💡TIPS FOR SAVING TIME & 💰MONEY DURING CONSTRUCTION 🕐 Part 1

Welcome back friends,

We all know that house construction is the very much interesting and important topic of everyone's life, or we can also say like it is the very much important dream in every ones life.

House construction is also a time consuming or huge investment task some time or if we don't have as much required knowledge about it,

so today we are going to discuss about some basic and important tips that we can use during house construction to save our valuable time and money.

So lets start,

👉Understand the present and future needs of your family.

Generally house is the place where we spend most of the important and pretty time with our family. Means our family is the prime user of the house so before planning any house we must consider present or future needs of our family, means if a family having two Childs so as per the future requirements we need to design our house with two seprate rooms for each of them.

👉Ensure that the construction plan, working drawings and the estimated costs are in place before starting construction.

"A good start and a good end is most important" so before starting any construction activity we must have proper plan of building in hand with all the required drawings and a faire estimated cost, because we generally observe that many house constructions stop suddenly or go slower than their scheduled time due to some any changes in drawing or facing financial problems. so before starting actual activity we need to sort out this all issues as much as possible.

👉Use local available materials.

Transportation is being very much expensive now a days so we can save lots of money by using locally available materials. if we use locally available material we can order it at any time and within very much short duration it can arrive at our construction site hence we can reduce chances of stopping work due to material shortage.

👉Make sure there is maximum natural light and air in all rooms By providing proper ventilation and windows.

Not all the time artificial light or brightness is good Sometimes natural light play very good role in respect with artificial light. Natural light kills some types of bacteria and prevents fungi production due to moisture. Here is very major role is of your engineer because he can decide where and how much windows are required. Windows and doors are also need to design by considering function of room.

🏠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.

For details about this company 👇👇

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 #

Contact -99603 88813/ 88887 40091

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.

permeability of soil

What is permeability?

" Permeability is defined as the property of a porouse material which permits the passage of water or other fluids thorough it's interconnecting voids. "
A material having the continuous voids is called permeable. Gravels are highly permeable while stiff Clay is the least permeable, and hence such a Clay may be termed impermeable for all purpose.

Types of flow through soils =
1. Laminar flow .
2. Turbulent flow.
In laminar flow , each fluid particle travels along a definite path which never crosses the path of any other particle .
In turbulent flow , the paths are irregular and twisting, crossing and recrossing of each particle is occures.

Some important fields where permeability and seepage study is very essential . Out of which some are below.

1. In case of saturated compressible soil to determine the rate of settlement of foundation of any structural element.
2. To calculate the seepage of water through the body of Earth dam , and stability of slopes .
3. In calculation of uplift pressure under hydraulic structure and their safety against different water pressures .
4. Ground water flow towards open well and tube well and drainage of soil in diff conditions.
