SPANISH FORK CANYON REACH 2 PIPELINE
$27.5 Million- Completed 2010
The Spanish Fork Canyon Reach 2 Project involved the construction of a 96” diameter mortar lined and coated steel pipeline within the shoulder of the heavily traveled US Highway 6 for a distance of 2.75 miles. Each pipe were forty feet long, weigh 55,000 pounds and the joints were welded together both inside and out. The pipeline is installed at an average depth of sixteen feet in a work zone only 50 feet wide. Portions of the excavation had to be blasted from solid rock and other sections included extensive dewatering with protection of springs and a nearby river.
OGDEN CANYON PIPELINE REHABILITATION PROJECT
$10.6 Million- Completed in 2013
This CMGC pipeline rehabilitation project consisted of replacement of approximately 23,000-lf of existing steel with 24" PVC waterline in UDOT ROW (Hwy 38). This project was complicated by the extremely narrow work area of 12' to 15' widths, UDOT constraints, steep hillside construction and the need to complete much of the project during the winter months when the existing pipeline could be shutdown. Other challenges on the project include maintaining canyon traffic during construction, providing temporary water for over 100 homes for the duration of the project and rock excavation.
DEWITT PIPELINE REHABILITATION PROJECT
$8.3 Million- Completed in 2009
This project consisted of installation of 10,500 feet of thirty-six inch welded steel pipeline. There were several items which made this project interesting and difficult. First, we had to cross the Logan River at three different locations which needed extensive bypass pumping and stream alteration techniques. Second, we had a number of areas of solid rock which required blasting and rock removal in the narrow area at the edge of the highway and next to the existing waterline. Third we had an extremely narrow work area in the public right-of-way next to the highway, through a steep hillside adjacent to the river, and behind the existing power plant buildings. Finally, we had an extensive traffic control plan which required the busy highway to be reduced to one lane with pilot cars to direct traffic around our work area.
MANTUA EAST SPRINGS REPIPING PROJECT
$4.6 Million- Completed in 2019
This CMGC project includes construction of 14,400-ft of 24” to 30” PVC Pipe, 1,200-ft of directionally drilled 18" to 24” HDPE, valves and structures to connect to the City's main spring water supply. The work requires extensive dewatering, working in narrow easements and restoration.
CUWCD - VINEYARD WELLFIELD COLLECTOR PIPE
$16.5 Million- Completed in 2019
This CMGC project included construction of 14,500-ft of 24” thru 48” Welded Steel Pipe, 24” RCP well to waste pipe and electrical ductbank to connect 10 new culinary water wells. The work required working in very narrow easements, 5 tunneled crossings of the UPRR & UTA tracks, AV/BO vaults and turnout structures.
EAST LAYTON WATERLINE PROJECT
$5.1 Million- Completed in 2016
This CMGC project included installation of approximately 7,000 feet of new 36" welded steel waterline, 1,500 feet of 42" HDPE waterline and associated blow-offs, air-vacs and connections. The project also required multiple utility relocations and extensive restoration.
NORTH SHORE AQUEDUCT
- NORTH & WEST SEGMENTS
$18.9 Million- Completed in 2012
This project included the construction of 2.6 miles of 60" and 3 miles of 48" welded steel water transmission pipeline, (3) cast-in-place concrete turnout valve vaults and (2) bored casings under UDOT ROW (1-72" & 1-60"). Work also included air valve/manway vaults, traffic control, asphalt restoration and field restoration.
