About us

We are a Malaysian, BEM-registered engineering consultancy led by Professional Engineers with Practising Certificates. From feasibility and detailed design to authority approvals and construction supervision, we deliver energy, water and infrastructure projects that are designed to code, approved without surprises and built to last.

Who we are

Built by
engineers

Sari Muhibbah Consulting (SMC) brings civil and structural, electrical, mechanical and renewable-energy engineering under one roof, led by three PEPC-holding directors. We take projects from site selection and feasibility through detailed design, authority approvals and construction supervision, and we handle the land, liaison and stakeholder work that decides whether a project gets built.

Design that
gets approved

Every study we issue is written for the people who have to sign it off: the Energy Commission, SEDA, TNB, state authorities, lenders and the local council. Terrain, geology, grid and permitting are addressed first, so the design survives contact with the approval process.

Delivering great projects

Leading by example

We care

Engineering should meet today's need and leave a more resilient country behind it.

Engineering excellence

Designs checked against the code, the site and the approving authority before they leave the office.

Empowering sustainability

Renewable generation and efficient systems designed into the brief, not bolted on at the end.

Safety & compliance

Every project delivered to Malaysian local, state and federal requirements, without surprises at approval.

Partnership

Close working with clients, authorities and communities, so decisions are made once and made well.
