Gregory Avenue and Lowell Avenue Safe Routes to School Preliminary Engineering, Final Design, and Construction Engineering Services Page 14 Preliminary Engineering – Scope of Work STV will solicit bids for the geotechnical subsurface investigation and will advance the investigation. While the final geotechnical investigation program will be dependent on the final limits and heights of the retaining walls and BMPs, for pricing purposes, STV assumes that a total of 4 borings will be performed along the two Lowell Avenue retaining walls. Despite its conceptual length, we assume that only 2 borings will be performed for the Gregory Avenue retaining wall due to the cut section and expected height of less than 3 feet. All borings will be performed to a depth of 15 feet below ground surface with continuous SPT sampling. If predominantly fine-grained cohesive soils are encountered, relatively undisturbed Shelby tube samples will be attempted. We assume that rock will not be encountered within 15 feet below ground surface. Based on the anticipated size of the stormwater BMP, we anticipate that two test pits to a depth of 10 feet will be required with infiltration testing consisting of single-ring infiltration testing performed in accordance with the NJDEP’s Stormwater Management BMP Manual. STV assumes that maintenance and protection of traffic (MPT) will be required for the borings but that no MPT will be required for the test pits or infiltration testing. STV will provide a geotechnical engineer or geologist on-site full-time to monitor the investigation, to visually classify encountered soil using the Burmister Soil Identification Method, and to collect representative samples for possible laboratory testing. For the test pits, STV will identify indications of the seasonal high groundwater table, e.g. mottling. STV will select samples for laboratory testing, expected to consist of soil index testing, consolidation testing, and soil shear strength testing. The results of the stormwater investigation will be presented as part of a Stormwater Investigation Memorandum, including seasonal high water table elevation and infiltration testing results. Based on the results of the investigation program, STV will determine soil design parameters. Based on

Memorandum, including seasonal high water table elevation and infiltration testing results. Based on the results of the investigation program, STV will determine soil design parameters. Based on the conceptual height of the walls, we will consider segmental block walls, modular block walls, and concrete cinder block walls, similar to those installed by NJDOT at Tichenor Park in Newark for both cut and fill sections. STV will perform wall stability (bearing, sliding, & eccentricity), global slope stability, and settlement analyses and develop geotechnical recommendations for the retaining walls. We will also assess the use of lightweight fill to mitigate potential settlement or imposed lateral loading impacts. STV will summarize the results of the geotechnical investigation, analyses, and recommendations as well as construction considerations as part of the Geotechnical Engineering Report.
