Record drawings (as-builts) are required to provide a means of schematic verification that the intent of the approved engineering design has been met, thereby substantiating that the health, safety, and welfare aspects of the engineering design have been adequately provided by the construction of the project. Secondly, record drawings serve as a reference tool for future location and maintenance operations. The following requirements will be applied to each set of record drawings developed for the City:
A. General Record Drawing Requirements:
1. The first sheet of the set will have a vicinity map in the upper right-hand corner.
2. Record drawings shall be submitted as revisions shown on the original engineering plans and as AutoCAD (current version) files. Record drawings will have the original data lined through and the record data added to the drawing. At no time will the original data be accepted as the record data.
3. All record drawings for major projects are required to be twenty four inches by thirty six inches (24" x 36") and shall bear the name, address, and telephone number of the firm preparing the drawings and the date the record data is added to the original drawings via the revision block.
4. Surveyor’s/engineer’s statement (with embossed or wet seal and with original signature on each sheet) shall verify that the record drawings reflect the true conditions in the field.
5. “Record Drawing” shall be labeled on each sheet in one inch (1") high letters.
6. Street names shall be shown on all streets.
7. If the utility system is to be private (not to be dedicated to local authority), then indicate such on each sheet.
8. The location and elevation of the bench marks referenced will be shown on the drawing (and should be the same bench mark datum. as the original approved design plans). If the referenced bench marks are not within the project limits, then complete descriptions of locations must be provided.
9. Show all easements within the project limits on the record drawings.
B. Detention Pond Record Drawing Requirements:
1. Topographic map of the detention area.
2. Spot elevations on top of bank to confirm minimum design bank elevations as well as spot elevations on any overflow weir.
3. Observed water elevation at date of the record drawing for wet bottom basins.
4. Location of top of bank and existing water edges at time and date of taking elevations.
5. Spot elevations on the bottom of dry bottom basins, or, if requested by the Subdivision Administrator, for wet bottom basins.
6. A stage/storage table showing the design and as-constructed pond volumes and release rates.
7. A signed/sealed statement by a professional engineer that the detention pond(s) provides the required detention storage and does not exceed the allowable outflow rate(s) per the approved construction plans and hydrology study. If significantly different than the approved drawings (as determined by the Subdivision Administrator), the engineer must submit a revised hydrology study using the as-constructed conditions in order to document this statement.
C. Water System Record Drawing Requirements:
1. Locate all valves, services (b-boxes), and fire hydrants in two (2) directions (station and offset).
a. Locations shall be perpendicular to the right-of-way and parallel to the water main.
(1) Lot lines may be used to locate water services.
(2) Permanent structures that are properly located may also be used.
(3) Radial ties are not acceptable.
b. All horizontal distances shall be shown to the nearest foot. All vertical distances shall be shown to the nearest tenth of a foot.
2. Show all materials, sizes, and types of valves, pipes and special fittings (crosses, tees, reducers, etc. - not elbows).
3. Elevations shall be given for the top of all structure frames/lids and for the top of all pipes entering/exiting each structure.
4. Special detail drawings will be required where installations are not shown on approved engineering drawings for whatever reason or where required for clarity.
5. Show location and elevation for pipes where bury depths are greater than six feet (6').
6. Details for water services deviating from typical installation details of the approved engineering plans shall be noted on the record drawings (i.e., instances where the corp stop location is not evident).
D. Sanitary Sewer System Record Drawing Requirements:
1. Locate all wyes, cleanouts and manholes in two (2) directions in the same manner as subsection B of this section.
2. Horizontal dimensions shall be to the nearest foot. Vertical elevations shall be to the nearest hundredth of a foot.
3. Identify the length, size, material, and slope of all pipe (i.e., 300 feet of 8" PVC SDR 35 at 0.4%).
4. Elevations shall be given for the top of all manhole covers and for the inverts of all pipes entering/exiting each manhole.
5. Service laterals are to be identified with location of end of service/plug (station and offset measured upstream).
6. Details for drop manholes deviating from the details on the approved engineering plans shall be indicated on the record drawings.
E. Force Mains Record Drawing Requirements:
1. Locate all valves and manholes in two (2) directions in the same manner as subsection B of this section.
2. Show all materials, sizes, and types of valves, pipes, and special fittings (crosses, tees, etc. - not elbows).
3. Elevations shall be given for the top of all structure frames/lids and for the top of all pipes entering/exiting each structure.
4. Special detail drawings will be required where installations are not shown on approved engineering drawings for whatever reason or where required for clarity.
F. Lift Station Record Drawing Requirements:
1. Wet well and valve vault size and location shall be indicated along with wet well high and low water levels.
2. Elevations for top, bottom, inverts, adjacent ground and type and size of lines and fittings for all lines entering or leaving the wet well and valve vault shall be indicated.
3. Any amended schedules which show pump, motor and electrical data shall be indicated.
G. Storm Sewer System Record Drawing Requirements:
1. Elevations shall be given for the top of all storm sewer structure frames/lids and for the inverts of all pipes entering/exiting each structure.
2. Any on-site field tiles which remain on-site must be identified on record drawings.
3. Identify the length, size, material, and slope of all pipe (i.e., 300 feet of 12" RCCP at 1.0%).
4. Horizontal dimensions shall be to the nearest foot. Vertical elevations shall be to the nearest hundredth of a foot.
5. Provide elevations and cross-sectional information, as well as slope, on all ditches, canals, etc.
H. Street Lighting Record Drawing Requirements:
1. Provide horizontal ties for light foundations and control cabinets as referenced to the approved plan stationing or coordinates.
2. Service cables and service transformers shall be depicted in schematic form.
I. Electronic File Record Drawing Requirements: Include AutoCAD compatible version of all record information as described in section 13-5-10 of this title.
