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

An AI sales agent prepares an order for a modular scaffold for a building contractor: working, facade or reinforcement scaffold, bay length and width, load class, number of lifts and decked levels, whether it is tied to the structure, and the stair tower. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product information and returns a verdict, every reason and the figures it computed.

Scope: PERI UP Flex modular scaffolding (working, facade and reinforcement scaffolds, Stair 75 and Stair 100 / 125): bay size, load class, tying, height, stairs, steel deck count. See everything this validator covers

This validator models orders for the PERI UP Flex scaffolding line, not just the scenarios shown below.

  • Bays and grid — PERI UP Flex works on a 25 cm grid, with steel decks 25 cm wide in lengths such as 250 and 300 cm; the model accepts bay lengths and widths on that grid, the number of bays, lifts and decked levels, and counts the steel decks needed.
  • Load classes — load classes 1 to 6 (0.75 to 6.00 kN/m²) under EN 12810 and EN 12811; PERI states that the 250 cm steel deck reaches load class 5 and the 300 cm deck load class 4, and the model sets limits for the other bay lengths.
  • Application — modular working scaffold, facade scaffold and reinforcement scaffold, with rules on tying to the structure, free-standing height against base width, and facade load class.
  • Stair towers and height — PERI UP Flex Stair 75 and Stair 100 / 125, stair width, height limits and approval for tall scaffolds, plus the stated steel deck count compared with the computed one.

Any order for this line that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (this validator produces no price build-up or itemized list), PERI UP Easy, the Suspended Scaffolding and Working Platform LGS 150, PERI formwork and shoring products, engineering design for a specific site, and any national rules. Several limits are modeled by Predictika from comparable scaffold systems rather than published by PERI; the footer says which.

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
A load class that the steel deck length cannot carryOnly with care
The deck length and load class limits can be written as a table, but each new bay length means more rows to maintain.		Bay length, load class and application are checked together on every call.
A facade scaffold that is untied or too tall for its baseOnly with care
Tying and height rules depend on application, width and height at once; they are easy to write one at a time and miss in combination.		Application, tying, height and width are checked together.
A stated steel deck count that must match bays, decked levels and deck columnsOnly with care
A stated figure is a free-entry field; a rule can compare it with a calculation, but someone has to write and maintain that comparison.		The stated count travels with the order and is compared with the computed one on every call.
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.

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 a modular scaffold for a building contractor: working, facade or reinforcement scaffold, bay length and width, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product information 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 order a facade scaffold of PERI UP Flex: 24 bays of 300 cm by 75 cm, 6 lifts with 6 decked levels. The order states 2000 steel decks in total. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings and three approvals, all in one answer. Load class 5 is above what a 300 cm steel deck bay carries; the highest load class for this length is 4. The order states 2,000 steel decks; 24 bays on 6 decked levels with 3 decks across each bay make 432. A facade scaffold is anchored to the building; the order has it untied. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings and three approvals 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 a stated steel deck count that must match bays, decked levels and deck columns, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the bay length to 250 cm, the load class to 3, the tied to the structure to yes, the stair tower to Stair 75 and the stated steel decks to 432. It sets the stair width to 75 cm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All eight earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Eight 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.
