Create a dimension and quantity schedule
For penetrations, list diameter, quantity and location. For openings, list width and height. For cut layouts, show lengths and intended depths where known. Use millimetres for detailed opening dimensions and label any different unit explicitly.
Reference each item to the drawing
Tie each schedule entry to a marked location or drawing reference. Explain repeated items and distinguish changes between revisions. A simple labelled sketch can clarify the request while the project’s formal design information is being assembled.
Label measured values, estimates and unknowns
State whether thicknesses, quantities and dimensions are measured, taken from a drawing or estimated. Do not fill a gap with a value that looks confirmed. The office can discuss what additional information or investigation is required for the review.
Add access, handling and programme details
Quantities help explain scope, but they do not determine price on their own. Access, method, staging, support, handling and mobilisation may also matter. Add those conditions rather than relying on a length or hole count as a complete quote request.
Your enquiry checklist
- Dimensions with explicit units
- Quantities tied to marked locations
- Drawing revision and source of measurements
- Unknowns and access conditions
Send what you know and identify details still being confirmed. These guides help describe a project; the agreed site-specific scope determines the work.
