OUR PORTFOLIO

Planned and managed the procurement, permit acquisition, design, construction, and commissioning of the over $ 85 million 30 – acre Area 5 landfill cell expansion. Led the construction management team that oversaw the development of this first subtitle D landfill cell in Washington State.

VIKEK, for landfill closure, site redevelopment design and construction  of residential buildings, and permits sought from the City of Everett, and Department of Ecology by the Owner, completed landfill gas and risk assessment, and design and oversight of the construction of the landfill gas collection and control  system. Vikek team also provided testimony at the Pollution Controls Hearings Board. ​

The OB3 wastewater lagoon has a 100-mil high-density polyethylene (HDPE) geomembrane floating cover (“cover”) installed in 2018. The lagoon is a single cell that is approximately 1,350’ long by 225’ wide. Three facilities utilize the lagoon. The lagoon operates 365 days per year, so the lagoon cannot easily be taken offline. 

To support mitigation of cover deficiencies and acquisition of permits, VIKEK provided lagoon cover geomembrane integrity and leakage assessment. Specific activities included evaluating the floating cover leakage mitigation options, remedial construction observation, and quality assurance.

Engaged to managed a team responsible for developing a first-of-its kind Line of Business Plan (LOBp), by conducting a comprehensive review of the existing King County’s solid waste management system, including external stakeholder requirements and to evaluate and identify options for enhancing and improving these systems to assist the County’s planning efforts in light of immediate and future regional solid waste management challenges, including the upcoming exhaustion of landfill capacity by 2027 and potential closure of the regional landfill.

The existing solid waste facility was designed and constructed in the late-1970s. The County’s population is projected to increase by 32% by 2040, which will have a significant impact on service delivery and customer service expectations. Requirements regarding safety, service levels, sustainability, fees, and regulations developed through this project will need to reflect the County’s changing demographics, a continually evolving climate, a dynamic global economy, and modern technological capabilities. 

VIKEK, under contract with the County, is completing assessment of alternative replacement sites and associated recycling and transfer facility conceptual design plans for a new facility that will meet current solid waste management level of service needs.

The Roseburg Landfill began receiving waste in 1932, and from 1932 until 1975 it was privately operated as a burning dump. In the late 1960s, burning operations ceased. Douglas County (“County”) has operated the site since 1975, and currently receives an annual average of 80,000 and 20,000 tons per year of municipal solid waste (MSW) and construction/demolishment waste (CDW) respectively. 

VIKEK under a prime contract is completing assessment of the landfill gas collection and control system and providing implementation support for improvements necessary to achieve operational performance targets pursuant to Oregon State and ownership requirements.

Planned and managed the procurement, permit acquisition, design and construction of the over $80 million Cedar Hills Area 4 phased Closure. This was the first structured and permitted phased landfill closure in King County that employed a new strategy of not closing the top deck, and enabled the agency to optimize capacity and extend the life of the landfill. Project tasks included – alternate cover capping systems, leachate management system modifications, evaluation of closure/post-closure plans from a constructability and cost-effectiveness perspective, performance of a field test pit program to determine the waste boundary and thickness of the existing intermediate cover, oversight over the construction management consultant team.

Designed and managed construction of leachate extraction wells, 1.5 MG capacity HDPE – lined contaminated stormwater lagoons, and 250 GPM pump station at the Hobart Landfill in King County. Planned, and managed the permit acquisition, design, and construction of the final cap of the 75 – acre Hobart Landfill in Washington State. Facilities constructed included slurry containment wall, pump stations, landfill gas flare stations, groundwater wells, leachate, and stormwater control systems. Project cost was over $ 50 million.
