Repair Tainter Gates 1&2 at Amistad Dam, Texas

Purpose of the Project The United States Section of the International Boundary and Water Commission (USIBWC) requires inspection, maintenance, repairs and testing of civil, mechanical & electrical facilities and the hoist system/ platform for Tainter Gates number 1 and 2 at Amistad Dam is located about 15 miles from downtown Del Rio, TX. Background Gate No. 2 is one of sixteen 50 feet by 50 feet Tainter Gates designed for spillway releases. The background to the required inspection, maintenance and repair of Tainter Gates number 1 and 2 under this contract is as follows: - In April 2015, a Grove TM 9120 Crane tipped onto its side and damaged the gate hoist assembly for Tainter Gate #2. - A visual inspection indicates that an oil feed line is bent and may have to be replaced. Also, the drive shaft from Gate #2 Gate Hoist to the Gate #2 Bull Gear (located on the Gate #3 Gate Hoist Platform, 50 feet away) is bent and must be repaired or replaced. - The hand rail and catwalk around Gate #2 hoist platform are missing; apparently, they were sheared off by the tipping crane and fell in the river. Currently there is no fall protection on Gate# 2 hoist platform. - The Limit Switch housing was broken during the crane incident and the Limit Switch and screw drive appear to have been damaged. - A spare Limit Switch housing, switches, and screw drive are available on site from decommissioned penstock gates hoists (penstock #4); and may be suitable to use for Tainter Gate No. 2. - Gate number 1 drive shaft support frame and support bearing have been impacted by the incident. They are to be inspected and repaired. - During subsequent attempts to remove the crane, a fire broke out damaging wiring in an electrical pull box, located in front of the Tainter Gate #2 platform. Replacement of wiring and cables damaged by the fire IS NOT part of this project. - The USACE conducted an inspection during September 2015 and provided recommendations for the electrical repairs. The report is summarized as "Amistad Electrical Evaluation Report." General Description of the Work 1.
