Key points: • Site‑walk inspection scheduled for August 4, 2026 (non‑mandatory). • Questions must be submitted by August 14, 2026. • Bid opening on August 19, 2026 (9:00‑11:00 AM) at Pearblossom Project Headquarters. • Completion deadlines: two buildings by Nov 30, 2026; remaining two by Apr 30, 2027. • Contractor must hold California B‑class license with C‑22 classification (or subcontract to C‑22).

Budget estimate

$350,000 – $560,000

The solicitation lists an estimated cost range of $3.5 M to $4.0 M, which represents the contractor’s potential earnings (excluding profit). Assuming a typical contractor margin of 10‑15 % on a $3.75 M average, the expected net revenue would be roughly $375 k–$560 k. Therefore, the budget estimate for the client is in the low‑to‑mid‑hundreds‑of‑thousands range, influenced by the scope’s complexity, hazardous‑material handling, and the required safety and prevailing‑wage compliance.
