Day four..
Casting of the foundation footings
These footings have two type
1. Strip footings
2. Isolated pad footings

The strip footings are 675mm (3 times the width of foundation block wall) and 225mm thick.

The total perimeter of the foundation is about 200m removing the column bases we leave us with about 145m

Volume of strip footings = 145x0.675x 0.225 = 22cubic meters.
Using a mix ratio of 1:2:4 by weight, we have about 6.25bags of cement per cubic meters = 6.25x22 =137bags (giving an allowance of 20% for wastage, occasionally wider strip footings) = 1.25x137 = 165bags.

For the column base : we have about 36 x1.1x1.1x0.45=
20cubic meters + 2.2x1.1x0.45x2 = 2cubic meters
We have a total of 22cubic meters = 165bags of cement.

Total calculated value required = 330bags of cement

completion of casting work...
summary of materials used so far (note the client have a relative on ground that supply all the materials we need)
as a matter of fact we have many external supervisor coming in to check our job.

cement = 235 bags so far ( blinding, isolated footings and combined pad footings)
gravel = we cant really tell now
sand = will come back with this later.

laying of foundation column : according to my estimate, we will need about >=2500blocks for this foundation and since one bag of cement will lay between 40 to 50 blocks, we have = 2500/40 or 50 = 63 bags or 50 bags

More updates from the block work

More from block work

We are almost through with the block work, there are extension that we have to make. Some group of my workers are already warming up for the sand filling and compaction of the foundation.

The client is lucky that we have sand fill already on site from the debris of the demolished house and the existing dpc of the previous house.
Filling operation should take two days while compaction will take one day

I love this, very good work as usual. Keep doing it good as we are enjoying the project. Welcome to Enugu my man.

from this building line the other two corners of the building are set out using " 3 4 5 " right angle triangle method . in this case, we use multiple of this triangle (12, 16, 25).
these two other points were located and the profile was nailed after offset from these original four points

Bros,congrats. Can you give me the roofing aspect of the house? Am based in your sister state.
See my signature....
Thank you..

Congrats and Weldone bro.

We still dey follow and looking for updates o.

Rounding up foundation block work and filling

More updates from our ongoing job

abdulwastecx:
check out this our combine footing....at harney project will follow the structure design to the later because i can hardly sleep if work are not done properly

This is over reinforced,
No need for top bars when you not going that far into the ground.

Since you are not the design engineer. .. . I don't think it is over reinforced.

Combine footings behave like a continuous beam and during the analysis you have both hogging and sagging moment which translates into a top reinforcement and bottom reinforcement

Going far into ground depend on the location of strata where you have the required Geotechnical properties used for the design (bearing capacity). It has nothing to do with how you reinforced your footings

More filling and compaction work going on

We mobilized to site last week Monday, making it 10days now.

Preparing for our waste plumbing pipe.

The client has decided that he want surface piping because of Maintenance, he is of the option that conduit waste pose lot of repair challenges

Okay na...we dey wait for the pictures.

Apart from the aesthetics, is there any advantage of conduit piping over surface piping for plumbing?

Servicing.
Wires can easily be pulled out and replaced when the need arises.

@op Are u the one that made the structural & architectural drawings ?

For this job no. The architectural and structural drawings were done by a different consultancy film.

Cost is another advantage, it cost more to conseal surface plumbing pipes because of extra money for vent.
