KEC International Procurement Engineer Interview Questions and Answers

I have worked on various DCS architectures in my career, including those for chemical plants and power plants.

• Designed and implemented DCS architecture for a chemical plant project

• Developed DCS architecture for a power plant project

• Worked on DCS architecture for a water treatment plant project

• Collaborated with team to create DCS architecture for a pharmaceutical plant project

Cutting 150 hill in 60 degree slope requires careful planning and execution.

• Conduct a thorough survey of the area to determine the best approach

• Use heavy machinery such as excavators and bulldozers to remove the hill

• Ensure safety measures are in place to prevent accidents

• Consider environmental impact and take necessary precautions

• Consult with experts in the field for advice and guidance

Protection in 150m height can be achieved through various means.

• Use of safety harness and fall protection equipment

• Installation of guardrails and safety nets

• Implementation of a comprehensive safety plan

• Regular inspection and maintenance of equipment

• Training and education of workers on safety procedures

The grade of bitumen used in hill areas depends on the temperature and altitude of the region.

• The higher the altitude, the harder the bitumen used.

• The temperature also plays a crucial role in determining the grade of bitumen.

• For example, in colder regions, a harder grade of bitumen is used to prevent cracking and deformation.

• In contrast, in warmer regions, a softer grade of bitumen is used to prevent rutting and deform

Concrete in minimum temperature requires proper mix design, curing, and protection from freezing.

• Use a mix design with low water-cement ratio and proper amount of cement and admixtures.

• Ensure proper curing by covering the concrete with blankets or insulating materials.

• Protect the concrete from freezing by using heaters or insulating blankets.

• Monitor the temperature of the concrete and the environment during and after p...read more

Cavity in tunnels can be protected by using various methods.

• Waterproofing the tunnel lining

• Using grouting techniques to fill the cavity

• Installing drainage systems to prevent water accumulation

• Regular inspections and maintenance

• Using shotcrete to reinforce the tunnel lining

• Applying rock bolts to stabilize the surrounding rock

• Using steel ribs to support the tunnel lining

Cycle time in tunnel refers to the time taken to complete one cycle of a process or operation within the tunnel.

• Cycle time can vary depending on the type of tunnel and the process being carried out.

• For example, in a transportation tunnel, cycle time may refer to the time taken for a vehicle to enter and exit the tunnel.

• In a manufacturing tunnel, cycle time may refer to the time taken to complete one production cycle.

NATM stands for New Austrian Tunneling Method, a technique used in underground construction.

• NATM is a tunneling method that involves excavating the tunnel while providing support to the surrounding rock mass.

• It was developed in Austria in the 1950s and has since been used in various tunneling projects worldwide.

• NATM involves the use of shotcrete, rock bolts, and steel ribs to support the tunnel walls and roof.

• Examples ...read more

The frequency of drilling holes in the face depends on the specific project requirements and geological conditions.

• The number of holes drilled in the face will vary depending on the project's needs and the geological conditions of the site.

• Factors such as the type of rock, the size of the excavation, and the equipment being used will all influence the frequency of drilling.

• It is important to carefully plan and execute ...read more

Proholes is not a known term in engineering. No data available.

Drain holes are necessary to prevent water accumulation and damage to structures or equipment.

• Drain holes allow water to escape from areas where it can cause damage or corrosion.

• They are commonly used in outdoor furniture, boats, and buildings to prevent water accumulation.

• Drain holes can also be used in machinery to prevent damage from water or other liquids.

• Proper placement and size of drain holes is important to ens

The amount of accelerator used in shotcrete depends on various factors.

• The type of accelerator used affects the amount required.

• The desired strength and setting time also play a role.

• The ambient temperature and humidity can affect the amount needed.

• Typically, 1-5% of the cement weight is used as accelerator.

• The manufacturer's recommendations should be followed for best results.
