Duffield provided engineering services for the design, bidding, administration, and inspection of an approximate 1,250 linear feet extension of an existing 8” gravity sewer along River Road. An archeological survey was performed preceding the sewer installation and consisted of mechanical stripping operations, shovel test units, and delineation of soil anomalies. During the archeological survey, 27 unmarked human burials were found within the proposed limit of construction of the new gravity sewer extension. As a result, Duffield revised the sewer design during construction so that the new 8” sewer would be installed by jack and bore beneath the human burials. Thus, the burials remained undisturbed, in situ and the project continued on schedule to completion.
