Today the missing rebar was purchased this morning.
Lack of luck, the delivery truck is not available until January 30th. One week delay! :oops:
2 people from the team took the pick-up and spent the day transporting 80 bars in 2 trips (100 kms per trip) :roll:
The last 20 bars will be transported later :|

Resume work tomorrow morning ... (well, maybe ... :mrgreen: )

Breizh29:
The structural steelwork is really impressive. I suppose that the given soil compactness has asked for that. And that perhaps presents the biggest portion of the total building costs.

I think that not everywhere here in Thailand is such a soil. When somebody starts to think about having a swimming pool in his garden, the enormous cost of the steelwork may discourage him from the idea. In case of my swimming pool the soil is obviously on the opposite range of the compactness, so I do not have any of such bars, appart of 5mm steel wire laid under every 2nd layer of double Cinder block walls. In fact, I did not test the soil, neither thought much about that, just had decided to do it so easy.

So, for the ones who are afraid of high building cost and would get courage enough to make it easy (in his own management, just with few hired workers), my older thread here about affordable swimming pool could be of some help. It did not cost over 150,000 Baht, the only specialists who never saw a swimming pool were there a group of village bricklayers. All materials (cement, tiles) were bought the cheapest one in the village construction shop. Pump, filter, PVC piping from GH, installed by an all-round chang under my assistance.

The swimming pool has been now over 10 years in daily operation, had overcome 2 earthquake in area, one of them last year, and one some 6 years ago (from the epicentre 70 km) when ceiling lamps were swinging and the water in the pool was flowing in a wave over the edge (also in water tanks and fish pond similarly built above the ground).

I do not insist that that is the best construction way for a swimming pool, nor advising to do it exactly so. However, it can give an idea for consideration to the ones who want to swim every day and cannot spend big money (and the wife just asking for a new diamond ring). And of course the soil is compact enough.

For additional info - what cannot be found in my thread viewtopic.php?f=19&t=4736 - I am ready to further explain.

Hello Klondyke,

I saw your thread on your pool. And of course congratulations for having done so by spending so little money. :wink:
But I think that on our field (rice field backfilled and ground water table close enough to the ground) this type of construction was not possible. And that's why piles were put under the pool. Three contractors were solicited for the pool and they agreed on the method to use for the initial foundations. So I hope it will go!
For reinforcing bars: 300 bars, length of 10 meters (12mm twisted) with a unit cost of 164 baht.
Workers have now begun the second level of rebar on the walls.
The filling of the concrete for the slab is planned for thursday but I don't believe too much! :roll:

The work resumed. The double reinforcement of the over-elevated basin is finished. The rubber seal has been inserted between the two rows at the bottom of the wall. :)

The second row of rebar has also advanced well in the main basin.

I had a doubt about the pouring of the concrete in the slab planned for the day after tomorrow but I think it is now possible! :wink:

Because of a bad organization of work, the pouring of the slab didn't take place today. :(
It will be tomorrow morning if no other bad surprise! 3 rear-discharge concrete trucks are therefore expected.

2 workers have worked today on the spa.

Hi evryone,

Surprise at the end of the morning, arrival of 3 concrete trucks and filling of the concrete in the walls of the main pool. :D I didn't think it was going to happen today.
The pipes for lighting the 3 LEDs were installed through the formwork and pieces of rebar were sealed in the wall will serve as support for the gutter. :wink:

I will have to watch now very seriously the construction of the top of the wall (arase?) and its flatness! :lol:

The formwork was removed yesterday. They started the top of the wall (arase), I don't understand their method and it stresses me!
I shall certainly have to change the curbs to have a nice overflow around the pool. As a result the additional stone slabs will be used for the beach.
For the spa no change.

The mosaics were chosen (Kera Tiles):

Weber products will be used for tiles: Tile adhesive and Tile grout. I have to check if Epoxy should be used.

"Fitting" of walls finished.

The workers have almost finished finishing the excavation of the buffer tank under a bright sun and by a heat which becomes strong again in the afternoon (35 ° C).
The excavation is about 3m X 2m40 X 1,60m. The volume of the tank will be approximately 8m³. The technical room will be located above the buffer tank.

@Breizhu,
My experience with the buffer (overflow) tank:

My tank is 2x2m, H=1, using the space under the stairs into the pool. And throughout the year, the water level is there only some 20 - 40 cm high, the pool is 55,000 m3, 12x3m. Even during swimming of 2 - 3 people there is no visible rise of the water level in the tank, even when the pump is not running (not sure how it would be when an elephant jumps in).

I do not advise you to change the size of your tank. This is to know just for somebody, who decides for or against the overflow pool. Sometimes it is argued that the OF pools are too expensive because of the necessity of quite large OF tank.

In fact, the pool selling companies like to argue that way. Reason? They want to sell their plastic foils and with the foils the OF edge is not so easy to make. And consequently, the pool without OF (but with skimmer) have the walls some 20 cm higher above water level - higher (or deeper) than the OF pools, so they sell more of the foils.

At the OF tank there is one important thing to think of: to have a simple OF water outlet from the tank when suddenly overfilled by a heavy rain water coming from the pool - filling fast the OF tank in the ratio of surfaces of the pool and OF tank.

And the OF tank should get an easy access and opening for cleaning of the dirt collected at the bottom And nearby a hose with a good water pressure for spraying. After some 2 - 3 months it is needed, even if you have a good catching of the leaves at the inlet into the tank (what is often forgotten). Then you will appreciate when the tank bottom have a good slope and at the lowest corner a spot 20x20cm with few cm deeper for placing a submersible pump for easy disposal of all the dirt.

Thanks Klondyke.
I know some people have a small tank and that is usually enough. But the rule seems to be 10% of the pool water volume so I do so!
For water outlet from the tank I will of course ensure that they don't forget it!
Please what kind of catching of the leaves at the inlet into the thank have you installed?

Reinforcement of the buffer tank completed. Then as usual installation of the inner formwork, this time the outer formwork is the edge of the excavation.
Image

Granito slabs that will be installed on the base for overflow in the peripheral gutter of the basin.
