A single perimeter total hides where the number came from. A segment record shows the start and end markers, whether the value was measured or estimated, which opening belongs to the line, and which revision supplied the total.
1. Lock the map revision and unit
Begin with the current site-survey route. Use one declared unit within a schedule, or show every conversion explicitly. Do not combine feet, metres, map estimates and field measurements in one unlabelled total.
2. Start a segment where the route changes
Create a new segment at each start, end, corner, gate or route change. Also split the record when the measurement source or status changes. Section IDs should match the map, photographs, gate schedule and later inspection record.
| Segment | From / to marker | Role | Source | Status | Gross length | Opening | Net fence line | Evidence / note |

| ____ | ____ / ____ | Perimeter / divider | ____ | Confirmed / estimated / inaccessible | ____ | ____ | ____ | ____ |

3. Keep status separate from the number
Confirmed
- Route markers and unit are identified
- Source and date are recorded
- Gate or other opening is assigned to the same segment
- Evidence or checker is available
Provisional
- Estimated from a plan, aerial image or incomplete walk
- Route or boundary remains unresolved
- Section was inaccessible
- Measurement basis or opening is still unknown
Preserve provisional values for planning, but do not let them silently become confirmed purchase quantities. Give each open item an owner and a due date.
4. Record openings without losing their assemblies
Subtract an opening from a segment only when it replaces fence fabric or conductor on that same line. Keep the gate, gate posts, braces, hardware and any electrical crossing in the gate schedule and materials checklist.
5. Close the schedule before calculating rolls
- Every map segment has one schedule row and every schedule row appears on the map.
- Units and any conversions are shown.
- Confirmed, estimated and inaccessible lengths have separate totals.
- Each opening is assigned once and connected to the gate schedule.
- Changes in route or drawing revision trigger a new measurement revision.
- The checker signs the revision used for the roll calculation.
Questions field teams ask
Should I measure the whole perimeter as one number?
No. Keep a total, but build it from identified segments so corners, gates, route changes and provisional sections remain traceable.
Do gate openings count in fence length?
Record the gross segment and the opening separately. Deduct the opening only if it replaces fence material on that segment, while retaining the gate assembly in its own schedule.
Can I use a map or satellite estimate?
It can be recorded as a provisional planning source. Label the method, date and status, then confirm the route through the project’s approved field or survey process before purchase or construction.
How do I measure a fence on a slope?
Record the basis required by the selected system, supplier or designer and use it consistently. This worksheet does not choose between horizontal, surface or installed-line measurement.
How much extra fence should I add?
Do not hide an allowance inside the measured length. Preserve the confirmed net line, then state any planning allowance separately in the project planner with its reason and owner.
Evidence and limits
University of Maine Extension places mapping, gates and lanes before measuring fence length and preparing the material list. USDA NRCS Ohio Fence 382 also calls for a plan view showing layout and gates plus material quantities. These sources support traceable planning records; they do not establish legal boundaries, a universal measurement method or a project-specific allowance.
Map the route, plan gates and lanes, measure the length, identify load points and prepare the material list.
