CELRB-TD-DC 19 August 2019

MEMORANDUM FOR FILE

PREPARED BY: David Mitchell, P.G., P.E.

SUBJECT: Geotechnical Logs of Supplemental Borings – Rochester East Pier Repair 2019.

PURPOSE: Supplemental Bidding Information to provide to prospective bidders.

Geotechnical Investigation

From July 30th through 31th, 2019, SJB Services, Inc. (SJB) on behalf of USACE, conducted a subsurface exploration program within the project area with the purpose of supplementing the existing subsurface data and understanding of the geologic and geotechnical conditions along the Rochester East Pier. The field program included the installation of three exploratory borings along the pier with one boring located on the west side of the pier and two borings along the eastern side of the pier. Figure 1 presents the location of the borings. Standard penetration testing along with the collection of split-spoon samples for field and laboratory testing was conducted within each borehole along with field classification of the soil strata encountered.

Attached are the logs for each of the borings along with standard penetration test data. These logs are in pre-final status and will be subsequently finalized to include testing results of selected samples upon completion of laboratory analyses.

Note: The information provided is for exploratory locations offset from the pier and planned sheetpile driveline.

Existing subsurface conditions along the sheetpile driveline have not been specifically investigated.

Exploration logs reflect conditions at the exploration location at the time of exploration. Actual subsurface conditions may vary from those indicated on the exploration logs. Prior to bid submission, USACE recommends that the Contractor examine the project site as needed to establish their own conclusions regarding subsurface conditions.
