Explain why architects prefers to use metric in comparison to imperial unit of measurement.more accurate.
Explain what are the common scales and drawing features represented in a Topography or Lanscape map?
1:1250 - 1: 2500
What is the dimension sketch in comparison to field sketch
dimensioned sketch takes the field sketch one tep further. the aim is to annotete your sketch plaln with accurate meaurements to show wall lengths and thickenss. it should include all the necessary dimentsions for someone who has not seen the building to understand it and if required, construct a scle drawing. sketches should be neat, in proportion and large enought to allow the ..
Explain how scale helps to record the measuremetns and facts of measured oject accurately.
its imposible to draw 1:1
purpose of scal is to be ableto accurately represent spaces, objects or even graphics to a smller, more pratica ...
Elaborate in your own understanding why it is not a good practice to label dimensions on drawing in such manner as shown below.
Dimesioning symebols that crosses each othr confuses which dimesnion belongs to which part of the drawings
dimentioning tlabeled too close to the drawing of the building can be confuse as an object ....
Explain what kind of information you can gather and learn from existing maps for land surveying
history , underground infrastructure and facilities.
Elaborate in your own understanding why we need to draw to scale and what tools helps us to do so.
its not possible to draw life size of a large object such as a building. it will be too big a task to do so ad impossible to store or bring the drawing that size around. In order to draw to scale, accurate measurement of the sutdy object will be recorded manually and with the aid of a scale ruler, theis information ...
Elaborate what is Absolute ( mean ) Sea Levels, and explain why designers sometimes do not indicate building floor levels using Absolute ( Mean ) Sea Levels
Absoulute ( mean ) Sea Levels are averaged out of low and higt tide of the sea
sometime designer are not provided with the actual sea levels, namely Absolute ( mean ) Sea Levels hence designers will assign the Relative Sea Levels on the drawings to indicate the relative floor levels.
Elaborate how to conduct a linear measurements using pacing
Some building roofed set out roofs in metric, the vast majority still use imperial measurement due to the practice of roofing being a trade that is passed down from one generation to the next. give your own opinion on what kind of construction defects may occur with conversion of metric to imperial unit of measurement in this case.
most roofers will try and set out to the nearest quarters inch. if required they will work to n eighth of an inch, but few will work to sixteenth of an inch. with metric measurement most roofers will set out to the nearest 5mm. if they are required they will set out to 1mm. setting-out is multiple ....
