Consider a resolution authorizing the Mayor to enter into an agreement for the West Wastewater Treatment Plant Rehabilitation Project. STAFF RESOURCE PERSON: Jim Nuse STAFF RECOMMENDATION: In order to improve the cost efficiencies of the West (old) Wastewater Treatment Plants and replace worn out equipment the first phase of this plant rehabilitation has been designed and bids received. These improvements include the replacement of blowers which have been extremely costly to operate. The balance of the project includes piping modifications and improvements to the post thickener. These improvements will change the treatment process of the plant from "conventional" activated sludge to "complete mix" activated sludge. THis change in process will enable this plant to discharge the lower ammonia /nitrogen requirements recently required by EPA and the Texas Water Commission in the most cost effective manner. Staff recommends award to Pensick Construction. Pensick has performed well on many other projects for Round Rock. CITY OF ROUND ROCK WASTEWATER TREATMENT PLANT WEST 1987 C.I.P.

It is the intent of this Agreement that there shall be no delay in the execution of the work, and the decision or directions of the Engineer as rendered shall • be promptly carried out. 2.02 Right of Engineer to Modify Methods and Equipment. If at any time the methods or equipment used by the Contractor are found to be unsafe or inadequate to secure the quality of the work or the rate of progress required under this Contract, the Engineer may direct the Contractor in writing to increase their safety or improve their character and 'efficiency and to cease operations under this Contract until such direction is complied with. No claims shall be made against the Owner for damages caused by any delay resulting from such order. -3- If they increase the amount of work and the increased work can fairly be classified under the specifications, such increase shall be paid for according to the quantity actually done and at the unit price established for such work under this Contract; otherwise such work shall be paid for as provided under Section 2.12 "Extra Work ". In the event the Owner shall make such changes or alterations which will make useless any work already done or material already furnished or used in said work, then the Owner shall compensate the Contractor for any materials or labor so used, for any actual loss occasioned by such change, and for the actual expenses incurred in preparation for the work as originally planned. 2.04 Damages. The right of general supervision by the Owner shall not make the Contractor an agent of the Owner, and the liability of the Contractor for all damages to persons, firms, and corporations arising from the Contractor's execution of the work shall not be lessened because of such general supervision. The Contractor is an independent contractor in regard to work under this Contract, and as such is solely liable for all damages to any persons, firms, corporations, or their property as a result of the prosecution of the work. 2.05 Losses from Natural Causes. All loss or damage arising out of the nature of the work to be done or from the action of the elements or from any unforseen circumstances in the prosecution of the work or from unusual obstructions or difficulties which may be encountered in the prosecution of the work shall be sustained and borne by the Contractor at his own cost and expense. 2.06 Laws and Ordinances. The Contractor shall at all times observe and comply with all Federal, State, and local laws, ordinances, rules and regulations which in any manner affect the Contract or the work and shall idemnify and save harmless the Owner against any claim arising from the violation of any such laws and ordinances whether by the Contractor or his employees or his subcontractors and their employees. 2.07 Licenses, Permits and Certificates.

The Contractor shall protect and save harmless the Owner from all and every demand for damages, royalties, or fees on any patented invention used by him in connection with the work done or material furnished under this Contract; provided, however, that if any patented material, machinery, appliance, or invention is clearly specified in this Contract, the cost of procuring the rights of use and the legal release of idemnity shall be borne and paid by the Owner direct unless such cost is determined and directed to be included in the bid price at the time the Proposal is submitted. 2.09 Keeping of Plans and Specifications Accessible. The Engineer shall furnish the Contractor with two (2) sets of executed Plans and Specifications without expense to him, the Contractor shall keep one copy of the same constantly accessible on the job site, with the latest revisions noted thereon, and additional sets will be obtained from the Engineer at commercial reproduction rates plus 20% for handling. 2.10 Discrepancies and Omissions. It is further agreed that it is the intent of this Contract that all work must be done and all material must be furnished in accordance with the generally accepted practice, and in the event of any discrepancies between the separate contract documents, the priority of interpretation defined under "Contract Documents" shall govern. In the event that there is still any doubt as to the meaning and intent of any portion of the Contract, Specifications or Drawings, the Engineer shall define which is intended to apply to the work. 2.11 Contractor's Understanding. It is understood and agreed that the Contractor has, by careful examination, satisfied himself as to the nature and location of the work, the conformation of the ground, the character, quality and quantity of the materials to be encountered, the character of equipment and facilities need preliminary to and during the prosecution of the work, the general and local conditions, and all other matters which can in any way affect the work under this contract. No verbal agreement or conversation with any officer, agent, or employee of the Owner, either before or after the execution of this Contract, shall affect or modify any of the terms or obligations herein contained. 2.12 Extra Work. The term "extra work" as used in this Contract shall be understood to mean and include all work that may be required by the Owner through the Engineer to be done by the Contractor to accomplish any change, alteration, or addition to the work shown by the Plans or reasonably implied by the Specifications and not covered by the Contractor's Proposal, except as provided in Section 2.03 - "Changes and Alterations ". It is agreed that the Contractor shall perform all extra work under the direction of the Engineer when presented with a written Change Order signed by the Engineer. -5- No claim for extra work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve extra work for which he should receive compensation, he shall make a written request to the Engineer for a written Change Order authorizing such extra work. Should a difference of opinion arise as to what does or does not constitute extra work or concerning the payment therefor and the Engineer insists upon its performance, the Contractor shall proceed with the work after making a written request for a written Change Order and shall keep an accurate account of the "actual field cost" thereof as provided under Method "C" below. 2.13 Payment for Extra Work. It is agreed that the compensation to be paid by the Contractor for performing extra work shall be determined by one or more of the following methods: Method "A" - By agreed unit prices; Method "B" - By agreed lump sum; or Method "C" - If neither Method "A" or Method "B" can be agreed upon before the extra work is commenced, then the Contractor shall be paid the "actual field cost" of the work plus 15%. Where extra work is performed under Method "C ", the term "actual field cost" of such extra work is hereby defined to be and shall include: (a) the payroll cost for all workmen, such as foreman, mechanics, craftsmen, and laborers; (b) the cost of all materials and supplies not furnished by the Owner; (c) rental for all power- driven equipment at agreed -upon rates for the time actually employed or used in the performance of the extra work; (d) transportation charges necessarily incurred in connection with any equipment authorized by the Engineer for use on said extra work and which is not already on the job; (e) all power, fuel, lubricants, water, and similar operating expenses; (f) all incidental expenses incurred as a direct result of such extra work including sales or use taxes on materials, payroll taxes, and the additional premiums for construction bonds, workmen's compensation, public liability and property damage, and other insurance required by the Contract where the premiums therefor are based on payroll and material costs. The Engineer may direct the form in which accounts of the "actual field costs" shall be kept and may also specify in writing before the work commences the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be incorporated in the written extra work Change Order. The 15% of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, and general superintendence. 2.14 Assignment and Subletting. The Contractor shall not assign or sublet the work or any part thereof without the previous written consent of the Engineer, nor shall he assign, by power of attorney or otherwise, any of the money payable under this contract unless by and with the consent of the Owner to be signified in like manner. If the Contractor assigns all or any part of any monies due or to become due under this Contract, the instrument of assignment shall contain a clause substantially to the effect that it is agreed that the right of the assignee in and to any monies due to to become due to the Contractor shall be subject to all prior liens of all persons, firms, and corporations for services rendered or materials supplied for the performance of the work called for in this Contract. 2.15 Subcontractors. The Contractor shall be as fully responsible to the Owner for the acts and omissions of his subcontractors and of persons either directly or indirectly employed by them as he is for the acts and omissions of persons directly employed by him. Should any subcontractor fail to perform the work undertaken by him in a satisfactory manner, his subcontract shall be immediately terminated by the Contractor upon written notice from the Engineer. - 2.16 Owner's Status. Nothing contained in this Contract shall create any contractual relation between any subcontractor and the Owner. 2.17 Completed Portions of Work. The Owner shall have the right to take possession of and to use any completed or partially completed portions of the work prior to completion of the entire work, but such use shall not constitute an acceptance of any of the work not completed in accordance with the Contract Documents. If the Engineer determines that taking possession of and using partially completed work substantially increases the cost of or delays construction, the Contractor shall be entitled to extra compensation or extension of time or both as determined by the Engineer. 2.18 Materials. All materials furnished by the Contractor shall be as required by the Plans and Specifications or as otherwise stipulated. The Contractor shall not start delivery of materials which he is to furnish until the Engineer has approved the source of supply of such materials. 2.19 Receiving and Storage of Materials. The Contractor shall make arrangements for receiving and storing materials. The Owner will not sign for or receive shipments of materials consigned to the Contractor. The Owner will not furnish storage space for materials except where written permission is given by the Engineer. -7- 2.20 "Or Equal" Clause. Whenever a material, product, or article is specified or shown on the Plans by using the name of the proprietary product or of a particular manufacturer or vendor and is followed by the term "or equal" the Contractor may submit a written request to the Engineer requesting approval of the use of a material, product, or article he feels is truly equal to the one specified. The Engineer will evaluate the request to determine if the material, product, or article is of equal substance and function and if it will perform identically the duties imposed by the general design. Written approval of an "or equal" material, product, or article must be obtained from the Engineer before it may be incorporated into the work as a substitute for that specified in the Contract Documents. 2.21 Completed Work. The Contractor shall maintain continuous adequate safeguards to protect all completed work from damage, loss, or the intrusion of foreign elements. 2.22 Materials Furnished by the Owner. The Contractor shall assume responsibility for and safeguard any and all materials supplied by the Owner against loss or injury. This provision shall extend to the taking of all necessary sanitary precautions to avoid contamination of such materials that must be maintained and incorporated into the work in a sanitary condition. 2.23 Protection of Property. The Contractor shall give reasonable notice to the owner or owners of public or private property and utilities when such property is liable to injury or damage through performance of the work, and he shall make all necessary arrangements with such owner or owners relative to the removal and replacement or protection of such property or utilities. The Contractor shall satisfactorily shore, support, and protect any and all structures, and all pipes, sewers, drains, conduits, and other facilities belonging to the Owner, and he shall be responsible for any damage resulting thereto. The Contractor shall not be entitled to any damages or extra pay as a result of any postponement, interference, or delay caused by any such structures and facilities being on the line of the work whether they are shown on Plans or not. 2.24 Shelters for workmen and Materials.

The Contractor shall give the Engineer full information in advance as to his plans for carrying on any part of the work. If at any time prior to the start or during the progress of the work any part of the Contractor's plant or equipment or any of his methods of executing the work appear to the Engineer to be unsafe, inefficient, or inadequate to insure the required quality or rate of progress of the work, the Engineer may order the Contractor to increase or improve his facilities or methods, and the Contractor shall promptly comply with such orders; failure to comply will result in placing Contractor in abandonment per Section 8 "Abandonment of Contract by Contractor "; but neither compliance with such orders nor failure of the Engineer to issue such orders shall release the Contractor from his obligation to secure the degree of safety, the quality of work, and the rate of progress required by this Contract.

However, if the Owner stops the work for any other reason, the Contractor shall be entitled to reimbursement paid by the Owner for such expenses actually incurred which in the judgement of the Engineer occurred as a result of the work stoppage. Should delays repeatedly occur due to the Contractor's failure to provide adequate plant, equipment, or personnel, or where the Engineer determines that unreasonable inconvenience to the public is due to such failure, the Contractor's operations shall be suspended until he shall have provided adequate plant, equipment, and personnel to properly resume and continually prosecute the work. 5.05 Extensions of Time. Should the Contractor be delayed in the final completion of the work by any act or neglect of the Owner or Engineer, or of any employee or either, or by any other contractor employed by the Owner, or by strikes, fire or other cause or causes outside of and beyond the control of the Contractor and which the Engineer determines could have been neither anticipated nor avoided, then an extension of time sufficient to compensate for the delay as determined by the Engineer shall be granted by the Owner; provided, however, that the Contractor shall give the Owner prompt notice in writing of such cause of delay in each case. Extensions of time will not be granted for delays caused by unfavorable weather, unsuitable ground conditions or inadequate construction force. 5 06 Liquidated Damages for Failure to Complete on Time. The Contractor agrees that time is of the essence of this Contract and that the definite value of damages which would result from delay would be incapable of ascertainment and uncertain, so that for each day of delay beyond the number of days herein agreed upon for the completion of the work herein specified and contracted for, after due allowance for such extension of time as is provided for under the provisions of the preceding paragraph, the Owner may withhold permanently from the Contractor's total compensation, not as penalty but as liquidated damages, the sum of $500.00 per calendar day. -15- 6.

If the Contractor should abandon and fail to resume work within ten (10) days after written notification from the Owner or the Engineer or if the Contractor fails to comply with the orders of the Engineer when such orders are consistent with this Contract or with the specifications hereto attached, then the Contractor shall be deemed as having abandoned the Contract. The Surety on the bond shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. - 8.02 Retention of Contractor's Equipment and Materials by Owner. After receiving said notice of abandonment the Contractor shall not remove from the work any machinery, equipment, tools, materials, or supplies then on the job, but the same together with any materials and equipment under contract for the work may be held for use on the work by the Owner or the Surety on the performance bond or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefore except when used in connection with extra work where -18- . credit shall be allowed as provided for under Section 2.12 entitled "Extra Work ", it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and will be reflected in the final settlement. 8.03 Methods of Completing the Work. If the Surety should fail to commence compliance with the notice for completion herein before provided within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: a. The Owner may thereupon employ such force of workers and use such machinery, equipment, tools, materials, and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials, and supplies to said Contractor, and the expense so charged shall be deducted and paid by the Owner out of such monies as may be due or that may thereafter at any time become due to the Contractor under and by virtue of this Contract. In case such expense is less than the sum which would have been payable under this Contract if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this Contract if the same had been completed by said Contractor, then the Contractor or his Surety shall pay the amount of such excess to the Owner. b. The Owner under sealed bids, after fourteen (14) days notice published two (2) or more times in a newspaper having a general circulation in the county of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this Contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this Contract, such increase shall be charged to the Contractor, and the Surety shall be and remain bound therefor.

In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this Contract or when the Contractor or his Surety pay the balance shown to be due by them to the Owner, then all machinery, equipment, tools, materials, or supplies left on the site of the work shall be turned over to the Contractor or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials, or supplies on the site of the work, notice thereof together with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this Contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing or other giving of such notice such property shall be held by the Owner at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials, or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies which remain on the work and belong to persons other than the Contractor or his Surety to their proper owners. 9. MEASUREMENT AND PAYMENT 9.01 Character of Measurements. No extra or customary measurements of any kind will be allowed but the actual length, area, solid contents, number, and weight only shall be considered unless otherwise specifically provided. 9.02 Estimated vs. Actual Ouantities. Any and all estimated quantities stipulated in the proposal form under unit price items are approximate and are to be used only (a) as a basis for estimating the probable cost of the work and (b) for the purpose of comparing the proposals submitted for the work. It is understood and agreed that the actual amounts of work done and -20- materials furnished under unit price items may differ from such estimated quantities and that the basis of payment for such work and materials shall be for the actual amount of such work done and the actual quantity of materials furnished. The Contractor agrees that he will make no claim for damages, anticipated profits, or otherwise on account of any difference between the amount of work actually performed and materials actually furnished and the amounts estimated therefor in the proposal or other Contract Documents; provided, however, that if the actual quantity of any item should become as much as twenty -five (25%) percent more or twenty -five (25%) percent less than the estimated or contemplated quantity for such items, then either party to this Contract shall be entitled upon demand to a revised consideration on the portion of the work above or below twenty -five (25%) percent of the estimated quantity prior to initiating work or furnishing materials for the overrun or underrun quantities. Such revised consideration shall be determined by agreement between the parties or otherwise by the terms of this Contract as provided under Section 2.12 entitled "Extra Work ". 9.03 Payment.

The Contractor shall furnish to the Engineer by the twenty -fifth of the month such detailed information as he may request to aid him as a guide in the preparation of monthly estimates. On or about the first day of each month the Engineer will make an approximate estimate of the value of work done in conformity with the plans and specifications during the previous calendar month. After each such estimate shall have been approved by the Owner, the Owner shall pay to the Contractor ninety (90%) percent of the amount of such estimated sum on or before the 15th day of said month. -21- It is understood, however, that in case the whole work is near to completion and some unexpected or unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may, upon written recommendation of the Engineer, pay a reasonable and equitable portion of the retained percentage to the Contractor. 9.05 Certificates of Completion. Within ten (10) days after the Contractor has given the Engineer notice that the work has been completed the Engineer shall review the work and satisfy himself by examination that work has been finally and fully completed in accordance with the plans, specifications, and Contract. If so and if acceptance by Owner and all governmental entities having jurisdiction has been secured, the Engineer shall issue a Contract Completion Certificate to the Owner and the Contractor. Such certificate when issued shall constitute final acceptance of the work covered under this Contract and serve as the date for stoppage of the contract period specified for completion of the Project. 9.06 Final Estimate and Payment. After the Contract Completion Certificate has been issued the Engineer shall proceed to make final measurements and to prepare a final estimate of the work done and materials furnished under this Contract and the value thereof. The Engineer shall certify the Final Estimate and submit it to the Owner within five (5) days from the date of the Contract Completion Certificate; provided the Notarized Affidavit specified in Section 9.07 has been received by the Engineer. The Owner shall pay the Contractor within fifteen (15) days from the date of the Contract Completion Certificate the entire sum shown due on the certified Final Estimate prepared by the Engineer after deducting all amounts to be kept and retained under any provision of this Contract. However, it is to be specifically understood that the final payment will not be paid by the Owner to the Contractor under any circumstances until the Notorized Affidavit required by Section 9.07 entitled "Notarized Affidavit ", has been submitted to the Engineer. All prior estimates and payment shall be subject to correction in the final estimate and payment; but in the absence of error or manifest mistake, it is agreed that all estimates, when approved by the Owner, shall be conclusive evidence of the work done and materials furnished. 9.07 Notarized Affidavit. Before final payment for the work by the Owner the Contractor shall submit to the Engineer a notarized affidavit in duplicate stating under oath that all subcontractors, vendors, and other persons or firms who have furnished or performed labor or furnished materials for the work have been fully paid or satisfactorily secured. Such affidavit -22- shall bear or be accompanied by a statement, signed by the Surety Company who provided the performance bond for the work, to the effect that said Surety Company consents to final payment to the Contractor being made by the Owner. 9.08 Release of Liability. The acceptance by the Contractor of the last payment shall operate as and shall be a release to the Owner and every officer and agent thereof from all claims and liability hereunder for anything done or furnished for or relating to the work or for any act or neglect of the Owner or of any person relating to or affecting the work. 9.09 Contractor's Obligation. Neither the Contract Completion Certificate nor the final payment nor any provision in the Contract Documents shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required in the Contract Documents. 9.10 Payments Withheld. The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any payment to such extent as may be necessary to protect himself from loss on account of: a. Defective work not remedied. b. Claims filed or reasonable evidence indicating probable filing of claims. c. Failure of the Contractor to make payment properly to subcontractors or for material or labor. d. Damage to another contractor. When the above grounds are removed or the Contractor provides a Surety Bond satisfactory to the Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. -23- SPECIAL CONDITIONS OF THE AGREEMENT 1 SPECIAL CONDITIONS OF THE AGREEMENT SECTION 01 - INFORMATION 01 - ENGINEER 1 The word "Engineer" in these Specifications shall be understood as referring to HAYNIE KALLMAN & GRAY, I INC., 12303 -J- Technology Blvd., Austin, Texas 78727.

Any sheeting driven below the invert grade shall be left in place. The granting of such permission by the Engineer, however, shall not relieve the Contractor in any degree from his full responsibility under the Contract. Sheeting and bracing which are left in place must be removed for a distance of three feet (3') below the established finished grade or the existing surface, whichever is lower. Trench bracing, except that which must be left in place, may be removed when the backfilling has reached the respective levels of such bracing. Sheeting, except that which must be left in place, must be removed after the backfilling has been completed or has been brought up to such an elevation as 02 -6 1 1 to permit its safe removal. Sheeting and bracing may be removed before backfilling but only in such manner as will insure the adequate protection of the adjacent ' structures. 02 - TRENC 1 02 -14.1 C I Pipeline trenches shall be backfilled with designated materials to the level of the original ground surface, to the underside of the ground base course, to the finished grade, or as shown on the Plans. Before 1 backfilling, the trench shall be cleared of all timber and debris. Backfill shall be compacted to a minimum of 85% relative density, as determined by ASTM D4253 -83 and ' D4254 -83, except as otherwise provided herein. It is highly important that a dense, well- compacted II backfill be placed around the pipelines. The Contractor will be required to produce such a backfill under all circumstances. The materials used for the backfill, the amount of thereof, and the manner of deposition shall be I subject to the approval of the Engineer, but the Contractor will be held responsible for any displacement or instability of the pipeline or any damage to the I coating caused by improper installation of backfill materials. No material shall be used for trench backfill, which, for any reason cannot be compacted to I the degree specified. For these specifications, backfill shall be divided into two (2) categories: Bedding and Upper Level Backfill. I Bedding shall be defined as that material supporting and extending to 6" inches above the top of the pipe. Where concrete is specified to cover the pipe, the top of the I concrete shall be considered as the top of the bedding. Upper zone backfill shall be defined as that material placed in the trench from the top of the bedding to the upper limit of backfill required. 02 -14.2 Bedding I If soft, spongy, unstable, or other similar material is encountered upon which the bedding material or pipe is to be placed, this unsuitable material shall be removed ' to a depth ordered by the Engineer and replaced with bedding material suitably densified. Additional bedding so ordered, over the above amount required by the Plans ' or Specifications, will be paid for as provided in the 1 02 -7 General Conditions. If the necessity for such additional bedding materials has been caused by an act or failure to act on the part of the Contractor, or is required for the control of ground water, the Contractor shall bear the expense of the additional excavation and bedding. Bedding material shall first be placed, so that the pipe is supported for the full length of the barrel with full bearing on the bottom segment of the pipe equal to a minimum of 0.4 of the outside diameter of the barrel. Then the remainder of the bedding shall be placed. Alternate methods of pipe laying which are recommended by the pipe manufacturer may be used if approved by the Engineer. Except where otherwise specified, the material for the bedding envelop shall be as follows: a. All pipe smaller than six inches (6 "), regardless of pipe material, shall be bedded with sand, except that such pipe installed in trenches excavated by blasting shall be bedded in 3/8 -inch down washed gravel. b. All six inch (6 ") or larger pipe (except Ductile Iron under certain conditions described below) shall be bedded in either sand or 3/8 -inch down washed gravel, except that such pipe installed in trenches excavated by blasting shall be bedded in 3/8 -inch down washed gravel. c. All pipe of sixteen inch (16 ") or larger size (except Ductile Iron under conditions described below) shall be bedded in either sand or 3/8 -inch down washed gravel, except that such pipe installed in blasted trenches shall be bedded in either pea gravel or crushed stone. d. Where specifically approved by the Engineer, ductile iron pipe of six inch (6 ") and larger sizes may be bedded in selected excavated material from the trench excavation which meets the following graduation: SCREEN SIZE PERCENT RETAINED 1 -1/2" 08 1" 0 - 158 3/4" 15 - 50% 1/2" 40 - 70% 1/4" 70 - 90% 02 -8 02 -14.3 Unless otherwise specified, concrete used for bedding shall be Class 5.0 -B -2000. In cases where native free - draining granular material is suitable for use as bedding, the trench may be excavated to a point above the invert grade and the trench bottom hand - shaped so that the bottom segment of the pipe is firmly supported on undisturbed material. The pipe bedding over the top of the pipe shall be 6" minimum and shall be compacted to ninety -five (95) percent of the maximum density as determined by ASTM D 698 -78 unless otherwise shown on the Plans. Uppgr_Lgygl Backfill Backfill material for the upper level backfill zone of the pipe trench may include the excavated soil materials, except for rock cuttings or cobbles in excess of four inches (4 ") in their greatest dimension. The backfill shall have sufficient fines for compaction purposes and should have a Plasticity Index (P.I.) not exceeding 20 as determined by ASTM D4318 -83. The upper level backfill shall be compacted to 95 percent of the maximum dry density as determined by ASTM D 698 -78 (Standard Proctor) at a moisture content from minus one to plus two percent of the optimum moisture content. Jetting (water consolidation of backfill) shall be used only when approved by the Engineer. The jet pipe shall not be less than one and one - half (1 - 1/2) inches in diameter and shall extend to within fifteen inches (15 ") of the top of the pipe during jetting of backfill over pipe. The source of water for jetting shall be a water tank with a pressure of sixty pounds (60) per square inch. All "bridges" shall be completely broken down during the jetting process. Jet points along the line of the ditch shall be staggered from side to side at intervals not to exceed six feet (6') center to center or as necessary so that the backfill takes full possible subsidence while water is being introduced into it through the jet pipe. If the compaction requirements specified above are not met within 60 calendar days after jetting the backfill, the trench shall be re- excavated. Backfill material shall then be compacted by tamping and /or rolling until the compaction requirements are satisfied. 02 -9 For the special condition whereby backfill is required under areas to be paved, the upper level backfill shall be sand with a P.I. less than 12. This backfill shall be compacted to 95 percent of the maximum dry density as determined by ASTM D 698 -78 at a moisture content from minus one to plus two percent of the optimum moisture content. Jetting will be allowed under the direction of the Owner's representative. 02 -15 gTR0gTQRAI EXC AND BAcKFII 02 -15.1 Eggayatton The Contractor may employ any method of excavation that he desires which, in his experience, he considers to be the best, providing it meets with the approval of the Engineer. The ground shall not be dug by machinery nearer than three inches (3 ") of any finished subgrade without the express consent and approval of the Engineer. The last three inches (3 ") shall be removed by such methods acceptable to the Engineer, and shall not disturb or weaken any subgrade for foundation purposes. If after excavation to final grade of the basin structure foundations, dissimiliar foundation subgrade materials exist (i.e., soil and rock) the subgrade shall be over - excavated to an additional depth of two feet and two feet beyond the foundation limits and backfilled with a select fill. Unless otherwise specified, the select fill shall meet the following requirements: Qpgdgatig0_8n4lygip. Percent Passing gigye -Sipe 0 - 10 45 - 75 60 - 85 Cl4eeifig4tion_IDdicee Liquid Limit : less than 40 Plasticity Index: less than 12 Maximum Wet Ball Mill: 50 1 -3/4" No. 4 No. 40 The select fill shall be compacted in loose lifts not exceeding eight inches (8 ") to a minimum of 95 percent of ASTM D1557 -78 Method D maximum dry density at a moisture content of from minus two to plus two percent of optimum moisture content. 02 -10 Excavations for the footings, floor slabs and other structures shall be carried to the neat outside lines of such structures, as shown on -the Plans, plus one inch (1 ") in all horizontal directions, and the concrete to be poured therein shall be placed on or against the original undisturbed material whenever such a procedure is reasonably possible and expedient. If this is not possible, the earth on which the concrete is to be poured shall be compacted to a uniform density of not less than ninety -five (95) percent of the maximum density as determined by ASTM D- 698 -78. Excavations for walls, where forms are used, shall extend a sufficient distance to allow for placing and removal of forms, installations of services, and inspection of work. Structure excavation carried beyond or below the lines and grades indicated on the drawings shall be refilled with approved materials and compacted as directed by the Engineer at the expense of the Contractor, except that under footings, concrete shall be used. 02 - 15.2 B4ckd3lliug All lumber, rubbish and braces shall be carefully removed from excavations. Unless otherwise specified, all excavations shall then be backfilled with imported material up to the original surface of the ground, or to such grades as shall be directed. The backfilling shall be done as completely as possible in such manner as to prevent after - settlement. No backfill shall be placed against concrete walls until the walls have been inspected and approved by the Engineer. Shoring and sheeting shall be carefully and completely removed as the backfilling progresses, unless otherwise authorized by the Engineer. Where sheeting is left in place, all cavities behind such sheeting shall be solidly filled. Backfill material shall be placed in horizontal, uniform layers not exceeding eight inches (8 ") in thickness before compaction, and shall be brought up uniformly on all sides of the structure or facility. Each layer of backfill shall be compacted to a relative compaction of not less than 90 percent. 02 -11 Consolidation of structure backfill by ponding and jetting will be permitted when as determined by the Engineer, the backfill material is of such character that it will be self- draining when compacted and that foundation materials will not soften or be otherwise damaged by the applied water, and no damage to the structure from hydrostatic pressure will result. When ponding and jetting is permitted, material for use as structure backfill shall be placed and compacted in layers not exceeding four feet (4') in thickness. The work shall be performed without damage to the structure or softening of the embankment and in such a manner that excess water will not be impounded. Ponding and jetting methods shall be supplemented by the use of vibratory or other consolidation equipment when necessary to obtain the required consolidation. Backfill material shall be native material provided that no material larger than three inches (3 ") in greatest dimension shall be used. 02 -16 EARTHFILL QQNSTRUCTION 02 -16.1 general Earth fill construction shall consist of constructing embankments, including the preparation of the areas upon which they are to be placed, buttress fills, dikes, the placing and compacting of approved material within areas where unsuitable material exists in holes, pits and other depressions. Areas over which fills are to be placed shall be cleared of vegetation, scarified and then wetted and rolled prior to placing fill materials. When fills are to be placed over existing surface improvements which are to remain in place, such clearing and scarifying will not be required. When fill is to be made and compacted on hillsides or where new fill is to be compacted against existing fill or where embankment is built one -half width at a time, the slopes or original hillsides and old or new fills shall be benched a minimum of four feet (4') horizontally as the fill is placed. A new bench shall be started where the vertical cut for the next lower bench intersects the existing ground. Material thus cut out shall be recompacted along with the new embankment material at the Contractor's expense. 02 -12 Clods or hard lumps of earth of six inches (6 ") in greatest dimensions shall be broken up before compacting the material in embankment, with the following exception: When the fill material contains large rocks, boulders, or hard lumps (such as hardpan or cemented gravel which cannot be broken readily) over twelve inches (12 ") in greatest dimension, such materials may be incorporated in the fill only when authorized by the Engineer with respect to the acceptability of the material, the location and depth of its placement in the fill, and the method to be used. Embankments shall not be constructed when material is frozen or a blanket of snow prevents proper compaction. 02 -16.2 Compacting Fill shall be constructed in compacted layers of uniform thickness and each layer shall be compacted in accordance with the requirements herein specified with the following exception: Where fills are to be constructed across low, swampy ground which will not support the weight of hauling equipment, the lower part of the embankment may be constructed by dumping successive loads in a uniformly distributed layer of thickness not greater than that necessary to support the equipment while placing subsequent layers. The remainder of the embankment shall be constructed in layers and compacted as specified. The construction of dikes, the placing and compacting of approved material where unsuitable material has been removed, and the filling of holes, pits and other depressions, shall conform to all of the requirements specified herein for compacting fills. Trenches, holes, depressions and pits outside of areas where fills are to be constructed shall be graded to provide a presentable and well- drained area. Embankments shall be constructed so that each layer shall have a cross fall of at least two percent (2%) but no more than five percent (5%). 02 -13 The loose thickness of each lift of fill material shall not exceed nine (9) inches. Each lift shall be compacted to between 93% and 95% of the maximum dry density as determined by ASTM D698 -78 at a moisture content of not less than 2% dry nor more than 3% wet of optimum moisture content. The interstices around the rock in each layer shall be filled with earth or other fine material and compacted. Broken portland cement concrete and bituminous type pavement obtained from the project excavations will be permitted in the fill with the following limitations: 1. The maximum dimension of any piece used shall be six inches. 2. Pieces larger than four inches (4 ") shall not be _ placed within twelve inches (12 ") of any structure. 3. Pieces larger than three inches (3 ") shall not be placed within twelve inches (12 ") of the finished surface. 4. "Nesting" of pieces will not be permitted. At locations where it would be impractical to use mobil power compacting equipment, fill layers shall be compacted to the specified requirements by any approved method that will obtain the specified relative compaction. At the time of compaction, the moisture content of fill material shall be such that the specified relative compaction will be obtained and the fill will be firm,' hard and unyielding. Fill material which contains excessive moisture shall not be compacted until the material is dry enough to obtain the required relative compaction. Full compensation for any additional work involved in drying fill material to the required moisture content shall be considered as included in the contract price paid and no additional compensation will be allowed therefor. 02 -17 MEASMREMENT AND PAYMENT No separate payment for work performed under this Item. Include cost of same in Contract prices bid for all items of which this work is a component part. 02 -14 SECTION 03 - CONCRETE 03 -01 CENERAI Concrete consisting of portland cement, concrete aggregate, sand and water will be designated by a symbol consisting of two numbers.

Otherwise, the cement shall be delivered in original unopened sacks that have been filled by the manufacturer. They shall be plainly marked with the manufacturer's name or brand and cement type. Each sack shall contain 94 pounds of cement. Cement shall be stored in such a manner as to permit ready access for the purpose of inspection and sampling, and suitable protected against contamination or moisture. Should any cement show evidence of contamination, or be otherwise unsuitable, it shall not be used. All portland cement used in concrete for any individual structure shall be of the same brand and type unless otherwise approved by the Engineer. 03 - 04 AggRERTES Aggregates shall be sand and concrete aggregates conforming to the requirements prescribed in ASTM C -33 coarse aggregate graduation size number 467, and shall be approved by the Engineer prior to use. They shall meet the grading requirements of this subsection. Methods of handling materials resulting in segregation, degradation or the combining of materials which result in any stockpile failing to meet specifications, shall not be permitted. Aggregates which are found to have a silica - released alkali - reduced ratio greater than one, when tested in accordance with ASTM C289, may be used only when approved by the Engineer and provided low- alkali cement is used. Water used for concrete shall be clear and free from oil, vegetable matter and other deleterious substances. Water shall not contain an amount of impurities that will cause a change in the time of setting of portland cement or more than 25 percent nor a reduction in the compressive strength of mortar at fourteen days of more than 5 percent compared to results obtained with distilled water. 03 -2 In conventionally reinforced concrete work, water shall not contain more than 1,000 ppm of chlorides calculated as Cl, nor more than 1,000 ppm of sulfates calculated as SO 4 . In non - reinforced concrete work, water shall not contain more than 2,000 ppm of chlorides calculated as Cl, no more than 1,500 ppm of sulfates calculated as SO 03 -06 ADMIXTyRES Air entrainment shall be required on exposed plant walls or as directed by the Engineer.

Water reducer -set retarder admixture shall be used when average daily mean temperature is 75 °F. or more per ASTM C -494. No other admixtures of any type shall be used unless authorized by the Engineer. When an admixture is permitted or specified, it shall be measured accurately into each batch or load in liquid form by a mechanical dispensing device and method approved by the Engineer. 03 -07 PRQPQRTIQNINQ Aggregates and cement shall be proportioned by weight. Proportioning shall consist of combining the aggregates, each stored in a separate bin in the various gradations prescribed, with cement and water. Weigh hoppers shall be charged from bins located directly over them or from conveyor belts. When conveyor belts are used, there shall be a separate belt for each size aggregate. There shall be an approved moisture meter installed to indicate the moisture in the sand. Bulk cement shall be weighed in an individual hopper and shall be kept separate from the aggregates until the batch ingredients are discharge into the mixer drum. The cement hopper shall be attached to a separate scale for individual weighing. 03 -3 The amount of water to be added to the mixture shall be measured and discharged rapidly into the mixing drum through a valve with a positive cut -off. When water is measured by weight it shall be weighed on a separate scale. All weighing or metering devices, except moisture meters, used for proportioning materials shall be accurate to within one percent. They shall be sealed and certified by the recognized, legal Sealer of Weights and Measures. These certifications shall be dated within the past 12 months and shall be renewed whenever required by the Engineer. The moisture meter shall be accurate to within 1/2 of one percent moisture. Whenever portable bunkers are set up at a new location, the scale assemblies shall be inspected and certified regardless of the date of scales were last tested. Scales utilized in proportioning shall be either springless dial or multiple beam type. Scale graduations shall be no greater than the following: Aggregate Scales Cement Scales Water Scales 03 -4 25 lbs. 5 lbs. - 5 lbs. All scales shall be of such size and so arranged that they may be read easily from the operator's platform. If a multiple beam type scale is used, the scale shall be provided with an indicator operated by the main beam which will give positive visible evidence of over or under weight. The indicator shall be so designed that it will operate during the addition of the last 400 pounds of any weighing. The other travel of the indicator hand shall be at least one -third of the loading travel. Indicators shall be enclosed against moisture and dust. Weighing equipment shall be insulated against vibration and movement of the other operating equipment in the plant. When the entire plant is running, the scale reading at cut -off shall not vary from the weight designated the Engineer by more than one percent (1%) for cement, one percent (1 -1/2 %) for any size of aggregate, nor one percent (1 %) for the total aggregate in any batch. 03 -08 MIXINQ Machine mixing will be required in all cases other than those in which it would obviously prove to be impractical, in which event hand mixing will be permitted. Mixing shall be commenced as soon as possible after the cement is placed in contact with the aggregates, but in no event shall the intervening period exceed 30 minutes. All concrete mixers shall be of such design and construction and so operated as to provide a thoroughly and properly mixed concrete in which the ingredients are uniformly distributed. Mixers shall be maintained in proper and serviceable working condition and any part or portion thereof that is out of order, or becomes worn to such extent as to detrimentally affect the quality of mixing, shall be promptly repaired or replaced. 03 -09 QQNCRETE CONSISTENCY The amount of water added at the mixer shall be regulated to take into account the free water in the aggregates. Free water is defined as the total water . minus the water absorbed by the aggregate in a saturated surface -dry condition. The amount of water used in the mixture shall not exceed the minimum amount necessary to permit practical placement and consolidation of the concrete, and unless otherwise authorized by the Engineer, shall be that required to produce concrete with a slump within the range shown as nominal in the following table: Type of Work Nominal Slump Maximum Slump (inches) (inches) Concrete Pavement 0 -2 3 Non - reinforced Concrete 0 -3 4 Reinforced Concrete Structures Heavy Sections 0 -3 5 Thin Sections & Columns 0 -4 6 Concrete Placed under Water 6 -8 9 03 -5 The concrete used in the work shall not have a slump greater than that shown as maximum above, nor a free water content greater than 312 pounds per cubic yard of concrete. When adverse or difficult conditions affect the placement of concrete, the Engineer may authorize a greater slump to be used, provided both the water and cement are increased. Water shall be added at a ration not to exceed 30 pounds per sack of added cement per cubic yard of concrete, and such additional water and cement shall be at the Contractor's expense. The consistency of concrete shall be determined in accordance with ASTM C -143. If slump tests of individual samples taken at approximately the 1/4 and 3/4 points of the discharge differ by more than two inches (2 "), the mixer will not be accepted for further use until the condition is corrected. 03 - TRANSIT [+FIXERS The type, capacity, and manner of operation of the mixing and transporting equipment for ready -mix concrete shall conform to the current ASTM•C -94 standard; "Standards for Operation of Truck Mixers and Agitators of the National Ready -Mixed Concrete Association" and the "Truck Mixer and Agitators Standards of the Truck Mixer Manufacturers Bureau ". Transit mix concrete trucks shall be equipped with an automatic device for recording the number of revolutions of the drum during the mixing period. Each mixer and agitator shall have attached thereto in a prominent place, a metal plate or plates, installed by the manufacturer on which is plainly marked the capacity of the drum in terms of the volume of mixed concrete and the speed of rotation for the agitating and mixing speeds of the mixing drum or blades. Each mixer shall have an identification number painted on the truck in such a location that it can be easily read from the batching platform. The total volume of materials introduced into the mixer shall not exceed the manufacturer's guaranteed mixing capacity. If the concrete so mixed does not meet the uniformity requirements of this subsection, the amount of materials charged into the mixer shall be reduced. 03 -6 The drum of the mixer shall be completely emptied of any previously mixed load. The proper proportions of aggregate, cement, and water for each load of concrete shall be placed in the mixer and shall be mixed therein for not less than 70 nor more than 100 revolutions of the drum or blades at the speed designated by the manufacturer of the equipment as mixing speed. Additional revolutions of the drum shall be at the speed designated by the manufacturer of the equipment as agitating speed. The revolving of the drum shall be continuous until the concrete is completely emptied from the drum. When concrete is being placed for concrete structures, all wash water shall be emptied from the mixer before any portion of the succeeding load is placed therein. For all other work, the mixer shall be empty or may carry 10 gallons of water in the drum. Adequate control of ready -mixed concrete will sometimes require that additional water be added and mixed into the batch at the point of discharge. Water so added shall be mixed (3) minutes. Water shall not be added to the load during transit. The total elapsed time between the addition of water at the batch plant and discharging the completed mix shall not exceed 90 minutes. Under conditions contributing to quick setting, the total elapse time permitted may be reduced by the Engineer. The Engineer shall be provided with a legible certified weighmaster's certificate which shall contain the following information: Name of vendor Name of contractor Number of cubic yards in the load Actual weights of cement and of each size of aggregate Amount of water added at the plant Amount of water in the aggregate Brand and type of cement Brand and amount of admixture Time and date of batching 03 -7 1 Space shall be provided on the certificate so that ' amount of water added on the job may be indicated. 03 - HAND MIXING Hand mixed concrete shall be mixed on a water -tight platform or in a mortar box in batches not to exceed 1/3 cubic yard each. The aggregates shall first be spread in a uniform layer over which the required quantity of cement shall be evenly distributed. The entire batch ' shall be turned with shovels until the ingredients are thoroughly blended before adding the water. After adding the proper amount of water, the batch shall again be turned with shovels until a uniform consistency is obtained. Methods of hand mixing which allow the loss of mixing water will not be permitted. 03 -12 TRANSPORTING BATCHED MATERIALS AND MIXED CONCRETE The compartments of trucks or other equipment used for the purpose of transporting proportioned dry aggregate and cement, or mixed concrete, shall be suitably constructed to adequately protect and prevent loss or , leakage of the contents during charging, transit or discharging. 03 -13 STEEL REINFORCEMENT FOR CONCRETE ' 03 -13.1 General The following specifications set forth the requirements for bar, wire and wire mesh reinforcement.

Deficiencies in film thickness shall be corrected by the application of an additional coat of paint. On concrete, application rates will vary according to surface 08 -7 texture; however, in no case shall the manufacturer's stated coverage rate be exceeded. On porous surfaces, it shall be the painter's responsibility to achieve a protective and decorative finish either by decreasing the coverage rate or by applying additional coats of paint. Apply paint only when temperature and atmospheric conditions are favorable to drying and are such to preclude condensation on surfaces being painted. Do not apply paint when either surface or ambient temperatures are less than 50 degrees Fahrenheit or when a temperature drop of 20 degrees or below 50 degrees Fahrenheit is forecast. Do not apply paint to surfaces upon which there is frost or moisture, nor during misty or rainy weather unless specific approval is given. Drying time shall be construed to mean "under normal conditions ". Where conditions are other than normal because of the weather or because painting must be done in confined spaces, longer drying times will be necessary. Additional coats of paint shall not be applied nor shall units be returned to service until paints are thoroughly dry. After installation of machinery and electrical equipment, check base coats carefully and retouch all damaged surface areas. Do not paint nameplates, serial number bases, chrome or bronze trim, or any rotating parts.
