What engineering capabilities does Bongshai E&C provide?
BONGSHAI E&C has the resources and domain knowledge to execute any engineering job — including Civil construction, Building construction, Architectural works, Steel structure fabrication and erection, Pre-engineered steel buildings (PEB), Mechanical construction, Electrical system installation, and Electro-mechanical engineering. The company maintains a highly skilled team of graduate engineers, diploma supervisors, certified foremen, and skilled workers capable of executing any complex project, anywhere, under any circumstance.
The engineering division at BONGSHAI E&C operates as the technical backbone of the EPC&C model. Before any project enters the field, the engineering team produces comprehensive structural calculations, code-compliant drawings, material specifications, and method statements. This pre-construction engineering investment significantly reduces on-site rework, protects project schedules, and ensures the final structure meets or exceeds client and regulatory expectations.
All engineering work is performed in strict accordance with BNBC 2020 (Bangladesh National Building Code), AISC 360-22 (for steel structures), ACI 318-19 (for reinforced concrete), and relevant IEC and NFPA standards for electrical and fire safety systems. Where international clients require Eurocode compliance, the team adapts accordingly.
What structural design codes and standards does Bongshai E&C follow?
Every structural engineering deliverable from BONGSHAI E&C is anchored to internationally recognized codes. This ensures that clients receive structures with well-documented safety factors, predictable behavior under design loads, and regulatory acceptance across all government and third-party inspection agencies.

How does Bongshai E&C use an Integrated Construction Management System on site?
BONGSHAI E&C maintains a powerful, structured Construction Management System (CMS) that is embedded across every project from Day 1 of mobilization. The CMS is designed to reduce construction time, minimize cost overruns, and deliver higher quality than industry norms. It operates across six integrated modules:
Site Administration
Site office setup, permit management, daily site diary, subcontractor management, and direct client communication. Site manager reports daily to the project manager on progress, constraints, and upcoming activities.
Materials Management
Approved vendor material delivery schedule, inward material inspection (rebar mill cert, cement test, structural steel MTR verification), material storage management, and daily consumption tracking to prevent wastage.
Workforce Management
Daily labor muster roll, productivity tracking by trade (concrete gang, rebar gang, steel erection crew, electrical crew), overtime authorization, safety toolbox talks, and welfare management including PPE issue records.
Equipment Management
Daily equipment utilization log, preventive maintenance scheduling for cranes, excavators, concrete pumps, and batching plants. Breakdown response protocol with spare parts inventory maintained at site store.
Quality Control
ITP (Inspection and Test Plan) hold points at every structural milestone. Concrete cube testing per BS EN 12390, weld inspection per AWS D1.1, bolted connection torque check, rebar coupler test, and dimension check against approved drawings.
Commissioning & Maintenance
Pre-commissioning walk-down, punch list management, system testing (electrical loop checks, plumbing pressure tests, HVAC air balance), mechanical completion certificate, and 12-month defect liability period support with dedicated maintenance team.
