Contractor Responsibilities:

For milling, pavement striping obliteration, bridge work, and culvert railing work.

• An approved contractor shall develop and implement a Lead-Based Paint Removal and Abatement Plan for the removal of the lead-based paint, Toxicity Characteristic Leaching Procedure testing of the generated waste stream, and proper disposal of the waste stream derived from the removal of the pavement striping, paint on culvert railing, and existing bridge structure within the project limits. Lead discovered on existing project facilities is outlined in the attached test report. The contractor shall select a lead abatement contractor that meets the qualification requirements specified in the special provisions and as approved by the Engineer. The contractor shall follow all applicable federal, state, and local codes and regulations, including Arizona Department of Transportation Standard Specifications for Road and Bridge Construction (2008 Edition), related to the treatment and handling of lead-based paint.

• The contractor shall submit a Lead-Based Paint Removal and Abatement Plan for the removal of the pavement striping, existing bridge demolition, culvert railing within the project limits to the Engineer and the Arizona Department of Transportation Environmental Planning hazardous materials coordinator (602.920.3882 or 602.712.7767) for review and approval at least 10 (ten) working days prior to milling, pavement marking obliteration, bridge demolition work, or culvert railing work.

• No milling, pavement marking obliteration, bridge demolition work, or culvert railing work shall occur until the Lead-Based Paint Removal and Abatement Plan is approved by the Arizona Department of Transportation Environmental Planning hazardous materials coordinator and implemented.

• Visible fugitive dust emissions from paint removal shall be controlled through wet or dry (e.g., vacuum) means during the removal process. If the liquid waste stream generated by a water-blasting obliteration method passes the Toxicity Characteristic Leaching Process analysis, it may be used as a dust palliative or for compaction on the project. If the water is not used on the project, it shall be properly disposed of in accordance with all applicable federal, state, and local regulations.

• Paint containing lead was found in the pavement striping, existing bridge superstructure, and bridge rails;

therefore, the contractor shall notify its employees prior to any disturbance where lead is present in the paint below the 0.5 percent US Department of Housing and Urban Development/US Environmental Protection Agency action levels but above the US Department of Labor Occupational Safety and Health Administration detection level. As part of the notification, the contractor shall make the US Department of Labor Occupational Safety and Health Administration publication number 3142-12R 2004 Lead in Construction (http://www.osha.gov/Publications/ osha3142.pdf) available to workers.

http://www.blm.gov/wo/st/en/prog/more/veg_eis.html

• For milling activities, the roadway surface preceding the milling machine shall be kept sufficiently wet so as to prevent the generation of any visible fugitive dust particles but not so wet as to cause excess runoff from the roadway surface onto the roadway shoulder.

• The contractor shall complete a National Emission Standards for Hazardous Air Pollutants notification for work associated with bridge demolition and submit it to the Engineer for review.

• After Engineer approval, the notification shall be submitted to the Arizona Department of Transportation Environmental Planning hazardous materials coordinator (602.920.3882 or 602.712.7767) for a 5 (five)-working-day review and approval. Upon approval by the Arizona Department of Transportation Environmental Planning hazardous materials coordinator, the contractor shall file the notification with the Pima County Department of Environmental Quality at least 10 (ten) working days prior to demolition associated with the bridge.

• The contractor cannot start work associated with demolition of the bridge until 10 (ten) working days have passed since the submittal of the National Emission Standards for Hazardous Air Pollutants notification to the regulatory agency.

• If suspected hazardous materials are encountered during construction, work shall cease at that location and the Engineer shall be notified immediately to make arrangements for proper treatment or disposal of those materials.

• If vegetation clearing will occur during the migratory bird breeding season (March 1 to August 31), the contractor shall avoid any active bird nests. If active nests cannot be avoided, the contractor shall notify the Engineer to evaluate the situation. During the nonbreeding season (September 1 to February 28), vegetation removal is not subject to this restriction.

• To prevent the introduction of invasive species seeds, the contractor shall inspect all earthmoving and hauling equipment at the storage facility. All vehicles and equipment shall be washed and free of all attached plant/vegetation and soil/mud debris prior to entering the construction site.

• To prevent invasive species seeds from leaving the site, the contractor shall inspect all construction equipment and remove all attached plant/vegetation and soil/mud debris prior to leaving the construction site.

• If previously unidentified cultural resources are encountered during activity related to the construction of the project, the contractor shall stop work immediately at that location and shall take all reasonable steps to secure the preservation of those resources. The Engineer will immediately make arrangements for the proper treatment of those resources.

• The contractor shall notify owners of adjacent properties regarding construction timing and driveway restrictions a minimum of 14 (fourteen) calendar days prior to construction.

• The contractor shall post signs at bus stop locations within the project limits a minimum of 14 (fourteen) calendar days prior to construction to inform transit riders of the temporary relocations of the bus stops.

• The contractor shall not store equipment, supplies, materials, or debris on the sidewalks or bike paths.

Permits Before undertaking work at any location covered by this project, the Contractor shall obtain all applicable permits, including but not limited to: street closure permits and permits for excavation/construction in the public rights-of-way, from the City of Tucson and ADOT, as needed.

The contractor shall obtain all necessary permits from UPRR related to any relevant work impacting their property or right of way. Contractor shall follow all UPRR requirements for relevant work impacting their property or right of way.

The Contractor shall raise or lower to the new pavement surface, all sanitary sewers manholes in accordance with PCRWRD Standards.

Sanitary Sewer:

The frame and cover of every existing public sanitary sewer manhole and cleanout that will remain in service shall be adjusted to match the new finished grade. Reconstruction of manholes per Pima County Regional Wastewater Reclamation Department Standard Specifications and Details for Construction 2012, RWRD-211, -212, -304, or -305 (as applicable) may be necessary when adjusting manhole rims. PCRWRD also may require that the manhole frame and cover be replaced if the age, condition, or type of the existing frame and cover warrants such replacement.

Manholes and cleanouts that are located in areas subject to stormwater runoff or pedestrian traffic shall have waterproof covers (RWRD-213, -214, -215, -216, -217 or -218). If the manhole is in an unpaved area, a protective concrete collar shall be placed around the manhole as set forth in RWRD-212. Per RWRD-306, the Contractor is required to cover the bench during the adjustment process in order to prevent debris from entering the sewage flow.

The cover must be in place prior to removing the rim and cover. The Contractor shall contact Field Operations 2 weeks prior to installing any covers. If the Contractor must enter a manhole to install or remove the bench cover, a no-cost Manhole Entry Permit must be obtained from PCRWRD Mapping & Records (5th Floor, 201 N. Stone) prior to making the entry. Contact PCRWRD Field Engineering (724-2651) to arrange an inspection if there are any questions concerning adjustments to existing manholes.

When reconstruction of an existing brick manhole is required, remove the tapered section of existing brick. If brick or mortar of the straight (vertical) wall is deteriorated, continue removing the wall until solid material is reached.

The PCRWRD Inspector shall inspect the existing brick wall prior to reconstruction in order to verify that the condition is satisfactory. The Contractor shall use standard precast sections to rebuild the manhole to grade.

Where sewers that are to be abandoned are connected to in-service manholes that will remain in service, the Contractor shall plug the sewer at the manhole and rebench the manhole to accommodate changes in flow direction.

Manholes that are to be abandoned shall be demolished to at least three (3) feet below finished grade. The rings and covers shall be salvaged and delivered to the storage yard located adjacent to the Outlying Facilities office on the I-10 eastbound frontage road south of the Ina Road Water Pollution Control Facility. Contact the Field Operations Division (326-4333) to arrange for delivery of salvaged items. Debris that is generated by the removal of existing sewer shall be taken from the site by the Contractor and disposed of appropriately. Disturbed areas shall be backfilled compacted to 95% of maximum density.

Where new water mains violate the vertical separation requirements between sanitary sewer lines and potable water lines, the sanitary sewer shall be replaced with ductile iron pipe for no less than a distance of six (6) feet on each side of the waterline-sewer line intersection. This requirement shall apply to House Connection Service’s as well as sanitary sewer mains.

When trenching or excavating within six (6) feet of an existing sanitary sewer manhole, the Contractor shall adequately protect the manhole with shoring or other methods approved by PCRWRD

Drainage:

The Contractor's attention is directed to Subsection 701-3.04, Basic Maintenance and Protection of Traffic, paragraph

(C) Drainage, and Subsection 107-20, Damage by Storm, Flood or Earthquake of the Standard Specifications. The Contractor shall devote particular attention to all drainage facilities, keeping them fully operative at all times.

Conveyance of stormwater runoff shall be provided at all times, even during grading operations, to adequately drain the traveled way including the remainder of the right-of-way areas. In addition, the Contractor shall maintain existing drainage patterns and shall provide temporary conveyance for stormwater runoff to all storm drains, manholes and catch basins affected by the new construction. To this end, the Contractor shall develop a stormwater management plan, in accordance with the provisions of Subsection 107-19 Contractor's Responsibility for Work which addresses the control and disposal of stormwater throughout the duration of the construction.

Damage:

The Contractor's attention is directed to Subsection 501-3.03(A). In addition to the requirements specified in this section, the Contractor shall be solely responsible for all existing pipe, catch basins and grates that are to remain and which are deemed to have been damaged by the actions of the Contractor or the Contractor's subcontractors. Any damage so caused shall be corrected at the sole cost of the Contractor.

Regional Transportation Authority (RTA) Construction Signs:

Where applicable, the RTA has contracted with a Sign Contractor to provide and install signs on all RTA funded construction projects. Signs will indicate to the traveling public the type of project being constructed, the jurisdiction in which the project is located and that RTA funding is being utilized for the project. The Sign Contractor will work with the City representative to ensure that signs are installed a minimum of 7 days prior to construction start and will remain in place a minimum of 30 days after construction ends. The Sign Contractor will be responsible for Blue Staking for the sign installation and any required permits and will install signs in a location to be coordinated with the City representative and the Construction Contractor. Signs will be 4 ft. x 4 ft. for most projects, 4 ft. x 8 ft. for larger corridor projects and will be placed at all logical approaches to the project. The Construction Contractor will work with the City representative and the Sign Contractor to ensure that locations selected for signs are visible to the traveling public, do not violate sight distance requirements, and do not block other signs, business lines of sight, or construction access.

Coordination with Union Pacific Railroad:

Construction activities within the Union Pacific Railroad (UPRR) will require close coordination with UPPR.

Construction activities include, but are not limited to, construction of bridge piers (both temporary and permanent), box culvert and slope paving, water service modifications, and other miscellaneous items. UPRR requires their flagging personnel to be on site during any construction activity that is within 25 feet of the track both horizontally and vertically. Prior to beginning construction, the Contractor shall submit to the Engineer and UPRR a schedule defining the start date and duration for construction of each activity required within the yard. The Contractor will be responsible for coordination with UPRR to schedule the flagging personnel.

Coordination with the Arizona Department of Transportation:

Construction activities within the Arizona Department of Transportation (ADOT) right-of-way will require coordination with ADOT. Construction activities include, but are not limited to, the removal of the existing bridge, the new 22nd Street bridges, Barraza-Aviation Parkway and Ramps A, B and C reconstruction, drainage improvements, water and sewer improvements, street lighting, traffic signal modifications, signing, pavement marking, and other miscellaneous items. Prior to beginning construction, the Contractor shall submit to the Engineer and ADOT a schedule defining the start date and duration for construction of each activity required on an ADOT facility.

The Contractor shall include the timeframe for lane closures required to complete construction activities on or adjacent to Barraza-Aviation Parkway in their construction schedule and submitted to ADOT for final approval. Lane closures beyond the limits approved by ADOT will inconvenience the traveling public and will be a cost to the Agency.

It is impractical to determine the actual damages the Agency will sustain in the event Traffic Lanes are closed beyond the limits approved by ADOT. Therefore, the Contractor shall pay to the Agency, not as a penalty, but as liquidated damages, $500 per 15 minutes, or for a portion of 15 minutes, per lane, for any lane closure beyond the limits approved by ADOT. In addition to the liquidated damages, all added cost for traffic control measures, including flagging, required to maintain the lane closures beyond the allowed time limits, will be at no additional cost to the Agency. The required traffic control measures will be as determined by the Engineer.

The Engineer will determine when it is safe to reopen lanes to traffic. Assessment of liquidated damages will stop when all lanes have been safely reopened. Any liquidated damages assessed under these provisions will be in addition to those listed in the PAG Standard Specification Sections 105 and 108.

Project Limits The contractor shall perform all work within the public right-of-way, legally obtained easements and property legally acquired by the Agency.
