Existing Atlantic photograph of an ice well and scoop for collection context. It is not the fictional venue, source records or portion observations and demonstrates no measured demand, approved storage level or handling procedure.
The bar forecast says 14.4 kg. The event requisition says 12 kg. Adding them produces a convincing 26.4 kg request—until someone notices that the event sheet includes 4 kg already allocated to the bar.
Send the ice supplier a demand brief with traceable sources, one counting boundary and each quantity labelled as measured or forecast. The completed example below removes the duplicate without pretending that the corrected total sizes a machine. It also shows what the buyer still needs to establish before asking for a model recommendation.
Decide what crosses the boundary you are counting
Define the location and service period before gathering totals. Are you counting ice issued from a central store, ice placed in a bar well, or ice finally used in drinks? The same ice can appear in all three records. Those records describe different stages of its movement, not three independent demands.
Keep the actual ice form and menu/task definitions with the record. “Drinks”, “customers”, “scoops” and kilograms are not interchangeable units. A sales-item count becomes an ice estimate only after the relevant items and portion assumptions are identified. A container count needs its actual measured quantity, not its advertised volume.
Record the source identity, version and period beside each number. Include the person responsible for explaining whether an event requisition is additional to the bar forecast or includes part of it. An unexplained total is a question to resolve, not a reliable sizing input.
Read the sources before adding the numbers
All documents, observations, quantities and responses in this example are fictional. No real venue was measured. The buyer is preparing a source pack for ice issued from the venue's central supply during 18:00–19:00. Both bar setup and the separate function transfer fall within that defined period.
Forecast B2 contains 80 specified iced-drink items for that hour. It is not 80 customers, 80 transactions or a measured withdrawal. Portion record M1 contains three example observations for that same drink/ice specification: 170 g, 180 g and 190 g. Their arithmetic mean is (170 + 180 + 190) ÷ 3 = 180 g, or 0.18 kg.
Applying that example mean to B2 gives 80 × 0.18 = 14.4 kg for the bar task. That is a forecast extrapolation from three fictional observations, not evidence that every drink uses 180 g or that the venue has withdrawn 14.4 kg. A real brief needs a representative portion basis and the menu mix actually forecast.
| Source | What it actually says | Evidence type | How the buyer uses it |
|---|---|---|---|
| B2 bar forecast | 80 specified iced-drink items during 18:00–19:00 | Forecast count | Apply the stated portion basis; do not label as measured ice demand |
| M1 portion record | 170 g, 180 g and 190 g for the defined example drink/ice task | Fictional sample observations | 180 g arithmetic mean; representativeness remains a real-world question |
| F2 current event requisition | 12 kg requested for issue during the same hour: 4 kg bar setup plus 8 kg separate function transfer | Requested allocation, not an actual issue record | Bar setup is included in the bar forecast requirement, not additional to it |
| F1 earlier requisition | Superseded by F2 | Historical source | Retain as history; exclude from the active calculation |
Scroll the table sideways to see every column.
The event organiser's completed fictional response confirms the important relationship: F2's 4 kg bar setup is part of the ice intended to satisfy B2's drinks. The 8 kg function transfer is separate. The buyer now has a reason to remove one duplicate, rather than simply choose the smaller total.
Correct the brief while keeping the assumptions visible
The first brief added the 14.4 kg bar estimate to all 12 kg on F2. That counted the bar's setup allocation a second time. The corrected brief retains the 14.4 kg bar requirement and adds only F2's separate 8 kg function transfer.
| Brief line | Initial calculation | Corrected calculation | Reason |
|---|---|---|---|
| Bar task | 14.4 kg | 14.4 kg | Same 80-item forecast and stated 0.18 kg portion basis |
| Event requisition added | 12 kg | 8 kg | F2's 4 kg bar setup already belongs to the bar requirement |
| Combined stated requirement | 26.4 kg | 22.4 kg | Remove the identified 4 kg duplicate, not the separate function task |
Scroll the table sideways to see every column.
Replace the 26.4 kg brief with 22.4 kg on this stated basis, and attach B2/M1/F2 plus the inclusion response. Mark F1 superseded. The supplier can now see which menu forecast, portion assumption and event allocation generated the request.
The correction does not reduce the number of forecast drinks or cancel part of the function. Nor does it prove that 22.4 kg is the venue's complete actual requirement. The simplified estimate omits losses and other withdrawals, and the three-sample portion basis may not represent the actual product mix. Keep those limitations beside the total.
Do not turn the 4 kg setup allocation into a prescribed fill level or safe holding allowance. It explains a document overlap. The venue's actual product, handling and food-safety arrangements remain for its responsible people to establish.
Turn the corrected pack into a model-ready enquiry
The next task is to establish when the ice is required, what usable opening stock exists and what replenishment can actually reach the service route. An hour's total does not show whether the function takes its whole allocation at the start or later. Get those event times and order from the relevant departments rather than inventing an even withdrawal rate.
Use the reserve-and-replenishment comparison for that event test and the commercial ice-machine guide for the wider system choice. This source pack corrects the input evidence; it does not repeat their stock or production calculations.
Keep the selected model's rating conditions separate from the demand estimate. For example, Hoshizaki Australia's IM-240ANE-28 page publishes production figures against different air and incoming-water conditions. That is a reason to request the applicable conditions and supported response for your actual system, not to treat a daily rating as ice arriving evenly throughout this hour.
Send the actual site information, intended ice form, source pack and remaining timing questions together. Ask the supplier to identify what further evidence is needed and which assumptions its proposal depends on. If the menu, portion basis or event requisition changes, update the calculation and brief version before comparing another offer.
Our illustrative 18:00–19:00 central-issue brief uses B2's 80 drink items and M1's 0.18 kg example mean to forecast 14.4 kg for the bar. F2 includes 4 kg of that bar setup plus a separate 8 kg function transfer. We have removed the duplicate and record 22.4 kg on this stated basis, with sample, loss and timing limitations visible.
For our real proposal, please use the attached current sources and task definitions. Identify the opening-stock, withdrawal timing, replenishment, rating-condition and site evidence required before recommending a complete system. Do not treat a forecast calculation as an actual machine trial.
Replace the fictional records with your current evidence and send the ice-demand source pack to Atlantic Equipment. The useful result is a question the supplier can trace and challenge, rather than a confident total assembled from overlapping documents.
About this guide
Prepared by Atlantic Equipment to help commercial buyers prepare traceable ice-demand evidence before model selection. B2/M1/F1/F2, the portion observations and inclusion response are fictional. The example separates sample observations, forecast extrapolation and requested allocations; its corrected total is not a machine size or measured venue demand. The Hoshizaki rating-condition reference was read on 18 October 2026. No operating, handling or food-process instructions are provided.
