Explanation

Plot area = 10×5=50m^2

Tile size = $50cm\times 50cm=0.5m\times 0.5m$

Tile area = 0.5×0.5=0.25m^2

Number of tiles = $50÷0.25$

=200​

Explanation

• A drop panel is a thickened section of a flat concrete slab around a column that helps support extra weight and heavy loads

Additional information:

• Waist slab: The main structural part of a stair.
• Rib: A narrow beam that supports a ribbed or joist floor.
• Lintel: A beam placed above a door or window opening.

Explanation

• A bridge abutment primarily experiences earth pressure at-rest.
• Rigid Structure: Bridge abutments are massive and tightly restrained.
• No Movement: The structure cannot tilt or slide away from the backfill.
• At-Rest Condition: Zero lateral displacement results in earth pressure at rest (K_0).

Explanation

• The Slump Test is used to measure the consistency/workability of fresh concrete.
• It indicates how easily concrete can be mixed, placed, and compacted.

Explanation

• Loads are first carried by the slab.
• The slab transfers the load to the beams.
• Beams transfer the load to the columns.
• Columns transfer the load to the foundation.
• The foundation finally transfers the load safely to the soil.

Explanation

• The Slump Test is commonly used to determine the consistency/workability of fresh concrete.
• It measures the decrease in height (slump) of concrete after the slump cone is removed.

Explanation

• 3 equations of condition are added by an internal hinge in a 3D frame when 2 members meet.
• Formula: The exact number of releases is 3(m' - 1), where m' is the number of connected members.
• Action: It removes 3 rotational connections (bending and twisting moments) but still passes 3 translational forces (pushing, pulling, and sliding forces)
• Result: It reduces the total structural locking count (static indeterminacy) by 3.

Explanation

• The Sand Replacement Method is a field test used to determine the in-situ (field) density of soil.
• It is commonly used for compacted soil and earthwork.
• The method involves excavating a small hole in the soil.
• The volume of the hole is determined using calibrated sand

Explanation

• Plastic formwork: Highly flexible and smooth, making it the best choice for casting complex, intricate ornamental designs.

Additional information:

• Steel formwork: Rigid, heavy, and best for large, flat, repetitive concrete structures.
• Timber formwork: Used for basic, traditional shapes but difficult to carve into fine decorative details.
• Plywood formwork: Creates smooth, flat surfaces but cannot easily form intricate 3D architectural patterns.

Explanation

Joint venture: Two or more companies form a temporary partnership to pool resources and complete a specific job together.

Additional information

• Subcontracting: One main contractor hires another independent company to do a small part of their project
• Tendering: The process where companies submit competitive price offers (bids) to win a construction contract.
• Negotiation: Direct business discussions between an owner and a contractor to agree on project costs and terms without open bidding.
