PART 1/COUNTY/DVBE
GENERAL INFORMATION REGARDING COMPLIANCE WITH DISABLED VETERANS BUSINESS ENTERPRISE (DVBE) PROGRAM 1.
Disabled Veterans Business Enterprises will be afforded full opportunity to submit bids in response to this invitation. DVBE firms bidding as prime contractors will automatically meet the stated Disabled Veterans Business Enterprise (DVBE) participation.
2.
Certified DVBE Information is available at the California State Department of General Services (DGS), Procurement Division (PD), Office of Small Business and DVBE Services (OSDS) website: Information can be viewed or downloaded from: http://www.dgs.ca.gov/pd/Programs/OSDS.aspx
COUNTY DISABLED VETERANS BUSINESS ENTERPRISE PROGRAM 1.
Board of Supervisors Policy B-39a Board of Supervisors Policy B-39a states that Disabled Veterans Business Enterprises (DVBEs) will be afforded maximum opportunity to compete for all County contracts; provides for the establishment of DVBE participation goals; and requires that potential contractors demonstrate a "good faith effort" if the goals are not achieved on a particular contract. The policy can be downloaded at: http://www.sdcounty.ca.gov/cob/docs/policy/B-39a.pdf.
2.
Objectives The following DVBE participation is imposed to recognize the service of disabled veterans to our country.
3.
DVBE Participation for the Project DVBE participation of three percent (3%) of Bid amount is required for a public work project estimated (by the County) to exceed $1 million. A good faith effort cannot be accepted in lieu of meeting the 3% requirement. A bidder who fails to meet this requirement shall be declared non-responsive and the next lowest responsible and responsive bidder that complies with this requirement will be awarded the contract. For a public work project that is estimated (by the County) to be between $500,000 and $1 million, the prime contractor shall make a good faith effort to meet-or-exceed 3% DVBE subcontractor participation requirement. The Good Faith Effort shall be documented in accordance with this bid document or the bidder may be deemed non-responsive. For a public work project estimated (by the County) to be less than $500,000, DVBE participation is encouraged, but not required. DVBE participation may be documented on page 2-10, but is not required at this estimate level.
7/14
1-7
PART 1/COUNTY/DVBE
4.
DVBE Subcontractor Documentation The bidder shall designate all licensed subcontractors in accordance with the instructions on the form titled DESIGNATION OF SUBCONTRACTORS contained in Part II of these Contract Documents. Designation of Subcontractors is due at the time of bid. In addition, the bidder shall include information regarding DVBE prime contractors, subcontractors, and vendors (material suppliers and service providers) on the BIDDER DVBE INFORMATION form (page 2-10), which is due within 2 business days of the Bid opening. "Good Faith Effort Documentation" shall be submitted in accordance with Item 7 below.
5.
Credit Toward Participation for DVBE Prime Contractors, Subcontractors and Vendors A DVBE prime contractor automatically meets a DVBE participation for a project. If the Prime is not a DVBE, compliance with 3% DVBE participation shall be calculated by taking the aggregate value of all DVBE subcontracts to be used on the project as a percentage of the total value of each such County contract. Participation amounts to a DVBE must be for a commercially useful function, as that term is defined in California Military and Veterans Code § 999(b)(5(B).
6.
Good Faith Effort Defined a.
A bidder who fails to meet the stated DVBE participation requirement for this project shall have made a good faith effort to meet it prior to the time bids are submitted.
b.
In evaluating the good faith effort of a bidder, the Owner shall consider the following criteria: 1)
The bidder solicited certified DVBEs to perform work or provide supplies or services for the project. Good faith effort shall include direct solicitation of individual certified DVBEs. Record of firms solicited shall be included in the Documentation of Good Faith Effort submittal. Solicitations conducted must be documented in the Documentation of Good Faith Effort. DVBE firms solicited must be licensed for appropriate work on this project, and must be physically located within the County of San Diego, or have indicated they would consider work in San Diego Service Region 11. Good Faith Efforts not adequately documented shall be considered nonresponsive.
7/14
2)
Where DVBE bids were rejected, the bidder provided the reasons for the rejections. If no bids received from DVBEs, the bidder shall so indicate in the Documentation of Good Faith Effort submittal.
3)
Contact with local DVBE organizations to identify DVBE firms is encouraged but is not a requirement for the Documentation of Good Faith Effort submitted to the Owner.
4)
Due to relatively short project solicitation periods, the Owner does not require advertising in trade and focus publications as a condition of satisfying the good faith effort for the DVBE participation. Advertising alone without direct solicitation of DVBE firms as required in paragraph 1) above does not satisfy the Good Faith Effort. 1-8
PART 1/COUNTY/DVBE
7.
Good Faith Effort Documentation For public work projects estimated (by the County) to be between $500,000 and $1 million where DVBE requirement has not been established, all bidders, are required to submit the Documentation of Good Faith Effort (pages 2-12 through 2-14; and supporting documentation) in addition to the BIDDER DVBE INFORMATION for (page 2-10), within 2 business days of the bid opening. When the stated DVBE participation is met, only the BIDDER DVBE INFORMATION form (page 2-10), contained in these Contract Documents, is required within two business days of the bid opening. Bidders are cautioned that even if their BIDDER DVBE INFORMATION form (page 2-10) indicates the stated DVBE participation is met, all bidders should still consider submitting Documentation of Good Faith Effort. Submittal of satisfactory Documentation of Good Faith Effort will protect eligibility for award for those public work projects estimated (by the County) between $500,000 and $1 million in the event the County, in its review, finds that the stated DVBE participation has not been met. The DVBE Good Faith Effort must be submitted on the DOCUMENTATION OF GOOD FAITH EFFORT forms (pages 2-12 through 2-14) contained in these Contract Documents, or on equivalent formats acceptable to the County, and shall include sufficient supporting documentation to validate the solicitations conducted.
8.
Protest Procedure for DVBE A bidder who does not attain the stated project DVBE participation or has not made a "good faith effort" in accordance with these bid document instructions may be declared non-responsive. A bidder so declared may file a protest in writing with the Director, Department of Purchasing and Contracting within five (5) business days of the notification of the declaration, in accordance with Board of Supervisor Policy A-97 “Protest Procedures for Award of Contract” located at: http://www.sdcounty.ca.gov/cob/docs/policy/A-97.pdf
9.
DVBE Certification Eligible contractors, subcontractors and vendors wishing to participate as DVBEs on this project must be certified by the California State Department of General Services (DGS), Procurement Division (PD), Office of Small Business and DVBE Services (OSDS), and have a current certification on the date bids are opened. Information regarding certification and certified DVBEs can be obtained by visiting the Department of General Services site at: http://www.pd.dgs.ca.gov/pd
10.
DVBE Reporting Contractors, regardless of DVBE participation, shall report DVBE utilization in “Final Report – Utilization of Disabled Veterans Business Enterprises (DVBE)” contained in Part VIII of these Contract Documents.

No part of the track shall be closer than one foot from the edge of pavement. • In case of visible cracking of, or other damage to the pavement, operation of the paving equipment on the pavement shall be immediately discontinued. • Damage to the pavement resulting from early use of pavement by the Contractor's equipment as provided above shall be repaired by the Contractor. • The State will furnish the molds and machines for testing the concrete for modulus of rupture, and the Contractor, at the Contractor's expense, shall furnish the material and whatever labor the Engineer may require. 90-9 COMPRESSIVE STRENGTH 90-9.01 GENERAL • Concrete compressive strength requirements consist of a minimum strength that shall be attained before various loads or stresses are applied to the concrete and, for concrete designated by strength, a minimum strength at the age of 28 days or at the age otherwise allowed in Section 90-1.01, "Description." The various strengths required are specified in these specifications or the special provisions or are shown on the plans. • The compressive strength of concrete will be determined from test cylinders that have been fabricated from concrete sampled in conformance with the requirements of California Test 539. Test cylinders will be molded and initially field cured in conformance with California Test 540. Test cylinders will be cured and tested after receipt at the testing laboratory in conformance with the requirements of California Test 521. A strength test shall consist of the average strength of 2 cylinders fabricated from material taken from a single load of concrete, except that, if any cylinder should show evidence of improper sampling, molding, or testing, that cylinder shall be discarded and the strength test shall consist of the strength of the remaining cylinder.

PART 6/COUNTY
• When concrete compressive strength is specified as a prerequisite to applying loads or stresses to a concrete structure or member, test cylinders for other than steam cured concrete will be cured in conformance with Method 1 of California Test 540. The compressive strength of concrete determined for these purposes will be evaluated on the basis of individual tests. • When concrete is designated by 28-day compressive strength rather than by cementitious material content, the concrete strength to be used as a basis for acceptance of other than steam cured concrete will be determined from cylinders cured in conformance with Method 1 of California Test 540. If the result of a single compressive strength test at the maximum age specified or allowed is below the specified strength but is 95 percent or more of the specified strength, the Contractor shall make corrective changes, subject to approval of the Engineer, in the mix proportions or in the concrete fabrication procedures, before placing additional concrete, and shall pay to the State $10 for each in-place cubic yard of concrete represented by the deficient test. If the result of a single compressive strength test at the maximum age specified or allowed is below 95 percent of the specified strength, but is 85 percent or more of the specified strength, the Contractor shall make the corrective changes specified above, and shall pay to the State $15 for each in-place cubic yard of concrete represented by the deficient test. In addition, such corrective changes shall be made when the compressive strength of concrete tested at 7 days indicates, in the judgment of the Engineer, that the concrete will not attain the required compressive strength at the maximum age specified or allowed. Concrete represented by a single test that indicates a compressive strength of less than 85 percent of the specified 28-day compressive strength will be rejected in conformance with the provisions in Section 6-1.04, "Defective Materials." • If the test result indicates that the compressive strength at the maximum curing age specified or allowed is below the specified strength, but is 85 percent or more of the specified strength, payments to the State as required above shall be made, unless the Contractor, at the Contractor's expense, obtains and submits evidence acceptable to the Engineer that the strength of the concrete placed in the work meets or exceeds the specified 28-day compressive strength. If the test result indicates a compressive strength at the maximum curing age specified or allowed below 85 percent, the concrete represented by that test will be rejected, unless the Contractor, at the Contractor's expense, obtains and submits evidence acceptable to the Engineer that the strength and quality of the concrete placed in the work are acceptable. If the evidence consists of tests made on cores taken from the work, the cores shall be obtained and tested in conformance with the requirements in ASTM Designation: C 42. • No single compressive strength test shall represent more than 320 cubic yards. • If a precast concrete member is steam cured, the compressive strength of the concrete will be determined from test cylinders that have been handled and stored in conformance with Method 3 of California Test 540. The compressive strength of steam cured concrete will be evaluated on the basis of individual tests representing specific portions of production. If the concrete is designated by 28-day compressive strength rather than by cementitious material content, the concrete shall be considered to be acceptable whenever its compressive strength reaches the specified 28-day 7/14

PART 6/COUNTY
compressive strength provided that strength is reached in not more than the maximum number of days specified or allowed after the member is cast. • When concrete is specified by compressive strength, prequalification of materials, mix proportions, mixing equipment, and procedures proposed for use will be required prior to placement of the concrete. Prequalification shall be accomplished by the submission of acceptable certified test data or trial batch reports by the Contractor. Prequalification data shall be based on the use of materials, mix proportions, mixing equipment, procedures, and size of batch proposed for use in the work. • Certified test data, in order to be acceptable, shall indicate that not less than 90 percent of at least 20 consecutive tests exceed the specified strength at the maximum number of cure days specified or allowed, and none of those tests are less than 95 percent of specified strength. Strength tests included in the data shall be the most recent tests made on concrete of the proposed mix design and all shall have been made within one year of the proposed use of the concrete. • Trial batch test reports, in order to be acceptable, shall indicate that the average compressive strength of 5 consecutive concrete cylinders, taken from a single batch, at not more than 28 days (or the maximum age allowed) after molding shall be at least 580 pounds per square inch greater than the specified 28-day compressive strength, and no individual cylinder shall have a strength less than the specified strength at the maximum age specified or allowed. Data contained in the report shall be from trial batches that were produced within one year of the proposed use of specified strength concrete in the project. Whenever air-entrainment is required, the air content of trial batches shall be equal to or greater than the air content specified for the concrete without reduction due to tolerances. • Tests shall be performed in conformance with either the appropriate California Test methods or the comparable ASTM test methods. Equipment employed in testing shall be in good condition and shall be properly calibrated. If the tests are performed during the life of the contract, the Engineer shall be notified sufficiently in advance of performing the tests in order to witness the test procedures. • The certified test data and trial batch test reports shall include the following information: A. Date of mixing. B. Mixing equipment and procedures used. C. The size of batch in cubic yards and the weight, type, and source of all ingredients used. D. Penetration or slump (if the concrete will be placed under water or placed in cast-in-place concrete piles) of the concrete. E. The air content of the concrete if an air-entraining admixture is used. F. The age at time of testing and strength of all concrete cylinders tested. • Certified test data and trial batch test reports shall be signed by an official of the firm that performed the tests. • When approved by the Engineer, concrete from trial batches may be used in the work at locations where concrete of a lower quality is required and the concrete will be paid for as the type or class of concrete required at that location. 7/14
6-95
PART 6/COUNTY
• After materials, mix proportions, mixing equipment, and procedures for concrete have been prequalified for use, additional prequalification by testing of trial batches will be required prior to making changes that, in the judgment of the Engineer, could result in a strength of concrete below that specified. • The Contractor's attention is directed to the time required to test trial batches and the Contractor shall be responsible for production of trial batches at a sufficiently early date so that the progress of the work is not delayed. • When precast concrete members are manufactured at the plant of an established manufacturer of precast concrete members, the mix proportions of the concrete shall be determined by the Contractor, and a trial batch and prequalification of the materials, mix proportions, mixing equipment, and procedures will not be required. 90-10 MINOR CONCRETE 90-10.01 GENERAL • Concrete for minor structures, slope paving, curbs, sidewalks and other concrete work, when designated as minor concrete on the plans, in the specifications, or in the contract item, shall conform to the provisions specified herein. • The Engineer, at the Engineer's discretion, will inspect and test the facilities, materials and methods for producing the concrete to ensure that minor concrete of the quality suitable for use in the work is obtained. 90-10.02 MATERIALS • Minor concrete shall conform to the following requirements: 90-10.02A CEMENTITIOUS MATERIAL • Cementitious material shall conform to the provisions in Section 90-1.01, "Description." 90-10.02B AGGREGATE • Aggregate shall be clean and free from deleterious coatings, clay balls, roots, and other extraneous materials. • Use of crushed concrete or reclaimed aggregate is acceptable only if the aggregate satisfies all aggregate requirements. • The Contractor shall submit to the Engineer for approval, a grading of the combined aggregate proposed for use in the minor concrete. After acceptance of the grading, aggregate furnished for minor concrete shall conform to that grading, unless a change is authorized in writing by the Engineer. • The Engineer may require the Contractor to furnish periodic test reports of the aggregate grading furnished. The maximum size of aggregate used shall be at the option of the Contractor, but in no case shall the maximum size be larger than 1 1/2-inch or smaller than 3/4-inch. • The Engineer may waive, in writing, the gradation requirements in this Section 90-10.02B, if, in the Engineer's opinion, the furnishing of the gradation is not necessary for the type or amount of concrete work to be constructed. 7/14

Permanent impacts to O.003-acre (16.5-linear feet) of non-wetland waters of the United States (U.S.) and/or State will be caused by roadway improvements and related facilities. The Project will also cause temporary impacts of O.036-acre (640-linear feet) to non-wetland waters of the U.S. and/or State. Unavoidable impacts will be mitigated through the onsite establishment of O.006-acres (37 linear feet) of streambed and the onsite restoration of O.036-acre (640-linear feet) of streambed. Project impacts and mitigation are summarized in the following table:

Re-establishment is defined as the return of natural/historic functions to a site where vegetated or unvegetated waters of the U.S. and/or State previously existed (e.g., removal of fill material to restore a drainage). Rehabilitation is defined as the improvement of the general suite of functions of degraded vegetated or unvegetated waters of the U.S. and/or State (e.g., removal of a heavy infestation or monoculture of exotic plant species from jurisdictional areas and replacing with native species). Enhancement is defined as the improvement to one or two functions of existing vegetated or unvegetated waters of the U.S. and/or State (e.g., removal of small patches of exotic plant species from an area containing predominantly natural plant species). Preservation is defined as the acquisition and legal protection from future impacts in perpetUIty of eXisting vegetated or unvegetated waters of the U.S. and/or State (e.g., conservation easement). L Mitigation site monitoring must continue until the mitigation site has met the success criteria stated in the mitigation plan(s). The mitigation site must be maintained free of non-native and invasive plant species and maintained in accordance with specified success criteria in perpetuity

STATEMENT OF COMPLIANCE
CEM-2503 (Modified by County of San Diego DPW 08/20 t0) InsÍuctions
This statement of compliance meets needs of the state and federal payroll requirements to pay fringe benefits in addition to payment of the minimum rates. The contractor's obligation to pay fringe benefits may be met by payment of the fringes to the various preapproved plans, funds, or programs or by making these payments directly to the employees as part of their weekly wage payments. The contractor must show on the face of his or her payroll all monies paid to the employees whether as basic rates or total hourly wage amount in lieu of fringes. The contractor shall report in the statement of compliance that he or she is paying to others fringes required by the contract and not paid directly to the employees in lieu of fringes. Detailed instructions follow:
Contractors required to pay Federal Wage Rates: Such a contractor shall check paragraph 2(a) of the statement to indicate that the wage rates for laborers or mechanics contained in the payroll are not less than the applicable wage rates specified in the applicable wage determination incorporated into the contract.
Contractors required to pay the State Prevailing Wage Rates as determined by the Director of lndustrial Relations: Such a contractor shall check paragraph 2(b) of the statement to indicate that the wage rates for laborers or mechanics contained in the payroll are not less than the applicable wage rates determined by the Director of lndustrial Relations for the county or counties in which the work is preformed.
Gontractor who pay all required fringe benefits: A contractor who pays fringe benefits to approved plans, funds, or programs in amounts not less than were determined in the applicable wage decisions shall continue to show on the face of his or her payroll the basic hourly rate and overtime rate paid to his or her employees, just as he or she has always done. Such a contractor shall check paragraph 4(a) of the statement to indicate that he or she is also paying approved plans, funds, or programs within the times required for the receipt of those sums, not less than the amount predetermined as fringe benefits for each craft. Any exception shall be noted in Section 4(c).
Contractors who pay no fringe benefits: A contractor who does not pay fringe benefits to an approved plan shall pay a like amount to the employee. This payment cari be reported by inserting in the straight time hourly rate column of his or her payroll an amount not less than the predetermined rate for each classification plus the amount of fringe benefits determined for each classification in the applicable wage decision. lnasmuch as it is not necessary to pay time and a half on wages paid in lieu of fringes, the overtime rate shall be not less than one and one-half the basic predetermined rate, plus the required cash in lieu of fringes at the straight time rate. To simplify computation of overtime, it is suggested that the straight time basic rate and payment in lieu of fringes be separately stated in the hourly rate column. ln addition, the contractor shall check paragraph 4(b) of the statement to indicate that he or she is paying fringe benefits directly to his or her employees. Any exceptions shall be noted in Section 4(c). Use of Section 4(c), Exceptions: Any contractor who is making payment to approved plans, funds, or programs in amounts less than the wage determination required is obligated to pay the deficiency directly to the employees as wages in lieu of fringes. Any exceptions to Section 4(a) and 4(b), whichever the contractor may check, shall be entered in Section 4(c). Enter in the Exception column the craft, and enter in the Explanation column the hourly amount paid the employees as wages in lieu of fringes, and the hourly amount paid to plans, funds, or programs as fringes.
