In conjunction with the Public Works Engineering Plan review Process, post construction record drawings are required for all Private Development projects. The intent of this document is to guide the designing Engineer, the Developer and their Consultants in providing the City with acceptable record drawings and survey information.

When the improvements intended for public dedication are substantially complete, the developer shall prepare “as-built” record drawings for the City using the current set of approved construction drawings, including all revisions and contractor’s field mark-ups. This drawing shall incorporate all changes made by both the Engineer and in the field during the construction process. Changes to be noted shall include changes in material, size, grade and location of utilities.

Preliminary (paper) Record Drawing Procedures

I: A licensed surveyor will physically survey all improvements associated with the approved construction plans and create an as-built topographical representation of the data.

II: The surveyed data will be incorporated into the preliminary record drawings and the Engineer will adjust the features in the record drawings to match the surveyed data. All surveyed elevations for sewer, storm and water will be shown on the record drawings by striking a single line through the design elevations and adding the surveyed “as-built” elevations. Horizontal locations will be indicated by using centerline station and offsets. All surveyed station and offsets will be shown on the record drawings by striking a single line through the design station and offsets and adding the surveyed station and offsets. The stationing will be based on the approved construction drawings. The Engineer will update both the plan and profile layouts with the surveyed data.

III: Prior to final walk-through, the engineer will compile the data and submit two copies of the preliminary (paper) record drawings to the City. The walk-through will not be scheduled until the paper record drawings are received.

Preliminary Record Drawing Submittal Requirements

• Two (2) paper copies (22”x34”) including all field changes made
• The preliminary record drawing will have all changes from the approved construction drawings clouded.
• This copy will include the field information supplied by the surveyor.

Final Record Drawing Procedures

After receiving approval of the preliminary paper record drawing from the City, the developer / designing engineer will submit the following:

Final record Drawing Submittals

• One (1) full size Mylar copy of the corrected record drawing. The final record drawing shall be signed and sealed by a licensed engineer and licensed surveyor. The mylar record drawing does not need to include detail sheets, erosion & sedimentation control sheets, or landscaping sheets. However, the cover sheet is required. The clouding of changes will be removed before the Mylar is submitted.
• One (1) electronic copy (AutoCAD 2014 format) which includes all of the surveyed data. The electronic record drawings shall contain the entire project in a single base drawing and include all sheet files.
• One (1) PDF copy of the final record drawing.
• One (1) paper copy (22”x34”) of the raw survey data signed and sealed from the surveyor shall be provided.
• One (1) Electronic CSV file in the following format: comma delimited coordinate file (CSV) of all points in the following format: Point Number, Northing, Easting, Elevation, and Descriptor. See descriptor code list below.

Requirements for Survey:

All features installed or modified with the construction shall be surveyed, including, but not limited to the following:
Water & Irrigation valves, risers & meters • Wells • Fire Hydrants & valves • PRV Vaults & Manholes • Sewer Clean-Outs • Sewer Stubs (Location & Depth) • Storm/Sewer Manholes (Lids & Inverts) • Top Back of Curb at ADA Ramps • Changes to Centerline design • Storm Drain Catch Basin Grates & Inverts • Monuments (Location & Elevations) • Storm Culverts (Location & Inverts) • Street Lights • Traffic Signal Poles & Control Boxes

Datum:

The topographic survey shall use NAD83 (2011) State Plane Coordinates for the Horizontal Datum and NAVD 88 Vertical Datum Geoid 12B, for control. A minimum of three (3) City of Richland approved control points shall be referenced on all construction and record drawings. The City Surveyor will delineate an acceptable list of existing monuments for collection.

Submittal Requirements and Deadlines:

Final walkthrough of the project and the associated punch list will be withheld until the preliminary paper record drawings are submitted for review as described above. Approval of the Final Plat and/or Final Acceptance of the project (certificate of occupancy) will be withheld until the Final record drawings and all other items noted above are received and accepted by the City.
