Bayside Environmental Construction (Bayside) was proud to serve as a key team member in the U.S. Navy’s innovative pilot project to address PFAS contamination at the former Naval Air Station Alameda. The effort—highlighted in the July–August 2025 issue of The Military Engineer in an article titled “Mitigating PFAS at Naval Air Station Alameda”—focused on the design, installation, and testing of a 720-ft in situ permeable adsorptive barrier using colloidal-activated carbon (CAC).

The CAC barrier represents a sustainable and cost-effective method to prevent PFAS from entering the Oakland Inner Harbor, protecting nearby ecosystems while advancing remediation technology for future applications.

NAVFAC BRAC PMO West awarded a task order to Bayside Engineering Construction, Inc. (Bayside) for colloidal activated carbon (CAC) treatment of per-and polyfluoroalkyl substances (PFAS) at Installation Restoration (IR) Site 14 at Alameda Point, Alameda, California (Site). Bayside collaborated with APTIM, Inc. on this project.

Bayside provides Specialized Inspection Property Analysis (SIPA) and Comprehensive Repair Surveys (CRS) nationwide for the U.S. Department of Housing and Urban Development (HUD). These inspections identify repairs needed to meet HUD’s housing standards and support property assessments for purchase or rehab. Bayside also conducts Phase II Environmental Site Assessments (ESAs) to evaluate potential contamination at HUD sites, led by licensed geologists and engineers across all U.S. states and territories.

Bayside EC has been awarded a NAVFAC Southwest IDIQ contract to perform sewer and wet well maintenance, repair, and inspection services across San Diego Navy sites.

Bayside completed full site clearance for homes damaged by the Palisades Fire, including asbestos sampling and debris removal under EPIC-LA permit requirements.

This Time Critical Removal Action (TCRA) at NOLF included transportation and offsite disposal of non- radiologically impacted non-RCRA waste, site grading, radiological surveys, soil chemical sampling, and analysis under the stockpiled materials.

The primary objectives of the CMW are to mitigate for the loss of wetlands and associated habitats as part of the remedial measures at Site 1 and to increase the areal extent and function of wetlands on the perimeter of San Francisco Bay that were lost due to historical development.

Bayside installed concrete walkways and storefront facade at UCSD facility.

Bayside has been awarded several professional services projects by a variety of prime contractors for various Caltrans Districts.

Bayside employees performed literature reviews and archival records searches, conducted biological surveys and habitat assessments for special status species, focused surveys , and delineated wetlands and waters within the study area.

Bayside support included sampling munitions constituents, excavation and mechanical screening of the soil, digital geophysical mapping of the excavated areas, subsurface clearance of identified targets, and backfill of excavated areas with screened soil.

Bayside conducted a roughly 35-acre delineation of wetlands and waterways in Los Angeles County, California, on Santa Catalina Island.

Bayside provides an array of biological and regulatory permitting services.

Bayside associates provided quality assurance, specification compliance and design support for the construction of road improvements over a 1.71 mile road alignment.

Bayside supported the demolition of an overhead steel conveyor system including mezzanines, drying ovens and bracing and support beams up to the Paint Shop ceiling.

Bayside provided HR KRAMER with Quality Control, Site Safety Health oversight, Analytical, and Geotechnical analysis for a parcel of commercially leased property. Bayside’s engineer and geologist worked with subcontractors and professional engineers to develop a parcel of land into a commercially approved Recreational Vehicle and Boat storage parking lot.

Construction consists of beam and plate shoring to excavate down to 20-feet below the ground surface, the placement of a 7,000-gallon tank with a wet well, riser pipes, and forced main sewer instrumentation.

Bayside completed over 200 COVID-19 disinfection task orders at 13 Navy and Marine Corps bases under NAVFAC Southwest, supporting military readiness and safety.

Bayside supported continued operations and maintenance (O&M)/long-term monitoring (LTM) of the existing groundwater remedies, including the extraction and conveyance system, as documented in each site’s respective Record of Decision (ROD).
