"We tried configuring the 12 Retaining Wall services using the existing generic Service/Product creation screens. Because the current engine sums product quantities into the service area and stacks all equipment/labor hours additively, a standard $5,800 Retaining Wall inflates to over $80,000. To support the PDF, we must implement the dedicated Retaining Wall Parametric Estimator within the With-Request Flow as documented in our Gap Analysis."
