The Harris Creek Storm Drain starts at Eager and Wolfe Streets and traverses roughly 8,000 ft in a southerly route through East Baltimore. The drain was constructed between 1882 and 1888 using brick and mortar and installed using traditional cut-and-cover, tunnel or cradle construction methods. The entire Harris Creek watershed services roughly 1,300 acres, with the large portion of that being dense urban portions of the city.

Following the collapse of a section of the drain located in Monument Street in 2012, Baltimore City DPW Storm Drain Engineering Section engaged in a contract to inspect, assess and develop a maintenance and rehabilitation plan for the 8,000-ft long drain. The DPW conducted video and laser profiling inspections, which indicated severe deterioration. The approximately 400-ft long segment of drain along Eager Street from Wolfe Street to Washington Street is a 10-ft diameter round section constructed of brick and mortar with a stone invert. The brick walls and crown are approximately 1.5-ft thick and the invert is constructed of granite cobble stones.

Plans, special provisions and construction cost estimates were prepared by RK&K for the emergency repair of the severely deformed 100-ft long segment of the storm drain using one of three structural repair options. These included: 1) cured-in-place pipe (CIPP) lining; 2) carbon fiber reinforced polymer composite (CFRP) lining; and 3) conventional open-cut repairs using cast-in-place concrete. Plans and repair options were presented to contractors in a pre-bid meeting held in February. The lowest responsive bid, submitted by Spiniello Companies, entailed the use of CIPP to structurally repair the drain.

A pre-construction meeting was conducted in March and Storm Drain Contract (SDC) No. 7790 was awarded to Spiniello, with a completion schedule of 60 calendar days. Working closely with DPW, RK&K assisted with the emergency repair by providing construction phase services, including construction oversight and inspection.
