Production information is incorporated into tender documentation following with the contract documents and drawings.

Production information may include:

• Drawings (location drawings, component drawings and dimensioned diagrams).
• Specifications, design criteria and calculations (specification information can be included on drawings or in a separate specification, but information should not be duplicated as this can become contradictory and may cause confusion).
• Bills of quantities or schedules of work (schedules of work are ‘without quantities’ instructional specifications often produced by designers on smaller projects for pricing, or for items such as builders work and fixing schedules such as sanitary fittings, doors, windows, ironmongery, light fittings, louvers, roller shutters, diffusers, grilles and manholes).
