What does the building site fence estimator calculate?

It rounds each entered continuous run up to a whole number of panels using the usable cover width you enter. It can add a 5% panel spare allowance. It does not calculate feet, clamps, gates, braces, ballast, wind resistance, freight, or legal compliance.

Why should I enter separate fence runs?

Each run is rounded up independently because leftover length from one run may not cover another. Enter comma-separated or line-separated lengths in metres, and leave gate openings out of those lengths.

How do I choose a panel width?

Use the supplier’s usable cover width after accounting for overlaps or connection details. Do not assume the panel frame’s outside dimension equals its installed coverage.

Does this tool calculate wind bracing or concrete ballast?

No. Wind stability depends on the actual site, panel system, ground, connections, screening, and applicable design method. Ask the supplier or a competent designer for documented requirements for the exact configuration.

What changes when privacy mesh, debris netting, or signs are added?

Added surface area can change wind actions and support requirements. WorkSafe Victoria specifically warns that screens and signage may require added support. Recheck the design before attaching them.

Does AS 4687 set one panel size or ballast amount for every site?

The public catalogue descriptions for AS 4687.1 and AS 4687.2 describe design, analysis, testing, installation, and performance requirements. They do not establish a universal panel size or ballast number in the summaries. Consult the current full standard and the site-specific design.

Does OSHA 1926.502 certify a construction-site boundary fence?

No. OSHA identifies 1926.502 as fall-protection system criteria. Requirements for public protection, property boundaries, and site security also depend on state and local rules and the project conditions.

What should I check for gates and emergency exits?

Plan access and emergency escape with the site safety lead and the authority having jurisdiction. OSHA 1926.34 addresses unobstructed egress from occupied buildings or structures; do not assume that it specifies hardware or dimensions for every exterior fence gate.

Should I check for underground services before using ground anchors?

Yes. Check service records and use the local utility-location and notification process before ground-penetrating work. OSHA 1926.651(b) covers utility location and owner contact before excavation work; one-call requirements and timelines vary by jurisdiction.

Is there a universal 100 mm maximum gap under a temporary fence?

This page does not state a universal clearance limit. HSE guidance says to keep gaps as small as possible to prevent access; project rules and the applicable standard may set more specific requirements.

How do I compare renting with buying?

Compare actual quotes over the planned project duration. Include delivery, setup, maintenance, damage or loss terms, demobilization, storage, resale value, and future reuse. The break-even point depends on those inputs, so this page does not publish a universal month or saving percentage.

What documentation should I request from a supplier?

Ask for usable panel coverage, compatible feet and couplers, installation instructions, test or design documentation for the selected configuration, limits on screens or signs, inspection guidance, coating details, gate options, and a complete delivered-price quote.

Planning quantity only. Enter each continuous run separately and omit gate openings. Wind design, ballast, accessories, and code compliance need separate review.

Continuous fence run lengths

In metres. Separate distinct runs with commas or new lines; omit gate openings. Maximum combined run: 5,000 m.

Usable panel cover width

Use the supplier's usable cover width, not frame outside width. Range: 0.5–6 m.

Panel type

Panel type is copied into your RFQ; it does not change the quantity formula.

Worked panel quantity example

For separate runs of 18 m, 24 m, and 12 m using 2.4 m of usable cover per panel, round each run up: 8 + 10 + 5 = 23 panels. A 5% spare allowance adds 2, for 25 panels total. This is a reproducible quantity example, not a field case or a design approval.

Key decisions before ordering

A panel count is only one part of a safe, usable perimeter. The selected system, site conditions, local requirements, and documented installation method determine the rest.

Measure each run

Separate runs and openings so each run is rounded up to whole panels.

Check usable cover

Use the installed cover width supplied for the panel and joint detail.

Design for the site

Wind exposure, ground, screens, gates, and layout affect stability.

Verify local rules

Standards and permit requirements depend on location and project use.

Compare building site fence panel types

These are selection trade-offs, not standard dimensions or a product approval. Ask for drawings and usable cover dimensions for the actual model.

System type	Can suit	Check before choosing	Evidence to request
Welded mesh	Sites needing visibility and a modular boundary	Mesh opening, frame, connections, ground gaps, and climb access	Panel drawing, test/design information, and installation instructions
Chain-link	Projects with a compatible framed or tensioned system	Whether the fabric and frame provide the needed access control and durability	System configuration, connection details, and care guidance
Solid hoarding	Projects needing reduced visibility or a solid enclosure	Wind action, foundations or ballast, support spacing, and public interface	Site-specific engineering/design and installation details

“Anti-climb” is a product description, not a guarantee that a fence prevents access. Mesh geometry, top treatment, joints, adjacent objects, and maintenance all matter. Check the risk assessment and applicable requirements for the project.

Site-specific designScreens change the system

Treat wind stability as a design question

A generic wind-speed label or brace-per-panel rule cannot establish stability. The design must match the location, panel and footing system, ground, connections, and any screening or signage.

The estimator below counts panels. A qualified design or supplier documentation must determine stability for the actual site.

Inputs to verify

Give the supplier or designer the actual site configuration.

Site location, exposure, topography, and ground surface
Panel dimensions, connections, feet, and support system
Screen, shade cloth, banners, or other added surface
Returns, free ends, gates, corners, and nearby buildings

Stop and get the design checked

The panel estimator does not produce an engineering result.

Before installation, ask for written system limits and the design or test documentation for your configuration. Recheck if the ground, screening, layout, or weather exposure changes. In Australia, WorkSafe Victoria warns that temporary structures should account for severe weather and site-specific wind loads.

Wind-risk decision table

Condition	Why it matters	Next action
Mesh or open infill	The chosen product still needs an approved support configuration for the site.	Use the manufacturer's tested/design configuration.
Privacy screen or signage	Added surface can change the loads and supports required.	Get approval for the exact screen and fixing method before fitting it.
Hoarding, exposed site, or complex boundary	Site conditions and geometry can govern stability.	Obtain a competent, site-specific design and installation plan.

Check underground services before using anchors

Ground-penetrating stakes or anchors can encounter buried services. The required locating and notification steps depend on the work and the local jurisdiction.

Review site information

Check available utility records and mark-outs. Records may not show every service or its exact depth.

Use local locate procedures

Contact the relevant utility owners or one-call service and follow local notice periods before ground-penetrating work.

Choose a suitable footing

Surface bases avoid ground penetration but do not prove the fence will be stable. Use the approved system design.

OSHA 29 CFR 1926.651(b) applies to excavation work and requires estimated utility locations to be determined and owners contacted before excavation begins. Do not treat it as a universal rule for every type of fence stake; check the local requirements for the proposed work.

Check the rules for the project location

These sources have different scopes. None should be read as a single worldwide building site fence specification. The full standards may require purchase or access through a standards body.

Location / source	What it supports	Limit of this summary
Australia — AS 4687.1 and .2:2022	General design/conformance pathways and requirements for temporary fencing and pedestrian barriers.	Use the full current standard and applicable state or territory rules; this page does not reproduce clauses.
United States — OSHA 1926.34 and .502	Egress from occupied buildings/structures and employee fall-protection systems, respectively.	These rules do not establish one general height or design for every exterior site boundary. Check building, fire, public-way, and local requirements.
United Kingdom — HSE guidance	HSE describes a two-metre small-mesh fence or hoarding as typical in populated areas and says the site perimeter should reflect risks.	Guidance is not a universal statutory dimension for every site; assess the project and current local obligations.

Installation and inspection checks

Follow the instructions for the exact system and the project risk assessment. Inspect after changes in layout or weather and at the intervals required by the site plan.

Check	Look for	Action if it fails
Panels and connections	Damage, loose couplers, incompatible parts, or gaps at joints	Isolate the affected area and repair or replace per supplier instructions.
Feet, anchors, and ground	Movement, sinking, rocking, or a changed ground surface	Stop and restore the approved footing arrangement; recheck the design if conditions changed.
Screens and signage	Added material, tears, loose ties, or changes from the approved setup	Remove or secure only as instructed, then get the wind design reviewed.
Gates and access	Safe operation, clear routes, secure closure, and emergency arrangements	Follow the site emergency plan and applicable rules; correct defects promptly.
Public interface	Trip hazards, protrusions, access gaps, and changed pedestrian routes	Make the area safe and coordinate with the site lead or relevant authority.

Review component options alongside the site-specific design and supplier documentation for your project.

Compare renting with buying using project quotes

There is no universal break-even month. The result changes with project duration, delivery, storage, losses, reuse, maintenance, and resale value.

Cost item	Renting	Buying	Evidence to collect
Initial cost	Delivery, setup, deposits	Panels, accessories, delivery, setup	Written itemized quote
Ongoing cost	Hire rate, extensions, damage/loss terms	Storage, maintenance, financing, handling	Rates and contract terms for the planned period
End-of-project value	Collection and return charges	Resale, reuse, or disposal	Realistic reuse plan and resale estimate

A practical comparison

Compare total hire cost for the planned duration against purchase and delivery cost plus ownership costs, then account for credible resale or reuse value. Use the same panel quantity and accessory scope in both quotes. If the inputs are uncertain, show a range instead of a single break-even date.
