Demobilization This item shall include all labor, equipment, and costs associated with demobilization and clean-up of the work site to its original or better coedition. All equipment and supplies, materials, and debris related to this project will be removed from the site upon completion. The CONTRACTOR shall also reclaim any staging area or other ground disturbed during the course of the project located outside of the project area as defined by this Bid Document. Areas of disturbance will include those areas compacted as a resuh from equipment or vehicle traffic. All compacted areas will be ripped to a minirmim depth of 8" on 24" centers. All haul roads w~71 be fidly regraded and reclaimed upon completion of the project. Additional final grading shall be accomplished to reduce any cuts left from machinery or oversleep slopes within impacted areas, if needed. The CONTRACTOR shall be fully responsrble for any and all damage to property caused by his equipment or personnel The CONTRACTOR shall ensure that the job site is restored to original or better condition and that the PROJECT MANAGER accept that the work is complete. See also Section 1.0 of the "Standard Work Specifications" included in CDMG General Bid Specifications, 1996. Measurement and Payment No measurement for payment shall be made for mobilization and demobilization. Alump sum bid for mobilization and demobilization shall be reflected under Item 1 of the Bid Schedule. Payment oftwo-thirds of the hrmp sum price will be made with the first monthly progress payment after completion of the work descn'bed above for mobilization. Payment of one-third of the hunp sum price tvffi be made with the final progress payment for the work if demobilization has been completed. If the price bid for mobilization and demobilization is greater fifteen percent (15%) of the total contract price, invoices supporting the mobilization costs will be required before payment is approved. ITEM 2 - SLOPE DRAINAGE CONSTRUCTION A maximum 3: i (H: V), eight (8) foot wide drainage course will be constructed from the staked location in the field upwards to a location which will day-light on the bench. The drainage will be constructed according to the attached Drawing 1, Drainage Course Cross Section. The bottom of the drainage course will be lined with riprap. Riprap, available on-site, will consist of an evenly distributed combination of 60% minimum 4' diameter rock, 20% 2' to 3' diameter rock and 20% 12" to 18" rock The 4' diameter rock will be keyed 'into the bottom of the constructed 3:1 chaunel through excavation placement to a depth between 18" and 24". Placement will be from the lowest portions progressing upslope. The ditch depth will be 4' with a minimum 30" depth of riprap lining the channel. Side slopes to the constructed channel will be at a maximum 3:1 slope. Side slope riprap will consist of an evenly distributed combination of 75% minimum 24" diameter rock and 25% 12" to 18" diameter rock. Side slope riprap will extend up the sides of the constructed channel to a minimum 24" height. Contour furrows which aze elitninated as a resuh of drainage construction writ be reconstructed to tie into the drainage course, parallel to contour. (Note: the initial method of contour fiurow construction was by the downward blade action from a smaller dozer which was facing downslope, progressing up slope towards the bench.) The highly eroded drainage galley which exists downslope from the staked location to the slope break at the base of the grade will also be constructed to conform to Drawing 1, Drainage Course Cross Section. Material as a result of drainage course construction maybe excavated and hauled to a terrace location located to the
