mavverick: Sorry I do not know my clients by their nairaland names. However I usually collect site visitation TP before I visit any site. Because if I a giving free consultancy/professional advice on projects for co-NLders at least they foot my TP. And ever week I visit minimum of 3 of such sites. And as you can attest I give expert advise to ALL my clients. |

Hello Engineers/Builders in the House I hope you can help me with some advice regarding the construction of a long fence o my site. The fence in question (one side) is the long side of a 1.5 plot which needs to be constructed. Due to the cost implications of doing a raft foundation for this fence I have been advised to do the following to save some costs. 1. Do the blinding for the whole length of the fence 2. Instead of doing a raft foundation I use 3 coaches of 9 inch blocks 3. Pour cement/sand/granite into the 9 inch blocks 4. Use 6 inch blocks for the remaining coaches till we reach the desired height 5. Do the couping once desired height is reach Please note we will be casting the pillars as normal. Please advice. Will this work? Are there any other options that |

Fyguy, I have questions for you. 1. Tell us what soil formation we are talking about. 2. Have you done the soil test? 3. What type of blinding do you want to do? Ordinary blinding or improved type? |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by fyguy: 5:04pm On Feb 09, 2016 |
Thank you Mr Opalu, I always follow your work here. As matter of fact all building work has been done. It's just the fence that remains on one side. You have been to my site before if you remember. As for Blinding, its the ordinary one I want to do. The building has already been completed. opalu: |

House, Please I need to get some 35mm Coleman Reclen Cables. Does anyone know the current cost per meter? Also places where I can get them. Abeg I want original oo. No Fakes please I have been offered a few fakes (I can't imagine how we will even allow fake cables in this country) This is one of the many fire hazzards that we face everday. |

opalu: Uniform settlement is not also called monolithic. Monolithic is used for structural members that are cast at the same time. Cracks in plastering may be due to ultimate limit state failure or serviceability limit state. It may also be due to temperature changes (like plastering during hammertern season). Temperature cracks as to do with plastering drying too quickly. Plastering cracking may also be due to the use of very thick plaster. |

Adek15: 1: 2: 4 mix ratio can either be by weight or by mass. For a mix design it is by weight. For a critical job where the strength of the concrete is specify, either to be M20, or M25. The constituents aggregates is measured by weight but for normal work where the concrete is not specified it can measured by volume. By volume 1:2:4 means 1bag of cement to four head pan of sharp sand ( since one bag of cement is equal to two head pan of sand) to four eight head pan of gravel. 1 Like 1 Share |

abdulwastecx: What I mean is that when a building settles monolithically it is a uniform settlement. The main aim is to pass across a message. Using all these limit states terminologies will only confuse the readers most of whom are not structural engineers like you or me. |

Greetings, Apologies for derailing. Since I am so far away from my project site, I would really use some expert opinion on my case. Please I would like to seek expert opinion on the bill that I just received from my builder this morning with respect to the Completion of Roofing for a building containing 3units of 3Bed room (standard) flat in PHC. The details are shown below; Scaffolding Job: 1. Hard Wood a. 2x3x12 (200x300) = 60,000 b. 2x4x18 (200x900) =180,000 c. 2x4x12 (50x400) = 20,000 2. Nails =20,000 3.Labour =80000 Sub-Total = 360,000 Concrete Parapet = 500,000 Roof Frames & Noggins = 600,000 Labour (Parapet/Roof Frames) = 250,000 Construction of Tank Stand Deck =200,000 Stone Coated Roofing Sheet/Labour (Metrotile) = 1,000,000 Sub-Total = 2,550,000 Grand Total = 2,910,000 Grateful, for your contribution in advance. divaD. |

divad9two5:what is the length and breadth of the building? what kind of parapet does he intend to use? i think the quote is fair... but why is he using hardwood for scaffold, what abt bamboo? |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by divad9two5(m): 2:00pm On Feb 20, 2016 |
johnson232: Thanks for your response. Its length is about 19800mm and a 11700mm wide (hope I got the unit right). He wants to do an insitu concrete parapet instead of premould because he feels it is more durable. Since, I am going to stagger the finishing work by several months, he is proposing the use of hard wood due to its salvage value and ability to keep workers safe even after been beaten by heavy rain. Do you still think his bill is fair? |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by johnson232: 2:34pm On Feb 20, 2016 |
divad9two5:both parapet are good, it just depend on how it is done. if it is a bungalow, with this your dimension, i think the woods for scaffold are too much. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by Ballotelle(m): 5:32am On Feb 21, 2016 |
for a two storey building with average soil CBR I checked d column was to be given nominal reinforcement of 4 12mm bars. but suprisingly even some engineers are saying its inadequate .. what's ur view |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by johnson232: 6:03am On Feb 21, 2016 |
Ballotelle:12mm bars is inadequate for a two storey building. it has nothing to do with soil. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by obynocute(m): 7:45am On Feb 21, 2016 |
pls my ogas in the rum, wot is the cause of settlement and void on a floor slab, nd how can it be corrected. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by Ballotelle(m): 11:49am On Feb 21, 2016 |
johnson232:... pls inadequate based on a design u av ever done or based on assumption .. cause using oyenuga,, it was nominal reinforcements that is required |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by johnson232: 8:19pm On Feb 21, 2016 |
Ballotelle:Are u talking about the slab or column? If it is the column don't use less than 16mm. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by johnson232: 8:21pm On Feb 21, 2016 |
obynocute:Poor compaction. U need to break the void part and refill 1 Like 1 Share |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by opalu: 10:27am On Feb 22, 2016 |
johnson232: Thanks for the direct answer. There are other reasons like the nature of underlying soil. There are certain types that even compaction won't stop them from settlement. Another reason is inadequate foundation depth or width. Another reason is use of wrong type of foundation. Etc 1 Like |
