Burns & McDonnell Design Engineer Interview Questions and Answers

Various pressure tests are conducted on valves including hydrostatic test, pneumatic test, and cryogenic test.

• Hydrostatic test is conducted by filling the valve with water and pressurizing it to a specified pressure to check for leaks.

• Pneumatic test involves using air or nitrogen to pressurize the valve and check for leaks or defects.

• Cryogenic test is performed at low temperatures to ensure the valve can withstand extr...read more

A truss member is a structural component of a truss, which is a framework of beams used to support a roof or bridge.

• Truss members are typically straight and connected at joints.

• They can be made of various materials such as wood, steel, or aluminum.

• Common types of truss members include chords, webs, and diagonals.

• Truss members are designed to carry tension or compression forces efficiently.

• Examples of truss members incl

Tower load validation can be checked through structural analysis software and manual calculations.

• Use structural analysis software to simulate different load conditions on the tower.

• Calculate the expected load on the tower based on the design specifications and environmental factors.

• Compare the simulated and calculated loads to ensure they are within the safe limits.

• Perform on-site inspections and measurements to verif...read more

Patch load on towers refers to the additional weight or load that is applied to a tower structure to strengthen or modify its capacity.

• Patch load can be applied to towers to increase their capacity to withstand wind, seismic, or other loads.

• Patch load can also be used to redistribute loads on a tower to prevent structural failures.

• Examples of patch loads include adding steel plates or braces to a tower structure to inc...read more

Codes on towers refer to the specific design and construction standards that must be followed for safety and structural integrity.

• Codes on towers are regulations set by organizations like ANSI/TIA and ASCE that dictate the design, construction, and maintenance of towers.

• These codes cover aspects such as materials used, structural design, wind loading, and safety factors.

• For example, ANSI/TIA-222-G specifies the require...read more
