mufutau55: This is 6cm thickness. N3,774 per sqm is way too much. You can put a call to any interlocking company. They can never charge that amount for casting and laying even if you’re giving them the whole contract. I recently completed almost 6,000sqm of 8cm thick interlock bricks of the same shape. It’s way cheaper than N3,000 per sqm. Most people don’t use 8cm thickness. I’ll share the breakdown of material requirement shortly. Edit: Now, I understand why your figure went up. The cost includes sandfilling of the compound. I stopped counting when we poured over 200 trips of filling sand into the compound. _______ I just got my ID back from Nairaland spambot. #brabusinterlockDIY 2 Likes |

QSFemi: Bros, I get where you are coming from and I get why you have arrived here. First of all, you seem to confuse Construction Estimator (US) and Cost Engineering. US uses Cost/Construction estimator while UK uses Quantity Surveyor which have the same job responsibilities. Why you didn't get to where I expected you to be is as simple as, you think Engineers look down on your profession. But for someone like me who has sat in same class, shared hostel accommodation and kept as best friends, not one but 2 QS guys, I know better than that to know that their profession is actually intricate and could bring such a challenge even bigger than the innovative design of the Burg el Arab. This challenge is the very thing that limits your profession leading to the creation of a more specialised and very narrow Engineering discipline that is birthed by yours. It is the unfortunate reality. Cost Engineering is not a Nigerian thing my brother, please read about it. Its not even common in Nigerian schools for one very obvious reason, it is specific to a discipline unlike QS that is broad. Costing a space ship requires indepth knowledge of the ship. A cost Engineering is a bridge between Engineering and QS having less of both professions. The limitations of your profession is that you provide an essential service to the entire Engineering discipline but cannot keep up with any. At a level, you need the Engineering training to do your job which becomes a challenge. For example, to build a power transmission line, an Electrical engr determines the current, voltage, resistance etc while he works with the material engineer who gives him the type, structure and size of material to use, together they develop the heat limits and behaviour of the material. The civil engr joins them to determine the tensile properties of the material and sagging behaviour under different temperature/wind conditions while determining the reactive forces on the tower and its foundation, tower spacing and height etc, while maintaining required levels of safe electrical ground clearance given by the Electrical Engr. All Engrs work to get a design that fits the electrical engrs vision. At the end, a QS is called to provide a cost estimate but has to do sagging calculations just to get the total length of the cable. These sagging calculations are affected by thermodynamic and others. The QS isn't trained to do sagging templates nor the thermodynamic effects and cannot calculate the length of cable. 2 disciplines can, a Civil or mechanical engineer but not a QS. This gives rise to a new professional who has the sagging calculations abilities and has the QS training. I don't want this to be an argument but I implore you to research the subject, (difference of QS vs Cost Engineering). 5 Likes

On interlock, here are important things to note: For 6cm thick mold only 36 pcs of stones make 1 sqm using Double T 36 pcs of stones make 1 sqm using Zenith shape 50 pcs of stones make 1 sqm using “I” 30 tons of Stone Dust will produce 280 sqm of 6cm thick stone 1 bag of cement will produce 3.5sqm of stone. Good pigment to add colour is sold +/- N50,000 per bag. Labour charges varies from 500 - 700 per sqm for casting and laying. This depends on your bargaining power. Some people will even charge you more if they notice you have no idea. Compactor rentage is between 10,000 - 15,000 per day. I have my compactor tho used for the project. https://www.facebook.com/199049746782483/posts/3778095355544553/?vh=e Don’t mind the heavy guy posing on the job ![]() ![]() #brabusinterlockDIY #compactor 6 Likes 3 Shares

Crunching the Numbers Here are few things I paid attention to while executing the project. _____ I bought full 30 tons of stone dust N75k. I know most people will buy a lot more expensive in some areas in Lagos. I later got to know I was cheated at the end of the project. I got 70k per 30 tons truck. In Ikorodu, I got the same quantity for N105k and even more expensive in Ajah. More reason, I want to buy another dump truck now. _____ Mould rental per day is around N3 per mould. In 30 days, I would have paid over N90 per mould. N90 x 3000 moulds = N270,000 New mould is sold N90 - N120 (6cm), N120 - N150 (8cm) So I decided to buy 3000 moulds instead of renting. Just imagine the huge savings. _____ Plate compactor is sold N180k and the cost of hiring is 15k per day. I need it for about 20 days. That means I’d have paid 300k renting a 180k machine. So I decided to buy one. Throughout the project, we were never in a rush to use the compactor. brb. #brabusinterlockDIY #compactor 6 Likes |

n3xt: Yes Sir. The cost includes sand filling, materials, bricklayers, levellings, kerbs, bricks, contractor supervision fees etc. Everything that completes the job. I had some granites and bricks left. Oga Aventures was my Contractor. Like I said, if I was on ground I would have saved some cost. Before I forgot, it includes 50k to repair my gate that the drunken Chekitaut driver broke when delivering stonedust, and I never recover the cost for the damages. ![]() Hajji M. 5 Likes |

mufutau55: Direct costs are usually the largest slice of the cost-component pie eating deep into most homeowners’ pocket. Cutting them goes a long way toward getting more projects completed. I think the aim of this platform abi thread should be (moving forward) to explore ways to help homeowners reduce direct costs. The one that quickly come to mind is “bulk buying” abi na cooperative buying ![]() I paid very small amount of money for casting and laying of the interlocks because of the volume involved. I told the subcontractor “I can keep you busy for the next 2 months if you’re willing to accept XYZ amount.” Allowing subcontractors to use pricing methodologies that don’t accurately reflect reality is a sure way to overpay. How can I pay N4,000 per sqm and still pay same for 1,000sqm? Costs aren’t linear na. ![]() Using simplistic mathematical pricing models benefits the contractors rather than lowering costs for the homeowners. I once sold sandcrete block N120 per block when everyone is selling N180. In my ongoing project, I sold N150 and they were 100% better what we bought N220 How? The first client have a dredging site. I have a dump truck and electric block moulder. So I decided to produce the blocks at a cheaper rate as a complimentary service. I’m the builder and I’m not buying sand the same rate as everyone else. Why should I kill the project in order to satisfy my craving? The second client needed about 17,000 blocks for his project and I know we can save up to 500k if I use my machine. The same thing applies to formwork. If there’s one thing I hate most on project, it’s the amount spent on formwork purchase on individual projects. That’s why I’ve invested heavily on formwork. If homeowners/owner-builders find away to cut some of these direct costs, we might actually have find a way to build affordable houses in Nigeria. I’m never bothered about rising cost of cement and steel, I’m bothered about paying more for lack of creative/innovative solutions. 5 Likes |

Mjolnir: If you think the cost of wood is too much, discuss with him about buying the materials yourself at your own preferred sawmill. If he will climb up and come down, I think 80k is not too bad for a renovation job. Here’s my piece of advice: 1. Negotiate with him and be upfront with him about your budget and projections. 2. Don’t assume it’ll be cheaper. Renovation is never cheap. 3. No builder has X-Ray vision when it comes to renovations. Brace up to spend more. 3 Likes |

flekky07: May I ask which part is unrealistic. The labour rate? The price of cement? The unquoted price of stone dust? The price of diesel? The cost of renting compactor? Or the quantities? Or the number of stones that makes a square metre? Or the uniqueness and peculiarity of each site? Some site will require just 5 loads of sandfill while some will require 50 loads. Or the site challenges? edit: While you require just 30k to transport stone dust to some site, you may end up paying up to 80k to move same quantity of material to some other site. If you don’t get right quantity of materials (stone dust), it’s not the fault of the estimate. It’s because you’re ripped of. #brabusinterlockDIY 2 Likes 1 Share |
