Site Plan Requirements

A site plan (also known as a plot plan) is a diagram or process to show the proposed improvements on an existing property. A site plan is important, as it provides information regarding the landscape features of a given plot of land. Zoning is done or can be understood with the help of a site plan.

Question

An instrument was set up over TBM 1, and backsights onto point A before sighting
onto B. The instrument was then moved to B, back-sighted onto TBM 1 and then
sighted at C. It was moved once again, to C, back-sighted onto B before being
sighted onto D. The line between TBM 1 to point A is to act as the reference plane
for the site (taken as zero degrees: 0° 0' 0"). Note that the instrument would not
provide the ability to zero the horizontal angles before taking a reading.

1 - A, B and C are three triangulation stations whose positions were determined by the angle measured at station B to A and C, respectively. The distance BC was measured to be 1200 m long and CD is 965 m long. The azimuth of C from B is 140° and that of A from B is 286°30’. A sounding at F (south of three stations) was taken from a boat and the angle BFA and BFC were measured simutaneously by two sextants from the boat to the three stations ABC as 22°30’ and 28°15’, respectively. How far is F from B?
