Module 4

Advanced Design & Standards

Optimizing operations with advanced drops, 3D coordination, and standardized prototype designs.

4.1Fuel Delivery Methods

Gravity Drop (Standard)

Used for Underground Tanks (UST). The tanker truck uses gravity to empty fuel. Fast (300-400 GPM) and safe.

Requires 4" drop tubes

Pumped Drop

Required for Aboveground Tanks (AST) since the inlet is higher than the truck. Slower and higher risk of overfill.

Must use dry-break couplers

4.2Remodeling & Compliance

Key Challenges in Retrofits

  • Tank Relining: Instead of replacing a UST (costly), an epoxy liner can add 10-20 years of life.
  • Dispenser Upgrades: Switching to EMV (chip readers) often requires new, larger conduits for data cables.
  • Grandfathering: Knowing which parts of the code apply to "existing systems" vs "new construction" is vital for budget control.

4.3BIM & 3D Coordination

Building Information Modeling (BIM) prevents costly field clashes. By modeling underground utilities (sewer, water, electric, fuel) in 3D using Revit or Civil 3D, we ensure pipes don't intersect.

Collision Detection (Navisworks)

Interactive Exercise

Categorize the prototype strategy considerations.
