Those who talk cock knew very little on how construction works. For info, whenever there is a development, there is major destruction of the environment that most couldn't see or even bother to do so.

Know how to destroy environment then compensate a bit lor.... Its for the future. Else when all your surroundings like are all processed wood, zincs or concrete structure only.

So you must be an expert in the construction industry ?

No, at least much more knowledgeable.

Building with plant is hard to maintain.

Destroying nature with with excavators is way easier but constructing a modern, high rise building is way harder as well.

Didn't see construction halted also?

Ok since you have more knowledge, please share with us here on how the construction industry has resolve the problems with rooting system ?

If you ask me, basically nothing.

Reasons of root damage is pretty simple - planting heavy trees with powerful rooting system but do not have the space for growth or the reinforced concrete to withstand the load was insufficient to begin with.

Once concrete cracks under roots and water sip into the concrete structure, the steel bars inside will rust, the structure is no longer safe as the fundamental strength of the concrete is compromised.

The cracks caused by the plants no need to be big crack, even microscopic cracks are enough for water to sip through and ruin the concrete over time. hmm.gif

If every concrete cracks so easily, most elevated roads are in grave danger now.

The keyword is always design, then workmanship....

Do they plant many trees on the elevated roads though?  blush.gif

Concrete's main witness is the steel bars inside must be protected against moisture and water, moisture and water will cause the steel bars to rust, rusted steel bars will expand and crack the cement, hence the concrete structure is compromised.

Architect is not botanist, they knew little of the plants that they will put there, most probably the developer will chose nice looking plant without in depth knowledge of the plant. Since planting on concrete structure is a new trend, there will be lots of mistakes these expert "architect" will learn over the years, so be ready to become the lab rats of planted building... console.gif

Dynamic loads (i.e. loads that are constantly changing and) are actually way detrimental on reinforced concrete than any tree roots induced pressure. Swimming pools, although do not have dynamic loads, are exposed sun and water pressure that is more immense than moisture from earth. Nevertheless, with proper design consideration and safety factor, effects can be reduced to insignificant.

That is why design consideration is important when it comes to trees. Not sure about other countries, but Malaysia always skimp or overlook on the rc design when it comes to planting trees. In example, common in residential condos to have 600mm depth structure for earth and trees (which imo isn't enough for bigger trees). Concrete's main purpose is to resist compression, while rebars for tension. Both of these elements work together, any lacking of either both will cause cracks due to tension or compression 'failure'. With proper design and workmanship, concrete can be watertight and movement resistant - but that also depends on the whole structure movement as well, as highrises have movements.

Landscape architect is do actually help in trees rooting issue (i.e giving info on each tree's so-called maximum weight and root length for S.O's and structural engineer design consideration). Having plants in structures actually had been encouraged and practiced here over a decade ago, its only the requirement of landscape experts that is quite new....

What still surprises me is that reinforced concrete structure was said not to able to withstand the power of tree roots, which could spell out design error. Also botanist may know how to maintain a plant on normal ground, not necessarily on space tight structures.

Hence anyone who bought such prop is lab rats.

Design can be perfect on paper, but only real world feed back after decades will show the design flaws. By then, it's the owner of the structure that will pay the price for the futuristic design.

Cars also like that ma... lucky ones get a working Tesla, unlucky ones get a kamikaze Tesla lor.... In the end everything that we buy also is a chance game...

But still, buildings with green are better than nothing, considering the damage we did to the environment everytime there are new development.
