Techno-economic services

1. Bankable feasibility studies

Market, technical and financial sections are prepared by specialists and the project's economic indicators are then estimated and analysed in COMFAR III (capital and operating costs, financial and economic analysis, sensitivity analysis and risk management).

  • Market studies:
    • Product(s) and project introduction
    • Raw materials and supply
    • Domestic and global price review
    • Implementation considerations and the industry's place in national economic policy
    • Supply-and-demand analysis and forecasting, shortages or surpluses
    • Domestic, global and export target markets
  • Technical studies:
    • Review of production processes and selection of the best process
    • Technology licensors and know-how pricing
    • Technology sustainability and economic life of the process
    • Production capacity, operating time and product specifications
    • Raw material and utility specifications and consumption
    • Process and utility descriptions with Block & Process Flow Diagrams
    • Main equipment list and domestic and foreign manufacturers
    • Manpower and organization chart
    • Safety, environmental and industrial effluent considerations
    • Land and building area estimation and site selection
  • Financial & economic studies:
    • Fixed investment, working capital and annual production costs
    • Depreciation, annual sales and unit cost
    • Sources of finance and funding schedule
    • Profit and loss for total investment and for equity
    • Loan interest and repayment schedules
    • Net cash flow, IRR, payback period and NPV
  • Break-even analysis
  • Value added, productivity and foreign-exchange savings
  • Sensitivity analysis

2. Monitoring of bank-financed projects

Based on the approved plan, the activity schedule and fund usage are defined; the site is visited at set intervals and, after reviewing financial and technical records, progress and compliance with the approved plan are reported (using Primavera) along with corrective recommendations.

  • Initial project planning:
    • Project WBS
    • Resource allocation based on investment costs
    • Initial cost and progress report
    • Two-month forecast
  • Periodic control reports:
    • Site visits and physical progress measurement
    • Planned vs. actual progress comparison
    • Actualization of activity time and cost and schedule updates

3. Business plans

Most investors commit only when they fully understand the business and its finances. We prepare business plans on request, covering:

  • Format, structure and executive summary
  • Vision, mission and objectives
  • SWOT analysis
  • Organizational and marketing plans
  • Financial plan and risk-management assessment
