Why precise specifications matter
Vague specifications produce bids that cannot be compared. Over-restrictive ones exclude good manufacturers. Good specifications set the required performance and let manufacturers propose their solution.
The points to specify
| Section | Concrete plant | Asphalt plant |
|---|---|---|
| Capacity | Actual m³/h, concrete class | t/h at a stated aggregate moisture |
| Type | Stationary, mobile, containerised | Batch, continuous, mobile |
| Key components | Mixer, silos, bins, dosers | Dryer, burner, mixer, bitumen storage |
| Environment | Dust filters, water recycling | Baghouse, emissions |
| Controls | Mix management, delivery tickets | Mix management, traceability |
| Site conditions | Temperature, altitude, power | Temperature, altitude, fuel |
What to request besides the equipment
- Shipping and delivery to site
- Civil works drawings
- Erection and commissioning
- Operator training
- Spare parts package
- Warranty and documentation in French or English
Recommended evaluation criteria
- Point-by-point technical compliance, before price.
- Operating cost: energy, wear, labour.
- Delivery and commissioning time.
- Availability of parts and service in the region.
Frequently asked questions
Should a brand be specified?
It is better to specify performance and let manufacturers propose, unless the fleet must stay uniform.
How to compare stated capacities?
Ask for capacity under defined conditions: aggregate moisture for asphalt, concrete class and cycle time for concrete.
