DESIGN
1 Complete facility with future scope (if any) as per the Project scope is covered in Drawing.
2 Plant North, True North, wind direction & wind rose (if applicable) are shown. Angle between Plant and True North isshown.
3 Datum point for plant (relative) co-ordinate system is defined and is located in the S-W corner of the plot (unless a different location is specified in theProject documents).
4 Plant (relative) co-ordinate system is so defined that the co-ordinates within the plot area have positive values.
5 The true geographical co-ordinates (UTM) of the datum point are indicated either at the datum point or in thenotes.
6 Coordinate gridlines are shown, where applicable, along with northing/easting values.
7 Reference (distances/co-ordinates) with existing facilities is given.
8 Grade levels for all indicated areas are given and are checked with the Civil grading plan.
9 Relation of plant grade levels with reference (datum) level (e.g. mean sea level) is indicated.
10 Security wall/fencing around the plant is shown.
11 Main gates with security room/guard house are shown.
12 Separate gates are provided for personnel, trailer tanker & vehicle movement, if applicable.
13 Separate fencingis provided for restricted areas, e.g. flare stack, pig launcher/receiver, metering station, etc., ifapplicable.
14 Emergency exits and assembly points (muster stations) are shown.



15 Main roads and secondary roads are located with centre line and coordinates/locating dimensions. Road and shoulder widths are checked as per projectrequirements.
16 Availability of access to heavy equipment for erection purpose is checked.
17 Adequate access roads are provided around process units and tank farms.
18 All units/areas are indicated by the respective area code, name or tag, e.g. UTA, Utility Area, Unit-109, etc.
19 Distances between units are given.
20 Minimum distances between equipment/buildings/units as per the applicable codes/Project standards are checked (at least for IFAissue).
21 Flare stack is located considering the prevailing wind direction in agreement with HSE.
22 Sterile zone radius is shown for flare stack and no other equipment is located within this zone.
23 Safety distance/radius is shown for fired heater/hazardous equipment, if applicable.
24 Corridors for piperacks (including structures for expansion loops) and sleepers are shown (dimensions, grid nos. notrequired).
25 Major storm water drain trenches and major UG corridors (for UG piping, pipelines, cable trenches, etc.) are shown, asapplicable.
26 Equipment list is given in the drawing (unless otherwise decided for the Project). The list includes at least the major equipment and the same equipmenttag nos. are indicated in the drawing.
27 Equipment and vendor package outlines are shown and their tag nos. are checked with the project EquipmentList/PFDs/P&IDs.
28 Plant buildings/shelters are shown as blocks (outline periphery only – dimensions not required).
29 Non-plant buildings (Administration, Canteen, Warehouse, etc.) are shown as blocks, as applicable (outline periphery only – dimensions notrequired).
30 Dyke walls are shown around tanks (wherever applicable).
31 Future requirements (e.g. future units/equipment, expansion area etc.) are provided and clearly marked.
DRAFTING
32 The drawing border conforms to the Project specifications or Company standards, as applicable.
33 Drafting conventions e.g. font types/sizes, text styles, line types, coordinate/dimension styles, layer structure, etc. are as per the Project specifications orCompany CAD standards, as applicable.
34 Drawing title, drawing number and revision number in the title block are as per the TDR.
35 Electronic file name is indicated at appropriate location on the drawing.
36 Revision block contains initials of the originator, checker and approver (both Discipline & Project).
37 Drawing scale is stated in the title block and graphic scale (bar scale) is shown.
38 The drawing scale conforms to the Project specifications or Company standards, as applicable.
39 All general notes are checked and the units for dimensions, coordinates & levels are given in the notes.
40 Legend for applicable symbols is shown (e.g. new/existing facilities, scope cloud, etc.)
41 Reference Drawing numbers and titles are listed and checked.
42 Status stamp (e.g. “For Approval”, “For Construction”) is shown.
43 Revision clouds, along with revision number triangles are marked properly, if applicable.
44 “Hold” clouds, if applicable, are properly marked and the list of “Holds” is indicated.
45 Location map/key plan is shown (if applicable).
46 All tags are clearly marked and are legible.
47 Drawing extracted from 3D CAD model is not manually edited.
