Amott Drainage Culvert Inspection and Rehabilitation

LIRR's Amott Drainage Culvert
Project Overview: 
For the Port Jefferson Branch of the LIRR, McLaren is providied site/civil engineering services for the rehabilitation of the Amott Drainage Culvert between mileposts 30.3 and 30.6. The culvert's drainage deficiencies resulted in a washout that undermined the supporting structure of the north track and caused a train derailment. The culvert system consists of a street level drainage easement and overflow catch basins, a concrete spillway, collection box, two 36-inch diameter pipes approximately 36-feet long parallel to each other and perpendicular to the railroad tracks, a discharge headwall and spillway outflow area.
McLaren's Role: 
Because the project required the construction of approximately 1,900 feet of trackside drainage adjacent to the railroad tracks, as well as a new or additional culvert at the existing Amott Culvert; McLaren conducted a geotechnical investigation to determine the bearing capacity and presence of weak soil strata. To minimize the occurrence of track outages, McLaren designed the construction to be completed in phases. The final drainage design required a minimum of maintenance, and extended the drainage system service life for at least 30 years.
