This policy prohibits discrimination by the City's contractors, consultants and vendors and requires them to ensure that applicants seeking employment with them and their employees are treated equally without regard to race, color, creed, religion, national origin, sex, gender identity, sexual orientation, disability, marital status, and age. It is the City's intention to assist employers, who are City contractors, vendors or consultants, in designing and implementing equal employment opportunity so that all citiaens will be afforded equal accessibility and opportunity to gain and maintain employment. PROVISIONS: All contractors, vendors, and consultants requesting to do business with the City must submit an Equal Opportunity Policy Statement before the execution of the contract. 2. All City contractors, vendors, and consultants with contracts of $25,000 or more (or less if required by another governmental agency) must abide by the requirements of the City's Contract Compliance Program. Emergency contracts may be exempt from this provision at the discretion of the City. Regardless of the value of the contract, all contractors, vendors, and consultants are subject to the City's Human Rights Ordinance, which is codified at Article 2 of the City Code. 3. Contracting departments are responsible for assuring that City contractors, vendors, and consultants are made aware of the City's Contract Compliance Program reporting responsibilities and receive the appropriate reporting forms. A notification of requirements will be included in any request for proposal and notice of bids. 4. Prior to execution of the contract, the completed and signed Assurance of Compliance (located on pages CC-2 and CC-3) or other required material must be received and approved by the City. 5. Contracting departments are responsible for answering questions about contractor, consultant and vendor compliance during the course of the contract with the City. 6. All contractors, vendors, and consultants must refrain from the use of any signs or designations which are sexist in nature, such as those which state "Men Working" or "Flagman Ahead," and instead use gender neutral signs. All contractors, vendors, and consultants must assure that their subcontractors abide by the City's Human Rights Ordinance. The City's protected classes are listed at Iowa City City Code section 2-3-1. %: L F.. . __~ _... :.~: CC-1 SECTION II -ASSURANCE OF COMPLIANCE The following sets forth the minimum requirements of a satisfactory Equal Employment Opportunity Program which will be reviewed for acceptability. PLEASE RETURN PAGES CC2 AND CC3 OF THIS SECTION TO THE CONTRACTING DEPARTMENT PRIOR TO THE EXECUTION OF THE CONTRACT. With respect to the performance of this contract, the contractor, consultant or vendor agrees as follows: (For the purposes of these minimum requirements, "contractor" shall include consultants and vendors.) a. The contractor will not discriminate against any employee or applicant for employment and will take affirmative efforts to ensure applicants and employees are treated during employment without regard to their race, color, creed, religion, national origin, sex, sexual orientation, gender identity, disability, marital status, and age. Such efforts shall include, but not be limited to the following: employment, promotion, demotion, or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. b. The contractor will, in all solicitations or advertisements for employees placed by or on behalf of the contractor, state that it is an equal opportunity employer. Note: Contracts that are federally funded are subject to Executive Order No. 11246, as amended, and the regulations (see generally 29 U.S.C. § 1608 et se .) and relevant orders of the U.S. Secretary of Labor. The Secretary of Labor, and not the City, enforces said regulations and orders. 3. Provide a copy of your written Equal Employment Opportunity policy statement. Where is this statement posted? 4. What is the name, telephone number and address of your business' Equal Employment Opportunity Officer? (Please print) Phone number Address The undersigned agrees to display, in conspicuous places at the work site, all posters required by federal and state law for the duration of the contract.

The above responses to questions 1 through 6, are true and correctly reflect our Equal Employment Opportunity policies.

Document the policy and post it in a conspicuous place so that it is known to all your employees. Furthermore, disseminate the policy to all potential sources of employees and to your subcontractors asking their cooperation. The policy statement should recognize and accept your responsibility to provide equal employment. opportunity in all your employment practices. In regard to dissemination of this policy,. this can be done, for example, through the use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web page postings, employee handbooks, and advertising. EQUAL EMPLOYMENT OPPORTUNITY OFFICER Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of administering and promoting your company's Equal Employment Opportunity program. This person should have a position in your organization which emphasizes the importance of the program. INSTRUCT STAFF Your staff should be aware of and be required to abide by your Equal Employment Opportunity program. All employees authorized to hire, supervise, promote, or discharge employees or are involved in such actions should be trained and required to comply with your policy and the current equal employment opportunity laws. RECRUITMENT (a) Let potential employees know you are an equal opportunity employer. This can be done by identifying yourself on all recruitment advertising as "an equal opportunity employer". (b) Use recruitment sources that are likely to yield diverse applicant pools. Word-of--mouth recruitment will only perpetuate the current composition of your workforce. Send recruitment sources a letter annually which reaffirms your commitment to equal employment opportunity and requests their assistance in helping you reach diverse applicant pools. (c) Analyze and review your company's recruitment procedures to identify and eliminate discriminatory barriers. (d) Select and train persons involved in the employment process to use objective standards and to support equal employment opportunity goals. (e) Review periodically job descriptions to make sure they accurately reflect major job functions. Review education and experience requirements to make sure they accurately reflect the requirements for successful job performance. (f) Review the job application to insure that only job related questions are asked. Ask yourself "Is this information necessary to judge an applicant's ability to perform the job applied for?" Only use job-related tests which do not adversely affect any particular group of people. (g) Monitor interviews carefully. Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws. Biased and subjective judgments in personal interviews can be a major source of discrimination. (h) Improve hiring and. selection procedures and use non-biased promotion, transfer and training policies to increase and/or improve the diversity of your workforce representation. Companies must make sure procedures for selecting candidates for promotion, transfer and training are based upon a fair assessment of an employee's ability and work record. Furthermore, all. companies should post and otherwise publicize all job promotional opportunities and encourage all qualified employees to bid on them. r I..._ t_ _ - ,-_ , _. ~K.a ".

Concrete sidewalk pavements, and base courses and bituminous surfaces shall be replaced with new materials and the cost shall be paid per the areas and bid: items shown in the plans. 3.05 -BORED CONDUIT A. It is intended that all conduit be placed without disturbing the existing pavement, and the term "bored" is used. "Bored" conduit shall be placed by directional drilling or any other means necessary to place the conduit and control the conduit depth and alignment without cutting or removing pavement. B. Removal of pavement will require prior approval of the ENGINEER. Replacement of removed pavement will be done to the same thickness and material as the existing pavement. For PCC patches, joints shall be drilled and dowelled according to IDOT Standard Plan RH- 50 at 18" centers. PCC paving shall be Type M Mix with accelerant. HMA shall be'/4" base and 3/8" surface mix. HMA surface shall be a minimum of 2" thick. No payment will'be made for removal and replacement of pavement. C. Plan quantities for bored conduit are measured from center of handhole to center of handhole. Measurements are plan distance. No additional payment will be made for extra length of conduit to account for vertical changes in the project topography. Likewise, all extra bends, alignment changes to avoid existing utilities, or miscellaneous lengths of conduit to complete the run from handhole to handhole, or handhole to controller cabinet are incidental. D. The maximum conduit depth at handholes for all conduits, including pushed conduit, is as shown on the plans. E. Risers up power poles are included in the quantity for bored conduit. All risers shall be 2" galvanized steel. The riser shall be connected to the HDPE conduit via a coupling 16571-8 specifically designed for connecting galvanized steel to HDPE. Risers shall be grounded with their own separate grounding rod and grounding wire per these specifications. 3.06 -ELECTRICAL A. Cables shall be pulled through conduit by means of a cable grip designed to provide a firm hold upon the exterior covering of the cable or cables, with a minimum of dragging on the .ground or pavement. This shall be accomplished by means of reels mounted on jacks or other suitable devices. Frame-mounted pulleys, or other suitable devices shall be used for pulling the cable out of conduits into handholes. Only vegetable lubricants may be used to facilitate the pulling of cable. Contractor shall leave a pull string in each conduit. B. Each cable shall be identified with an identification tie in the handholes, and at any splice or junction location. Identification ties shall be of an opaque nylon material arranged to include a marker board, non-releasing holding device, and cable fastening tail. The marking board shall be not less than 3/8 inch wide by 3/4 inch long, and 25 mils thick, roughened on one side to hold permanent black nylon marking ink from a pen. Identification shall be permanent and water-proof. Once installed, the tie shall not be removable except by cutting it loose from the cable. C. Cable slack shall be as follows: fifty feet (50') in handholes fifty feet(15') in the terminal compartment of the controller base D. A tracer wire shall be installed in all conduits with fiber optic cables. The tracer wire shall be identified in the controller cabinet and handholes by means of identification tags. The tracer wire shall be spliced in the handholes to form a continuous network. 3.07 -GROUND RODS A. Ground wires shall be connected to ground rods with one-piece nonferrous clamps which employ set-screws as tightening devices. Connections to ground rods need not be taped. B. Each riser shall be firmly connected to the ground rod provided, by means of the grounding terminal specified in these special provisions. 3.08 -FIBER OPTIC CABLE A. Cable Installed in Ducts and Conduits A suitable cable feeder guide shall be used between the cable reel and the face of the duct and conduit to protect the cable and guide it into the duct off the reel. It shall be carefully inspected for jacket defects. If defects are noticed, the pulling operation shall be stopped immediately and the ENGINEER notified. Precautions shall be taken during installation to prevent the cable from being "kinked" or "crushed". A pulling eye shall be attached to the cable and used to pull the cable through the duct and conduit system. A pulling swivel shall be used to eliminate twisting of the cable. As the cable is played off the reel into the cable feeder guide, it shall be sufficiently lubricated with a type of lubricant recommended by the cable manufacturer. Dynamometers or breakaway pulling string shall be used to ensure that the pulling line tension does not exceed the installation tension value specified by the cable manufacturer. The mechanical stress placed on a cable during installation shall not be such that the cable is twisted or stretched. The pulling of cable shall be hand assisted at each controller cabinet. The cable shall not be crushed, kinked, or forced around a sharp corner. Lubricant shall be used and it shall be of water-based type and approved by the cable manufacturer. Sufficient slack shall be left at each end of the cable to allow proper cable 16571-9 termination, MINIMUM OF 50 FEET. This slack shall be in addition to installation slack as hereinafter specified. Additional slack cable shall be left in each controller cabinet, junction box, at the top of each conduit riser, and at each wood support pole. Storage of minimum slack cable in controller cabinets and additional slack at pull boxes shall be coiled. The slack coils shall be bound at a minimum of 3 points around the coil perimeter and supported in their static storage positions. The binding material and installation shall not bind or kink the. cable. Storage of additional slack cable adjacent to conduit risers and support poles shall be visibly marked/tagged as "CAUTION -FIBER OPTIC CABLE". Maximum length of cable pulling tensions shall not exceed the cable manufacturer's recommendations. Along with the fiber optic cable, one (1) # I O AWG THHN, 600 volt single conductor cable (identifier conductor), orange in color, shall be pulled with ten feet (10') slack in each pull box, except where rigid metallic conduit or other metallic conductors are installed. B. Minimum Bend Radius For static storage, the cable shall not be bent at any location to less than ten times the diameter of the cable outside diameter or as recommended by the manufacturer. During installation, the cable shall not be bent at any location to less than twenty times the diameter of the cable outside diameter or as recommended by the manufacturer. 3.09 -EQUIPMENT TESTING A. Each section of the fiber optic cable shall be tested for continuity and attenuation as a minimum. If the attenuation is found not to be within the acceptable nominal values, the CONTRACTOR shall use an optical time domain reflectometer (OTDR) to locate points of localized loss caused by bends or kinks. If this is not successful the CONTRACTOR shall replace the damaged section of cable with no additional payment. Splices will not be allowed to repair the damaged section. After all fiber cable is installed, the Contractor shall test continuous cable segments using the OTDR. Multimode fiber may be tested using 1300 nm and single mode may be tested at 1310 nm. The results of the OTDR test shall be provided on an electronic media (disk) and paper printout. The OTDR wave, pictorial diagram of dB loss over the length of fiber tested, shall be provided along with the measured data values. The printout shall contain the manufacturer's fiber optic Index of Refraction to the third decimal point for the fiber provided. The CONTRACTOR shall provide the ENGINEER with a written report showing all the values measured compared to the calculated values for length and coupler/connector losses at the completion of these tests. Data documentation shall include for each test between cable ends, the length of fiber as measured by OTDR, frequency used in test on OTDR by each fiber type, dB loss rating by manufacture from spool documentation, index of refraction by type of fiber in section, and the dB loss of each section as measured in the final test for each fiber. The Contractor shall test 4 strands per buffer tube minimum after installation. B. Fiber Optic Cable Attenuation The end-to-end attenuation shall be measured for each link after installation. The launch cable shall be connected to the light source and the receive cable to the power meter. -The two reference cables shall then be connected via a termination hub. 16571-10 The system link to be tested shall then be inserted between the launch and receive cables using 2 termination hubs (couplers). The direction of the test shall be recorded in the documentation to verify the quality of the termination. C. Continuity tests shall be used to determine whether a test or system jumper does or does not pass light. A continuity test shall also be used to assure the fibers have not been crossed over in the jumper and that the transmit fiber goes to the receiver fiber. To perform continuity test, ahigh-intensity flashlight shall be aimed into the connector at one end, while an observer watches for a flicker of light at the other end. A 650 nm red NFL light source shall be provided to the end at the completion of the continuity testing. This device shall be made available during testing of continuity to the ENGINEER to assist in verifying fault locations and connector bleeding. D. It is recommended an Optical Time Domain Reflectometer (OTDR) shall be used to evaluate the quality and length of cable reels prior to their use on the project. The fiber loss in dB/km and the length of each reel shall be recorded in the documentation. The maximum attenuation of the cable shall be as hereinbefore specified. It is recommended the Contractor test 1 strand per buffer tube on the reel and perform a visual inspection of the cable on the reel prior to installation to check for damage due to shipping, handling, etc. Do not install damaged cable. If the Contractor elects to test the cable on the reel a hard copy of OTDR signature traces, electronically and in printed form, for all reels shall be made and provided in the documentation as specified. E. The result of all testing shall be recorded along with date of test, name of person performing test, brand name, model number, serial number of equipment used during test, and any other pertinent information and data. F. Ground testing shall conform to Section 2523.21 of the Iowa DOT Standard Specifications for Highway and Bridge Construction. 3.10 -CLEAN-UP A.
