The sinkhole was due to the collapse of a timber box culvert that carries a portion of the Davis Brook overflow. The proposed repair plan includes removing the remaining 50 feet of timber box culvert and replacing it with 6'x 7' concrete box sections. In addition, it will include removing and replacing 3 sections of existing concrete box culvert (181 nearest to the river. The total length of new box will be about 74'. This repair is very difficult due to several factors that include limited work window due to the work being in the tidal zone, the winter weather conditions, depth of the existing culvert (about 22� and the close proximity of the existing Davis Brook storage facility and the 42" Penobscot sewer interceptor pipe. Staff reviewed the ability and availability of a number of local contractors. Staff recommendation is to execute a change order to an existing contract with Lou Silver. Lou Silver currently has the equipment and materials available to complete the repair. Due to the emergency nature of this project, DEP has agreed to allow this project to become a change order to an existing SRF loan funded project, ensuring compliance with all required federal regulations. Due to the importance of this project, staff has requested that Lou Silver begin this project as soon as possible and will likely be mobilizing equipment in the next couple of days. Funding for this project is available from savings in the recently completed Bio Media tower project.
