abdulwastecx:Sir can provide answers to the questions below respectively; Then why is pile foundation used for skyscrapers as against strip foundation with shallow depth? Why does a 3 storey building requires a deeper strip trench than a bungalow? Why is the base of a 3 storey building deeper than that of a bungalow? If u say width is necessary to spread load as height of building increases, i will understand. But saying height doesn't determine depth is what i will find hard to believe. Even for water tank stand, i believe a tank stand serving a 3 storey building will require a much more depth than that serving a bungalow. 1 Like |

(CNN) At least four people died Thursday when a pedestrian bridge collapsed near Florida International University, Miami-Dade County Fire Chief Dave Downey said. At least eight cars were crushed under the bridge and at least nine people were transported to hospitals for treatment, authorities said. The bridge's span was just installed Saturday, an effort to boost safety on a busy street where an FIU student was fatally struck by a vehicle last year. It is unclear why the bridge, which was still under construction, collapsed onto a busy state highway. A statement from the university said that Accelerated Bridge Construction (ABC) technology was used in the construction of the pedestrian bridge. ABC streamlines the building process so bridge construction projects can be completed quicker and be more cost-efficient. State Departments of Transportation use ABC technology to refurbish or construct bridges within 48 to 72 hours, according to the Federal Highway Administration (FHA).

Rubbiish: Okay, I will try to do justice to your question, sir. Then why is pile foundation used for skyscrapers as against strip foundation with shallow depth? Before I answer this question, I will like to explain that pile foundation is used for a skyscraper or high rise building because the load coming from the structure can't be safely carried using a shallow foundation like a raft. In cases where a raft can carry the supposed building, a shallow foundation is used. There are cases where the bedrock is very close to the ground, or very stiff clay or granular soil with the right property to carry a high rise building is very close to the ground, in such cases, you don't need a pile foundation or very deep pile to carry the building. In conclusion, The height of the building influence the loading intensity through both gravity and especially lateral (wind load) loading of the structure but is not the factor that determines the depth of the foundation. Why does a 3 storey building requires a deeper strip trench than a bungalow? It depends on what type of foundation and the nature of the building. If you are building a three storey building with load-bearing walls, where you will need to provide a strip footing for the walls, the strip only needs to get to the soil strata with adequate engineering properties to support the building. But, when you are building a frame structure ( the best type of structures for a three storey building) you only need your pad/isolated/combine footings to get the surface of the soil with adequate soil properties to carry the structure, while the strip footings for the partition walls will be of similar to that of a bungalow or can me omitted totally in favour of a grade beam/plinth beam. Why is the base of a 3 storey building deeper than that of a bungalow? This is not apple for apple comparison, It is deeper because it is heavier and most cases the type of foundation employed differs. A bungalow will most likely have a strip footing while a three storey building will most likely have a pad footing for good soil or raft foundation for poorer or expansive clay with large anticipated differential settlement (this foundation can be shallower than that of a bungalow) or in extreme cases a deep pile foundation 3 Likes 1 Share |

Hello everyone , this is a wonderful thread and kudos to all the contributors. Pls I need your help. A culvert is to be built on a property and the attached was quoted. Pls does this look okay. I already know the granite price is not okay and I will be challenging it. Thanks

abdulwastecx:This your first point further buttress my point. Why can't a shallow foundation carry the load? Is it not because of the height which will definitely increase the weight of the building? All these engineering calculation all stems from simple logic, u need to see the sizes of columns supporting bridges, they can never be same with those supporting a concrete parapet for bungalow. I will never accept same supporting column sizes for bridges & parapet because of calculation.... We use 12mm for bungalow reinforcement, but it is not recommended for duplex, i haven't use less than 16mm, because as height increases, load increases....Applying engineering principles doesn't stop logic.... 2 Likes |

Good day my people, and peace be unto you. I want to construct a water tank stand for a four 3 x bed flats one storey building (ground and first floor). Which is better (or cheaper), metal stand or brick/concrete stand, and roughly how much will either cost (materials and labour). The area is Ota in Ogun State. The stand is for 2 tanks (about 2000L each). Thank you |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by snakebeat: 12:54pm On Mar 16, 2018 |
Rubbiish:@emboldened true. U can't really seperate height from depth in construction, same principle apply to cantilever, the protrusion should also be maintained on the other side. It is simple equilibrum. Take ur NGL as centre point, but doesn't work 100% for foundation, but same principle & idea. |

Rubbiish:price for sharp sand was not included because we have that on ground. I have a problem with the cost of the granite though. Any idea how much a ton costs normally |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by snakebeat: 1:02pm On Mar 16, 2018 |
rabcnesbit:Better; go for H beams steel Cheaper go for 4" galvinized pipe or concrete. But i normally advise steel stand, because one may need to utilize space in the future, u can easily relocate steel stand, but concrete stand is not moveable. |
