Concrete Remedlation Services Services include the remediation of concrete sidewalk offsets in designated work areas within the City of Santa Ana. Services must remove offsets completely, from one end of the raised sidewalk joint to the . other, if applicable, leaving zero point of differential between concrete slabs. The service provided must repair each sidewalk offset without damage or visible markings to adjacent slab(s)or curb(s)and shall not cause any damage to landscaping,retaining walls,curbs,sprinkler heads,utility covers or any other objects adjacent to sidewalks. Any damages to existing infrastructure shall be repaired or replaced at the contractor's expense. 0 EquipmenVProcess Required Contractor must use a horizontal saw cutting technique that guarantees a planar surface after cutting. Contractor must guarantee specified repair slope (1:8 or 1:12 based upon requirements outlined by the City) is achieved. Contractor must guarantee that the removed offset will have a uniform appearance and texture.The finished surface shall have a coefficient of friction of at least 0.6 and show via previous testing that the technique used yields the specified coefficient of friction. The equipment used must be flush to the ground and capable of working at any angle and perform offset removal in hard-to-reach areas, around obstacles, on narrow walkways, next to fences and retaining walls or buildings. Grinding or pulverization of the concrete is NOT acceptable or allowed, causing micro-cracks or weakening the concrete panel. Contractor's offset repairs may not leave ridges or grooves that could hold water and prevent drainage of rain water or irrigation. Contractor must use a dust abatement system that limits the dust emitted from the cutting. No water-cooling is allowed which creates slurry and contaminates storm drains and causes excessive environmental impact. All clean-up services must be included in the quotation price and may not be charged at an additional rate. All clean-up will consist of full clean-up of all debris after each concrete cutting is performed. All costs incurred for disposal of waste material shall be included in unit cost and not paid for separately. • Data Collection A data collection device that records the details of the work and transmit the data electronically shall be used. The recording device must be able to record sizes of trip hazards,GPS coordinates, before and after pictures, hazard locations plotted to a map, address, and also provide this data electronically in order to integrate into a GIS system.
