How do you estimate individual wall method?
To get the length of longwall or shortwall, calculate first the centre line lengths of individual walls. Then the length of long wall, (out to out) may be calculated after adding half breadth at each end to its centre line length.
How do you calculate building estimate?
Before you directly start calculating quantity, you must precisely and correctly read the construction drawing.
- Check dimension of each block is provided or not.
- The check Schedule of the opening is there.
- Check specification of work.
- Check the thickness of the wall is same or changes.
For which kind of building the Centre line method is specially adopted for estimating?
3. The ‘centre line method’ is specially adopted for estimating? Explanation: By center-line method, estimate for earthwork, concrete work or brick work for all walls of the building can be done at a time. If there are junctions, it needs to be carefully calculated deducting the widths.
Which estimation methods is more reliable Centre line or wall methods?
Long wall and short wall method saves huge sum of money on big projects that as accurate results are obtained with it compared to centre line method. Centre line method finishes work faster as compared to long wall and short wall method as approximate calculations are involved here.
What are the method of estimates?
There are 12 Types of Estimates in civil engineering as Approximate or Rough Estimate, Plinth Area Estimate, Service Unit Method, Floor Area Method, Carpet Area Method, Typical Bay Method, Cost Comparison Method.
What are the methods of estimation?
Here are six common estimating methods in project management:
- Top-down estimate.
- Bottom-up estimate.
- Expert judgment.
- Comparative or analogous estimation.
- Parametric model estimating.
- Three-point estimating.
How do you do a civil estimate?
The total cost per unit quantity of each item is analyzed and worked out. Then the total cost for the item is found by multiplying the cost per unit quantity by the number of units. For example, while estimating the cost of a building work, the quantity of brickwork in the building would be measured in cubic meters.
How do you find the centerline value?
Divide the total of the subgroup by the total defects to derive the centerline of the p-chart. In this example: 2,709/3,124 = 0.87.
Is specially adopted for estimating?
The ‘centre line method’ is specially adopted for estimating.
Which is the most reliable estimate?
Detailed Estimation
Answer: The Detailed Estimation is the most reliable estimation.
How do you calculate the length of a center line?
Total center line length = 2 x (5.3+5.3) + 3 x 4.3 = 34.1 m. Quantity of plinth beam = Total Centre line length x Breadth of the beam x Depth of beam. Quantity of wall plaster for 2 sides = Total center line length x Height of wall x Thickness of plaster.
How to prepare centre to centre line estimate?
Centre to centre line method is one of the methods for preparing an estimate. In this method first, calculate the centre line length of the wall, and then multiply it with the breadth and depth of the wall to find out quantity.
How to estimate the total center line length of a building?
In this method of estimation, the total center line length of walls in a building is first calculated, then the center line length is multiplied with the breadth and depth of respective item to get the total quantity at a time. Fir different sections of walls in a building, the center-line length for each type shall be worked out separately.
What is center line method of estimation?
What Is Center Line Method: In this method of estimation, the total center line length of walls in a building is first calculated, then the center line length is multiplied with the breadth and depth of respective item to get the total quantity at a time.
What are the different cost estimation methods for building construction?
There are different cost estimation methods for calculating the quantity of various item like earthwork, foundation, concrete & brickwork (plinth and superstructure). But mainly below two methods are used: Here we discuss centre to centre line method. Centre to centre line method is one of the methods for preparing an estimate.
