Predictika · Drywall partition system quotes in euros

A sales agent's partition wall quote, checked before it goes to the contractor

A sales agent prepares a quote for a drywall partition wall and says it is ready to send. Before it goes out, the agent sends it to Predictika's validator, which checks the board, the studs, the layers, the fire and sound requirements, the height, the destination, the delivery time and the discount together, prices the wall, compares the total the agent states with its own, and reports every problem it finds in one pass.

Scope: Quotes for a Knauf-style gypsum drywall partition system: five boards, three stud widths, finish levels, insulation, and destinations in Germany, France, Poland, the Netherlands and the United States, in euros. Built from general public knowledge; not affiliated with Knauf. All prices and limits are estimates for demonstration. See everything this validator covers

This validator checks any quote of this kind against the rules below, not just the scenarios shown.

  • Fire and sound performance — the fire resistance and sound reduction the build-up reaches from board, layers, studs and insulation, against what the project requires.
  • Board and use — a moisture resistant board for a wet room, a high density board for high impact use, and the board length against the wall height.
  • Studs and spacing — the wall height each stud allows at the chosen spacing and layer count, the system spacings of 300, 400 and 625 mm, and the insulation against the cavity.
  • Destination and delivery — whether each board and stud is offered in the destination, and the delivery time against the days the customer needs.
  • Price, discount and the stated total — the order price, the small order and large order reviews, discount authority by channel, and a check that the net total the agent states matches the total the validator computes.

Any partition quote that touches these rules is in scope, not only the scenarios pictured here. Not checked: other Knauf products and systems, real list prices and contracts, structural engineering or code approval, installation labor, and taxes.

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

    
What the validator caughtA rules-based CPQPredictika
A result built from several partsOnly with workarounds
The fire resistance and sound reduction come from the board, the number of layers, the stud width and the insulation together, so each combination needs its own rule or a lookup table that someone has to keep.		The performance of the whole build-up is computed from the request, and the finding states what it reaches against what is required.
Limits that depend on each otherOnly with care
The wall height a stud allows depends on the spacing and the number of layers, and the board length adds another limit, so the rule list multiplies.		Board, studs, layers, spacing, height and destination are fields of one request and are re-evaluated together on every call.
A total the agent statesOnly with workarounds
A form validator rarely sees the agent's own total, so an agent can state a number that differs from the price list and nothing notices.		The stated total travels in the request and is compared with the validator's own calculation.
A block that is also an approvalOnly with care
A wall taller than the board needs technical service while a wall taller than the stud allows is blocked, and a small order needs approval, so each limit needs guarded rules.		Blocks and approvals come back together, each with its reason, and the verdict follows from both.
Every problem returned in one answerOnly with workarounds
Form checks usually stop at the first failing field, so the sales agent 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
Click to expand
    
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 build-up must reach the fire resistance and sound reduction the project requires; fire board, extra layers and insulation each add to the result.
2A wet room needs a moisture resistant board, and high impact use needs a high density board.
3The wall height may not exceed what the stud and layer count allow at the chosen spacing; a wall taller than the board length needs technical service to confirm the rating.
4Stud spacing must be a system spacing of 300, 400 or 625 mm, and the insulation must fit the stud cavity.
5A board or stud must be offered in the destination country, and a Q4 finish needs the full skim coat.
6The expected delivery time must not exceed the days the customer needs.
7A discount above 5 percent needs approval, and a discount above the limit for the order channel is blocked.
8A wall under 15 square meters needs sales approval for a small order surcharge, and a net order value above EUR 40,000 needs a sales director review.
9The net total the agent states must match the total the validator computes.

1. A fire-rated wall built with the wrong board: A 60-minute fire wall built with standard board

    
The agent's request. Please check this quote for Haldane Interiors: a drywall partition wall in Germany, Standard board GKB 12.5 mm, two layers of board per side on CW 75 studs at 625 mm, 3000 mm high and 12 meters long, with 60 mm of insulation, Q2 finish, 60 minutes of fire resistance and 50 dB of sound reduction required, needed within 20 days, ordered through a contractor. Net total EUR 1,194.75. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Fire resistance not reached. This build-up achieves 0 minutes of fire resistance, and 60 minutes are required.
    • 
      
  • Estimated price. The validator computes EUR 1,194.75 net for 36 square meters, which is the total the agent states. All prices and limits are estimates for demonstration.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. A sales agent prepares a quote for a drywall partition wall and says it is ready to send. Before it goes out, the agent sends it to Predictika's validator, which checks the board, the studs, the layers, the fire and sound requirements, the height, the destination, the delivery time and the discount together, prices the wall, compares the total the agent states with its own, and reports every problem it finds in one pass.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please check this quote for Brightwater Builders: a drywall partition wall in Germany, Fire board GKF 12.5 mm, two layers of board per side on CW 75 studs at 625 mm. Net total EUR 1,147.77. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding, all in one answer. A wet room needs a moisture resistant board, and the Fire board GKF 12.5 mm is not.
    6. 
      
  6. The validator returned one blocking finding 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 limits that depend on each other, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the board to Fire and moisture board GKFI 12.5 mm and the stated net total to EUR 1,359.93.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The earlier finding is cleared.
    13. 
      
  13. One problem 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.
