Before you bid on this tender
A quick checklist to help you decide whether to bid and prepare a compliant submission. Always verify the details on the official source.
- Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
- Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
- Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
- Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
- Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
- Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
