TECHNICAL SPECIFICATIONS

Stormwater Pipe CCTV Inspection

1. GENERAL

1.1 Purpose

The purpose of this contract is to provide all labor, equipment, materials, and incidentals necessary to perform Stormwater Pipe CCTV Inspections. All stormwater pipes, culverts, and associated structures within the City of Tampa's jurisdiction are subject to CCTV inspection as needed or as part of a scheduled maintenance program. The overall quality of the inspection video and data is subject to the approval of City of Tampa staff.

1.2 Scope of Work

This specification covers the minimum requirements for closed-circuit television (CCTV) inspection of stormwater conveyance systems within the City of Tampa. It applies to public infrastructure and should be adapted to local municipal standards as needed.

To visually assess the structural and operational condition of stormwater pipes, document defects, verify alignment, and support maintenance, rehabilitation, or replacement planning.

2. BIDDER REQUIREMENTS AND SUBMITTALS

Bidders shall submit with their bid evidence in writing that they maintain a permanent place or places of business and have adequate equipment, finances, and personnel to provide the specified services. This evidence shall include, but not be limited to: a list of current contracts, their value, and a contact person with each firm; at least 3 references who can verify work of a similar nature done by your firm in the last 3 years; a list of owned and/or leased equipment available for use on this award; a list of key personnel and a brief summary of their qualifications. Note also that when entering into an underground Stormwater box the individual involved in entering the box, must have been trained in OSHA “permit required confined space”.

Inspector Qualifications: - All CCTV inspection personnel must be PACP-certified - Equipment operators must be trained and experienced in stormwater systems Provide a complete list of tools and equipment owned or leased. It is strongly recommended that the Awardee possess (own or rent) and use the following equipment, in the performance of this Award:

Equipment Requirements

2.1 CCTV Camera: - High-resolution, color pan-and-tilt camera - Minimum 360° pan and 270° tilt capability - Self-leveling and focus-adjustable - Integrated LED or halogen lighting with adjustable intensity - Minimum resolution: 480 TVL (TV lines)

2.2 Crawler: - Motorized, remotely operated crawler - Variable-speed control - Capable of navigating pipe sizes from 6” to 96” - Interchangeable wheels or tracks for different pipe diameters and materials

2.3 Cable and Reel: - Sufficient length to inspect continuous runs up to 1,000 ft - Footage counter accurate to ±1%

2.4 Recording System: - Digital video capture system in MPEG-4, AVI, or H.264 format - Overlay of date, time, segment ID, and camera direction on video.

Pipe Cleaning Equipment are only required when the pipes are blocked with debris and the CCTV Inspections cannot be performed. Subcontracting this portion of the work will be allowed.

2.5 Vacuum trucks (Vactor trucks): Powerfully suction debris, sediment, and liquids from stormwater pipes and catch basins. They are essential for both dry and wet cleaning methods, capable of removing solids and semi-solids effectively.

2.6 High-velocity jetters: Use pressurized water (up to 2000+ PSI) to scour pipe walls, loosen and flush out debris such as grease, sediment, and roots. Jetters come with a variety of nozzles to target different blockages and pipe sizes.

9. Inspection Procedures – CCTV Inspection of Stormwater Pipes

· Before the inspection, the access point and the pipe's entirety should be visually inspected to identify any potential obstructions.

· A safety perimeter with appropriate barriers and cones must be established in the surrounding area before gaining access to the pipe.

· The appropriate equipment should be selected based on the pipe's size.

· The camera should be inserted through the access point (manhole, storm grate, cleanout, etc.), utilizing safety precautions like pole-mounted hooks or ropes to avoid confined space entry.

· The camera should be moved through the pipe at a uniform rate, not exceeding 30 feet per minute, stopping as needed for thorough documentation.

· In case of blockages hindering the inspection in one direction, attempts should be made to inspect from the opposite manhole. If this also fails, the obstruction needs to be removed through cleaning or, if necessary, excavation and replacement.

· The entire circumference of the pipe must be visible in the recorded video.

· Any flow control measures (e.g., removing standing water or debris) required for optimal video quality shall be paid under Pipe Clening.

· Weather conditions impacting video quality should be considered, potentially leading to delays after major rain events until the system's flow returns to normal.

10. Manhole/ Inlet Inspection.

· Visual Inspection: Conduct a thorough visual inspection of all internal surfaces using adequate lighting:

Structure: Examine the manhole or inlet walls and bottom for cracks, damage, or signs of erosion.

Connections: Inspect all pipe connections to ensure they are secure and in good condition.

Seals/Gaskets: Check the integrity of seals, gaskets, and embedment’s for proper placement and condition.

Debris/Sediment: Assess the level and type of debris and sediment accumulation. Note if it’s blocking the inlet, outlet, or filling the sump.

· Camera Inspection: Utilize CCTV or other remote inspection cameras for hard-to-reach areas or detailed internal views.

· Information to Record: Include details such as:

Manhole/Inlet ID and location Date and inspector names Materials and condition of components (frame, cover, walls, etc.)

Evidence of infiltration or leaks Type and depth of debris/sediment Photos

· Report Findings: Summarize the inspection results, noting any defects or issues that require further action (e.g., cleaning, repair, replacement).

11. Pipe Cleaning - Only required when the CCTV Inspections cannot be performed.

· 24-Inch and Under: Contractor shall clean pipes using high-velocity jet/vacuum methods. Pipes shall be flushed thoroughly and sediment and debris fully removed.

· Over 24-Inch: Contractor shall clean large-diameter pipes using high-velocity/vacuum methods or mechanical cleaning tools, depending on site conditions. All material must be vacuumed or mechanically extracted and not left in the system.

Jetting without recovery is strictly prohibited. All debris must be removed and disposed of in accordance with Section 9.8. No additional payment shall be made for Debris Removal.

12. Data Recording and Reporting

· Coding Standards: - Follow NASSCO PACP (Pipeline Assessment Certification Program) for all defect classifications - Optional: use MACP/LACP for manholes and laterals

· Deliverables: - Digital video files for each segment - PDF or Excel-based inspection logs - JPEG or PNG image files of defects - Optional: GIS-compatible shapefiles or CAD overlays

· Inspection Log Contents: - Project name and location - Date/time of inspection - Pipe diameter, material, shape, and length - Segment ID and direction of inspection - List of defects with PACP codes, severity ratings, and remarks

· Still pictures in color JPEG format should be taken of all significant defects, including location, clock position, time, and defect code.

· A final report must be prepared and submitted to the City of Tampa staff within 14 calendar days of the inspection.

· Data Reporting shall be submitted per work order.

13. PAYMENT
