Detailed Guide to Bid Binding Standards: The Complete Process from Layout to Sealing

However good the content, non-compliant binding can still lead to rejection at preliminary review. Binding is not just "a few staples", but A complete set of standard procedures from typesetting to final sealing The key points are set out below in process order.

1. Layout Stage: Leave Enough Margin for Binding

Leave enough margin for binding (usually 2.5-3cm on the left); Consecutive page numbers, with the table of contents consistent with the page numbers in the body; for projects that require separate volumes (qualification volume, commercial volume, technical volume), name the files separately at the layout stage to avoid mixing them up.

2. Printing and stamping: the order matters

Print the body text first, then add uniformly Signatures, seals and cross-page seals; the number of originals and copies should follow the tender documents, and electronic bids require CA signing and encrypted upload.

3. Binding method: follow the requirements in the tender documents

Common methods include Adhesive binding, threadless adhesive binding, punch binding and loose-leaf binders Where the tender documents set explicit binding requirements (for example "loose-leaf binding is not permitted"), they must be followed; where there is no requirement, perfect binding is recommended for thick volumes so they do not fall apart when read.

4. Sealing and labeling: details determine success or failure

  • Label the sealed bag or box with the project name, project number and bidder name as required by the documents
  • Affix the company seal or a sealing stamp at the opening, and sign across the seam if required
  • Include an internal document list to avoid being asked at bid opening to unseal and check on the spot, only to find documents missing

5. Final check before submission

Check once more against the tender documents: "how many originals, how many copies, whether an electronic version is attached, the submission deadline and location", then set off early.
