    Built-up area and super built-up area is generally used in real-estate. It is used to calculate the cost of property per square feet or square meter.

    The built-up area is the carpet area plus the thickness of the outer walls and the balcony. The Super built-up area is the built-up area plus a proportionate area of common areas such as the lobby, lifts shaft, stairs, etc. Sometimes it may also include the common areas such, swimming pool, garden, clubhouse, etc.

    The carpet area is the covered area of the usable spaces of rooms in the building. It is measured between walls to walls within the building and is the sum of the actual areas of the rooms where you can carpet.

    Now, when the total cost of construction of a building including the cost of land or plot, is lets say, USD 10,000 and its carpet area is 1000 sqft, built-up area is 1250 sqft and super built-up area is 1500 sqft, then the cost of the building per square feet can be calculated as:

    Cost per sqft of carpet area = USD 100,000/1000 = USD 100

    Cost per sqft of built-up area = USD 100,000/1250 = USD 80

    Cost per sqft of super built-up area = USD 100,000/1250 = USD 66.67

    In this way, you can arrive at the actual cost of construction per square feet including the cost of land or plot. This can also be used to calculate the selling cost of the property.

    T-beam is simply rectangular beam cast monolithically with the slab.

    Advantage os T-beam over ordinary beam:-

    1. T-beam casting with slab as we know so Its flange takes compressive stress and that mean It will resist more sagging moment of beam.
    2. Depth of beam is reduced as compare to ordinary beam so better headroom advantage.
    3. Over longer span T-beam is used rather than ordinary beam for reducing the deflection of beam.

    Here if the matter comes about higher modulus of elasticity between rubber or steel then we can say steel is more elastic than rubber. We know that young’s modulus is the ratio of stress to the strain. Therefore, for a given stress, the strain produced in steel is much smaller than that produced in rubber. This implies that Young’s modulus for steel is greater than that for rubber.

    You know what that the on-site evaluation of concrete strength is the biggest challenge in the condition assessment of existing infrastructure for the quality control of new construction.

    All parties agree that the strength of concrete is a critical parameter

    1. Compression test on concrete Core

    2. The pull-out test

    3. Rebound hammer for concrete strength

    4. Ultrasonic pulse velocity

    5. Combined non-destructive testing methods

    shrinkage limit is the maximum water content at which if we reduce water content further than soil volume doesn’t change,

    we can also say that at shrinkage limit, water is in just saturated stage.

    let’s see the graph of water content and volume change with shrinkage limit

    ws= shrinkage limit

    wp= plastic limit

    wl=liquid limit

    at below shrinkage water content water is spill out/remove from voids of soil and that voids fill with the air. Hence voids doesn’t change, so volume doesn’t change. and soil become 3 phase structure air, water and solid particles.

    Meridian lines, in addition to marking lanes, provide necessary guidelines, instructions, and restrictions on roads. Yellow and white are the most common ones. There is no difference in the roads marked by yellow or white lines as such, but only the instructions given by them are different. Their relative occurrence varies from country to country.

    Soild white line: a solid white line along the curb or between two lanes means that switching lanes and overtaking is disallowed until the line changes.

    Broken white line: a broken white line is found between two lanes or in the middle of the road. It means that switching lanes or overtaking is allowed and safe.

    Solid yellow line: a solid yellow line between two lanes means essentially the same thing as a solid white line. A solid yellow line along the curb means that parking at the side of the road is disallowed.

    Double solid yellow line: a double solid yellow line down the middle or between two lanes means that overtaking or switching lanes is dangerous and is not advisable although not disallowed. A double solid yellow line along the curb means that a specific waiting time by the side of the road is allowed, but parking and leaving is not allowed.

    Double yellow solid and broken line: This is a kind of double meridian line found in the middle between two lanes with one line solid and one broken. It means that drivers on the side of the solid line are disallowed from changing lanes or overtaking, but drivers on the side of the broken line are allowed switching lanes and overtaking.

    A group of reinforced bars, parallelly set to each other to act as a unit should be limited four in a bundle used as reinforcement in reinforced concrete, enclosed by stirrups or ties. Bars greater than 32mm should not be bundled in beams.

    The development length of every bar of bundled bars should be that for the individual bar, increased by 10 % for two bars in contact, 20 % for three bars in contact, and 33 % for four bars in contact.
