Access, existing operations, the information available and the way packages fit together all affect what needs pricing and recording. These checks help you identify where your project needs closer attention. Access and continued use Work in an occupied building or operating facility may need phased access, protection and repeated setup. Check the working hours and areas assumed in the price. Record actual access and interruptions during delivery so their effect can be assessed. Existing conditions and incomplete information Hidden services, retained structures and developing designs can change the work required. Identify which surveys and drawing revisions the price relies on, what remains an allowance and who will resolve each uncertainty. Record what is found before the work covers it up. The boundaries between packages Supply, installation, connections and testing may sit with different firms. Check who provides each part, who needs to finish first and who makes good afterwards. An item omitted by both packages can become an extra cost; an item included twice can distort the budget. Testing and handover Finishing the installation may leave testing, demonstrations and handover records outstanding. Check what the agreed completion requirements include, whose attendance is needed and how these activities are priced and programmed. Keep progress records against those requirements. ## Explore our sectors Explore the construction types and commercial considerations within each sector.

Each part brings different constraints. Use the relevant sector pages together, then identify where one package depends on another. For each significant constraint, keep a short record of the pricing assumption, responsible party, decision date and supporting information. If the assumption changes, record the event and its effect on the work. The contract and project records then provide the basis for assessing the commercial position.
