Rexceedo: If you pay for labour who will supervise the building and read out all drawing in relations to another and also look out for conflict. If you have the fund gve it out to an engineer Or contact a Quantity surveyor get all materials on site and pay for the supervisor service fee and negotiate labour |

abcivilengr: 1.85m or so SAFETY CONSIGN Take note of all loads acting on it and if there's any partition on such slab it must be account for .. if a partition is not on the architectural drawing pls assume there's and load the edge of the cantilever because the design maybe review during construction The detailing aspect is crucial the tension bar should be return by 1.5L of the cantilever span.. Its safe and possible when design properly.. cost wise If you not really comfortable with it and wall load will be aligned to the edge use upstand beam this will reduce the depth of the slab and other sections because initially u will have a dipper beam section to counter the effect of the cantilever. 1 Like |

segzyfunmi: No one will do over site conc. at that rate some practical reason . Cost of boarding the edge (carpenter will charge you) The carpenter still needs to be there should in case of unforseen event Cost of machine and operator If you settled for hand mix Manson will charge more to mix. Over site conc. Mix becomes harder heavier than just blinding When labor hear concrete forget it they will likely not take 1500 except all stages of work is guarantee for that gang.

megacontrol: Ok i will explain the 20mm for maximum aggregate size is no 6 in the general note you uploaded ..I did not use cover to determine this .you will notice the cover for your foundation , beam, column , are all different because this are major element as an example the reaction of the soil can have some great impacts on the concrete which may attack your rebar and this will lead to loss of strength, this cover is determine by ground conditions for column/beam etc weather condition and fire rating to protect the reinforcement one of the advantages of concrete building though.. i think 3/4'" down should be in the range of 3/4"' to 1/2" sieve varying . I stand to be corrected though 1 Like |

megacontrol: size of aggregate use is always determine by the clear cover of your structural member , check your general note you will notice the size of aggregate for each structural member.. in most cases we use 20mm coarse aggregate after factoring the cover after placing your rebar(iron) for you not to high have pores which leads to weaker members at times... contractor then prefer to go for lesser size for some reason clean job because of workability problem with higher size of granite, when they use this granite size it makes them save in labor cost due to time and more job recommendation because you see everything when the formwork is removed comes clean .. in your own case for now any structural discussion one have to have a clear scope of work before giving advise do you have beams you want to cast together with this slab and what size is the width and how many number of reinforcement do u have at top and btm . how close are you to a fire station ? purpose of structure? for you to have a 175mm slab we may likely say deflection plays a major role in your build also .. in any ways pay attention to workability and don't go and cast grade 15 in the name of making concrete workable. 1 Like |

Good morning all, On the issue of reinforcements using local bar , TMT et all., and the cost implications ,strength.. The designer of any structures choose the grade of steel he/she intends to design with, this grade will be clearly written at the 2nd page (general notes) or on each page footer of the S.Drawing, the implications of this grade choose for your project will determine robustness , number of required required reinforcements in each structural member Lay example below. If I use 410n/mm2 say column of (230x230mm) for a duplex it may requires 6 nos of T16mm and use grade 460 for same column it will require 4 no of T16mm (assumption), the implications of this is that if baba lati supervise for u he will do the following 1)Tell you he built same thing at honourable place @ lekki they use 4 No's of 16mm and the structure is still standing till today. 2)This Engr is not considerate 3) charge you for same 6nos and put 4 No's inside, And cast forgetting or lack d knowledge of variables and notes in the Drawing. To the main discussion we have various kind of steel in the market , which most are very bad and good only known brand can easily be passed , most of all this local steel of unknown origin are having same properties as plain bar(unthreaded bar (that iron we use for burglary then)) .. How do you recognise all this in d open market? Its difficult for small project since u will b procuring ur steel in batches and from cheapest source available ,u will likely not run a tensile strength. Large projects and mindful owner (contractor) make use of standard and mostly consultant is always on site contractor will b mindful else he will waste money when ask to break concrete and re do and he looses credibility gradually because during next meeting on a job and such contractor name is mention we strike such out without d company knowing self. Summary Buy iron brand that's traceable with clear identification on it Never reduce or propose what's not in ur drawing without ur designer consent Quantity surveyor should always quote reinforcements using quality brands price because contractor will not buy TMT when u quote local to make thing's cheaper TMT is good , local is likewise good if you are running a test or buying good one 8 Likes 2 Shares |

michlins: You made mention of the foundation, how do you calculate this load and transfer to the said foundation ? Wind is a major factor too. Reason same materials may not work is because of wind I will gve a brief lay example below.. If you build close to sea or open up area or hill where no winding breaking occurs at much such section may likely not work except for proper bracing compared to building such stand at Ikeja where its relatively developed or behind ur building.. The base plate, stiffeners, bolt ,welding even painting are all recommended. The reinforcements in the foundation how do you go about it? Do u know which is the main direction, do you know where to splice your section or how to connect back such. From your believe what engineer does is use same section change the wind pressure to see if it works and check the load against the Soil bearing capacity of same area Sir it work's u r good to go if it doesn't adjustment comes in and modification Sir. I will provide you with your next 3 project on this tank stand drawing free since I notice this is what most people want to contract your service for here.. You will make a good fabricator since you are technological inclined , https://www.nairaland.com/3522155/iron-tank-collapses-secondary-school 2 Likes

Good morning All, I need to give some observation, read carefully. As a silent reader I notice the trend of everyone wanting a steel tank stand, and materials suggestion keeps going on kindly notice the following. Steel section are choose from expected load (tank size) ..but the bracing are always strategically place to reduce section at times or for stiffness purpose If a steel section works in Lagos for example doesn't mean same will work in Abuja the wind pressure in each state in Nigeria is significantly different according to the wind isopleth data, so when assume this is always dangerous.. Section like UC, UB Angle iron etc all have minor axis and major axis meaning the direction of face are of important, reason you see people using CHS (recommended sizes) u don't have to worry about any local bending its strong all through . The base plate need to be check like wise the HDB(hold down bolt) The foundation this is important and done with three things put into consideration (weight of the steel ,wght of water , wind reactions on the structure ,live load of access also) Not to bore you much your tank may be over designed (waste of money at least safe sha) or under designed (total waste of money and intending disaster waiting to happen) A tank stand is a structural elements you should never toy with it because its failure is always a serious issues. 17 Likes 1 Share |

Rexology: The wall section is not sufficient to take the self weight of the beam itself now u have ur roof load wall load and self weight of ur beam on the angle not more than 225mm max.. if the lintel had come out a little beam u could have lap it well there's always a satisfactory lap for this kind of thing it can kills when there's an uplift action from wind and u tie ur roof to this particular member at the terrace solution from my own view since the load is small u can introduce a dummy column to receive the stress ..safer this way since we can't estimate how solid ur strip is or block.. 3 Likes

jajeri3216: I don't know if other members already suggested a solution .let me add one or two things, How many floors is the said structure ? Is the crack progressive? Years of Usage? Residential or any other usage? Is there a column at that particular edge and can u make a video.. If its your column there's an issue and not something you should listen to the comment of a get a PhD bricklayer, who don't understand load analysis and distribution of a structural system.. Standard Solution Share your structural drawing The building will be re analyze to see where the problem is coming from Structural assessment and integrity test On all or selected members Etc.. Kobo kobo solution( Assumed solution) A UC or UB will be use to support the column and the previous one will be repaired. Assumed selected section.. Note all this if its ur structural element that's is mis behaving All said above are based on the picture I see solution may changes .. Be guided professional builder's dear not alter a structural element without approval from the designer not to talk of expert mason 1 Like |
