SCOPE OF WORK AND STANDARD SPECIFICATIONS
For: Cleaning and Televising Sanitary Sewers
SS -01. CONSTRUCTION PERIOD AND REQUIREMENTS Burlingame shall
CCTV inspect and clean approximately 30,000 linear feet of sanitary sewer line in FY
06/07 and complete approximately 60,000 linear feet of sanitary sewer line within each
subsequent fiscal year of the agreement. The exact footage completed may vary
according to logical termination points as agreed upon by both parties relevant to sub -
basin boundaries, accessibility, weather and availability of manpower, equipment, and
budget, and mix of sewers in easements or in the streets.
SS -02. COORDINATION Burlingame shall accommodate the Town
representative who may be performing manhole inspections and monitoring
Burlingame's video inspection activities. Burlingame shall provide viewing access to a
video monitor during the inspection. Town representative shall direct Burlingame to
adjust camera speed and picture quality to allow adequate time to view any defects
observed.
SS -03. HEALTH AND SAFETY All work shall be done in a safe, workmanlike
manner. Work performed, methods, and equipment used shall be in conformance with
the prevailing State and Federal Occupational Safety and Health Act and the applicable
portions of Section 7 of the Standard Provisions. Costs from delays and losses due to
operations not in conformance to these acts, specifications, or stoppages by OSHA
inspectors or the designated representative, as a result of non-conformance, shall be
solely borne by Burlingame.
Work shall occur only between the hours of 7:00 a.m. and 3:30 p.m., Monday
through Friday, unless the Director of Public Works or his/her designated
representative grants an exception. Exceptions will be considered only when, in the
opinion of the Director, work during the above period would inconvenience the public
and neighboring residents more than working at other hours or on weekends.
Exceptions will not be granted merely to expedite the work.
The entry of manholes, for cleaning and inspection, shall be avoided when
possible. Use of mechanical devices or equipment to remove material from manholes
and to install or remove the video camera should be utilized whenever possible.
A. A gas detector that monitors for safe oxygen levels, hydrogen sulfides,
and combustibles shall be on-site at all times. The detector shall be used before
manhole lids are removed and during any manhole entry. Other manhole entry
equipment that shall be on-site shall include: (1) harness, (2) rope, (3) tripod & winch,
(4) ventilators, (5) hard hats, and (6) other personal protective equipment.
B. If entry is necessary all manholes shall be treated as confined spaces. All
Cal -OSHA and Title 8 requirements shall be followed.
C. Traffic control measures shall be in accord with Caltrans regulations.
Traffic control diagrams shall be submitted for a typical residential street and for a lane
closure on a typical arterial roadway.
D. Proper traffic control equipment shall be on-site and shall include: (1) High
rise warning signs, (2) barricades, (3) 28" tall cones, and (4) reflective sleeves.
SS -04. WORK COORDINATION AND NOTIFICATIONS Burlingame shall
meet with the Town's Sewer Supervisor or their designated representative on a weekly
basis, at a minimum, to discuss and agree on the general area where work will occur for
that week. Town will be responsible for providing notice to residents/owners of private
property prior to accessing manholes in public utility easements as Town deems
necessary and appropriate.
SS -05. CONSTRUCTION WATER A permit for use of Town water is required.
Burlingame shall be responsible to make proper arrangements for metering from the
Town by contacting the Water Department at (650) 375-7444. Burlingame shall provide
all necessary piping and appurtenances, including pumps, to convey water to the work
site. The costs of water required for this project shall be borne by the Town and
considered as necessary to the completion of work and result in no additional cost to
Burlingame. A meter with a backflow preventer adaptable for Town of Hillsborough fire
hydrants will be used for water supply — use only hydrants that are painted green or
blue to fill hydro jet. If hydrants are not marked in colored paint, Burlingame crews will
contact Town representative for direction as to which hydrant(s) may be used.
Burlingame crews may bring City water with them to start the workday. Such water will
not be billed to Town and conversely Burlingame will charged for Town water used for
services provided within this agreement.
SS -06. CLEANING AND PRELIMINARY INSPECTION Burlingame must
furnish all labor, materials, and equipment necessary to remove foreign materials frorn
the Sanitary Sewer lines prior to inspection by closed-circuit television (CCTV).
Burlingame must lease or own sewer -cleaning equipment. Following is a list of cleaning
equipment that will be allowed or not allowed depending upon the application:
A. High -Velocity Hydraulic (Hydro -Cleaning) Equipment: All high -velocity
sewer cleaning equipment shall be constructed for ease and safety of operation. The
equipment shall have a minimum working pressure of 2000 psi at a 30-gpm rate. The
nozzles shall be capable of producing a scouring action, in the lines designated to be
cleaned, to remove debris and sand from the flow line. Equipment shall also include a
2
high -velocity gun for washing and scouring manhole walls and floors. The gun shall be
capable of producing flows from a fine spray to a solid stream. The equipment shall
carry a nominal 600 gallon minimum water tank, auxiliary engines, pumps, and
hydraulically driven hose reel. The equipment shall have a minimum of 650 feet of
high-pressure hose.
B. Hydraulically Propelled Equipment: Sewer balls or movable dam shall not
be used.
C. Root Removal Equipment: Chain flail nozzles shall be used for root
removal. No chemicals will be allowed for use in root removal.
SS -07. SANITARY SEWER CLEANING The designated Sanitary Sewer
sections shall be cleaned using hydraulically propelled, high -velocity jet equipment.
Selection of the equipment used shall be based on the conditions of the lines at the
time the work commences. The equipment and methods selected shall be in
accordance with Section SS -06 of these Standard Specifications. The equipment shall
be capable of removing dirt, grease, rocks, sand, and other materials and obstructions
from the sewer lines and manholes. If cleaning of the entire section cannot be
successfully performed from one manhole, then the equipment shall be set up at the
destination manhole and cleaning attempted again.
SS -08. CLEANING PRECAUTIONS During sewer cleaning operations,
precautions shall be taken in the use of cleaning equipment, so as to prevent damage
to the existing pipe and manholes. Care must also be taken to prevent flooding of
houses and toilets. Burlingame is responsible for cleaning of any flooding incidents to
properties that occur during these operations.
SS -09. MATERIAL REMOVAL All sludge, dirt, sand, rocks, grease, roots, and
other solid or semi-solid material resulting from the cleaning operation shall be
removed at the downstream manhole of the section being cleaned. Passing material
from manhole to manhole will not be permitted.
SS -10. DISPOSAL OF MATERIALS All solids or semi-solids resulting from the
cleaning operations shall be removed from the site and disposed of at the Burlingame
Wastewater Treatment Plant, located at 1103 Airport Blvd, Phone # (650) 342-3727.
The Treatment Plant will need one day advance notice that the Burlingame will need to
dump. Prior to dumping, Burlingame shall have dewatered the material accumulated
from cleaning operations.
SS -11. ACCEPTANCE OF SERVICES Acceptance of Sanitary line cleaning
shall be made upon demonstration, through the television inspection, that the line has
been cleaned sufficiently to allow determination of its condition. Costs for Sanitary line
cleaning shall be included in Burlingame's unit price for television inspection. No
additional compensation shall be made.
N
SS -12. TELEVISION (CCTV) INSPECTION Burlingame shall furnish all labor,
materials, and equipment necessary to perform closed circuit television inspection, in
color, of the Sanitary lines listed. The inspection shall be done one line section at a
time and the flow in the section being inspected shall be suitably controlled as
specified.
SS -13. CCTV EQUIPMENT The television camera used for the inspection
shall be one specifically designed and constructed for operation in connection with
sewer inspection. It shall be a color camera, operative in 100 percent humidity
conditions and shall have a 360 -degree radial view rotating head. Lighting and camera
quality (3 lux) shall be suitable to allow a clear in -focus picture of a minimum of six
lineal feet of the entire inside periphery of the sewer pipe. Lighting for the camera shall
minimize reflective glare. To insure peak picture quality throughout all conditions
encountered during the survey, a variable intensity control of the camera lights and
remote control adjustments for focus and iris shall be located at the monitoring station.
Focal distance shall be adjustable through a range from six inches to infinity.
Continuously displayed on the monitors shall be: (1) date of the survey, (2) number
designation of the upstream and downstream manholes corresponding to the line
section being surveyed, and (3) a continuous forward and reverse readout of the
camera distance from the manhole of reference. The remote reading footage counter
shall be accurate to 2/10 (two-tenths) of a foot. The camera, television monitor, and
other components shall be capable of producing a minimum 500 -line resolution color
video picture.
SS-14.CCTV OPERATION The camera shall be moved through the line in either
direction at a uniform rate, stopping when necessary to permit proper documentation of
the sewer condition. In no case will the television camera be pulled at a speed greater
than 60 (sixty) feet per minute. Manual winches, power winches, TV cable, and
powered rewinds or other devices that do not obstruct the camera view or interfere with
proper documentation of the sewer conditions may be used to move the camera
through the sewer line. A self-propelled tractor unit may be necessary for lines with
only one entrance access or to prevent set up at high traffic intersections. As the
camera approaches a lateral connection or substantial defect, the camera progress
shall be halted and the camera lens panned to further view the lateral pipe and
connection or defect to thoroughly evaluate its condition.
A. If during the inspection operation, the television camera will not pass
through the entire line section as a result of offset joints, broken pipe or other
obstructions, then the Burlingame shall set up his equipment so that the inspection can
be performed from the destination manhole. If the camera then fails to pass through
the entire line section, the Burlingame shall immediately notify the Town. In the case of
submerged lines or sags, Burlingame shall block the upstream manhole(s) and vacuum
clean or jet flush the line and proceed with the television inspection. In the event
Burlingame is still unable to televise the entire line and has demonstrated to the Town
that every reasonable effort has been made to clean the line for inspection, or to
reverse the camera path, then the Burlingame shall move on to the next set up. In
such case, Burlingame may bill the Town at the appropriate per ft. rate for 50' minimum
for each such set-up. This must be approved by Town representative. However, the
4
Town reserves the right to perform spot repairs to the line and have the Burlingame re-
inspect the line. Reverse taping segments shall be checked for total coverage of
manhole to manhole runs.
B. In the event sewage line flows are too great to allow inspection or to be
plugged at the upstream manhole(s), then Burlingame shall coordinate with the Town
to reschedule television inspection during low flow periods such as early morning (i.e.,
between midnight and 5 a.m.).
C. In the event the section being televised has substantial flow entering the
sewer between manholes, such that inspection of the sewer is impaired, the
Burlingame shall coordinate with the owner to have the flow temporarily stopped and/or
reschedule television inspection of the particular section to a time when the flow is
reduced to permit proceeding with the television inspection.
D. When manually operated winches are used to pull the television camera
through the line, walkie-talkie radios or other suitable means of communication shall be
set up between the two manholes of the section being inspected to ensure good
communications between members of the crew.
E. The importance of accurate distance measurements is emphasized. The
accuracy of the remote reading footage counter shall be checked periodically by use of
a walking meter, roll -a -tape, or other suitable device. The accuracy shall be
satisfactory to the Town representative.
F. Should any DVD or section thereof prove to be unsatisfactory to the Town
representative, the Town may request part or all of that DVD be televised again.
SS-15.DOCUMENTATION The following listed documentation shall be provided and
the cost for such shall be included in the Burlingame's unit price for television
inspection. No additional compensation shall be made.
A. Television Inspection Reports (Logs): The Burlingame shall keep
electronic location records that clearly show the location, in relation to the reference
manholes, of each defect observed during inspection. A CD copy of such records will
be supplied to the Town representative. Pipe defects, roots, grease buildup, infiltration,
cracked laterals, and other miscellaneous abnormalities shall be located by footage
and noted in the report. If possible, laterals should also be referenced by address (i.e.,
by person above ground following with radio and roll -a -tape). Burlingame will use the
same code/defect description scheme that is in use for the City of Burlingame.
B. Each report, on each section of line televised, will have a summary and
evaluation as to the general condition of that section. Reports and DVD's shall be
turned in at least quarterly.
5
C. Television inspection data will be supplied on DVD computer disks. The
supplied data will be WINCAN. This shall be submitted with the corresponding CD
copy of reports and DVD's. Data entry shall include: ID Number, Address Number,
MH# From, MH# To, Page #, TV Date, Pipe size, TV Footage, DVD#, Code, Rating of
pipe condition and Event Photographs. Each photographic image shall be saved in a
JPEG file format and named with the footage of the event followed by the event (for
example, defect BJCM at 107.9' would be named MH#B3-21001-107.9bjcm.jpg). The
files shall be stored within a file folder named for the Upstream Manhole Number.
D. An Index must be provided and alpha -numerically sorted in the following
order: (1) Street name, and (2) upstream manhole number and (3) DVD number.
In addition, individual DVD indexes are required for each DVD, to be
located at the beginning of the log reports from each DVD. Individual DVD indexes are
to be listed in the same order as televised.
E. DVD Recordings: Burlingame shall furnish color DVD
recordings. DVD's shall be labeled and individually numbered, beginning with number
"FY 2006-07 #001". Labels shall be typewritten or computer generated and include
"TOH CCTV Project", date of DVD submittal, and DVD number. An example of the
correct label format follows:
TOH CCTV Project, FY 2006-2007
SS, Submitted 3/26/2007
DVD 01
F. The first DVD submitted shall be inspected and subject to approval by the
Town's representative. When approved this will become the standard for subsequent
DVDs. The purpose of DVD recording shall be to supply a visual and audio record of
problem areas of the lines that may be replaced. Title to the DVD's shall transfer to the
Town. Each DVD shall include the following information:
1. DATA VIEW VISIBLE ON DVD PRIOR TO INSPECTION:
• Street Name
• U/S and D/S MH number
• Anticipated distance of reach
• Size of line
• Type of pipe (if known)
