Repairing an Old Rotting Antique Door and Repairing a 14″ crack brick wall | Building Construction
In this article, I have mentioned two cases where the remedy for their repair is briefly explained. This sounds very easy but I am sure it will be of good help to all the Architecture and Civil Engineering students…
How would you restore an old rotting antique door?
The dimensions of the antique door are 7’x4’.
The rotting part of the door is to be cut carefully.
And the cut part of the door is replaced by the similar variety of wood.
After replacing the wood, give a similar finish to the door.

Method of Luppm Finish and Cleaning of pinhead glass | Building Construction
This is a simple article which deals with two different topics explained in a very brief manner. I hope it will be helpful to the students of architecture and Engineering….
How would you clean a 3mm pinhead glass?
Usually, a chemical called as “aerosols” are used for cleaning 3mm pinhead glass.
The welded design on the pinhead glass can be made plain with the help of some chemical powder and then rubbing the glass with a sandpaper.
How would you luppm finish on an already painted wall?
Oil paint + whiting powder= luppm paste is made.
The paint and plaster of the already painted wall is scraped out.
Then the wall is made rough by chiselling or the wall is brushed by a “wire brush” that makes the wall rough.

Types of Measurements in Surveying | Civil Engineering

Types of Measurements in Surveying
Surveying is the art of making suitable measurements in horizontal or vertical planes. This is one of the important subjects of civil engineering. Without taking a survey of the plot where the construction is to be carried out, the work cannot begin.
From the above definition, we conclude on two types of measurements in surveying. They are as follows:
- Linear measurements
- Angular measurements
Now we will go on with the discussion of each of these types of measurements along with their subtypes.
Linear measurements are further classified as follows:
Horizontal Distance
Vertical Distance
Horizontal Distance
A horizontal distance is measured in horizontal plane if a distance is measured along a slope, it is reduced to its horizontal equivalent.
Horizontal Angle
Vertical Distance
A vertical distance is measured along the direction of gravity at that point. The vertical distance are measured to determine difference in elevations in various points.

Purpose of Surveying | Civil Engineering
Posted by BenzuJK in Surveying and Levelling on December 16, 2010
Purpose of Surveying in the field of Civil Engineering
- To determine the relative positions of the existing futures of the ground.
- To layout our marked positions of proposed structures on the ground.
Surveying | Land Survey
- To determine areas, volumes and other related quantities.
- To prepare a map of a country of detailed out location of cities, towns, villages and major roads.
- To prepare the engineering detailed plans and sections of various sections such as roads, railways, bridges, dams and other structure.
- To prepare a topographical map showing details of hills, valleys and rivers.

Surveying is the art of making suitable measurements in horizontal or vertical planes. This is one of the important subjects of civil engineering. Without taking a survey of the plot where the construction is to be carried out, the work cannot begin.

Levelling
Levelling is the art of representing relative positions in the vertical plane of different points on the earth’s surface.
It helps in determining the areas that are to be levelled to achieve a certain slope.
Principles of Surveying
All the surveys that are conducted are based on two fundamental principles. They are as follows:
- Working from whole to part
- Fixing a point with reference to two fixed points
Working from whole to part
In order to localize errors and prevent their accumulation, a set of control points is always established with great precision first for the whole area to be surveyed.
Later on, details or filled in between these control points to a relatively smaller precision.
This fundamental work principle is known as “Working from whole to part”.
Fixing a point with reference to two fixed points
Survey stations are fixed by atleast two measurements, either both linear or angular measurements or linear and angular measurements from two control points.

The Art and Science of Structural Design Engineering
Posted by BenzuJK in Civil Projects on April 25, 2010
The practice of Civil Engineering is extremely diverse, involving technical, legal, business & practical skills. It consists of various specializations like Structural Engineering, Project Management, Geotechnical Engineering and Surveying. The ability to combine skills in all these areas will contribute significantly to the success of a civil engineer.

To provide an overview of factors which are relevant to the successful practice of structural engineering, we have to look at the role of a structural engineer, understanding the needs and objectives of a client, the difficulties and conditions faced on site and the constraints put down by the Architect. A structural designer is capable of calculating different loads and stresses acting on a structure and designing the structure to resist there forces. For tall buildings, towers, tunnels, roads, marine structures, bridges and even space stations, structural designers are called upon to provide their expertise to ensure the stability of the structures.
