Predictika · Concrete pipe and culvert quotes

An AI sales agent's concrete pipe quote, checked before it goes out

An AI sales agent prepares a quote for concrete pipe: precast reinforced pipe, pre-stressed pressure pipe or a precast box culvert, with a size, a duty, a joint, a load class, the cover over the pipe, add-ons, a quantity and a lead time. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the concrete pipe families named on the Orascom Construction site and returns a verdict and every reason.

Scope: Precast reinforced pipe, pre-stressed concrete pipe and precast box culverts (the National Pipe Company product families) with size, duty, joint, load class, cover, add-ons, quantity and lead time. See everything this validator covers

This validator models concrete pipe quotes of this kind, not just the scenarios shown below.

  • Product, size and duty — which nominal sizes each product is modeled in, gravity sewer and storm drain duty on precast pipe and box culverts, and pressure water duty (4 to 20 bar) on pre-stressed pipe with a steel ring joint.
  • Load class and cover — classes I to V, a 1 m minimum cover, class III or higher under more than 4 m of cover, and a structural check from 8 m.
  • Add-ons, quantity and lead time — sulfate-resisting cement for sulfate soil, epoxy lining only on precast pipe in a gravity sewer, installation supervision only with delivery, a 20-piece minimum, and approvals for rush orders, very large pipe and large volumes.

Any concrete pipe quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices, other Orascom or National Pipe Company products and non-concrete pipe. The product families are named on the Orascom Construction site; the sizes, limits and approval thresholds are modeled from typical industry practice and are not published by the company (see the note at the foot of the page).

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
Sizes that differ by productOnly with care
Each product is made in its own list of sizes, so a rule keyed to the product has to hold the list for each one.		The product and the size are fields of one request and are checked together on every call.
A product that fits only some dutiesOnly with care
Pre-stressed pipe is a pressure product and precast pipe is not, so a rule has to look at the product, the duty and the pressure at once.		The product, duty, joint and pressure are checked together on every call.
Options that depend on other choicesOnly with care
Sulfate soil needs sulfate-resisting cement, epoxy lining is limited to one product and duty, and supervision needs delivery, so a dependency rule has to sit beside each option.		Every option is a field of one request, so each dependency is checked on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for concrete pipe: precast reinforced pipe, pre-stressed pressure pipe or a precast box culvert. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the concrete pipe families named on the Orascom Construction site and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 120 pieces of pre-stressed pipe of 1,000 mm for a gravity sewer, with a rubber gasket joint, load class 2 and 6 m of cover. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. Pre-stressed pipe is a pressure product; use precast reinforced pipe or a box culvert for gravity sewer and storm drain duty. Pre-stressed pipe is jointed with a steel ring and rubber gasket; the plain rubber gasket joint is not available for it. 6 m of cover needs load class III or higher; the quote has class 2.
    6. 
      
  6. The validator returned three 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 a product that fits only some duties, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the product to precast reinforced pipe, the load class to 3 and the lead time to 6 weeks.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three 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.
