This will help construction professionals to approach to projects for site recruitment. Is there any mapping of ongoing large construction projects in India?
Sorry it's a private question.

Dewatering can cause the advancement of hydraulic gradients that are additionally fundamental for drawing out water towards wells. Dewatering close to a site with a background marked by contamination in groundwater can bring out hydraulic gradients that can convey the dirtied groundwater towards the dewatering framework and cause contamination. By and large, polluted water requires filtration. To evade this issue, the best technique is to introduce screen dividers and vertically separate regions utilizing bentonite seals.
Dewatering can make the ground lose coherence; the result leads to ground settling. If the ground settling is vast, it can harm close by building and structures. When groundwater is removed from the soil, it makes the soil pack and squeeze. It can likewise also caused by small soil & shallow grounds being removed with the groundwater through well.
This effect can be diminished by a better plan and the utilization of good filtration and groundwater treatment that keep the particles from being separated.
Things that depend on the water like rivers, lakes, and springs have a cozy relationship with groundwater and are, in this way, influenced by dewatering and groundwater control by prohibition. It is essential to keep in mind that groundwater and water-dependent things have eco-systems and fill in as territories. An unfriendly impact of these water bodies will have a huge -ve effect on the earth.
When groundwater is removed for longer periods and in huge amounts for personal or commercial use, it can conceivably bring down groundwater levels and reduce yields. This exhaustion brings about a decrease in significant water assets for other people. An answer to this issue can be an artificial recharge method that infuses release from siphon water back in the ground.
It is crucial to perceive and decrease the effects of dewatering and groundwater control on the earth as dependable residents of the world. We should embrace great construction dewatering treatment system design, examination strategies, and better groundwater remediation innovation to alleviate these issues before it is past the point of no return.

Here, I will be discussing some useful checklist especially used for storage & cleaning of formwork.
- Using a sufficient stiff brush, the formwork should be cleaned after removal. So that dirt, dust, stubborn bits of concrete will be removed easily.
- Before storing, the uncoated & timber surface should be coated using a release agent.
- For avoiding corrosion, the steel formwork should be coated lightly with oil.
- Before storage, the damaged formwork should be repaired.
- Extra care should be taken while storing a plywood sheet & panel. They should be stored on a perfectly horizontal level platform.
- For protecting the surface, the panel should be placed face to face.
- The storage area should be well ventilated & it is protected from the rain.
Thank You.
See lessWhat is the CBR value for sub grade in road construction?
A clayey soil generally has a low CBR value (less than 8). Sands are more granular and drain better and will generally have CBR values between 15 and 35. Gravel will have the best CBR values, generally 25 and up. That is why it is suggested to save the best material to cap the subgrade.

See lessWhat is Crazing crack in Plaster?
Crazing often occur within a few hours of plaster being applied to the wall and cracks may hardly be visible until dust or moisture makes them noticeable. These cracks normally occurs when a plaster mix with a high cement content is used or the plaster is allowed to dry too quickly.

Sir,
All the collected data is very useful for the properties of soil gradation, density, bearing capacity, shrink and swell potential, lateral earth pressure and groundwater condition.
Dry density is used to determine the appropriate structural design for the pool shell.
Most critical soil property is swell potential which is highly influencing factor for structural design.
