Frequently Asked Questions
How are payments structured?
Typical terms: 30 % PO, 30 % design freeze, 30 % FAT approval, 10 % shipment.
What if I request a design change after freeze?
Change orders are priced and added to the Gantt chart with adjusted ship dates before work proceeds.
Can you accelerate the build?
Yes—overtime shifts and parallel fabrication can compress the schedule if critical parts are available.
