BID SCHEDULE

PART 1: GENERAL

1.01 BASIS OF BIDS

A. Lump Sum and Unit Price Schedule

This Contract will be awarded based on the total cost of the bid schedule below. The base project consists of the dredging, placement in the designated DMMA, dewatering, and removal, transportation and disposal of approximately 182,972 cubic yards of sediment from the Eau Gallie Muck Removal Project Area 1A. The project includes bid alternates to dredge additional volumes within Pay Section Z to deeper elevations. The Alternate Bid 1 will be dredged to contour or the -16.5 feet NAVD88, which equates to approximately 42,007 CY of additional muck. Alternate Bid 2 will dredge Pay Section Z to contour or an elevation of -18 feet NAVD88 equating to approximately 34,940 CY of additional muck to be dredged from Pay Section Z. Finally, Alternate Bid 3 will dredge Pay Section Z to -21 feet NAVD88, which equates to approximately 31, 835 CY of additional muck. The project will be awarded based on the lowest responsive total bid amount including all alternate pay sections.

1.02 SCOPE

A. The project consists of the hydraulic dredging, dewatering, and beneficial reuse/disposal of approximately 182,972 CY of muck sediment from the Eau Gallie Muck Removal Project Area 1A. Due to the variability experienced in the actual muck volume in each pay section, it is expected that line-item amounts in the CONTRACTOR's Schedule of Values may be adjusted as needed per Section 01- 20-00 Measurement and Payment for each pay section, however the total project cost of the contract shall not be increased unless authorized by COUNTY through a future change order.

B. If the lowest total bid exceeds the available construction funds, the COUNTY may elect, at their sole discretion, to remove certain Pay Sections to bring the total costs within the available funds. Pay Section Z has been broken out in the bid pricing form to facilitate removal of certain sections if needed. If certain sections are removed from the project in order to meet the anticipated project budget, there will be no adjustments to the fixed and unit-based prices for the remaining sections and bid items.

C. If the actual quantity of the unit-priced dredge quantities and final transportation and disposal items vary by more than 25 percent above or below the estimated quantity, an equitable adjustment in the contract price shall be made upon demand of either party. The equitable adjustment shall be based upon any increase or decrease in costs due solely to the variation above 125 percent or below 75 percent of the estimated quantity. If the quantity variation is such as to cause an increase in the time necessary for completion, CONTRACTOR may request, in writing with the demand, an extension of time consistent with associated quantity variation. This variation in estimated quantity (VEQ) clause does not apply to all bid items, it only

BID NO. B-6-25-24 00 41 00-2 Brevard County applies to bid items which specifically indicate eligibility under this clause in Section 01 20 00.

D. This bid shall be for a complete project and bid item prices shall include all components necessary for successful completion of the work as designed and specified.

E. This Contract is solicited with bid items. Any bid price for items indicated above which are considered unbalanced in the opinion of the COUNTY may be rejected.

An unbalanced bid is one in which the cost for one or more bid items is considered significantly low and one or more bid items is considered significantly high.

1.02 WORK COVERED BY CONTRACT DOCUMENTS

A. DESCRIPTION

The COUNTY is soliciting licensed and qualified marine contractors to excavate, dewater, and dispose of approximately 182,972 cubic yards of muck from approximately 86 acres of the Eau Gallie Area A1/NE Muck Removal Project as described herein and depicted by the permitted lines and grades shown in the Drawings. Furthermore, there are three alternate bid items for the dredging of additional material within the dredge template. Bid Alternate 1 shall include the additional dredging of 42,007 CY to contour or a design elevation of -16.5 FT NAVD88 within Pay Section Z. Bid Alternate 2 shall include the additional dredging (not including Bid Alternate 1 volume) of 34,940 CY to a design elevation of -18 FT NAVD88 within Pay Section Z, and Bid Alternate 3 shall include the remaining additional dredging volume of 31,835 CY to a design elevation of -21 feet NAVD 88.

The Florida Inland Navigation District (FIND) property (Dredge Material Management Area) DMMA BV-52 along US Highway 1 has been made available for use as a temporary dewatering site, if desired by the contractor (CONTRACTOR). The COUNTY will provide the CONTRACTOR use of the property following approval of a signed and sealed dewatering plan proposed for use in the project. The dewatering plan is required as part of this bid submittal and will be required to adhere to the requirements found in the FIND lease agreement with the COUNTY. Note that the FIND Lease references a June 1994 Management Plan that has been replaced with the FIND Long-Range Dredge Material Management Plan Update (January 2021). This report can be found in Attachment D. Use of that property will be limited to construction and operation of a dewatering system intended for dewatering of the muck material dredged from the dredge area, and loading of dried material for transport of dredge material to final offsite disposal area. No burning or unauthorized land clearing will be allowed on this property at any time. Trees cannot be removed outside of the restoration limits unless approved by FIND. All dredge material, after dewatering per Section 35-24-00, must be transported to an upland disposal area selected by the CONTRACTOR, and approved by the COUNTY and the ENGINEER prior to use. Use of upland disposal area shall be in accordance with all local, state, and federal regulations.

The CONTRACTOR shall be responsible for the design and construction of the dewatering system and all associated elements needed for successful dewatering as described herein and depicted in the Drawings. The CONTRACTOR shall also be responsible for the design, installation, and maintenance of other site elements, such as construction of internal

BID NO. B-6-25-24 01 11 00-2 Brevard County baffles, polymer injection systems, etc. necessary to support the dewatering and hauling of dredge material. Upon completion of dredging, dewatering, and disposal of the muck material, the CONTRACTOR shall restore the dewatering facility and associated elements as depicted in the Drawings and FIND Lease requirements.

Geotechnical investigations of both the dewatering system site and the muck material have been conducted and the results of these investigations and analyses can be found in Attachment D.

B. Location

The dredge area is located on the east coast of Florida in Brevard County, Florida, located north of the County Road 518 (Eau Gallie Causeway), at approximate location 28° 8'8.75"N, 80°36'48.33"W.
