Causes of Air Pollution - PR

Image
   Causes of Air Pollution What Is Air Pollution? The release of pollutants into the atmosphere is defined as air pollution—pollutants that are harmful to human health and the environment. Each year, air pollution kills nearly seven million people worldwide, according to the World Health Organization (WHO). There are various causes of air pollution. When solid and liquid particles, known as aerosols and certain gases, end up in our atmosphere, they cause air pollution. Because these particles and gases can be harmful to the environment and our health, it is critical to keep track of them. Breathing fresh and clean air has become nearly impossible due to increasing air pollutants. Everyone is concerned about their health because of the causes of air pollution. Air Pollutants Air pollutants are classified into two types: Primary Pollutants Primary pollutants are those that contribute directly to air pollution. Sulfur dioxide, emitted by factories, is a primary pollutant. Seconda...

CONCEPTS OF SINGLE PLANE METHOD

Image
    The "Single Plane Method" is primarily used in surveying for  trigonometric levelling  to determine the elevation of an inaccessible object, like a building's top. It involves setting up a theodolite at two points on the ground, measuring the angle of elevation to the object from both points, and taking staff readings at each station. By using the observed angles, the known horizontal distance between the stations, and the staff readings, trigonometric calculations are used to find the object's horizontal distance and height.  Key Concepts & Procedure  1.      Triangulation/Same Plane Assumption:   The core idea is that the two instrument stations and the object are in the same vertical plane. 2.      Measurements: ·         Station 1 (A):  Set up the theodolite, ensure it's level, and record the staff reading (S1) for the line of sight ...

CALCULATION OF COST FOR BRICK WORK AND PLASTERING FOR 4M X 3 M ROOM

Image
  Estimate the quantities of brickwork and plastering required in a wall 4 m long, 3 m high and 30 cm thick. Calculate also the cost if the rate of brickwork is Rs.320.00 per cu.m and of plastering is Rs.8.50 per sq.m. Solution: Quantity of brickwork = L x B x H = 4 x 3 x .30 = 3.6 cu.m Quantity of plastering = 2 x L x B = 2 x 4 x 3 = 24 sq.m (Two faces) Cost of brickwork = 3.6 x 320.00 = Rs.1152.00 Cost of plastering = 24 x 8.50 = Rs.204.00 Total Cost = Rs.1152.00 + Rs.204.00 = Rs.1356.00

What Are Sewer Pipes? 7 Different Types of Sewer Pipes - PR

Image
  What Are Sewer Pipes? 7 Different Types of Sewer Pipes What Are Sewer Pipes? Sewer pipes act as a mode to dispose of waste materials. Sewer pipes are made of different materials and are available in various sizes.  The primary function of sewer pipes is to carry the sewage or wastewater from homes or commercial buildings to the drainage system to be treated or removed. The sewage pipes can be damaged or decayed with time and require repairs or replacement. Most sewer pipes are made of concrete, which is known for its durability. They are also rust-proof and usually last for 30 years or more.  Plastic pipes are more expensive, but they are also considered the future of sewer pipes. Plastic pipes are becoming more popular as they are eco-friendly and cost-effective. Here we have discussed some of the common types of these piping systems. Types Of Sewer Pipes Following are the types of sewer pipes used to carry out the solid waste, though some are currentl...

VALUATION AND ITS METHODS

Image
Valuation process  determines a property's current market value by analyzing factors like location, materials, and structure, and employing methods such as cost-based, rental, or profit-based approaches.  Common methods include the  cost method  (estimating construction cost minus depreciation), the  rental method  (based on income potential),  profit-based valuation  (for income-generating properties),  direct comparison  (comparing with similar properties), the  development method  (for new developments), and the  depreciation method  (accounting for value loss over time).    Steps in the Valuation Process Define the Purpose : Clearly establish why the valuation is needed, such as for buying/selling, taxation, loan security, or rent determination.   Gather Information : Collect details about the property, including its location, size, features, and the quality of materials used. ...

Rate analysis

Image
  Rate analysis for civil works is  the systematic process of calculating the cost per unit of a construction item by breaking it down into its constituent parts: materials, labor, equipment, overheads, and contractor profit .  This analysis provides a foundation for accurate cost estimation, bidding, project planning, and budget control by determining the most cost-effective method for completing a task and ensuring project profitability.   Key Components of Rate Analysis A thorough rate analysis for any civil work includes the following elements: Material Costs:   The purchase cost of all necessary materials, including cement, sand, aggregates, steel, bricks, etc.   Material Transportation & Handling:   Costs associated with transporting materials to the construction site.   Labor Costs:   Wages for skilled, semi-skilled, and unskilled labor required for the task, along with any associated benefits.   Machinery/Equipment Costs: ...
