    This is one of the most popular questions.

    Basically, building codes typically require that the structure is wall roof floor, the roof is fire-resistant.

    The standards set forth by the International Building Code (IBC). fire resistant Wallis designed for a definite time period.

    According to ‘Commercial drafting and detailing book’, a one of our fire rated wall consists  2 x 4 studs spaced 16 inches from the centre of one stud to the centre of the next.

    It is necessary to check the nature of the soil before you build your dream home. The ground where you are wanting to build your dream home, it is necessary to check the soil nature of it before starting construction work.

    Soil testing is first done to test the bearing capacity of the soil. The physical and chemical configuration of the soil is checked during this process. The soil must be able to withstand the load of the structure. The nature of soil decides the bearing limit as well as guarantees to decide the structural adjustment. The nature of soil relies on different factors, for example, climate, environmental change and for as far back as years the land was sent for what reason and what was there before.

    The length and depth of the footing are decided during the foundation relying on the nature of the soil. The water level of the soil can only be resolved from soil testing. In light of the soil testing results, the nature of the material can be chosen. For instance, because of dampness the zone is lead to corrosion, at that point it is essential to pick just corrosion safe TMT Bars for the construction.

    A soil test is a very significant step in construction before it starts. If the soil testing isn’t done, at that point the structure will be presented to various failures and the final result could be lethal.

    Types of Soil Testing for Construction

    Gravity Test

    Moisture Test

    Atterberg Limits Test

    • Liquid Limit
    • Plastic Limit
    • Shrinkage Limit

    Dry Density Test

    • Core Cutter Method
    • Sand Replacement Method

    Proctor’s Compaction Test

    Difference between granular sub-base and wet mix macadam in payment structure:

    The wet mix macadam mostly consists of laying spreading and compacting of clean, crushed, well-graded granular material that is prepared and approved granular sub-base.

    Single compacted wet mix macadam player shall not be less than 75mm.

    Whenever we are using vibrating compacting equipment then compacted depth of a single layer of the course of the subway may be up to 200 mm.

    Wet mix macadam shall be prepared in an approved of water macadam mixing plant.

    Here replacing the aggregate fraction should be retained on 22.4 mm sieve with materials of passing from 22.4 and written on 4.75 mm.

    While the addition of water, the evaporation loss shall be considered the mixed material shall be uniformly wet and segregation will take place.

    • Height of Instrument :

    It is the method which deals with the obtaining of RL of the line of collimation by adding BS reading of a known RL point. Thus, RL of the line of collimation is called the Height of Instrument. It is always measured from the benchmark. Hence the benchmark is the point on the sea derived from mean sea level.

    – method to calculate RL;

    height of collimation (H of C) = reduced level(R.L.) + backsight (B.S.)

    reduced level (R.L.) = height of collimation (H of C) – foresight (F.S.)

    reduced level (R.L.) = height of collimation (H of C) – intermediate sight (I.S.)

     

    • Rise & fall method :

    It is the method which gives the difference of elevation between consecutive points by comparing each point after the first that immediately preceding it. Rise and fall are indicated by the difference in staff reading. After that RL is found by adding the rise to or subtracting the fall from the reduced level of the preceding point.

    – method to calculate RL;

    fall (F) = foresight (F.S.) – backsight (B.S.)

    fall (F) = intermediate sight (I.S.) – backsight (B.S.)

    rise (R) = backsight (B.S.) – foresight (F.S.)

    reduced level (R.L.) = precede reduced level  + rise (R)

    reduced level (R.L.) = precede reduce level – fall (F)

    Aditya,

    Here you are asking about Life Cycle Assessment (LCA) of structure.

    The life span of structure will vary according to the type of structure.

    There is no formula available to calculate the life span of any structure.

    Different parameters we should take into mind while doing a calculation of life span of structure, they are as follows;

    Building Construction Material:

    • RCC structure

    Structural Design:

    • Mostly influencing parameter.
    • Vary as per Building Construction Material.

    The locality of structure construction: E

    • Earthquake-prone area
    • HFL (High Flood Level) zone

    Height of structure.


     Kindly noted that I have attached one photo of the life span of various structures.

    https://theconstructor.org/building/rooms-minimum-height-size-standards/5116/

     

    The ceiling height of public and industrial buildings are larger than residential buildings, due to various reasons like the people traffic, ventilation purposes and for easy operation in case of industries.

    The minimum height of public buildings and industrial buildings is 3.6m.
