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).

Options compared
OptionCapitalEnergy / yrMaintenance / yr10-year totalMain risk
A. Air-cooled chillers620118222,020Higher running cost
B. VRF system540135302,190Refrigerant volume, long pipe runs
C. Water-cooled chillers + towers78086341,980Roof 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
