Chapter 2 - Different Types of Estimates In our earlier article, i.e. Chapter 1 – Basic Introduction to Estimating and Quantity Surveying , we have learned about the basics of Estimates and Quantity Surveying. Now, in this article, we will be going to learn about the different types of estimates that are used to carry out the estimates in this field of Civil Engineering. Follow the article to learn more about the types of estimates, Types of Estimates Detailed estimate or Item Rate estimate or Intensive estimate. A detailed estimate is a precise estimate that is created in two steps. The first stage involves accurately extracting the measurements of each item from the drawings and computing the amounts beneath each item. The cost of each piece of work is determined in the second step, and the overall cost is computed by adding all of the expenses together. A percentage of the projected cost is added to account for those things that do not fall under any of the other headings, as well

Chapter 1 - Introduction to estimating and Surveying by EngineersIndia Introduction to Estimating Estimating may be described as a prediction of the likely cost of a construction or a project before the work begins. It takes talent, experience, foresight, and excellent judgment on the side of the estimator, as well as a thorough understanding of the materials and labor costs involved in the project. If labor and material costs stay constant, a reasonable estimate should not deviate by more than 15% from the actual cost of the project after completion. Guesswork entails making a random decision based on all relevant information. It may result in a figure that is either too high or too low. Estimating aids in the alteration or modification of a project to fit inside a budget. It is helpful in preparing tenders for construction projects and inspecting the work done by contractors for interim and final payments. It also serves as a foundation for determining the regular rent for buildi

BOGUES COMPOUNDS Taken from the notes of Common Building Materials. Define Bogues Compounds As all the above-mentioned cement materials mentioned in the "Building Material and Construction (BMC)" are intergraded and burned, they combine to create a complex chemical compound known as BOGUES COMPOUNDS, which is responsible for the cement’s properties Bogues Compounds Tri Calcium Aluminate [3CaO.Al2O3].[Celite].[C3A] - 7% to 14% Thanks, Kumar Bhanushali

Chemical Characteristics of Drinking Water Chemical Characteristics H2O is the chemical formula for water. Water's capacity to "stick" to itself and other surfaces is due to its unusual form, which has both hydrogen atoms on the same side of the oxygen atom. The hydrogen atoms provide a positive electrical charge, whereas the oxygen atom produces a negative electrical charge. Total Dissolved Solids (<500) Total solids can be found by evaporating a sample of water and weighing the dry residue left. Suspended solids can be found by filtering a water sample through Whatman filter paper No.44 The maximum number of solids that can be present in water is usually regulated at 500 parts per million (ppm). pH (6.5 to 8.5) It is measure by hydrogen ion concentration in water. It is measure by Potentiometer and Colorimetric method Alkalinity & Acidity Alkalinity is caused by bicarbonates of Ca & Mg and carbonates, hydroxides of Ca, Mg, Na, K. Alkalinity effect

We are now sharing the 7 terminologies taken from the subject Surveying. The 7 terminologies are as under General Notes The purpose of surveying is to create a plan and a map. The plan is a large-scale depiction of a limited region. A map is a small-scale depiction of a limited region. The surveying principle To start with the big picture and work my way down to the details At least two measurements are required to find a new station. Geodetic surveying (area > 250 km2) is when the curvature of the earth is considered. Plane surveying (Area 250 km2) is when the curvature of the earth is not considered. On the surface of the earth, the difference between the long arch of a circle and the subtended chord is 0.1 meters for 18.2 kilometers, 0.3 meters for 54.3 kilometers, and 0.5 meters for 91 kilometers. The sum of the angles on a spherical triangle on the earth's surface and the equivalent plane triangle is 1 second per 195.5 square kilometers of land area. Rad

6 most important 1 liners from the subject Steel taken from the field Civil Engineering 1 Liners from the subject Steel Poisson's ratio "Poisson's ratio v" is a measure of the Poisson effect, which is the deformation (expansion or contraction) of material in directions perpendicular to the specific direction of loading in materials science and solid mechanics. The negative of the ratio of transverse strain to axial strain is Poisson's ratio. "v" is the amount of transversal elongation divided by the amount of axial compression for modest values of these changes. The Poisson's ratio of most materials is between 0.0 and 0.5. Poisson's ratio is around 0.5 in soft materials like rubber, where the bulk modulus is larger than the shear modulus. Poisson's ratio is approaching zero in open-cell polymer foams because the cells collapse with compression. The Poisson's ratios of several common solids are in the range of 0.2-0.3. Simeon Poisson,

Meaning of the 7 different terminologies used in the Staircase 7 different terminologies are as under TREAD A staircase tread is the physical step of a staircase where your foot is placed. RISER From one tread to the next, the vertical dimension is termed as Riser. GOING Individual goings of steps are measured from the face of the riser to the face of the riser and should be a minimum of 240mm for residential usage. STRINGERS There are two fundamental forms on the stairwell's sides. A full stringer is a board that includes treads and risers. Cut stringer is installed on the treads and risers' undersides. NOSING The front overhang of the tread, which is usually 20mm. For a cleaner appearance, modern stairs frequently do not have an overhang. LANDING Between two flights of steps, there is an intermediate level or platform. Landings, which might be a ½ landing or a ¼ landing, allow for directional adjustments in stair movement. FLOOR TO FLOOR The total rise of the
