What safeguards do you use to avoid mistakes in drawing a plan?
What are the problems associated with prestressed concrete piles?
Since the installation method of Daido piles is changed, construction problems like deformation of pile tip shoes, crushing of concrete at pile tip etc. occur.

What is the difference between the modulus of rupture and flexural strength?
Flexural strength is the maximum strength (stress) either yield or up to fracture that a structure or element or a member could bear. It could be measures in terms of modulus of rupture at yield also. Where in modulus of rupture is just showing the present stress condition within the member or elemeRead more
Flexural strength is the maximum strength (stress) either yield or up to fracture that a structure or element or a member could bear. It could be measures in terms of modulus of rupture at yield also.
Where in modulus of rupture is just showing the present stress condition within the member or element itself. If the member is on the verge of failure i.e on the verge of fracture than the modulus of rupture will give Flexural strength.

Pozzolanic reaction is the reaction which continue to occur as long as calcium hydroxide is present, there is sufficient water for the reaction to occur, and there is available space for the reaction products to reside.

Cadastral survey is a comprehensive study of land, its location, its value, etc. A cadastral survey shows the extent, boundaries, value, and ownership of land. Through these surveys, authorities assign a numerical identity to land.

Advantages of remote sensing :-
1. Large area coverage: Remote sensing allows coverage of very large areas which enables regional surveys on a variety of themes and identification of extremely large features.
2. Remote sensing allows repetitive coverage which comes in handy when collecting data on dynamic themes such as water, agricultural fields and so on.
3. Remote sensing allows for easy collection of data over a variety of scales and resolutions.
4. A single image captured through remote sensing can be analyzed and interpreted for use in various applications and purposes. There is no limitation on the extent of information that can be gathered from a single remotely sensed image.
5. Remotely sensed data can easily be processed and analyzed fast using a computer and the data utilized for various purposes.
6. Remote sensing is unobstructive especially if the sensor is passively recording the electromagnetic energy reflected from or emitted by the phenomena of interest. This means that passive remote sensing does not disturb the object or the area of interest.
7. Data collected through remote sensing is analyzed at the laboratory which minimizes the work that needs to be done on the field.
8. Remote sensing allows for map revision at a small to medium scale which makes it a bit cheaper and faster.
9. Color composite can be obtained or produced from three separate band images which ensure the details of the area are far much more defined than when only a single band image or aerial photograph is being reproduced.
10. It is easier to locate floods or forest fire that has spread over a large region which makes it easier to plan a rescue mission easily and fast.
11. Remote sensing is a relatively cheap and constructive method reconstructing a base map in the absence of detailed land survey methods.
Disadvantages of remote sensing :-
1. Remote sensing is a fairly expensive method of analysis especially when measuring or analyzing smaller areas.
2. Remote sensing requires a special kind of training to analyze the images. It is therefore expensive in the long run to use remote sensing technology since extra training must be accorded to the users of the technology.
3. It is expensive to analyze repetitive photographs if there is need to analyze different aspects of the photography features.
4. It is humans who select what sensor needs to be used to collect the data, specify the resolution of the data and calibration of the sensor, select the platform that will carry the sensor and determine when the data will be collected. Because of this, it is easier to introduce human error in this kind of analysis.
5. Powerful active remote sensing systems such as radars that emit their own electromagnetic radiation can be intrusive and affect the phenomenon being investigated.
6. The instruments used in remote sensing may sometimes be un-calibrated which may lead to un-calibrated remote sensing data.
7. Sometimes different phenomena being analyzed may look the same during measurement which may lead to classification error.
8. The image being analyzed may sometimes be interfered by other phenomena that are not being measured and this should also be accounted for during analysis.
9. Remote sensing technology is sometimes oversold to the point where it feels like it is a panacea that will provide all the solution and information for conducting physical, biological or scientific research.
10. The information provided by remote sensing data may not be complete and may be temporary.
11. Sometimes large scale engineering maps cannot be prepared from satellite data which makes remote sensing data collection incomplete.

Hi Nikeeta,
Nice to read your answer to your question.
I would like to add some significant mistakes that freshers civil engineers/architectures make while drawing plan
- The plan is not co-ordinated – In many construction companies, due to lack of coordination between architectural drawing with electrical and electric drawing with mechanical for electric wires. Conduits, etc., which leads to a massive problem in the forward lane.
- Incomplete Plan: If an inexperienced engineer is going to draft complex building structures, many issues arise. Complete construction plans consist of multiple sheets, including architectural, mechanical engineering, electrical engineering, civil engineering, structural engineering, and possibly other disciplines. The more complex the project, the more sheets of drawings there will be. When the plans are not complete, it increases the risk for the lender.
- Detail lacking: To reduce time, some architects/engineers will skip some of the drawings’ details. Rather than drawing the details of a roof edge dimensions or a window detail, they’ll add vague notes about what that portion of the construction will contain. That leads to significant problems for site engineers and results in error in structure. Once the contractor is on-site, and they have to attempt to interpret the puzzling notes into actual construction, they will generally have questions about exactly how that is to be done.
- The wrong set of PCR values: The planning process produces various progress sets of drawings, from the original conceptual design drawings to progress collections of construction drawings. Ultimately, the “for construction” set that the contractor will use to build the building.
