Technical sourcing
How to compare equipment proposals beyond price
Samiyah Group ·
Compare proposals against one agreed requirement set. Record compliance, deviations, exclusions, documentation and delivery responsibilities before comparing the commercial totals.
Key takeaways
- Use one specification revision for all proposals.
- Keep a written deviation and clarification register.
- Compare the full agreed supply boundary, not isolated prices.
Create a common comparison basis
A useful comparison begins with the same operating conditions, duty requirements and scope boundaries for each proposal. If suppliers receive different information, apparent differences in price may simply reflect different assumptions.
Request evidence for material differences
Reference the relevant datasheet or proposal section. Use “not confirmed” when information is missing; do not silently mark a requirement as compliant.
A practical comparison matrix
| Review area | Question to ask | Evidence to record |
|---|---|---|
| Technical duty | Does the proposed equipment match the stated conditions? | Datasheet and stated operating basis |
| Scope | Which accessories and interfaces are included? | Supply list and exclusions |
| Documentation | What drawings and manuals will be provided? | Document schedule |
| Delivery | Which milestones depend on approval? | Agreed schedule and dependencies |
| Site support | Who installs, tests and hands over the equipment? | Responsibility matrix |
Clarification checklist
- Confirm that every supplier used the same specification revision.
- Separate technical deviations from unanswered questions.
- Record exclusions and client-supplied items.
- Identify document review and approval milestones.
- Close critical clarifications before final selection.
Frequently asked questions
Is the lowest equipment price the lowest project cost?
Not necessarily. Differences in the supply boundary, installation requirements and support can affect the comparison. Include the costs that are relevant to the agreed scope and keep estimates visible.
What if a supplier offers an alternative?
Record the alternative separately and ask for the technical basis. The responsible project team should review its effect on interfaces and operating requirements before acceptance.
Who approves a technical deviation?
The appointed party with responsibility for the affected requirement. Define that authority at the start rather than assuming the supplier or coordinator can approve it.
