The Client & Context

Client: Upashahar Residential Apartment Community
Location: Upashahar Block C, Rajshahi
Completed: April 2026

The Operational Challenge

Building facade regulations prohibited haphazard exterior piping and visible water drip lines. The building also experienced summer voltage fluctuations that frequently damaged inverter compressors.

The Strategic Solution Executed

Designed an integrated mechanical riser shaft with UV-resistant concealed copper trunking, independent vibration-dampening roof brackets, and individual voltage surge suppressors for all 16 units.

"Our building facade looks pristine with zero ugly hanging pipes. Cooling is whisper quiet and our family electricity bills dropped noticeably in the first month!"

Engr. Mahmudur Rahman — President, Upashahar Residents Association
