If HDB is using Chinese developer, please read what happened to Bangkok skyscraper. Read liao damn scared

[KakiMeow]

tis one 40 yr ago lo ...

... still track lecord veh good

other pples few year one time ijjit

 

[zoossh]

Most bto projects are china and local joint venture.
So how?

Local will absorb the responsibility

 

[1982-1994]

@1982-1994 chu worry? High floors.

I had experienced tremor in the first year of moving into the current flat
Not to worry,toh then toh loh mybfd

Low floor residents have higher chance of survival though

Har? SG no earthquake one rah!

 

[Fellowes]

Singapore has no earthquake. So, it's easier to get away when developers try to get away with cheap materials, poor workmanship to cut cost.

I hope this never ever happens to a HDB building. If it does, the consequences will be very very serious. Nowadays, our HDB building are much taller than old days. More people will die if buildings collapse.

Hope HDB and BSC do their job properly. They are being paid to ensure everything is in order and to sell us the “lease” of 99 years of the HDB for 6 digits figure so we as buyers expect certain level of professionalism from them and the quality of the building they assign the construction firm to built.

Don’t expect limpeh pay 6 figures still consider: “pay peanuts get monkey” type of HDB flat.

I used to work as a site engineer for a main con company. Yes there are some alibaba, but not to the point of tofu building.
Structurally (meaning concrete, rebar and/or steel structure) there are alot of steps involved to prevent alibaba. For example, during casting of concrete, they will take a few samples of the concrete truck concrete and send it to another company for testing of the compressive strength for 7 14 28 days.

For example for steel structure, there is alot of checks needed before they release the steel structure to onsite. Even after they grout, still have to take the grout for sample.

All these records are given to the rto/re and consultant for record keeping.

Generally, structurally should be ok. I mean i do witness some alibaba but not to a very jialat extent

If not designed to withstand severe earthquake means it will collapse if at epicenter of 7.7, but will still withstand a lower magnitude

When I passed by construction sites, the rebars used in the construction are rusty. Over time these rusty rebars will become brittle, weakening the structure.

Or hdb painted these rebars brown?

Depends on how much the building sway.

Speaking from the perspective of a small time developer… The BCA doesn’t play around. Samples of the foundation pour are taken for strength testing from every project.

Maybe small time developers are discriminated against or held against a different set of standards lol.

Rust is cosmetic. It actually helps the bonding in a pour. Oxidation ceases once encased in concrete.

Stainless steel rebar is available. Nobody sane uses it though.

This is why i avoid tiong developers at all cost...can't be trusted.

No amount of discount is worth the risks

China censorship very good.

It is well known concrete bond better with rusted steel. Alkaline condition in wet concrete and harderned concrete will chemically convert the rust and protect the steel from rusting.

"Never trust always verify". Lol somehow it reminded moi of cybersecurity "zero trust" practice and framework. Guess it shows that some topic can easily be transferable

 

[Hello_Kitty]

how about apartments built on reclaimed land???

 

[mooseolly]

Desmond will create a new cat of HDB liao. Its under Ultra Prime, MOP will be 15 years, whole project guaranteed non Chinese, from Dresign till fixtures and high earthquake resistance. Ultra of course come with a premium price, and must wait longer as non chinese contractors usually slow slow one. Project will be situated on those location with granite underground.

Go buyers for these ultras boh?

How about those built on hill-locks like havelock hillside ?

HDB flat projects the construction contractor is just responsible for building. The architect, structural designer, m&E designer, site inspection, lab testing all by other companies.

Last time the site inspection staff were hdb employees then cut cost outsource to private consultant.

 

[nachtsid.er]

We have bca.

Why is every1 so ignorant here ?

Cos when bbfa mentality is always ad hominem arguments
Never fact based

 

[jeff79]

Even hdb trying cost cutting ways to maximise profits. Jungle land that was at no cost of land acquisition compensation yet charge so high.

I still trust the old construction method, slow but sturdy. Look at those old colonial buildings, almost a 100 years and still standing strong.

Those lego like BTO construction, I suspect some hard shaking will dislodge or break the bolts holding them down. Once the pieces are out of place, we'll see a repeat of the Thai building.

HDB precast structural components are joined using steel rebar splices and cement grout. If the steel rebar splice length designed long enough or mechanically interlock rebar splice can withstand earthquake and no much different from cast in situ.

The collapsed bangkok building was skyscraper core wall design with just 14 pillars around the edges and beamless floor slab. HDB flat is different structural design, using traditional pillar and beam frame design. Even the 40 50 storey tower blocks have many pillars between the core and edges. The household shelters scattered within the hdb building also add structural strength.
