Through this Request for Proposals, the Gloucester County Improvement Authority (GCIA), on behalf of the South Jersey Port Corporation (SJPC) seeks to engage a consultant for the term from the date the successful consultant is issued a notice to proceed letter until completion of the work on or before December 31, 2010. This contract will be awarded through a fair and open process pursuant to N.J.S.A.. 19:44A-20.4 et seq. The Consultant’s Standard Requirements of Technical Proposal (items A thru M) and Cost Proposal must be received and will be publicly opened and read aloud on July 29, 2010 at 11:00 A.M. at the GCIA administrative office located at 109 Budd Boulevard, Woodbury, New Jersey. Each consultant is advised that compliance with the “Fair and Open Standardized Submission Requirements and Selection Criteria” is required. Incomplete proposals will be rejected from further consideration. The “Fair and Open Standardized Submission Requirements and Selection Criteria” must be obtained by contacting Danae Ciociola or Megan Kerr of the GCIA at 856-848-4002. The following is a description of the professional services needed including, where appropriate, a brief description of the tasks involved: Scope of Services – Technical Proposal Introduction Geotechnical work for the Paulsboro Marine Terminal Project shall include review of existing information and geologic maps of the site, conducting a field investigation, coordinating regulatory compliant laboratory testing and preparation of a geotechnical data report for the proposed project. The project site is located in the city of Paulsboro, New Jersey, at a latitude and longitude of approximately 39.85, and -75.24 degrees, respectively. The information collected will be used to locate facilities and structures, select appropriate foundation types, and for the final design of the facilities and structures. The draft preliminary pier berthing facility drawings are provided in Attachment A and Attachment B to this scope of work. The drawing titled, ‘Existing Structure’ indicates the location of the required borings within the existing conditions whereas the drawing titled, ‘Proposed Locations’ indicates the location of the required borings within the potential post-construction terminal configuration. The work described herein will be under the direction of the GCIA’s final design consultant - CH2M HILL. CH2M HILL reserves the right to alter the geotechnical site investigation plan, including but not limited to, the location, amount, or depth of borings and test pits, amount and type of testing, and all other aspects of the work outlined herein. Field Investigation Explorations will consist of both waterside and landside borings. Waterside borings include borings performed over water and/or at the location of the proposed berthing facilities. Landside borings include borings associated with facilities located along the shoreline of the Marine Terminal. The waterside borings shall be completed first, to be followed by the landside borings, although the landside borings can be conducted concurrent with the waterside borings. Waterside borings are anticipated to be from a barge; however, the Consultant shall confirm this assumption in the Technical Proposal and prior to mobilizing for the field investigation.

Site Environmental Conditions The site was developed in the 1920’s and has been used for the storage and distribution of refined petroleum products and specialty chemicals. Historically, materials stored and distributed at this property include, but are not limited to, gasoline, fuel oils, diesel, kerosene, jet fuel, food and fuel additives, solvents, surfactants, lubricants, acids, synthetic reagents, boiler chemicals, and acetylene gas. Contamination investigations began in 1979 and remedial actions continue today on the upland portions of the site.

Permits and Field Coordination The Consultant shall be responsible for obtaining all necessary permits for the field work. Consultant shall be responsible for all coordination with the Owner, its subcontractors, and all entities as needed to accomplish the work. Consultant shall coordinate work with all other work, if any, being performed onsite or in water during the field investigation.

Survey of Exploration Locations Consultant shall be responsible for providing an accurate survey of the horizontal location of each exploration as well as the elevation of the ground surface (or mudline). The horizontal accuracy shall be plus or minus 1 foot and the vertical accuracy plus or minus 0.1 foot. Consultant shall provide proposed methods used and its accuracy for approval prior to mobilizing to the field.

Waterside Borings A total of nineteen (19) waterside borings are currently proposed. The idealized locations of these borings are provided in Attachment A to this scope of work; Consultant shall determine actual location in the field based on access restrictions. Table 1 provides a summary of the borings, the purpose of the boring and the minimum bottom elevation.

Final dredge elevation is intended to provide from -40 to -45 feet of berth depth. Generally, minimum boring bottom elevations for the waterside structures assume a drill depth of 80 feet below the dredge or mudline elevation. This depth should be reevaluated during the exploration, and if soft or loose soil conditions are encountered or there are changes in the axial loads for the piles the drilling depth may be increased. Consultant shall make its own evaluation of required access and drilling methods to perform the work. Consultant shall review the proposed borings of Table 1 and Figure 1 during the explorations and adjust the number, location, and depth of the borings as needed based on the result of the completed borings. Consultant shall receive approval from the Owner and CH2M HILL for any alteration in the exploration plan prior to implementation.

Landside Borings A total of four (4) landside borings are currently proposed. The idealized locations of these borings are provided in Attachment A to this scope of work; Consultant shall determine actual location in the field based on access restrictions. Table 2 provides a summary of the borings, the purpose of the boring and the minimum bottom elevation.

Consultant shall make its own evaluation of required access and drilling methods to perform the work. Consultant shall review the proposed borings of Table 2 and Attachment A during the explorations and adjust the number, location, and depth of the borings as needed based on the result of the completed borings. Consultant shall receive approval from the Owner and CH2M HILL for any alteration in the exploration plan prior to implementation. Drilling and Sampling Procedures Requirements of the drilling include, but are not limited to, the following: • The exploratory borings shall be observed and samples logged by staff trained in geotechnical

engineering or geology.

• The exploratory borings shall be advanced using hollow-stem auger, mud-rotary, or other acceptable systems. Casing or drilling mud is planned to be used as necessary to support the drilling operations. Hollow-stem auger shall not be used below the water table.

• Standard Penetration Testing (SPT) shall be planned at a minimum of 2.5 foot interval for the upper 10 feet and then approximately at 5 foot intervals thereafter for both landside and waterside borings. Where penetration exceeds 100 feet below the mudline, increase of the sampling spacing can be considered provided adequate sampling is performed to delineate subsurface stratigraphy. However, sampling spacing shall not exceed 10 feet. The SPT testing is to conform to ASTM D1586 requirements. More frequent testing may be performed if complex subsurface geology is encountered. The staff geotechnical engineer or geologist will record the method of SPT testing (e.g., automatic hammer, cathead with the number of wraps, etc.). Wireline or down-the-hole SPT systems shall not be used.

• Consultant shall provide calibration measurements taken within the past year for SPT energy transfer measurements for the individuals operating the SPT hammer during sampling. The measurements shall have measured the energy transferred from the hammer to the drill rod using strain gauges and accelerometers connected to Pile Driving Analyzer (PDA). Results of the measurements shall provide average computed transfer efficiency.

6

• Soil samples recovered during the SPT shall be logged according to ASTM D2488 and classified according to ASTM D2487. Representative samples recovered from all SPT sampling will be stored in appropriately labeled watertight polyurethane bags or glass jars.

• Relatively undisturbed samples (Shelby Tubes) shall be collected when soft to stiff clay or silt layers are encountered. Shelby Tube sampling shall conform to ASTM D1587. Pitcher or Osterberg sampling methods shall be employed, as needed, to obtain adequate samples in softer fine-grained soils. A minimum of one Shelby Tube sample shall be obtained in all distinct, fine-grained (silt and clay) soil strata greater then 5 feet thick. For thicker fine-grained strata, Shelby Tube sampling shall be obtained at intervals of no greater than 10 feet. Shelby Tube sampling shall be performed between SPT samples, as is reasonably feasible. Immediately after recovery the Shelby Tubes shall be sealed watertight using a combination of mechanical packers, plastic caps, and a sealing wax. All reasonable methods shall be used to minimize disturbance of the Shelby Tube samples during sampling, transportation, and storage. Shelby Tube samples shall be stored indoors.

Backfilling of borings shall be performed as required by Federal, State, and Local regulations. Laboratory Testing Laboratory testing on select samples shall be performed to aid in classification of subsurface materials, define pertinent engineering properties needed for foundation design, and assess corrosion potential to buried concrete and steel. All tests shall follow the appropriate ASTM standard. Tests shall include, but are not limited to, the following:

• Index Testing. Atterberg Limits (ASTM D4318), particle-size analysis with and without hydrometer (ASTM D422), natural water content (ASTM D2216), and organic content (ASTM D2974) on selected samples to aide in classification of the encountered soil layers.

• Torvane and/or pocket penetrometer testing of selected undisturbed samples (Shelby Tube) samples.

• Laboratory vane-shear strength testing per ASTM D4648 of selected undisturbed samples (Shelby Tube).

• Corrosion testing of selected samples to determine the corrosion potential of the soils against steel and concrete, and will include soil pH testing according to ASTM G51 and soil resistivity testing according to ASTM G57. Chloride, sulfate, redox and sulfide testing will also be considered.

• California Bearing Ratio (CBR) for pavement design following ASTM D1883 shall be performed. These shall be conducted on select subgrade materials.

• Consolidation tests following ASTM D2435 of selected samples collected in Shelby Tubes in clayey layers underlying areas of land reclamation. Samples for consolidation testing shall be trimmed into the consolidation ring after extruding the soil from the Shelby tube.

7

• Unconsolidated undrained (UU) and triaxial consolidated-undrained (CU) with pore pressure measurements strength tests conforming to ASTM D2850 and ASTM D4767, respectively, may be conducted on select Shelby Tube samples of cohesive soils to determine the strength properties of the soil. Samples for triaxial shear testing shall be trimmed after extruding the soil from the Shelby tube. Sample selection may require x-ray diffraction of Shelby Tubes prior to extrusion.

• Direct shear (ASTM D3080) may be conducted on recompacted cohesionless soil samples to estimate strength properties.

An estimated testing schedule is provided in Table 3.
