Section 02700.1.03.C - add the following:

"6.	POST-INSTALLATION SURVEY - Television inspection shall be completed by the Developer/Contractor prior to acceptance of the line and/or placement of the bituminous wearing course. During the eighteen-month of the warranty period, perform a second televised inspection.
	1.	Procedure:
		a.	CCTV:
			i.	Mainline:
				1.	Before TV inspection work, inspect sanitary sewer line from manhole to manhole, preferably upstream to downstream, one section at a time.
				2.	Maintain sanitary sewer main isolation by plugging or bypass pumping while camera is moving and recording if depth of flow in sewer requires isolation.
					a.	Plugs: Secured to remain in place during inspection.
					b.	Conduct operations to prevent building backups and sewer overflows.
					c.	Be responsible for cleanup, repair, fines, property damage costs and claims for any sewage backup, bypass spillage or sanitary sewer overflow.
		b.	Placement of Camera:
			i.	Manhole:
				1.	Place at center of manhole and commence video before entering pipe.
				2.	Start footage counter at center of manhole.
			ii.	Mainline: Mount on a transport platform that will keep it centered along longitudinal axis of sewer mainline and above water.
		c.	Operation of Camera:
			i.	Show inside of manhole walls, manhole channel, and pipe connection to wall at both upstream and downstream manhole and lateral connections.
			ii.	Move through line at speed no greater than 30 feet per minute stopping for minimum 10 seconds to record lateral connections, mainline connections, defects, and features and points of interest.
			iii.	Maintain technical quality, sharp focus, and distortion free picture.
			iv.	Videotape a section of sewer in its entirety with no breaks or interruptions.
			v.	Pan, tilt, and rotate as necessary to best view and evaluate lateral connections, defects, features, and points of interest.
			vi.	Use power winches, powered rewinds, tractors, or other devices that do not obstruct camera view or interfere with proper documentation of sewer conditions to move camera through sewer.
				1.	Whenever non-remote-powered and -controlled winches are used set up telephones or other suitable means of communication between manholes to insure good communications.
			vii.	Use hydraulic jet nozzle if necessary to remove standing water from line.
			viii.	Eliminate steam in line for duration of inspection:
				1.	Utilize blower as needed to defog sewer line.
			ix.	Measurement for location of defects and service laterals:
				1.	At ground level by means of Borough's Engineer-approved footage counter or metering device.
				2.	Measurement meters: Accurate to 0.2 foot over length of section being televised.
				3.	Use measuring target in front of television as exact measurement reference point.
			x.	Movement of Television Camera:
				1.	Mainline:
					a.	Stop camera at service connections and inspect lateral with pan and tilt camera.
					b.	At active service connections where flow is discharging.
						i.	Identify building address and confirm that laterals are active by obtaining flush, with or without dye, of property owner's commode or by using outside cleanout, if available.
						ii.	If no flows are being discharged from building, consider observed flow as infiltration/inflow.
			xi.	Identification of Defects:
				1.	If roots, sludge, or sediment material impedes inspection withdraw CCTV equipment and perform inspection from opposite end.
					a.	Extract camera stuck in sewer line.
					b.	When additional obstructions are encountered after redeployment of equipment, and no means are available for passing obstructions, remand to Borough for resolution.
	2.	Field Documentation:
		a.	Mainline:
			i.	Submit original records, logs, DVDs, CD-ROMs, and electronic data for sanitary sewer line inspection to Borough within five working days.
			ii.	Include, but not be limited to following information.
				1.	Project number.
				2.	Basin name.
				3.	Owner.
				4.	Date, time (begin to end inspections).
				5.	Weather condition.
				6.	Operator name.
				7.	QA reviewer name.
				8.	DVD/CD number and index.
				9.	Address of upper most lateral.
				10.	Manhole number to manhole number.
				11.	Manhole depths.
				12.	Length of pipe segment.
				13.	Direction of CCTV (upstream or downstream).
				14.	Pipe size.
				15.	Pipe material.
				16.	General physical conditions.
				17.	Footage locations, clock position, descriptions, and estimated leakage rates for visible point sources of infiltration/inflow.
				18.	Footage locations, clock position, and descriptions for lateral connections and estimated flow from laterals.
				19.	Footage locations, clock position, and descriptions of defects such as obstructions, root intrusion, blockages in pipe, deteriorated joints, offset joints, holes, breaks, cracks, collapses, bends or sags in alignment, or protruding lateral connections.
				20.	Footage locations, clock position, and descriptions of other defects, features and points of interest found.
				21.	Whether CCTV was complete or incomplete.
				22.	DVD/CD-ROM Recording/Playback:
					a.	At same speed that it was recorded.
					b.	Supply slow motion or stop motion playback features.
					c.	Once recorded, DVD/CD-ROM becomes property of the Borough.
					d.	Have DVD/CD-ROM and necessary play-back equipment readily accessible for review by Borough's Engineer during Project.
				23.	Observation terminology utilized during audio narration: Follow the Borough approved terminology.
				24.	DVD/CD-ROMs displaying poor video quality refers to, but is not limited to grease or debris on lens, camera under water, image too dark, washed-out, distorted, or out of focus, lines improperly cleaned, and poor/no audio.
					a.	Re-televise line if necessary and resubmit DVD/CD-ROM."
