What a feasibility report looks like.
An illustrative example for a fictional company, so you can see the structure, the evidence and the way we state a recommendation.
Sample only. Example Contractors Ltd is a fictional company. All figures are illustrative and are not real project data or real client results.
Feasibility Proof Report
- Client
- Example Contractors Ltd (fictional mid-size MEP contractor)
- Project
- Cooling plant replacement, 12,000 m² office building
- Decision needed
- Which cooling system should we propose and install?
1 Summary of recommendation
Option C (water-cooled chillers with cooling towers) has the lowest 10-year cost, but only if the roof structure check passes and water supply is secure. If either fails, Option A is the safer choice.
2 Options compared
Illustrative 10-year view (undiscounted, USD thousands).
| Option | Capital | Energy / yr | Maintenance / yr | 10-year total | Main risk |
|---|---|---|---|---|---|
| A. Air-cooled chillers | 620 | 118 | 22 | 2,020 | Higher running cost |
| B. VRF system | 540 | 135 | 30 | 2,190 | Refrigerant volume, long pipe runs |
| C. Water-cooled chillers + towers | 780 | 86 | 34 | 1,980 | Roof loading, water use, upkeep |
Option C costs about 160 more upfront than Option A but saves about 32 a year in energy. The 10-year gap is small, so the conditions below matter more than the headline number.
3. Conditions to confirm first
- Structural check of the roof for tower loads
- Confirmed water supply and treatment plan
- Plant room access for chiller replacement
4. Risks and how to reduce them
- Cost overrun: fixed-price supplier quotes before tender
- Programme delay: order long-lead chillers early
- Maintenance burden: agree a service contract up front
5. Assumptions and limits
- Prices and energy figures are placeholders
- No discounting or inflation applied
- Final design is outside this study
