Metro Rail Expansion
Project Overview
A major metro rail line extension spanning 4 new stations and 9 miles of elevated and at-grade track. ATF World served as the lead coordination consultant, delivering architectural, structural, and multi-discipline coordination for station buildings, platform canopies, and the elevated guideway structure. The project required seamless integration between the transit authority’s existing asset models and the new construction design.

Project Story
From challenge to resolution — how we delivered results.
Challenge
Each station had a unique architectural design language while sharing common structural and MEP systems, requiring an execution plan that balanced standardization with customization. The transit authority mandated compliance with their existing asset information requirements (AIR), which had to be embedded in every model element for handover to their FM system. Coordinating 38 federated models from 7 design firms was a significant logistical challenge.
Solution
ATF World established an execution plan with standardized templates, naming conventions, and requirements across all firms. We built custom scripts to automate AIR compliance checking, reducing manual QA time by 60%. Our coordination team ran weekly model federation reviews, issuing structured reports with resolution assignments and SLA-tracked turnaround times.
Result
Multi-discipline coordination achieved a 27% improvement in issue resolution efficiency versus the transit authority’s benchmark. All four station models passed the owner’s AIR validation on first submission — a first for the agency. The project was delivered 6 weeks ahead of the milestone schedule, enabling the design-build contractor to begin procurement earlier than planned.
