Good day contractors n engineers in the house when you take carpenter for roofing work. is it best to pay daily (asin daily pay) or negotiate a contract sum or negotiate the contract days?

michlins:
it's very much possible. He will lure him in with 40 bags first and when he's in, he will then start with extra twenty bags then fifteen and few more ten bags and so on.

Things are really hard and people are finding devious means to get jobs

wow na so una dey do am now?? I just believe the person would cash 1½" of concrete or maybe 2" and it would suffice

Story time... so today I went somewhere to measure the sqm of a compound floor for a stamp floor job after measuring we got a total of 200sqm I told the guy that at 3" of concrete we would use about 100 bags, he shouted and said someone else already told him 40 bags would do the job for regular concrete flooring. how is this even possible? 1" thickness?

FEGEITOK:


I use this ratio as my minimum ratio and every time I do the workers marvel at how much granite I am using. They complain that they are not used to that much granite being used.

I have used both 1/2-inch granite and 3/4-inch granite.

In fact, I was once called Julius Berger for my insistence on the quality of concrete mix.

Once when someone had cause to break a portion of the concrete the workman shouted, do you want to build an everlasting house? This concrete is too strong!

I wash the granite that I use to create a 4'/6"water barrier, but I have never washed the granite that I use for the concrete mixtures.

Going forward, I will.

I even use reinforcement (TMT) for the concrete floors which the laborers said is a very rare event.

are u the landlord of the building or the engineer?

hello house please does anyone have an idea how many blocks would a 10 Tyre tipper of sand be able to mould ?

ANSWER FOUND:

1 trip of the regular 6 Tyre tipper moulds about 11 bags of cement. at 40 units 5" blocks per bag a trip would give u 440 blocks.

Good day house. I made this thread for the step by step process of doing a precast parapet also known as concrete facial board. using a 3 step design.

gandkiss:


Thanks.
1pan of cement
3 pans of sharp sand and
4 pans of granite.?

1 bag cement

6 pans sharpsand

8 pans granite

So after hanging them completely  which took 2 days per building  for that, we then started  pouring with concrete,  the pouring  would  be done in 2 to 3 days not because  of the volume  but because  the pre cast  can't  hold all the weight  at once so we cash 1/3 of the volume to 1st cover the top rod we exposed  earlier  then a day after  we cast 2/3 of the precast volume  and eventually on day 3 we cast the remaining  using a fine mix. Also it's important  not to forget putting a U shaped quarter rod on the beam when casting for roofing  purpose.

how do u guys work ur sqm for a building? normal length x width?

MRFIXER001:
Mix ratios are decided based upon the type of construction structures and mix designs by the structural engineer.
And it's categorized into three which are;
A. Nominal Concrete Mix Ratios
B. Standard Mixes Ratio
C. High Strength Concrete Mix Ratio

Mixing ratio depends on the load and compressive strength of the concrete.

In conclusion 1:2:4 means 1 unit of cement, 2 unit of sand 4 units of granite. And it's advisable to use that. Anything more reduce the compressive strength of the concrete

wow it's funny that this weird mix ratio of mine is a norm here ... I'm learning.

Aforxzy:
The ratio of your concrete mix determines the strength, workability and durability of your concrete structure. The strength is gotten from granite , that's why more granite is used in the mix while the binder is the cement.

Often times you see people using less of the granite because they want a fine finish and they end up compromising on the strength. Also site labour reduce the quantity of granite because it makes the mix heavier for them to carry.

So your workmen are invariably reducing the strength of your concrete element with that mix ratio and it has nothing to do with your location.

A finely finished concrete is gotten from properly mixing the components, vibrating to remove voids and using a good formwork and not by reducing the granite quantity.

However the granite should be washed and free from dirts and clay.

It's your project , insist on the right mix and they will comply.

I doubt u are female tho ahhh... Na man u be boss. thanks alot.

Hello house I'm having a little confusion as to mix ratio. in delta state most concrete are mixed at 1 bag of cement 7/8 pans of sand n 7/8 pans of granite. which is a 1:4:4 mix. and it's a norm. someone here once told me a mix shouldn't be more than 1:2:4. which is 1 bag of cement 4 pans of sand n 8pans of granite. is there any reason why the difference?

Next phase was to allow the precast dry in 2days and then we hang them on our  already half casted beam.  this phase we got extra 12 quarter rods to be used in hanging the casted facial boards. see a short attached video  for a description of the process.
this hanging took 2 people 4days per building

I’m talking about art work for windows, columns and edges.

do the precast. but give it to capable hands

Miyachi:
Please I'm looking for a solution to water ingress in the walls of this property. I don't know the right way of going about correcting this problem. The plaster and paint is flaking off, could this be as a result of low-quality mortar being used? There is also an open flower bed around the building.

is the area waterlogged?

hello house would a 12mm rod be enough for a concrete slab for gutter. the slab should be able to carry a tipper comfortably

damkanlinsin:
Good evening please house I want to do art work on my project. I’m stuck in making a decision about pre cast art work and direct art work. Please which one is best to go for. Thanks

when u say "art work" are you referring to concrete facial board AKA PARAPET? which can either be precast or full cast

thatthickgurl:
Can anyone recommend a reliable and trustworthy contractor please?

Preferably someone with the fear of God.

contractor or engineer?
