LACO provided material testing and geotechnical support for the construction of a new 49,000 square foot store and 200,000 square feet of new parking lot in Eureka, California. Phase 1 consists of site improvements including MSE retaining wall, stormwater detention/infiltration swale, underground utilities, and general parking lot improvements for the new store in Humboldt County, CA.
The site had construction challenges due to fine-grained soils, perched groundwater and undocumented fill soils. LACO worked in a proactive role with the Owner and Contractor to create solutions to these ongoing concerns to keep construction progressing, while supporting quality results. Our project team worked closely with the Safeway construction management staff, the general contractor, and their subcontractors to meet the following project requirements:
- County right of way utility improvements compaction testing
- Site grading, compaction testing, parking lot improvements
- Hilfiker retaining wall compaction testing and laboratory analysis of backfill materials
- Geotechnical exploration for compliance with project soils report
- Geotechnical recommendations for as found site conditions
- Investigation of detention/infiltration swale capacity per project plans
- Structural concrete placement, sampling, and rebar placement
