Laying blocks involves precise techniques for alignment, mortar application, and ensuring structural integrity.

• Prepare the foundation: Ensure the base is level and clean before starting.

• Mix mortar: Use the right ratio of cement, sand, and water for optimal adhesion.

• Lay the first block: Start at a corner, applying mortar to the bottom and sides.

• Check alignment: Use a level to ensure blocks are straight and even.

• Stagger ...read more

BMD for sway frame is a diagram showing the variation of bending moment along the length of the frame.

• BMD for sway frame will have a shape similar to a zigzag pattern due to the presence of sway in the frame.

• The bending moment will be maximum at the points where the frame experiences maximum sway.

• The BMD can be drawn by analyzing the internal forces and moments acting on the frame.

Drawing piperack elevations involves creating detailed drawings of the structure from different viewpoints.

• Start by determining the dimensions and layout of the piperack

• Use software like AutoCAD to create accurate and detailed drawings

• Include all necessary details such as pipe sizes, supports, and connections

• Label all components clearly for easy understanding

• Review and revise the drawings as needed for accuracy

EHS stands for Environment, Health, and Safety. It refers to the laws, rules, standards, and programs that are designed to protect the health and safety of employees and the public as well as the environment.

• EHS involves identifying and assessing risks in the workplace related to health, safety, and the environment.

• It includes implementing measures to control and mitigate these risks, such as providing proper training,...read more
