    DEFINITION

    The prime system for moving water from the atmosphere to the surface of the earth is precipitation. At the point when the mists meet cool air above land, precipitation, like rain, sleet, or snow, is activated and water comes back to the land (or ocean). An extent of atmospheric precipitation dissipates.

    Substantial precipitation happens close to the equator and diminishes with the increase in the latitude, for example, Towards polar locations. The primary source of moisture for ppt is dissipation from the seas. In this way, ppt will, in general, be heavier close to coastlines. Since the lifting of air masses is the reason for practically all ppt, the amount and recurrence of rain is generally more prominent on the windward side of the mountain as the downslope movement of air brings about to perish in stickiness, in this way, the contrary sides of hindrances as a rule experience generally light ppt. A high measure of ppt is accounted for at higher rises.

    A clayey soil generally has a low CBR value (less than 8). Sands are more granular and drain better and will generally have CBR values between 15 and 35. Gravel will have the best CBR values, generally 25 and up. That is why it is suggested to save the best material to cap the subgrade.

    • Actually, the DPC test requires less time to perform as compared to CBR test
    • In the DPC test, no need for sample preparation, since it is directly done on the ground
    • DPC test is very simple and quick as compare to CBR test
    • More skill is required to perform the CBR test
    • The instrument handling is very simple and easy in DPC test
    • CBR test is conducted on material collected from the site
    • Equipment of CBR test is more complex
    • CBR test requires more time to give result

    It is otherwise called “Concealed Beam”.

    The Hidden beam is a way to depict the load scattering on to supporting slab.

    Hidden beams are for the most part embedded inside the suspended slabs where section thickness is extensive.

    In the event that the cantilever beam is with a Hidden beam, it can not go about as an unadulterated beam and will just circulate the loads over the slab area and it can not be considered as basically bolstered one.

    – as it were, “The hidden beam isn’t a beam and the main way to spread the focused loads of the walls on the piece region. The Hidden beam is a virtual beam that was started by somebody to utilize the Beam free headroom.

    *Hidden beam is given among living and feasting spaces right angle to one another. This gives a perfect and level roof surface that is useful for the look.

    Basically it makes a spanning issue, as spans for structural help are at a right angle to one another. This implies one slab structurally basically rests over the other.

    Concealed beam between balcony and room is normal to encourage simple consideration of the gallery into room space later.

    Purpose

    To scatter loads on supporting slabs.
    To break a wide board of slab to a significant size.
    To accomplish max floor height.
    To make room for electro mech ventilation work.
    To improve architectural aesthetic appearance by giving flawless and leveled ceiling surface

    Advantages

    It saves floor height clearance.
    It permits if brickwork to be built over a slab.
    It is economical
    It gives the better interior appearance

    Disadvantages

    The disservice of the concealed beam is that it’s extensively low malleability in view of the height reinforcement proportion that is given to repay to depth limitation explicitly at column connection.

    Fundamentally it makes a traversing issue, as spans for structural support are in a correct right to one another. This implies one slab fundamentally rests over the other.

    Causes of honeycombing in the column:

    1. Improper mixing ratio
    2. Vibrating not done properly
    3. Use of excessive stiff concrete.
    4. Use of figure size of aggregate in concrete during mixing.
    5. Curing not done properly

    Following are the remedies of honeycombing in the column:

    1. the spacing of reinforcement should be maintained properly so that the vibrating needle goes middle in of the column and operating properly. If the spacing of reinforcement and stirrups is less, this illustrates the vibrating operations.
    2. In a column, strictly use of less than 20 mm aggregate used to reduce honeycombing defects.
    3. Tapping the shuttering with the help of wooden hammer during concreting this helps for minimising the honeycomb being up to great extent.
    4. Use of a thinner needle, it may be less than 25 mm. This allows vibrating at in very less space in the column.

    Hope this helps.

    Lumpsum

    A lumpsum contract (or specified total agreement) is the customary method for acquiring development and still the most well-known type of development contract. Under a singular amount contract, a solitary ‘single amount’ cost for all the works has concurred before the works start. This is commonly fitting where the venture is very much characterized, when tenders are looked for, and noteworthy changes to necessities are impossible. This implies the temporary worker can precisely value the works they are being approached to complete. Lumpsum contracts may be less suitable where speed is significant, or where the idea of the works isn’t very much characterized. Different types of agreement that may be increasingly suitable in such conditions incorporate estimation contracts (utilized where the works can be depicted in sensible detail, yet the sum can’t), cost repayment contracts (utilized where the idea of the works can’t be appropriately characterized at the beginning, frequently utilized where a prompt beginning nearby is required), target cost contracts, etc.

    Focal points of lumpsum contracts:

    • Customer’s hazard is insignificant.
    • Less varieties.
    • The customer can orchestrate capital as indicated by the installment plan.
    • Temporary worker’s income is unsurprising.
    • The offering procedure is increasingly straightforward and unprejudiced.

    Impediments of lumpsum contracts:

    • Contractual workers chance is high (helpless profitability and bungle can lead the undertaking into a misfortune).
    • Helpless subtleties and specs in the structure can prompt venture debates.
    • Deferrals in the customer’s financing can postpone the undertaking.
    • The structure ought to be finished and accessible before the pre-contract process.
    • Obtainment times can be long.

    Provisional Sum

    The term ‘provisional sum’ is commonly surely known in the development business. It is utilized in valuing development agreements to allude either to work which is really temporary, as in it could conceivably be done by any means, or to work whose substance is unclear, with the goal that the gatherings choose not to attempt to value it precisely when they go into their agreement. A provisional sum is typically included as a round figure surmise. It is incorporated scientifically in the first agreement cost; however, the gatherings don’t anticipate that the underlying round figure should be paid without modification. The agreement normally gives explicitly how it is to be managed. A typical statement in substance accommodates the temporary whole to be discarded, and a fitting valuation of the work really did to be fill in for it. In this general sense, the term ‘temporary aggregate’ is near a term of workmanship, yet its exact significance and impact rely upon the conditions of the individual agreement.

    Traverse surveying is a method to establish control networks. Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point.

    There are two types of traverse surveying , they are:

    1. Closed traverse: When the lines form a circuit that ends at the starting point, it is known as a closed traverse.

    2. Open traverse: When the lines form a circuit ends elsewhere except the starting point, it is said to be an open traverse.

    So, for the construction of road projects open traverse is used because in this we can extend roads for infinite distances.

    Defect Liability period is a particular amount of time given to the contractor after the completion of a project to check if the project is delivered in good shape, whereby if any defects be detected, the contractor is to fix the defect for free during the defect liability period.
