5 Main roads and secondary roads are located with centre line and coordinates/locating dimensions.
6 Road width and elevations are given.
7 Road crossings, e.g. culverts, casing pipe, duct banks are shown wherever applicable.



8 Crash barriers are shown wherever required.
9 Emergency exits are shown.
10 Availability of access to heavy equipment for erection purpose is checked.
11 Hard stand areas for heavy equipment is properly marked and located (if applicable).
12 Equipment list is given in the drawing and equipment tags marked in the plot match with the list.
13 Equipment/packages and their tag nos. are checked with the Project Equipment List/P&IDs.
14 All equipment/packages are shown with locating coordinates/dimensions and elevations (centerline, BTL, u/s of base plate, etc.) and the elevations arechecked wrt P&ID/Process requirements.
15 All equipment sizes are checked with mechanical data sheets/Vendor drawings.
16 Auxiliary equipment (e.g. API seal plans, LO coolers/skids, etc.) of pumps/compressors and other packages are shown as per Vendor data.
17 Multiple equipment having tag nos. with suffixes like A/B/C (e.g. multi-bay air-coolers, pumps, etc.) are clearly identified and tagged as per Project Equipment List/P&IDs.
18 Fixed/sliding saddle locations for horizontal vessels and heat exchangers are indicated and the direction of slope is indicated for sloping vessels.
19 Piperacks are shown with the module breaks and tag nos. (as per Civil drawings) and the locating coordinates, column to column dimensions and widths are indicated.
20 Pipe rack TOS elevations are clearly marked, esp. in case of multi-tier racks. Sectional details are provided wherever required and space requirement for cable trays is marked.
21 Pipe tracks/sleepers are shown with locating coordinates/dimensions, widths, TOS elevations and tag numbers (if applicable).
22 Minimum distances between equipment/buildings/units as per the applicable codes/Project standards are checked.
23 Laydown/dropdown areas, exchanger tube removal areas, equipment maintenance/crane access areas are shown wherever required.
24 The requirement of monorail/EOT/HOT cranes/pipe davits, if any, for compressor shelters/pump houses/platforms, etc. is shown with elevation & capacity.
25 Davit location/orientation on heavy equipment/columns/heat exchangers, etc. is checked for access/maintenance handling.

29 Floor plans/sections of shelters/technological structures are shown where necessary. Equipment and platforms within shelters are shown.
30 Structural grid numbers of pipe racks, buildings and shelters are shown. Grids numbers are marked with numerals in one direction and alphabets in the other direction as per the project requirements.
31 Future requirements (e.g. future units/equipment, expansion areas, etc.) are provided and clearly marked.
32 Underground facilities (e.g. buried vessels, u/g storage pits, etc.) are shown. Items like valve pits, OWS manholes, etc. are shown in model extracteddrawings (dimensions/coordinates are not required).
33 Storm water drain trenches and major UG corridors (for UG piping, pipelines, cable trenches, etc.) are shown (dimensions/ coordinates are not required). Foundations below ground need not be shown.



34 HSE requirements (if any) for staircase/escape route for tech. structure and pipe rack platforms are checked.
35 Sterile zone radius is shown for flare stack and no other equipment is located within the sterile zone.
36 Safety distance/radius is shown for fired heater/hazardous equipment (if any).
