PART 2 – WORK REQUIREMENTS

2.0 Period of Performance

The Government considers the tasks above be completed within 60 calendar days after contract award has been issued. The Contractor shall provide all labor, management, transportation, equipment, supplies, materials, etc. necessary to perform these activities. Scope is added in this revision to include insulation after BGNDRF staff replace a water meter. This work may be done later in 2025, depending on when the water meter will be delivered.

2.1 Repair Tasks

The following summary list of activities/tasks to repair the Piping Insulation as follows:

· Place and re-attach existing heat trace to piping for optimum protection of the piping system.

· Furnish and install new pipe insulation and aluminum jacketing as required by Reclamation specifications (Section 1.3) and drawings (can be provided if requested). Table 1 shows the approximate lengths for each section in need of repair. Appendix B includes pictures of each section in need of repair.

· Insulate sight glass, motorized valve (MOV), and various piping.

· Insulation on sight glasses must allow for visualization of water level in hydro-pneumatic tanks and not interfere with level measurement.

· Clean up and removal of debris from the work site.

Appendix B - Pictures of BGNDRF Piping Needing Insulation All pictures were taken on September 12, 2024.

Photo B-1: Stallberg Well (Well 4). The 4-inch (right side) well piping is reduced to 3-inch and the full length of exposed piping and fittings is approximately 3 ft.

Photo B-1a: Stallberg Well (Well 4). The 4-inch water meter will be replaced by BGNDRF staff, and the area will need to be reinsulated.

Photo B-2: Wellfield bypass to evaporation ponds. All piping and fittings are 4-inch and approximately 6-ft of piping is exposed. Note: BGNDRF staff will raise pressure gauge by 4” prior to work starting.

Photo B-3: Cooling Tower Piping System. Pump 1 (in foreground) piping is covered with temporary foil and insulation. The piping from left to right transitions from 2-inch to 1.5-inch to 3-inch diameter and spans approximately 5-ft.

Photo B-4: Cooling Tower Piping System. Pump 2 (in foreground) piping is bare. The piping from left to right transitions from 4-inch to 3-inch to 1.5-inch diameter and spans approximately 11-ft.

Photo B-5: Cooling Tower Piping System. Motorized Valve (MOV) for Well 1 supply. The MOV is 6-inch and is approximately 1.5-ft long.

Photo B-6: Hydrotank Sight Glass Level Indicator. Tank 2B (left) picture shows temporary foam insulation that needs to be replaced with approximately 5.5-ft of jacketed insulation (previous jacketed insulation was removed because it was affecting operations. Tank 3A (right) picture shows a working jacketed insulation.

Photo B-7: Test Pad 8 Source Water Feed. The valve and piping are 2-inch and the exposed length is approximately 1-ft.
