Tender documentation for construction projects
A tender is a submission made by a prospective supplier in response to an invitation to tender. It makes an offer for the supply of goods or services. Tender documents are prepared to seek tenders (offers).
Ideally, tender documents should be broken down into a series of packages (even if there will only be one main contract) each with its own design drawings and specifications suitable to be issued by the main contractor to potential sub-contractors. This makes the tender easier for the contractor to price and easier for the client to compare with other tenderers.
It is important, when this is done, to ensure that the interfaces between packages are properly identified and clearly allocated to one package or another. Having too many packages increases the number of interfaces and so the potential problems. The cost plan (pre-tender estimate) should also be re-assembled package by package to allow easy appraisal of tenders received.

- A letter of invitation to tender.
- The form of tender.
- Preliminaries: including pre-construction information and site waste management plan (if required).
- The form of contract, contract conditions and amendments. This might include a model enabling amendment for building information modelling (BIM), making a BIM protocol a contractual document.
- A tender pricing document (or contract sum analysis on design and build projects).
- Employer's information requirements for BIM.
- Design drawings, and perhaps an existing building information model.
- Tender return slip.
Copies of the tender documentation should be kept for records.
