The small diameter SBU-M is typically used with welded steel casing; however on longer projects, the casing can be bolted and pushed out with Reinforced Concrete Pipe (RCP). This paper discusses the development of the new machine design and application at its first project in Muscat, Oman. ...
Since the official introduction of the S4 test in several ISO and CEN standards, different test institutes have achieved experience in the RCP behaviour of polyethylene gas and water pipes. In most cases the S4 test is limited for smaller pipes up...
In the United States, many of these large diameter sewers are constructed of reinforced concrete pipe (RCP) and have been in service well past their design life. As a result, headlines of sinkholes, pipe collapses, and overflows when these sewers fail have become more frequent. Such failures...

This has allowed for the transfer of flow to the new pipeline and the evaluation of three parallel pipelines, two 72-inch and one 96-inch diameter reinforced concrete pipelines (RCP), the oldest of which was constructed in 1959. With the assistance of three engineering firms for these ...
of RCP and steel casing pipe has been installed with GBM and traditional pipe jacking methods in 63 drives, all with an average of six-foot depth of cover. This total linear footage of 18 to 72- inch ID storm water pipelines was installed equally between the two methods upon completion of...
The major challenge in this case was the presence of a poorly designed, gravity fed sewer line situated 2-ft about the proposed casing line. The second case study involves the installation of a 30" diameter RGRCP pipe which required a 502-ft BMTA to install a 60" O.D. steel casing. ...
The corroded section of 42-inch diameter reinforced concrete pipe (RCP) was located in an area that was difficult to access, making trenchless rehabilitation the best overall option. As was discovered in this project, alternative construction proposals can also throw a monkey wrench into the ...

The total length of the NPSSI is approximately 47,000 feet and it is constructed of unlined reinforced concrete pipe (RCP). Concerns over hydrogen sulfide (H_2S) corrosion prompted the City to undertake a condition assessment. The City wanted to establish a baseline assessment of the NPSSI ...
