PART 1 – SUMMARY OF WORK

1.1 DESCRIPTION OF WORK

A. Contractor will clean & inspect four water tanks located within Crater Lake National

Park(CRLA or Park), Klamath County, Oregon. Park water storage tanks need to be cleaned and inspected to document the normal buildup of sediment and identify any equipment deterioration that may require repairs in the future.

Tank Locations and Sizes:

• One each, 150,000 gallon tank at park headquarters (Munson)

• Two each, 100,00 gallon tanks are at Mazama

• One each, 185,00 gallon tank at Garfield Reservoir

• Tanks at headquarters and Mazama are accessible by service roads.

• The tank at Garfield is accessible only by a hiking trail.

• Refer to map as Figure 1 at end of this document.

BASE WORK. Inspect and clean tank walls, floors, and remove sediment from the four tanks identified/listed above.

B. OPTIONAL REPAIR WORK. The Government anticipates that the contractor team may find repair work needed. Contractor shall submit a request for change order of the repair work that the Contracting Officer may consider. The Contracting Officer may proceed with incorporating the additional repair work as a contract modification by agreement of the parties. The request for change order pricing shall be based on the same rates/pricing structure as used in Contractor’s original quote for the award of the purchase order.

Contracting Officer may require contractor to submit a price breakdown for the change order request for a modification that supports the lump sum price requested, at a minimum, to view labor categories with job titles indicating hourly rates and number of hours for each.

C. WRITTEN DIGITAL REPORTS. The contractor will provide written and digital reports to the park once work has been completed. Sediment that needs to be removed will be the responsibility of the contractor and may or may not be deposited at location of removal depending on the contents of the sediment. Any Costic sediment will require the contractor to remove it off-site following all Federal, State and Local regulation for debris removal.

PART 5 – DELIVERABLES PRIOR TO START OF WORK

1. Contractor’s written designation of their Project Lead/Project Manager, the primary point of contact for the COR and must be onsite at all times work is occurring. Email contact info

(name, title, phone, email) to the Contracting Officer and COR.

2. Project Schedule - Submit a baseline schedule with start date before commencement of onsite work. The period of performance is short, 45 days after award, so Contractor’s project schedule can focus on only the major milestones/key tasks/key phases of work through being ready for inspection, and contract completion date. Government anticipates period of performance to be from September 14 – October 30, 2026. Weather may affect total completion to which a seasonal shutdown period may need to go into effect pausing the project during winter months due to snowfall, so the priority is to complete work on the

Garfield tank first.
