MRT Line -1&5 Utility Shifting Project announcement to BNF

BNF with MRT Line-1&5 

BNF Engineers Ltd. is awarded the MRT Line -1&5 Utility Shifting Project. Specifically, BNF is engaged in EHV Underground Cable Power Transmission Lines Works.

Project announcement summary

BNF Engineers Ltd. has been awarded the MRT Line -1 & -5 Utility Shifting Project and will perform EHV underground cable power transmission lines works for the contract. This covers planning, design, procurement, installation, testing, and commissioning of EHV underground power transmission infrastructure required to support MRT Line -1 and Line -5 utility relocations.

Scope of work

• Survey and site investigation: detailed utility mapping, geotechnical checks, and as‑built verification.
• Design and engineering: detailed cable routing, ductbank and manhole design, cable sizing, protection coordination, earthing and lightning protection, and civil interfaces.
• Procurement and logistics: supply of EHV cables, joints, terminations, ducts, manholes, cable trays, protection relays, and ancillary materials.
• Civil works and installation: excavation, ductbank construction, manhole installation, cable laying, jointing, backfilling, and reinstatement.
• Testing and commissioning: insulation tests, sheath tests, joint verification, protection relay setting and testing, and system integration tests.
• Handover and documentation: O&M manuals, as‑built drawings, test reports, and training for client operations staff.
• Coordination and traffic management: utility coordination, traffic diversions, public safety, and stakeholder communications.

Key deliverables

• Detailed design package including drawings and protection coordination studies.

• Procured EHV cable system and associated civil components.

• Installed and commissioned the EHV underground cable system along the agreed corridors.

• Complete test and commissioning reports and final as‑built documentation.

• Traffic management and reinstatement to pre‑work condition or better.

Risks and mitigations

• Undiscovered utilities or site conditions — mitigate with pre‑construction CCTV, potholing, and contingency allowances.
• Traffic and public disruption — mitigate with detailed traffic management plans, night works where feasible, and public notices.
• Permitting delays — early engagement with authorities and submission of complete permit packages.
• Supply chain or long‑lead items — early procurement, alternative suppliers, and buffer stock.
• Safety and quality — enforce strict HSE plan, qualified jointing teams, third‑party testing, and QA inspections.
