Ramboll Design Engineer/Manager Interview Questions and Answers

Design of pier involves considering various factors such as load capacity, soil conditions, water level, and environmental impact.

• Determine the load capacity and type of pier required

• Analyze soil conditions and water level to determine foundation type

• Consider environmental impact and regulations

• Design for durability and maintenance

• Ensure safety measures are in place

Rigid pile caps are designed to transfer the load from the superstructure to the piles. The design should consider the pile arrangement, load distribution, and soil properties.

• The pile cap should be designed to distribute the load evenly to the piles.

• The pile arrangement should be considered to ensure that the pile cap is not overloaded.

• The soil properties should be analyzed to determine the bearing capacity of the pil...read more

Prestressing losses occur during the transfer of prestress from the jacks to the concrete. These losses can be divided into two stages.

• The first stage is immediate losses, which occur due to friction between the strands and the ducts, anchorage slip, and elastic shortening of the concrete.

• The second stage is time-dependent losses, which occur due to creep and shrinkage of the concrete, relaxation of the steel, and temp...read more

Design of steel members and connections involves determining the appropriate size and shape of steel components and how they are connected.

• Consider the loads and stresses that the steel members will be subjected to

• Select appropriate steel sections based on their strength and stiffness

• Design connections that can transfer loads between members without failure

• Ensure that the design complies with relevant codes and standar...read more

Pre-tension is applied before concrete is poured, while post-tension is applied after concrete has hardened.

• Pre-tension involves stretching steel cables or bars before pouring concrete to create tension in the concrete as it sets.

• Post-tension involves inserting steel cables or bars into hardened concrete and then tensioning them to create compression in the concrete.

• Pre-tension is typically used in precast concrete ele...read more

Analysis and design of piles involves determining the load capacity and selecting the appropriate type of pile for a given soil condition.

• Pile load capacity is determined through various methods such as static load tests, dynamic load tests, and pile integrity tests.

• Factors such as soil type, groundwater level, and seismic activity must be considered when selecting the type of pile.

• Common types of piles include driven ...read more

Bracing should be added in the weak axis direction to provide stability and prevent buckling.

• Bracing should be added in the weak axis direction to prevent buckling.

• Bracing helps to stabilize the structure and distribute loads more efficiently.

• Examples of bracing in steel structures include diagonal bracing, cross bracing, and portal bracing.

Different checks in footing include bearing capacity check, settlement check, sliding check, and overturning check.

• Bearing capacity check ensures the soil can support the load without failure.

• Settlement check ensures the footing settles within acceptable limits.

• Sliding check ensures the footing does not slide on the soil.

• Overturning check ensures the footing does not overturn due to lateral forces.

One way shear occurs in footings when load is applied in one direction, while two way shear occurs when load is applied in two directions.

• One way shear typically occurs in rectangular footings where the load is applied in one direction.

• Two way shear occurs in square footings or when the load is applied in two directions.

• One way shear is calculated using the formula Vc = 0.5 * f'c * b * d, while two way shear is calcula

I have worked on various types of structures including commercial buildings, residential homes, bridges, and industrial facilities.

• Commercial buildings

• Residential homes

• Bridges

• Industrial facilities

LOD stages in BIM refer to the Level of Development which defines the amount of detail and accuracy of a model at different stages of a project.

• LOD 100: Conceptual design with basic massing and spatial relationships

• LOD 200: Generalized elements with approximate quantities, size, shape, location, and orientation

• LOD 300: Specific elements with accurate quantities, size, shape, location, and orientation

• LOD 400: Detailed e...read more

The boom length of a tower crane varies depending on the model and manufacturer.

• Tower crane boom length can range from 30 meters to over 100 meters.

• The boom length determines the maximum height and reach of the crane.

• Factors such as weight capacity and wind speed also affect the boom length.

• Some popular tower crane models and their boom lengths include: Potain MDT 98 (55 meters), Liebherr 630 EC-H 40 (40 meters), and T
