VERTEX was retained to assist in the redevelopment of this early 1900’s industrial property in the Central Platte Valley area of Denver, Colorado. The Central Platte Valley area was historically occupied by heavy industrial use and a large rail yard. The site was historically occupied by food manufacturing/bottling companies until the mid-1970s and then occupied by various industrial/commercial businesses until 2012, when the building was finally vacated. Several underground storage tanks (USTs) were previously located on-site and one UST was still in place.
The project included the completion of an ASTM Phase I Environmental Site Assessment of the building by VERTEX, which revealed several Recognized Environmental Conditions (RECs), including the historical operations of the facility, USTs, suspect asbestos containing materials (ACMs), potential lead-based paint and other various hazardous/regulated materials still present in the building.
VERTEX conducted a Phase II Limited Subsurface Investigation (LSI) at the facility that included the installation of soil borings and groundwater monitoring wells to assess for potential residual impacts from historical site operations. Various concentrations of contaminants of concerns were identified during the investigation, relating to the historical site use. As a result, VERTEX prepared a Materials Management Plan for use during the redevelopment activities to ensure proper management, characterization and disposal of on-site soil and groundwater in accordance with local and state regulations.
Concurrent to the Phase II LSI, VERTEX conducted a Hazardous Material Survey of the property which revealed the presence of several friable ACMs that required abatement prior to demolition of the site structure including an extensive abatement that occurred in the boiler room of the facility. VERTEX managed and oversaw the asbestos abatement activities and characterized the regulated/hazardous materials on-site for the client for removal prior to demolition of the site structures.
VERTEX oversaw the removal of the abandoned UST on-site and collected confirmation soil samples to determine potential residual impacts from the UST. Additionally, VERTEX oversaw and managed the soil excavation and disposal activities on-site which included removal of approximately 10 feet of impacted fill material from across the site, soil characterization for off-site reuse and determining potential construction dewatering efforts in order to comply with state discharge regulations.
The project was completed on-time and under budget. VERTEX’s findings and guidance throughout the project provided the client with the ability to navigate complex on-site environmental issues, achieve compliance with local, state and federal regulations and maintain the project timeline.
