 Good-Day, it's nice to be back and have you (still) around; I hope you find the information below useful (as you did the previous parts). To make things easy for everyone, I have modified the plan used in previous tutorials by adding a staircase and also showing proposed column points, (because we do not have a structural drawing, we would be working on a few assumptions to aid our calculation.) New plan attached below (we're not particular about functionality here; just estimation.) Note: Because it's the same design with Part 2, we would be making references to part 2 occasionally and using that to save us time and post length. LET'S GET TO WORK. *My post do not eliminate the need for an experienced supervisor/engineer on site - they are intended for education and negotiating purpose only. Thanks. If you're yet to read the previous parts, kindly do so here: Part 1:  https://www.nairaland.com/3502464/how-build-comfortable-house-earning   Part 2:  https://www.naira...

Good day all, So, I got a few 'likes' in the property sections to do this; designed for site supervisors, carpenters and welder/iron benders, contractors and DIY aspiring home owners. A lot of people have lost job opportunity because they 'over quoted' and others have fallen victim to under-quoting resulting in them running-away or abandoning the projects. We would practically calculate all the materials need for the below 3 bedroom apartment (plan attached) - at the end of this tutorial, I expect that your estimation of beams and slab (decking) should be better or closer to reality. Let's get to business - attached below is the slab (S1,S2,S3, etc) and beam (1,2,3, etc) design. Let’s get to business; below is a list of items we would be calculating. 1. Bamboo 2. 2by3 wood 3. 1x12 plank 4. 8/10mm rings in Beam 5. 16mm bars in Beam 6. 12mm bars in slab 7. Granite, Sand and Cement in beam & slab 8. Estimates for others (binding wires, nails etc) To get a more accu...

This is an amazing thread.... Please can anyone help with a rough estimate for fencing 6 plots of land close to Abeokuta, Ogun state.... I’m considering 10 coaches including foundation It's a flat and dry land. Estimation would include granite for any stone related job needed for the job if any. Also, which is advisable between single and double gated fencing, considering the size of the land. P.s I don’t have any major plan for the land at the moment. But I want the fencing done asap after lock-down. Thanks in advance SOLUTION The first thing is to ensure the arrangement of the plots are known as this affects how much material is used. (see pics 1 for different arraignment) The second note is the type of foundation needed, and in this case; its a strip foundation (Abeokuta is a rocky or 'Laterite' land) The 3rd important information is the SIZE of the plot, although it wasn't stated, he confirmed it is 18m by 36m a. Lets find the LINEAR METERS of the pro...

GoodDay and its good to be back. Let's go practical (as we always do) - calculating the quantity of tiles needed to tile various spaces within the building (floor and wall tiling). We would make reference to our 3 bedroom plan, designed specifically for this lectures and calculate the tiles needed in the Living Room, One of the Bedrooms and the Master's toilet's floor and wall tiles. SELECTING TILES 1. Tiles come in various sizes, the common ones being 150x150, 200x200, 300x300, 150x300, 200x400, 300x600, 400x400 and 600x600; the first thing to do is pick a tile (based on clients choice or use) for each floor and wall. There is no rule stopping you from using any particular tile size for floor or wall, as long as it has the perfect surface finish for that use. e.g, a glazed (slippery) tile is not appropriate in the bathroom, so if I find any non-slippery tile, irrespective of the size, I can use it for my wet floors. Wet floors includes Bathroom,...

I've been wanting to do this topic but couldn't come up with the easiest way to teach it; while it is possible to measure the quantities of roofing sheets needed for your project even before you set the first block using the Architectural drawings; it requires a lot of experience especially in trigonometry and site visualization. I have however found an easy way around it; as would be discussed below. I have carefully designed and attached a roof plan for this purpose, (feel free to use should it fit your building design... lol) Calculating the quantity of roofing sheet needed is done is meter square (m2), same parameters used for selling and purchasing roofing sheets hence we would expect to use the AREA FORMULAS (i.e Area formulas for Rectangle / Square, Triangle, Trapezium and Rhombus), sounds easy right? Yes it is!!! The most difficult aspect of calculating Area of Roofing is FINDING THE TRUE LENGTH (Technical Drawing students should understand this)...
