10+ Stellapps Technologies Interview Questions and Answers

The cement concrete ratio refers to the proportion of cement to aggregates in a concrete mixture.

• The ratio is typically expressed as a combination of cement, sand, and coarse aggregates.

• For example, a common ratio for general construction is 1:2:4, which means one part cement, two parts sand, and four parts coarse aggregates.

• The ratio may vary depending on the desired strength, workability, and durability of the concrete.

• Different types of concrete, such as high-strength or l...read more

A simply supported beam is a structural element that is supported at both ends and is free to rotate and deflect under load.

• A simply supported beam is one of the most common types of structural elements used in construction.

• It consists of a beam that is supported at two points, typically with pins or rollers.

• The beam is free to rotate and deflect under load, allowing it to distribute the applied forces.

• Simply supported beams are commonly used in bridges, buildings, and other ...read more

Compressive strength is the maximum amount of compressive stress a material can withstand before it fails.

• Compressive strength measures a material's ability to resist compression forces.

• It is an important property in civil engineering, as it determines the load-bearing capacity of structures.

• Compressive strength is typically measured in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa).

• For example, the compressive strength of concrete is ...read more

Estimation is the process of calculating the approximate cost, time, and resources required for a construction project.

• Estimation involves analyzing the project requirements and specifications.

• It includes determining the quantities of materials, labor, and equipment needed.

• Estimation also considers factors like project duration, site conditions, and potential risks.

• Various methods like quantity takeoff, cost databases, and historical data are used for estimation.

• Estimation he...read more

Columns are vertical structural elements that support the weight of a building or structure.

• Columns are typically made of materials such as concrete, steel, or wood.

• They are designed to transfer the load from the upper parts of the structure to the foundation.

• Columns come in various shapes and sizes, including rectangular, circular, and square.

• They are often used in combination with beams and slabs to form the framework of a building.

• Examples of columns can be seen in the pil...read more

The foundation is the lowermost part of a structure that transfers the load of the structure to the underlying soil or rock.

• It provides stability and prevents settlement of the structure.

• Foundations can be shallow or deep, depending on the soil conditions and the size of the structure.

• Common types of foundations include spread footings, pile foundations, and mat foundations.

• For example, a building with a spread footing foundation will have concrete footings that distribute th...read more

The full form of Civil Engineer is a professional who designs, constructs, and maintains infrastructure projects.

• Civil Engineer stands for a professional who specializes in the planning, design, construction, and maintenance of infrastructure projects.

• They are responsible for ensuring the safety, functionality, and sustainability of structures such as buildings, bridges, roads, dams, and more.

• Civil Engineers work on various aspects including surveying, geotechnical engineerin...read more

BBS stands for Bar Bending Schedule, which is a detailed list of reinforcement bars required for a construction project.

• BBS is used to provide information about the type, size, quantity, and placement of reinforcement bars in a structure.

• It helps in estimating the amount of steel required and ensures proper reinforcement detailing.

• BBS includes information about the cutting length, shape, and bending details of each bar.

• It is prepared based on the structural drawings and speci...read more

Survey is the process of measuring and mapping the physical features of a land area.

• Survey is used to determine the boundaries, contours, and elevations of a piece of land.

• It involves the use of various instruments and techniques to collect data about the land.

• Survey data is used in the design and construction of infrastructure projects.

• Examples of surveys include topographic surveys, boundary surveys, and construction surveys.
