The United States Section of the International Boundary and Water Commission (USIBWC) is issuing a Solicitation for the replacement of the hydraulic system for Penstock #5 in Amistad Dam.  This penstock has not been functional in several years.  The successful Offeror will fully inspect system and structures and replace hydraulic system to fully restore Penstock #5 to full functionality.

The Construction includes, but is not limited to, site preparation, inspection of all systems and structures, replacement of Penstock #5 hydraulic system, disposal of debris and construction waste, quality control testing, and if awarded, the manufacturer of a new penstock bulkhead.

The following site constraints apply:

• The working hours of the adjacent USIBWC facility are 7:00 am to 3:30 pm, Monday through Friday. The Contractor and any subcontractors shall only work onsite during these proposed hours.  USIBWC facilities, including the dam, are closed during all Federal Holidays.
• There is currently only 1 penstock bulkhead, located at Amistad Dam and it is moved via mobile crane. Only 1 penstock can be bulk headed at a time for servicing so design inspections must be coordinated with Amistad Field Office AOM through the COR.  Amistad Field Office does not have a certified crane operator at this time so the Contractor must provide a crane an certified operator to perform the relocation of the bulkhead. Several relocations may be required.  The bulkhead is approximately 14.3 feet wide by 24.6 feet tall.  The weight of the bulkhead gate with lifting beam is approximately 33,000 pounds (16.5 Tons).
• Access to the site is made via Texas Spur 349. Texas Spur 349 bridge inventory rating is limited to HS-20. The load capacity of the embankment crest road is 70,000 pounds.
• Workers must pass through the port of entry to access the worksite.  The port of entry is open from 10:00 a.m. to 6:00 p.m.  DHS may change these hours without notice.  If the Contractor requires to begin work prior to the port of entry opening or after closing, this must be coordinated with the Amistad Dam Area Operations Manager.  Workers crossing through the port of entry need to have proper documentation for reentry to the United States.

Per FAR 36.204, the magnitude of the project is estimated between $1,000,000 and $5,000,000.
