A typical GA drawing includes:
Tank model
Identifies exactly which product and configuration is being supplied, so there's no ambiguity between quote, drawing, and delivered tank.
Tank capacity and safe fill levels
States the tank's rated volume and its safe fill level (SFL), the maximum amount of fuel the tank should hold in practice, accounting for thermal expansion and venting requirements.
Tank weight
Both empty and full weights matter here, since they affect the base or foundation design, lifting equipment needed on installation day, and any structural considerations for the site.
Tank dimensions
Overall length, width, and height, along with the position of key fittings, so installers and site engineers can confirm the tank will physically fit and connect where it needs to.
Fittings
Everything included with the tank, ports, valves, gauges, vents, and any deviations from the standard configuration that were agreed to during the quote process.
Accessories
Add-ons such as walkways, spill containment, or other site-specific extras that were included as part of the build.
Customer-specific notes
A space to capture any project-specific requirements or clarifications that don't fit neatly into the standard drawing fields, so nothing gets lost between conversations and the final build.
