5.2.1 Definition of Contract 2078 2076

"All contracts are agreements but all agreements are not contracts."

Agreement + Legality = Contract

An agreement is the acceptance of the offer (proposal) with or without any condition. It may not have a legal obligation. But a contract is an agreement concluded between two or more parties for performing or not performing any work with legal enforceability.

ANSWER: What is contract and what are its essential elements? Explain how it is important in any large scale construction project? [4+2] (2078 Kartik)

Definition: As per Contract Act 2056, "Contract is an agreement between two or more persons to do or not to do something, which can be enforced by law."

Essential Elements of a Valid Contract:

  1. Offer and Acceptance: A valid proposal by one party and acceptance by another
  2. Consideration: Something of value exchanged between contracting parties
  3. Capacity to contract: All parties must be competent (not minors, insane, etc.)
  4. Lawful purpose: Contract must not be illegal
  5. Possibility of performance: Must be physically possible to perform
  6. Free consent: No coercion, fraud, undue influence, or deceit
  7. Certainty: Terms must be clear, not vague or ambiguous
  8. Legal relationship: Clear intention of parties with necessary documents
  9. Written form: Verbal agreement cannot be a contract
  10. Two or more competent parties

Importance in large scale construction projects:

  • Defines quantity and quality of work to be done
  • Defines time frame for completion and payment
  • Sets courses of action if either party fails to perform
  • Specifies responsibilities to parties and third parties
  • Provides legal protection and remedies for breach
  • Reduces disputes by establishing clear terms
ANSWER: "All contracts are agreements but all agreements are not contracts" — Justify [3] (2079 Jestha)
  • Agreement = acceptance of an offer/proposal, with or without conditions; may not have legal obligation
  • Contract = agreement concluded between two or more parties for performing/not performing work, enforceable by law
  • Agreement + Legality = Contract
  • Every contract is an agreement because it involves offer and acceptance
  • But NOT every agreement is a contract — only those with legal enforceability qualify
  • Example: Agreement to have dinner is not a contract (no legal binding); agreement to build a house for payment IS a contract
ANSWER: Differentiate between contract and agreement [2] (2075 Bhadra)
ContractAgreement
Legally enforceableMay or may not be legally enforceable
All elements (offer, acceptance, consideration, legality, capacity) must be presentOnly requires mutual consent (offer + acceptance)
Written form requiredCan be oral or written
Legal remedies available for breachNo legal remedy if informal
All contracts are agreementsAll agreements are NOT contracts

Elements of a Valid Contract 2078 2076

  1. Offer and Acceptance: If a person advances a proposal and another makes acceptance, a contract exists. If no time limit is specified, it must be accepted within reasonable time. If the offerer dies or becomes insane before acceptance, no contract exists.
  2. Consideration: The cause, motive, price or impelling influence that induces a contracting party to enter into a contract. Something of value exchanged by contracting parties.
  3. Capacity to contract: All parties must be capable. Idiots, drunkards, insane, and children below 16 years are not capable of signing contracts.
  4. Lawful purpose: An illegal contract is invalid.
  5. Possibility of performance: An impossible contract is invalid.
  6. Free consent: The contract should not involve coercion, fraud, undue influence, or deceit.
  7. Certainty: Vague/ambiguous contracts are not valid.
  8. Legal relationship: Clear intention of parties to enter into contract with necessary documents.
  9. Written form: Verbal agreement cannot be a contract.
  10. Two or more competent parties

Contract as per Enforceability

  1. Valid Contract: If all elements of the contract are present.
  2. Voidable Contract: Contracts that a party may make void:
    • Forceful contract or contract against free consent
    • Entered due to undue influence
    • Contract involving fraud or misstatement
  3. Void Contract: Null and void:
    • Contrary to statutory law
    • Ambiguous, vague, and unlimited contract
    • Not the possibility of performance
    • Contrary to public policy and welfare
    • Signed by incompetent parties

5.2.2 Types of Contract 2079 2078 2076 2075 2074 2073 2071 2070

Contracts are classified by three characteristics:

  1. Method of payment for the work
  2. Method by which the contractor is selected
  3. Method of allocating technical and administrative responsibility
ANSWER: Name/List types of contract [Part of 6] (2079 Chaitra, 2073 Magh, 2070 Bhadra, 2075 Bhadra)

A. By Method of Payment:

  1. Lump-Sum / Stipulated Sum Contract
  2. Unit-Price / Schedule of Rates Contract
  3. Cost-Plus Contract (Cost + Percent, Cost + Fixed Fee, Cost + Fixed Fee + Profit Sharing, Cost + Sliding Fee)
  4. Percentage Contract

B. By Method of Selecting Contractor:

  1. Competitively Tendered Contract
  2. Negotiated Contract

C. By Technical & Administrative Responsibility:

  4. EPC Contract (Engineering, Procurement & Construction)
  5. Turn-Key Contract
  6. BOOT Contract (Build-Own-Operate-Transfer)
  7. Construction Management Contract
  8. BOO Contract (Build-Own-Operate)
  9. BTO Contract (Build-Transfer-Operate)

A. Classification by Method of Payment 2076 2075 2071

(a) Lump-Sum / Stipulated Sum Contracts

(b) Unit-Price / Schedule of Rates Contracts

ANSWER: Write short notes on Unit price contract and its disadvantages [3] (2077 Chaitra)

Unit Price Contract: Project is broken into measurable work items. Contractor quotes unit price for each item. Payment based on actual quantities measured in field multiplied by quoted unit rates.

Disadvantages:

  • Final cost is uncertain until all work is measured — overruns possible
  • Requires detailed measurement of every item — time-consuming
  • Disputes may arise over measurement methods and quantities
  • Contractor may "unbalance" bid by inflating rates for items likely to increase
  • Requires complete BOQ preparation before tendering

(c) Cost-Plus Contracts

i. Cost + Percent of Cost:

ii. Cost + Fixed Fee:

iii. Cost + Fixed Fee + Profit Sharing:

iv. Cost + Sliding Fee:

Fee = R (2T - A)

Where: T = Target price, R = Base percent value, A = Actual cost of construction

Advantages of Cost-Plus (Owner's Position):

Advantages of Cost-Plus (Contractor's Position):

Disadvantages of Cost-Plus (Owner's Position):

Disadvantages of Cost-Plus (Contractor's Position):

ANSWER: Classify contract based on payment. Explain lump sum contract and cost plus contract. [2+2+4] (2071 Bhadra)

Classification by Method of Payment:

  1. Lump-Sum Contract — single fixed price for entire work
  2. Unit-Price Contract — rate per measured work item
  3. Cost-Plus Contract — actual cost + fee/percentage

Lump Sum Contract:

  • Contractor quotes one single price based on complete plans and specifications
  • Covers all direct costs (staff, machines, materials) and indirect costs (overhead, maintenance) + profit
  • Risk lies with contractor — cost overruns absorbed by contractor
  • Used when scope is well-defined and design is complete

Cost Plus Contract:

  • Contractor reimbursed for all actual costs incurred + a fee for overhead and profit
  • Four types: Cost + Percent of Cost, Cost + Fixed Fee, Cost + Fixed Fee + Profit Sharing, Cost + Sliding Fee
  • Advantages: Permits fast-tracking, quick reaction to design changes, contractor expertise during design
  • Disadvantages: Owner bears cost risk, potential for abuse, increased owner involvement needed
  • Formula for sliding fee: Fee = R(2T − A) where T=target price, R=base percent, A=actual cost

B. Classification by Method of Selecting the Contractor

(a) Competitively Tendered Contracts

(b) Negotiated Contracts

C. Classification by Technical & Administrative Responsibility

(a) Traditional Approach

Works well provided:

Types under traditional: Lump-sum, Unit-price, Negotiated cost-plus fee contracts.

(b) Owner-Builder Approach

(c) Design and Build (D&B) Contract

ANSWER: Explain different types of contract based on technical and administrative responsibility [5] (2078 Chaitra)
  1. Traditional Approach: Design team prepares plans/specs before contractor selection. Design and construction separated by tendering period. Construction by single general contractor.
  2. Owner-Builder: Owner performs own design and some/all construction (force account).
  3. Design & Build (D&B): Single contractor handles both design and construction for lump-sum price.
  4. EPC (Engineering, Procurement, Construction): Contractor designs, procures materials, and builds. Carries risk for schedule and budget for fixed price.
  5. Turn-Key: Contractor entrusted to design, construct, commission, and handover. "Just turn a key in the door."
  6. BOOT (Build-Own-Operate-Transfer): Private entity finances, builds, operates facility, then transfers to government after concession period.
  7. Construction Management: Professional management firm coordinates all project activities. Owner retains control over design and contractor selection.

(d) EPC Contract (Engineering, Procurement and Construction) 2080 2079

ANSWER: Explain EPC contract in brief [2] (2080 Chaitra)
  • EPC = Engineering, Procurement, and Construction
  • Single contractor responsible for complete project delivery — design (engineering), material procurement, and construction
  • Contractor carries project risk for both schedule and budget for a fixed price
  • May subcontract parts of the work
  • Paid in agreed installments as per contract milestones

(e) Turn-Key Contract 2079 2074

Major components of BOOT:

Advantages of BOOT:

Comparison of Turn-Key and BOOT

ANSWER: Explain BOOT contract and Turn-Key contract [4+4] (2079 Shrawan)

BOOT Contract (Build-Own-Operate-Transfer):

  • Private entity receives concession from government to finance, design, construct, and operate a facility
  • Recovers investment through user fees over the concession period
  • Build: Design, procure, construct, and finance the project
  • Own: Own the asset for the concession period
  • Operate: Manage, maintain, deliver services, and receive payment
  • Transfer: Handover plant in operating condition at end of concession
  • Example: Toll roads, hydropower projects in Nepal
  • Advantages: No public budget burden, private investment promotion, timely completion, technology transfer

Turn-Key Contract:

  • Contractor entrusted to design, construct, commission, and handover the project
  • "Just turn a key in the door" — project delivered ready-to-use
  • Employer makes lump-sum payment at different stages
  • Entire risk borne by the contractor
  • Advantages: Single responsibility, rapid operation, minimal owner coordination
  • Disadvantages: No firm cost until design progresses, quality may be compromised, few checks and balances
ANSWER: What is BOOT Contract? Explain its importance in Developing Countries like Nepal [2+4] (2070 Magh)

BOOT: Build-Own-Operate-Transfer — a form of project financing where private entity receives concession to finance, design, construct, and operate a facility, then transfers it to government after concession period.

Importance in Developing Countries like Nepal:

  • Financial constraint: Government has limited budget for infrastructure — BOOT allows private sector to finance projects
  • Technology transfer: Foreign companies bring advanced construction and operational technology
  • Timely completion: Private sector incentive ensures projects completed on time without cost overruns
  • Professional management: Efficient operation and good management practices introduced
  • No public debt burden: Infrastructure development without straining government budget
  • Revenue generation: Government eventually receives operational facility without investment
  • Nepal examples: Upper Tamakoshi Hydropower, various toll road projects

(g) Construction Management Contracts 2079

Advantages:

(h) BOO Contract (Build-Own-Operate) 2079

(i) BTO Contract (Build-Transfer-Operate) 2079

ANSWER: Explain with suitable examples: EPC contract, Turn key contract, BOO contract and BTO contract [4] (2079 Jestha)
  1. EPC (Engineering, Procurement, Construction): Single contractor designs, procures materials, and builds for fixed price. Carries schedule and budget risk. Example: Power plant construction.
  2. Turn-Key: Contractor designs, constructs, commissions, and delivers ready-to-use project. Employer just "turns the key." Lump-sum payment at stages. Example: Factory construction.
  3. BOO (Build-Own-Operate): Private entity builds, owns, and operates permanently. No transfer to government. Example: Waste treatment plant operated by private company.
  4. BTO (Build-Transfer-Operate): Private entity builds, transfers ownership to government immediately, but operates under lease agreement. Example: Hospital built by private company, owned by government, operated privately.

  6. Return of Bid Security: Bid security of unsuccessful bidders returned; successful bidder's security returned after performance security submission

Performance Security

ANSWER: Explain Performance Security in brief [2] (2080 Chaitra)
  • Performance Security is a financial guarantee submitted by the successful bidder after contract award to ensure satisfactory completion of work
  • Normally 5% of bid price in cash deposit or bank guarantee
  • If BP < 0.85 × EP: PS = 5% of BP + 0.5 × (0.85×EP − BP)
  • If bids are excessively low or front-loaded: additional 8% may be demanded
  • Refunded after completion of Defect Liability Period
  • Forfeited if work is unsatisfactory or contractor defaults
If Bid Price < 0.85 × Estimated Price: PS = 5% of BP + 0.5 × (0.85×EP − BP) Normal PS: 5-13% of Contract Bid Security: 2-3% of Estimated
Fig 5.8 — Performance Security & Bid Security Formulae

Performance Guarantee Calculation Example 2081

Past Exam (2081 Shrawan): Calculate performance guarantee amount required for a contractor whose bidding amount is Rs 1,00,50,000. The estimated cost of the project is Rs 2,00,00,000. As per PPR 2064. [2]

Given: BP (Bid Price) = Rs 1,00,50,000; EP (Estimated Price) = Rs 2,00,00,000

Step 1: Check if BP ≥ 0.85 × EP

0.85 × EP = 0.85 × 2,00,00,000 = Rs 1,70,00,000

Since BP (1,00,50,000) < 0.85 × EP (1,70,00,000), the bid is >15% below estimate.

Step 2: Apply additional PS formula:

Additional PS = (0.85 × EP − BP) × 0.5 = (1,70,00,000 − 1,00,50,000) × 0.5 = 69,50,000 × 0.5 = Rs 34,75,000

Step 3: Basic PS = 5% of BP = 0.05 × 1,00,50,000 = Rs 5,02,500

Total Performance Guarantee = Rs 34,75,000 + Rs 5,02,500 = Rs 39,77,500

  6. Write short notes on: Pre-qualification of contractors. [5] (2073 Magh)
ANSWER: Explain about Pre-qualification of contractor / Why it is necessary [4/5] (2079 Shrawan, 2074 Bhadra, 2075 Bhadra, 2073 Magh, 2070 Bhadra)

Pre-Qualification: The process of evaluating and shortlisting contractors based on their capability, experience, and resources before they are invited to submit bids. It is a preliminary screening to ensure only competent firms participate in bidding.

Why Pre-Qualification is Necessary:

  1. Quality assurance: Only capable and experienced contractors compete, ensuring better quality of work
  2. Risk reduction: Reduces risk of awarding contract to unqualified firms that may default
  3. Time saving: Fewer bids to evaluate in detail, saving evaluation time
  4. Competitive pricing: Qualified firms price competitively knowing they compete against equally qualified bidders
  5. Avoid crowding: Filters out unqualified bidders, making bidding process manageable

Pre-qualification Criteria:

  1. Experience: Past performance on similar projects (size, complexity, type)
  2. Financial capacity: Bank statements, annual turnover, available credit lines
  3. Equipment: Owned or available equipment relevant to the work
  4. Personnel: Qualified key staff with relevant experience (CVs)
  5. Litigation history: Past and pending legal disputes
  6. Current commitments: Ongoing work and available capacity

Advantages: JV formation, competitive pricing, conflict identification, saves evaluation time, reduces problems from unqualified low bids.

Disadvantages: Increases procurement lead time, requires reviewing all applications, easier collusion among identified bidders, potential bias in subjective criteria.

b) Quality Based Selection (QBS)

c) Least Cost-Based Selection

d) Fixed Budget Selection (FBS)

e) Consultants' Qualifications Selection (CQS)

f) Single-Source Selection (SSS)

ANSWER: Explain methods of selection of consultants as per PPA and PPR in Nepal [6] (2081 Shrawan)
  1. QCBS (Quality and Cost Based Selection): Both technical quality and cost evaluated. Most common method. Technical weightage typically 80%, Financial 20%.
  2. QBS (Quality Based Selection): Only quality evaluated; financial proposal of top-ranked firm opened and negotiated. For complex/specialized assignments.
  3. LCS (Least Cost Selection): Among firms meeting minimum technical score, lowest cost selected. For standard/routine tasks.
  4. FBS (Fixed Budget Selection): Budget is fixed; highest-quality proposal within budget wins.
  5. CQS (Consultant Qualification Selection): Based on qualifications and experience. For small, simple assignments.
  6. SSS (Single Source Selection): Direct negotiation without competition. For emergencies, continuity, or unique expertise.

Process: EOI notice → Shortlisting → RFP to shortlisted firms → Proposal submission → Technical evaluation → Financial evaluation → Negotiation → Contract award.

Expression of Interest (EOI)

ANSWER: Write short notes on Pre-bid meeting [4] (2073 Bhadra)
  • Pre-bid meeting (also called pre-bid conference) is a meeting organized by the procuring entity for prospective bidders before bid submission deadline
  • Purpose: To clarify the bidding documents, specifications, scope of work, and answer bidders' questions
  • All questions raised and answers given are recorded in minutes
  • Minutes are circulated to all prospective bidders as an addendum to the bidding documents
  • Responses become part of the contract documents
  • Conducted for large, complex projects where tender documents may need clarification
  • Employers may relax rigid conditions based on feedback for better offers
  • Attendance is usually optional but highly recommended

Types of Contract for Consultancy Service

  1. Time-based contract: Fee = rate × time consumed. For work where period cannot be predicted (e.g., supervision of construction, complex designs).
  2. Performance-based contract: Fee based on work completed or as and when required.
  3. Lump-sum contract: For clearly identified work with low risk (feasibility study, project design, preparation of bidding documents).
  4. Percentage-based contract: Payment as percentage of estimated or actual cost of the concerned work. For inspection, architect's services, supervision, or monitoring.
  5. Indefinite service period contract: For consultancy required from time to time — arbitrators, dispute resolution, procurement consultants, technical troubleshooters.
