VERTEX was retained to assist in the redevelopment of this early 1900s commercial and industrial property in the Central Platte Valley area of Denver, Colorado. The area was historically occupied by heavy industrial use, rail yard, commercial dry cleaners, printing facilities, machine shops, and other operations of environmental concern. The site was historically occupied by printing facilities, an asbestos factory, machine shops, and a chemical laboratory.
The project included the completion of an ASTM Phase I Environmental Site Assessment, a Phase II Limited Subsurface Investigation, asbestos abatement, construction support consulting, and permanent groundwater treatment system design.
Based on the results of the Phase II LSI, 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. VERTEX oversaw and managed the soil excavation and disposal activities on-site which included the removal of impacted coal-based fill material.
Further, due to the presence of contaminated groundwater at concentrations exceeding regulatory standards and the need for short-term dewatering during construction and long-term foundation dewatering, VERTEX managed and oversaw the short-term dewatering activities during construction and designed, procured, and installed a state-of-the-art, fully automated groundwater treatment system on-site that included the use of oxidation, ion exchange media, granular activated carbon and mechanical filtration for use long term in order to comply with state discharge regulations.
The project was completed on-time and under budget. VERTEX’s consulting and guidance throughout the project provided the client with the ability to navigate complex on-site environmental issues, achieve and maintain compliance with local, state, and federal regulations, and maintain the project timeline.
