Accepted Answer

Coping is a protective layer on top of a wall, lap length and joggle are reinforcement techniques, working drawings show construction details, 250, 450, and 500 reinforcement bars differ in diameter, initial setting time is the time it takes for cement to harden, DPC and PPC are measurement units, sand filling is used for compacting soil, and shuttering is a temporary formwork.

Coping is a protective layer placed on top of a wall to prevent water penetration and provide a finished appearance.
Lap length is the overlap of reinforcement bars to ensure continuity and strength in concrete structures.
Joggle is a technique used to create a mechanical connection between two concrete elements.
Working drawings are detailed plans that show the dimensions, materials, and construction methods for a project.
Submission drawings are the final drawings submitted for approval before construction begins.
250, 450, and 500 reinforcement bars refer to the diameter of the bars, with 500 being the largest.
Initial setting time is the time it takes for cement to harden and gain strength after mixing with water.
DPC stands for Damp Proof Course, which is a layer of waterproof material used to prevent moisture from rising in a building.
PPC stands for Portland Pozzolana Cement, which is a type of cement that contains pozzolanic materials for improved durability.
