Siller & Siller Construction Inc.

Siller & Siller Construction Inc., a small business contractor based in Penn Valley, California, provides heavy equipment procurement and construction services to the U.S. Forest Service as a prime contractor, operating exclusively under total small business set-asides on indefinite delivery contracts and delivery orders for fire suppression and all-hazard incident response operations in the western United States.

Siller & Siller's federal footprint is narrowly concentrated within the Department of Agriculture's Forest Service, which accounts for 100% of recent awards. The National Interagency Fire Center (which oversees the Fire and Aviation Management program) anchors the vendor's largest exposure, with two awards totaling $750 thousand in combined potential value; the Forest Service's Pacific Southwest Region (Region 5) drives volume with seven awards valued at $307 thousand combined. The vendor also holds work with the Forest Service's Rocky Mountain Region (Region 2) and a standalone Forest Service award. All customer relationships derive from the same agency and sub-agency hierarchy.

Siller & Siller holds two indefinite delivery contracts under total small business set-asides, both awarded by the National Interagency Fire Center for heavy equipment procurement supporting Regions 5 and 6. The primary IDC carries a $500 thousand ceiling through June 12, 2028, awarded February 6, 2026; an earlier $250 thousand ceiling contract runs the same completion date, awarded June 12, 2023. Together, these two vehicles carry nine delivery orders valued at $494 thousand. Delivery orders under these IDCs are consistently firm fixed price, short-duration (typically under two months), and concentrated in California locations including Grass Valley, San Bernardino, and Irvine. Procurement is explicitly for Dozers (Types 1–4) and Excavators (Types 1–4) and supporting construction services. Representative recent orders include a $71,523 delivery order from Forest Service Region 2 for construction services in Delta, Colorado (July 29, 2026), a pair of $18,070 calls from Region 5 against the heavy equipment IDC in Grass Valley (July 11, 2026), and a $114,641 Region 5 delivery order for construction services (September 24, 2024).

Activity has grown modestly — one award in 2023, six in 2024, and four through July 2026 — with $494 thousand obligated against $1.2 million in combined potential value. The vendor operates exclusively as a prime, with no subcontract footprint in the source data. All work is classified under NAICS Support Activities for Forestry and PSC Natural Resources/Conservation–Forest-Range Fire Suppression/Presuppression. The vendor's capability portfolio is confined to heavy equipment supply and short-cycle construction support for western-region fire operations; there is no evidence of work outside this narrow scope or customer base.
