| Scenario | Layout | Length / Size | Min spacing | Max spacing | Result barricades |
|---|---|---|---|---|---|
| Sidewalk closure | Linear | 30 m | 1.0 m | 3.0 m | 11 |
| Material laydown | Rectangle | 12 m × 8 m | 1.5 m | 3.0 m | 14 |
| Open excavation | Circle | Diameter 10 m | 1.0 m | 2.0 m | 16 |
Barricades work best when they form a continuous visual boundary. Uneven gaps create “invitation points” where pedestrians or equipment can drift into a hazard zone. A spacing plan also simplifies daily setup because crews can repeat a measured pattern rather than deciding placement by feel.
This calculator uses total protected length, optional end offsets, and your minimum and maximum spacing limits. End offsets are useful when you must keep entrances clear or avoid obstructions. Spacing limits represent the tightest and loosest spacing your plan allows.
Linear runs place barricades at both ends, plus evenly spaced units between. Loop layouts distribute barricades around a closed perimeter so the last segment meets the first. Rectangle mode converts length and width into perimeter, while circle mode converts diameter into circumference.
Auto mode selects a practical interval count so the computed spacing stays at or below your maximum limit. Example: if an effective length is 29 m and maximum spacing is 3 m, the calculator chooses N = ceil(29/3) = 10 intervals, producing 2.9 m spacing and 11 barricades on a line.
When barricade panels, cones, or fence sections are laid out on known centers, target spacing is helpful. The calculator rounds to a realistic interval count and reports the actual spacing, so you can confirm it still fits your allowable range before committing to a layout.
Positions are distances from a defined reference. For linear runs, the first position includes the end offset. For loops, the first position starts at zero around the perimeter. If your start point is a corner or gate, align it to a fixed mark so the list remains repeatable.
Real sites rarely match perfect geometry. Tighten spacing near corners, walkways, or equipment crossings. If the calculator’s spacing is acceptable but a specific spot needs reinforcement, shift one or two units locally while keeping the overall count and average spacing close to the plan.
Exporting results supports consistent implementation. Use the CSV for a complete position list and the PDF for quick briefings. Record the spacing limits used, the final count, and any field deviations. Clear documentation helps inspections, turnover between shifts, and future rework.
It is the length that actually gets evenly divided. For a line, effective length subtracts two end offsets. For rectangle and circle layouts, it equals the perimeter or circumference used for spacing.
Auto mode uses the maximum spacing limit to choose an interval count. Small length changes can push the ceiling calculation to the next interval, which increases barricade count but keeps spacing within the limit.
Use both as guardrails. The minimum prevents overcrowding where it creates conflicts, and the maximum prevents unsafe gaps. If the two limits cannot both be met, tighten the maximum or relax the minimum based on site needs.
Choose an offset that keeps entrances clear, avoids drains and obstructions, and still leaves enough effective length to distribute barricades. If offsets consume too much length, reduce them or reconsider the run reference points.
A closed loop connects back to its start, so each barricade begins a segment and the final segment returns to the first barricade. That makes the number of segments equal to the number of barricades.
Yes, for minor field constraints. Keep the overall count and average spacing close to the computed value, tighten spacing near hazards, and document any shifts. Recalculate if the protected length or layout shape changes materially.
Use the PDF for quick setup guidance and the CSV when you need exact position marks. Pair the export with a clear start reference, such as a corner, gate post, or painted station point.
Keep spacing tighter near pedestrian crossings, equipment entrances, and transitions. Ensure clear, continuous guidance along the protected edge.
Corners often need additional coverage. Where vehicles or pedestrians approach at angles, consider adding a barricade closer than the general spacing.
Adjust placements to avoid trip hazards, drains, or steep slopes. Maintain a continuous visual line even if positions are shifted slightly on site.
High winds may require reduced spacing and added ballast. Review manufacturer guidance and your site plan for stability requirements.
If lighting is limited, choose closer spacing and add reflective elements. Confirm visibility from expected approach paths.
Record the spacing limits, computed quantities, and deviations. Keep the exported file available for daily briefings and inspections.
When the work zone expands or shrinks, recalculate. Small geometry changes can shift the interval count and produce different spacing.
Auto mode picks a conservative interval count. If you must match existing panel centers, use target spacing and confirm the actual spacing remains acceptable.
Build safer sites with consistent barricade spacing every day.
