Without detailed basic engineering or detailed engineering, it is not possible to quote for a project.
The actual capacity of the system (Tm/hr, m3/hr, kW, etc.) is not clearly defined.
There is a risk of oversizing (higher CAPEX and OPEX) or undersizing (operational failures).

The other problem is that without the engineering, it is not possible to obtain the building permit and the factory cannot begin to be built.
1. Architectural plan.
2. Technical file for the civil works (topography, earthworks, foundations, reinforced concrete slabs, drains).
3. Metal structures file.
4. Electrical file (medium voltage and low voltage).
5. Industrial refrigeration file.
6. Fire protection system file.
7. Layout of all machinery and warehouse design. All technological advances must be analysed.
8. Water supply system for the entire plant.
9. Pneumatic supply system for the plant.
10………………………………..

For example: The design adequately defines whether the refrigeration system will be:
1. Direct expansion.
2. Flooded.
3. Recirculated/pumped
4. Single or double stage (key for temperatures < –20 °C)

Engineering determines which system is needed, not the supplier.
Engineering defines the best refrigerant to use, for example: ammonia, CO2, etc., based on need, electricity consumption and COP.

With the project completed, you can ensure that all bids are comparable.

If you tender without engineering:

*Each supplier designs ‘their own way’.
*The proposals are not comparable (apples and oranges 🍎🍐).
*The cheapest wins… not necessarily the most suitable.

If you tender with basic and detailed engineering:
*Everyone quotes on the same technical scope.
* You can compare: Equipment, Efficiency, Energy consumption, Safety level, Regulatory compliance.
* You tender on price and quality, not improvisation.
* Engineering pays for itself by avoiding mistakes.
