Sterling & Wilson Senior Civil Site 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

The process of tower foundation involves several steps that are carried out day by day.

• Day 1: Site preparation and layout survey

• Day 2: Excavation for foundation

• Day 3: Reinforcement placement

• Day 4: Formwork installation

• Day 5: Concrete pouring

• Day 6: Curing of concrete

• Day 7: Removal of formwork

• Day 8: Quality inspection and testing

• Day 9: Backfilling around the foundation

• Day 10: Final inspection and documentation

Cube mould size refers to the dimensions of the mould used to cast concrete cubes for testing.

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

• The most common cube mould size used in construction is 150mm x 150mm x 150mm.

• Other sizes like 100mm x 100mm x 100mm or 200mm x 200mm x 200mm may also be used depending on the requirements.

• Cube moulds have removable base plates to facilitate easy removal of the hardened conc...read more

Quality points at the pouring time of concrete include proper mix proportions, correct placement, adequate compaction, and appropriate curing.

• Proper mix proportions ensure the desired strength and durability of the concrete.

• Correct placement involves placing the concrete in the designated location without segregation or excessive bleeding.

• Adequate compaction ensures that there are no voids or air pockets in the concret...read more

Sloped cutting refers to the excavation of soil or rock at an inclined angle to create a slope or incline.

• Sloped cutting is commonly used in construction projects to create roadways, railways, or canals on hilly terrains.

• It involves removing the excess material from a higher elevation to a lower elevation, forming a sloping surface.

• The angle of the slope is determined based on factors such as soil stability, desired gr...read more

The size of bricks varies depending on the country and region they are used in.

• In the United States, the standard size for bricks is 2 1/4 x 3 3/4 x 8 inches.

• In the United Kingdom, the standard size for bricks is 65mm x 102.5mm x 215mm.

• Bricks can also come in different shapes and sizes for specific purposes, such as bullnose bricks for rounded edges.

• The size of bricks can affect the strength and stability of a structur...read more
