BID SCHEDULE

PART 1 – GENERAL

1.01 SCOPE

A. The project consists of the dredging, transportation, and disposal/beneficial reuse of approximately

2,675 cubic yards of sediment from the Indian River Channels Phase 1 Riverside Canal project area.

Actual dredge volumes will vary from estimates provided herein, as they are dependent on field conditions.

B. The County intends to award the project to the most qualified, responsible, and responsive bidder with the lowest bid.

C. If the quantity of a unit-priced item in this contract is demonstrated by the Contractor’s pre-construction hydrographic survey to be more than 25 percent of the estimated quantities as defined in the Bid Table, the Contractor may request a change order for the additional amount at the unit price specified. No additional payment will be made for material removed outside of or below the dredge template indicated in the construction drawings and once appropriate setbacks are determined. Change orders will not be considered for additional material removed unless a written request is made to the County and the Engineer in advance of removal. If the quantity variation is such as to cause an increase in the time necessary for completion, the 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 applies to the dredge quantity as measured in cubic yards.

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 with 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 significantly high.

SUMMARY OF WORK

PART 1 GENERAL

1.01 DESCRIPTION

A. Brevard County District 2 (County) is soliciting licensed and qualified marine Contractors for the maintenance dredging of Indian River Channels Phase 1 Riverside Canal in Brevard County, Florida.

The work consists of furnishing all labor, materials, equipment, and performing all tasks necessary for the excavation, handling, and disposal/reuse of accumulated sediments within the project area.

B. The following general information is based on initial hydrographic surveys and permitting conditions. The width of the Indian River Channels Phase 1 Riverside Canal varies. The width of the canal is bounded by a residential shoreline. The length of the canal is approximately 480 linear feet.

The design dredge template elevation is -5.5 feet Mean Low Water (MLW) datum, with no over-dredge. The dredge template design accommodates setbacks from mangroves.

C. All dredging activities are to be performed using mechanical means. A temporary staging area is indicated in the construction drawings. Only designated areas shown on construction drawings, may be used for offloading and temporary handling of dredged material. The Contractor shall be responsible for restoring the designated dredged material handling facility back to its original condition as documented in pre-construction surveys and photographic documentation. This includes the removal of all temporary structures such as timber mats, fencing, and erosion control devices.

D. The intent of the project is to remove accumulated sediments to the authorized design dredge depth along the length of the Indian River Channels Phase 1 Riverside Canal, without impacting adjacent natural resources or structures. Overdredge is not authorized by regulatory agencies for this project.

E. It is estimated that approximately 2,675 cubic yards of sediment could be removed from the project area. Actual quantities will be confirmed by detailed hydrographic surveys, performed by the

Contractor and approved by the County, prior to dredging.

F. Underground utilities and improvements were not located as part of this survey. It will be the

Contractor’s responsibility to coordinate these locations prior to construction.

H. The Contractor is solely responsible for all construction means, methods, techniques, and procedures including construction monitoring, permit compliance, and the sequence of the work.

I. The Contractor shall be responsible for the design, installation, and maintenance of other site elements necessary to support the dewatering and hauling of dredge material.

J. Regulatory permits require turbidity monitoring to be conducted prior to, and for the duration of the project.

K. The Contractor must comply with the applicable Florida Fish and Wildlife Conservation Commission

(FWC) Standard Manatee Conditions for In-Water Work.

SECTION 01 11 00 2 July 15, 2025
