2 5. Bid prices for the Base Bid will be maintained for the duration of the Base Bid regardless of fuel cost increases. However, SLID will entertain a modification in the contract prices should a significant change in fuel prices exist between the time the Base Bid was submitted and when an Additive Alternate Bid (AAB) or a portion thereof is awarded using a FDOT indexes as a reference. 6. In order to minimize costs, impacts to County and State roads, and to help expedite the project, suggested placement of fill will be allowed in areas as designated by the attached Exhibits. The contractor is not obligated to use these properties. These areas where fill can be placed are SLID owned lands, private land within SLID boundaries which is adjacent to the project, unimproved section of the Sebring Regional Airport via access through the Davis property/sebring Ranches. The contractor is to incorporate this into the bid prices and is to assume all responsibility when performing this task which may include but not limited to construction of temporary haul road(s), culvert crossings, installation best management practices for sediment and erosion control purposes, coordination with SRA & private land owners (SLID will provide contact information), restoration of lands and impacted roads, etc. Should the contractor choose alternate locations other than the ones suggested by SLID, a description of these locations must be provided in the bid submittal. The material to be deposited on Airport property and on the Sebring Developers property is to be free of organics or muck. The material must be suitable for site development and meet the classification of select or plastic soil based upon FDOT specifications. Highly plastic and/or muck material will not be allowed. The Airport reserves the right to have the contractor remove unsuitable material, at his own expense. The Airport will coordinate through CAS field representative who will oversee this effort. The Airport reserves the right to visit the stockpile site. A haul route to the Airport has been provided in the attachment and is subject to change. Limitations on all of these locations may be encountered and SLID will reasonably work with the contractor to find a suitable solution of fill placement. 7. CAS has received confirmation that the County landfill will accept all uncontaminated fill as well. The contractor shall be responsible for obtaining testing parameters from the County and costs for testing of this material. No additional compensation shall be made should the Contractor choose this option. 8. The additive alternate bid schedule for FY2017 has bid items for wetland plants to be used as directed by SLID in the event marshes are not sufficiently colonized by the anticipated native wetland vegetative species. The suggested plant species are shown below. An equal number of each species will be planted in those areas not colonized by the native wetland vegetative species.

For dewatering purposes, what is the invert of the channel bottom west of the pump station? No answer can be provided for this question. The SLID pump station will not be used as a dewatering system. Technical Specification E States: Where muck is encountered at the boundary of the site, sheeting shall be installed and left in place to preclude future damage to the installed fill by adjacent muck. Is there an anticipated area where this may be required? No specific area is made available. Procedures are to be reasonably followed where muck is encountered. It appears that Cross Sections 4 and 5 do not show the existing elevations of the perimeter ditch. Can you provide clarification?
