ST. CHARLES COUNTY MOWING PROJECTS

2026 CONTRACT PROVISIONS

A. NON-PREVAILING WAGES

1.0 This contract involves only maintenance of the state highway system with no construction work being performed. Therefore, under Missouri Statutes this contract does not require payment of the prevailing hourly rate of wages for each craft or type of worker required to execute the contract.

B. CONTRACT TERM AND EXTENSION

1.0 The contract term shall be for the period listed in the project details. Any work ordered prior to the termination date shall be completed in accordance with the contract.

2.0 The contract may be extended under the original contract specifications and contract prices for up to two

(2) additional contract terms. If the Commission desires to extend the contract, the contractor will be given written notification of the offer to extend no later than November 15 of the current contract year. The contractor shall provide written notification of acceptance or rejection of the contract extension offer no later than December 15 of the current contract year. The extended contract term shall be for the period listed in the project details.

3.0 In the event that MHTC exercises its options to renew the contract for two (2) additional one-year periods pursuant to the applicable provisions outlined in this document, the Bidder shall provide below the maximum percentage of increase or minimum percentages of decrease for each renewal period. The Bidder is cautioned that the percentages shall be computed against the ORIGINAL contract prices during renewal periods.

Furthermore, the Bidder is advised that the MHTC does not automatically grant increases at the time of renewing the contract and that if an increase is requested, documentation of need must be provided at the time of renewal.

4.0 If the contract is extended, the contractor shall furnish satisfactory evidence of continued bond and insurance coverage for the extended contract term.

C. CONTRACT LIMITS

1.0 Contract Limits. The contract limits are shown on the included displays.

2.0 On-Site Review. It shall be conclusively presumed that all bidders have made an on-site review of the contract limits and all bidders have a clear understanding of the areas included in this contract and the scope of work required.

3.0 Contract Limit Changes. If the engineer determines that it is necessary to make an addition or deletion to the contract limits, the change will be handled in accordance with Section D of these provisions.

D. CHANGES IN THE WORK

1.0 When necessary to satisfactorily complete the project, the Missouri Department of Transportation (MoDOT) reserves the right to change quantities or make other changes for which there are no provisions included in the contract.

2.0 If the work does not involve a significant change in the quantity (either up or down) of an established contract item, then the contractor shall complete the work as necessary, and payment will be made at the established contract unit prices.

3.0 A significant change is defined as an increase in excess of 125% or decrease below 75% of the original contract quantity on a major item of work. A major item of work is defined as any contract item with an original value in excess of 10% of the original contract amount.

4.0 If the work involves a significant change in the quantity of a major item, then an equitable adjustment may be made to that item’s unit price. Either MoDOT or the contractor may request that such an adjustment be made, and the contractor shall furnish such information needed to establish the equitable price adjustment.

Such adjustment will be determined based on the contractor's actual costs to perform the work, excluding any anticipated profits from work not performed. This determination will be consistent with the contractor's other proven costs to perform the contract work, as shown in the contractor's bid computations and project cost records.

5.0 If the change involves an item for which no price is established in the contract, then an equitable adjustment will be agreed to by both MoDOT and the contractor prior to performance of the work. Such adjustment will be determined based on the contractor's actual costs to perform the work. If a basis cannot be agreed upon, then an adjustment will be made in such amount as MoDOT may determine to be fair and equitable.

E. CONSTRUCTION PROJECTS WITHIN THE PROJECT LIMITS

1.0 The Contractor is advised that there may be construction projects in progress during the term of the mowing contract. When construction activities do not impact or restrict access to mowable areas, the mowing contractor shall mow those areas per the project plans and specifications.

2.0 In the event that construction activities restrict access or do not allow the contractor to mow all of the areas detailed on the plans, the contractor shall skip those areas during the mowing cycle. Deductions in pay will be made (if applicable) per section D of the contract.

3.0 Some areas currently under construction may be shown on the plans. As MoDOT accepts the newly constructed areas for maintenance, the contractor may be asked to mow these additional areas. If the contractor agrees to add these areas to the contract, a change order or supplemental contract will be offered to the contractor for this work.

F. MOWING, TRIMMING OR SPRAYING, AND LITTER REMOVAL CYCLES

1.0 A mowing cycle is defined as all of the mowing, trimming, spraying, and other work indicated on the Mowing Plans. A litter removal cycle is defined as the removal of all of the litter in the entire mowing, spraying, and trimming area as indicated on the Mowing Plans. MoDOT will determine the total number of mowing cycles and litter removal cycles to be performed during each term of the contract. A mowing cycle and/or litter removal cycle is considered complete when all mowing, trimming, spraying, and litter removal are complete as defined in the Mowing Plans.

2.0 MoDOT will determine when to begin each mowing cycle. MoDOT may adjust the mowing cycles based on turf conditions, weather conditions, amount of litter, and/or other requirements.

3.0 The number of cycles for the contract is as shown in Exhibit A. One of the cycles will be a full mowing cycle. Additional mowing, trimming or spraying, and litter removal cycle(s) may be requested by the engineer.

One week mobilization will be given for each cycle.

4.0 MoDOT reserves the right to add up to one additional mowing cycle with litter pick-up and/or one litter pick-up only cycle beyond that shown in Appendix A. This is reserved for situations where a city/municipality provides additional funding to MoDOT for mowing and/or litter pick-up cycles beyond what is already specified.

This will only be done when there is reasonable time to plan. Acreage for mowing and/or litter pick-up cycles will not exceed the total acreage for a Regular Mowing Cycle and/or the total acreage for a Litter Removal Cycle as shown in Appendix A.

G. NOTICE TO PROCEED AND CONTRACT TIME FOR COMPLETION OF WORK

1.0 MoDOT will issue a notice to proceed for each mowing and litter removal cycle which will stipulate the date the contractor is expected to begin work. The notice to proceed will be issued at least five (5) calendar days before the stipulated date to start work for each cycle.

2.0 The contractor shall complete all work required for each mowing and litter removal cycle through the entire contract limits within the specified number of working days after the notice to proceed date. If the contractor elects to begin work prior to the notice to proceed date, the working day count will begin on the day the contractor's operations begin.

3.0 A working day will be defined as any day when, in the judgment of the engineer, soil and weather conditions would permit the major operation of the project for six hours or more, unless other unavoidable conditions prevent the contractor's operations. If conditions require the contractor to stop work in less than six hours, the day will not be counted as a working day. Saturdays, Sundays, and holidays established by law will not be counted as working days. The engineer may make allowance for working days lost due to causes justifying their elimination from the count of working days. No allowance will be made for delay or suspension of the prosecution of the work due to fault of the contractor.

4.0 The number of working days will be as specified in the project details.

5.0 After notice to proceed is given, the Contractor shall advise the Engineer when the anticipated start day is for each mowing cycle to allow for MoDOT to coordinate with other construction and maintenance activities in the general mowing area.

H. LIQUIDATED DAMAGES

1.0 If each mowing and litter removal cycle is not completed within the specified working days, MoDOT and the public will sustain damages because of such delay, the exact extent of which would be difficult to ascertain. Therefore, in order to liquidate such damages in advance it is agreed that the contractor will be charged with such liquidated damages in an amount as listed below that each mowing and litter removal cycle is not complete.

a. In the event the contractor fails to provide mowing, trimming or spraying, and litter removal in accordance with the contractual requirements specified herein, the contractor shall be assessed liquidated damages in the amount of $ 250.00 per day for each calendar day the contractor is delinquent in completing the work beyond the designated cycle completion date.

b. The contractor shall further agree and understand that such liquidated damages shall either be deducted from the total amount due the contractor or paid by the contractor as a direct payment to MoDOT, at the sole discretion of MoDOT.

c. The contractor shall agree and understand that the liquidated damages described herein shall not be construed as a penalty.

d. The contractor shall agree and understand that all assessments of liquated damages shall be within the discretion of MoDOT and shall be in addition to, not in lieu of, the rights of MoDOT to pursue other appropriate remedies.

I. NON-PERFORMANCE PAY DEDUCTIONS

1.0 In the event the contractor fails to provide mowing in accordance with the contractual requirements and public nuisance and safety concerns are generated, MoDOT may elect to self- perform or hire a contractor on an emergency basis to address these issues. The acreage mowed by MoDOT will be measured and rounded up to the nearest one quarter of an acre. This acreage will be removed from the contractors pay estimate. Additionally, a pay deduction will be assessed at the same per acre contract price to compensate the owner for mowing expenses. All liquidated damages will remain in force and charged according to the terms in section G.1.0 of the contract.

2.0 Pay deductions for non-performance when assessed, shall either be deducted from the total amount due to the contractor or paid by the contractor as a direct payment to MoDOT at the sole discretion of MoDOT.

J. WORK PLAN AND SCHEDULE FOR ACCOMPLISHING WORK

1.0 Prior to starting the work, the contractor shall provide a proposed work plan and typical schedule for accomplishing the work. The work plan shall include a written list of equipment, number of personnel with their assigned work, and a typical schedule that the contractor intends to use in executing the work.

2.0 The work plan will be reviewed by the engineer to determine in general if adequate personnel and equipment appear to be available to complete the work within the required number of work days. If the engineer determines the work plan is inadequate, the engineer and contractor shall meet for a joint review of the plan to correct and adjust the plan and schedule as necessary. A revised work plan and schedule shall be provided by the contractor prior to commencing the work.

3.0 If the contractor has more than one Commission contract for roadside mowing, the priority of the work will be jointly determined by the engineer and the contractor. The priorities of the work plan will be determined by the needs of the Commission and not the contractor's convenience of work location.

4.0 The contractor shall determine the most feasible work plan and schedule consistent with the requirements of the contract. The engineer's approval of the contractor's work plan is not intended to be acknowledgment or representation that it is reasonable or will accomplish the work within a particular time or at a particular cost.

5.0 No direct payment will be made for furnishing the work plan or revisions.

K. ROADSIDE MOWING

1.0 Description. This work shall consist of mowing grassed or vegetated roadside areas including areas that may require the use of specialized equipment and hand trimming around fixed objects. Routinely mowed areas include, but are not limited to shoulders, front and back slopes, roadside ditch bottoms, raised median islands and various width utility strips. The limit of areas to be mowed next to travel ways shall begin at the contiguous line between the shoulder and grassy area. Hand mowing and trimming will be required to perform the specified work in areas that are inaccessible to mechanized equipment. Vegetation to be mowed shall consist of planted or naturally occurring grasses, weeds, and other vegetation, both herbaceous and woody.

Unless otherwise approved by the engineer, all non-cultivated woody vegetation shall be cut one-half inch or less above the vegetation’s surrounding ground level. All brush, tree limbs or other loose herbaceous and woody vegetation lying on the ground in the mowing area shall be picked up and disposed of and not mowed or cut around. Vegetation that is excluded includes landscaped ornamental plantings. MoDOT has entered into the CCAA, Nationwide Candidate Conservation Agreement with Assurances, with The U.S. Fish and Wildlife Service to establish pollinator habitats along MoDOT right of ways. These locations have not been established at this time. In the event that, one or more, of these pollinator habitats be located within this contract, MoDOT will determine if these locations will be removed from this contract to be maintained by MoDOT.

2.0 Work Schedule.

2.1 All work shall be performed during daylight hours.

2.2 At least two (2) calendar days prior to beginning each mowing cycle, the contractor shall notify the engineer by phone, email or entry on a MoDOT dedicated SharePoint site of the proposed start date, working hours, starting location, and the direction in which mowing operations will proceed.

Trimming or otherwise cutting of all vegetation shall be done along rock blankets and next to sound walls so as to provide a uniform look with the adjacent mowed area.

Trimming may be performed either concurrently with the mechanized mowing operations or following the completion of mowing.

4.4 Actions by the contractor that result in damage to turf, trees, curbs, sidewalks, pavement, signs, structures, mail boxes, delineators, landscaping, or other appurtenances shall be repaired or replaced to the satisfaction of the engineer at the contractors expense. All repairs shall be done before pulling off the job. All metal delineators located just off the shoulders shall be straightened to their originally installed position. Ruts, tire tracks, and other disturbed areas caused by the contractor shall be filled with approved topsoil and re-seeded as directed by the engineer at the contractor’s expense.

5.0 Proposals for Use of Herbicide. The contractor may propose to use herbicide treatment of mowed or trimmed areas to minimize or eliminate mowing or mechanical trimming. All proposals shall be submitted to the engineer for consideration at least 2 weeks prior to the use of any herbicide. The proposal shall contain all information required for a full evaluation by MoDOT. Such information shall include the type of herbicide, labeling details, contractor certification/licensing for application of the herbicide, health and safety plane, etc.

No herbicide shall be used without approval by MoDOT.

6.0 Method of Measurement and Basis of Payment. Final measurement of mowed and trimmed areas will not be made except for authorized changes, or where appreciable errors are found in the contract quantity.

Where required, measurement of mowed and trimmed areas will be made to the nearest acre. The revision or correction will be computed and added to or deducted from the contract quantity.

6.1 An appreciable error is defined as an error resulting in a change in quantity of 10 percent from the original contract quantity of an item or an error resulting in a monetary change of at least $5,000 from an original contract item.

6.2 Payment will be made for contract quantities except when authorized changes are made to contract quantities or if an appreciable error is found in contract quantities. Trimming and spraying will be considered incidental to the contract and no additional payment will be made to the contractor for spaying or trimming.

6.3 Payment will be considered full compensation for all labor, equipment, and material necessary to perform the described work.

L. LITTER REMOVAL AND DISPOSAL – CONTRACTOR PERFORMED

1.0 The contractor shall perform all litter removal and disposal from the mowing areas. MoDOT forces will not perform litter removal operations during the term of this contract within mowing areas. However, between the contractor’s mowing or litter removal cycles MoDOT may elect to perform minor litter removal work in response to aesthetic concerns. MoDOT generally performs a statewide litter removal campaign during March of each year along many highly traveled state roadways. MoDOT may perform some litter removal work during March along the roadways included in this contract, however it will not be comprehensive litter removal of the entire mowed areas.

2.0 A litter removal cycle shall be performed prior to each mowing cycle. The contract allows for additional litter removal cycles that will be performed independently of a mowing cycle (No mowing cycle will follow the litter removal cycle). Refer to Appendix A for the specified number of litter cycles for the contract. These additional litter removal cycles will be performed as specified by the engineer. The notice to proceed for the additional litter removal cycles will be issued at least five (5) calendar days before the stipulated date to start work for each cycle.

3.0 The contractor shall remove all litter greater than approximately ¼ square foot. The contractor shall also remove any other items, regardless of size, which will become scattered and unsightly when mowed. The contractor shall properly dispose of all collected litter at the end of each working day. Any additional litter accumulated after the initial litter removal operation but prior to the contractors mowing operation, or any litter scattered by the contractor's mowing operations shall be immediately removed and disposed of properly at the contractors expense.

4.0 The contractor shall provide the quantity of trash collected on each litter cycle when submitting the invoice. The quantity reported will be agreed upon by the contractor and the engineer prior to the mowing season. Examples of acceptable measurements are bags, truck loads (if type of truck is described), tons, or cubic yards.

5.0 The contractor shall inform the engineer of any unusual items encountered along the roadway, such as dead animals and hazardous wastes. These items will be handled by MoDOT forces unless otherwise directed by the engineer. Whole discarded tires shall be picked-up by the contractor and taken to a MoDOT facility designated by the engineer. MoDOT will dispose of tires picked-up by the contractor.

6.0 Method of Measurement and Basis of Payment. Litter removal areas shall be presumed by the Commission and the Contractor to be equal to the FINAL MOWING area, including any area where spraying or trimming is required (rock blanket, rock bluffs, along fences & guardrail, etc). Final measurement will not be made except for authorized changes, or where appreciable errors are found in the contract quantity. Where required, measurement of litter removal areas will be made to the nearest acre. The revision or correction will be computed and added to or deducted from the contract quantity.

6.1 An appreciable error is defined as an error resulting in a change in quantity of 10 percent from the original contract quantity of an item or an error resulting in a monetary change of at least $5,000 from an original contract item.

6.2 Payment will be made for contract quantities except when authorized changes are made to contract quantities or if an appreciable error is found in contract quantities.

6.3 Payment will be considered full compensation for all labor, equipment, and material necessary to perform the described work.
