Description

This contract awarded by Snohomish County (WA) calls for the supply of refurbished cartridge‑type storm‑water filters for the county’s road‑maintenance storm‑water system. The county requires a variety of 18‑inch and 27‑inch cartridge filters, each meeting specific material and performance specifications (LLDPE/ABS housings, welded‑wire screens, specific hydraulic loading limits, and defined media types such as perlite, CSF, metal Rx, zeolite, GAC, ZPG). The awardee, Contech Engineered Solutions, will deliver the filters to the county’s facilities and accept payment via the county’s purchasing (P‑Card) system. The contract is a one‑year, firm‑unit‑price agreement with the possibility of up to four additional one‑year renewals.

Contract value

$48,000

The bid tabulation shows a subtotal of $43,650 plus 9 % sales tax ($3,753.90) for a grand total of $47,403.90. The invitation‑to‑bid document lists a printed total of $47,578.50, suggesting a similar order of magnitude. No other line‑item totals exceed $50 K, and the contract is limited to a single year. Therefore a reasonable ballpark for the contract’s value is roughly $48 K (≈ $47‑$48 K). Factors influencing this estimate include the unit prices per cartridge ($110‑$130), the quantities required (≈ 480 units total), and the inclusion of sales tax.
