    Sir,

    HDPE liner was choosen to protect the surface and groung waters of the area and to assist with the evaporation of the water.

    This liner is also known as the HDPE goe-membrane. It contains 98% high density polyethylene.

    It is durable and long lasting and are used to line cooling ponds due to their low permeability and resistance to UV light.

    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.

    Seasoning of stone :

    Generally, the action of having various changes in different seasons on the stone which are drying and wetting of stone which gradually forms the crack in stones which leads to the action of weathering action and forms inorganic small size materials is called seasoning of stone.

    Seasoning refers to both drying and wetting cycles on one hand, and airing of stone, on the other hand. Dehydration during seasoning is more or less an irreversible process. Thus seasoning applied mainly to soft limestone; hard limestone seems to less affected by it. Stones have natural moisture, known as quarry sap. This quarry sap renders the stone blocks comparatively soft and makes them easy for working. Immediately after quarrying, a stone is soft and is easy to work with it so sized and primarily dressed, but polishing requires a fully seasoned and hardened stone.

    It has been seen that it is very difficult to adopt any new innovations in Construction Industry especially in India.

    When we talk about Construction of Residential Buildings it has been observed that the the variation in cost could be matter a lot. When final estimation sanctioned and at the time of execution it seen that 3 factors affect this capital :

    1. MATERIAL ( Variation of cost would be 55 to 65%)
    2. MANPOWER ( Variation of cost would be 25 to 35%)
    3. EQUIPMENT ( Variation of cost would be 10 to 15%)

    Note: Above is the condition in case of Residential Buildings only.

    This suggests that every project needs a Good Decision.

    Suppose, if you have :

    1. Sufficient Captial for Project.
    2. Sufficient Space for equipments etc.
    3. But there is Time constraints.

    Now the Question is what method of formwork Do You Use? To complete your project.

    Now a days less number of companies Using Mivan Formwork. It comes from Malaysian Company.

    Is this Case we can use this method. This is method you can cast one floor at a time as single unit. Less thickness of Concrete wall made that increases the carpet area. It is made of Aluminum so obviously it is less weight and easy to handle and in this method there is no wastage of materials, this formwork made a air tight casement so no league of concrete is possible.

    So, what i thought, in India, near in 2 to 3 years every company will adopt this technique.

    Edit 1: Someone are thinking that it a Old technique. My simple Question is that Is there any company in India presently using Robotic Technology or Nano Technology ? As both are invented before independence only. Just read my first sentence of this answer and comment accordingly.

    Edit 2: Just think Which formwork is best and why? If you have 3 options Timber Formwork, Steel Formwork and Aluminum Formwork. Now, when i said Aluminum Formwork, so is it that Aluminum Formwork is nothing but Mivan Formwork?

    Note: Every Mivan is a Aluminum formwork but every Aluminum Formwork is not Mivan.


    Right from Rotating towers (Dynamic tower-Bubai) to self reparing roads (in a villageIndia-Developed by ) Hyperloop there are many innovations coming up day by day.

    As many friends have discussed few topics above. I would like to share what latest technologies / innovations being implemented in my surroundings.

    As a part of Junctions development few grade seperateors are proposed in Hyderabad city.

    Construction methodology followed at one of the locations is first of its kind in Hyderabad .

    Only the foundations are cast-in-suit and rest all are brought – placed & pre stressed in stages for speed up in construction .

    At few other places steel piers and girders are proposed.

    => Precast building construction is growing up rapidly.

    => Box pushing methods for underpass / RUB

    construction .

    => Aerocon ACC blocks -super strong & light weight for fast and easy construction used by many developers.

    These are few things on construction side.

    Coming to software’s with latest technologies/Innovations in Civil 3D …etc..

    All the designs i.e. alignment design , structure design etc…can be done in one go as per exactly integration with Google maps.

    What ever latest technologies/innovations came or coming. Olden techniques are always mind grabbing and beyond the imaginations.

    Civil engineering rocks…

    1. New Emergent Materials. These materials can be “grown” as opposed to built. They posses properties that react to certain to certain conditions that make them change. While some of these are still in very early development and others not yet in production, when they do become available, how will our industry change when a structure can grow itself with pre programmed instructions for perfect engineering.

    2. Generative Design- the ability of a computer to create an architectural or engineering design without Human Intervention. Its “fed” data from 1000s of previous design projects and uses that to optomize and create “its” own.

    3. Laser Scanning Point Clouds- A laser or a multiple photographs is used to create a 3D mapp of a structure or surface. This blows away traditional surveying.

    4. 3D Printing- Additive Manufacturing that produces products by extruding material layer by layer. Entire buildings have been produced this way.

    5. Robotic Prefabrication- Robots enable the production of a structures parts in pieces within controlled enviorment factories. Components are produced and assembled and than delivered on the sight for drop in place finish. This dramatically reduces labor and schedule.

    As far as what they do there is no difference, and both support weight loading above them. Shape wise a lintel is usually flat compared to the curved shape of an arch. Strength wise the arch is far superior and only compresses more the greater the loading, compared with a lintel that has limitations to what it will hold before failing due to compression.

    Having said that most lintels carry very little weight anyway as it is spread out through the interlocking of stone, block, or brick and the only weight it actually carries can be measured by drawing a line at 45° from each end of the lintel until they cross in the centre above it and what its actual loading is. Beyond that, the wall supports its own weight and that above it providing something supports the interlocking material and how the Victorians managed to support mass weight purely on timber lintels only 3 inches thick. With lintels, span becomes an issue very quickly much less so with an arch

    Capital costs are fixed, one time expenses incurred on the purchase of land, buildings, construction and equipment used in the production of goods or in the rendering of services. In other words it is the total cost needed to bring a project to a commercially operable status.
