SCOPE OF SUPPLY

AMISTAD DAM FIELD OFFICE

SUPPLY OF A MOBILE CRANE

I. GENERAL REQUIREMENTS

The vendor is required to supply one mobile crane complete with all the accessories including counter weights, rigging equipment, hook blocks, an additional single sheave snatch block and operations and maintenance manuals; all in accordance with Article III “Scope of Supply” and Article VI “Deliverables”.

II. BACKGROUND

A. Amistad Dam, constructed and completed in 1969 by the United States (U.S.) and Mexico pursuant to the Water Treaty of 1944, is located on the Rio Grande 12 miles northwest of Del Rio, Texas, 574 river miles above the mouth of the Rio Grande, and 1 river mile below confluence of the Devils River.

B. The dam is used for flood control, water conservation, hydroelectric power, and recreation. The dam is operated and maintained by the International Boundary and Water Commission (IBWC); an international body composed of the United States Section and the Mexican Section.

C. The Operations and Maintenance of the dam requires a mobile crane to move various heavy structures such as bulk heads, Penstock gates and trash racks. The crane is also used in man lift operations over the edge of the bridge on both the downstream and upstream sides of the dam; as well as through a 4-foot slot located along the center line axis of the dam.

D. The last crane used at the dam for many years was a Grove TM 9120 mobile truck crane equipped with telescopic beam type outriggers that are removable for highway travel. The superstructure was capable of 360-degree rotation in either direction. The Crane general description and a summary of its technical specifications are included in Appendix Number I for reference.

E. The said Grove TM 9120 had the capability to meet all the operational and maintenance requirements at the dam. However, there was some concern regarding the loads exerted on the bridge structure during some crane operations. During past crane operations 4’x4’x1” steel plates are used under each foot of the outrigger to disseminate loading on the deck.

F. This solicitation is for a TMS9000-2 Grove Crane or approved equivalent suitable to handle the loads tabulated in Article III “Scope of Supply”. For the same technical capabilities and price range, preference may be given to the crane with the lowest dead weight.

III. SCOPE OF SUPPLY:

The vendor is required to supply:

1. One TMS9000-2 Grove Cane or approved equivalent including a complete set of counterweights, counterweight slings and miscellaneous standard equipment.

2. Complete rigging equipment to meet the requirements for lifting each of the items listed items 1 to 6 and the table shown in Article A hereof “Main Performance Requirements”; including but not limited to, Wire Rope Slings, Hooks, Shackles, Eye Bolts, Hoist Rings and Turnbuckles.

3. All the standard hook blocks plus one additional single sheave snatch block.

4. One spare tire for each type and/ or size of tire on the Mobile crane carrier.

5. One complete set of steel outrigger pads.

6. Training/ Orientation of two qualified crane operators in the operation of the new crane.

7. Two hard copies and one disc of complete sets of operations, maintenance and parts manuals.

The crane shall meet the following requirements:

A. Main Performance Requirements: The crane shall be equipped to provide the full range of loads lifting and moving activities at Amistad Dam and Power Plant. The crane shall travel and maneuver along the Dam bridge. There are two lanes; one outbound and one inbound. Each lane is 13’ 9” wide, separated by an island that is 6’ 6” wide. The main requirements are as follows:

1. Lift a metal stop log 52.3’ X 4’ X 1.75; weighing 23,000 pounds from a point below the deck and travel with the stop log along the roadway on the top of the dam and off the roadway to the warehouse.

2. Lift a bulk head gate 14.3’ X 24.6’ X 1.6’ weighing 38,000 pounds from a point below the deck and travel with the bulk head gate along the bridge way and off the roadway to the warehouse.

3. Lift a Penstock gate 16.25’ X 16.3’ X 2’ weighing 54,700 pounds from a point below the deck and travel with the gate along the bridge way and off the roadway to the warehouse.

4. Lift a man basket with two men and up to 200 pounds of tools and extend it over the upstream or downstream side of the dam (up to 80 feet from the centerline of the dam roadway).

5. The Crane hoist rope shall be of sufficient length to reach all underdeck areas as listed below. The deck is at elevation 1152.30 Ft whereas the bottom of the trash rack is at elevation 925.00 Ft; a difference of 227.3 feet at 12:1 slope.

6. The following table contains a summary of the main operation schedule for the mobile crane:
