LRT LINE 1 CAPACITY EXPANSION
Sumitomo-Itocho Joint Venture (SIJV) was commissioned by Light Rail Transit Authority (LRTA) to design and construct the LRT Line 1 Capacity Expansion (Capex) Project Phase 2 (Package A). The main objective is to obtain a maximum of 40,000 PPHPD (passenger per hour per direction) likewise support train operations with a minimum headway of 112 seconds.

Provisions were also made to accommodate passenger transfers from and to Line 3 (Metro Rail) and LRT Line 2 in addition to upgrading and improving relevant facilities of the system.

The LRT Edsa Station includes the construction of new North East and North West Passenger Handling Area (PHA), which is a typical 2 storey structure with mezzanine and roof deck with a base plan of 28.22 x 11.0 meters and 12.9 x 15.0 meters respectively. Renovations were also done for the existing South East and South West PHA’s.

The Doreteo Jose Station includes the renovation and expansion of East & West Passenger Handling Area (PHA). The station also featured an overhead cross-over walkway bridge connecting east and west PHA’s to relieve the pedestrian traffic at the sidewalk level.

The Monumento Station includes the renovation and expansion of West Passenger Handling Area (PHA). The West PHA featured additional ticket booths at the platform level supported by columns and isolated cantilever footing. A new structure that will serve as signalling room along the northbound lane adjacent to the existing telecom room was constructed.

The project also includes the design of the Overhead Catenary System (OCS), Operation and Control Center Building, Workshop and Warehouse Extension, Light Maintenance Hall and Pit Extension Area.

ACO performed structural engineering design and technical support services during construction for the project under the Sumitomo-Itocho Joint Venture (SIJV).

NAIA 2 TAXIWAY REPAIR AND UPGRADING
The project involves the Repair and Upgrading of Taxiway Charlie-6 (C-6) and Hotel-2 (H-2) Segment of Taxiway 06/24 located at the Ninoy Aquino International Airport (NAIA) Complex in Pasay City, Metro Manila.

The project is part of the mandate of Manilla International Airport Authority (MIAA) for the improvement and maintenance of all facilities of the Ninoy Aquino International Airport (NAIA) to ensure its continual, reliable, efficient, and safe operations on a 24/7 basis.

The works were executed while the NAIA remains operational throughout the period of construction and all works were executed, completed and maintained without causing any interruption to on-going NAIA operation.

ACO, under PhilJAC Inc., performed the detailed engineering design for the project.

NLEX BRIDGE REHABILITATION
The project involves the rehabilitation of 4 overpasses spanning across the North Luzon Expressway that is operated by Manila North Tollways Corporation (MNTC). The overpasses include:
  • Lias Overpass – a 2 span, 2 lane bridges constructed using cast in place concrete deck on structural steel girders with reinforced concrete substructures.
  • Taal Overpass – a 2 span, 2 lane bridges constructed using cast in place concrete deck on structural steel girders with reinforced concrete substructures.
  • Tabe II Overpass – a 4 span, 2 lane bridge constructed with a reinforced concrete deck and girders, and substructure.
  • Duhat Overpass – a 2 span, 2 lane bridges constructed using cast in place concrete deck on structural steel girders with reinforced concrete substructures.

Repair and strengthening of the existing damaged concrete deck slabs and substructures were performed by applying epoxy pressure injection and carbon fiber-reinforced polymer. It also includes the installation of restrainers and tie rods as part of the seismic upgrading of the bridges.

ACO Performed the detailed assessment and detailed engineering design for the rehabilitation project.
