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 citizens 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. 7. 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. _r c, c, 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.

P1 i 1 J cJ 2. 3. 9 SECTION III - SUGGESTED STEPS TO ASSURE EQUAL EMPLOYMENT OPPORTUNITIES COMPANY POLICY Determine your company's policy regarding equal employment opportunities. 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 intq'rviews can be a major source of discrimination. (h) IMprove .hiring and selection procedures and use non - biased promotion, transfer and training fr policies- to, increase and/or improve the diversity of your workforce representation. Companies must rij'alFe sure procedures for selecting candidates for promotion, transfer and training are based- -:uton a fair assessment of an employee's ability and work record. Furthermore, all comp'anfes should post and otherwise publicize all job promotional opportunities and encourage l gda7it6d employees to bid on them. o ` N CC -4 I � � A ) / J P City of Attached for your information is a copy of Section 2 — 3 — 1 of the Iowa City Code of Ordinances which prohibits certain discriminatory practices in employment. Please note that the protected characteristics include some not mandated for protection by Federal or State law.

Page I I of20 The overall rolling procedure and compactive effort shall produce a surface free of ridges, marks, or bumps and shall be subject to approval of the Engineer. There are two classes of compaction, Class I and Class II. Class I compaction is intended for use on Secondary highways. Class II compaction is intended for resurfacing paved shoulders, temporary crossovers, runarounds, and for other situations where Class I is riot specified. For Class I compaction, the roadway density (percent of laboratory density) will be based on the density obtained from the Quality Control Program for that day's mixture. 1. Class I Compaction. a. Class IA Compaction. Compaction shall be a minimum of 90% of laboratory density. The average air void level of the roadway density specimens shall not exceed 8.0 %. b. Class IB Compaction.Class IB compaction shall be used when Class IA compaction is not specified. Compaction shall be to a minimum of 95% of laboratory density. The average air void level of the roadway density specimens shall not exceed 8.0 %. c. Class IC Compaction.Class IC compaction shall be used for traffic lanes of Secondary highways, HMA base widening, shoulder resurfacing, and any other HMA course when Class IA and IB are not specified. Compaction shall be a minimum of 94% of laboratory density. The average air void level of the roadway density specimens shall riot exceed 8.0 %. d. Rolling Patterns for Class IA and IB Compaction. For Class IA compaction at the start of intermediate course placement and for Class IA and Class IB compaction prior to the start of surface course placement, the Contractor shall construct atest strip for the purpose of evaluating properties of the HMA mixtures and for identifying an effective rolling pattern. For multiple lifts using the same mix requiring Class IA compaction, when the thickness of the second lift varies from the first lift by 1 112 inches (40 nun) or more, a test strip for the second lift shall be performed. When the contract documents specify both intermediate and surface courses, a surface course test strip shall be placed in lieu of intermediate mix in a section of intermediate course prior to actual surface course placement. This will be paid for at the contract unit price for the surface mix. The test tri shall be applied to each mixture which has a Ian quantity of at least 1500 tons 1500 �-; c`� P PP P q Y c - tvIg). N The quantity of HMA mixture subject to Class IA compaction, produced and placed for test strip production, will be limited to 500 tons (500 Mg) for lift thicknesses of 2 inches (50 mm) or less, and 750 tons (750 Mg) for lift thicknesses greater than 2 inches (50 mm). After test strip placement, further mixing and laydown operations will be suspended until the laboratory test results of the plant produced mixture and core densities are available. Only one test strip will be allowed for each mixture. Al the direction of the Engineer, additional test strips may be required if a successful rolling pattern was not established. Procedures and documentation to be followed during construction of the test strip shall allow the Engineer and the Contractor to verify mixture design and effectiveness of compaction procedures. The number of density core samples obtained for the test strip will be increased by one and the low core result will not be used in the Quality Index (0.I.) density fornuda for payment for the test strip quantity. 2. Class II Compaction. For all rollers, the initial contact with the hot mixture shall be made by the power driven wheels or roll. 1, t.-- I4 ........ ;- ,,,..,I"r,..... /0. -1 /.,,,.6:..,.,.! /1,.f 10o,;' @Q'.•,n.t „nh:Ce -n 101-1 1, t...

Except on longitudinal joints and super - elevated curves, rolling with the initial roller shall begin at the outer edges of the pavement, and each successive pass shall progress inward toward the center line. Each reverse trip shall lap all but 4 to 6 inches (100 mm to 150 mm) of the previous track. When reversing direction, the initial roller shall stop at an angle with the longitudinal direction. Following the initial rolling, the layer shall be given an intermediate rolling with a pneumatic tired roller, and before the temperature falls below 225 °F (110 °C). The intermediate roller shall cover the entire area not less than six times. A finish, steel tired roller shall be used to smooth out all marks and roughness in the surface. N O Mechanical tampers shall be used for areas inaccessible to the rollers. �n 3. Joints. Longitudinal joints for courses on resurfacing projects shall be constructed directly_)56ve the i longitudinal joint in the existing pavement. The offset distance between longitudinal joints in 'r succeeding courses of full depth HMA paving shall be not more than 3 inches (75 min): Transverse' construction joints in succeeding courses shall be separated by not less than 6 feet (1.6, m). The spreading of hot mixtures along longitudinal joints shall be adjusted to secure complete join( &losure and full compression of the mixture with a smooth surface and joint after compaction. At trapsverse joints, the cold mixture of the layer shall be sawed to a straight line at right angles to the center line so that a full thickness, a true surface, and a vertical edge will be provided. The Contractor shall provide a 10 foot (3 m) straightedge for checking transverse joints for smoothness. Variations in the surface at transverse joints, as indicated by the straightedge, shall be corrected by hand methods before compaction. Suitable paper or burlap should be used under the taper at end -of -day's run transverse joints to prevent adhesion. Sand, dirt, or wood shall not be used for this purpose. Use of wood or metal headers to form the edge of the joint during rolling of the fresh mixture will not be permitted. When temporary transverse construction joints will be open to traffic for periods greater than 4 weeks, the Contractor may reduce the amount of top size aggregate in the transition taper. E. Miscellaneous Operations. 1. Leveling and Strengthening Courses. The contract documents will show the thickness of the courses to be placed. Strengthening and leveling courses will be placed as indicated in the contract documents. These courses shall be of the same mixture specified for the base or intermediate course. When the width of any strengthening or leveling layer is 8 feet (2.4 m) or more, the layer shall be spread by a finishing machine. Leveling courses shall be compacted using Class II compaction procedures with a pneumatic roller. 2. Wedge Courses. Wedge courses used to secure desired super - elevation of curves shall be constructed of the base or intermediate mixture, and insofar as possible, shall be spread by a finishing machine. In placing wedge course, the maxinuim thickness of individual layers, when compacted, shall not exceed 3 inches (75 mm), and care shall be used to avoid crushing the coarse aggregate. Wedge courses shall be placed to the full width of pavement. 3. Fixtures in the Pavement Surface.

The Contractor shall produce a mixture of uniform composition conforming to the JMF. If, during production, the Contractor determines from quality control testing that adjustments are necessary to the JMF to achieve the specified properties, adjustments to the JMF target gradation and asphalt binder content values may be made. Adjustments to the JMF aggregate proportions and asphalt binder content shall be made as a result of the interactive process between the Contractor and the Engineer. The Contractor's adjustment recommendations shall prevail, provided all specifications and established mix design criteria are being met for plant production. The voids in the mineral aggregate (VMA) and estimated film thickness shall be measured for specification compliance every day of HMA production. Quality control charts shall be available and kept current showing both individual test results and moving average values. Moving averages shall be Based on four consecutive test results. Control charts shall include a target value and specification tolerances. As a minimum, the following values shall be plotted on Iowa DOT Materials approved control charts as indicated below: C' J - Laboratory density (each point being an average of two specimens). e Laboratory air voids (plotted to nearest 0.1 %) R �9 Asphalt binder content (plotted to nearest 0.1 %) - _ E3P-#d feed gradation (No. 4, No. 8, No. 30, and No. 200 (4.75 min, 2.36 mm, 600 pm, 75 pm sieves) Maximum specific gravity (Rice) (Materials I.M. 350)_ Laboratory voids for individual tests shall be calculated according to Materials I.M. 510, using the individual density and individual maximum specific gravity determined for each sample. The moving average of laboratory voids shall be the average of the last four individual laboratory voids. The Contractor shall monitor the test results and to make mix adjustments, when appropriate, to keep the mixture near the target values- The Contractor shall notify the Engineer whenever the process approaches a specification tolerance limit. One moving average point for laboratory air voids outside the specification tolerance limit shall be cause to cease operations. The Contractor shall assume the responsibility to cease operations, including not incorporating produced material which has not been placed The process shall not be started again until the Contractor notifies the Engineer of the corrective action proposed. C. Construction. 1. Density. Density samples shall be taken from the compacted mixture and tested not later than the next working clay following placement and compaction. 1.u.,.0 .........:........1..e ..,...L...I L.,... 1.:..... nini.r 1_1. -- .-: e.vnn SS- 01014 1101 \41\ ASPHALT (GYRATORY MIX DESIGN FOR LOCAL SYSTI. Page 16 of 20 A lot shall be considered as one layer of one mixture placed during a day's operation The Engineer may approve classifying multiple layers of construction placed during a single clay as a lot provided only one mixture was used. When the clay's operation is 2500 square yards (2500 (112) or less, or the day's operation Is 500 tons (500 Nlg) or less, or when the mixture is being placed in irregular areas, or for wedge, leveling, or strengthening courses, the Engineer may waive sampling for density provided compaction has been thorough and effective. Seven density samples will be taken for each lot. The length laid in each lot shall be divided into seven approximately equal sections and one sample will be obtained at a random location in each section. If a sample is damaged or measures less than 70% or more than 150% of the intended thickness, an alternate sampling location will be determined and used. Samples shall not be taken less than I foot (300 rum) from the edge of a given pass of the placing equipment or from run -.outs or areas adjacent to day's work joints or structures. The quality index for density of each lot shall he determined by the following formula: , v, -rage G c JMYT `'Z)ellslt' t x (�aVtid�C G irl ( I DHiNR' — I O a =15 where Gmb = bulk Specific Gravity of the mixture When the quality index falls below 0.00, the Engineer may declare the lot or parts-0j+t(i e Iqt =f G defective. If one of the density test values from a lot is an outlier, identified in accordance with -the proEftl e described in Materials I.M. 508, the outlier value shall not be used to determine the quality index. The quality index shall be determined using the remaining density test values. If only one laboratory density value is obtained that day, combine that value with the next day's test results to evaluate both clays' production. If two or more laboratory density values are obtained that day, then the average of those tests alone shall be used. If a significant mix change has been made, only the appropriate laboratory density values should be used with the corresponding density cores. 2. Thickness. The thickness of the completed course will be measured to the nearest 1/8 inch (3 nun), exclusive of seal coat, by measurement of cores All areas of uniform and similar thickness and width for the project will be divided into lots. The frequency specified for taking density samples from the surface lift will be used when measuring for completed thickness. However, samples that may not be tested for density because they are less than 70% of the intended thickness shall be used for thickness, and in these particular instances, the additional samples of sufficient thickness that are used for density tests shall not be measured for thickness. Thickness samples will be taken full depth of the completed course and after measurement, the density samples for the top layer shall be removed by the Contractor from the core. If any of the measurements for a lot is less than the designated thickness, the quality index for thickness of that lot will be determined by the following formula: I = rr e 'Muck ,es_: - (`lluc },less - tl Iv1axitnwn ' luckness UL-,Sue.II, - P'Aum,uun Tluc}:u-,ess MF `,U£r, When the day's operation is 2500 square yards (2500 nl2) or less, or the mixture is being placed in irregular areas or next to structures, the Engineer may waive sampling for thickness provided there is reasonable assurance that the pavement conforms to the required thickness.

The Contractor shall calibrate and correlate the testing equipment with prescribed procedures. Sampling and testing shall conform with specified testing procedures as listed in the Materials I.M. and applicable Specifications. When the results from a lab are used for product acceptance, the lab shall be qualified. All samples shall be identified, stored and retained by the Contractor for the Contracting Authority until the lot is accepted. The Contracting Authority may acquire these samples for comparative, verification, or assurance testing. All samples shall be identified by a system approved by the Engineer. 1. Loose Material Requirements. All samples of asphalt binder and lack coat material, shall be identified and promptly delivered to the appropriate laboratory, as designated by the Engineer. Samples of loose HMA mixture shall be taken behind the paver, weigh at least 50 pounds (25 kg), and shall be transported to the test facility in a way to retain heat to facilitate sample splitting procedures. The tests for mixture properties shall be conducted on representative portions of the mix, split from the larger sample of mix. After splitting of the sample is completed in the Contractor's QM -A laboratory, the remainder of the sample, approximately 30 pounds (15 kg) shall be retained for laboratory testing by the laboratory designated by the Contracting Authority. When requested by the Engineer, normally once per day, an additional 50 pounds (25 kg) box sample will be required for correlation and validation testing. f - _ "Samples shall be split in accordance with Materials I.M. 357. All test results and calculations shall be recorded and documented on data sheets approved by the - Contracfing Authority. Specific test results shall be recorded on a daily summary sheet approved by I 'the; Q'driracting Authority. The Daily Quality Control Summary Sheet shall also include a description -:of qt olity control actions taken (adjustment of cold feed percentages, changes in JMF, etc.). The Conlrbstor shall FAX, or by other method approved by the Engineer, the daily quality control sunun'ary, sheet to the appropriate Iowa DOT District Materials Engineer or Engineer daily. A copy of the electronic file containing project information generated during the progress of the work shall be furnished to the Engineer at project completion. 2. Finished Pavement Requirements. The Contractor shall cut samples from any course or finished pavement for tests of density, thickness, or composition, by sawing with a power driven masonry saw or by drilling a minimum 4 inch (100 mm) nominal diameter core. The surfaces shall be restored by the Contractor the same day. The core holes shall be dried, filled with the same type of material, and the material properly compacted. Pavement core samples shall be identified and delivered to the Contractor's quality control field laboratory. The compacted HMA pavement shall be tested by Contractor's personnel who are Iowa DOT Certified in QM -A bituminous quality control. The minimum number of cores taken shall be in accordance with the following Materials I.M. 204 Appendix AN, and Materials I.M. 204 Supplemental. The core locations will be determined by the Engineer. The cores shall be prepared and tested in accordance with the following Materials I.M. 320, 321, and 337 . t.,,... rr ......... :.... .1.., ......r... -i r..:...i.:......rn... 11)11:10c1..,... —, r00 01(114 1.,... crc until SS -01014 HOT IYdI\ ASPHAIA (GYRATORY tvilX DESIGN FOR LOCAL SYSTE-... Page IS of-20 3. Acceptance, Correlation, and Quality Assurance Testing. The Contractor's quality control test results will be compared and correlated to the Engineer's test results on a regular basis using guidelines and tolerances set forth In Materials I.M. 208 Appendix C: 210; and 511. If satisfactory correlation exists between the Contractor's test results and the Engineer tests, the Contractor's results will be used. Disputes between the Contractor's and Engineer's lest results, on one sample or one test of one sample, will be resolved by repeated testing of the same sample or additional testing of another sample. When repealed and /or additional sampling fails to resolve a dispute, a third materials laboratory designated by the Contracting Authority will act as a reference laboratory and perform additional testing as necessary to resolve the dispute. The Engineer will select, at random, a split portion of one or more of the daily hot mix production samples. Some or ail of the samples selected will be tested in the materials laboratory designated by the Engineer. The Engineer will test as many of the samples as necessary to establish a correlation. The Engineer will select one daily set of cores at random each week. These will be tested at the materials laboratory designated by the Engineer. Cores from the initial production will also be tested by the Contractor and the Engineer for correlation and validation of results. 01014.05 METHOD OF MEASUREMENT ti _11 The Engineer will measure the quantities of the various items of work involved in placement of "inc; tj mixtures in accordance with the following provisions: A. Hot Mix Asphalt Mixtures `~ 1. Measurement by Weight (Mass). When measurement is by weight (mass), the quantity of mixture will be expressed to tons r� (megagrams) and determined from the weight (mass) of individual loads measured to the nearest 0.01 tons (0.1 Mg). Loads may be weighed in trucks, weigh hoppers, or from the weight (mass) from batch plants computed by count of batches in each truck and hatch weight (mass). Article 2001.07 of the Standard Specifications applies. The weights (mass) of various loads shall be segregated into the quantities for each pay item. 2. Measurement by Area. When payment is based on square yards (square meter), the area of each lot will be computed to the nearest 0.1 square yard (01 m2) from surface dimensions measured to the nearest 0.1 foot (30 mm). When the average measured width of the lot is equal to or greater than the plan width, the computed area will be based on the plan width. When the average measured width is less than plan width, the computed area will be based on the measured width. When constructing shoulders on a basis of payment of square yards (square meters), inspection of the profile and elevation will be based on the completed work relative to the pavement edge; the Contractor shall be responsible for the profile and elevation of the subgrade and for thickness. B. Asphalt Binder. The amount of asphalt binder used from batch plants, continuous plants, or drum mixing plants, shall be by stick measurement in the Contractor's storage tank or by in -line flow meter reading. The asphalt binder quantity added to the storage tank shall be computed from a supplier certified transport ticket accompanying each load. The quantity of asphalt binder not used in the work will be deducted. When the quantity of asphalt binder in a batch is measured by weight (mass) and is separately identified by automatic or semi - automatic printout, the Engineer may compute from this printout the quantity of asphalt hinder used.
