Predictika · Temporary construction barricades

An AI sales agent's barricade order, checked before it goes out

An AI sales agent prepares an order for temporary construction hoarding or pedestrian fencing: height, wind speed, counterweights, stack spacing and fixings. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of the published engineering guide and returns a verdict, every reason and the figures it computed.

Scope: Lomax modular temporary barricades (hoarding) and safe pedestrian zone fencing, as resold by ARC in the US. See everything this validator covers

This validator models orders for Lomax counterweight hoarding (indoor and outdoor) and Lomax fencing, using the Lomax Installation and Technical Guide that ARC publishes, not just the scenarios shown below.

  • Indoor hoarding — panel heights of 120 to 800 cm, the counterweights per stack the guide gives for each height, stack spacing (120 cm, or 240 cm at 120 cm high), double studs and two cross beams above 600 cm, screw spacing, 12 mm minimum panel thickness and at least 3 panels. Indoor double stacks go to approval.
  • Outdoor hoarding — heights up to 400 cm, single and double stacks at the 120 cm or 60 cm spacings the tables list, the counterweights per stack for the design wind speed (the columns of the guide tables, 10 to 29 m/s; heights, winds and spacings the tables mark N/A or do not list go to approval) and the safety rod length for double stacks (3+3 to 20+20).
  • Fencing — two base counterweights per support at up to 240 cm, and the saddle weights the guide gives at its listed wind speeds up to 39 m/s (shade cloth is tabled at the 15 m/s class only).
  • Order — the stacks must cover the run, and the counterweight mass stated on the order is compared with the computed mass (18 kg counterweights, 30 kg saddle weights).

Any Lomax hoarding or fencing order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (ARC offers barricades per project for rental, lease or purchase with no public price list, so this validator produces no price build-up or line-item list), the SwiftWall modular wall systems, doors and kiosk layouts, graphics and printing, and installation services.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Counterweights that depend on height, wind speed and spacing togetherOnly with workarounds
The count comes from a table with several dimensions; a rules-based CPQ needs a lookup table kept in step with the guide.		The count is computed from the height, wind speed, stack type and spacing on every call.
Wind speeds and spacings that are not in the guide tablesOnly with care
Someone has to decide what happens off the table and encode it for every table.		Values the tables do not list, and combinations they mark N/A, come back as approval findings.
Safety rod length for double stacksOnly with care
A second table keyed on the counterweights per stack, easy to leave out.		The rod length is computed and compared with the rod on the order.
Stacks that must cover the run at the allowed spacingOnly with care
A run length, a spacing and a stack count have to be multiplied and compared across lines.		Coverage and total counterweight mass are computed and compared with the stated mass.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The order has 3 counterweights per stack; the guide calls for at least 4 for this setup.
2The order has 11 counterweights per stack; the guide calls for at least 12 for this setup.
3Hoarding taller than 600 cm needs double vertical 90 x 45 studs; the order has single studs.
4The order has 1 horizontal cross beam(s); the guide needs one up to 600 cm and two above 600 cm.
5The panel height on the order is 900 cm; the Lomax guide covers freestanding hoarding from 120 cm up to 800 cm indoors and up to 400 cm outdoors.
6The panel height on the order is 100 cm; the Lomax guide covers freestanding hoarding from 120 cm up to 800 cm indoors and up to 400 cm outdoors.
7The panels on the order are 10 mm thick; the guide requires panels of at least 12 mm.
8The order has 2 panels; the guide needs at least 3 panels for the configuration to be certified.
9The panel screws on the order are 600 mm apart; the guide allows 400 to 500 mm up to 600 cm high and 400 mm above that.
10The panel screws on the order are 450 mm apart; the guide allows 400 to 500 mm up to 600 cm high and 400 mm above that.
11The spacing on the order is 150 cm between stacks; the guide allows at most 120 cm for this setup.
12The spacing on the order is 250 cm between stacks; the guide allows at most 240 cm for this setup.
13The run is 720 cm but the stacks on the order cover only 480 cm at that spacing.
14The order has 14 counterweights per stack; the guide calls for at least 15 for this setup.
15The guide tables do not give a counterweight count for this height, wind speed and stack spacing (N/A, a wind speed or spacing that is not a table column, or beyond the table); the Lomax outdoor configurator or Lomax should confirm the configuration.
16The order has 9 counterweights per stack; the guide calls for at least 10 for this setup.
17The order has 12 counterweights per stack; the guide calls for at least 13 for this setup.
18The order has 7 counterweights per stack; the guide calls for at least 8 for this setup.
19The panel height on the order is 500 cm; the Lomax guide covers freestanding hoarding from 120 cm up to 800 cm indoors and up to 400 cm outdoors.
20The order has 4 counterweights per stack; the guide calls for at least 5 for this setup.
21The safety rod on the order is 30 cm; a double stack of this size needs a rod of at least 40 cm in the rear stack.
22The safety rod on the order is 0 cm; a double stack of this size needs a rod of at least 40 cm in the rear stack.
23The guide describes indoor double stack configurations as pre-certified on request; contact Lomax for the counterweight count.
24The safety rod table in the guide covers double stacks of 3+3 to 20+20 counterweights; the order has 21 per stack, so the rod length should be confirmed with Lomax.
25The order has 1 counterweights per stack; the guide calls for at least 2 for this setup.
26The fence run has 1 saddle weight(s) per support; the guide calls for at least 2 at this wind speed.
27The fence run has 0 saddle weight(s) per support; the guide calls for at least 1 at this wind speed.
28The fencing table covers wind speeds up to 39 m/s, and shade cloth only at the 15 m/s stability class; the wind speed or shade cloth on the order is not a column of it, so confirm the saddle weights with Lomax.
29The spacing on the order is 260 cm between stacks; the guide allows at most 240 cm for this setup.
30The order states 300 kg of counterweight, but the stacks on it come to 324 kg.
31The order states 1,900 kg of counterweight, but the stacks on it come to 1,800 kg.
32The panels on the order are 9 mm thick; the guide requires panels of at least 12 mm.
33The order has 0 horizontal cross beam(s); the guide needs one up to 600 cm and two above 600 cm.
34The panel screws on the order are 700 mm apart; the guide allows 400 to 500 mm up to 600 cm high and 400 mm above that.
35The run is 1,200 cm but the stacks on the order cover only 450 cm at that spacing.
36The order states 1 kg of counterweight, but the stacks on it come to 108 kg.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for temporary construction hoarding or pedestrian fencing: height, wind speed, counterweights, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of the published engineering guide and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for indoor hoarding 1,440 cm long and 360 cm high: 12 single stacks of 3 counterweights about every 120 cm. The order states 648 kg of counterweight. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The panel screws on the order are 600 mm apart; the guide allows 400 to 500 mm up to 600 cm high and 400 mm above that. The order has 3 counterweights per stack; the guide calls for at least 4 for this setup.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for counterweights that depend on height, wind speed and spacing together, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the counterweights per stack to 4, the screw spacing to 450 mm and the stated counterweight mass to 864 kg.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
