    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.

    Why Install it in the slab? A solar panel is not a load bearing structure. You cannot use it for structural purposes. That is simply a bad decision because solar panels are costly and hence they need to be kept safe from damage. We can install them above the slab though if we wish to.

    But again, slabs are horizontal and it’s foolish to install a horizontal solar panel. You’ll never see it that way anywhere except for at the equator. That is because sunlight mostly falls at a slant and to grab maximum intensity, the solar panel has to be perpendicular to the sun rays which will never be horizontal. Beyond the tropics, sunlight will never fall vertical ever in a year. So, no chance of installing a solar panel in the slab. Only if there’s a non load bearing slab cast to hold the solar panel, then it might be possible but that too is a bad idea because it will unnecessarily add to building cost, time and weight.

    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.

    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.

    Slopes in pipes and drains are decided by quantity of water or wastewater to be transported through it by the action of gravity in cumecs. Following things influence the slopes of drains and pipes:

    1. Quantity of water to be transported

    2. Size or diameter of the pipe

    3. Distance the water to be carried

    4. Velocity or the pressure required for the water at the outlet, if any

    Slopes of drains and pipes at construction site is checked by dumpy level or level machines. For the same, you have to calculate depth of pipes at different intervals.

    Suppose, 1:4 slope of the pipe is required as per drawing (as mentioned by you), then the depth of pipe at should have a difference of 1 m from start of the pipe to the end of pipe at 4m. If you want to know the depth of pipe at 2m length, then it will be half of the end position, i.e. 0.5m. These are calculated based on triangle.

    Slopes are always mentioned w.r.t. a reference point. Consider your reference point as a levelled surface. Then length of the pipe required will be length of the triangle, base will be the depth required from the start to end of the pipe. Now you can divide the triangle at different point and calculate the depth required at different locations of the pipeline or drain system.

    I will provide your more details with figures soon.

    Rebate is a top edge cut on the stone so that it does not allow the rainwater to penetrate inside the stone mortar or joint and flows quickly from the horizontal surface of stone masonry.

    Throating is a groove provided inside the cornice, sill, and coping to prevent water flows with the wall surface and allows it to discharge away from the wall surface. It protects walls from the impact of rainwater.

    Chases is a stones course provided at the top of the wall. It also protects from rainwater. It is generally constructed in an ornamental design.

    Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement.

    The general range for CBR is 2% to 14% or 15%. If it is found below 6%, then the code specifies some necessary subgrade improvement before laying the concrete slab directly over it.

    Also, the CBR could be increased up to say 40% or 50% by ground improvement, and still, the subgrade may be fit for rigid pavements.
