🏠How to protect the building from chemical and environmental attack?🏗

 Welcome back friends, 

          If one question is blinking in your mind that is "Even after great technologies and experts are available Special care is being taken during construction activity then "why the structures get deteriorate?"

        If this question is blinking in your mind then you are on the right way of thinking as an  engineer and quality construction seeker.

       Most of the structural elements in the  vorious type of Construction activity loose their Strength due to environmental & chemical and environmental factors. In Simple word "Chemical and environmental attacks". 

Now you will ask How'?

         We all know that due to Industrialization various industries produces  huge amount of waste in the Gas, liquid and Solid form. This waste directly and  indirectly present in our environment and here the actual Chemical & environmental attack Starts.

         So many process are involved in the process of chemical attack but I will explain here basic concept of chemical attack that is crystalization.

         Chemicals like sulfate present in environment enter into concrete from pores or voids present in the surface of concrete and this chemical entrapped into internal voids .

         As the time passes this entrapped chemical starts preparing Crystal and this Crystal then develop pressure internally on concrete. As a result we see the cracks on the concrete and this process not happen only in concrete but also in various construction materials by the means of various chemicals and by various ways.

        In advance construction practice construction professionals use various surface treatment like chemical coating on surface of building elements to avoid this future unseen Risk of cracking in the structure.

      As a effective solution of this Chemical and environmental attack. We will discuss here about  Solvent based Coal epoxy Coating system.

It is popularly known as AC-DUR-CT ('s) 

It is two Component Solvent based Coal tar epoxy system.

Introduction to physics 📔Physics means?📔

      So many my dear friends think that Physics, mathematics and other subjects are so much difficult and to learn this subject we need to do so many efforts, but it's not totally true any subject in education is very much simple you just need to OBSERVE THAT SUBJECT CLEARLY. You will find that subject like your daily playing games.

Here it is *Introduction to physics* 

  Science has many subjects like physics, mathematics, chemistry, biology, other subjects etc. Let us now understand the subject of 'Physics' through some daily activities. # physics subject #

        Physics is something that happens but we can't see it. That is, we hear sound but cannot see sound waves, we see that magnets are attracted to each other but we cannot see that magnetic attraction. In physics we study the natural laws, like an apple falls to the ground and our great scientist see it and we find a discovery called gravity. I mean, we see the apple falling down but we don't see the force of gravity.

        Some important points and their example are mentioned below. I hope you understand that easily. We see these example in our daily life.

You will get here # Scope and excitement of physics #

1) Physics teach us law of nature, if we observe natural activities then definitely we understand the physics. So we starts from our scheduled day. At the morning our alarm ringing and we listen this sounds ultimately we wake up at the early morning. So here main point is ' Sound ' which included into the physics subject. These sounds create some sound waves which we listen.

                       # Ambitious #

2) So after, at the morning we go for make a tea, for that we boil water. When we observe that hot water creates steam or vapours. So here is main point is Heat. It is also the part of physics. Means heat was dissipated from the water in the form of vapour or steam. These steam we use in many places that is we use it for generating power (For example- electric power, etc) through turbines at a power stations.

3)So now the office time, we take a cars key and go outside. We pull the door of car and seat inside. So here we pull the door means we apply some force to pull the door. The main point is Force. Another example when the car's wheel rotates, their is grip between tyre and the road. That grip create some force, although we stop the car and it slips little bit means we feel some Friction that id also example of force. I hope all understood the force concept.

4) Now we work on the computer. Hence first of all we switch on the button. we give electricity to any device like at current situation we see our mobile / PC etc. It requires electricity , so the these electric or electronic devices are also works on principles of the physics i.e. Electrical Energy . 

         Hey it's evening coffee time, after sunset we switch on the light. The Light is also the part of physics , we see reflection / deflection of light. Yes it is physics.

        So we see some point's i.e. Sound, Heat, Force, Friction, Electricity, Light .

        Physics also includes magnetism, gravity, inertia, etc. I hope you all understand the above points which we experiences in our daily life.

Labour productivity for different Items of construction work.

 Hii engineers, 

In this blog we are going to see, what is the labour productivity for different items of construction work.

First see labour productivity is the amount of work can be done by a worker in 8 working hours and this values are finalized by government authority.

The labour productivity can be vary according to location of site, site condition and various climatic conditions.

Let's start,

1. Excavation in foundation tranches in soft soil, lead up to 50m and lift up to 1.5m.                         [ 2.27 m3 / mazdoor ]

2. Excavation in foundation tranches in hard soil, lead up to 50m and lift up to 1.5m.                         [ 2.10 m3 / mazdoor ]

3. Excavation in soft and decomposed rock by blasting, lead up to 50m and lift up to 1.5m.         [ 0.55 m3 / mazdoor ]

4. Sand filling in plinth, consolidating and dressing.             [ 4.0 m3 / mazdoor ]

5. Single layer brick flat soling including ramming and dressing the bed etc.                        [ 9 sq. m / mazdoor ]

6.Lime concrete in foundation.                                [ 10 m3 / mason ] 

7. Cement concrete.   [ 5.0 m3 / mason ]

8. Cement concrete ( 1 : 2 : 4 ) for R.C.C work.     [ 3.25 m3 / mason ]

9. Brickwork in foundation and plinth.                   [ 1.25 m3 / mason ]

10. Brickwork in super structure ground floor.      [ 1.10 m3 / mason ]

Can a builder sell parking ..?

          For Marathi translation of this blog 👉https://engineerpravinkadam.blogspot.com/2020/11/blog-post.html

   'Parking' is an intimate subject when buying a flat in the society.  There are many misconceptions about whether a builder can sell a flat as well as a parking lot.  Let's take a brief look at the legal information about this.  Let us briefly look at the legal information about this.

 Two types of parking are generally recognized by law. 

 1.  Common / open parking and stealth parking  and

  2.  Covered / Garage Parking .

 👉 The Maharashtra Ownership Flats Act (MOFA) 1963 and the recently passed Rera Act discuss the duties, responsibilities and rights of builder-promoters and the rights of flat customers.  It also includes common space, amenities.  Although the Rera Act has been passed, the Mofa Act has not been repealed by it and the provisions of the Mofa Act apply as long as they do not go against the Rera Act.

 The Development Control Rules approved by the Government have been implemented by the Pune Municipal Corporation and are subject to change from time to time.  According to this regulation, according to the number of flats, the calculation of how much parking should be provided for bicycles, two-wheelers and four-wheelers is given.  According to this calculation, the construction plan of the building is not approved by the municipality without giving information about how much parking has been provided in the respective building.  That is why parking is mandatory in every multi-storey building.

 👉 Common / open parking and stealth parking cannot be sold to builder 

 In the past, it was the responsibility of the builder to mention in the advertisement what the common areas and facilities would be like under the Mofa Act.  Section 2 (n) of the RERA Act now gives a clear list of common areas and facilities, while subsection (iii) clearly mentions base parking, terraces, parks, play areas as well as open parking in common facilities.  Is.  This open parking also includes "stealth parking".  In fact, its meaning is hidden in the name "Common". An important decision on this question was taken by Hon'ble Supreme Court, "Nahalchand Lalunchand Pvt.  Ltd.  Virudh Panchali Co.Op.  Society (A.I.R. 2010 SC 3607) ', it is still applicable today.

 In this case, Hon.  While upholding the judgment of the Mumbai High Court, Hon.  The Supreme Court noted that common or open parking does not fit the definition of "flat" in some MoFA laws and therefore the builder has no right to sell it.  Similarly, the builder does not have the right to sell "stealth" parking as a garage;  When selling a flat, the common area payments are taken by the builder from each flat holder in proportion to the carpet area of ​​the flat, so there is no financial loss to the builder.  The Supreme Court has ruled.  Therefore, such open or stealth parking cannot be sold to the builder, as its use is common.  Similarly, after the completion of the construction of the building, the builder is bound to make a purchase deed of both the land and the building on it in the name of the society.  That is why such open space cannot be sold to the builder as a flat holder as parking.

 👉 Covered / Garage parking can be sold to builder 

 "A parking space in a building that is enclosed by a wall on all three sides and has a roof above, but does not include an enclosed parking space such as an open parking lot" is defined as "garage" under Section 2 (y) of the Rera Act.  This is what we call 'covered parking' in practical terms.  However, the definition of covered parking under RERA Rules 2 (j) is slightly different from that of closed or covered parking spaces approved as per the construction regulations.  This includes "mechanized parking" currently available.  F. published on the web site of Maharashtra.  A.  In response to Q (Frequently Asked Questions) No. 9, common parking cannot be sold in reply, but it is mentioned that 'covered parking' can be sold as mentioned in Rule 2 (j).  Similarly, if you look at the draft agreement given in the Rera Act, it also shows that covered parking can be sold, but its price has to be shown separately from the price of the flat.  There have also been cases of some members creating their own 'covered' parking lots by putting iron grills against the approved map in the open common parking lot, but this is not expected by law.

   👉Society and parking 

 Society by Lodge no.  The General Body has the power to decide on parking rules, parking fees, etc. as per 72-84 parking.  This is the subject of a separate article.

We briefly explained where parking can be sold or not by law.  But whether any law applies depends on the background of the case.  Although the law is in place, it is still limited given the number of vehicles available.

  There is no space for car parking at home or at work, so many people are now considering options like Ola-Uber.  Suppose the issue of covered parking is resolved, but there is a lot of debate in societies over common parking, and in such cases, first-come, first-served, lottery-fixing and annual slots are decided by by-laws.  In this way, it is more appropriate for everyone to discriminate.
