Wednesday, 20 February 2019, Miri: Ever wondered why construction works for the 6-span Miri Airport Interchange only takes place at night?
The simple reason for this unique situation is that construction activities have to comply with regulations set by the Department of Civil Aviation (DCA), specifically the obstacle limit surface, as the Miri Airport interchange is situated just a stone’s throw away from the airport runway.
“We can only work on the six spans, from Abutment A to Pier 6 of the interchange, from 11.30pm to 5.30am when the airport is free from flights landing and taking off.
“The reason is that our machinery, such as cranes and bored pile machines, cannot exceed the obstacle limit surface imposed by the DCA,” said LBU Construction Manager for Pujut Section, WPC 11, Michael Ting.
The construction team at site has to communicate with the Miri Airport control tower daily to get clearance before any works can commence.
“Before 5.30am every day, we have to communicate with the airport control tower again to inform them that we have cleared all machinery from site, indicating the flight path is clear,” explained Ting.
Works on the Miri Airport Interchange started in December last year and is expected to be completed by the end of this year. There is a total of 17 spans involved in the interchange.
“Once the six spans are completed, then we do not have to work night shift anymore as we are moving our works further away from the flight path.
“By then we can concentrate on the other remaining works. These activities can happen during the day time and even stretch into the night to quickly complete the construction of this interchange,” said Ting.
