Pipeline rehabilitation projects total $21.7 million
SAK Construction (SAK) started work on $21.7 million of contracts throughout the Baltimore, Md., and Washington, D.C., regions. SAK is repairing the sewer and pipeline infrastructure in these metropolitan areas without excavation or disruption by utilizing trenchless technologies, including cured-in-place pipe (CIPP) pipeline rehabilitation.
SAK was awarded the following projects as low bidder:
District of Columbia Water and Sewer Authority (DC Water), Washington, D.C.
- G100: Local Sewer Rehabilitation 1 is a $5.25 million contract for the rehabilitation of approximately 140 manholes and the replacement of existing sewer mains throughout D.C. Using CIPP, SAK will rehabilitate 15,000 linear ft of sanitary sewer pipeline, with diameters ranging from 12 to 24 in. The project is underway and will conclude in 2017.
- Rehabilitation of Sewers Under Buildings Phase 2 is a $3.6 million contract for the structural repair of sanitary sewer and combined sewer and storm water pipes under buildings at 19 sites throughout D.C. SAK will use CIPP, shotcrete and other methods to repair pipes ranging from a 10-in. diameter to a 108-in. height.
Baltimore County, Md.
- Herring Run Basin 31 is a $2.04 million contract for the rehabilitation of sewer lines in the Ridgeleigh Community, also known as “The Oaks,” situated near Loch Raven Boulevard and Joppa Road. The project includes 23,251 linear ft of CIPP pipe rehabilitation and 1,109 vertical ft of manhole rehabilitation. Completion is expected in December 2016.
- Stemmers Run Sewershed Rehabilitation is a $1.52 million contract for the rehabilitation of 23,665 linear ft of sewer pipeline and 882 vertical ft of manhole rehabilitation on the northeast side of the city of Baltimore. SAK will use CIPP as the solution with completion expected in September 2016.
- Jones Falls Basin BC09 Sewer Rehabilitation is a $2.74 million project located on the north side of the city of Baltimore for the rehabilitation of sewer lines between I-83 North, I-695, Timonium Road and York Road. A train system bisects the work area. SAK will use CIPP to line 34,868 linear ft of sewer lines and will rehab 1,588 vertical ft of manholes. The project is to be completed by February 2017.
City of Baltimore Bureau of Water and Wastewater, Baltimore, Md.
- SC 937 Chesterfield Ave, Herring Run Sewershed is a $6.59 million contract to rehabilitate a segment of the sewer system in the city of Baltimore. SAK will use CIPP to line 11,861 linear ft of sewer line. The company will also use CIPP to install 249 vertical ft of new manholes, 1,191 linear ft of new 8-in. PVC pipe, and 1,409 linear ft of new 16-in. ductile iron pipe. Work is to be completed by June 2018.
These projects reflect national demand for pipeline rehabilitation in response to America’s aging infrastructure. Collapsing, malfunctioning or inadequate water mains, sanitary sewers and storm sewers produce a variety of serious problems and threaten the water supply.
To address these needs while minimizing aboveground disruption, municipalities are seeking solutions to provide the newest underground trenchless technologies for pipeline rehabilitation. SAK also provides solutions for repairing drinking water mains from 6 to 16 in. in diameter. When expansion of existing water, sewer and storm water systems is required, SAK provides large diameter tunneling services for 48-in. diameter up to 32-ft arch-shaped.
