Questions & Answers / Clarifications

This document provides answers to questions raised during a site visit for the Hume Basin IRSC project, clarifying details related to the solicitation.

• Funding & Optional Units: Optional units are not likely to be funded, with priority given to thinning from below. The project is funded from a single pot and should not exceed two years. Funding for mandatory items is sufficient, and any shortfall would result in an Anti-Deficiency claim.
• Work Order: Items are to be completed in order: 1, 2, 3, and then 4.
• Marking & Material: Hazard and sanitation trees in HT units are marked for removal. Other harvest trees use DxP designation. Unit boundaries are virtual, except for private property lines marked with orange paint. Sub-merchantable material (0-9.9 inches) will generally be left standing.
• Volume & Estimates: The 3.5 million board feet is for mandatory work only. Cull material estimation used a Sample Tree (STR) method. Error margins for timber cruises were 30-40% for Thin/Thin from below units and 200% for Hazard Tree strata.
• Optional Work Prioritization: Bidding for optional work should assume units with excess of 40 tons per acre (after initial cut/skid/deck/haul) will be prioritized.
• Timber Subject to Approval (TSA): Refers to cull logs and excess material not in the mandatory haul. Bidders can negotiate pricing for TSA later if not included in the initial proposal.
• Cabin Units: There are 46 cabins within the unit. Water is shut off in winter, but power remains on. Access is year-round but can be difficult in winter. A map will be provided upon award, but contractors are encouraged to walk the site.
• Roads: Tenmile Road is open year-round but can be difficult in winter. Road closures by the contractor should not exceed 30 minutes. Caltrans manages Hume Lake Road. Roads and bridges are suitable for heavy machinery.
• Archeology: Archeological sites in the project area are of moderate to low significance. For larger sites, coordination with the COR and District Archeologist is required for logging plans.

Clarifies details regarding funding, work order, material handling, volume estimates, prioritization of optional work, and specific site conditions (cabins, roads, archeology), which may influence bidder proposals and execution plans.

Statement of Work (SOW) / Performance Work Statement (PWS)

To improve or maintain forest health, heterogeneity, and resiliency; maintain and improve wildlife habitat; and reduce fuels and restore fire into the ecosystem by thinning from below and sanitizing trees in overstocked plantations, particularly in the upper Tenmile and Bearskin Creek drainages. The goal is to reduce risk from beetle attack and stress from increased inter-tree competition.

This document outlines several work items, primarily focused on tree cutting and removal, and associated tasks:

• Mandatory Item 1 & 1.1 (Thin from Below/Sanitize Plantations): Remove live and dead conifer trees up to 20 inches diameter at breast height (DBH) and dead trees of any size that meet sanitation criteria. This includes sanitizing trees within 100 feet of specific access roads (Tenmile and Huckleberry) based on hazard criteria. It also involves hand piling or mechanical piling of dead and down fire or insect-killed trees. Specific requirements include leaving 4 snags per acre and retaining an average of 4 largest down logs per acre. Protection of paved roads with protective pads and video recording prior to operations is mandatory.

• Mandatory Item 2 & 2.1 (Roadside Hazard/Sanitation Trees): Cut and remove live and dead trees within 100 feet of Tenmile Road (13S09) and Huckleberry Road (13S02, 13S52, 13S49) that meet high and moderate hazard criteria. Stumps are to be cut to 6 inches height for scenic integrity along these roads. Hazard trees in Special Management Zones (SMZs) are to be hand-felled away from trails and roads.

• Optional Item 3 (Thin from Below/Sanitize Plantations): Similar to Mandatory Item 1, but covers a larger acreage. Includes cutting and removing trees meeting minimum specifications, piling debris, leaving snags and down logs, and protecting leave trees.

• Optional Item 4 (Piling of Material in Units): Piling of remaining material over 10 inches DBH and 10 feet long, resulting in an average fuel loading of 10 tons per acre. Piles are to be constructed in a "teepee" or pile-shape, at least 6 feet tall, with a 3-foot fire line cleared to mineral soil. Specific limitations on pile location relative to private property and live trees are included.

• Optional Item 5 (Biomass Removal): Subsidized removal of surplus or excess timber products by rail. Specific requirements for debarking logs transported outside of ecological bug/pest zones are detailed.

• Protection of leave trees is a high priority; no more than four damaged trees per acre are permitted. Exceeding this limit incurs a $50.00 charge per additional damaged tree.

• Work quality is assessed through informal visual inspections and formal verification plots. Minimum Acceptable Quality Levels (AQLs) are specified for each item (e.g., 90% for Item 1, 100% for Item 1.1).

• Specific procedures for inspection, including fixed radius plots and mechanical piling inspections, are outlined.

• Unsatisfactory performance (below 85% AQL) can lead to rework orders, reduced payment, or contract termination.
