engineers must respect others' IPR (e.g., not copy patented designs or licensed software illegally).
• Clarifies ownership of designs created for an employer/client (usually via contract).

Protection in Nepal

• The principal law is the Patent, Design and Trademark Act 2022 (1965), administered by the Department of Industry, covering patents, industrial designs and trademarks.
• Copyright is protected under the Copyright Act 2059 (2002), administered by the Nepal Copyright Registrar's Office.
• Nepal is a member of WIPO and the WTO/TRIPS framework, aligning protection with international norms.

Conclusion: Understanding and respecting patents, copyrights, trademarks and trade secrets allows engineers to protect their own innovations and avoid infringement liability.

Engineers, society and the environment

Engineering shapes the built environment and directly affects quality of life, safety, the economy and ecosystems. With this influence comes a broad social responsibility.

Responsibility towards society

• Public safety & welfare first — hold public health, safety and welfare paramount.
• Competence & honesty — perform services only in areas of competence; provide truthful, objective statements.
• Affordability & accessibility — design infrastructure that serves the wider community, including disadvantaged groups.
• Public awareness — inform the public and authorities of risks and consequences.

Responsibility towards the environment

• Minimise pollution, resource depletion and ecological damage.
• Conduct/comply with Environmental Impact Assessment (EIA) and Initial Environmental Examination (IEE) as required by law.
• Promote energy efficiency, waste reduction, recycling and use of green materials.

Sustainable development

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland definition). It rests on three pillars:

        SUSTAINABILITY
      /       |        \
 Economic  Social   Environmental
 (viable) (equitable) (bearable)

Engineer's duty in sustainability

• Adopt whole-life-cycle thinking (design, construction, operation, decommissioning).
• Use resources efficiently; reduce carbon footprint.
• Design for resilience (e.g., earthquake- and climate-resilient infrastructure).
• Balance economic feasibility with social equity and environmental protection.

Conclusion: Engineers are stewards of public well-being and the environment; embedding sustainability into every project is a core professional responsibility.

Liquidated damages vs penalty

Liquidated damages (LD) are a genuine pre-estimate of the loss the employer will suffer due to the contractor's delay, agreed in advance and written into the contract. They are recoverable without proof of actual loss.

Penalty is a sum disproportionate to the likely loss, intended to punish/deter breach. Penalties are generally not enforceable; courts only allow recovery of genuine loss.

Numerical: liquidated damages

Given: Contract price $P = \text{NRs } 50{,}000{,}000$; delay $= 12$ days; LD rate $= 0.05\%$ of $P$ per day; cap $= 10\%$ of $P$.

Step 1 — LD per day:

$$LD_{day} = 0.0005 \times 50{,}000{,}000 = \text{NRs } 25{,}000/\text{day}$$

Step 2 — LD for 12 days:

$$LD = 25{,}000 \times 12 = \text{NRs } 300{,}000$$

Step 3 — Check against cap:

$$\text{Cap} = 0.10 \times 50{,}000{,}000 = \text{NRs } 5{,}000{,}000$$

Since $\text{NRs } 300{,}000 < \text{NRs } 5{,}000{,}000$, the LD is within the cap.

Final answer: Liquidated damages = NRs 300,000, which is within the NRs 5,000,000 (10%) cap.

Whistleblowing

Whistleblowing is the act by which an employee/engineer discloses, to an authority or the public, information about serious wrongdoing, unsafe practice, fraud or illegal conduct within an organisation, when internal channels fail or are inappropriate.

• Internal whistleblowing – reporting to higher management within the organisation.
• External whistleblowing – reporting to regulators, NEC, media or the public.

When is it ethically justified?

Whistleblowing is generally considered justified (and may even be obligatory) when:

1. There is serious, identifiable harm to public safety, health, welfare or the environment.
2. The engineer has reported the concern internally and management failed to act.
3. There is strong, documented evidence of the wrongdoing.
4. Going public has a reasonable chance of preventing or correcting the harm.
5. The harm prevented outweighs the personal and organisational cost.

Precautions before blowing the whistle

• Verify the facts and gather objective, contemporaneous evidence.
• Exhaust internal channels first and keep written records of reports.
• Act in good faith, not from malice or personal gain.
• Seek advice (NEC, legal counsel, professional body).
• Follow proper/legal channels and whistleblower-protection provisions where available.

Conclusion: Whistleblowing reflects the engineer's paramount duty to public safety, but it must be a measured, evidence-based, last-resort action taken responsibly.

Numerical: bid evaluation

Given: Engineer's estimate $E = \text{NRs } 12{,}000{,}000$.

Percentage deviation $= \dfrac{\text{Bid} - E}{E} \times 100\%$ (negative = below estimate).

Bidder A:

$$\frac{10{,}800{,}000 - 12{,}000{,}000}{12{,}000{,}000}\times 100 = \frac{-1{,}200{,}000}{12{,}000{,}000}\times 100 = -10\%\;(\textbf{10\% below})$$

Bidder B:

$$\frac{11{,}520{,}000 - 12{,}000{,}000}{12{,}000{,}000}\times 100 = \frac{-480{,}000}{12{,}000{,}000}\times 100 = -4\%\;(\textbf{4\% below})$$

Bidder C:

$$\frac{13{,}200{,}000 - 12{,}000{,}000}{12{,}000{,}000}\times 100 = \frac{+1{,}200{,}000}{12{,}000{,}000}\times 100 = +10\%\;(\textbf{10\% above})$$

Lowest bid: Bidder A at NRs 10,800,000. Provided A passes the preliminary and technical (responsiveness) checks, A is the lowest substantially responsive bid and is recommended for award.

Final answer: A = 10% below, B = 4% below, C = 10% above; lowest substantially responsive bid = Bidder A (NRs 10,800,000).

Abnormally low bid

An abnormally low bid is one that is so far below the engineer's estimate (or below the other bids) that the procuring entity reasonably doubts the bidder's ability to perform the contract at that price.

Why it is a concern:

• The bidder may have underestimated costs, risking abandonment or default.
• It can lead to poor quality, cutting corners, or excessive claims/variations later.
• The procuring entity may demand justification/clarification and, if not satisfied, may reject the bid and/or require enhanced performance security.

(Here A at 10% below estimate is competitive but not necessarily abnormal; the procuring entity should still confirm A's rates and capacity before award.)
