SPECIFIC REQUIREMENTS

USIBWC requires construction services to permanently plug Penstock No. 4 at Amistad Reservoir and Dam. Penstock No. 4 was designed for irrigation use and has not been operated for irrigation purposes for several decades. The work is intended to eliminate the need for continued maintenance of the Penstock and Irrigation Gates by permanently plugging the penstock and removing related gate components.

The work is specialized and involves dam infrastructure, confined access areas, water control features, heavy lifting, unwatering, concrete placement, structural concrete repair, grouting, gate removal, and safety controls. The Government is seeking firms with demonstrated experience performing comparable work in similar high risk construction environments.

The anticipated work includes, but is not limited to, the following:

Permanent plugging of Penstock No. 4. Unwatering of Penstock No. 4. Construction of concrete plug features within dam infrastructure. Structural concrete repair associated with the penstock and dam features. Removal of penstock and irrigation gate components. Grouting and related concrete repair work. Hoisting, lifting, rigging, crane support, and use of manlift equipment. Work in confined or restricted access areas. Compliance with dam safety, construction safety, and site access requirements. Coordination with USIBWC personnel for access, work hours, security, and site controls.

The worksite includes access limitations. The adjacent USIBWC facility generally operates from 7:00 a.m. to 3:30 p.m., Monday through Friday, excluding Federal holidays. Access to the site is made through Texas Spur 349. Workers must pass through the port of entry to access the worksite. The port of entry is generally open from 10:00 a.m. to 6:00 p.m. Department of Homeland Security hours may change without notice. Workers crossing through the port of entry must have proper documentation for reentry to the United States.

The work also includes physical site limitations, including load restrictions on Texas Spur 349 and embankment crest road limitations. Interested firms must be capable of planning and performing work under these access and site constraints.
