Verification • For aggregate gradation and asphalt binder content, the ratio of verification testing frequency to the minimum quality control testing frequency is 1:5. The Engineer performs at least 3 verification tests per lot. • . Using the t-test, the. Engineer compares quality control tests results for aggregate gradation and asphalt binder content with corresponding verification test results. The Engineer uses the average and standard deviation of sequential sublots for the comparison.

The Engineer determines maximum theoretical density (California Test 309)at the frequency specified for Test Maximum Density under California Test 375,Part 5.D. The Engineer reports the average of 3 tests from a single split sample. The Engineer prepares and tests a set of 3 briquettes for each stability determination. If the stability range is more than 12 points,the Engineer prepares new briquettes. Modify California Test 304, Part 2.132c: "After compaction in the mechanical compactor, cool to 140 degrees F f 5 degrees F by allowing the briquettes to cool at room temperature for 0.5 hour, then place the briquettes in the.oven at 140 degrees F for a minimum of 2 hours and not more than 3 hours." The Engineer determines the bulk density of each lab-compacted briquette under California Test 308, Method A, and theoretical maximum specific gravity under California Test 309. The Engineer determines the percent of maximum theoretical density from the average density of 3 cores you take from every 750 tons of production or part thereof divided. by the maximum theoretical density. • If the total paved thickness is.at least 0.15 foot and any lift is less than 0.15 foot, the Engineer determines the percent of maximum theoretical density from cores taken from the final lift measured the full depth of the total paved HMA thickness. • For any single quality characteristic for which a quality control factor, QFQci, is not determined, except smoothness, if 2 consecutive acceptance test.results do not comply with specifications: 1. Stop production. 2. Take corrective action. 3. In the.Engineer's presence, take samples and split each sample into 4 parts.. Test 1 part for compliance with the specifications and submit 3 parts to the Engineer. The Engineer tests 1 part for compliance with the specifications and reserves and stores 2 parts. 70 4. Demonstrate compliance with the specifications before resuming production and placement on the State highway. 39-4.05B STATISTICAL. . EVALUATION, DETERMINATION OF QUALITY FACTORS AND ACCEPTANCE Statistical Evaluation and Determination of Quality Factors • To determine the individual quality factor, QFQci, for any quality factor i = 1 through 5 or a lot's composite quality factor, QFC, for acceptance and payment adjustment, the Engineer uses the evaluation specifications under Section 39-4.03F, "Statistical Evaluation," and: 1. Verified quality control test results for aggregate gradation, 2. Verified quality.control test results for asphalt binder content 3. The Engineer's test results for percent of maximum theoretical density Lot Acceptance Based on Quality Factors • The Engineer accepts a lot based. on, the quality factors determined for aggregate gradation and asphalt binder content, QFQci for i = 1 through 4, using the total number of verified quality control test result values and the total percent defective (PU+PJ • The Engineer accepts a lot based on the quality factor determined for maximum theoretical density, QFQC5, using the total number of test result values from cores and the total percent defective (PU+PL). • The Engineer calculates the quality factor for the lot, QFC, which is a composite of weighted individual quality factors, QFQci, determined for each quality characteristic in the table "HMA Acceptance—QC /QA" in Section 39-4.05A, "General." • The Engineer accepts a lot based on quality factors if:: 1. The current composite quality factor, QFC, is 0.90 or greater 2. Each individual quality factor, QFQci for i =3, 4, and 5, is 0.90 or greater 3. Each individual quality factor, QFQci'for i = 1 and 2, is 0.75 or greater • No single quality characteristic test may represent more than the smaller of 750 tons or 1 day's production. Payment Adjustment • If a lot is accepted, the Engineer adjusts payment with the following formula: n PA= HMACP*wi+[QFQci*(HMATT-WHMA +WHAM TT]-(HMACP*HAM 7-7) i=1 ' where: PA.= Payment adjustment rounded to 2 decimal places. HMACP;= HMA contract price. HMA TT- HMA total tons represented in.the lot. WHMATTi Total tons of waived quality characteristic HMA. QFQci Running quality factor for the individual quality characteristic. 71 QFQC, for i =1 through 4 must be from verified Contractor's QC results. QFQC5 must be determined from the Engineer's results on cores taken for percent of maximum theoretical density determination. W = Weighting factor listed in the HMA acceptance table. i = Quality characteristic index number in the HMA acceptance table. • If the payment adjustment is a negative value, the Engineer deducts this amount from payment. If the payment adjustment is a positive value, the Engineer adds this amount to payment. • When the 21st sequential sublot becomes the 1 st sublot in the moving average, the previous 20 sequential sublots become a lot for which the Engineer determines a quality factor. The Engineer uses this quality factor to pay for.the HMA in the lot. The 215`sublot becomes the Ist sublot (n= 1) in the next lot. If the next lot consists of less than 5 sublots, these sublots must be added to the previous sublots for quality factor determination using 21 to 24 sublots. 39-4.05C DISPUTE RESOLUTION • For percent of maximum theoretical density dispute resolution: 1.

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 106 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. • 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 conerete 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..

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 witli 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 'acompressive strength at the maximum curing age specified ed;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 i 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.

The State maintains a list of sources of fine and coarse aggregate that have been approved for use with a reduced amount of supplementary cementitious material in the total amount of cementitious material to be used. A source of aggregate will be considered for addition to the approved list if the producer of the aggregate submits to the Transportation Laboratory certified test results from a qualified testing laboratory that verify the aggregate complies with the requirements. Before the testing starts, the aggregate test shall be. registered with the State. .A registration number can be obtained by calling (916) 227-7228. The registration number shall be used as the identification for the aggregate sample in correspondence with the State. Upon request, a split of the tested sample shall be provided to the State. Approval of aggregate will depend upon compliance with the.specifications, based on the certified test results submitted, together with any replicate testing the State may elect to perform. Approval will expire 3 years from the date the most recent registered and evaluated sample was collected from the aggregate source. Qualified testing laboratories shall conform to the following requirements: 1. Laboratories performing ASTM Designation: C 1293 shall participate in the Cement and Concrete Reference Laboratory (CCRL) Concrete Proficiency Sample Program and shall have received a score of 3 or better on each test of the previous 2 sets of concrete samples. 2. Laboratories performing ASTM Designation: C 1260 shall participate in the Cement and Concrete Reference Laboratory (CCRL) Pozzolan Proficiency Sample Program and shall have received a score of 3 or better on the shrinkage and soundness tests.of the previous 2 sets of pozzolan samples. Aggregates on the list shall conform to one of the following requirements: 1. When the aggregate is tested in conformance with the requirements in California Test 554 and ASTM Designation: C 1293, the average expansion at one year shall be less than or equal to 0.040 percent; or 160 2, When the aggregate is tested in conformance with the requirements.in California Test 554 and ASTM Designation: C 1260, the average of the expansion at 16 days shall be less than or equal to 0.15 percent. If the aggregates used. in the concrete are on the Department's list, the minimum amount of supplementary cementitious material shall conform to the following: 1. If fly ash or natural pozzolan conforming to the provisions in Section 90-2.01 C, "Required Use of Supplementary Cementitious Materials," of the Standard Specifications is used, the minimum amount of supplementary cementitious material shall be 15 percent by weight of the total cementitious material; or 2. If silica fume conforming to the provisions in Section 90-2.01C, "Required Use of Supplementary Cementitious .Materials," of the Standard Specifications is used, the minimum amount of supplementary cementitious material shall be 7 percent by weight of the total cementitious material. The limitation on tricalcium silicate (C3S) content :in Type II cement specified in Section 90-2.01A; "Cement," of the Standard Specifications shall not apply. The 13`h paragraph in Section 90-1.01 "Description" is amended to read: If any.concrete has a cementitious material, portland cement, or mineral admixture content that is less than the minimum required, the concrete shall be removed. However, if the Engineer determines that the concrete is structurally adequate, the concrete may remain in place and the Contractor shall pay to the State$0.50 for each pound of cementitious material, portland cement, or mineral admixture that is less than the minimum required. The Department may deduct the amount from any moneys due, or that may become due, the Contractor under the contract. The deductions will not be made unless the difference between the contents required and those actually provided exceeds the batching tolerances permitted by Section 90-5, "Proportioning." No deductions will be made based on the results of California Test 518. The 7th and 8'h paragraphs of Section 90-2.02 "Aggregates", of the Standard Specifications are amended to read: If the re§ults. of either or both the Cleanness Value and coarse aggregate grading tests do not meet the requirements specified for "Contract Compliance," the concrete that is represented by the tests shall be removed.. However, if the Engineer determines that the concrete is structurally adequate, the concrete may remain in place, and the Contractor shall pay to the State.$7.00 per cubic yard for paving concrete and $11.00 per cubic yard for all other concrete for the;concrete represented by these tests and left in place. The Department may deduct the amount from any moneys due, or that may become due, the Contractor under the contract: If the results of either or both the Sand Equivalent and fine aggregate grading tests do not meet the requirements specified for "Contract Compliance," the concrete which is represented by the tests shall be removed. However, if the Engineer determines that the concrete is structurally adequate, the concrete may remain in place, and the Contractor shall pay to the State $7.00 per cubic yard for paving concrete and'$11.00 per cubic yardfor all other 161 concrete for the concrete represented by these tests and left in place. The Department may deduct the amount from any moneys due, or that may become due, the Contractor under the contract. The fourth paragraph of Section 90-6.01, "General",is amended as follows: Uniformity of concrete mixtures will be determined by variations in the results of AASHTO Tests T-119-99 (Slump Cone) and T-141-97 (Sampling) and by variations in the proportion of coarse aggregate. as determined by California Test 529. At the Engineer's option, California Test 533 (Penetration)may be used to corroborate other test results. The first paragraph of Section 90-6.06, "Amount of Water and Penetration," is amended to read as follows: The amount of water used in concrete mix shall be regulated so that the consistency of the concrete as determined by AASHTO Tests T-119-99 (Slump Cone) and T-141-97 (Sampling) is within minus 2 inches to plus 1 inch of the slump designated in the mix design. Batches of concrete with a slump outside the range shown shall not be used in the work.. At the Engineer's option, California Test 533 may be used in lieu of AASHTO Tests T-119- 99 and T-141-97•or may be used to corroborate the AASHTO test results. The 4`h and 5th paragraphs of Section 90-9.01 "General" of the Standard Specifications are superseded by the following: 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 28-day compressive strength test is below the specified strength, but is 95 percent or more of the specified strength, the Contractor shall, at the Contractor's expense, .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 $20.00 per cubic yard of concrete represented by the. deficient test. If the result of a single 28-day compressive strength test is below 95 percent of the specified strength, but is 85 percent or more of the specified strength, the Contractor shall make the aforementioned corrections and pay to the State $75.00 per cubic yard of concrete represented by the deficient test. In addition, such corrective changes, subject to the approval of the Engineer, shall be made when the compressive strength of concrete tested at 7 days is below 70 percent of the required compressive strength at 28 days .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 a 28-day compressive strength below the specified strength, but 85 percent or more of the specified strength, payments to the State as required above shall be made. If the test result indicates a 28-day compressive strength below 85 percent, the concrete represented by such test will be rejected, unless the Contractor, at his expense, obtains. and 162 submits evidence acceptable to the.Engineer that the strength and quality of the concrete placed in the work are acceptable.. If such evidence `consists of test made on cores taken from the work, the cores shall be obtained and tested in accordance with the specifications of ASTM Designation: C42. If the Contractor submits acceptable evidence that the concrete exceeds 85% of the specified strength, the Contractor shall pay to the State $75.00 per cubic yard of concrete represented by the testing regardless of a result by the Contractor's retest that exceeds 95% of the specified strength. In all cases,the Contractor shall obtain and submit the evidence to the Engineer no later than 5 working days after notification by the State of the State's 28-day compressive strength test results. The Contractor shall be responsible for all cost incurred by the State to obtain, monitor, and/or review evidence submitted by the Contractor. No test taken 5 working days after notification of the results of the state's 28-day compressive strength test shall be allowed as evidence that the strength and quality of the concrete is acceptable.

The number of significant figures used in the calculations must comply-with AASHTO R-11, Absolute Method. • Determine the percentage of work not in compliance with the specification limits for each. quality characteristic as follows: 1. Calculate the arithmetic mean(X) of the test values Ex X=— n where: x= individual test values n= number of test values 2. Calculate the standard deviation • where: j(x2) sum of the squares of individual test values (ZX)2 = sum of the individual test values squared n= number of test values 3. Calculate the upper quality index (Qu) /� _ USL- X Qu S where: USL = target value plus the production tolerance or upper specification limit s = standard deviation X arithmetic mean 4. Calculate the lower quality index(QL); X - LSL where: LSL= target value minus production tolerance or lower specification limit S = standard deviation X = arithmetic mean 5. From the table, Upper Quality Index QU or Lower Quality Index QL, of this Section 39- 4.03F, "Statistical Evaluation", determine Pu; where: PU= the estimated percentage of work outside the,USL. PU= 0, when USL isnot specified.. 6.

During Cast In Place Detectable/Tactile Warning Surface Tile installation procedures,ensure adequate.safety guidelines are in place and that they are in accordance with the applicable industry and government standards. B. The specifications of the structural embedment flange system and'related materials shall be in strict accordance with the contract documents and the guidelines set by their respective manufacturers. Not recommended for asphalt applications. C. The physical characteristics of the concrete shall be consistent with the contract specifications while maintaining a slump range of 4-7 to permit solid.placement of the Cast In Place Detectable/Tactile Warning Surface Tile system. An overly wet mix will cause the tile to float. Under these conditions,suitable weights such as 2 concrete blocks or,sandbags(25 Ib)'shall be placed on each tile. D. Prior to placement of the Cast In Place Detectable/Tactile Warning Surface Tile system,the contract drawings shall be reviewed. E.. The concrete pouring and finishing operations require typical mason's tools,however, a 4'long level with electronic slope readout, 25 Ib.weights,and a large non-marring rubber mallet are specific to the installation of the Cast In Place Detectable/Tactile Warning Surface Tile system. A vibrating mechanism such as that manufactured by Vibco can be employed,if desired. The vibrating unit should be fixed to a soft base such as wood,at least 1 foot square.,, F. The factory-installed plastic sheeting must remain in place during the entire installation process to prevent the splashing of concrete onto the finished surface of the tile. G. When preparing to set the tile,it is important that NO concretebe removed in the area to accept the tile. It is imperative that the installation technique eliminates any air voids under the tile. Holes;in the tile perimeter allow air to escape during the installation process. Concrete will flow through the large holes in each embedment flange on the underside of the tile. This will lock the tile solidly into the cured concrete. H. :The concrete shall be poured and finished true and smooth to the required dimensions and slope prior to the tile placement. Immediately after finishing concrete,the electronic level should be used,to check that the required slope is achieved. The tile shall be placed true and square to the curb edge in accordance with the contract drawings. The Cast In Place Detectable/Tactile WarningSurface Tiles shall be tamped(or_vibrated)into the-fresh concrete to ensure that the field level of the tile is flush to the adjacent concrete surface. The embedment process should not be accomplished by stepping on the tile as this may cause uneven setting which can result in air voids under the tile surface. The contract drawings indicate that the the field level(base of truncated dome)is flush to adjacent surfaces to permit proper water drainage and eliminate tripping hazards between adjacent finishes. I. In cold weather climates it is recommended that the Cast In Place DetectableRactile Warning Surface Tiles be set deeper such that the top of domes are level to the adjacent concrete on the top and sides of ramp and that the base of domes to allow water drainage. This installation will reduce the possibility of damage due to.snow clearing operations. J. Immediately after placement,the the elevation is to be checked to adjacent concrete.-The elevation and slope should be set consistent with contract drawings;to permit water drainage to curb as the design dictates. K.

The Vitrified Polymer Composite(VPC) Cast In Place Detectable/Tactile Warning Surface Tile specified is based on Armor-Tile manufactured by Engineered Plastics Inc. (800-682-2525). Existing engineered and field tested products, which have been in successful service for a period of three (3) years are subject to compliance with requirements, may be incorporated in the work and shall meet or exceed the specified test criteria and characteristics. B. Color: Yellow conforming to Federal Color No. 33538. Color shall be homogeneous throughout the tile. Tiles are also available in Light Grey(Federal Color No. 26280), Dark Grey (Federal Color No. 36118), Onyx Black (Federal Color No. 17038), Pearl White(Federal Color No. 37875), Brick Red (Federal Color No. 22144), Ocean Blue(Federal Color No. 15187), Ochre Yellow(Federal Color No. 23594), and Colonial Red (Federal Color No. 20109). PART 3 EXECUTION 3.01 INSTALLATION A. During Cast In Place Detectable/Tactile Warning Surface Tile installation procedures, ensure adequate safety guidelines are in place and that they are in accordance with the applicable industry and government standards. B. Prior to placement of the Cast In Place Detectable/Tactile Warning Surface Tile system, review manufacturer and contract drawings with the Contractor prior to the construction and refer any and all discrepancies to the Engineer. C. The specifications of the structural embedment flange system and related materials shall be in strict accordance with the contract documents and the guidelines set by their respective manufacturers. Not recommended for asphalt applications. D. The physical characteristics of the concrete shall be consistent with the contract specifications while maintaining a slump range of 4-7 to permit solid placement of the Cast In Place Detectable/Tactile Warning Surface Tile system. An overly wet mix will cause the tile to float. Under these conditions, suitable weights such as 2 concrete blocks or sandbags (25 Ib)shall be placed on each tile. E. The concrete pouring and finishing operations require typical mason's tools, however, a 4' long level with electronic slope readout, 25 Ib.weights, and a large non-marring rubber mallet are specific to the installation of the Cast In Place Detectable/Tactile Warning Surface Tile system. A vibrating mechanism such as that manufactured by Vibco can be employed, if desired. The vibrating unit should be fixed to a soft base such as wood, at least 1 foot square. F. The factory-installed plastic sheeting must remain in place during the entire installation process to prevent the splashing of concrete onto the finished surface of the tile. G. When preparing to set the tile, it is important that no concrete be removed in the area to accept the tile. It is imperative that the installation technique eliminates any air voids under the tile. Holes in the tile perimeter allow air to escape during the installation process. Concrete will flow through the large holes in each embedment flange on the underside of the tile. This will lock the tile solidly into the cured concrete. ADA Cast In Place Tactile Tiles February 2006 a H. The concrete shall be poured and finished true and smooth to the required dimensions and slope prior to the tile placement. Immediately after finishing concrete, the electronic level should be used to check that the required slope is achieved. The the shall be placed true and square to the curb edge in accordance with the contract drawings. The Cast In Place Detectable/Tactile Warning Surface Tiles shall be tamped (or vibrated) into the fresh concrete to ensure that the field level of the the is flush to the adjacent concrete surface. The embedment process should not be accomplished by stepping on the tile as this may cause uneven setting which can result in air voids under the the surface. The contract drawings indicate that the tile field level (base of truncated dome) is flush to adjacent surfaces to permit proper water drainage and eliminate tripping hazards between adjacent finishes. I. In cold weather climates it is recommended that the Cast In Place Detectable/Tactile Warning Surface Tiles be set deeper such that the top of domes are level-to the adjacent concrete on the top and sides of ramp and that the base of domes to allow water drainage. This installation will reduce the possibility of damage due to snow clearing operations. J. Immediately after placement, the tile elevation is to be checked to adjacent concrete. The elevation and slope should be set consistent with contract drawings to permit water drainage to curb as the design dictates. Ensure that the field surface of the tile is flush with the surrounding concrete and back of curb so that no ponding is possible on the tile at the back side of curb. K. While concrete is workable, a 3/8" radius edging tool shall be used to create a finished edge of concrete, then a steel trowel shall be used to finish the concrete around the tile's perimeter, flushto the field level of the tile. L. During and after the tile installation and the concrete curing stage, it is imperative that there is no walking, leaning or external forces placed on the tile that may rock the tile causing a void between the underside of tile and concrete. M. Following tile placement, review installation tolerances to contract drawings and adjust tile before the concrete sets. Two suitable weights of 25 lb each may be required to be placed on each tile as necessary to ensure solid contact of the underside of tile to concrete. N. Following the concrete curing stage, protective plastic wrap is to be removed from the tile surface by cutting the plastic with a sharp knife, tight to the concrete/tile interface. If concrete bled under the plastic, a soft brass wire brush will clean the residue without damage to the tile surface. O. If desired, individual tiles can be bolted together using %inch or equivalent hardware. This can help to ensure that adjacent tiles are flush to each other during the installation process. Tape or caulking can be placed on the underside of the bolted butt joint to ensure that concrete does not rise up between the tiles during installation. Any protective plastic wrap which was peeled back to facilitate bolting or cutting, should be replaced and taped to ensure that the tile surface remains free of concrete during the installation process. P. Tiles can be cut to custom sizes, or to make a radius, using a continuous rim diamond blade in a circular saw or mini-grinder. Use of a straightedge to guide the cut is advisable where appropriate. Q. Any sound-amplifying plates on the underside of the tile, which are dislodged during handling or cutting, should be replaced and secured with construction adhesive. The air gap created between these plates and the bottom of the tile is important in preserving the sound on cane audible properties of the Armor-Tile system as required in various jurisdictions. 3.02 CLEANING, PROTECTING AND MAINTENANCE A. Protect tiles against damage during construction.period to comply with Tactile Tile manufacturer's specification. B. Protect tiles against damage from rolling loads following installation by covering with plywood or hardwood. C. Clean Tactile Tiles not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean Tactile Tile by method specified by Tactile Tile manufacturer. D. Comply with manufacturers maintenance manual for cleaning and maintaining tile.surface and it is recommended to perform annual inspections.for safety and tile integrity.

Written unit prices, item totals and lump sums will be interpreted according to the number of digits and, if applicable, decimal placement. Cents symbols also have no significance in establishing any unit price or item total since all figures are assumed to be expressed in dollars and/or decimal fractions of a dollar. Bids on lump sum items shall be item totals only; if any unit price for a lump sum item is included in a bid and it differs from the item total,the items total shall prevail. The foregoing provisions for the resolution of specific irregularities cannot be so comprehensive as to cover every omission, inconsistency, error or other irregularity which may occur in a bid. Any situation not specifically provided for will be .determined in the discretion of the Agency, and that discretion will be exercised in the manner deemed by the Agency to best protect the public interest in the prompt and economical completion of the work.. - The decision of Agency respecting the amount of a bid, or the existence or treatment of an-irregularity in a bid, shall be final.

(a) By their signatures in Section 2,effective on the above date,these parties promise and agree as set forth in this contract,incorporating by these references the material in Section 1,SPECIAL TERMS. (b) Contractor shall, at his own cost and expense, and in a workmanlike manner, fully and faithfully perform and complete the work; and will furnish all materials,labor,services and transportation necessary,convenient and proper in order fairly to perform the requirements of this contract,all strictly in accordance with the Public Agency's plans,drawings and specifications and in accordance with the accepted bid proposal. (c) The work can be changed only with Public Agency's prior written order specifying such change and its cost agreed to by the parties;and the Public Agency shall never have to pay more than specified in Section 7,PAYMENT,without such an order. 4. TIME, NOTICE TO PROCEED. Contractor shall start this work as directed in the specifications or the Notice to Proceed;and shall complete it as specified in Section 1,SPECIAL TERMS. 5. LIQUIDATED DAMAGES. If the Contractor fails to complete.this contract and this work within the time fixed therefor,allowance being made for contingencies as provided herein,he becomes liable to the Public Agency for all its loss and damage therefrom;and because,from the nature of the case, it is and will be impracticable and extremely difficult to ascertain and fix the Public Agency's actual damage from any delay in performance hereof, it is agreed that Contractor will pay as liquidated damages to the Public Agency the reasonable sum specified in Section 1, SPECIAL TERMS,the result of the parties' reasonable endeavor to estimate fair average compensation therefor, for each calendar day's delay in finishing said work; and if the same be not paid,Public Agency may, in addition to its other remedies,deduct the same from any money due or to become due Contractor under this contract. If the Public Agency for any cause authorizes or contributes to a delay,suspension of work or extension of time,its duration shall be added to the time allowed for completion,but it shall not be deemed a waiver nor be used to defeat any right of the Agency to damages for non-completion or delay hereunder. Pursuant to Government Code Section 4215, the Contractor shall not be assessed liquidated damages for delay in completion of the work,when such delay was caused by the failure of the Public Agency or the owner of a utility to provide for removal or relocation of existing utility facilities. 6. INTEGRATED DOCUMENTS. The plans,drawings and specifications or special provisions of the Public Agency's call for bids,and Contractor's accepted bid for this work are hereby incorporated into this contract;and they are intended to cooperate,so that anything exhibited in the plans or drawings and not mentioned in the specifications.or special provisions,or vice versa,is to be executed as if exhibited,mentioned and set forth in both, to the true intent and meaning thereof when taken all together, and differences of opinion concerning these shall be finally determined by Public Agency's Agent specified in Section 1,SPECIAL TERMS. 7. PAYMENT: (a) For his strict and literal fulfillment of these promises and conditions,and as full compensation for all this work,the Public Agency shall pay the Contractor the sum specified in Section 1,SPECIAL TERMS,except that in unit price contracts that payment shall be for finished quantities at unit bid prices. (b) On or about the first of each calendar month,the Contractor shall be paid for all work done through the 15th of the preceding calendar month, as determined by Public Agency,minus 10%thereof pursuant to Public Contract Code Section 9203,but not until defective work and materials have been removed,replaced,and made good. 8.PAYMENTS WITHHELD. (a) The Public Agency or its Agent may withhold any payment,or because of later discovered evidence nullify all or any certificate for payment,to such extent and period of time only as may be necessary to protect the Public Agency from loss because of: (1) Defective work not remedied,or uncompleted work,or (2) Claims filed or reasonable evidence indicating probable filing,or (3) Failure to properly pay subcontractors or for material or labor,or (4) Reasonable doubt that the work can be completed for the balance then unpaid,or (5) Damage to another contractor,or (6) Damage to the Public Agency,other than damage due to delays. (b) The Public Agency shall use reasonable diligence to discover and report to the Contractor,as the work progresses,the materials and labor which are not satisfactory to it,so as to avoid unnecessary trouble or cost to the Contractor in making good any defective work or parts. (c) 35 calendar days after the Public Agency files its notice of completion.of the entire work,it shall issue a certificate to the Contractor and pay the balance of the contract price after deducting all amounts withheld under this'contract, provided the contractor shows that all claims for labor and materials have been paid,no claims have been presented to the Public Agency based on acts or omissions of the Contractor,and no liens or withhold notices have been filed against the work or site,and provided there are not reasonable indications of defective or missing work or of late-recorded notices of liens or claims against Contractor. 9.
