The county commissioners on Wednesday awarded $4.2 million in contracts to county and regional contractors for the Marion Township sewer project that is aimed at providing sewer service for at least 111 homes in Boyers by the end of the year.

The commissioners awarded a $2.2 million sewer plant construction contract to Bison Construction of Fairmount City in Clarion County, a $1.2 million contract to install sewer collection lines to Mortimer’s Excavating of Pulaski in Lawrence County, a $475,196 contract to provide 87 grinder pumps, pump housings and lateral service lines that will be installed at some homes to Trombold Equipment Co. (Tepco) of Mars, and a $265,000 contract for electric service installation to Right Electric of Butler.

A contract for engineering and inspection services was awarded to EADS Group of Clarion, based on qualifications. A do-not-exceed cost of $341,695 was negotiated for two full-time inspectors and one engineer, but county officials do not expect the final cost to be considerably less. Five firms responded to the county’s request for qualifications for the project.
