requirements contracts for engineering design and related services ...

c. The Consultant shall submit to the Commissioner all original survey field notes.
8. The Utility Profile shall be plotted under the corresponding Plan view.
9. Where the work requires only one sheet, the sheet shall be arranged so that sufficient space is available for notes
legend, and key plan.
10. The Plan and Profile drawings shall show a match line to tie together areas depicted on different sheets.
11. Where more than one sheet is required, the sheets shall be numbered consecutively.
12. All individual locations shall show the North Meridian oriented to top of drawing or to right margin of the drawing.
J. CLEAN BASE PLANS
1. The Consultant shall prepare Clean Base Plans - which shall be graphic representation of the project that is suitable
for use as a base plan set for the development of Schematic, Preliminary, and/or Final Contract Documents.
Graphic elements that shall be shown include mapped right-of-way lines (including lengths, block interior angles and
ROW widths, Legal Grades), property lines, possession lines, lot lines, Block and Lot numbers, house number,
buildings (including number of stories, type and usage), ancillary development, street/sidewalk hardware (manhole
covers, poles, etc.), existing curblines and edges of pavement, bulkhead and pier head lines, limits of wetlands,
easements, trees, theoretical centerline baseline with stationing, and north arrow.
2. Text elements shall be limited to street names, stationing, and other “NECESSARY” items. Generally, elements to
be excluded include, but are not limited to: elevations, lane lines, redundant text, “condition” text. There shall be no
labeling of walks, grass, etc. The Consultant shall submit a “one-sheeter” sample for approval prior to the
development of the Topographic Program. No elevations will be shown on this plan. The base map shall be plotted
on a separate 28”x40” (F) size with a horizontal scale of 1”=30’.
K. TOPOGRAPHICAL PLAN
1. The Topographical Plan(s) shall be plotted by superimposing the Topographic Survey data on to the Clean Base
Plan.
2. Inverts and Rim (center of the cover) elevation shall be shown for sewers and catch basins. All street surface
elevations as described in section C.1 “f” shall be shown. Elevations shall be shown on City owned “irons” only (not
on private utilities). Legal grades shall be shown. Separate spot elevation drawings shall be produced where a full
data plotting would produce a “crowded” presentation - as directed by the City.
3. Topographical Plan(s) limits shall be coincident with the topographic survey limits and as herein defined - including
the nearest connected manhole outside the project limits.
4. The Topographical Plan(s) shall be of 28”x40” (F) size, and the scale of the drawings shall be 1”=30’. The scale
shall be shown below the Plan view.
L. UTILITY PLAN AND PROFILE
1. The Utility Plan(s) shall be plotted by superimposing the Utility data on the Base Plans excluding all shown
elevations in the Plan view (except for Legal Grades, which must be shown both in Plan and Profile view).
2. The Utility Profile(s) generally shall include cross sections of all sewer manholes, and all sewer pipes which are
shown on the utility plan (excluding those on side streets). In addition, rim and invert elevations for all shown
manholes, and invert elevations, sewer type, size, and pipe material for all shown sewer pipes must be indicated.
Legal grade and roadway center line profiles must also be shown on the utility profile. .
3. Sewer and Water utilities shall be identified by approved line type with the following information identified: type of
utility, size, configuration, etc.
4. Existing and/or “From Record” Sewer and Water utility lines shall be indicated and plotted to scale with approved
line types.
5. Inverts and Rim elevation shall be shown for sewers in Profile view only.
6 Profile(s) limits shall be coincident with the topographic survey limits and as herein defined.
