DatumCorp International is a wholly-owned subsidiary of Selangor State Development Corporation (PKNS) and was established in 2012 to take charge of mixed development projects in strategic areas around Selangor. This project is a RM 1.2 billion transit oriented integrated development situated next to the Jelatek LRT station. A link bridge will be constructed to connect the station to Datum Jelatek. The mixed development comprises of 712 residential units over 2.29 ha and is linked to a 319,000 sq.ft of retail mall.

PKNS initially awarded the consultants from Surbana International Consultants (Malaysia) Sdn Bhd. The company had the Architects, C & S Engineers and M & E Engineers to start the design works for submission. After the final design works were completed, PKNS’s CEO, Datuk Othman Omar wanted to explore the Value Engineering (VE) exercise for the whole building structural elements and had the structural drawings re-designed to obtain millions of financial savings for the project. This was when Ir. Mohd. Fariz was employed to look into this re-design work back in July 2012 under a local VE Company at that time. Also, since the building was massive and had the first ring sky bridge in Malaysia, PKNS decided to conduct a wind tunnel testing in Canada (shown in pic)

Wind Tunnel Testing Canada

The project took Ir. M Fariz as far as Ontario, Canada to observe the wind tunnel testing lab with the client and other structural engineer principals on 24 July 2013.

CHALLENGE

It was the single largest high-rise building (176m tall, 42-story high) to be re-designed based from another engineer’s design and Ir Fariz had a few months to do it. He had to find savings from both the foundation structure and super structure.

SOLUTION

Fortunately, Ir Fariz was already well versed with 3D Finite Element (FE) software since his days in Australia. This time he had used them to replace the initial pile and pile cap foundation design to his raft pile design method (shown in soil pressure colour diagram).

RESULT

PKNS took the structural VE design work and found at least RM 20 million in structural cost savings.
