Navayuga Engineering Company Bridge Design Engineer Interview Questions and Answers

Cube mould size is a standard size used for testing the compressive strength of concrete.

• Cube moulds are typically made of steel or cast iron.

• The standard size for cube moulds is 150mm x 150mm x 150mm.

• Other sizes such as 100mm x 100mm x 100mm and 200mm x 200mm x 200mm are also used.

• The moulds are filled with concrete and left to cure before being tested for compressive strength.

• Cube moulds are used to ensure that the c...read more

To calculate the weight of an 8mm diameter steel rod, use the formula: weight = volume x density.

• Calculate the volume of the rod using the formula: volume = π x (diameter/2)^2 x length

• Find the density of steel, which is typically around 7850 kg/m^3

• Multiply the volume by the density to get the weight of the rod

Leveling is the process of determining the height or elevation of a point or surface relative to a reference point.

• Leveling is commonly used in civil engineering and construction to ensure accurate measurements and proper alignment.

• It involves the use of leveling instruments such as a level, theodolite, or laser level.

• The process typically includes setting up benchmarks or reference points, taking readings at different...read more

The diameter of six mm refers to the size or measurement of a circular object that is six millimeters in width.

• The diameter is the distance across the center of a circle, passing through the circumference.

• A six mm diameter can be visualized as a circle with a width of six millimeters.

• It is a common measurement used in various industries, including engineering and manufacturing.

• For example, a six mm diameter steel rod w...read more

LEP stands for Load Equivalent Factor for Pavement design.

• LEP is used in pavement design to determine the load-carrying capacity of the pavement.

• The formula for LEP depends on the specific design method being used.

• For example, in the AASHTO design method, LEP is calculated using the formula: LEP = (ESAL/1000) * (1 + 0.003 * (T - 3))

• Here, ESAL is the Equivalent Single Axle Load and T is the pavement design period in yea...read more

Pre Cast work is the process of manufacturing concrete elements in a factory and transporting them to the construction site for assembly.

• Pre Cast work involves creating concrete elements such as walls, columns, and beams in a factory setting

• These elements are then transported to the construction site for assembly

• Pre Cast work can save time and money on construction projects

• Examples of Pre Cast elements include precast ...read more

Pipe laying, sewer networking, and road restoration are essential tasks for civil site engineers.

• Pipe laying involves the installation of pipes for water supply, drainage, and sewage systems.

• Sewer networking involves connecting pipes to create a network for the transportation of sewage and wastewater.

• Road restoration involves repairing and maintaining roads and pavements that have been damaged due to construction work.

• ...read more

IC chamber is used for the treatment of industrial effluent and wastewater.

• IC stands for Ion Exchange Chromatography

• IC chamber is used to remove heavy metals, organic compounds, and other pollutants from wastewater

• It works by exchanging ions in the wastewater with ions in the resin beads inside the chamber

• Effluent treated in IC chamber can be reused for industrial purposes or discharged into the environment

• IC chamber i...read more
