1. Grading: ▪ Water, grade, and compact roadways within RIDs, as well as supplementing and applying magnesium chloride and the County standard crushed aggregate surfacing material on roadways within RIDs as directed by County representatives. RIDs are located throughout the greater Helena Valley and it is strongly recommended that each contractor visit unfamiliar districts prior to providing proposals. ▪ Individual project scopes will be dependent on funding availability. ▪ Work is to be completed in accordance with Typical Section One in the Lewis and Clark County Public Works Manual, where applicable. 2. Watering: ▪ Contractor shall supply means necessary to achieve proper moisture content in assisting with the material compaction and longevity of surface material. ▪ Water shall be distributed prior to, during, and after the grading process. Country will assist Contractor as needed to identify locations for water retrieval. 3. Compaction: ▪ Compaction of material shall commence once the shoulders and crown are formed in the grading process and continue until a desired compaction is achieved and suitable for the longevity of the surface material. ▪ Use of static/vibratory roller or tow behind walk and roll is acceptable.
