Direct answer
Prepare a package covering product data, throughput requirement, site and interface constraints, acceptance criteria, compliance requirements and the decision timetable.
When this decision arises
- Proposals with widely varying scope and price
- Suppliers asking the same questions repeatedly
- Long quotation lead times
- Risk premiums visible in pricing
- Scope disputes appearing after order placement
The options on the table
Product and process data
Drawings, samples, material specifications and full variability range.
Performance requirement
Throughput per variant, availability target, quality criteria.
Site and interface data
Layout, utilities, access routes, upstream/downstream equipment and protocols.
Commercial and compliance frame
Standards, documentation language, acceptance criteria, warranty and timetable.
Engineering and project considerations
- Real product samples reduce quoted risk more than any other single item
- State acceptance criteria in the enquiry so they are priced, not negotiated later
- Declare the applicable standards for the installation country
- Provide the same package to every bidder for genuine comparability
- Include your decision timetable so suppliers resource the bid properly
What to prepare before engaging engineering companies
- Product drawings, samples and specification ranges
- Volume and throughput requirement per variant
- Site layout, utilities and interface list
- Acceptance criteria, standards and documentation requirements
What to measure
Frequently asked questions
Why do suppliers quote such different prices?
Usually because they have interpreted an incomplete brief differently. A complete, identical brief compresses the spread significantly.
Should we share our budget?
Sharing a budget envelope helps suppliers propose an appropriate solution class. Sharing a precise figure tends to attract proposals priced at it.
