Bongshai Engineering & Construction provides full EPC (Engineering, Procurement, Construction) services for electrical substations, heavy industrial power cabling, grid transmission line civil foundations, and solar energy installations. Operating in compliance with Bangladesh Power Development Board (BPDB) and PGCB electrical standards, we ensure high-efficiency power distribution for industrial plants.
Civil transformer pad construction, oil retention pits, GIS/AIS switchgear room civil works, lightning arrester installations, and earth grid ground mat testing.
Heavy engine foundation blocks for 100 MW HFO power plants, cooling tower RCC structures, fuel tank bund walls, and heavy pipe bridge support structures.
Industrial factory rooftop solar PV array framing, net-metering grid synchronization, central string inverters, and high-efficiency solar power generation.
Armored High Tension (HT) and Low Tension (LT) underground cable trench excavation, ladder-type cable tray erection, busbar trunking, and main distribution panels (MDP).
Automatic Transfer Switch (ATS) panels, multi-generator load-sharing synchronization systems, Motor Control Centers (MCC), and PLC-driven industrial automation.
20m to 30m motorized high-mast floodlight towers for sea ports, highway junctions, industrial factory laydowns, and stadium facility lighting.
Constructed heavy engine foundation monoliths, fuel tank RCC retaining bund walls, 33kV substation yard civil structures, and heavy drainage networks for the 100 MW HFO Power Plant project in Katakhali.
We operate in strict compliance with Bangladesh Power Development Board (BPDB) and PGCB electrical standards, ensuring that all substations, cabling, and solar PV integrations meet national safety and efficiency codes. For solar projects, we coordinate net-metering approvals with local distribution companies including BREB, DESCO, and DPDC.
We perform 4-point Fall-of-Potential Earth Resistance Testing using calibrated Earth Testers to guarantee grounding grid resistance below 1 Ohm per IEEE 80 standards prior to energization.
Yes, our power division handles complete net-metering approval documentation, bi-directional energy meter installation, grid protection relays, and compliance verification with local power distribution companies (BREB, DESCO, DPDC).
