Project Appraisal: Technical Feasibility and Economic Viability

Project appraisal is the systematic ex-ante evaluation of a proposed project to judge whether it is technically sound, economically worthwhile, financially viable, and administratively feasible before committing scarce public resources. Under technical feasibility and economic viability, the main appraisal methods are as follows.

A. Technical Feasibility Appraisal

B. Economic Viability Appraisal

Decision rules: accept if NPV > 0, IRR > opportunity cost of capital (say 10–12%), BCR > 1, and payback within acceptable period. In Nepal, PPMO and National Planning Commission guidelines require these tests for projects above threshold size.

Making These Factors More Responsible in Implementation and Control

Nepal's chronic time and cost overruns — incomplete national pride projects, repeated cost escalation, and low capital expenditure — stem largely from weak translation of appraisal findings into implementation discipline. The following measures make technical and economic appraisal "responsible" in practice:

1. Realistic and enforceable appraisal. Base estimates on field-verified data, not desk assumptions. Fix a cost and time baseline at approval and make any revision beyond a small percentage (e.g., 10%) subject to re-appraisal by NPC/PPMO rather than routine administrative approval. This ends the practice of "approve low, revise high."

2. Binding pre-conditions before contract award. Land acquisition, utility shifting, tree felling, and right-of-way clearance must be completed or fully funded before tender. Most overruns begin here. Introduce a project readiness filter — no budget release without readiness certification.

3. Strengthened contract management. Use standard PPMO bidding documents, performance security, retention money, and liquidated damages actually enforced. Discourage unsolicited variations and price escalation clauses that transfer all risk to the government. Introduce design–build or EPC models where capacity is weak.

4. Multi-year, predictable budgeting. Link the Medium-Term Expenditure Framework to project schedules so that annual allocations match the critical path. Under-allocation forces contractors to idle, raising costs and extending time.

5. Institutional capacity and accountability. Deploy qualified engineers, project managers, and financial managers; make the Project Chief accountable for milestones with performance-based contracts. Separate the implementing and monitoring functions.

6. Independent monitoring and evaluation. Real-time MIS (e.g., NPMIS), third-party technical audits, and social audits under the Right to Information Act. Publish physical and financial progress against baseline; use earned value analysis to detect slippage early.

7. Risk management and contingency. Identify risks at appraisal (geological, monsoon, land, procurement delays), cost them, and hold a contingency reserve instead of ad-hoc escalation. Apply sensitivity analysis results as trigger points for corrective action.

8. Coordination and dispute resolution. One-stop coordination among ministries, local governments, and contractors; timely decisions on variations and disputes to avoid arbitration delays and interest burdens.

9. Incentives and sanctions. Reward projects completing within baseline; blacklist defaulting contractors and hold officials accountable for negligent appraisal or delayed decisions.

10. Political and policy stability. Shield project baselines from frequent changes of minister or government; ensure commitment continuity across fiscal years.

Conclusion. Technical feasibility and economic viability appraisal is meaningful only when its outputs — design, cost, schedule, and risk baselines — become enforceable instruments of implementation control. In Nepal, the remedy lies less in new appraisal techniques than in institutional discipline: readiness before award, realistic baselines, predictable funding, enforced contracts, and credible accountability. This converts appraisal from a formality into a genuine tool for curbing time and cost overruns.
