Superior Electromechanical Services (SEMS) was established in 2013 in Dhaka, Bangladesh, with a clear focus on delivering reliable electromechanical engineering solutions to power, water, utility, and infrastructure sectors. Founded under the leadership of Engr. Mehedi Hasan Chowdhury, the company has grown steadily through disciplined execution, technical rigor, and long-term client trust.

From the outset, SEMS positioned itself not merely as an engineering-driven organization capable of handling design coordination, equipment supply, installation, testing, and commissioning of critical power and infrastructure systems. Over time, the company has developed a strong portfolio across government utilities, power plants, healthcare facilities, and industrial installations.

SEMS operates at the core of Bangladesh’s infrastructure ecosystem, supporting national authorities and large-scale projects in power generation, substations, water body management, water treatment facilities, and specialized installations. The company has successfully executed works for key public sector entities including the Bangladesh Power Development Board (BPDB), Bangladesh Atomic Energy Commission (BAEC), Bangladesh Water Development Board (BWDB), Dhaka Water Supply and Sewerage Authority (DWASA), Dhaka North City Corporation (DNCC) and other major utilities.
