The removal of alltemporary access ways, signs, temporary fencing, and temporary facilities or works and the restorationof surfaces to an equal or better than existing condition shall also be included as part of demobilization3.The contractor shall access the site using established roads and routes designated by the landowner.4.Utilitiesa.The contractor shall be solely responsible for having utilities located prior to construction activities.b.The contractor shall immediately contact the affected utility service to report any damaged ordestroyed utilities. The contractor will provide equipment or labor to aid the affected utility servicein repairing damaged or destroyed utilities at no cost to the owner.B.MACHINERY AND EQUIPMENT CLEANING REQUIREMENTS1.The CONTRACTOR will wash all earthwork equipment to remove seeds, roots, and rhizomes from theequipment prior to initial transport to the site in order to prevent the spread of noxious weeds to thesite. (This is not meant to apply to service or employee vehicles that will stay on the roadway travelingfrequently in and out of the Project area.) All earthwork equipment shall be pressure cleaned and becompletely free of soil, seeds, vegetative matter, or other debris that could contain or hold seeds priorto the initial arrival to the construction site.2.All CONTRACTOR equipment will arrive at the work site clean and weed-free. The CONTRACTOR willperiodically inspect and verify that equipment is arriving free of soil and debris capable of transportingnoxious weed seeds, roots, or rhizomes.3.Equipment will not be sprayed with herbicide chemicals as a preventative measure. Many herbicidestarget a wide range of vegetation and using herbicides in this way may harm desirable vegetation.4.The CONTRACTOR will also thoroughly clean and inspect seeding equipment prior to conductingseeding activities.C.DEWATERING AND DIVERSION CONSIDERATIONS1.Dewatering may be needed to prevent surface water and subsurface or groundwater from flowing intoexcavations and from flooding project site and surrounding area. Dewatering shall be adequate to allowproper compaction of subgrade materials.2.If dewatering is needed, the Contractor is responsible for obtaining the appropriate DEQ dewateringpermits and for providing dewatering equipment and methods as necessary for this project. Work willbe performed during low water in the East Gallatin. All costs of dewatering, including permitacquisition, measures to handle the discharge and all related work of cleanup, restoration, etc. shall beincidental to the work.3.Contractor is responsible for constructing and maintaining a diversion suitable to divert water aroundthe construction site. The diversion shall be installed to minimize impact to the water way. Thediversion shall be removed and channel restored to pre-disturbance conditions and elevations uponcompletion.D.EXCAVATION1.Excavation shall be made to the grade, dimensions and cross sections as shown on the drawings.Care shall be taken to insure that no excavation is made below grade or beyond the dimensions of theplanned excavations. In the event that excavation is made beyond the above limits, the Contractorshall replace the excavated materials and compact the replaced material.2.Salvaged trees shall be large wood pieces removed from within the project footprint that is deemedacceptable for reuse in project construction by the Engineer.3.Topsoil shall be salvaged and stockpiled separately from the underlying materials.4.Excavation above the waterline shall proceed such that excavation spoils are carried away from thewater, or otherwise collected and contained before being allowed to contact surface waters.E.GENERAL FILL1.Fill and backfill shall be an aggregate of native alluvium consisting of sorted gravels, sand, and cobblesnative to the site. Backfill shall be well-graded suitable native material free of frozen lumps, concrete,and other debris.2.Select fill shall be general excavation from within the project footprint that is deemed acceptable forreuse in project construction, including fill within the project limits, bank reconstruction, and for backfillof log jams. Select fill shall generally be free of chemical contaminants, stumps, and other deleteriousmaterials or organic material greater than 2 inches in diameter. When identified, select fill shall bestockpiled for eventual use by the contractor.3.Type and amount of material used for backfill, and the manner of placing material shall be subject toapproval by the Engineer. The Contractor shall ensure that native soils excavated on site are approvedby the Engineer before being used as backfill. The Engineer reserves the right to reject materials that,in the opinion of the Engineer, are determined to be substandard for any reason.4.Do not place backfill material when either the material or the surfaces on which it is to be placed arefrozen.F.IMPORTED 18" MINUS STONE1.Stone shall be naturally rounded in shape and will have a naturally smooth surface, such as rock thathas as its source a former stream, river, or glacial deposit.2.Stone shall meet the gradation requirements specified in the design drawings. However, theENGINEER will coordinate with the CONTRACTOR to review rock sources and mixtures and adjustgradations to achieve a desired overall gradation.3.
