PART 1 GENERAL

1.01 DESCRIPTION

A. Contractor shall utilize a professional electrographer who is actively engaged in preparation of color DVD or CD recordings for municipal construction projects, similar to the Work included in this Contract.

1.02 QUALITY ASSURANCE

A. Owner may make such investigations as Owner deems necessary to determine the ability of the electrographer to perform the work. Contractor shall furnish to Owner all such information and data for this purpose as requested by Owner. Owner reserves the right to reject any electrographer if the investigation of such electrographer fails to satisfy Owner that such electrographer is properly qualified to carry out the work specified herein. Upon rejection of an electrographer by Owner, Contractor shall engage the services of another electrographer, who shall be subject to a similar review and approval process by Owner specified herein, prior to approval by Owner.

B. No construction shall begin prior to review and approval of the DVD’s and/or CD’s covering the existing conditions of the entire project area by Owner’s Engineer. Any recordings that are unacceptable to Owner’s Engineer shall be re-recorded by the electrographer at no additional charge.

All DVD’s and/or CD’s and written records shall become the property of Owner, upon approval and acceptance.

1.03 SUBMITTALS

A. Two (2) complete copies of project DVD’s and/or CD’s shall be provided to Owner’s Engineer for approval.

1.04 JOB CONDITIONS

PART 2 PRODUCTS

2.01 EQUIPMENT

A. Mobile Unit

When conventional wheeled vehicles are used, the distance from the camera lens to the ground shall be at least twelve (12) feet in order to ensure that the proper perspective is obtained. In some instances, recorded coverage will be required in areas not accessible by conventional wheeled vehicles. In that case, such coverage shall be obtained by walking or special conveyance approved by Owner’s Engineer.

B. Camera

Video output from the camera used must be capable of producing NTSC-525 lines/60 field. Video output shall provide resolution in the “Y” channel, minimum 500 TV lines at center, utilizing a bias lit beam split prism, in combination with a professional and/or industrial charge-coupled device (CCD) camera, for optimum color imagery and minimum lag through 3.1 meter-candles (10 foot-candles), with geometric distortion not to exceed 1.5% of picture height at any point in the picture area.

C. Audio-video recording medium

Contractor’s electrographer shall utilize professional-grade DVD or CD recording equipment in the preparation of the project recordings. Contractor’s electrographer shall provide a sufficient quantity of DVD’s or CD’s to properly and completely record the work. DVD’s and/or CD’s shall become the property of Owner at the completion of the project.

B. Video

Periodic transparent alpha-numeric information consisting of the project name, description of area covered, direction of travel, viewing side, etc. shall appear on the screen. All video recordings shall, by electronic means, display continuously and simultaneously generated transparent digital information to include the date and time of recording. The date information shall contain the month, day and year (i.e. 4/15/11) and shall be placed directly below the time information.

C. Audio-Video Tracks

The DVD or CD shall consist of both visual and audio information, recorded simultaneously. Tracks shall consist of original live recordings and shall not be copies of previous recordings. Audio track shall contain the narrative commentary of the electrographer, recorded simultaneously with his fixed elevation visual record of construction. Owner’s Engineer shall have the option of recording comments on the audio track.

PART 3 EXECUTION

3.01 DVD OR CD COVERAGE

A. The entire project site shall be recorded. The zone of influence shall be extended a minimum of 15 feet from each side of each roadway designated to receive a mill and overlay.

B. Recorded coverage shall include all surface features located within the above mentioned area supported by appropriate audio description. Audio description shall be made simultaneously with video coverage. Such coverage shall include, but not be limited to, all existing driveways, road surface, sidewalks, signs, drainage culverts, visible utilities, retaining walls, railroad grade crossing features, parking areas, curbs, and drainage ditches located within the zone of influence.

C. When applicable, house numbers shall be used to identify houses or other buildings, in such a manner that proposed system structures (i.e. manholes) may be located by reference.

D. The rate of speed in the direction of travel of conveyance shall not exceed 48 feet per minute.

Panning rates and zoom rates shall be controlled sufficiently so that object clarity will not be obscured during playback.
