What is purpose of lintel and sill level in building construction?

    Basically sill is known as the horizontal bed of the mortar which is usually as wide as the wall provided below windows or other openings. Therefore sill supports the windows. And lintel is made up of reinforced concrete or cement mortar .Therefore lintel support the wall above the openings.

    To understand the difference between tender documents and contract documents, first we have to understand what these documents contain.

    Tender Documents:

    A tender is an offer in writing to contractors to execute the some specified works or to supply specified materials within a fixed time frame and as per conditions of contract and agreement between the contractor and the owner or the department or the party.

    The tender documents contains the bill of quantities (BOQ), specifications of the works to be carried out, time frame for the completion of the work, conditions of the contract and plans and drawings. These documents are provided to the contractor on the payment of certain fees. The contractor who quotes the lowest rates for the overall works are offer the contract to execute the work.

    Contract Documents:

    Contract documents are the agreement between the owner or the party or the department and the contractor to execute the works as specified in the tender documents as per conditions of contract on the rates quoted by the contractor.

    The difference between Tender and Contract Documents:

    The difference here to be noted is that tender documents are offered to as many contractors as possible to get the lowest quotes for the work specified, while the contract documents are signed only with the contractor with lowest tender or rates.

    While the tender documents contains the conditions of contract and all the details for the specified work, there is not much difference between the two in terms of contents. But tender documents can not be submitted as Letter of Acceptance (LOA) as these are two different types of documents. While a tender document can not bind the contractor to do the work, a contract document binds the contractor to complete the work as per the agreement.

    Simple Example to understand the difference between tender and contract documents:

    When you are selected for a job in a company you are offered offer letter to join the company. But getting selected in a company does not mean that you join the same company, you may have other offer letters as well. But when you sign the letter of acceptance (LOA) for the job, you are bound to join the company. So, here offer letter from the company is a tender document and LOA is the contract document.

    Let’s discuss some important precautions that we should keep in our mind while doing hand mixing of concrete. They are as follows ;

    • Hand mixing should be used for small concrete preparation
    • Hand mixing platform should be watertight and it should be impervious
    • Mixing platform should be of concrete platform or brick floor to avoid the addition of extra water in our concrete
    • Water should be added in some interval in concrete while hand mixing
    • Avoid large sizes of buckets for the measurement purpose
    • Labours should wear a mask to avoid some respiratory diseases

    Steps to follow for doing hand mixing of concrete :

    • Doing proper batching of all the ingredients of concrete and spread them evenly
    • Add cement with Sand and mix them for throughout
    • Mixing process should continue until we get the homogeneous colour
    • Then add coarse aggregate into it and again mix it appropriately
    • For mixing forward and backward movement of shovel have to be done
    • Then at the centre, one hollow circular space is formed for the addition of water
    • While doing hand mixing 5 to 10% of the extra amount of cement should be added
    • PPE( Personal Protective Equipment) should be wear by labour while doing hand mixing

    Sir,

    All the collected data is very useful for the properties of soil gradation, density, bearing capacity, shrink and swell potential, lateral earth pressure and groundwater condition.

    Dry density is used to determine the appropriate structural design for the pool shell.

    Most critical soil property is swell potential which is highly influencing factor for structural design.

    Period of building and its relation with frequency:

      Natural period:

    • The natural period of a building is simply a time taken by it to undergo one complete cycle of oscillation.
    • The natural period is one of the properties or building which is controlled by mass and stiffness.
    • Formula to find out natural period is,

    Tn =2π√(m/k) where,

    • Tn is a natural period of building.
    • m is mass
    • k is stiffness

    Reciprocal of the natural period of a building is nothing but the natural frequency and its unit is Hertz(Hz)

    Thank you.

    Generally, Ordinary Portland cement (OPC) is used in the factories, power plants and in large construction slabs.

    Portland pozzolana cement (PPC) is used for the construction of houses, schools, and residential building slabs. PPC is cheaper than ordinary Portland cement. Thus to reduce the building making cost, PPC should be adopted.

    Both the PPC and OPC cement is used in the construction of slabs.

    Portland pozzolana cement is Better resistant to sulfate attacks. Thus PPC is used in underwater construction where water has some amount of sulfur quantity. Its setting time is higher than OPC.
