Professional Ethics

Professional ethics is the set of moral principles, standards of conduct, and values that govern the behaviour of members of a profession in the exercise of their professional duties. For engineers it defines the obligations owed to the public, the client/employer, the profession, and to fellow practitioners.

Why a formal code of ethics is essential

1. Protection of public welfare — engineering decisions affect safety of life and property; a code makes public safety a non-negotiable priority.
2. Uniform standard of conduct — provides a common benchmark so that all members behave consistently and predictably.
3. Guidance in dilemmas — gives a reference framework when commercial and ethical pressures conflict.
4. Public trust and credibility — assures society and clients that engineers act competently and honestly.
5. Basis for accountability/discipline — bodies such as the Nepal Engineering Council (NEC) can sanction violations only against a written standard.
6. Professional self-regulation — justifies the autonomy granted to the profession.

Four fundamental canons

1. Hold paramount the safety, health and welfare of the public — the overriding obligation.
2. Perform services only in areas of competence — undertake assignments only when qualified.
3. Act as faithful agents/trustees for each employer or client — including confidentiality and disclosure/avoidance of conflicts of interest.
4. Conduct themselves honourably, responsibly, ethically and lawfully — sustaining the honour and dignity of the profession; objective and truthful statements.

Case analysis — paramountcy of public safety

Ethical conflicts identified:

The sub-standard concrete in a critical bridge pier directly threatens public safety, so the canon hold paramount the safety, health and welfare of the public dominates all other considerations. The offered bonus is effectively a bribe and must be refused.

Recommended step-by-step course of action:

1. Reject the pour immediately — do not approve sub-standard material; document the decision.
2. Refuse the bonus in writing; it constitutes a conflict of interest / inducement.
3. Test and record — take core/cube samples and lab test reports as objective evidence of the deficiency.
4. Notify the client/consultant in writing — the engineer is a faithful agent of the client, who must be informed.
5. Issue a non-conformance report / instruct rework per the contract (e.g., reject and replace the material, demolish if already placed).
6. Escalate to superiors/employer if pressure continues; if the issue is suppressed, report to the relevant authority (NEC / regulatory body).
7. Maintain confidentiality of proprietary information but never at the cost of public safety.

The ethically correct outcome: the defective concrete is not used, the client is informed, the inducement is refused, and public safety is protected even at the cost of schedule delay.

Essential elements of a valid contract

1. Offer and acceptance — a clear proposal accepted unconditionally.
2. Intention to create legal relations.
3. Lawful consideration — something of value exchanged.
4. Capacity of parties — competent (age of majority, sound mind, not disqualified).
5. Free consent — free of coercion, undue influence, fraud, misrepresentation, mistake.
6. Lawful object — purpose not illegal/immoral/against public policy.
7. Certainty and possibility of performance.
8. Not expressly declared void.

Stages of competitive tendering (public project, Nepal)

1. Procurement planning & cost estimate (engineer's estimate, per Public Procurement Act/Rules).
2. Invitation for Bids / Notice — public advertisement (National/International Competitive Bidding).
3. Issue / sale of bidding documents (or e-GP download).
4. Pre-bid meeting & clarifications / addenda.
5. Submission of bids with bid security before deadline.
6. Bid opening in public at the appointed time.
7. Bid evaluation — preliminary examination (responsiveness), arithmetic correction, detailed/technical & financial evaluation.
8. Identification of the lowest evaluated substantially-responsive bid.
9. Award recommendation & approval by competent authority.
10. Notification / Letter of Acceptance and performance security.
11. Contract agreement signing.

Bid evaluation

Step 1 — Responsiveness: Bidder B is rejected (no bid security = non-responsive). Only A, C, D are evaluated.

Step 2 — Apply arithmetic corrections (evaluated price):

Step 3 — Lowest evaluated: A and C are tied at NRs 46,500,000, both below D.

With a tie, the bidder whose read-out (quoted) price was lower — Bidder C (NRs 45,800,000 quoted) — is conventionally ranked first as the lowest evaluated responsive bid; alternatively a tie-breaking rule per the bidding document applies. Taking the lowest quoted of the tied pair:

Winner: Bidder C, evaluated price NRs 46,500,000.

Step 4 — Percentage below engineer's estimate (on corrected/evaluated price):

$$\text{\% below} = \frac{50{,}000{,}000 - 46{,}500{,}000}{50{,}000{,}000}\times 100 = \frac{3{,}500{,}000}{50{,}000{,}000}\times 100 = 7.0\%$$

Contract awarded to Bidder C at evaluated price NRs 46,500,000, which is 7.0% below the engineer's estimate.

FIDIC

FIDIC = Fédération Internationale des Ingénieurs-Conseils (International Federation of Consulting Engineers), based in Geneva. It publishes internationally recognised standard forms of contract that allocate risk fairly between parties and are widely used (often required by multilateral lenders) for construction and engineering works.

Purpose of the FIDIC suite

• Provide balanced, tested, standard conditions so parties need not draft from scratch.
• Clear, fair allocation of risk between Employer and Contractor.
• Define roles, procedures, and dispute mechanisms consistently.
• Facilitate international tendering and lender acceptance.

Colour-coded books (structure)

Most FIDIC books share a two-part structure: General Conditions (standard clauses) and Particular Conditions (project-specific amendments/data).

Role of the Engineer (Red Book)

• Administers the contract on behalf of the Employer but, in certain functions, must act fairly/impartially when making a determination between the parties.
• Issues instructions, approves drawings, certifies interim and final payments, certifies completion, evaluates variations and claims, and makes determinations on time/cost.

Role of the DAB / DAAB

• A standing or ad-hoc board (1 or 3 members) appointed early in the contract.
• Avoids disputes (informal assistance) and adjudicates disputes referred to it, issuing a decision that is binding unless/until revised by amicable settlement or arbitration.
• Acts as the first formal tier of dispute resolution before arbitration, keeping the project running.

Procedure for a Contractor's claim (time & cost)

1. Notice of claim — the Contractor must give written notice as soon as practicable, and not later than 28 days after becoming aware (or should have become aware) of the event/circumstance. Failure within this period is a time-bar: the claim may be lost (Employer discharged from liability).
2. Keep contemporary records of the event and its effects.
3. Fully detailed claim — submit a detailed substantiation (basis, EOT and/or additional payment claimed) within the period stated (commonly 42 days of awareness).
4. Engineer's response/determination — the Engineer responds (approve/disapprove with reasons) and makes a fair determination of any extension of time and additional cost.
5. If unresolved, the dispute is referred to the DAB/DAAB, then (if dissatisfied) to amicable settlement and finally arbitration.

Key takeaway: the 28-day notice time-bar is critical — a substantively valid claim can still fail purely for late notice.

Methods of dispute resolution (comparison)

A typical FIDIC/construction escalation ladder: negotiation → mediation/adjudication (DAB) → arbitration → (court enforcement).

Arbitration under the Arbitration Act, 2055 BS (Nepal)

Arbitration is a private, consensual method in which parties refer their dispute to one or more impartial persons (arbitrators) whose award is final and binding, instead of going to court.

Arbitration agreement

• A written agreement by which parties agree to submit present or future disputes to arbitration.
• May be a clause within the main contract or a separate agreement.
• Once a valid agreement exists, courts generally decline jurisdiction and refer parties to arbitration.

Arbitral tribunal

• Constituted by the number of arbitrators agreed (commonly one or three; if three, each party appoints one and the two appoint the presiding arbitrator).
• Must be independent and impartial; can be challenged for justifiable doubts as to impartiality.
• Has power to rule on its own jurisdiction, decide procedure, take evidence, and grant interim measures.

Key features / procedure

1. Reference of dispute per the arbitration agreement.
2. Appointment of tribunal (court may assist if parties fail).
3. Hearings — parties present pleadings, evidence, arguments; rules of natural justice apply.
4. Award in writing, signed, with reasons, within the statutory/agreed time.

Finality & enforceability of the award

• The award is final and binding on the parties.
• Grounds to challenge/set aside are limited (e.g., invalid agreement, lack of jurisdiction, denial of natural justice, award against public policy, fraud) and must be raised before the court within the statutory period (commonly 35 days).
• A confirmed award is enforced like a court decree; foreign awards are enforceable under the New York Convention to which Nepal is a party.

Advantages of arbitration in construction: technical expertise of arbitrators, confidentiality, party autonomy over procedure, speed relative to courts, and international enforceability — making it the preferred final-tier mechanism in major contracts.

Public-Private Partnership (PPP)

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 or services, sharing risks and rewards, with payment tied to performance or user charges.

Rationale for Nepal

• Bridges the infrastructure financing gap (limited public budget vs. large needs).
• Brings private capital, technology, managerial efficiency.
• Risk transfer to the party best able to manage it.
• Faster delivery and better life-cycle asset management.
• Governed in Nepal by the PPP and Investment Act / Investment Board Act framework.

Common PPP models

Advantages and risks

Advantages: off-budget financing, efficiency, innovation, risk sharing, timely completion, improved O&M.

Risks: construction/cost-overrun risk, demand/traffic risk, financing & interest-rate risk, political/regulatory risk, currency risk, contract complexity, and risk of higher user charges.

BOT toll-road financial analysis

Given: Construction cost $C =$ NRs 4,000 million; period $= 20$ years; traffic $= 15{,}000$ veh/day; toll $=$ NRs 120/veh; O&M $=$ NRs 250 million/yr; toll days $= 350$/yr.

(i) Total gross toll revenue

Annual revenue:

$$R_{yr} = 15{,}000 \times 120 \times 350 = \text{NRs } 630{,}000{,}000 = \text{NRs } 630\text{ million/yr}$$

Over 20 years:

$$R_{total} = 630 \times 20 = \textbf{NRs } 12{,}600\textbf{ million}$$

(ii) Total O&M cost

$$OM_{total} = 250 \times 20 = \textbf{NRs } 5{,}000\textbf{ million}$$

(iii) Net surplus after recovering construction cost

$$\text{Net surplus} = R_{total} - OM_{total} - C$$ $$= 12{,}600 - 5{,}000 - 4{,}000 = \textbf{NRs } 3{,}600\textbf{ million}$$

Viability: Since the net surplus is positive (NRs 3,600 million), the project recovers its construction and O&M costs and yields a surplus, so on a simple (undiscounted) basis it is financially viable. (Note: a rigorous appraisal would discount cash flows to NPV and check the IRR against the cost of capital.)

Nepal Engineering Council (NEC)

Establishment: A statutory autonomous body constituted under the Nepal Engineering Council Act, 2055 BS (1999) to regulate the engineering profession in Nepal.

Objectives

• Maintain professional standards, discipline and quality in engineering practice.
• Protect public interest by ensuring only qualified persons practise engineering.

Major functions

1. Registration of qualified engineers and maintaining the register.
2. Recognition/accreditation of engineering degrees and institutions.
3. Conducting the licensing (registration) examination.
4. Issuing the engineering licence / registration certificate and the seal/registration number.
5. Prescribing and enforcing a code of ethics/professional conduct; taking disciplinary action (suspension/removal) for misconduct.
6. Advising government on engineering education and practice policy.

Significance of registration & licensing examination

• It is mandatory — no person may use the title "engineer" or practise/sign engineering documents without NEC registration.
• The licensing examination verifies minimum competence beyond the academic degree.
• Registration creates accountability: a registered engineer can be disciplined for negligence or ethical breaches, thereby protecting public safety and the credibility of the profession.

Thus the NEC functions as the regulatory and licensing authority that safeguards quality and ethics in Nepalese engineering practice.

Intellectual Property (IP)

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

Types of IP

Key distinctions

• A patent requires public disclosure in exchange for a monopoly; a trade secret relies on secrecy and has no fixed term but no protection once disclosed.
• Copyright protects the expression (the drawing), not the underlying idea/function — which would need a patent.
• A trademark protects identity/brand, not the technical content.

Why IP matters to an engineer

• Protects the engineer's/firm's innovations and designs from unauthorised copying.
• Ensures the engineer respects others' rights (avoiding infringement and plagiarism — an ethical duty).
• Encourages innovation and R&D, and can be a source of revenue (licensing).
• Proper handling of clients' confidential information is part of the duty as a faithful agent.

In Nepal, IP is governed mainly by the Patent, Design and Trademark Act, 2022 BS and the Copyright Act, 2059 BS.

Liquidated damages vs. penalty

Liquidated damages (LD) are a sum pre-agreed in the contract as a genuine pre-estimate of the loss the employer will suffer from delayed completion. They are payable without the employer having to prove actual loss, and are usually expressed as an amount per day of delay, often capped at a percentage of the contract price.

Penalty is a sum fixed to punish/deter the defaulting party rather than to compensate genuine loss. It is typically disproportionate to the likely loss. Courts generally enforce liquidated damages but refuse to enforce penalties (a penalty clause may be struck down).

Calculation

Given: Contract price $P =$ NRs 80,000,000; LD rate $= 0.05\%$ of $P$ per day; cap $= 10\%$ of $P$; delay $= 65$ days.

Daily LD amount:

$$LD_{day} = 0.05\% \times 80{,}000{,}000 = 0.0005 \times 80{,}000{,}000 = \text{NRs } 40{,}000\text{/day}$$

LD for 65 days:

$$LD = 40{,}000 \times 65 = \text{NRs } 2{,}600{,}000$$

Cap (maximum):

$$LD_{max} = 10\% \times 80{,}000{,}000 = \text{NRs } 8{,}000{,}000$$

Check: NRs 2,600,000 < NRs 8,000,000, so the cap is not reached.

Liquidated damages payable = NRs 2,600,000. (The 10% cap, NRs 8,000,000, would only bind beyond 200 days of delay.)

Engineer's role and responsibilities towards society and environment

Engineers shape the built environment and therefore carry social responsibilities beyond their clients:

1. Public safety, health and welfare — the paramount obligation; design and build to protect lives and property.
2. Environmental stewardship — minimise pollution, resource depletion, and ecological damage; conduct/respect Environmental Impact Assessment (EIA/IEE).
3. Honesty and transparency with the public about risks and impacts.
4. Equity and inclusion — consider affected communities, displacement, and access.
5. Efficient use of public resources — value for money in public works.

Sustainable development

Sustainable development = "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." It balances three pillars: economic, social, and environmental.

Balancing development with environmental protection

• Adopt life-cycle thinking and select low-impact, durable, energy-efficient designs.
• Use EIA/IEE to identify and mitigate impacts before construction.
• Promote resource efficiency (recycling, local/green materials, water and energy conservation).
• Prefer renewable energy and climate-resilient/disaster-resilient design (important for Nepal's seismic and landslide-prone terrain).
• Involve stakeholders/communities and respect statutory environmental standards.

Thus an engineer serves society best by delivering needed infrastructure while safeguarding the environment for future generations — making sustainability a core professional and ethical duty.

Bid security vs. performance security

Calculation

Bid security $= 2.5\%$ of estimated cost:

$$BS = 0.025 \times 60{,}000{,}000 = \textbf{NRs } 1{,}500{,}000$$

Performance security $= 5\%$ of contract price:

$$PS = 0.05 \times 57{,}000{,}000 = \textbf{NRs } 2{,}850{,}000$$

Required bid security = NRs 1,500,000; required performance security = NRs 2,850,000.

Conflict of interest

A conflict of interest arises when an engineer has a personal, financial, or other interest that could improperly influence — or appear to influence — the objective performance of professional duties to a client, employer, or the public.

Example: A consulting engineer who must approve materials but secretly owns a share in the supplier company; or recommending a contractor who is a close relative.

Ethical guidance: Disclose the interest promptly and fully to all affected parties; recuse oneself from the decision; avoid accepting gifts/bribes; do not accept work where independent judgement is compromised. "Avoid all known or potential conflicts of interest."

Whistle-blowing

Whistle-blowing is the act of an engineer disclosing illegal, unethical, or dangerous conduct within an organisation to those who can correct it (internally, or externally to an authority/public) when internal channels fail.

Example: An engineer reports to the regulator that the employer is concealing structural defects in a public building that endanger occupants.

Ethical guidance: First raise the concern internally through proper channels and document it; ensure the facts are accurate and motivated by public safety, not malice; escalate externally only when internal remedies fail and the public is at risk. Because public safety is paramount, justified whistle-blowing is an ethical duty, and the engineer should be protected from retaliation.
