Shop drawings are detailed illustrations necessary for site engineers to accurately implement designs, differing from design drawings that outline general positions without specifics. The contractor is responsible for creating these drawings, with consultants approving or creating them in complex projects. The document outlines the steps for making shop drawings using AutoCAD 2015, including detailed processes for outlets, switches, circuits, and necessary dimensions.

2.  What are shop drawings and why we need it?
 The difference between design drawings and shop
drawings.
 How to make shop drawings.
 The steps of making shop drawing.

3.  Shop drawings are more detailed drawings which are
needed to help the site engineer to implement the
design properly.
 The contractor is the responsible for making the shop
drawings and the consultant has to approve it.
 In some cases the consultant makes the shop drawings
according to the contract.

4.  The design drawings are drawings which focus on the
positions of electrical outlets without determining the
real passes of electrical wiring.
 In simple projects we may not need shop drawings.
 Shop drawings are needed more in projects which
contain relatively complex electrical works.

5.  Shop drawing mainly are derived from design drawing.
 We will navigate through the steps of making shop
drawings in the following slides…
 We will take lighting drawings of a building as an
example.
 We will use AutoCAD 2015.

6.  First we should copy the design drawing’s outlets into the
new file of the shop drawing.
 Then replace these blocks by new outlets which are used
in shop drawings.
 Edit the blocks of the switches by adding back boxes to
them, the same thing for the wall mounted lighting
fixtures.
 For the wall mounted outlets of the exhaust fans, replace
them with junction boxes.

7.  Start to make the wiring between the outlets and stick to
the circuits existed in the design drawings.
 Connect between each switch and its related outlets.
 Put the circuit number on each outlet.
 Also make the connection between each circuit and the
distribution board.
 Put the control letters on each outlet.
 Connect between each switch and its related outlets.

8.  Details are texts put on each plotted line to show its
circuit number, wire cross section and conduit diameter.

9.  Dimensions are put to show the distance between each
outlet and the nearest concrete column and the distance
between each two adjacent outlets.

10.  If the number of bends of each branch circuit achieved 3
bends, you should put a pull box.
