In the event that damage is caused by the CONTRACTOR, the CONTRACTOR shall restore all damage to sidewalks, roads, parking lots, coastal structures, dune vegetation, or any other structure or natural feature to pre-construction conditions or better. The CONTRACTOR will not receive final payment until all damage is restored to the satisfaction of the COUNTY, as stated in these Specifications. All damage will be repaired at the CONTRACTOR’s expense.

14.3. Staging Area. Upland staging areas are limited to the construction access and staging areas shown in the Plans. Select additional public parking spots for operations may be made available to the CONTRACTOR if requested in writing and approved by the COUNTY and Cities. Beach staging areas are limited to the project fill template and alongshore limits shown in the Plans. The CONTRACTOR shall cordon off and/or fence the staging areas to keep the public away from equipment. The staging areas must be restored to the pre-construction condition upon project completion at the cost of the CONTRACTOR. If additional staging or queuing areas are needed, they shall be procured by, and at the expense of, the CONTRACTOR, and with the approval of the COUNTY.

14.4. Work Area. The work area limits available to the CONTRACTOR for accomplishing the Work are shown in the Plans. Construction access to the beach is shown in the Plans, and as stated in these Specifications. The CONTRACTOR shall cordon off and/or fence the active fill placement areas to keep public away from equipment. An active fill placement area shall not exceed 500 ft. alongshore without coordination with, and approval by, the COUNTY.

14.5. Pads, Ramps, and On Beach Accessways. Fill may be required to build out staging area pads, ramps or roadways to establish access to the construction area. Based upon the pre-placement survey conditions, the COUNTY and ENGINEER may allocate material for these purposes. The CONTRACTOR shall endeavor to maintain this fill within the project limits and all fill must be graded into the construction templates prior to substantial completion of the project.

14.5.1. Temporary Sand Ramps. The South Naples project area consist of multiple deteriorated timber and concrete groins that span approximately from the upper berm into the water in the cross-shore direction. There are gaps in the groins on the dry sandy beach that may provide enough access for ORT’s to traverse the project area. If the CONTRACTOR determines that the ORT’s cannot fit through the gaps in the groins, they may construct temporary sand ramps for the ORT’s to transport fill over the groins.

14.6. Exclusion of Public. The CONTRACTOR shall accomplish the Work in such a manner so as to minimize disruption to road traffic and the use of the beach. It is the CONTRACTOR’s responsibility to exclude the public for safety purposes from the construction access, staging area, and work areas in the immediate vicinity of the active work, transport operations, or any other area that may be dangerous to the public using a temporary fence and/or appropriate signage. The CONTRACTOR shall minimize the areas closed to the public to what is required to safely conduct the Work.

14.7. Substantial Completion. At substantial completion, off-road trucks (ORTs) and other heavy machinery shall be removed from the beach and the CONTRACTOR’s staging areas are to be consolidated to allow for the construction access points to be opened for joint construction and public use.

15. USE OF COMPLETED PORTIONS

The COUNTY shall have the right to take possession of, and use, any completed or partially completed portions of the Work, prior to the completion of the entire Work. Such taking possession and use shall not be deemed an acceptance of any Work not completed in accordance with the contract documents.

16. CHANGES AND EXTRAS

16.1. Changes in the Work. The COUNTY shall have the right, within the general scope of the work and without notice to any surety or sureties of the CONTRACTOR, to make changes in the Work, including, but not limited to, changes in the Plans and Specifications pertaining to beach width, beach elevation, fill volume, beach length, environmental protection, contract time, contract price, in or to the method or manner of performance of the work, in or to equipment, materials, service or site, in or to the mode or manner of payment for the work, or directing a change in the rate of performance of the work. All changes shall, except in the case of emergencies endangering the safety of personnel or property, be made by modification of the contract documents or by written change order duly executed by the COUNTY, ENGINEER, and CONTRACTOR. Work necessary in connection with emergency changes in the Work shall be strictly limited to the minimum necessary to alleviate the immediate emergency; Work beyond such minimum shall be undertaken only pursuant to a properly issued change order received from the COUNTY.

The CONTRACTOR shall promptly comply with any and all written change orders issued by the COUNTY, notwithstanding any disputes. No such change order shall be deemed to invalidate the contract.

16.2. No Adjustment of Unit Price. The quantity of material to be placed on the beach is based on beach surveys/technical studies conducted prior to the construction of the project. It is almost a certainty that the forces of wind and waves have altered the beach since development of the estimated fill quantity for the project. No adjustment shall be made in any unit price of the contract for changes ordered by the COUNTY that cause an increase or decrease less than or equal to twenty percent (20%) in the amount of the Work, or by the estimated quantities provided in the contract documents of fill material that is to be placed within fill templates. It is further provided that no adjustments shall be made in the contract price or time of performance for either lump sum or unit price work if the change is expressly or reasonably implied by the Plans and Specifications or is incidental thereto, or if the Work becomes more difficult than the bid price and contract documents would reflect, or if CONTRACTOR failed to protest, negotiate, comment, or otherwise call to the COUNTY's attention, in writing, any omissions, ambiguities, or conflicts in the contract documents that the CONTRACTOR could have discovered prior to the submission of their bid or execution of the contract. An equitable adjustment may be made in the Contract Price for Unit Price Contracts if changes ordered by the COUNTY cause the applicable quantity set forth in the Contract Documents to be decreased by more than twenty percent (20%). Such adjustments may be made only for that portion of work that is less than eighty percent (80%) of the estimated quantity and shall be supported by data provided by the CONTRACTOR to the COUNTY, which demonstrate justification for the adjustment in Unit Price.

17. SAFETY

The following plans will be submitted to the ENGINEER and COUNTY for information purposes only. Submission of the plans does not constitute an endorsement on the part of the COUNTY or ENGINEER that the CONTRACTOR’s procedures are safe or meet applicable standards. Safety is the CONTRACTOR’s sole responsibility. All costs associated with complying with these safety conditions shall be included in the CONTRACTOR’s bid.
