Based on comments from members of the Board, the following revisions have been made: 1) The term "Project Documentation Fee" has been revised to "Project Documentation Deposit." 2) The previous Draft noted the Project Documentation Fee (now Deposit) as "equal to 5 percent of the construction cost of the project." This clause has been clarified to read as: "equal to 5 percent of the construction cost of water and/or electric facilities to serve the project." The minimum deposit of $500 has been retained. 3) Concerns were raised regarding Developers who may not be able to provide electronic drawings. The following paragraph has been added to address those developers who do not have CAD capabilities and work strictly off paper/mylar drawings: "In the event that the Developer does not have the capability of producing electronic drawings, the District will accept the hard copy drawings as fulfillment of the As-Built requirements. However, the cost to the District for scanning, vectorizing and manipulating drawings to develop the required electronic data will be deducted from the Project Documentation Deposit." Page 1 of 2 Staff Report—District Policy Regarding As Built Drawings RECOMMENDATION That the Board adopt the revised Draft Policy Regarding As-Built Drawings. Attachment: Revised Draft Policy Regarding As-Built Drawings Page 2 of 2 TRUCKEE DONNER PUBLIC UTILITY DISTRICT POLICY REGARDING AS-BUILT DRAWINGS It is the policy of the Truckee Donner Public Utility District (District) to require the submittal of As-Built Drawings on all construction projects where facilities have been constructed and dedicated to the District. DEVELOPER RESPONSIBILITIES The details of the District's As-Built Drawing policy are outlined below. The policy makes numerous references to a party designated as the "Developer." The term "Developer" is intended to refer to the project developer or property owner who is responsible for the construction of the project and the required water and/or electric system improvements. The Developer may utilize other parties or designated agents such as contractors, architects or engineers to perform the duties and responsibilities outlined in this Policy. However, the failure of a third party to comply with this policy and its obligations shall not relieve the Developer of his responsibilities and shall not imply or impose any obligations upon the District. PROJECT DOCUMENTATION DEPOSIT At the time that the Developer signs the Development Agreement, the District shall impose a Project Documentation Deposit equal to 5 percent of the construction cost of water and/or electric facilities to serve the project. The minimum deposit shall be $500. This deposit shall be held by the District and refunded to the Developer upon successful completion of the As-Built Drawings as outlined below. The Developer shall not be due any interest on monies held by the District. AS-BUILT DRAWING PROCEDURES During the construction of the project, the Developer shall be responsible for maintaining a set of As-Built Drawings. The basis of the As-Built Drawings shall be the Construction Drawings as reviewed and approved by the District. 1) The Developer shall maintain one set of As-Built Drawings at the Project Site. On these, all project conditions, locations, configurations, and any other changes or deviations which may vary from the information represented on the original Construction Drawings shall be noted, including buried or concealed construction and utility features which are revealed during the course of construction. Special attention shall be given to recording the horizontal and vertical location of all buried utilities that differ from the locations indicated, or which were not indicated on the Construction Drawings. Drawings shall also note the location of any other buried infrastructure such as landscape irrigation, onsite drainage, lighting, hydronic heating, etc. As-Built drawings shall be supplemented by any detailed sketches as necessary or directed to fully indicate the facilities as actually constructed. As-Built Standards Page 1 TDPUD Policy Regarding As-Built Drawings 2) These master As-Built Drawings shall be maintained up-to-date during the progress of the Project. Red ink shall be used for alterations and notes. Notes shall identify relevant changes by number and date. 3) As-Built Drawings shall be accessible to District personnel at all times during the construction period. 4) The As-Built Drawings shall be submitted to the District upon completion of the project. Failure to submit complete As-Built Drawings may result in the partial or full forfeiture of the Project Documentation Deposit. A) Submitted As-Built Drawings will be reviewed by District staff for completeness, accuracy and format. If the As-Built Drawings are found to be acceptable, the Project Documentation Deposit will be refunded to the Developer. If the As-Built Drawings are considered unacceptable, they will be returned to the Developer for correction and resubmittal. B) If the corrected As-Built Drawings have not been resubmitted to the District after 60 days, the District will correct the As-Built Drawings as necessary to conform with this Policy. All costs incurred by the District to perform such work will be deducted from the Project Documentation Deposit and the remainder will be refunded to the Developer. The District may utilize either District personnel or outside contractors to complete the As-Built Drawings. The determination of which party is to perform such work shall be at the sole discretion of the District. C) In the event that the Developer fails to submit As-Built drawings within 60 days of acceptance of the facilities by the District, the, District will proceed with development of the As-Built Drawings. Such failure to submit As-Built Drawings shall result in the forfeiture of the entire Project Documentation Deposit, whether or not the Deposit is sufficient to complete development of the As-Built Drawings. AS-BUILT DRAWING FORMAT The Developer shall submit one hard copy of the As-Built Drawings. Drawings shall be 24" x 36" or 22" x 34" and shall be printed on bond paper. The Developer shall also submit electronic files containing the information depicted on the As-Built Drawings. In the event that the Developer does not have the capability of producing electronic drawings, the District will accept the hard copy drawings as fulfillment of the As-Built requirements. However, the cost to the District for scanning, vectorizing and manipulating drawings to develop the required electronic data will be deducted from the Project Documentation Deposit Electronic files shall conform to the following requirements: • File format shall be AutoCad Release 12-14 compatible. As-Built Standards Page 2 TDPUD Policy Regarding As-Built Drawings • Files shall be submitted on portable media such as 3.5-inch floppy diskette, ZIP disk or CD-ROM. The media containing the files shall become the property of the District, and will not be returned to the Developer. Files may be compressed in a format that is compatible with the WinZip decompression software. • The Developer shall submit all files used to produce the As-Built Drawings. Drawing files may utilize external references to reduce file size. However, all such reference files shall be included in the submittal. • Drawing layer structure shall be as given in Table 1. The Developer may use any combination of other layer names as desired for other elements depicted in the drawings. However, the relevant infrastructure system facilities shall appear on the designated layers. If certain facilities indicated by a given layer are not included as part of the project, the corresponding drawing layers may be purged from the drawing file. Table 1.
