Such estimates shall be furnished promptly so as to occasion no delay in the Work, and shall be furnished at the Contractor's expense. The Contractor shall state in the estimate any extension of time required for the completion of the Work if the change or extra work is ordered.

51 General Conditions Engineer: Stantec Section Page 13 of The cost or credit to the Town resulting from a change in the Work shall be determined in one or more of the following ways: 1. by mutual acceptance of a lump sum properly itemized and supported by sufficient substantiating data to permit evaluation; 2. by unit prices stated in the Contract Documents or subsequently agreed upon; 3. by cost to be determined in a manner agreed upon by the parties and a mutually acceptable fixed or percentage fee; or 4. by the method provided in Section If none of the methods set forth in Section is agreed upon, the Contractor, provided he receives a written order signed by the Town, shall promptly proceed with the Work involved. The cost of such Work shall then be determined by the Town on the basis of the reasonable expenditures and savings of those performing the Work attributable to the change, including, in the case of an increase in the Contract Sum, a reasonable allowance for overhead and profit. In such case, and also under Section above, the Contractor shall keep and present an itemized accounting together with appropriate supporting data for inclusion in a Change Order. Unless otherwise provided in the Contract Documents, cost shall be limited to the following: actual cost of materials, including sales tax and cost of delivery; labor, including social security, old age and unemployment insurance, and fringe benefits required by agreement or custom; workers' or workmen's compensation insurance; bond premiums, and rental value of equipment and machinery. Pending final determination of cost to the Town, payments on account shall be made on the Town's Certificate for Payment. The amount of credit to be allowed by the Contractor to the Town for any deletion or change which results in a net decrease in the Contract Sum will be the amount of the actual net cost. When both additions and credits covering related Work or substitutions are involved in any one change, the allowance for overhead and profit shall be figured on the basis of the net increase, if any, with respect to that change Unit prices shall be as stated in the Bid Form and the Contract shall include all costs of the Contractor to the Town as listed in Section No additional charges shall be allowed for these items under any circumstances. 7.2 CONCEALED CONDITIONS Should concealed conditions encountered in the performance of the Work below the surface of the ground or should concealed or unknown conditions in an existing structure be at variance with the conditions indicated by the Contract Documents, or should unknown physical conditions below the surface of the ground or should concealed or unknown conditions in an existing structure of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in this Contract, be encountered, the Contract Sum shall be equitably adjusted by Change Order upon claim by either party made within twenty days after the first observance of the conditions. 7.3 MINOR CHANGES IN THE WORK The Town will have authority to order minor changes in the Work not involving an adjustment in the Contract Sum or an extension of the Contract Time and not inconsistent with the intent of the Contract Documents. Such changes shall be effected by written order, and shall be binding on the Town and the Contractor. The Contractor shall carry out such written orders promptly, regardless of whether it objects to an absence of adjustment in the Contract Time or Contract Sum. 7.4 CLAIMS FOR ADDITIONAL COSTS Definition. The word Claim shall mean a written demand by the Contractor for an increase in the Contract Time or the Contract Sum. The Contractor is responsible for substantiating its Claims. The word Claim shall not include claims by the Town. The Town may withhold from the Contractor the value of any claims against the Contractor in accordance with Massachusetts General Laws, including, but not limited to, Sections 39G and 39K of Chapter 30.

52 General Conditions Engineer: Stantec Section Page 14 of Time Limits on Claims.

This notice shall be given by the Contractor before proceeding to execute the Work, except in an emergency endangering life or property. No such claim shall be valid unless so made If the Contractor claims that additional cost is involved because of, but not limited to, (1) any written interpretation by the Town, (2) any order by the Town to stop the Work where the Contractor was not at fault, (3) any written order for a minor change in the Work issued or (4) failure of payment by the Town, the Contractor shall make such claim as provided in this Section 7.4. ARTICLE 8 - TIME 8.1 DEFINITIONS Unless otherwise provided, Contract Time is the period of time, including authorized adjustments, allotted in the Contract Documents for Substantial Completion of the Work The date of commencement of the Work is the date established in a notice to proceed. If there is no notice to proceed, it shall be the date of the Town-Contractor Agreement or such other date as may be established therein The Date of Substantial Completion of the Work or designated portion thereof is the Date certified by the Town when construction is substantially complete, in accordance with the Contract Documents, other than only customary punch list items, the lack of or completion of which will not interfere with the Town's use, so the Town can lawfully occupy and utilize the Work or designated portion thereof for the use for which it is intended. The Date of Final Completion of the Work is the date on which the Town issues its final Certificate for Payment in accordance with Section 9.9 hereof The term "day" as used in the Contract Documents shall mean calendar day unless otherwise specifically defined. 8.2 PROGRESS AND COMPLETION All time limits stated in the Contract Documents are of the essence of the Contract The Contractor shall begin the Work on the date of commencement as defined in Section He shall carry the Work forward expeditiously with adequate forces and shall achieve Substantial Completion within the Contract Time, and Final Completion thereafter in accordance with the provisions of the Contract Documents. If the Contractor fails to keep pace with the construction schedule prepared pursuant to Section 4.9, as measured by the certificates for payment issued by the Architect/Engineer, the Town may require the Contractor, at the Contractor s sole cost, to accelerate the progress of the work by adding personnel or increasing the hours of work or by other means acceptable to the Town. 8.3 DELAYS AND EXTENSIONS OF TIME If the Contractor claims that he is delayed at any time in the progress of the Work by any act or neglect of the Town or by any employee of the Town, or by any separate contractor employed by the Town, or by changes ordered in the Work, or by labor disputes, fire, unavoidable casualties, or any causes beyond the Contractor's or its Subcontractor's control, or by delay authorized by the Town, then, provided such delay in no way results from the act or neglect of the Contractor or any of its Subcontractors, the Contract Time may be extended by Change Order for such reasonable time as the Town may determine.

53 General Conditions Engineer: Stantec Section Page 15 of Any claim for extension of time shall be made in writing to the Town not more than seven (7) days after the commencement of the delay; otherwise it shall be waived. In the case of a continuing delay only one claim is necessary. The Contractor shall provide an estimate of the probable effect of such delay on the progress of the Work If no agreement is made stating the dates upon which interpretations of the Contract Documents by the Architect/Engineer shall be furnished, then no claim for delay shall be allowed on account of failure to furnish such interpretation until fifteen days after written request is made for them, and not then unless such claim is reasonable The Contractor hereby agrees that the Contractor shall have no claim for damages of any kind against the Town on account of any delay in the commencement or performance of the Work and/or any hindrance, delay or suspension of any portion of the Work, whether such delay is caused by the Town, or otherwise, except as and to the extent expressly provided under M.G.L. c.30, 39O in the case of written orders by the Town. The Contractor acknowledges that the Contractor's sole remedy for any such delay and/or suspension will be an extension of time as provided in this Article. 8.4 LIQUIDATED DAMAGES It is expressly understood and agreed, by and between the Contractor and Town, that the time for the completion of the Work described herein is a reasonable time for the completion of same, taking into consideration the average climatic range and usual industrial and/or residential conditions prevailing in this locality. If the said Contractor shall neglect, fail or refuse to substantially complete the Work within the times herein specified, or any proper extension thereof granted by the Town, then the Contractor does hereby agree, as a part consideration for the awarding of this Contract, to pay to the Town the amount specified in the Agreement not as a penalty but as liquidated damages for such breach of contract, for each and every calendar day that the Contractor shall be in default after the time stipulated for completing the Work. The said amount is fixed and agreed upon by and between the Contractor and the Town because of the impracticability of fixing and ascertaining the actual damages the Town would in such event sustain, and said amount is agreed to be the amount of damages which the Town would sustain and said amount shall be deducted by the Town from periodic payments. ARTICLE 9 - PAYMENTS AND COMPLETION 9.1 CONTRACT SUM The Contract Sum is stated in the Agreement and, including authorized adjustments, is the total amount payable by the Town to the Contractor for performance of the Work under the Contract Documents. 9.2 SCHEDULE OF VALUES Before the first Application for Payment, the Contractor shall submit to the Architect/Engineer a schedule of values allocated to various portions of the Work, prepared in such form and supported by such data to substantiate its accuracy as the Architect/Engineer may require. This schedule, unless objected to by the Architect/Engineer, in which case it shall be revised until acceptable to the Architect/Engineer shall be used as a basis for reviewing the Contractor's Applications for Payment. 9.3 APPLICATIONS FOR PAYMENT The Contractor shall submit to the Town an itemized Application for Payment supported by such data substantiating the Contractor's right to payment as provided elsewhere in the Contract Documents for the period ending the last day of each month within the Contract period. The Application shall contain a separate line item or section for each subtrade category and a listing of the amount paid to each subcontractor as of the date of the Application Such applications may not include requests for payment for portions of the Work for which the Contractor does not intend to pay to a Subcontractor or material supplier, unless such Work has been performed by others whom the Contractor intends to pay.

54 General Conditions Engineer: Stantec Section Page 16 of Unless otherwise provided in the Contract Documents, payments may be made on account of materials or equipment not incorporated in the Work but delivered and suitably stored at the site and, if approved in advance by the Town, payments may similarly be made for materials or equipment suitably stored at some other location agreed upon in writing. Payments for materials or equipment stored on or off the site shall be conditioned upon submission by the Contractor of bills of sale or such other procedures satisfactory to the Town to establish the Town's title to such materials or equipment or otherwise protect the Town's interest, including applicable insurance and transportation to the site for those materials and equipment stored off the site.

262 Chemical Root Control Engineer: Stantec Section Page 3 of 5 PART 2 PRODUCTS 2.01 CHEMICAL ROOT CONTROL AGENT A. General. A chemical root control agent designed specifically to control manhole and sewer line tree root intrusions shall be applied to manholes and sanitary sewers according to the following specifications. The chemical root control agent shall kill the root growth present in the manholes and pipelines and inhibit root re-growth without permanently damaging the vegetation producing the roots, and without disrupting wastewater treatment plant processes. 1. The chemical product shall contain an herbicide to destroy root tissue, an herbicide to deter regrowth, and a foaming surfactant to deliver the herbicides to the target root growths. It shall be currently registered with the U.S. EPA and the state pesticide regulatory agency. It shall be labeled for use in sewers and manholes to control tree roots. a. ROOT KILLING AGENT: The active component for destroying intruding roots in manholes and sanitary sewer lines shall be a potent, non-systemic toxin that kills contacted roots at low concentrations, but that will not permanently affect parts of the wastewater treatment plant distant from the treated roots. The active ingredient must be spontaneously detoxified by natural chemical or biochemical processes in a relatively short interval following its use. The active ingredient for destroying root intrusions shall be Sodium Methyldithiocarbamate at a concentration not less than 32.7%. b. ROOT RE-GROWTH INHIBITOR: The active ingredient for inhibiting regrowth of root intrusions in manholes and sanitary sewer lines shall inhibit root cell growth on contact, but shall not be transported so as to have a deleterious impact on treatment processes at the wastewater treatment plant. The material shall bind firmly to the soil in the vicinity of openings in manhole walls and pipe joints so as to form a persistent chemical barrier suppressing root tip growth. The material shall be sufficiently stable under the conditions of use to provide protection for twelve months or longer, but shall be subject to decomposition in wastewater treatment plants without disturbing the treatment plant processes. The root cell growth-inhibiting agent shall be 2,6-Dichlorobenzonitrile. c. INERT INGREDIENTS: The root control material shall be formulated with foaming agents and surfactants sufficient to produce a stable, small bubble, dense foam capable of sustaining its shape and remaining on the treated roots for approximately thirty minutes. The foaming surfactants shall strip grease that typically clings to sewer root masses. The foaming agents shall be formulated such that one part of aqueous solution of the mixed material will convert into twenty parts foam. 2. The active ingredients shall not adversely affect the performance of the wastewater treatment plant when applied properly in accordance with manufacturer's recommendations. 3. Compounds containing copper and/or other known priority pollutants, as defined by the U.S. Environmental Protection Agency, shall not be allowed.

263 Chemical Root Control Engineer: Stantec Section Page 4 of 5 PART 3 EXECUTION 3.01 GENERAL A. Where sewer or manhole cleaning, grouting, or relining is specified or required, the foaming root control shall be performed a minimum of 60 days in advance of those operations, to maximize the biological decay of the root masses. B. No chemical root control agent shall be applied whenever the depth of flow in a sewer is greater than sixty percent of the pipe diameter, or if surcharging is expected within a 12- hour period after a treatment has been made. The Contractor shall reschedule that section of sewer pipe to be treated during a low groundwater period. C. If excessive accumulations of dirt, grease, or other debris preclude effective treatment of a sewer line, the Contractor shall clean the sewer pipe as specified in Section SEWER CLEANING prior to root control treatment. The Contractor shall wait at least 60 days after any cleaning work is performed on a pipeline scheduled for treatment in order to allow root tissues to recover prior to treating the sewer line INSTALLATION A. Application. Application of the chemical root control agent shall be by foaming in accordance with the best recommended practice for conditions present in the pipeline to be treated. Mixing and application procedures shall be in strict accordance with the manufacturer's instructions on the container label. 1. All materials shall be delivered to the site in undamaged, unopened containers bearing the manufacturer's original label. Mixing of the root treatment material shall be done no more than twelve hours prior to use. The water used shall be clear and free of acid, alkali, oxidizing agents, oils, or other organic material. Mixing water temperature shall be between 40 o F and 80 o F. 2. A foam discharge hose shall be inserted throughout the entire length of the sewer section to be treated. 3. To avoid injury to plant tissue that would reduce the effectiveness of the treatments, hydraulic or mechanical sewer cleaning machines shall not be used on any sewer section scheduled for treatment for a period of at least 60 days prior to the treatment. Hydraulic or mechanical sewer cleaning machines may not be used to convey the foam discharge hose through the sewer section, or to convey ropes or cables through the sewer section. 4. Acceptable methods of conveying the foam discharge hose through the sewer section are: 1) manually or mechanically shoving the foam discharge hose through the section, or 2) floating a rope through the sewer section and using the rope to pull the foam discharge hose into the section. 5. The equipment used shall discharge foam under sufficient pressure (approximately 30 psi) to assure that the entire air space above the flow in the sewer from manhole to manhole is completely filled with foam, and to assure that the foam is forced up connecting lateral sewers approximately 10 to 15 feet. Hose retrieval rates must be timed to evenly distribute the full quantity of foam throughout the entire area of treatment. The quantity of foam (see table below) shall be sufficient to completely fill the entire volume of the main sewer treated,

264 Chemical Root Control Engineer: Stantec Section Page 5 of 5 plus an additional 10% to allow for the penetration of material up lateral sewers, and for loss in manholes. Concentrate, gallons Solution, gallons Foam, gallons 2,000 4,000 6,000 6-inch pipe, LF 1,250 2,500 3,750 8-inch pipe, LF 750 1,500 2, inch pipe, LF 500 1,000 1, inch pipe, LF , inch pipe, LF Sewer service to homeowners shall not be interrupted. The Contractor must beware that excessive discharge pressure, and/or excessive quantities of material may cause foam to enter houses or travel up cleanouts onto lawns. 7. Removal of any remaining root material shall be done after sixty days, immediately prior to lining or testing and sealing of the pipeline. B. Should any chemical root control agent spill on the ground, the chemical and affected soil shall be removed and safely and legally disposed of. The area shall be restored to a condition equal to or better than before the spill. Any damage to vegetation resulting from misuse of the chemical root control agent shall be the responsibility of the Contractor. C. The Contractor shall be responsible for any and all damage to structures inside and out, vegetation, and property caused by root control chemicals. The Contractor shall be responsible for the protection of all persons, vegetation, animals, and property. D. The Contractor shall be responsible for insuring that there are no adverse effects on wastewater treatment plant processes, the quality of wastewater treatment plant effluent, or the water quality of the downstream receiving stream(s) as a result of chemical applications. The Contractor shall take all necessary steps to prevent said adverse effects at no additional cost to the Owner. E. Filling of a chemical mixing tank shall be done with an air gap or reduced-pressure- zone backflow prevention device, as approved by the Owner. The Contractor may only draw water from public water supplies at locations and using procedures approved by the Owner. F. The Contractor shall keep complete, accurate records of each day's operation.
