(see “Fair and Open Standardized Submission Requirements and Selection Criteria” for further information) The following is a description of the professional services needed including, where appropriate, a brief description of the tasks involved: Repaupo Flood Gate Levee Reconstruction Phase II Design Services The Gloucester County Improvement Authority is seeking professional engineering and design services for Phase II of the Repaupo Creek levee system in Greenwich Township. The project consists of design, permitting and construction management services for raising approximately 4,000 linear feet of levee between the Repaupo Creek floodgate and the White Sluice Run from to approximately 11 feet in height with a 15 foot crown width in order to meet the 100 year storm event. This is a continuation of work done to a total of 900 linear feet directly to either side of the Repaupo floodgate. The project involves the production of final design plans, obtaining the necessary permits from pertinent regulatory agencies along with bidding and coordination services. Other services provided should include ROW and utilities coordination. The design should be in accordance with guidelines published by the US Army Corps of Engineers. Raising the originally levee at approximately 1,500 feet south of the floodgate structure in Logan Township and ends 3,400 feet north of the existing floodgate structure in Greenwich. Current Levee Structure The existing levee structure is composed of fill material primarily consisting of silty clay and sand and extends o approximately 12 feet below existing surface grade. The foundation is a soft organic material extending to depths that range from 25 to 49 feet below existing surface grade. Below that layer of organic material is sands and silty sands which extend to a depth of approximately 99 feet or more below the surface grade. The existing levee geometry varies throughout the project limits with in variations in height, crest width and side slope geometry. The river side slope is predominately 1H: 1V throughout most of the project with some locations between 0.5H: 1V to 1.5H: 1 V. The river side slope is armored with concrete ruble, which varies in size and is heavily vegetated from the location to the eastern end and it is unknown if concrete rubble is located along the embankment. The inland slope varies from 1H: 1V to 2H: 1V throughout the project limits. The slope is primarily heavily vegetated with some large trees near the eastern end. The crest width varies greatly throughout the project limits. The crest width along the western end is approximately 8 feet wide, while the crest widths along the eastern end vary from 20 to 30 feet. Levee Improvements Base on the USACOE levee design manual, a typical levee will need to be developed utilizing the requirements for crest width and side slopes, which provide for an adequate factor of safety and minimizes environmental impacts. A typical section calls for a minimum crest width of 15 feet and side slopes of 2H: 1V. The 15 feet will provide adequate width for maintenance and construction vehicles. The 2H: 1V provides for the minimum stability and stable slope for riprap of the embankment face. Based on the geotechnical recommendations for settlement, the proposed levee modifications should be developed utilizing a final construction grade elevation of 12, anticipating a final levee elevation of 11 post-settlement. The top and inland embankment face should be designed for construction with suitable fill material, which will provide an impermeable barrier with soil stabilization matting. The Delaware River side of the levee design will require contemplation of armoring to prevent scour and erosion of the embankment face. Scope of Work Surveying and Mapping The project will require surveys of the project site to obtain details for the final design and ROW easements required for the proposed improvements and permit applications. Survey will be required of mitigations sites will also need to be incorporated. Right of Way Acquisition Documents Determination will need to be made of private property ownership of tax parcels and easements. ROW documents will need to be provided to gain access and to construct the levee improvements. Plans depicting the surveyed conditions will need to be prepared in accordance with requirements from the NJ Department of Environmental Protection (NJDEP) for Riparian Grants, Leases and Licenses and the NJ Map Filing Law NJSA 46:23-9.8. They will need to be sufficient in detail to accompany deeds prepared for the acquisition of easements or fee simple parcel purchases and to accompany applications to the NJDEP and suitable for filing in the County Clerk’s office if required. Services outlined above need to be performed by or under the direction of a NJ licensed Professional Land Surveyor. The plans illustrating the survey results need to be prepared using AutoCAD software. Deliverables will include signed and sealed copies of the documents as required by the Tidelands Bureau, Townships, Gloucester County and the NJ Map Filing Law. Utilities Coordination will be required for relocation of the approximately 2200 feet of existing utilities in order to facilitate construction. Final Design and Construction Documents Final plans will be produced for the raising of 4000 feet of levee approximately 3 feet along the existing levee structure from approximately 1500 feet south of the floodgate structure in Logan Township and ending 3400 feet north of the floodgate structure in Greenwich Township. The 4000 feet of levee improvements excludes 900 feet of levee addressed as part of a Phase I in the project. Necessary field investigations will be completed as part of this project design scope to determine if conditions have substantially changed from previous surveys as a result of environmental factors. The alignment of the levee will need to minimize impacts to wetlands and state open water. Evaluation of the need for gabion wall to reduce impacts to wetland and state open water and armor the levee should also take place. Studies will need to be conducted to identify any areas that could be eligible for the jurisdiction of the State Historical Preservation Office. Upon completion of this study requirement, the design will need to minimize the impact to sensitive areas to avoid permitting delays. Upon receipt of necessary permits, finalization of construction documents for the levee improvements will expeditiously take place for construction contractor procurement. Final construction cost estimates and specifications will follow NJ Department of Transportation (NJDoT) standards. Up to 10 sets of final construction documents will be provided. Permitting Regulatory review of the proposed project is under the jurisdiction of the USACOE Philadelphia District and the NJ DEP’s Land Use Regulation Program (LURP). Specifications for the Joint Permitting Process (JPP) will need to be adhered to and permit application requirements by each agency. All permits required by and reports produced for regulatory agencies will need to be obtained in the most expeditious manner. These could include but are not limited to: ACOE Nationwide Permit Number 3 or Individual Permit, NJDEP Waterfront Development Permit, Tidelands Interim License and Grant, NJDEP Freshwater &/or Coastal Wetland Permit, NJDEP Historic Preservation Office Survey, Threatened and Endangered Species Habitat Analysis, Essential Fish Habitat Assessment and mitigation requirements. Preapplication meeting(s) should take place through the JPP process. Coordination meetings through the ACOE, DEP and any relevant other state and federal agencies and their divisions that have an interest will also need to take place. Progress meetings with the GCIA will also need to take place on a regular basis. Bidding Process The GCIA will advertise the project and distribute plans and specifications to any prospective bidders. After the project is advertised, the successful firm will be responsible for answering questions that may arise during the bidding phase. That firm will also assist in with the receipt of bids, with the evaluation of bid documents, including the value of the bids, insurance certificates and bonding, etc. A tabulation sheet will be prepared, which will help in evaluation of the bids. Upon determination f the lowest responsible bidder, the contractor’s credentials will be surveyed by that firm as well in order to determine the contractor’s performance on prior, similar projects. Subject to verification of the bids and the contractor’s credentials, a recommendation of award will be prepared and submitted to the authority. .
