Works on Mile 6 Interchange flyover resume

KUCHING: The flyover project for the Mile 6 Interchange in Kuching has started to see some construction activities now after the issue on the presence of underground cavities was resolved, with only a few left to be tackled.

According to Lebuhraya Borneo Utara Sdn Bhd (LBU), the Mile 6 Interchange is one of the six interchanges to be built under Works Package 2 (WPC2) of the Pan Borneo Highway Sarawak (PBHS).

LBU project manager for WPC2, Dahlim Mungkil, said with the issue resolved, work at site is now very much focused on bored piling.

“At the same time while we do the piling work, you could see that four out of the 11 crossheads have already taken shape.

“We expect to do the beam launch for this 12-span flyover hopefully by January next year,” he said in a statement issued by LBU, which is still the project delivery partner for the PBHS.

According to the statement, the project team previously encountered the cavities in the limestone strata in the ground and this affected six out of the 11 piers.

The remaining piers are not affected based on the soil studies.

It explained that cavities are expected in limestone formation and hence, appropriate design and bore piling construction methods have to be executed to ensure the performance of the bore piles.

Before the pier work proceeds, pre-boring has to be done to find out whether there is any cavity in each of the 11 piers.

“Cavities have to be treated by filling them with concrete before the 1,000mm diameter bore piling works can be carried out.

After the bored piling, Dahlim said the project team would move on to do other works like pile caps and columns as well as the cross-head beams.

“We hope to complete this 430m-long flyover by end of next year,” he added.

Due to the busy traffic along the Kuching-Serian Road (KSR) where the flyover is, he said a dedicated traffic management team is put in place to manage and monitor traffic furniture while temporary street lightings are put up to ensure good visibility at the work site for public and road users.

Two out of the four lanes in the vicinity are closed to enable the construction works to be carried out.

In place for this is the widened road on both the Kuching and Serian bound routes to divert the traffic.

Samling Resources Sdn Bhd is the main contractor for WPC2 Sematan-Sungai Moyan stretch.
