Loud explosion rocks Serendra

[siopaonatoasted]

An uso ngayun sa prefab, bolt on sa frame yung mga walls. So yung wall ay parang cement na binuhos sa wire mesh ( we do not know kung ilang mm ang diameter ng wire mesh), then kapag dry na bolt on sya sa structure ng building.

Casualty update. Six dead. Three bodies were recovered from Room 501 in Serendra 2. Unknown whether they died from the explosion or were already dead ...

NDRRMC: Six dead, five injured in Serendra condo explosion
June 1, 2013 8:40am

The National Disaster Risk Reduction and Management Council (NDRRMC) on Saturday said there are now six people dead from the powerful explosion the previous night at a residential unit of the Two Serendra condominium at Global City in Taguig.

Initial reports on Friday indicated that the powerful explosion that hit the posh Bonifacio Global City in Taguig City on Friday night killed three people from a passing delivery van who were crushed by debris.

On its 8:00 a.m. report on Saturday, the NDRRMC said there were three other male fatalities from Serendra's Room 501 where the explosion is believed to have occurred.

The NDRRMC also said at least five people were injured: two males, two females, and a nine-year-old child who were passengers of a passing Hyundai van.

Please excuse my ignorance, pero cheaper option ba sa construction ang prefab? I would not expect that from a luxury condo building?

[_Cathy_]

diba prefab parang puzzle lang yan na dugtong dugtong lang? as of the moment pinapanood ko itong tnatayong warehouse sa tapat namin. ang bilis matayo gamit mga prefab ata. wala naman akong napansing nagweld. o di ko lang nakita?

Yung house ng neighbor namin took more than 2 years to build, sinubaybayan ko ang pag gawa, yung hukay kasing lalim ng bahay!!! Nakakatakot nga e :nervous: May nadaanan naman ako na duplex parang it took less than a year to build at hindi ko napansin na hinukay ng malalim. Hindi kaya prefab din yun kasi developer lang ang gumawa?

It is cheaper because you can have the prefab structures build off-site in a factory then transported to the construction site as needed. It saves time on the construction itself. So if you cut down construction time by 10%, you save on all the stuff related to construction like labor, heavy equipment operation and rental, etc.

Prefab parts also make it easier to build structures because many walls are identical. Just like putting together a LEGO model.

Time is money.

Wow I never expected that type of shortcut from Ayala.

We have a condo project nearby our office. It just finished. We kinda noticed the progress was quick because after they constructed the building's frame structure, the walls and floors seemed to be prefabricated pieces. The slow portion of the construction was the condo's foundation & basement.

Wow I never expected that type of shortcut from Ayala.

it is not a short-cut... it is a standard practice in construction. The resulting structure is as strong (or even stronger) than conventional construction. Stronger because it is generally lighter with an internal framework as compared to traditional structures which are basically platforms on pillars. In a quake, a traditional structure can shake and fall flat on itself. Prefab will ride the quake and can survive relatively undamaged.

Is that how buildings were done in the past even during the 80s (or older). What is it that they call buhos? As I understand buhos is more expensive?

Yes it is cheaper,di naman sacrificed ang structure ng condo even prefab yung walls, kasi ang importante sa highrise, kaya isupport ng foundation mo yung load ng buong building. And of course, prefab is lighter compared na gamitan mo yan ng traditional CHB.

Buhos ay yung sa floor ng 2nd, 3rd, 4th floors.. etc.. Meron pa ring ganyan ngayun, pero steel matting na ang gamit, hindi yung inaasa lahat ng load nung slab sa steel bars.

Yung dingding sa traditional construction, of course CHB.

"buhos" is the platforms on pillars. Standard construction for 80s to current. Issues with this is the need for continuous supply of concrete. If concrete flow stops too long, it can create a layer of weakness that can cause the building to collapse. Aside from this, the size and number of pillars are critical (as well as the pillar ends to prevent "punch-through"failure). If a SINGLE pillar fails, this can cause the entire floor to fail. In turn, this can cause the entire building to collapse.

What is CHB?

[siopaonatoasted]

AY nakalimutan ko, buhos rin pala ang tawag sa tagalog nung sa mga poste, I beam na ngayun ang uso.

Kapag buhos, typical ata concrete footing ang foundation, yung typical sa condo due to confined space and sa taas, lahat pile driving, not so sure kung pwede sa condo yung micro piles.

[_Cathy_]

Naririnig ko kasi parati sa matatanda kung buhos ba yung pagkakagawa. I formed the impression na pag buhos it's expensive and sturdy. Saka pag malalim ang hukay,

For houses, "buhos" is a nice way to create a solid single piece box for the structure. Since homes are usually two or three floors maximum, prefab construction techniques may not be chosen.

As for the "malalim na hukay", it depends on the land and bedrock depth. If bedrock is relatively shallow, you don't need to dig very deep to find a solid base. But for others with soft ground and deeper bedrock, piles might be needed to stabilize a house.

Were there other cars that were damaged during the explosion? How can that be claimed with the insurance?

Wow mali...

NDRRMC does a double-take: Three, not six people killed in Serendra blast
June 1, 2013 8:40am

The National Disaster Risk Reduction and Management Council (NDRRMC) on Saturday issued a morning report saying there were now six people dead from the powerful explosion the previous night at a residential unit of the Two Serendra condominium at Global City in Taguig.

However, a radio reporter said NDRRMC took back its statement and clarified that only three people were injured in the blast.

Initial reports on Friday indicated that the powerful explosion that hit the posh Bonifacio Global City in Taguig City on Friday night killed three people from a passing delivery van who were crushed by debris.

On its 8:00 a.m. report on Saturday, the NDRRMC said there were three other male fatalities from Serendra's Room 501 where the explosion is believed to have occurred.

Radio dzBB reporter Allan Gatus on Saturday on Twitter said NDRRMC stated that only three people were killed in the blast.

I read in the news that the unit where the explosion occurred was unoccupied.

Mas nakakatakot ito.

[_Cathy_]

They still don't know the cause of explosion up until now. The tenants were already transferred to hotels but how long will it take before they could go back home. Parang nakakatakot na rin. This is not good for Ayala. Bakit nga ba puro pagsabog ang issue nila.
