Colorado Springs Utilities awarded Garney this $25.9 million contract to install 33,865 linear feet (LF) of 66″ cement mortar-lined and polyurethane-coated welded steel pipe through Pueblo West. Construction involved 355 LF of 78″ cased crossing by tunneling, five combination air and vacuum valve assembly vaults, six blow-off assemblies, and 70 LF of open cut casing. This project included deep excavations, some of which were greater than 30 feet deep, and crossed through 133 residential properties.
Work for this $26 million construction contract is broken up into East and West portions, separated by Interstate 25, and begins at the Pueblo/El Paso County line. The West portion consists of 26,980 LF while the East side includes 12,669 LF of 66″ cement mortar-lined and polyurethane-coated spiral weld steel pipe. Other project components include asphalt pavement replacement, fiber optic conduit installation, traffic control, erosion and sediment control, and re-vegetation.
Work for this $19.7 million design-build contract consists of 5,207 LF of tunnel for a 66″ raw water carrier pipe through a 105” diameter tunnel under Interstate 25, two railroads, Fountain Creek, and nearby frontage roads north of the Pueblo/El Paso County line. This project helps preserve environmentally-sensitive areas through tunneling under nearby wetlands. The project also includes 2,106 LF of open cut 66″ cement mortar-lined and polyurethane-coated spiral weld steel pipe to connect the tunneled pipe to the nearby South 4A West pipeline segment.
This $11.5 million contract involves the construction of 16,900 LF of 66” cement mortar-lined and polyurethane-coated spiral weld steel raw water pipeline in El Paso County along Highway 94. The project consists of 150 LF of trenchless method pipeline crossing of Highway 94, 170 LF of open trenched cased installation, combination air release and vacuum valve assemblies and vaults, surge CARV, blowoff assemblies, buried access manways, 16,845 LF of fiber optic conduit and fiber optic handholes, surface grading and restoration, maintenance of re-vegetation, and connections to existing lines. This project also includes a pipeline cathodic protection system consisting of anodes, test stations, and appurtenance grounding mats.
These projects include contracts for three work packages near Pueblo Dam totaling $10 million for construction. (1) The Pueblo Dam Connection 1B extends a 90″ polyurethane-coated spiral weld steel pipeline with a specialized lining approximately 1,511 LF to the Bureau of Reclamation future interconnection point and the beginning of the SDS pipeline. (2) The Pueblo West Connection (PWC) includes 58 LF of 36″ welded steel pipeline that wyes off the PDC1B pipeline, two 24″ reducers, 30 LF of 24″ pipeline, a meter vault, and 24″ meter. Completion of this work package will allow water service to Pueblo West Metropolitan District (PWMD). (3) The PWMD River Pump Station Suction Side Improvements (RPSSI) includes 290 LF of 36″ pipeline that links the PWC to the PWMD pump station. This work package includes the construction of two flow balancing vaults and valves, connection to the existing 24″ transmission line currently serving the pump station, a new manifold for the pump station, and power, instrumentation and controls for the meter vault installed as part of the PWC work package.
Work on this $7.3 million contract along Constitution Avenue in Colorado Springs includes the installation of 11,500 LF of 36″ cement-mortar lined and polyurethane-coated welded steel pipe, three trenchless crossings with 48″ steel casing and one liner plate hand tunnel, the relocation of three existing waterlines, and extensive asphalt pavement restorations.
This $3.6 million contract included the installation of 3,700 LF of parallel 42” and 54” cement mortar-lined and polyurethane-coated spiral weld steel water pipelines prior to a road widening project. The schedule was short and the project consisted of many challenges, including extensive traffic control and excavating and exposing the ends of an existing bore that were threaded with the 42” pipeline. Both pipelines were installed in a common trench for 2,800 LF. The pipelines crossed Sand Creek where a dewatering system was installed.
This $3.1 million contract includes the installation of 2,043 LF of 54” and 2,055 LF of 42” cement mortar-lined and polyurethane-coated welded steel dual pipelines, two 425 LF cased tunnel crossings, combination air and vacuum valve assembly vaults, construction of a temporary sediment basin, asphalt pavement replacement, traffic control, and erosion and sediment control.“Garney has performed a significant amount of work on SDS for Colorado Springs Utilities. Their team has continuously delivered quality construction and serves as good partners on this historic regional water project.”
