ADB Reduced Risk and Optimized Planning with 5x More Options using Generative Design

Background

Problem

Rayerbazar WWTP is a new plant being planned by Dhaka WASA & proposed for Asian Development Bank (ADB) funding. The biggest risk factors for this project were the cost and time related to land constraints and acquisition. Dhaka is a dense city and it was imperative that the footprint of this WWTP be minimized as much as possible.

Solution

ADB uses TDG

TDG enabled ADB and Dhaka WASA to generate 10+ concept design options, compared to 2-3 options typically evaluated for a project.
Compact WWTP site-specific options included features like deeper reaction tanks, rectangular vs. circular clarifiers, and a phased facility build-out.

Results

Key Wins

Reduced project risk with 5x more compact design options
Streamlined project planning with data-driven insights
Expedited decision-making from 8-10 months to 8-12 weeks
“With Transcend’s generative design capabilities, we identified options that reduced project risk and cost by minimizing the facility’s footprint. Transcend sped up our decision-making by generating actionable data, including CAPEX, OPEX, and footprint information within hours.”
