Box Culvert Design & Detailing Process
We work from your project brief, hydraulic requirements, and site conditions to produce fully coordinated precast box culvert drawings.
Requirement Gathering
We collect all project inputs, hydraulic opening sizes, load classifications, soil cover depths, and site constraints. This ensures every design decision is grounded in your actual project conditions before detailing begins.
Structural Sizing and Cell Configuration
Our team determines the culvert dimensions, wall and slab thickness, and single or multi-cell arrangement based on loading and flow requirements. Standard or custom profiles are developed at this stage.
Reinforcement Detailing and BBS Preparation
We produce fully detailed reinforcement drawings with bar marks, spacing, cover specifications, and a complete Bar Bending Schedule, formatted for direct use by your casting yard.
Mould Drawing, Review & Issue
Casting-specific shutter drawings are prepared, reviewed internally, and coordinated with your fabrication team until the full package is production-ready and approved for casting.
