About this file
This Performance Work Statement (PWS) details a procurement request by the USDA Agricultural Research Service for constructing a reinforced concrete water crossing and drop structure at the Conservation and Production Research Laboratory in Bushland, Texas. The project requires building a 20-foot wide by 60-foot long improved ford with six-inch thick steel-reinforced concrete, including a 20-foot by 8-foot water spreading drop structure with a 1-foot vertical drop at a 1:2 slope to reduce water erosion.
The technical specifications call for ½-inch rebar placed on 1-foot centers, concrete with 4,000 psi compressive strength, and a flat bottom with 20-foot transitions sloping upward to meet existing roadway surfaces. The project is located at geographic coordinates 35°10'37"N 102°05'32"W, with the primary purpose of enabling all-weather access to the 1,500-acre federal property and preventing erosion of the existing unimproved ford. The required delivery date is 30 July 2024, and the procurement method involves soliciting bids from local vendors.

Summary of Procurement Request for a Purchase
Requirement Name: Concrete water crossing and drop structure
Suggested Method of Procurement: bids from local vendors

Prior Contract: N/A
Required Delivery Date: 1 through 30 July 2025
Performance Work Statement / Statement of Work:
General Information:
Background and Purpose: The USDA, Agricultural Research Service (USDA-ARS) requires an improved ford (low water crossing) at 35°10'37"N 102°05'32"W to enable all-weather access to federal property and goods and to prevent erosion of the existing unimproved ford. The Conservation and Production Research Laboratory (CPRL) conducts field crop research. The purpose of the request is to replace an existing unimproved ford with a reinforced concrete improved ford at an entrance to the property from County Road 34 (see Figure 1). This procurement action is to replace the unimproved ford, which is badly eroding to the point of stopping traffic from entering and exiting the property, with a reinforced concrete ford. Due to the size of the laboratory grounds (1,500 acres), a viable all-weather entrance from County Road 34 is essential to allow entrance and egress, which can become a safety issue if a wildfire occurs. To protect assets at the Conservation and Production Research Laboratory (CPRL), 2300 Experiment Station Road, Bushland, Texas 79012, it is necessary to purchase this improved concrete ford.

Contractor Requirements:
The requirement is excavation of soil, placement of steel reinforcing bars, and placement of concrete according to Figure 1 and product specifications.
Product Specifications:
1. Improved reinforced concrete ford width of 20 feet.
2. Improved ford length in direction of travel of 60 feet.
3. Reinforced concrete to be six inches thick with ½-inch rebar on 1-foot centers throughout and compressive strength of 4,000 psi.
4. Improved ford flat bottom of 20 feet length and level in direction of travel, with 20-foot transitions sloping upward to roadway on either side in direction of travel.
5. Water spreading drop structure with dimensions of 20 feet by 8 feet in plan view (Fig.
1) and sloping drop of 1 foot at 1:2 slope on downstream side of ford bottom to a flat apron to reduce erosive energy of water flows per Figure 2, also made with reinforced concrete per item 3.
6. Placement such that transition to existing roadway and surrounding terrain is smooth.
