HILCON designed a replacement structure for the old Kedgwick River Bridge, which was destroyed by ice in 2012. HILCON’s team performed a full site survey, including river bottom and approaches, calculated peak flow estimates, built a hydraulic model, did an ice study of the site prior to structural design. Due to a compressed construction schedule and in stream work restrictions, an innovative 80m long pre-fabricated structure was launched across the Kedgwick River on HILCON designed abutments. This bridge was the largest single span structure of its kind in Canada at the time.

City of Fredericton
Marysville, New Brunswick

The City of Fredericton required a replacement structure for a failing steel culvert under the Nashwaak Trail. The high embankment also contained a water line and sanitary forcemain that had to remain in service during construction. HILCON completed the engineering survey, hydraulic design, including energy dissipators and full tender package for the City and provided full time inspection during construction.

HILCON Limited assisted the Department of Transportation and Infrastructure with the Full Mill Brook culvert replacement. This project involved replacing two failing culverts under Route 102 and an adjacent abandoned rail line, with a single concrete pipe. The project included engineering survey, hydraulic design, fish passage design, realignment of the abandoned rail line (and conversion to a pedestrian trail) as well as construction detour design to keep the site open during construction.

HILCON’s team performed a field survey and investigation and developed a storm water management model of the Back Drain in Fredericton, New Brunswick. The back drain has a length of approximately 2.3km and increases in pipe diameter from 750mm to 1500mm along its length as it intercepts several secondary storm water lines. The model identified several hydraulic deficiencies and is an important tool for analyzing the impact of land use on storm water run off.
