On-site work must fit within a seven-calendar-day facility shutdown and may require around-the-clock work. - OEMs and products: No OEM-manufactured products or product part numbers are specified; this is primarily a services opportunity. CastleBranch is named for contractor background screening, not as a pipe-cleaning OEM. - Estimated value: Approximately $50,000–$150,000; the solicitation does not state a value.
