The Problem & Bottlenecks

System Bottlenecks & Technical Friction

Bidding in California requires strict adherence to complex regional requirements including Title 24 energy efficiency mandates, Cal/OSHA standards, and county-specific prevailing wage rate sheets that cause generic estimating tools to fail.

Our Engineering Approach

Architecture Design & Implementation

We built a regionally specialized platform engineered around California construction economics. Integrated automated Title 24 material checklists, seismic framing calculators, and localized union/prevailing wage lookup tables across Los Angeles, the Bay Area, and San Diego.

Technical Architecture

System Subsystem Breakdown.

6 Core Subsystem Modules
