L&T Construction QA/QC Manager Interview Questions and Answers

Underground Metro segment casting yard steam curing is a process used to accelerate the strength gain of concrete segments for tunnel construction.

• Steam curing involves applying high temperature steam to the concrete segments to speed up the hydration process.

• This method helps in achieving the required strength of the segments in a shorter time period.

• Steam curing is often used in precast concrete production for underg...read more

Segment casting cycle is the process of creating segments for construction projects using precast concrete.

• Segments are cast in a controlled environment to ensure quality and consistency.

• The casting cycle includes preparing molds, pouring concrete, curing, demolding, and finishing.

• Segments are then transported to the construction site and assembled to form the final structure.

Segments repairing process involves identifying and fixing issues in different sections of a product or system.

• Identify the specific segment that needs repair

• Analyze the root cause of the issue

• Develop a plan for repairing the segment

• Implement the repair process

• Test the repaired segment to ensure functionality

Monitoring performance involves setting clear expectations, providing feedback, tracking progress, and addressing any issues that arise.

• Set clear performance expectations for team members

• Provide regular feedback on performance

• Track progress towards goals and objectives

• Address any performance issues promptly and constructively

Bentonite is used as a drilling fluid to stabilize boreholes before pulsing.

• Bentonite is mixed with water to form a slurry and pumped into the borehole.

• The slurry fills the borehole and stabilizes the walls, preventing collapse.

• After the bentonite has set, pulsing can be done without the risk of borehole collapse.

• Pulsing is a technique used in geophysical exploration to measure the properties of the subsurface.

The safety person's roles and responsibilities as per the BOCW act include ensuring safety measures are in place, conducting safety inspections, and providing safety training.
