Maccaferri Philippines recently introduced a cost-effective, durable and efficient Terramesh system into a Bridge construction work close to Calamba City.
Calamba City is on the southern end of Laguna de Bay in Laguna Province and lies on the northern slopes of Mount Makiling, a dormant volcano. It is the southern terminus of the South Luzon Expressway and is considered to be a gateway to the southern provinces of Luzon. As a result, it has become an industrial development area with some industrial parks and Special Economic Zones.
In 2015, the city government, as part of its road improvement scheme, planned the construction of Banaderos Bridge. Maccaferri Philippines were approached by a client to assist designing the bridge approaches.
The brief from Calamba City Government determined the need for an aesthetically pleasing, structurally sound and cost effective solution. Our design engineers organized a series of site visits and worked closely with the Local Government Unit (LGU). The suggested solution for the project was a Terramesh structure.
Local contractors took on the construction of the bridge piers, buttresses, and span all of which were constructed in situ out of reinforced concrete. Once these works had been completed the contractor commenced the construction of the bridge approaches using Maccaferri’s Terramesh System. The project was completed at the end of 2015, and the bridge has been in operation for some months already.
Unlike the bridge structure itself, the contractors needed no formwork or specialized equipment to construct the approaches. Thus construction was fast and easy allowing timely completion of the project. Furthermore, the installing contractor found our technical support and installation advice most helpful. The result was considered to be aesthetically pleasing without the need for wall finishing.
The excavation works for the bridge approaches were minimal; significantly less than those required for a more traditional concrete structure. Furthermore, the Terramesh unit offers high seismic load resistance making it ideal for structures designed to be built onto areas with a poor soil quality.
The project ultimately successfully exemplifies how Maccaferri’s Terramesh system can work together with other engineering systems to provide a cost-efficient and sustainable solution.
