Solicitation Number: 130140
Solicitation Title: Spring Valley Water Main Rehabilitation and Replacement

Solicitation Information

Commodity Code(s): 237990 - Other Heavy and Civil Engineering Construction
237110 - Water and Sewer Line and Related Structures Construction
Solicitation Description:

The District of Columbia Water and Sewer Authority (DC Water) is soliciting bids for Invitation for Bid No. 130140 for Spring Valley Water Main Rehabilitation and Replacement. The Work includes structural (Class IV) lining of approximately 3,400 linear feet of 8-inch through 12-inch water main; installation of approximately 205 linear feet of new 12-inch water main interconnection between a 12-inch and a 16-inch water main, replacement in the same trench approximately 1,300 linear feet of existing 8-inch water main with 12-inch water main; providing temporary water system of approximately 10,700 linear feet of 4-inch pipe and appurtenances in Spring Valley, including 49th Street NW, Woodway Lane NW, Hillbrook Lane NW, Glenbrook Road NW, Rockwood Parkway NW, and Nebraska Avenue NW, Washington DC; and associated paving, sidewalk, curb and gutter, undercut trench excavations and borrow trench fill.

Prospective Bidders should note that Spring Valley is located within a formerly used defense site, consisting of 661 acres in the northwest section of Washington, DC. During World War I, the defense site was known as the American University Experiment Station. Over the past 20 years, the US Army Corps of Engineers in partnership with the U.S. Environmental Protection Agency and the Washington, DC District Department of the Environment has conducted extensive investigations and cleanup actions within the area. The bulk of the finds have been discarded military munitions and munitions debris that were mostly unfuzed and unfired. Confirmed unexploded ordnances (fuzed and fired) have not been found to date. The Army recently completed a multi-year effort to remove arsenic contaminated soil from several locations within the defense site. The defense site is not designated as a Superfund site.

Since the existing water mains were constructed after American University Experiment Station was closed, it is unlikely that any chemical warfare or explosive materials will be encountered during construction of the water main upgrades. However, because it is possible that such materials could be encountered, DC Water has adopted a conservative approach to reduce risk, including performing soil testing during design by coring through the pavement and collecting samples for laboratory analysis to test for arsenic; minimizing excavation by lining water mains where existing pipe size is adequate and replacing water mains in the same trench where pipe upsizing is needed; and requiring the Construction Contractor to have an unexploded ordnance specialist be present to observe excavation work during construction.

A Mandatory Pre-Bid Meeting will be conducted on June 7, 2016 at 9:00 am in the Visitor Center classroom at DC Water Blue Plains Advanced Waste Water Treatment Plant, 5000 Overlook Avenue, SW, Washington, D.C. 20032. Potential Bidders who plan to attend the Mandatory Pre-Bid Meeting are requested to make a reservation by June 6, 2016, noon by sending an email to susan.macneil@dcwater.com.
