Megawide Construction Corporation reported that its Precast and Construction Solutions (PCS) unit is supplying precast double tee slabs for the North Luzon Expressway’s Candaba Viaduct expansion by working closely with Leighton Asia.

In a statement, Megawide said the project, which involves the construction of an elevated roadway spanning the Candaba swampland between the provinces of Bulacan and Pampanga, is seen to further enhance the efficient flow of traffic within the thoroughfare.

The PCS contract package covers six kilometers of viaduct area, where double tee slabs will be installed to serve as the bridge’s main support.

Double tee slabs are structures resembling the shape of side-by-side capital “T’s” capable of supporting heavy loads with a wide span.

“Double tee slabs are ideal for elevated roads due to their strength and durability in supporting heavy loads from large volumes of vehicles, while meeting the prescribed width,” said Megawide PCS Executive Vice-President Markus Hennig.

He added that, “Furthermore, precast is an ideal alternative for these types of infrastructure projects, which offers faster turn-around times, flexible, light-weight design, and higher levels of standardization.”

The Candaba Viaduct system is Megawide’s first project showcasing precast double tee slabs systems. Production of these formats started last year in time for the project’s commencement within the first half of 2024.

“We are proud to be supplying our very own precast products to Leighton Asia and the NLEX’s Candaba viaduct project. This stretch is a vital piece of infrastructure that will continue to improve connectivity between Metro Manila, Central and Northern Luzon.

“We look forward to serving more developments of these kinds to facilitate intra-regional commerce and mobility, promote increased activity and productivity, and support overall economic growth,” Hennig noted.

As part of its expansion program and as a means to improve logistics and efficiency, PCS will deploy a new mobile precast plant in Northern Luzon that will serve Candaba and other projects in the area.

PCS continues to innovate and augment its precast capabilities for infrastructure and has supplied units to major infrastructure projects using specialized proprietary technologies, such as hollow core in producing pre-stressed slabs with long spans that maintain maximum strength and form liners, which add architectural finish.
