10+ Instellars Global Consulting Interview Questions and Answers

A metric chain is 20 meters long and consists of 100 links, so each link is 0.2 meters long.

• A metric chain is a measuring tool used in land surveying.

• It is 20 meters long and consists of 100 links.

• Each link is therefore 0.2 meters long.

• Metric chains are used to measure distances on land with high accuracy.

Concrete grades are classifications of concrete based on its strength and durability.

• Concrete grades range from M5 to M100, with M representing mix and the number representing the compressive strength in megapascals (MPa)

• The ratio of concrete mix varies depending on the grade, with higher grades requiring more cement, sand, and aggregate

• For example, M20 concrete has a mix ratio of 1:1.5:3, meaning 1 part cement, 1.5 parts sand, and 3 parts aggregate

Auto level parts are components of an auto level instrument used in surveying and construction.

• Auto level parts include the telescope, leveling screws, bubble level, focusing knob, and tripod.

• The telescope is used to sight and measure vertical and horizontal angles.

• Leveling screws are used to adjust the instrument's level.

• The bubble level helps in ensuring the instrument is properly leveled.

• The focusing knob is used to adjust the focus of the telescope.

• A tripod is used to sup...read more

A right angle is a 90-degree angle formed by two perpendicular lines.

• A right angle can be found using a protractor or a T-square.

• A right angle can also be identified by the intersection of two perpendicular lines.

• In construction, a plumb bob or level can be used to ensure that a corner is at a right angle.

Camber is the curvature of a road or track, while gradient refers to the slope or incline of the road.

• Camber is the transverse slope of a road, which helps with drainage and stability.

• Positive camber means the road is higher in the middle and slopes down towards the edges.

• Negative camber means the road is lower in the middle and slopes up towards the edges.

• Gradient refers to the longitudinal slope of a road, indicating the rise or fall over a given distance.

• A positive gradien...read more

• Designed and constructed foundations for residential and commercial buildings

• Used excavators, bulldozers, and concrete mixers for construction

• Ensured proper curing and finishing of concrete works

• Implemented quality control measures to ensure durability and strength of foundations

• Collaborated with architects and engineers to ensure compliance with building codes and regulatio...read more

Contours are imaginary lines joining points of equal elevation on the ground surface.

• Contours are used to represent the shape and elevation of the land on a map.

• They help in determining the slope, height, and depth of the land.

• Contour lines are drawn at a constant vertical interval, known as the contour interval.

• The contour interval is chosen based on the scale of the map and the terrain being surveyed.

• Contour lines that are close together indicate steep slopes, while those t...read more

Different types of beds in pavement include granular, stabilized, and asphalt-treated.

• Granular beds are made of crushed stone or gravel and provide good drainage.

• Stabilized beds use a binding agent like cement or lime to improve strength and durability.

• Asphalt-treated beds have a layer of asphalt on top of a granular base for added strength and water resistance.

Indirect expenses are costs that cannot be directly attributed to a specific product or service.

• Indirect expenses are also known as overhead costs.

• Examples of indirect expenses include rent, utilities, and office supplies.

• These expenses are necessary for the operation of a business but are not directly tied to the production of goods or services.

• Indirect expenses are typically allocated to products or services based on a predetermined formula or percentage.

• Understanding indir...read more

M30 =M means 30Means

• M30 refers to a specific grade of concrete

• The 'M' stands for mix design

• The number following 'M' represents the compressive strength of the concrete in megapascals (MPa)

• For example, M30 means the concrete has a compressive strength of 30 MPa

Specific gravity of Bitumen is the ratio of its density to the density of water at a specified temperature.

• Specific gravity of Bitumen is an important property that determines its suitability for various applications.

• It is measured using a pycnometer or a hydrometer.

• The specific gravity of Bitumen ranges from 0.97 to 1.02.

• Higher specific gravity indicates higher density and hardness of Bitumen.

• Specific gravity also affects the viscosity and adhesion properties of Bitumen.

Bending moment and shear force are key concepts in structural engineering, used to analyze the effects of loads on beams and other structures.

• Bending moment is the internal moment that causes a beam to bend. It is calculated as the product of the force applied and the distance from the point of application.

• Shear force is the internal force that causes one part of a material to slide past another part. It is calculated as the sum of all forces acting perpendicular to the axis ...read more

PQC thickness refers to the thickness of the pavement quality concrete layer in highway construction.

• PQC thickness is an important factor in determining the durability and performance of the highway pavement.

• It is typically measured in millimeters or inches.

• The thickness of PQC depends on various factors such as traffic load, subgrade strength, and climate conditions.

• For example, in heavy traffic areas, a thicker PQC layer may be required to withstand the load.

• PQC thickness i...read more
