Ramboll Senior CAD Technician Interview Questions, Process, and Tips

To draw a rough sketch of RCC deck slab and level it, start by identifying the dimensions and then sketching the slab with proper levels.

• Identify the dimensions of the RCC deck slab

• Sketch the slab with proper levels

• Ensure that the sketch is rough and not to scale

• Label the important features of the slab such as beams and columns

The lap provided in RCC column depends on the diameter of the column and the load it is expected to bear.

• The lap length is usually 50 times the diameter of the column.

• For example, if the diameter of the column is 300mm, the lap length would be 15000mm or 15m.

• The lap length also depends on the load the column is expected to bear.

• For heavy loads, the lap length should be increased.

• The lap length should be calculated by a...read more

A bridge cross section with required reinforcement.

• Draw a cross section of a bridge with dimensions and materials used.

• Identify the areas that require reinforcement based on the load and stress analysis.

• Show the reinforcement required using appropriate symbols and annotations.

• Include details such as bar diameter, spacing, and cover.

• Consider the type of reinforcement needed, such as steel or fiber-reinforced polymer.

• Ens...read more

Couplers are provided in reinforcement to join two reinforcement bars together.

• Couplers are used to join reinforcement bars when the length of the reinforcement is not sufficient.

• Couplers are used to avoid the lap length of reinforcement bars.

• Couplers are used to reduce the congestion of reinforcement bars in the structure.

• Couplers are used to provide better structural integrity and strength.

• Couplers are commonly used ...read more
