Seminole Boat Ramp Restoration

City of Clearwater

Supplemental General Conditions – Special Provisions

SP-01 SUMMARY OF WORK: The City of Clearwater is seeking a qualified marine contractor for repairs to in-water components at the Seminole St. boat ramp facility. Final ramp design has been designated a contractor-activity to allow for flexibility in construction methodology. This facility services a high volume of boat launching and loading. Boats that use this facility range in size from small jon-boats to large pontoon and open fisherman. The ramp easily handles boats in excess of 35’ with combined weights of over 10 tons. The ramp contains four launching bays, each sized to handle two trailers and vessels concurrently or eight total launching ramps. Currently, the two outside ramps of the eight total are longer, approximately 56’ from the mean high water (MHW) to the toe, than the interior six ramps. The interior six ramps are approximately 46’ from MHW to the toe.

The project consists of furnishing a final design and all labor, equipment, supplies, materials, transportation, fuel, power, water, providing environmental protection, and performing all operations in connection with the Seminole St. Boat Ramp Restoration project as indicated in the attached Narratives, Plans and Specifications. All work included in the bid must be completed within the Contract Time from the date specified on the Notice to Proceed.

The project Work includes repairs and restoration of an existing boat ramp which has experienced varying levels of degradation as typical of boat ramps since original construction. The existing structure includes concrete of various strengths, thickness, reinforcement, and underlayment support. Subsurface conditions include a mixture of consolidated and unconsolidated soils and voids beneath the existing ramp. The Work will include removal of the existing ramp, dredging and grading of native soils, placement of gravel fill of various gradation, final design and installation of concrete boat ramps, and temporary relocation of floating docks along the lines and grades indicated in the Plans and Specifications. The final product will be finished, useable boat ramps suitable for the cited vessels and the exiting and final conditions outlined herein.

SP-02 PROJECT NARRATIVE & BASIS OF DESIGN: The Seminole St. Boat Ramp in downtown Clearwater, FL was originally built in 1972. Use has increased over the years. Most notably the number and size of vessels and trailers that access this facility. Heavy use and initial design have caused a number of issues, most notably, significant scour of the area at the end of the ramp and excessive cracking and undermining of the ramps and which has extended a number of feet under the ramp. The variable ramp lengths are problematic because larger boats can still access the inner, shorter ramps where the toe of the ramp is about a foot shallower. When larger boats load onto trailers, they use their engines, bringing the props close to the bottom and inducing scour.

Presently the scour hole is up to seven feet below the toe of the shorter ramps. This condition has attributed to the undermining of the ramp and concrete failure, causing hazardous conditions if left unaddressed.

This project is designed to upgrade the existing facility to better support its present uses. The project will fill the sizable scour hole at the end of the ramps with clean, coarse gravel and articulated matts to reduce the potential for scouring. The project will demolish the existing ramps and reconstruct new ramps, all at the same length (56’ from MHW) to provide similar access capacity for all eight launching bays.

Restoration of the upland portions of the project were recently complete and are to be protected.

Work below MHW will include the removal of fine, silty and clayey silt material that has migrated into low, scour holes at the end of the ramp. Dredging will be conducted by the Contractor with a suction dredge and the material shall be captured and removed for deposit at an upland landfill.

Clearwater Bay shall be protected from the migration of fine material outside the construction zone. This will be rigorously monitored. After the fine materials have been sufficiently removed, the Contractor will perform initial grading of the site to restore acceptable slopes for the ramp repairs.

Gravel of various diameters will be placed atop the initial fill prior to ramp installation. Scour protection at the toe of the ramp will be provided via installation of a articulated concrete mattress.

The existing ramps will be demolished entirely below from the point of the upland restoration to the toe. Once demolished the project will use precast concrete slabs, for the new ramp. These precast slabs will be placed in even rows, affixed to the existing upland portions of the ramp, and aligned to allow for cables to post tension the slabs. The final structure will feature slabs tensioned tight together to form a uniform ramp surface for each launching bay. Areas around the edges of the post tensions slab system will be filled with high strengthen flowable concrete fill to abut the existing bulkheads and dock structures. Areas at the end of the concrete docks will be protected by the installation of articulated mattresses abutted to the new boat ramp slabs. If needed, a water safe chemical grout may be injected through and under the slabs to assure that the slabs are on plane and there are no irregularities at the joints.

As many proprietary pre-cast systems are available for use, final design is to be proposed and completed by the selected Contractor. Pour-in-place construction may also be considered, provided the required schedules are met. The selected Contractor will provide a concept plan and schedule as part of the project mobilization and upon approval, generate a full design proposal package signed and sealed by a Professional Engineer(s), subject to the approval of the City.

The boat ramp is one of the busiest recreational launching facilities in the region, and the City desires to limit public disruption to the asset during construction. The accompanying solicitation allows for two alternate approaches, which were selected to allow flexibility in approach and schedule, recognizing that certain advantages and efficiencies may be presented by varying ramp closure sequencing. Bidders are encouraged to submit on one or both alternates.

SP-03 BID ALTERNATES: Proposers may submit on one or both of the following bid alternates:

Alternate “A” (Phased Closure): Alternate “A” is the preferred methodology of the City, as it places emphasis on reducing the full closure period at the facility and allowing for the use of half of the boat ramp while work is being conducted except during the short dredging phase 1, see below.

Work performed under Alternate “A” will include a one-time allowable closure period for all four ramps simultaneously (Phase 1) of not more than fourteen (14) consecutive calendar days for the initial site grading and fill. The allowable closure period for partial ramp closures (Phases 2 & 3) will be one-hundred (100) consecutive calendar days (EG: 50 days for west ramps closure plus 50 days for east ramps closure). The work is envisioned to include installation of pre-fabricated concrete panels, designed by a Professional Engineer and submitted for approval by the City and project Engineer. The work shall be sequenced in a manner which minimizes the period of closure for any and all ramp facilities, not to exceed a total of one-hundred fourteen (114) consecutive calendar days, and is envisioned to be carried out in the following manner:

Alternate “A” - Phase 1: The Contractor shall complete mobilization and initial grading and fill at all four ramps prior to demolition. All four ramps may be closed during Alternate “A” Phase 1 only, for a period not to exceed fourteen (14) calendar days.

Alternate “A” – Phase 2: The Contractor shall fully complete demolition, final grading, ramp installation and toe protection installation along the West Ramps 1 and 2. During Phase 2, East Ramps 3 and 4 along with Gangways 3 & 4 shall remain fully accessible and safe for routine public use and unencumbered by construction activities. Work on Phase 3 shall not commence until work under Phase 2 is complete and approved by the Owner and Engineer.

Access for routine public use of West Ramps 1 & 2 along with Gangway 2 shall be re-established prior to advancement onto Phase 3.

Alternate “A” – Phase 3: The Contractor shall fully complete demolition, final grading, ramp installation and toe protection installation along the East Ramps 3 and 4. During Phase 3, West Ramps 1 and 2 along with Gangway 2 shall remain fully accessible and safe for routine public use and unencumbered by construction activities. The total duration of partial ramp closure is not to exceed one hundred (100) consecutive calendar days for Phases 2 and 3 combined.

Period of Performance: The Contractor shall complete all work and achieve Substantial Completion under Alternate “A” within one hundred eighty (180) calendar days from Notice To Proceed.

Alternate “B” (45-Day Closure): Bids submitted under Alternate “B” will be considered by the City during selection. Work performed under Alternate “B” will include a maximum allowable closure period for all four ramps simultaneously of not more than forty-five (45) calendar days total during an allowable closure period of January 3rd, 2027 through February 15th, 2027. Work methods and sequencing shall be proposed and approved by the Owner and Engineer prior to commencement.

The work shall be sequenced in a manner which ensures the period of closure for any and all ramp facilities does not exceed the maximum allowable duration, not to exceed a total of forty-five (45) consecutive calendar days, and is envisioned to be carried out in the following manner:

Alternate “B” – Sequencing: The Contractor shall fully complete demolition, final grading, ramp installation and toe protection installation along the Ramps 1, 2, 3, and 4. Access for routine public use of all ramps and Gangways shall be available prior to the 45-day closure on January 3rd, 2027, and shall be fully restored not later than February 15th, 2027. The Contractor may mobilize and conduct the initial grading prior to the allowable ramp closure date, however cannot interfere with ramp use. This may be accomplished with a combination of a rigorous maintenance of traffic effort, with no waiting for use of a ramp and appropriate movement of contractor vessels and equipment to provide access to the ramp.

Period of Performance: The Contractor shall complete all work and achieve Substantial Completion under Alternate “B” within one hundred eighty (180) calendar days from Notice To Proceed.

SP-04 PHYSICAL DATA: The indications of physical conditions on the drawings and in the specifications are the result of site investigations by surveys and/or visual observation which are representative of conditions observed at that time.

The Contractor is advised that water quality impacts beyond limits of work shown in the plans are not authorized. The contractor shall at all times maintain a fully-enclosed floating turbidity barrier around all work activities which may generate suspended solids (turbidity) in the water column. If, at any time, turbidity plumes are observed to extend beyond or around the turbidity barrier, for any reason, including those beyond the control of the contractor, work shall be immediately suspended until such time that the source of turbidity is contained within the work limits and additional measures are placed into service to prevent reoccurrence.

In order to reduce possible impacts to water quality in the project vicinity, the Contractor will be required to “wash” stones prior to arrival of materials to the project site. The term wash is to mean stones shall be free from visible dust, debris, mud, etc. Washing is to occur prior to material delivery to the site; no washing will be allowed to occur on the Owner’s property except as approved by the Owner.

Elevated turbidity levels are not permitted and a zero (0) NTU above background standard outside of the project limits is established for the project. The Contractor may be required to demonstrate compliance with this standard. If measurements or monitoring for turbidity is determined to be necessary by the Owner, it shall be conducted in conformance with the FDEP Standard Operating Procedure FT 1600 (effective May 20, 2026), “Field Measurement of Turbidity and Total Suspended Solids”. Compliance samples are to be taken at mid-depth within twenty feet (20 ft) of the densest portion of a turbidity plume. The compliance sample is to be compared to a background sample, taken at mid-depth, 300 meters up-drift from the compliance sample, in the opposite direction of likely flow, and clearly outside the limits of any potential turbidity plume.

Fish and wildlife resources: The Contractor shall keep construction activities under surveillance, management, and control to minimize interference with, disturbance to, and damage to fish, wildlife, and plants including their habitat. The Contractor shall be responsible for the protection of threatened and endangered animal and plant species including their habitat in accordance with Federal, State, Regional, and local laws and regulations.

Any listed species that is observed in stressed condition, is killed, or is injured at the worksite shall be reported immediately to the Owner.

Manatee Protection: The Contractor shall comply with the following standard manatee protection conditions for in-water work:

All personnel associated with the project shall be instructed about the presence of manatees and manatee speed zones, and the need to avoid collisions with and injury to manatees. The permittee shall advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine Mammal Protection Act, the Endangered Species Act, and the Florida Manatee Sanctuary Act.

All vessels associated with the construction project shall operate at "Idle Speed/No Wake” at all times while in the immediate area and while in water where the draft of the vessel provides less than a four-foot clearance from the bottom. All vessels will follow routes of deep water whenever possible.

Siltation or turbidity barriers shall be made of material in which manatees cannot become entangled, shall be properly secured, and shall be regularly monitored to avoid manatee entanglement or entrapment. Barriers must not impede manatee movement.

All on-site project personnel are responsible for observing water-related activities for the presence of manatee(s). All in-water operations, including vessels, must be shutdown if a manatee(s) comes within 50 feet of the operation. Activities will not resume until the manatee(s) has moved beyond the 50-foot radius of the project operation, or until 30 minutes elapses if the manatee(s) has not reappeared within 50 feet of the operation. Animals must not be herded away or harassed into leaving.

Any collision with or injury to a manatee shall be reported immediately to the Florida Fish and Wildlife Conservation Commission (FWC) Hotline at 1-888-404-3922. Collision and/or injury should also be reported to the U.S. Fish and Wildlife Service in Jacksonville (1-904-731-3336) for north Florida or in Vero Beach (1-772-562-3909) for south Florida, and emailed to FWC at ImperiledSpecies@myFWC.com . Temporary signs concerning manatees shall be posted prior to and during all in-water project activities. All signs are to be removed by the permittee upon completion of the project.

Temporary signs that have already been approved for this use by the FWC must be used. One sign which reads Caution: Boaters must be posted.

All manatee sightings shall be reported in daily quality report submittals.

SP-11 VARIATION IN ESTIMATED QUANTITIES: Unit-priced items in this contract are estimated quantities. If the actual quantity of any unit-priced item varies more than twenty-five percent (25%) 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% or below 75% of the estimated design quantity.

If the quantity variation is such as to cause an increase in the time necessary for completion, the Contractor may request in writing, an extension of time, to be received by the Owner within 10 days from the beginning of the delay. Upon the receipt of a written request for an extension, the Owner shall ascertain the facts and make an adjustment for extending the completion date if, in the judgement of the Owner, such extension is justified.

SP-12 TEMPORARY FACILITIES: An area of the Owner’s property has been designated as a staging area for storage, access, temporary utilities, construction aids, and parking. The Contractor is responsible for providing all utilities necessary to perform their work. Alternate equipment and material staging areas may be available at the project site. Reasonable requests for additional staging will be considered by the Owner and accommodated at their sole discretion.

The Contractor shall provide and install temporary construction fencing around the entirety of the utilized staging area. All material and equipment should be stored within the fenced area when not in use. Staging and access/stockpile areas shall be maintained in clean, neat condition at all times.

It is the Contractor's responsibility to exclude the public from the staging area and the Contractor’s active work area.

The Contractor shall install and maintain protective matting atop of all concrete and pavement contained within the staging area. Matting shall be of industrial-grade, composite type, and is required for all areas within the fenced staging area that is not subject to demolition or repair as part of the work. Ground matting shall be underlaid with soft fabric that is of sufficient weight and quality to prevent scratching and marring of hardened surfaces. Plywood sheeting is not an acceptable means of matting within the staging area.

The Contractor is responsible for providing suitable dumpsters for waste containment. Waste bins should be covered to prevent windblown trash and emptied as necessary to prevent overflow of trash and debris. No on-site lavatory facilities will be available to the Contractor throughout the duration of Construction. The Contractor shall be responsible for supplying their own facilities.

Protection of existing facilities, utilities, structures, sidewalks, roadways, piers, docks, ramps, and the like, shall be the responsibility of the Contractor who shall provide adequate protection to maintain proper service. The Contractor will be responsible for the restoration of any damages caused by unpermitted, unapproved, and/or careless operation during construction. Restoration activities are subject to review and approval by the Owner and regulatory agencies. All restoration activities shall be at the expense of the Contractor and will be performed at the discretion and direction of the Owner. The Contractor will be required to compensate the Owner for any costs, fines, or other expenses incurred by the Owner related to permit violations. Compensation will be in the form of a deduction from any payment due or to become due to the Contractor.

After removal of all equipment and materials from the staging area, the Contractor shall remove temporary fencing and protective matting from the site promptly. All areas used by the Contractor must be restored to pre-construction or better conditions. This may include grading, laying topsoil and/or sod, re-paving, re-surfacing, concrete repair, and/or seeding or replacement of trees or other landscape damaged by Contractor. After removal of the Contractor’s equipment and restoration of the site is complete, the Contractor must submit to the Owner a Demobilization Site Inspection. The Demobilization Site Inspection shall consist of photographic documentation of each staging area and site access used by the Contractor. Each photograph shall be date- and time-stamped and be geographically referenced. If the Owner determines that the Contractor has caused damage to the site or surrounding structures that have not been repaired by the Contractor, the Contractor will be required to restore the site to premobilization conditions or better at the Contractor’s expense prior to final payment. Once the Contractor has submitted a Demobilization Site Inspection for a staging or storage area, the Contractor will not be allowed to return to the site with equipment unless otherwise approved by the Owner.
