HDB Supposed to Last for 99years But It is Almost Not Fit for Living after 40yrs

This was told to my by some old bird. apparently a lot of the older public works (a good eg is HDB) were not built to standards. Reason being that inspectors who signed off on it were "encouraged" to do so by "friendly influence". It is suggested that the contractors who were working on it were not happy enough with how rich they were and wanted to eke out even more money.

Sad to say, but it looks like you can take the Chinese out of China, but you can't take the China out of the Chinese. :frown:
i posted somewhere in a thread that during construction in the 60s and 70s contractors used wooden poles with bamboo strips to erect “scaffolding” up to 10 storeys high, and vertical and horizontal alignments of some blocks were off and crooked. they also relied on samsui women and jiuhu laborers who anyhow humtum mixture of concrete like frying char kway teow - scoops of sand here, scoops of cement there, scoops of aggregate or gravel here, there, everywhere - poured buckets of water and stir fried by hand in a makeshift pit and loaded onto wheel barrows to be pushed up gangplanks from floor to floor. tools of the samsui women were just changkols and dirt baskets. and they would carry two baskets at a time counter balanced on a bamboo pole. that was the hdb construction standard and best practice then.
 
Boy injured by concrete that fell from ceiling of 45-year-old flat, HDB to carry out repairs
I asked my uncles and aunties to wear helmets when taking shower can?

"With regular maintenance, spalling concrete in HDB flats, if it occurs, is usually minor and can easily be repaired," said the board.

Talk is cheap. How can I make sure that if my flat receives regular maintenance?
Any check list or checking regime? how often we have to ask HDB to come into our flat to check?

That is the plan ...if you still stay in HDB flat after 40 years, then you are a loser. The PAP expects most to move into condo after 40 years. Then the flats can be redeveloped and sell at a higher price. Rejuvenation.
 
They shouldnt make HDB flats using concrete. too dangerous. Concrete drop on your head can cause serious damage.

Should use gypsum drywall.

ceiings and floors cannot handle the weight of family of 6.9 with couple pounding in bed day and night and kids running wild playing soccer indoors. still need 2 by 4’s to secure frames of walls and floors plus hardiebacker cement baseboards to seal and strengthen floors. but that’s usually for a 3-storey home in temperate climate. for sg with highrise homes going up to 69 floors, the building needs i-beams and girders for the frame and reinforced concrete for the floors. can prefab floor panels with strict quality control on composition and types of materials used. no more suka suka humtum here there in the concrete mixture with agak agak amounts of sand, cement, aggregate, gravel, dirt, dust, spit, salt, pepper, soy sauce and sambal. when ceiling concrete spalls, it’s usually at the rebar seams where there’s a lack of fine aggregate and good cement bonding.

your description of humtum concrete is adequately evidenced by the photos in this thread.:geek:

water seepage and absorption by concrete pose another problem to the layer of rebar, which gets rusty and loses bonding to the cement over time. the way the rebar layers are interwoven in the concrete can either provide a 3-dimensional cage or mesh for rebar to hold concrete together even if there’s rust or lead to concrete peeling off as in spalling as rebar layer is only 2-dimensional like meat in a hamburger or lettuce in a sandwich.
 
HDB flats are eligible for home improvement program after 30 years. think 80% of the residents have to vote in favor for it to proceed. don't know the details. i wouldn't want major upgrading program which lasts 1.5 to 2 years with lots of constructions noises and inconveniences. but some lite home improvement program for toilets, windows, pipes, doors etc... ( residents to pay small sum of money ) would be very much welcome.

The other major issue is the use of bricks. In the older HDB flats, they construct the walls by laying brick by brick manually. Then plaster over. For interior walls, this might be ok. But for units facing the exterior (like end units), I have been told that some of the mortar is not binding the bricks anymore. The exposure of the outer walls to sun and rain eventually erodes the outer plaster and damages the mortar. Hence, water leaks through the bricks. I think one good kick and those walls would fall out and the flat dweller will get a free balcony view.
