The diameter of binding wire used in construction varies depending on the type of construction work.

• The diameter of binding wire used in construction ranges from 0.9 mm to 1.6 mm.

• Thicker binding wire is used for heavy-duty construction work.

• Thinner binding wire is used for lighter construction work.

• The most commonly used binding wire diameter in construction is 1.2 mm.

• The diameter of binding wire is important as it aff...read more

The aim of construction in site is to create a safe, functional and aesthetically pleasing structure.

• Ensure safety of workers and public

• Meet functional requirements of the structure

• Create an aesthetically pleasing design

• Use appropriate materials and techniques

• Adhere to building codes and regulations

The minimum grade of RCC is M20.

• RCC stands for Reinforced Cement Concrete.

• The grade of RCC is determined by the compressive strength of concrete.

• M20 grade means the compressive strength of concrete is 20 N/mm².

• Higher grades of RCC are used for structures that require higher strength, such as bridges and high-rise buildings.

PSC is pre-stressed concrete while RCC is reinforced concrete.

• PSC has pre-stressed steel while RCC has reinforcing steel.

• PSC is stronger and more durable than RCC.

• PSC is used in bridges, high-rise buildings, and other structures that require high strength and durability.

• RCC is used in residential and commercial buildings, bridges, and other structures that require moderate strength and durability.

Minimum steel diameter depends on various factors such as load, span, and type of structure.

• Minimum steel diameter is determined by the design engineer based on the load and span of the structure.

• The type of structure also plays a role in determining the minimum steel diameter.

• For example, a bridge would require a larger diameter steel than a residential building.

• The minimum steel diameter is also influenced by the typ...read more

Several tools are required for pile installation on site.

• The number of tools required for pile installation depends on the type of pile being installed.

• Some common tools required for pile installation include pile hammers, augers, drilling rigs, cranes, and vibratory hammers.

• The number of tools required also depends on the size and depth of the pile being installed.

• Other factors such as soil conditions and accessibilit...read more
