kaze4blues:Good practices so far, you are doing well! ![]() True to that, actual work onsite is like nothing I had in my head at planning stage. Still we build! ![]() I have mentally modified expected completion dates for the project. |

Now we bought 106 pieces which is 8pcs below the 114 pieces calculated/planned. Good news shebi? ![]() Why didn't we buy 8pcs or did the Architect cut corners? ![]() I looked at the pictures and saw the front chilling spot is yet to be done; both the columns/pillars and beams/lintel. Running calculation estimates to see if all is well: Beam Dimensions are 3m +5m + 3m = 11m lintel length 4 qty x 11m rods will be needed for reinforcement Column Dimensions are 4.4m high min for each, we have 2 columns qty-2 11m rods cut in two (as explained above) will complete one columns. We repeat this for second column. qty 4 x11m rods will finish both columns. Grand Total = 8 rods no longer missing... QED No mind me, I too like book ![]() 1 Like |

The actual length of partitions dug for the foundation was 53p, this also translates to the length for a foundation beam or lintel full chaining. 1. For the Lintel. 1p = 12ft, 53p = 194m The kitchen store has been eliminated, this gives us 3m less length New total = 191m as chaining distance/length of beam 1 Qty 12mm thickness rod was measured as 11m length 191m / 11m = 17.4 pieces 12mm rod will run the full length of the lintel 4 qty rods needed for a full reinforcement; 17.0 x 4 = 68 pcs in total needed for entire beam 2. For the Columns. Height from current DPC state to 3 courses above lintel = 4.4m approx Rod length = 11m, when split into two this gives 5.5m each A column will now need 4 sides with rods, height 5.5m each = 2 qty 11m length 12mm-rods to complete our reinforced columns 23 total columns as designed = 23 x 2 qty 12mm-rod = 46 pcs in total needed for the entire columns Grand Total 12mm rods = 68 + 46 = 114 pieces total |

1.6 Lintel and Columns costing - Closed Lengths of about 190m of lintel chain and 115m columns. Maths incoming... Bought 12mm x106 pcs = N530k 8mm x43 pcs = N129k These iron rods don kill me! ![]()

Olumighty123:I even hate thinking about it. I have been looking at the design from day1 we started building and thinking of where a battery pack will be kept, never planned to do solar but it's wiring is very likely so as to make the build 'future-proof'. greenermodels:This will definitely be done during wiring as you stated but actual solar hardware will be in the distant future. Never knew of 3-way changeovers, thanks for the heads-up. 1 Like |

Soakaway construction is Ongoing by the side. I'll try to separate it's materials from every other thing but that might be hard. Labour cost only for all the block and column works will be N100k, casting the top slab NOT included in this price. Previous threads have said a Soakaway usually costs around N400k for everything (all labour and materials starting from digging to final top slab). Still depends on size, mine is larger than I thought it will be. I no deh price labour too much or not at all, they work hard so their pricing is fair. 1 Like

Olumighty123:The problem is what it will be powered with. Electricity is one of the greatest headaches I have going into this. The matter tire me. That's why I am doing many windows of larger sizes to make use of daylight. |

Borehole planned as one of the next steps. Quote is N2m ![]() Cost looked like a joke at the beginning but that's what it costs here. Available borehole drilling rig company has a reputation of not wanting to dig further after hitting first spout of water; people complain the water is unclean and can barely be used after spending so much. Intend to find a different company hours away from the building site. |

MackyNaija:I had mentioned 1bag of cement can stack 70 to 90 blocks. Just read another thread that says it can be 65 to 75 blocks. This is very likely as this stage hovered around 70 blocks per bag. Lintel construction ongoing, I have officially stopped checking the days... Labor and weather delays have crippled us. Workers show up whenever they feel like it so I have adapted to work with them that way. ![]() I also started giving monthly bonus pay to the most frequent worker - a mason won for April. ![]() 2 Likes

Lintel and Columns casting in progress, the rains have slowed us to only 2 or 3 working days weekly. |

kaze4blues:I just saw you asked about the estimate; estimate was 5,600 including the foundation blocks but we built a higher foundation than planned so we used more blocks there. The actual quantity stacked from oversite to lintel was 3,674 (10 blocks to lintel, my windows are a little larger than normal also). I earlier gave foundation qty stacked as about 2,300. We'll still use some more for 3 courses after lintel. Will mold more if it's needed. See costing for 1.5 Oversite to Lintel 2 Likes

kaze4blues:I'll share the block figures by tomorrow. What did the Architect say the correlation is between 9 inches and keeping your house dry? My understanding is that all blocks (sandcrete) will soak up water if exposed to water. - high foundation so your house is not soaking in a flood will prevent this - Isolation of ground water from the superstructure will prevent this (use of damp proof material) - Sloping the floors away from the sides of the building will also prevent this. |

Rany4all:You get mind o ![]() Doing 10 to lintel and I am feeling it will come falling down. What did you do post lintel? Is it possible to use lintel as roof beam? Just thinking... ![]() |
![]() |
greenermodels:Rany has explained some of this. 1. I need a high ceiling but want the lintel beam to carry less courses. 10 before and 3 after instead of 9 before and 4 after. 2. I am planning on using tall windows of 7 courses for the living room (see the attached picture). If I do 9 to lintel, window will start at level 2 which might be too low. So 10 to lintel allows us start the window at Level 3.

1.5 DPC to lintel - Still Ongoing Any estimated duration will be multiplied by 2 or 2.5, the speed slow die ![]() Regular threads I have been following show neck breaking speed, if you are supervising this yourself... na snail speed o ![]() Pictures showing: Back side at 10 courses awaiting lintel beam (all round chaining) Front side gradually getting there. 1 Like

Olumighty123:Chairmo, I full ground o. Doing fine too. Learned a lot from this section so it's my turn to give back, there's plenty info for building on NL but it's in a million different threads. |

eziokwunwoko: At the beginning I said the floor area was 13m x 18m = 234 m2 89 + 6 = 94 total bags (6 bags remained from the earlier stage). Months earlier I had used 233 m2 for a calculation I did (check abdul's links I posted at the beginning) See a summary: - Floor area is 233 m2 x 0.1m = 23.3 m3 (assuming 4inch oversite thickness which is 100mm or 0.1m) - Divide the concrete volume needed by 7 to get the resulting number of cement required for the project. 23.30 m3 / 7 = 3.3 m3 - 1 bag of Cement = 0.035m3 (a 50kg bag of cement is equal to 0.034472m3) - Total cement qty needed = Floorplan vol / one bag portland cement = 3.33 m3 / 0.035 m3 = 95 bags So actual and calculated are almost the same. I care less about sand and gravel because it's either a full truck is bought or it's not, no jipiti for those. This is how I verify quantities and payments for almost everything as I am absent. I trust my site Architect also so his reporting are accurate. |

Racing to lintel. Burial this weekend will stop work, next week has a better weather though so we should be good.

Clarification: Soakaway digging done, casting undone. Will dig a little more on all sides to get fresh soil before casting. Major interest now is to get to the roofing beam. Rain wan finish the workers for site and it's slowing down work. Yet to see the report but I am guessing they'll still be paid day rate as long as they show up. ******************** The journey continues: 1.1 Block molding - Done 1.2 Foundation to DPC - Done 1.3 Soakaway and Filling - Done 1.4 Oversite concrete - Done 1.5 DPC to lintel - Ongoing 1.6 Lintel to roof 1.7 Roofing |

The journey continues: 1.1 Block molding - Done 1.2 Foundation to DPC - Done 1.3 Soakaway and Filling - Done 1.4 Oversite concrete - Done Oversite is now officially done for Nairaland purposes. I add cost and close the phase. "Missing" about N150k as it is not on the Architect's report and we don't know what it was spent on i.e. money sent but never shown on the report. If you wanna save cost, NEVER skip damp-proof nylon as capillary action go make water finish upto 1meter from foundation towards lintel. About N4.6m spent so far (Block moulding cost NOT part of this). 1 Like

The journey so far: 1.1 Block molding - Done 1.2 Foundation to DPC - Done 1.3 Soakaway and Filling - Done The costing for stage 3 is attached. I wish I didn't do these breakdowns as it breaks my heart seeing how much this things I thought were simple cost. Laterite trip here rolls over/continues from the previous cost posted. Your site size and especially the foundation depth heavily affect this cost. Note: For sub or superstructure, 1 cement bag binds 70 to 90 blocks. 2 Likes

Currently finalizing plans for window sizes throughout the house. They'll all be larger than normal. When this is complete, we kick off forming and raise the blocks to lintel. 1 Like |

greenermodels:Thanks but no be say money long o, me na office man but earning in usd is the major differentiator; some money deh remain when month end. Labour cost is also not expensive in Nigeria so building can be achieved as a bulk of the money goes to materials. |

The most difficult part of the entire project has been completed successfully. Cost breakdown incoming (losing track of this, only thing I am sure of is how much I have sent ![]() To keep track of costs hard like to physically build the house; supervising Architect deh try. Superstructure and parapet should not take more than 1 week. 1 Like |
