01
What belongs in each bid cover?
Upload qualification evidence, technical response, methodology and non-price schedules in the technical cover. Upload rates and totals only through the prescribed financial form or BOQ. If the tender uses additional covers for fee, prequalification or quality submissions, follow that structure exactly.
Practical checks
- Use a cover-by-cover submission checklist.
- Remove rates from technical schedules and filenames.
- Do not upload the BOQ to the wrong cover.

- Answer every mandatory specification.
- Keep assumptions out of the price schedule unless permitted.

Building a sustainable tender price

Practical checks
- Document supplier quotations and assumptions.
- Stress-test cash flow and payment delays.
- Do not chase L1 below executable cost.
