Fencing · Palissade

Fencing · Palissade draws site fence plans: a hoarding around a scaffold along a street, or the fence of a lot. You describe the site to your assistant, which prepares the plan with Fencing.

The requests on this page are examples. Put them in your own words. For complete examples, read the tutorials Fencing around a scaffold and Fencing a simple perimeter.

What you receive

For each plan, you receive:

• the PDF plan in A3 format: the dimensioned plan view, the bill of materials, the points to note and the assumptions. The last sheet, “Terms and legend”, explains each term and each symbol;
• the bill of materials in Excel and CSV;
• the “Part codes” annex as a PDF, when the plan uses the parts in your library. It gives, for each part, its item number, its code and a QR code that carries the code.

Fencing produces no CAD plan (DXF) and no 3D model.

Each file carries a TektonAI reference that proves where it comes from. See Check that a document comes from TektonAI.

What you can ask

You ask	What Fencing does
“Prepare the hoarding around the scaffold of plan ECH-261022-A2E0: 1.5 m clearance, mesh panels, using the fences in our library. The site is in Montréal.”	Reads the scaffold length, the frame width and the distance from the wall in the Scaffold plan, then draws the hoarding on three sides up to the wall, with the workers’ gate and the public walkway on the street side.
“Prepare the fence of a 40 m x 25 m rectangular site in Montréal, with mesh panels.”	Draws the fence of a perimeter, open or closed, given side by side or corner by corner.
“Without producing a plan, calculate the fence and give me the parts list.”	Calculates the fence and the bill of materials, without producing files.
“Show plan CLO-261023-E221.”	Gives the plan’s data, its saved answers, the history of its revisions and the links to its files that are still valid.
“Revise plan CLO-261023-E221: increase the clearance to 2 m.”	Produces the next revision of the plan. Takes all its data, applies only the requested change and adds the revision to the revision table.
“To keep the fence standing in the wind, I want a ballasted brace at every panel where it fits, with 251 kg of ballast on each base.”	Produces the revision that holds the fence against the wind, with the ballast in the bill of materials. See below.
“Place a 3 m by 10 m site trailer in the north-west corner: does it get in the way of the fence?”	Flags a trailer or a zone that crosses the fence line, sticks out of a closed perimeter or overlaps another one.
“Check the reference of this plan.”	Says whether the reference is authentic and compares the file received with the file delivered.

Around a scaffold

Give the Scaffold plan number (ECH-…). Without a Scaffold plan, give the length of the scaffold along the façade, the frame width and the distance from the wall yourself.

Fencing also asks you for:

• the clearance between the scaffold and the hoarding. It has no default value;
• whether a pedestrian gate is needed for the workers, and its width;
• whether a public walkway is needed between the hoarding and the street, and its width.

The plan flags the parts inside the scaffold footprint, with a geometric clearance of 0.60 m (2’-0”) around it. This clearance is a design assumption, not a regulatory minimum. The plan then offers two choices: a wider clearance, or removing those stays and holding the fence by the ballast on its bases.

The form questions

Before drawing, Fencing asks its questions in a form, all at once:

• the site relief: hill, ridge or escarpment;
• the importance category of the fence for wind (NBC 2020, Table 4.1.7.3);
• the fence height, when your library has panels of several heights;
• the part to use for a role (base, stay), when your library has several.

With a scaffold plan, the form also asks about the workers’ gate and the public walkway.

Other missing values do not block the plan. The plan comes out, with a line for each check it could not make:

• “Lot line not provided: the plan does not check whether the hoarding or the public walkway goes past it.”
• “Lateral lot lines not provided: passing in front of the neighbours not checked.”
• “Worker access to the scaffold not checked: width not provided.”

When you have the information, answer the questions: the next revision makes the check.

Wind restraint

Fencing checks the panels for overturning under the site wind, following NBC 2020: the 50-year wind of the locality, with conservative assumptions.

It needs the measurements from your fence records in your Parts · Remise library. Without them, the plan says that wind overturning is not checked.

When the bases alone do not hold the panels, the plan says so under “OVERTURNING” and asks how to hold the fence. It offers two choices:

• ballast on every panel base, without intermediate stays;
• a ballasted stay at each panel where it fits, fixed to the panel and to its base, with ballast on each base.

The plan calculates the ballast for each choice. You choose, and you give the ballast weight you place on each base. The next revision adds the stays and a “Base ballast” line in the bill of materials. The “OVERTURNING” point is then replaced by “WIND RESTRAINT”, for example:

WIND RESTRAINT: a ballasted stay at each panel where it fits, fixed to the panel and to its base (5 more stays), and 251 kg of ballast on each panel base (18 bases, 4,518 kg in all), the user’s choice. Moment ratio: 1.00. Conservative calculation (50-year wind, NBC 2020): a competent person checks it before installation.

The rental company’s data sheet or signed calculation for your fences takes precedence over this calculation.

Gates and access

• Give the width, the segment and the position of each gate, pedestrian or vehicle.
• Fencing uses the gate leaves in your library meant for that kind of opening, otherwise panels on wheels.
• A closed fence with no gate is flagged: “No gate and no entrance: how do workers and vehicles get in? Add a pedestrian or vehicle gate, or say how the site is reached.”

The parts

• Panels are laid end to end, with as few panels as possible. No panel is cut: when a run does not come out even, the last panel overlaps the one before.
• A base at each post position, clamps at the joints, and a stay with its base at each corner and at each end of the fence.
• The fences in your Parts · Remise library replace the generic parts, with your part numbers and weights. A part missing from your library stays generic and is marked “Not in … catalogue”, with your company’s name.

Revisions

• Only the company that produced a plan can revise it.
• The name of the employee who made each revision is printed in the plan’s revision table.

Good to know

Plans are preliminary. Each plan says so: “This plan is not approved for installation: it is for preparing the fence and having it checked.” A competent person checks it before installation.

Fencing gives no prices.
