A theodolite is set up at station A and a 3 m long staff is held vertically at station B. The depression angle reading at 2,5 m marking on the staff is 6°10′. The horizontal distance between A and B is 2200 m. Height of instrument at station A is 1.1 m and R.L, of A is 880.88 m. Apply the curvature and refraction correction, and determine the R.L. of B (in m).

Fire Place Construction and Layout

A fireplace is a chamber, made of different materials usually constructed to contain the fire for various applications. A fireplace is often known as a hearth. Fireplaces can be made of bricks, steel, stone, and concrete. Fireplaces serve as room heaters for cold areas and vary in design and heat efficiency.
