�A 40 O ( TECHNICAL PROVISIONS Scope of Work The project consists of providing, delivery, placement and grading of beach compatible sand to various locations along the Indian River County coastline. Bidders shall furnish all labor, materials, equipment and services necessary to complete to describe work in these specifications. + 2. Provide Fill The Contractor shall load and weigh (before and after loading) the trucks used to transport the fill from the pit to the construction site. The trucks used to transport the fill from the pit to ' the construction site. The trucks shall be weighed empty, loaded with fill (described in #3 f below) and weighed full in a location that is easily accessible and will cause no delay in the transport of the fill to the construction site. The Contractor shall have available such equipment as will be necessary to collect the fill, store the fill and to load the transport trucks t and weigh the trucks full and empty, without interruption. The scales used for weighing the trucks shall be certified by The Florida Department of Transportation 3. Fill Characteristics The construction sites are located in throughout Indian River County. Fill shall be paced seaward of the existing dune as shown in the construction drawings. The Contractor j understands and agrees the purpose of this Agreement is to renourish the beach with sand t_ which matches the existing sand on the beach within the project area in all characteristics and the Contractor shall provide fill sand material which matches the existing sand on the site in both coloration and grain size. Samples obtained from the general project areas and tested in �- the year 2000 show mean grain sizes ranging between 0.3 and 0.4 mm and percent fines averaging 1.4%. If any questions arise that the coloration of the fill sand does not match the existing sand, the County Coastal Engineer shall be the sole judge to determine if the - coloration of the fill sand is consistent with the existing sand. All fill material shall be free from construction debris, rocks, clay or other foreign matter, and shall be obtained from a source landward of the coastal construction control line or from a source authorized pursuant L. to Section 161.041, Florida State Statutes.

The fill material must also be visually similar to the sand �. on the native beaches. An analysis shall be performed by a certified independent testing laboratory and the results submitted on the Grain Size Distribution graph required in the Bid j Proposal. A moisture content analysis and modified proctor test are also required. Grain size, sorting, percent fines, composition and volume must be verified on these report. All fill furnished under this Agreement must comply with this technical specification and any 1 deviation from this specification may result in a materials breach of the Agreement. Any fill which the Contractor provides which does not meet this specification shall be removed and 4 replaced at the Contractor's expense. t' 4.
