BE Civil Engineering (IOE, TU) Engineering Professional Practice (IOE, CE 753) Question Paper 2078 Nepal

(a) Four fundamental canons (6 marks)

Most engineering codes of conduct (NEC, NSPE, FIDIC professional codes) open with a small set of fundamental canons. A representative set:

1. Hold paramount the safety, health and welfare of the public. The engineer must place public protection above client wishes, employer pressure or personal gain.
2. Perform services only in areas of competence. An engineer should only undertake work matching their qualifications and experience, and should engage specialists where needed.
3. Issue public statements in an objective and truthful manner. Reports, testimony and certifications must be honest, complete and free of misrepresentation.
4. Act for each employer or client as a faithful agent or trustee, and avoid conflicts of interest. Confidentiality, loyalty and disclosure of conflicts are required; the engineer must not accept secret commissions.

Additional canons in many codes: conduct oneself honorably and lawfully, and continue professional development.

Why public safety is first: Engineering works (bridges, buildings, dams, water systems) directly affect the life and property of people who have no say in design decisions and cannot evaluate the risk themselves. When obligations conflict — a cheaper or faster option versus a safer one — the canon ordering tells the engineer which duty wins. Placing public welfare first makes it a non-negotiable constraint, not one interest to be balanced against profit or schedule. It also reflects the social contract: society grants engineers a near-monopoly (licensure, NEC registration) in exchange for the profession self-policing in the public interest.

(b) Structured ethical decision making for the sub-strength concrete (4 marks)

The delivered concrete is at $18\ \text{MPa}$, only $18/25 = 72\%$ of the specified strength — a clear public-safety issue. Steps:

1. Gather and verify the facts. Confirm the test results (sampling, curing, lab procedure), check how many pours are affected and which structural elements received the concrete.
2. Identify the ethical issue and stakeholders. Public safety (canon 1) versus loyalty to employer/schedule (canon 4); stakeholders are end users, the client, the public, the firm.
3. Refer to the controlling standards and contract. Specification $M25$, the code of conduct, NEC rules, and the contract's quality clauses make acceptance of $18\ \text{MPa}$ a violation.
4. Consider alternatives. Reject the lot; require core testing / load testing of placed elements; demand remedial work or demolition where strength is inadequate; document everything in writing.
5. Decide and act, refusing the unethical instruction. The engineer must not sign off. Report formally to the PM in writing, escalate to the design consultant/employer, and if overruled, escalate further (firm management, then NEC). Refusing to certify defective work is mandated, not optional.
6. Document and follow up to ensure correction, protecting both the public and the engineer's professional standing.

(a) Types of tender (4 marks)

• Open (competitive) tender: Advertised publicly; any qualified contractor may bid. Maximises competition and transparency; used for most public works above a threshold. Slower and costlier to administer.
• Selective / limited tender: Bids invited only from a pre-qualified or shortlisted list of contractors. Used for specialised or high-risk works where only a few firms are capable, or for medium-value works to save evaluation effort.
• Negotiated tender: Client negotiates directly with one (or very few) contractor(s) without full competition. Used in emergencies, where there is a sole source, for extension of existing work, or where secrecy/specialist skill is essential. Least transparent, so it is tightly restricted under procurement law.

(b) Combined evaluation (6 marks)

Lowest price $P_{\min} = 420$ (Bidder B).

Price scores $= \dfrac{420}{P_i}\times 100$:

• A: $\dfrac{420}{480}\times100 = 87.50$
• B: $\dfrac{420}{420}\times100 = 100.00$
• C: $\dfrac{420}{450}\times100 = 93.33$

Combined score $S = 0.70\,(\text{price}) + 0.30\,(\text{technical})$:

• A: $0.70(87.50) + 0.30(85) = 61.25 + 25.50 = \mathbf{86.75}$
• B: $0.70(100.00) + 0.30(70) = 70.00 + 21.00 = \mathbf{91.00}$
• C: $0.70(93.33) + 0.30(92) = 65.33 + 27.60 = \mathbf{92.93}$

Recommendation: Bidder C has the highest combined score (92.93) and, provided the bid is substantially responsive and within the cost estimate, should be recommended for award. Although B is the cheapest, C's strong technical score outweighs its modest price premium under the 70/30 weighting.

(a) Red, Yellow and Silver Books (4 marks)

Moving Red → Yellow → Silver shifts design responsibility and risk progressively from Employer to Contractor, and price certainty increases for the Employer.

(b) Role of the Engineer and EOT time-bar (4 marks)

Role of the Engineer (Red Book): The Engineer is appointed by the Employer to administer the contract — issue drawings and instructions, supervise, measure work, certify payments (Interim Payment Certificates), and determine claims and variations. The Engineer is not a party to the contract but must act fairly/impartially when making determinations, balancing both parties, even though paid by the Employer.

Extension of Time (EOT) time-bar procedure:

1. On becoming aware (or when he should have become aware) of an event giving rise to delay, the Contractor gives a notice to the Engineer.
2. The notice must be given within 28 days of the Contractor becoming aware of the event/circumstance (Sub-Clause 20.1 in the 1999 edition; 28-day Notice in the 2017 edition).
3. The Contractor then submits, within a further period (commonly 42 days), a fully detailed claim with supporting particulars and contemporary records.
4. The Engineer responds, agrees or determines the EOT.

If the notice is missed: Failure to give notice within the 28-day period bars the claim — the Time for Completion is not extended and the Contractor loses the right to that EOT (and may become liable for delay damages). This "condition precedent" forces prompt notification so the Engineer can investigate while evidence is fresh.

(a) BOT model (4 marks)

BOT (Build–Operate–Transfer): A private concessionaire finances, builds and operates an infrastructure asset for a fixed concession period, recovering its investment and profit from user charges/tariffs (here, sale of electricity), then transfers the asset to the government at the end of the concession.

Variants:

• BOOT (Build-Own-Operate-Transfer): Concessionaire owns the asset during the concession, then transfers.
• BOO (Build-Own-Operate): No transfer; the private party retains ownership permanently.
• DBFO (Design-Build-Finance-Operate): Adds explicit design and financing roles, common for roads.

Advantages to the public sector: Mobilises private capital (no upfront government funding); transfers construction, operation and financing risk to the private party; brings private-sector efficiency and technology; the asset reverts to the state for free at concession end.

Risks borne by the concessionaire: Construction cost/time overrun, hydrology/resource risk, market/demand and tariff risk, foreign-exchange and interest-rate risk, regulatory and political risk, and operation & maintenance risk over the long concession.

(b) NPV of equity (4 marks)

Given: equity outflow $= 4{,}500$ lakh at year 0; annual net cash flow $A = 720$ lakh for 25 years; $i = 12\%$; $(P/A,12\%,25) = 7.8431$.

Present value of inflows:

$$PV = A\times(P/A,12\%,25) = 720 \times 7.8431 = 5{,}647.03\ \text{lakh}$$

Net Present Value:

$$NPV = PV - \text{Initial equity} = 5{,}647.03 - 4{,}500 = \mathbf{1{,}147.03\ \text{lakh}}$$

Benefit–cost check: $\dfrac{5647.03}{4500} = 1.25 > 1$.

Conclusion: Since $NPV = +1{,}147.03$ lakh $> 0$ (and the discounted benefit/cost ratio is $1.25$), the project earns more than the $12\%$ required return and is financially attractive to the concessionaire.

(a) Comparison of dispute resolution methods (5 marks)

The ADR methods (arbitration, mediation, adjudication) are favoured in construction because they are faster, private, allow technically expert decision-makers, and preserve commercial relationships.

(b) Arbitration agreement and proceeding (4 marks)

Essential features of a valid arbitration agreement:

• It must be in writing (typically an arbitration clause within the main contract or a separate submission agreement).
• It must show a clear intention to refer disputes to arbitration (a defined scope of disputes covered).
• The dispute must be arbitrable (capable of settlement by arbitration; not, e.g., criminal matters).
• Parties must have capacity and give free consent.
• It commonly states the number of arbitrators, appointment method, seat/venue, language and applicable rules.

Broad stages under Nepal's Arbitration Act, 2055 (1999):

1. Invocation / notice of arbitration by the aggrieved party referring the dispute.
2. Appointment of arbitrator(s) as per the agreement (sole or panel of three); the court/appointing authority assists if parties fail to agree.
3. Pleadings — submission of claim (statement of claim) and reply/counterclaim.
4. Hearings and evidence — documents, witnesses, expert evidence; the tribunal follows agreed/statutory procedure and natural justice (both parties heard).
5. Deliberation and the arbitral award — a reasoned, written, signed decision, normally to be rendered within the time fixed by the Act.
6. Enforcement / challenge — the award is binding and enforceable like a court decree; it may be set aside only on limited statutory grounds (e.g. lack of jurisdiction, denial of natural justice, public policy).

Nepal Engineering Council (NEC):

• Legal basis: A statutory body established under the Nepal Engineering Council Act, 2055 (1998), with the Council and its regulations governing the engineering profession.
• Main functions:

1. Registration of engineers — maintaining the register of qualified engineers and issuing registration/licence (NEC number).
2. Recognition / accreditation of engineering qualifications and institutions whose degrees are acceptable for registration.
3. Setting and enforcing a code of ethics / professional conduct, and taking disciplinary action (suspension or removal from the register) against misconduct.
4. Regulating engineering practice and advising government on engineering education and policy; conducting the registration/licensing examination.

• Why registration is mandatory: It is a legal requirement to practise as an engineer — only registered engineers may sign and certify engineering work, hold responsible engineering posts, and submit designs to authorities. Mandatory registration ensures minimum competence, accountability and ethical conduct, protecting the public from unqualified practitioners. Practising without registration is an offence.

Intellectual property (IP): Legal rights over creations of the human mind — inventions, literary and artistic works, designs, symbols and names used in commerce. IP gives the creator a time-limited exclusive right to use/exploit the creation, encouraging innovation while eventually enriching the public domain.

Key distinctions: A patent protects the functional idea/invention (and requires disclosure + registration); copyright protects the expression, not the idea, and arises automatically on creation; a trademark protects brand identity in the marketplace and lasts as long as it is used and renewed.

Essential elements of a valid contract:

1. Offer and acceptance — a definite proposal by one party and unqualified acceptance by the other (consensus / meeting of minds).
2. Lawful consideration — something of value exchanged by each party.
3. Capacity of parties — parties must be competent (of age, sound mind, not legally disqualified).
4. Free consent — agreement free from coercion, undue influence, fraud, misrepresentation or mistake.
5. Lawful object — the purpose must be legal and not against public policy.
6. Intention to create legal relations and certainty of terms; legal formalities (writing/registration) where required.

Void or voidable situations (any two):

• A contract whose object is illegal (e.g. to do something prohibited by law) is void.
• A contract entered into by a person without capacity (e.g. a minor) is void/voidable.
• Consent obtained by fraud, coercion, undue influence or misrepresentation makes the contract voidable at the option of the aggrieved party.
• An agreement based on a mutual mistake of fact essential to the contract is void.

Engineer's responsibilities to society and the environment:

• Design and build works that are safe and serve the genuine needs of the community.
• Minimise adverse environmental impact — pollution, deforestation, resource depletion — and comply with environmental laws (e.g. IEE/EIA requirements).
• Use resources efficiently (materials, energy, water) and consider the whole life-cycle of the project.
• Be truthful with the public, involve affected communities, and respect their welfare and rights over short-term profit.
• Consider the needs of future generations, not only present users.

Sustainable development: Development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland definition).

Three pillars (in an engineering project):

1. Economic — the project must be financially viable and deliver value for money.
2. Social — it must be equitable, safe, and improve community well-being and livelihoods.
3. Environmental — it must protect ecosystems, limit emissions/waste, and conserve natural resources.

A sustainable project balances all three so that economic gains do not come at unacceptable social or environmental cost.

Bid security vs performance security:

Computation of performance security:

$$\text{Performance security} = 5\% \times 6{,}000\ \text{lakh} = 0.05 \times 6{,}000 = \mathbf{300\ \text{lakh}}$$

Release: The performance security is typically returned to the contractor after satisfactory completion of the works and expiry of the defect liability / maintenance period (or it is reduced to a retention/warranty amount at substantial completion).

Conflict of interest: A situation in which an engineer's personal interest (financial or otherwise) could improperly influence, or appear to influence, professional judgment made on behalf of a client or employer. The engineer's duty to act as a faithful agent is compromised.

Examples (any two):

• An engineer who owns shares in / is paid commission by the material supplier they are approving on a project.
• An engineer who checks/approves their own design without independent review, or reviews a relative's tender.
• Accepting gifts or hospitality from a contractor whose work the engineer is supervising.

The correct response is disclosure of the conflict and withdrawal from the affected decision.

Whistleblowing: An employee/engineer disclosing to authorities or the public serious wrongdoing, illegal acts, or threats to public safety that the organisation is concealing.

Conditions under which it is ethically justified (commonly):

1. There is serious and considerable harm to the public (safety, health, environment).
2. The engineer has reported the concern internally through proper channels first and it was ignored.
3. The engineer has reasonable, documented evidence that a reasonable person would find convincing.
4. There is good reason to believe that going public will help prevent the harm.

When these are met, the duty to public safety overrides loyalty to the employer.
