The Technology of Retrofitting Renovation Against Collapsing Building ~ Kwentology

Many buildings were been affected by the earthquake in Visayas. Some experts says, damages can't be avoided by old buildings such as churches of centuries. Mostly, because its foundation is made out only of stones. If only retrofitted or stabilized with steel, damages were possibly prevented or reduced. But, even the new buildings were also affected by the tremor. It should be check first before allowing people entering the damage property.

What we have to do now is to analyze the fault line in the country. To glean a plan before constructing a building. Always ready, write down important tips to stay safe during an earthquake. We have seen the damage and injuries caused by the earthquake in Bohol and Cebu. What is retrofitting? And what contribution could it bring on those old structures?

What is Retrofitting?

To strengthen the structure, this can be subject for retrofitting. In this way, we can immediately prevent attrition cause of an earthquake. Due to the earthquake that occurred in Cebu and Bohol. We often hear the term retrofitting.

Let's find out by means of a structure such as Quirino Grandstand, located near our favorite sight—Luneta or Rizal Park. Before PNoy sworn, the grandstand was overlaid with carbon fiber—the ceiling and foundation of the grandstand from its columns up to beams. A precaution against earthquakes. This process is called retrofitting, an introduction of new technologies to strengthen a structure. - SONA Bam Alegre

Retrofitted Quirino Grandstand

  • The Quirino Grandstand was built in 1939. Over that time it witnesses much history.
  • Quirino Grandstand is a historic place in Manila City. People can't forget when Pope John Paul II visited here in 1995.
  • January 2010, when the Department of Public Works and Highways (DPWH) found out that it is possible to collapse in the event of an earthquake.
  • It's also where President Benigno 'Noynoy' Aquino III made his inauguration last 2010. Then, retrofitting was applied.

It was subjected in retrofitting. Thus, it guaranteed durable for the succeeding 15 years. In evaluation of an architect trained for building technology. The Quirino Grandstand is strong enough, yet stable that can recede against tremulous movements. For the carbon fiber is lightweight but a durable material. Good thing about retrofitted buildings, you don't even notice the changes made on the structure.

Issuance of Building Permissions

Continual updates were made to the implementing rules and regulation of the DPWH. One of the fundamental basis to allow and provide building permits on new building or bridge construction. If everyone follows building code, it can stand the test of time from 30 up to 50 years or more. As long as there is no earthquake or disaster that may impair its structural integrity. These are buildings that undergone retrofitting.

The Importance of Retrofitting

It's really important to pay attention retrofitting old buildings. Preserving its historical value. Especially in Metro Manila, where thousands of people could be killed or millions will possibly be injured if Intensity 7.5 or higher hit the cities.

Retrofitting technology continue to progress and used in countries prone to earthquakes such as America and Japan. It is some kind expensive but, let's keep up with the time. Unlike the storm, we don't have ways to predict earthquakes. So, it's better to be safe than sorry.
