Confluence Park and It’s Journey

The Confluence Park Soil and Water Remediation project has hit a couple of snags throughout their journey to completion. One of those being the discovery of coal tar in May 2015 causing serious issues since coal tar is known to contain human carcinogens that are toxic to aquatic life. This prompted the collaboration with ESA. In order remove the coal tar they had to dewater the site and, once dry, remove the contamination, taking on the added risk of the environmental impacts of the project.

Earth Services & Abatement (ESA) Completes Water and Coal Tar Remediation at Confluence Park

Confluence Park was created in 1974, after a public- private partnership comprised of the City and County of Denver and the Greenway Foundation formed to reclaim the South Platte River from a dumping ground to a recreational area. Since the official dedication in September of 1975, the area has continued to grow through several additions, the latest of which includes the visioning of the Confluence Park 2013 Master Plan. In May of 2015, coal tar was discovered, which shut down the project for 15 months. ESA was called upon to dewater the site and, once dry, remove the coal tar contamination, taking on the added risk of the environmental impacts of the project. View the full story... read more

Owners of an Abandoned Sugar Factory in Colorado Save Millions in Demo Work

Open-air demolition process reduces price tag by more than 50% For five years, Schafer conducted extensive research and worked a complex series of proposals with the Colorado Dept. of Public Health and Environment (CDPHE). Several abatement and demolition firms bid on the project, intending to use traditional methods, fully containing the structure in poly sheeting and then demolishing the structures after all asbestos had been removed. The costs were astronomical, ranging from $7.3 million to $11 million. Earth Services & Abatement (ESA) proposed an alternate plan that might, if successful, save Amalgamated millions of dollars. Central to the problem was the mill building. According to Rod Schafer, the building was like a city within itself. “It housed its own powerplant, huge boilers and rusted machinery. The upper floors were collapsing. Engineers and the local fire department assessed the building, and calculated what would be necessary to rebuild parts of the structure to make it sound enough to proceed with the asbestos abatement,” Schafer said. The customary method for abating the mill building would have been first to enclose it, abate the asbestos and then demolish the building. However, there were tremendous safety concerns related to abating the main mill structure. Walls were collapsing, floors had dangerous penetrations and handrails were mangled and broken. In short: it was unsafe to abate. ESA thought there must be a safer way that would also be more cost-effective, so ESA teamed up with Schafer and CDPHE to devise a safer process that would cut costs by several million dollars. ESA had two main challenges: get the local landfill to approve a one-time asbestos... read more

Ovid’s Metamorphosis: How open-air demolition halved costs for a sugar factory project

The small town of Ovid rests in the far northeast corner of Colorado near the Nebraska border. While its modern amenities are limited to a couple of restaurants, a grocery, and a gas station, the town retains a significant historical landmark: the gleaming white storage silos containing beet sugar from what once was the Great Western (GW) Sugar Company’s finest factory. Built during the booming sugar economy of the early 1900s, Ovid’s huge GW factory was built with coal, steam, and mules. The town incorporated in 1925 during the factory’s construction, and by 1940 had grown to a resident population of 650—twice the town’s current population. Unfortunately, Colorado’s sugar economy died off with the expiration of the Sugar Act in 1974, and the factory closed two years later. By September 2006, the entire domestic beet-sugar industry had become grower-owned. Amalgamated Sugar, a cooperative of sugar beet farmers, bought the Ovid property in 2002. It had been abandoned except for the warehouse and silos, which were still in use. Amalgamated Sugar did not anticipate the liability they had taken on along with the purchase of the property.

Water and Coal Tar Remediation at Confluence Park Complete

Dewatering and Coal Tar Removal A critical part of managing the ebb and flow of the Confluence Park project included the addition of Earth Services & Abatement, Inc. (ESA) to the construction team. ESA has a long history of working with the City and County of Denver, dating back 19 years, and is known for handling complicated remediation projects. ESA was hired to dewater the site and, once dry, remove the coal tar contamination, taking on the added risk of the environmental impacts of the project. “There is always a concern when de-watering a project, especially with high levels of contamination. We took a conservative approach at Confluence Park with three water treatment trailers on-site at one point, running an elaborate dewatering and contamination removal system,” commented Kory Mitchell, President of ESA. The approach paid off, in that out of the 50 million gallons of water treated, none of the water samples were above the regulatory limits for water discharge, according to Mr. Mitchell. He explained that ESA engaged in a value-engineering process with the City as well as the State health department to develop an agreement for discharging the water. He goes on to say that “Discharging water is a sensitive issue because no one wants to take on the responsibility of possibly discharging contaminants back into the river, which is why we put together a top notch team and worked closely with regulators to stay ahead of any complications.” View full article at Mile High... read more

Earth Services and Abatement demos DU Dormitory

The University of Denver has demolished one of the oldest residence buildings it owns. DU discovered renovating the 1960-era Cavalier Apartments would be seven times more expensive than demolishing it, said Spokeswoman Theresa Ahrens. The last round of students moved out in June, and demo work started in November. Ahrens said DU decided to demolish Cavalier, a 30-bed upperclassmen dormitory, after a study by the school found repairs would cost more than $4 million. The demolition by Earth Services and Abatement had a budget of $531,000, Ahrens said. Read full article at... read more

Project Profile: ESA Clears the Way for Stapleton Redevelopment Completion

ESA Teams Up with the Government, Community, and Private Enterprise to Improve the City of Lakewood, CO

Working in collaboration with the Colorado Department of Public Health and Environment, Brinkmann Constructors, SJR Environmental Consulting and Earth Services & Abatement, Inc. transformed a polluted parcel of Lakewood property into a productive new land use.  When one of the first Target stores in the United States opened in Lakewood, Colorado in 1966, the entire neighbourhood turned out to celebrate and shop the big, beautiful space, built by a company that would become one of the world’s largest consumer retailers. Fast-forward 48 years, to 2014. The former neighborhood shopping anchor, now eight years deserted, had been reduced to 168,000 square feet of asbestos-riddled floor space. The Colorado Department of Public Health and Environment (CDPHE) deemed the property a major asbestos spill. Read the full article in Industrial Hygiene... read more

From polluted to productive

An asbestos-riddled former Target store is transformed into a beautiful housing property in Lakewood, Colorado, through a public-private partnership. BY MARY ROSS Brinkmann finally turned to a Commerce City, Colorado, firm that founded its professional reputation on asbestos abatement in 1982. Earth Services & Abatement Inc. (ESA) would tackle the critical job of abating the site of asbestos, demolishing the ramshackle building, and restoring the land’s viability for new use. “The Westlink job was certainly in our wheelhouse, as complicated asbestos abatement with a demolition component is the foundation of our business,” ESA President Kory Mitchell explains. To successfully complete the $1.2 million job, ESA collaborated with the CDPHE and SJR Environmental Consulting to develop an extensive work plan that involved a technical abatement method, Mitchell says. “This project was a perfect fit for our company because it had challenging abatement requirements, challenging demolition needs and a challenging schedule,” Mitchell says. “We have a unique team and all the necessary resources to handle these types of jobs.” ESA owns an entire fleet of heavy equipment, which allows the firm to self-perform all aspects of the job. Because asbestos was present on both sides of the block, ESA had to think outside the box of typical abatement measures. Pioneering a unique approach of demolishing block from inside the structure through the use of an excavator inside the containment, crews accomplished the daunting job of safely abating the structure without the potential of contamination or debris polluting nearby areas.
