Spiniello Successfully Installs Emergency 120" CIPP Liner - City of Baltimore, MD

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.

Spiniello Responds To Large Diameter Sewer Collapse - Baltimore, MD

Spiniello Responds To Large Diameter Sewer Collapse - Baltimore, MD

Spiniello responds to a large diameter sewer collapse causing major sink holes and road closures in downtown Baltimore City.  Spiniello was called to the scene in April 2016 and quickly mobilized a temporary bypass system to bypass the collapsed area of the old 72" concrete and brick sewer main. Once the main was bypassed, the 30 foot deep sewer main was excavated and shored at the collapse to allow for cleaning of the sewer and rehabilitation by Cured-In-Place Pipelining.

Spiniello Receives Honorable Mention for Trenchless Technology Rehabilitation Project of the Year

Spiniello Receives Honorable Mention for Trenchless Technology Rehabilitation Project of the Year

Spiniello’s successful completion of the S.W. Diversion Pressure/Gravity Sewer, Phase III for the City of Baltimore receives “Honorable Mention” for Trenchless Technology Rehabilitation Project of the Year.

Also as part of the project, seven manholes and one bar screen structure that was the convergence of the upstream 54-in. and 66-in. sanitary sewers to the 78-in. In order to complete the rehabilitation of the sewers and the structures, a bypass pumping system had to be set up and operated throughout the course of the rehabilitation. This included eight 24-in. diameter HDPE bypass pipes that were routed a total of 5,600 lf around the repair area. Also sixteen 18-in. pumps were set up to bypass the flow (three being stand-by pumps) from the SWDS, and four 8-in. pumps to bypass the flow (one being a stand by-pump) from the Maidens Choice Pressure Sewer that connects into the SWDS. Spiniello was the prime contractor for the project. Sunbelt was the contractor that completed the bypass pumping and Structural Technologies performed the CFRP lining.

Spiniello Successfully Completes One of the Largest Sewer Bypass Performed in the Mid-Atlantic Region to Date - Baltimore City, MD

Spiniello Successfully Completes One of the Largest Sewer Bypass Performed in the Mid-Atlantic Region to Date - Baltimore City, MD

Working in conjunction with Spiniello, Sunbelt Rentals Pump & Power Services division executed one of the largest sewer bypasses performed in the Mid-Atlantic to date.
The City of Baltimore released the Sanitary Contract 875 — Rehabilitation of Southwest Diversion Pressure Gravity Sewer — Phase III in early June 2013 with a bid date of Aug. 28, 2013. Designed by engineering firm RK&K, the scope of the project included the trenchless rehab of a 78-in. pre-stressed concrete cylinder pipe (PCCP) utilizing two types of rehab technologies. The first method involved the use of approximately 2,550 lf of CIPP, and the second included 2,140 lf of carbon fiber reinforced polymer (CFRP). This project also required the rehabilitation of a bar screen structure at the upstream section of the 78-in. pipe in which two interceptors converge (one 54-in. and one 60-in.) to form the 78-in. pipe. Lastly, and perhaps most critically, was the provision and maintenance of a dry work environment while the rehab work was performed.
