ORASKO – Smarter Substation Design with primtech

ORASKO is a fast-growing EPC contractor based in Malaysia, specializing in the construction and engineering of electrical substations. With over a decade of experience in substation projects, Ts. Mohd Zulhairi Che Harun, Head of the Design Department, knows the ins and outs of balancing efficiency, safety, and precision. ORASKO handles around 10 to 15 substation projects in parallel each year – a dynamic environment where accuracy in design isn’t just nice to have, it’s essential.

The Challenge

Before switching to primtech, ORASKO relied on 2D AutoCAD for their substation designs. While workable, this approach came with serious limitations. It left too much to the imagination, especially for engineers unfamiliar with the physical layout of substations. Misinterpretations were common, and clashes between design and reality often became painfully visible on site – when changes were already costly.

For ORASKO as a contractor, every design mistake meant delays, budget overruns, and added pressure.

The Solution

In 2017, ORASKO took the leap and introduced primtech 3d into their workflow. It quickly became a game-changer. Design reviews suddenly made sense even to engineers with no field experience. “primtech leaves less room for false imagination, because designing in 3d makes so much more sense” says Zul.

His team can now visualize substations in detail, run clearance and phase checks early in the process, and onboard newcomers with ease. And one of the most impactful changes: the design team is now actively involved in the tendering process.

Before primtech, the design department only came in after a project had been won. Tenders were based on rough estimates and Excel-based assumptions. That often led to cost gaps and project risks. Now, using the detailed 3D data from primtech, Zul’s team can provide accurate quantities and bill of materials upfront. This makes the tender documents more complete, realistic, and competitive – while also reducing surprises down the road.

The result? Fewer errors, faster workflows, and a noticeable boost in quality and confidence across the entire project lifecycle.

The results:

	Higher Design Accuracy Design errors are caught early – not on-site. This shift alone has saved ORASKO countless hours and costs. Mistakes that used to only be discovered during construction can now be avoided entirely.
	More Reliable Phase and Clearance Checks Especially for brownfield projects, fitting new components into existing substations requires pinpoint accuracy. primtech 3d gives them the tools to ensure everything fits – digitally, before anything is built.
	Improved Tendering Process Zul’s team now supports the tender phase with detailed, validated designs. This allows for more accurate cost calculations and reduces reliance on manual estimates.

With primtech, new engineers don’t need years of on-site experience to understand what they’re designing. The 3D model speaks for itself.
