This project includes the replacement of the existing structurally deficient and red-listed bridge constructed in 1984. After completion of the design by another consultant, Hoyle Tanner provided construction observation and administration. Due to contractor’s means and methods, an amendment of the wetland permit was required, and Hoyle Tanner personnel assisted in getting the amendment approved by NHDES in a timely manner, avoiding any construction delays. The project also required extensive coordination with affected overhead utility owners and the engineer of record in order to keep the construction of the project on schedule and on budget. Prestressed plant inspections were also completed to perform quality assurance for the fabrication of the prestressed beam elements.
