REMPREX provided the full scope of site and technology design, as well as subsequent construction management, for the largest AGS system in a domestic intermodal terminal to date. The project encompassed 34 AGS lanes and four Optical Character Recognition (OCR) portals in seven gate areas across the 300-acre site. The massive site posed several design and construction challenges above and beyond those typically associated with an AGS installation in an operating yard. The most significant of these was the in-fill of nearly 3,000 lineal feet of former public street right of way (ROW) required for the relocation of 78 chassis racks (2,500 racked chassis) to make room for the new inbound gate. The work in the former ROW required the relocation of manual gate operations prior to the start of demolition work in the existing gate facilities.

Working closely with local site operations, REMPREX developed a construction and phasing plan that maintained gate capacity in a temporary location. REMPREX also worked with the contractors to develop and implement an in-place recycling method in the chassis storage area to cement-treat the existing pavement materials that were pulverized in place. This method dramatically reduced the amount of materials that needed to be removed from the site for disposal and the cost savings of doing so allowed for the full reconstruction of the deteriorated pavement in the chassis storage area and inbound gate-queuing lanes. The inclusion of remote parking lots in the Hobart complex required REMPREX engineers to work closely with REMPREX technical staff and the BNSF intermodal IT and process team to accommodate the remote facilities that were limited in physical footprint and AGS scope. REMPREX also coordinated with designers and contractors who were constructing a new overpass that linked the largest of the remote lots with the main yard. The overpass spanned an AGS gate and required coordination of design planning and construction activities between both projects.
