Snohomish County Airport (the Airport) awarded the Terminal Apron Reconstruction (PW-24-0361SB, Motion 25-0780) to KLB Construction, LLC (KLB) on 5/7/2025 for $7,319,097.61 inc. applicable sales tax.
In August 2026, KLB encountered soils that appeared to be contaminated in an area that was required to be excavated to proceed with the planned construction, which required the soils to be removed.
The Airport contracted with GeoEngineers to sample and test soils in the project area, which confirmed that the soil contained moderate levels of hydrocarbons, which Republic Services agreed to accept this contaminated material at their disposal facility Roosevelt Regional MSW Landfill.
Change Order 2, in the amount of $690,116.70 (inc. sales tax), accounts for the additional costs for handling and disposing of the contaminated material.
A prior Change Order 1 was executed in May of 2026 for $88,335.20 for unrelated additional required paving work.
The Airport seeks authorization for the Executive to execute this Change Order 2 with KLB in the amount of $690,116.70.
