ENVIRONMENTAL DUE DILIGENCE PROJECT HIGHLIGHTS

PROJECT 1: Critical Evaluation of Asbestos Abatement Bids for Two Midwestern Power Generation Plants

Applying industry-specific knowledge of power plants, Landmark completed a critical review of abatement bids and developed a comprehensive abatement cost estimate, resulting in substantial savings to project costs. 

Landmark developed specifications, solicited and evaluated bids for abatement of asbestos-containing materials (ACM) at the two 100-year old Power Plant Sites in Chicago, Illinois. This project encompassed significant demolition activities, including the abatement of ACM and other Regulated Building Materials (RBMs). The project also included the recovery of equipment and scrap metals, with the client anticipating that the asset value of the plants would exceed the cost of RBM abatement and demolition.

Based on previous Hazardous Materials Assessment Surveys, Landmark developed a Technical Specification and ACM Abatement Bid Sheet, which was provided to several General Contractors. The Bid Form included a net price to be paid by the Bidders for the rights to the assets along with the obligation of completing the work described in this Technical Specification. The design approach to the project accommodated the discovery and management of unforeseen conditions so that project workflows would not be interrupted.

 

During the review of the bids, Landmark identified certain items where potential data gaps in existing survey reports, potential variability in the assumptions made by the bidders in completing the bids, and uncertainties regarding site conditions could result in significant impacts on opinions of probable abatement costs. Using the budgetary numbers provided by various bidders and refining those numbers based on relevant industry experience, Landmark prepared revised abatement cost estimates for each site, resulting in substantial potential savings to the overall project based on clarification of bids with contingency and “to be defined” conceptual costs.

PROJECT 2: Demolition Management of a Large Major Manufacturing Site

Landmark safely completed a seven-year decommissioning and demolition of a major aerospace manufacturing site during the transfer of the property from Brownfield to Greenfield Redevelopment.

Landmark successfully designed and managed the environmental decontamination and demolition of the one million square foot industrial building on the 45-acre former Hamilton Sundstrand Denver Metal Works facility. The facility included multiple buildings that began operations in the 1950s, was decommissioned in 2003 and 2004, and demolished in 2007 and 2008. Corrective action plan investigations continued at this site until 2019.

Manufacturing processes in this facility included machining, welding, electroplating, painting, heat-treating, nondestructive testing, and waste treatment.

 

Landmark identified and managed contaminated soils and successfully developed the first Soil Characterization Management Plan in Colorado managed under dual regulatory jurisdictions. Our programs for the site were submitted during the promulgation of new applicable regulations, and yet our plans were accepted by the regulators with only minor comments.

Landmark provided turnkey services during the decommissioning phase and performed extensive industrial hygiene monitoring throughout the project for asbestos, metals, polychlorinated biphenyl (PCBs), and other chemicals during the demolition phase. Landmark and our affiliated toxicologists performed a human health risk assessment for PCBs. Our staff also conducted hazardous waste evaluations and identified proper treatment and disposal methods.

The property was developed in consortium with former owners, Brownfield and Greenfield developers, municipalities, and state health regulators. This project was completed on time and within budget contingencies.
