What Are Tender Documents in Construction?
Tender documents are the set of documents the employer issues to bidders so they can prepare and submit a priced offer for a project. They describe the works, the contract terms and how bids are submitted and judged, and the successful tender usually becomes part of the contract.
What a tender package usually contains
The exact list depends on the project and the contract form, but a package typically includes:
- Instructions to bidders and the tender timetable.
- Form of tender and any required forms or schedules.
- Conditions of contract, including particular conditions.
- Drawings and specifications.
- Bill of Quantities or pricing schedule.
- Addenda issued during the tender period.
How bidders review the documents
Bidders read the conditions for risk, payment terms, time and security requirements, check the drawings and specifications against the BOQ, and list clarifications and assumptions. Questions are usually sent in writing before a stated deadline, and the answers go to all bidders, often as an addendum.
From tender to contract
After submission the employer evaluates the bids on price and on technical and commercial criteria, may hold clarification meetings, and awards the contract. The final contract documents should reflect all addenda and agreed clarifications, so that what was priced is what is built.
Tenders on Gulf projects
Gulf tenders often use FIDIC-style conditions with particular conditions, and require tender security and a defined validity period. Public and private employers have their own procurement rules, so follow the tender instructions, including submission format and deadlines, exactly.
How Arkan connects to the tender stage
Arkan is used after award to manage delivery, and the priced BOQ is the main link to the tender.
- The BOQ module holds items, quantities, unit rates and amounts with cost types.
- Variations against the BOQ are recorded and carry into payment requests.
- Contract documents can be kept as controlled documents with version tracking.
Frequently asked questions

A tender is a formal priced offer against a defined package of documents, usually under set rules. A quotation is generally a simpler price for a smaller, less formal scope.
What is an addendum in a tender?
It is a formal change or clarification issued to all bidders during the tender period, which becomes part of the tender documents.
Do tender documents become part of the contract?
Often yes, in part. The contract agreement lists which documents form the contract and their order of priority.
