TCGI draws its strength from the experience of more than 28 years of providing comprehensive engineering services to the transport sector, particularly with respect to planning, design and construction management of all types of projects ranging from urban expressways to rural highways, feeder roads and bridges, private industrial pier facilities and municipal ports and airport facilities, among others.

 

Grade Separation
Edsa Ortigas Avenue InterTRANSPORT

The grade separation at Edsa/Ortigas Avenue intersection is a multi-level, highly directional interchange consisting of two similar left turning ramps from Edsa to Ortigas Avenue. This P344M superstructure stands as one of the marvels of Filipino engineering technology. Set on a major intersection of Epifanio delos Santos avenue or Edsa, Metro Manila’s busiest and most important thorough fare and considered as the spine of the metropolis’ road network, the interchange “flies over: the area and provides convenient access to an estimated 54,000 vehicles per day.

In July, 1989, TCGI Engineers was commissioned to review, study and assess the existing condition of Edsa/Ortigas Avenue Intersection, and to propose improvement schemes to increase its capacity. The interchange scheme was recommended after seven months of data gathering, field surveys, planning, public hearings and coordination meetings. The detailed design of this project took 14 months of engineering and tendering activities ending March 1991, when the construction was started.

Construction Supervision was awarded to TCGI Engineers as Consultant and Engineering.
 

Parañaque-Sucat Road Widening & Kalayaan Avenue Extension

The project involved the design of the widening of the existing two-lane Parañaque-Sucat Road to a six-lane divided highway with a 9km stretch and a 30m right of way. The detailed engineering design covered the geometric design, channelization at grade on major intersections, two new bridges, underground drainage system, lighting facilities, parcellary surveys, pavement markings and road signs.

The project also included the design of the Katipunan Avenue Extension in Quezon City. The design included geometric design, underground drainage systems, lighting facilities, pavement markings and road signs, new 18.64m RCDG bridge, and parcellary surveys.
 

Mindanao Roads Improvement Projects

The project includes rehabilitation and new construction of the 89.5 km., 7-meter wide Molave Oroquieta Road using Asphalt and Portland Cement concrete surfacing with 1.0 to 2.0 meters gravel and asphalt shoulders. Eight existing Reinforced Concrete Deck Girder (RCDG)bridges were replaced with new bridge structures and 35 box culverts were constructed. A steel truss bridge was also replaced with a pre-stressed girder bridge.

The 18.8 km. Pagadian Tucuran road was paved with Asphalt and Portland Cement Concrete Pavement (PCCP) at urban centers with 1.0 to 2.0 meter wide gravel shoulders.

TCGI Engineers provided construction supervision services.
 

Circumferential Road 5 (Package A)

Together with Japan Overseas Consultants, TCGI Engineers undertook the detailed engineering design and construction supervision services.

This project was designed to provide the missing links between Aurora boulevard and Imelda Avenue and EDSA to Pasig-Pateros Road, and included the construction of a 220m. bridge across the Pasig River. The circumferential road (C-5) is a six-lane divided highway while the radial road (R-4) is a four-lane divided road with a total length of 5.49 km.
 

Philippine Assistance Program Support Project

TCGI Engineers, as sub-consultant of Willbur Smith Associates (WSA), provides technical services to USAID and sponsoring agencies designated by the Philippine Government to prepare area development plans, engineering master plans and construction design, feasibility studies, environmental analysis, physical surveys, market analysis, land use plans, and other studies related to project proposal for potential funding under the PAP.

TCGI expertise has been a vital input to various major nationwide infrastructure investment that include industrial zones, agro-industrial processing facilities, fishports, seaports, airports, roads, power, telecommunications, water and waste facilities. The Firm's involvement in some of these programs is reflected in the following projects.

General Santos City Airservices Upgrading project TCGI provided technical expertise to support the WSA airport planning and engineering team. Manila Grains Terminal Project aside from providing policy and technical guidance, TCGI served as the liaison agency between the WSA project team and the Philippine Ports Authority.

Manila Bulk Terminal Project TCGI assisted WSA in the planning and engineering studies of this seaport and harbor project.
 

Semirara Pier Facilities

The Semirara pier, used to load coal via mine-to-ship conveyor system, features a 1200-meter causeway, a 15 m. wide x 283 m. platform, and a 166-ton rail-mounted ship-loader on the deck. The structure is supported by 370 cu. m. concrete filled pipe piles of 600 mm. diameter, 12 mm. thick and 42 meters average length.

The deck, which is pre-cast post tensioned T-beam with 100 mm. cast-in-place concrete topping, was designed for 80-ton trucks.

TCGI Engineers undertook the planning, design and construction management.
