RCC Box Culvert #20 - Naria Upazila
Designed and executed under full structural engineer compliance, utilizing slump consistencies, cylindrical testing, and grade validation.
Project Overview & Scope
This project was executed under the SDF rural infrastructure development program to bridge a natural agricultural canal that flooded during the monsoon, cutting off agricultural transport. A high-durability 2.0m x 2.0m RCC Box Culvert was constructed with robust wing walls.
“This subproject is part of the community-driven micro-financing initiative co-financed by local villagers and the Social Development Foundation. It aims to empower community communication, bypass flood blockages, and promote district connectivity.”
