this includes existing depths, estimated quantities to be dredged for the project, estimated quantities for over depth, and material in the side slope. A post-dredge hydrographic survey is required within 30 calendar days of the last disposal activity. Include the Corps permit number, dates of dredging commencement and completion, and actual quantities dredged (identify project depth and overdepth quantities).

Hydrographic survey procedures (positioning modes, EPS calibration, accuracy requirements, depth measurements calibration, and data reduction, adjustment, processing and plotting, etc.) shall conform to industry standards similar to, or more stringent than, those found in Army Corps of Engineers Manual EM 1110-2-1003 for Hydrographic Surveying and published November 30, 2013 (http://www.publications.usace.army.mil/USACEPublications/ EngineerManuals.aspx). The contractor is responsible for installing any survey points required and shall include that information on the drawings. If necessary, a tide board shall be installed and will remain at the facility.

Include a typical cross section(s) of the dredge footprint on the drawing. The survey shall locate the shoreline including mean higher high water (MHHW) and MLLW and show it on the cross section of the survey drawing. Locate all in-water structures outfalls, cable crossings or other man made features within or adjacent to the dredge footprint and include these structures within the hydrographic survey drawing. Drawings shall be provided in AutoCAD version 2017 file format (.dwg and .xyz) using the Civil Engineering Unit Oakland standard template (Figure A), and in Adobe Pdf.

C. Dredge Volume Calculations: Submit results of actual gross and design volume of dredged material. Cover sheet shall be signed, dated, and sealed by licensed surveyor.

D. Post-Dredge Project Report: Within 30 days after the completion of the project, the Contractor shall submit a post-dredge report to document the project’s execution.

This report will be submitted to the regulatory agencies to satisfy permit requirements. At a minimum, the report shall include a narrative of the project activities, dates when work began and finished, calculated final dredging volume based on the pre and post dredge surveys, copies of the all hydrographic surveys, maps of the dredging footprint, any noncompliance issues, required monitoring logs (DSVL), environmental permitting compliance documentation, biological reports, and the disposal location of the dredged material.

E. Standard Conditions for Use of SF-DODS: Abide by the EPA and Army Corps Standard Conditions for use of SF-DODS, which will be provided upon receipt of all environmental permits. The conditions include providing a primary tracking system for recording the ocean disposal operations, posting the disposal vessel tracking data on the internet, utilizing a third party system to generate and distribute email alerts regarding any degree of apparent dumping outside Surface Disposal Zone of SF-DODS, submitting Disposal Site Verification Logs (DSVL) on a weekly basis, and including all pertinent information in the post-dredge project report.

1.03 ARTIFICIAL OBSTRUCTIONS: The USCG anticipates debris such as, but not limited to, metal bands, pallets, pieces of broken cable, rope, hose, and broken piles. The Government has no knowledge of existing wrecks or wreckages within the dredge footprint. Debris removed from the dredge area shall be removed from the water. Explosives shall not be used under any circumstance. Disposal of debris shall be the responsibility of the Contractor and disposal shall be outside the limits of the USCG property.

1.04 QUANTITY OF MATERIAL:

A. Allowable (Paid) Overdepth Prism: The depth of the allowable overdepth (paid) prism is defined by the material below project depth and above the 2ft. allowable (paid) overdepth. To cover unavoidable inaccuracies of dredging processes, removal of material to a depth of two feet below the elevation specified and within the dredging limits will be allowed. The elevation specified for the CGC ASPEN mooring is -24ft. MLLW. The elevation specified for the SF small boat basin is -10ft. MLLW for Area A and -14ft. MLLW for Area B. Note the transition area between Area A and Area B, which requires a depths between -10ft.

MLLW to -14ft. MLLW.

B. Side Slope Prism: Dredging on the side slope is authorized for this project. Excavation areas at the toe of the slope at the berth area boundary is allowed to capture sloughed material in the side slope prism. The side slopes at the side limits of the dredge area shall be 3H:1V (horizontal:

vertical) on the. Project the side slope from the dredged bottom elevation at the limits of the dredge area line outward until it intersects the existing bottom of the adjacent waterway. Excavation areas cannot extend beyond the boundary of the berth, or deeper than the unpaid overdepth elevation. Dredging on side slopes shall follow, as closely as practicable, the lines indicated on the reference drawings.

C. Slides: In the event sliding occurs in any excavation after its completion but prior to its acceptance, the Contractor shall remove such portions of the slide at no additional cost to the Government. Particular attention shall be provided to the slope nearest to the eastern edge of the float dock.

1.05 OBSTRUCTION OF WORK AREA: Sector San Francisco homeports four coastal patrol boats, seven small boats and a buoy tender (CGC ASPEN), all which may be present during dredging operations. For this reason, the Contractor is to coordinate with the COR on scheduling activities. Once on site, and if working in proximity to the vessels, keep close communication with the Captain of the buoy tender, and the small boats to ensure appropriate safety zones are observed.

The Contractor will be required to conduct the work in such manner as to avoid obstruction to USCG operations and navigation. In case the Contractor’s plan so obstructs the navigable water as to make difficult, or endanger the passage of vessels, said plant shall be promptly moved on the approach of any vessel to such an extent as may be necessary to afford a practicable passage. Upon completion of the work, the Contractor shall promptly remove his plant, including equipment, ranges, buoys, debris boom, and other marks placed under the contract in navigable waters or onshore. The USCG will need access to the facilities during the work period and in some instances it may be an emergency. If required, the Contractor’s plant must have the ability to be maneuvered from the boat basin immediately following direction from the USCG.

Once removed, the pile shall be disposed of at an appropriate Contractor furnished offsite refuse location. The pile measures 18 inches square by 60 ft. long and weighs approximately 850 pounds.

C. Debris Plan: The solid debris management plan shall describe the methods for disposing of solid debris. The dredged material shall be passed through a grid with openings of not more than 10 inches in any dimension to prevent debris larger than 10 inches in diameter to enter the scow. The Contractor may propose another method, such as slurrying, that will similarly break up the dredge material. The Contractor shall submit a grid plan or an alternate plan for breaking up the material, including but not limited to procedures and equipment used to generate the slurry.

D. Equipment: The USCG and other authorized personnel shall be allowed access to all equipment and materials pertaining to this Contract for the purposes of monitoring and inspections.

E. Dredging Plant: Dredging shall be performed by mechanical (clamshell) dredge plant only. The use of a hydraulic dredge (hopper or pipeline) is prohibited for this project to avoid impacts to federally listed species.

F. Damage to Dredging Contractor’s Equipment: The Government is not liable for any damage to either the dredging Contractor’s equipment or the Offloading Contractor’s equipment that may have been sustained during the offloading process.

G. Interference with Navigation: Minimize interference with the use of channels and passages. The Contracting Officer will direct the shifting or moving of dredger or the interruption of dredging operations to accommodate the movement of vessels and floating equipment, if necessary.

H. Lights: Each night, between sunset and sunrise and during periods of restricted visibility, provide lights for floating plants, ranges, and markers. Also, provide lights for buoys that could endanger or obstruct navigation. If night work proposed, lights must be made available from sunset to sunrise for the observation of dredging operations. Lighting shall conform to the USCG requirements for visibility and color, and ensure lights point downward as not interfere with transient birds.

I. Ranges, Gages, and Lines: Furnish, set, and maintain ranges, buoys, and markers needed to design the work and to facilitate inspection. Establish and maintain gates in locations observable from each part of the work so that the depth may be determined. Suspend dredging when the gates or ranges cannot be seen or followed.

J. Plant: Maintain plant, scows, coamings, barges, and associated equipment to meet the requirements of the work.

K. Mobilization: Mobilization shall include all work required to prepare for contract work including preparing the Contractor’s dredging plant and equipment for shipment;

moving the plant, equipment, labor, materials, supplies and incidentals to the job site; making ready for dredging; and maintaining plant and equipment in working condition at the site during the dredging period.

L. Reaches: Dredging prior to Contractor Certification of the Government approved pre-dredge hydrographic survey is unauthorized. The project area is divided into two reaches, as presented in the figures and referred to as the CGC ASPEN mooring and the SF small boat basin. The Contractor shall not dredge in a reach without written approval from the COR. Written requests shall include a copy of the request for Reach Acceptance Survey for the previous reach if there is a previous reach.

M. Demobilization: Demobilization shall include all work required at the completion of the contract work to prepare the Contractor’s dredging plant and equipment shipment and to remove all plant, equipment, labor, unused supplies and incidentals from the job site, including cleaning up any land based staging site used in the prosecution of the work. Written permission from the COR shall be obtained prior to removing construction plant, equipment and materials from the project site.
