Chapter 1 - Basic Introduction to Estimating and Quantity Surveying

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

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 most important 7 different terminologies used in the Staircase

Image
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

Few of the Important 1 Liners from the subject Irrigation Engineering Irrigation Engineering - 1 liners Kor-watering Kor-Watering of Crops refers to the first watering provided to a crop after it has grown a few centimeters. The ideal depth for kor-watering, For Rice - 19cm For Wheat - 13.5cm For Sugarcane - 16.5cm Paleo (Paleva) Paleo, also known as Paleva, is the first watering before planting the crop. Base Period The interval between the first and last waterings Crop Period Time elapsed between crop sowing and harvesting. Aqueduct (like a bridge) A canal that spans a natural drain. Super Passage Natural Drainage Across the Canal Level Crossing Both the natural drain and the canal are on the same level. Syphon Aqueduct Built where the H.F.L of natural drainage is greater than the H.F.L of the canal bed Other 1 Liners The Mass Inflow Curve is used to calculate reservoir capacity for a given demand.

Most Important 1 Liners from the Various Subjects of the Civil Engineering Common most important 1 liners from various subjects 1 Liners about Plumbing services Plumbing systems provide services such as water supply, irrigation, and sanitation, among others. Pipes Soil pipe: A soil pipe is a pipe through which human excreta flows Waste pipe: It is a pipe that carries only liquid waste. It does not carry human excreta. Vent pipe: It is a pipe that is provided for the purpose of the ventilation of the system. It facilitates the exit of foul gases. Rainwater pipe: It is a pipe that carries only rainwater. Anti-siphonage pipe: It is a pipe that is installed in the house drainage to preserve the water seal of traps. Varied sizes of pipe are commonly used in house drainage, Soil Pipe: 100mm, Waste pipe (Horizontal): 30 to 50 mm, Waste pipe (Vertical): 75 mm, Rainwater pipe: 75 mm, Vent pipe: 50 mm, Anti siphonage pipe - Connected with soil pipe: 50mm & Connecting waste pi

11 important 1 Liners from the Strength of Materials (SOM)

Image
1 liners from the Strength of Materials in Civil Engineering Important 1 liners from the strength of materials are as under, Endurance Limit The Endurance Limit is the stress threshold at which a substance has a high chance of not collapsing under reversal of stress... Or, Endurance Limit is the stress level at which a substance cracks under a significant number of stress reversals... Ductility The maximum amount of pressure that can be extracted from a material until it cracks. Malleability The ability of a material to be distorted or dispersed in a variety of ways. Compressive forces are mostly to blame when rolling, pushing, or hammering. Creep The substance undergoes more displacement with the progression of time when continuously loaded past the Elastic limit. Fatigue Degradation of a material caused by repetitive periods of stress or strain leads to gradual cracking and ultimately fracture. Tenacity The ability to withstand fracture when subjected to a tensile load. Toughness Up
