Build Perfect

 

  This is a general question and the answer is subject to many factors as such. The answer is tentatively 2.0 metres x 2.0 metres isolated footing. The foremost criterion is the Safe Bearing Capacity(SBC) of soil(bearing stratum). Secondly the Final reaction coming to the column. That depends on factors like type of construction like walls, type of occupancy for live loads, dead load intensity and most important the span of beams(spacing of columns). Assuming a load of 300KN/floor and SBC of 250KN/SqM , 2 metrex 2 metre footing is satisfactory. Generally 1.5m x1.5 m to 2.0mx2.0m is applicable. area of footing = Load on footing/Safe Bearing Capacity of soil. it gives the area. You can choose the geometry according to you. It's based on some failure criterion. Most important of them are: Shear failure- one way & punching failure Flexure failure Bearing failure Failure due to excessive bond stress.

  The foundations of the building transfer the weight of the building to the ground. While 'foundation' is a general word, normally, every building has a number of individual foundations, commonly called footings. Usually each column of the building will have its own footing. Since the weight of the building rests on the soil (or rock), engineers have to study the properties of the soil very carefully to ensure that it can carry the loads imposed by the building. It is common for engineers to determine the safe bearing capacity of the soil after such study. As the name suggests, this is the amount of weight per unit area the soil can bear. For example, the safe bearing capacity(SBC) at a location could be 20 T/m2, or tones per square metre. This capacity also changes at different depths of soil. In general, the deeper one digs, the greater the SBC, unless there are pockets of weak soil in the earth. To properly support a building, the soil must be very firm and strong. It is co...

  I am a civil engineer by profession and had been a part of several small and large house construction projects in my locality.  purchase your own building materials, but don't stock it, keep regular supply as and when required. Material wastage is a big loss especially when cost are running high. Appoint a labourer contractor for construction. Never pay them on daily basis. Fix the total cost of construction in advance based on sq. Ft basis. Never pay to anyone in advance, always pay after material delivery and after work is completed. Visit your construction site everyday, spend time with workers and understand the work so that they don't take you for a ride. 5 . Visit nearby construction sites to see there working and also have a survey of material shops to evaluate who is selling better material at reasonable price. 6. Get the plan of your house and cost finalised beforehand to ascertain everything is within budget.

  The ultimate purpose of borewell is to  “get good water yield ”  for domestic usage, so let’s discuss it from that point onwards. Take a pen and paper and write down few points before digging the 2nd one. Is yr individual house already constructed or is it yet to be constructed (provided yr land is a vacant site now) At what depth did you get yield on your 1st bore well How many years before did you dig your 1st bore well How much available space do you have to dig a 2nd borewell (you need to check columns and beams, tie beams of foundation) How many 3 plus floors of apartments do you have in your neighborhood Is it really worth the expense Do you experience water shortage only during summer or round the year Do your neighbors have the same issue Once you note down these answers, you will get a rough idea about the “ available distance” between two borewells or bluntly, is the 2nd borewell worth it. Now you need to consult with a  “ licensed water surveyor”  w...

 Type of Boring 1. Machine percussion drilling   2. Manual percussion drilling   1. Machine percussion Boring: In machine percussion drilling there is no limitation of depth.  If the boundary has been done before boring we need space to fit machines approx 0.7m to 1m. Avoid building boundaries before to save space. 2. Manual percussion Boring: In manual percussion boring there is limitation of depth. North East Corner is auspicious for Boring.
