We will share the floor plan,elevations and 3D views once permission has been given by the client.

Size of land - 324.00 sqm
Total area of building - 88.92 sqm
Total unbuilt area - 235.08 sqm
Percentage of site covered. - 36.4%
Percentage unbuilt - 63.6%

Client - Private individual, nairaland referral
Estimated budget for construction - N5million
PROJECT timeline - 4 months

Mobilization to site and site clearing/grubbing started on Wednesday 30th of March 2016, here are some pictures taken on site. Strip foundation will be used due to the nature of the soil and topology. Settting-out and foundation excavation will start immediately

Foundation excavation work ongoing.

Foundation footing casting ongoing. The depth of the foundation excavation is 18" deep and the land slopes slightly in two directions so the foundation will be stepped accordingly.

The thickness of the foundation footing is 4inches but to ensure a leveled and plumb surface for the foundation blockwork, it varies a bit but just slightly.

Following.

More foundation footing works pictures.

Foundation blockwork setting in progress, the first coach being laid.

Solid blocks & structure

The foundation is finally taking shape and we should be done by evening. We will be doing 4 coaches on the low side and 3 coaches on the high side of the slope.

Materials used for foundation footing and blockwork

1. 550nos 9inch blocks (N140/bags)
2. 20 bags of cement (N1600/bag)
3. 1 trip of 10tons granite (1/2 inch size)
4. 1 trip of 10tons sharp sand
5. 1500 liter of water

We leased the water tank at N500 per day for 3 days and bought 1500 liter of water at N2000.

Foundation work completed. We will start the backfilling immediately.

The carpentary formwork and reinforced iron work for the foundation columns is in progress.

Work has been temporarily stopped due to a dispute between the omo-onile and the client. Safety first for my team and we are waiting for the ALL CLEAR signal.

Work has resumed back on site after negotiations were concluded on issues raised.

The columns have been worked on and casted. We used left-over materials from the foundation footing and only purchased 16mm and 10mm reinforced iron with binding wire.

Back-filling of the foundation pit is also in progress and for this stage we decided to apply the *principle of killing 3 birds with one stone* to achieve one of our major aim for this project, making building cost as minimal as possible without compromise on quality and building standards.

1. Make available backfilling material and cut down on cost of procurement.
2. Make available storage for water and eliminate cost on leasing a water tank.
3. Construct our septic tank and soak-away while achieving the two goals above.

It took a while to convince the client as he wasn't ready to construct the septic tank/soak-away yet based on his cashflow but after carefully analysing the pros and cons and long term benefits, he saw reason and is genuinely glad now.

So far, we have been able to fill 3 pits with just 4ft depth of excavation and we are goin down to 8ft and we haven't dug the soak-away yet.

Following up on this professional details

Nice job, following

Four bays have been filled so far and the soakaway digging has commenced. We estimate we will be able to fill up one more bay with the excavated sand and then we can buy filling sand for the 3 remaining bays.

nice work... pls keep us updated...

Nice one
Following attentively

Blockwork, flooring and plastering for the septic tank has been completed and we can now use the SP to store water for construction purpose. The blockwork for the soakaway is also completed.

The client decided to start the perimeter fence to give more sense of belonging and added security from encroahment. So we stareted with the fence footing excavation today.

The perimeter wall work is ongoing and we are laying just 500 blocks for now. There was a dispute over the land boundary and the surveyor made an error which resulted in having just 4feet setback at the rear instead of the 6feet earmarked.

Approximately how much was it to complete the soak-away/septic tank?

Hi, what is d update? nice job!

Thanks for the compliment, the client is mopping up funds for the german floor and blockwork so we are on temporary hiatus.

msogunro:


Approximately how much was it to complete the soak-away/septic tank?

The total cost approximately are:

9inch block - 500nos @N140 = N70,000
6inch block - 200nos @N130 = N26,000
Iron reinforcement with artisan wage = N40,000
Wood formwork with artisan wage = N20,000
Labour for digging, blockwork, flooring, plastering, casting = N90,000
*Assume sand and granite likely already available from previous work

Hope you find this useful.
