Update of Electric Structures along Metro-North Rail Line

United Illuminating is updating their electric structures along the Metro-North MN) rail line in Milford and Bridgeport. BL Companies has been retained by Black and Veatch, Program Manager, to perform investigation (Task 210) and remediation design services (Task 310), construction/remediation oversight (Tasks 610, 611, and 620), as well as wetland delineation, geotechnical engineering, subsurface utility engineering and land surveying services. Prior to conducting the subsurface investigation, BL Companies field marked the proposed boring locations for utility clearances and obtained ROW permits from the State of Connecticut for work within the MN ROW. The subsurface investigation consists of the advancement of more than 50 soil borings and 75 geoprobe borings, and the collection of soil and ground water samples for analysis for the presence of regulated compounds. The analytical parameters were chosen based on field screening information, current and/or historic site usage in the vicinity of the soil borings and an evaluation of contaminants that could change the classification of soil from a Connecticut “regulated” waste to hazardous waste. The intent of the subsurface investigation is to obtain pre-authorization from selected disposal/recycling facilities to enable the contractor to direct load and transport excess material excavated during the proposed infrastructure improvements from the site (if desired) to an owner-approved disposal facility without using a temporary stockpile area. The intent of the groundwater classification was to prepare and secure all local and state regulatory permits required to treat and discharge groundwater during construction dewatering activities. BL Companies also provided land surveying support services for the environmental work. Specific survey tasks included the reestablishment of local control and the location of geoprobes and other sampling locations.
