The specification is the document in which an awarding body describes the service it wants to procure. It is the substantive core of the tender documents and the basis on which a supplier costs and builds its bid. Depending on contract type and awarding body it is also called the scope of work, the bill of quantities, or the statement of requirements.
What belongs to the document set
The specification rarely stands alone. A complete set typically includes the tender conditions with the formal requirements, the specification or bill of quantities with the description of the service, the suitability and award criteria with their weighting, forms for submission, and the draft contract. The decisive information is spread across those documents, and contradictions between them occur. Reading only the specification routinely means missing requirements that sit in the draft contract or the conditions.
Functional and detailed descriptions
A service can be described in two ways, and the difference shapes all the bid work. A detailed description fixes exactly what is to be done and how — typical for construction with a bill of quantities running to hundreds of items. A functional description states the objective to be achieved and leaves the route to the supplier, common in IT projects and complex services. With a detailed description the effort sits in costing; with a functional one, in the solution concept — and the award criteria are weighted accordingly.
Where the variation risks sit
For a contract’s margin, the clearly described items matter less than the unclear ones. Items with open quantities, blurred boundaries between trades, missing execution detail or undefined interfaces to other parties are where variations later arise — or where margin is quietly lost. Finding those points before costing is one of the most valuable steps in the whole procedure, and it requires working through the documents early and systematically.
The question round as an instrument
Ambiguities in the specification can be clarified in the question-and-answer phase. Answers go to all suppliers, in line with the principle of equal treatment, which means a good question also helps competitors. The question round is nevertheless almost always the right choice: a clarified item is costed correctly, an unclarified one is carried as risk. The precondition is asking in time — that deadline sits well before the bid deadline and is routinely missed.
Volume as the actual problem
On larger projects, tender documents run to several hundred pages. For a company without a bid team that is the real barrier to entry — not professional suitability but the capacity to take in that volume carefully in the time available. The answer is not reading faster but extracting in a structured way: pulling out requirements, deadlines, evidence duties and knock-out criteria deliberately and recording them with a source reference, so the review stays traceable.
The practical order of work
A fixed sequence works well. First read the formal conditions and the scoring matrix to know the frame. Then hold the suitability criteria against your own body of evidence. Then work through the specification for knock-out criteria and variation risks. Only last, cost and write. That order ensures effort flows only into procedures that are actually winnable — and that the questions in the question round are the right ones.
