Calculations happen locally in your browser. ToolLott does not send these inputs to a server for this tool.
Preliminary planning or arithmetic calculation only. Confirm project inputs, units, operating assumptions and applicable requirements before procurement, construction or operational decisions.
How to use it
Replace the worked-example values with actual project data. Review the intermediate quantities and visible assumptions before using the result elsewhere.
How the Camp Population Calculator works
Estimate average and peak on-site population from total workforce, roster cycle and overlap, then show a separate bed reserve. The methodology below exposes the production equation, a QA-verified worked example and the boundary between this screen and detailed design.
Calculation breakdown
ToolLott will explain the current inputs and displayed result here.
Roster-based camp occupancy screen
The production engine evaluates average on-site = workforce x on_days/(on_days+off_days); peak = ceil(average x (1+overlap)). It begins by calculate average rostered on-site population from workforce and roster cycle., then apply the entered peak-overlap allowance and round to whole people., and finally apply bed reserve separately for planning beds. This keeps the calculation auditable instead of hiding design assumptions behind a single number.
average on-site = workforce x on_days/(on_days+off_days); peak = ceil(average x (1+overlap))ToolLott evaluates the relationship using the entered units and full numeric precision before display rounding.
| Symbol / input | Meaning | Unit |
|---|---|---|
workforce | Total roster workforce | user input |
onDays | Roster days on | user input |
offDays | Roster days off | user input |
overlap | Peak overlap / visitor allowance (%) | user input |
bedReserve | Additional bed reserve (%) | user input |
Step-by-step method
- Calculate average rostered on-site population from workforce and roster cycle.
- Apply the entered peak-overlap allowance and round to whole people.
- Apply bed reserve separately for planning beds.
Worked example
Leo, a project engineer, is planning accommodation for 240 workers on a 14-days-on/7-days-off roster with 15% peak overlap/visitor allowance.
Example inputs
- Total roster workforce: 240
- Roster days on: 14
- Roster days off: 7
- Peak overlap / visitor allowance (%): 15
- Additional bed reserve (%): 5
Calculation / processing
Average on site = 240 x 14/(14+7) = 160 people.Peak = ceil(160 x 1.15) = 184 people.Beds = ceil(184 x 1.05) = 194.
Use the result as a screening or quantity-planning value and compare it with the project criteria, manufacturer data and applicable engineering requirements before making a design or procurement decision.
Assumptions
- The entered values are representative of the condition being screened and use the units shown on the page.
- The equation models only the stated relationship; omitted system effects are not silently estimated.
Limitations
- This page is not engineering certification and does not replace applicable standards, design loads, manufacturer data, site investigation or competent professional review.
- Results can change materially when real geometry, losses, transients, material properties, duty cycles, safety factors or regulatory criteria differ from the simplified inputs.
Common questions
Is this a final engineering design?
No. It is a transparent screening calculation using the entered assumptions and the stated equation.
Why does the page show assumptions and limitations?
Engineering formulas are only valid within their modelling assumptions; exposing them helps users decide what additional design checks are required.
Should I use the rounded displayed value in later design work?
Use suitable calculation precision and the governing project/standard requirements rather than relying on display rounding alone.
Methodology sources
This page uses basic mathematical or ToolLott implementation logic that does not require an external factual source. The worked result is still tied to the production tool and QA example.

A realistic way Leo could use this tool
Leo is a project engineer.
Leo is planning accommodation for 240 workers on a 14-days-on/7-days-off roster with 15% peak overlap/visitor allowance.
In the example, Leo uses workforce = 240; on days = 14; off days = 7; overlap = 15; bed reserve = 5. The observable result is Peak camp population: 184 people; the worked case therefore connects the source data directly to the number, text or setting shown on the page.
What changes for Leo is now explicit: Peak camp population: 184 people. The result can be checked against the real source data before they estimate average and peak on-site population from total workforce, roster cycle and overlap, then show a separate bed reserve. The page also keeps this limitation explicit: Preliminary screening/planning calculation only.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
