I will start with the setting out. These are the simple step we follow to achieve out design profile board We located the building line: this was made difficult because of the poor site plan that doesn't reflect the through nature of the site We have the proposed site And actual site (pencil sketch by abdulwastecx)

my boys need to clear the proposed building area so that setting can be done

day one setting out: in a simple man language, setting out is just the transfer of what we have in our drawing to the ground. for a frame building of one floor and above, we normally use the structural drawing (foundation layout of column bases, strip footings and foundation column point). these are the step taking 1. we set out the building line: the building line is the front face of the building in this case. this line is gotten by offsetting from the fence as prescribed by the architectural site plan but because the site plan was not detail, we have to use our site experience to get this line 1 Like 1 Share

from this building line the other two corners of the building are set out using " 3 4 5 " right angle triangle method . in this case, we use multiple of this triangle (12, 16, 25). these two other points were located and the profile was nailed after offset from these original four points 1 Like 1 Share

Re: Construction Of Six Bedroom Duplex At Enugu by abdulwastecx(m): 11:29am On Apr 12, 2016 |
excavation of the column base: before we can do this we need to make provision for the column base size. my carpenter will be called to action soon to construct a simple isolated footings form. we have about 40 columns and 38 column bases with two of these bases combine footing (a single footing carrying two columns )

Re: Construction Of Six Bedroom Duplex At Enugu by abdulwastecx(m): 11:37am On Apr 12, 2016 |
more information about the isolated pad footing also non as column base. we have two type of these footings as specified by the design enginner. pad type one with plan dimension of 1100mm x 1100mm and depth of 450mm (18" pad type two of two number with plan dimension of 1800mm x 1100mm and depth of 45mm (18" How do we achieve this on site? we get the job done by first digging the strip footings up to the required depth of 900mm and after that the space for the pad is dug down byand additional 250mm |
Re: Construction Of Six Bedroom Duplex At Enugu by abdulwastecx(m): 3:47pm On Apr 12, 2016 |
let me introduce all the reinforcement of the foundation. according to the structural design we have 40 columns , with links spaced at 200mm c/c (8") and we have 38column bases or pad footing with 36 isolated and 2 combined footings

Re: Construction Of Six Bedroom Duplex At Enugu by abdulwastecx(m): 3:55pm On Apr 12, 2016 |
we have to be very careful while making reinforcement and try my best to follow BS codes for bending and scheduling. according to the codes, all vertical member links must have anchorage of greater than 90 degree, it must be between 135 degree to 180 degree and that is why we bend our links in this fashion. our starter bar or foundation column 2.4m in other to have an anchorage of 300mm at the base and have a lapping of >600mm into the next column going up. these are very simple but vital information that most builder neglect but having a good knowledge of reinforced concrete design help us to allways follow standard no matter how hard it is 2 Likes 1 Share |

the column base were specify to be 1100mm x 1100mm and 450mm thick the reinforcement for the pad footing is 1100-50 = 1050mm, allowing a cover of 25mm both side. the spacing of the reinforcement is 150mm center to center , 1050/150 = 7 bars both ways making a total of 14 bar anchorage length of 150mm both side making a total of 1050 + 300mm = 1500mm total number of bar for the 36 pad footings = 12/1.5 = 8bars per each length of iron since i need 36 x 14 = 504nr of bars /8 we will be needing 63 length of Y12 for the 36 foundation footings for the remaining two combine footing of dimension 2100mm x 1100mm ( we realize that 1800mm x1100mm will be inadequate so we have to change the longer side to 2100mm) the pad is doubly reinforced because of the action or hogging moment

we need professional eye to get the job moving....day three on the job blinding of the column base, permit me to introduce my partner and a new father mr podosci.... we have 38 column bases and according the structural design we have the following information pad one 1100mm x 1100mm x 75mm (blinding for column base) pad type 2 : 2100 x 1100mm x 75mm (blinding for combine base) volume of concrete = 1.1 x 1.1 x 0.075 x 36(number of column base 1) = 3.267cubic meter volume of concrete for combine base = 2.1 x 1.1 x 0.075 x 2 (number of column base 2 ) = 0.035cubic meters total volume of concrete = 3.302cubic meters (increasing this value by 25% to cater for losses ) = 1.25 x 3.302 =4.13cubic meters for the blinding we are going to use 1:3:6 by weight (this translate to about 4.25bags per cubic meter) total bags of cement required = 4.25 x 4.125 = 18bags of cement since we are batching by weight, for sand we have 18 x 50 x 3/1000 = 2.7 tonnes of sand = 3tonnes of and for gravel = 3 x 2 = 6tonnes of gravel

day four setting of foundation column and ready to cast
|
Re: Construction Of Six Bedroom Duplex At Enugu by abdulwastecx(m): 5:29pm On Apr 12, 2016 |
for home builders things to note: the column must be centralized on the pad footing to have zero eccentricity because eccentricity create additional bending towards one of the axis or the two axis of the pad footing ( we have the y-axis and the x-axis) 2. the anchorage at the connection of the column and the pad footing must be big enough to allow adequate lapping in this case we have 300mm lapping 3. the footing must be blinded to protect the reinforcement from moisture from the soil below which may cost rusting of the reinforcement during the service life of the reinforcement. 4. combine footings must have both top and bottom reinforcement as shown bellow 1 Like 1 Share |
