How a project runs
From first enquiry to handover
BONGSHAI E&C's EPC&C model integrates all four phases of project delivery under a single contractual responsibility, eliminating coordination gaps between designer, supplier, contractor, and commissioner.

Delivery
How does Bongshai E&C manage projects using the EPC&C methodology?
Engineering, procurement, construction and commissioning under one responsibility. This approach reduces project risk, accelerates schedules, and controls total cost of ownership for clients.
- 01
Engineering
Structural analysis, BNBC 2020 code compliance, AutoCAD 3D detailing, BIM coordination, soil investigation review, and design-for-constructability checks before any material is ordered.
- 02
Procurement
Vendor qualification, bulk material sourcing, steel section procurement (ASTM A36/A572, SS400, Grade-60 rebar), equipment hiring, and supply chain tracking across all disciplines.
- 03
Construction
On-site execution with our own crews, crawler cranes, concrete pumps, and batching plants. Daily progress reporting, QC hold points, and strict HSE enforcement throughout the construction cycle.
- 04
Commissioning
Pre-commissioning checks, punch list resolution, mechanical completion certificates, test runs, final load testing, and as-built documentation package handover to client operations teams.
