RFQ D/B - Line 54-Inch Outfall Research to I-95

Drilling for the authorized subsurface exploration was performed during the period February 25 through March 5, 2021 in conformance with our proposal RD22783R1, dated November 23, 2020. Occasionally some modification to work scopes appearing in our proposals is required to provide for proper evaluation of encountered subsurface conditions. Modification to the scope for this project has included performance of 10 additional moisture content tests for evaluation of subsurface moisture conditions. No other modifications to the work scope were required to complete this work. The purpose of the geotechnical exploration has been to assess general subsurface conditions at specific boring locations and to gather data on which to base a preliminary geotechnical evaluation with respect to the project. Subsurface exploration for this project consisted of thirteen (13) soil SPT borings and three (3) Kessler DCP borings; soil classification has only been performed in the SPT borings. The site was drilled using a CME 550X ATV drill rig equipped with a manual hammer; DCP borings were performed with a hand auger and ASTM compliant dynamic cone penetrometer. Soil boring sites were field located by a representative of our staff using a Garmin GPSmap 64. As such, boring positions appearing on the Boring Location Plan, attached to this report, should be considered approximate. A boring plan was provided to the client prior to commencement of field work. Questions regarding this Request for Qualifications shall be submitted in writing to the attention of Tanya Hazlett via e-mail to tanya.hazlett@faypwc.com, no later than 5:00 p.m., February 28, 2023 Interested firms must email Tanya Hazlett, PWC Procurement Advisor at tanya.hazlett@faypwc.com of their intent to attend. It is the intent of PWC to have the Project substantially complete by April 2027. The milestone completion dates are as follows: o February 2026-Stabilize embankment and maintenance road improvements. o February 2027-Lining the outfall. The estimated budget for this work is $8,600,000
