Case Studies

A few selected samples from more than 20 years of work.
As an environmental contractor for KCDC, QE2 performed extensive hazardous materials survey work at the multi-structure Western Heights housing project in Knoxville. The work included asbestos testing in preparation for the demolition of many 1950’s era structures, and lead paint and asbestos work for multiple older structures scheduled for renovation. After the completion of the surveys, QE2 assisted the lead Designer in the preparation of asbestos abatement design and demolition documents. The survey work occurred mostly within occupied housing units, and great care was taken to be sensitive to the occupants. The abatement and demolition work also occurred at the site while much of the housing units remained occupied nearby.
The Department of Education (TDE) operates this special educational developmental facility on a campus located off Island Home Boulevard in Knoxville. QE2’s work has included ACM and LBP surveys, full hazardous materials surveys, abatement designs, ACM abatement, and mold and moisture intrusion inspections. QE2 also removed USTs related to a former backup heating oil/generator fuel system.

QE2 and a subcontractor performed emergency abatement of a steam line piping elbow in the Vocational Annex to allow for leak repairs. The task included obtaining subcontractors, coordinating after-hours abatement and clearance, and providing final inspections and reports.

QE2 also performed ACM and LBP Surveys in support of three different SBC projects including ADA Upgrades at the Ward Building, Steam Line and Boiler Replacements at three buildings, and ADA Upgrades in the Auditorium and Cafeteria areas. The tasks included sampling for ACM, testing for LBP with an x-ray fluorescence device, and providing reports with recommendations.

QE2 provided full hazardous materials survey work at Cottage E in support of a later SBC demolition project. The task included sampling for ACM, testing for LBP, inspecting and inventorying PCB-containing transformers and ballasts, hazardous chemicals, checking and testing steam lines in vaults, and mercury-containing bulbs and thermostats. After test results were received, ACM was quantified and abatement cost estimates were developed. QE2 later designed Demolition Plans and Specifications, including Specifications for abatement and engineering drawings, and a Storm Water Pollution Prevention Plan as part of an SBC project. QE2 oversaw demolition, which occurred in 2012-13.

In early 2012, QE2 was tasked to perform mold and moisture intrusion inspection in the TSD Gym Tower, where moisture- and mold-damaged drywall was noted following a renovation project. QE2 inspected the Tower, attended meetings with construction contractors, and provided recommendations for abatement and leak investigations.

QE2 worked on a design project at the former Tennessee State Prison to stabilize and demolish certain single level and multi-level structures of the 100-year old abandoned prison. QE2 tested the soils to facilitate underground storage tank removal and found high levels of polyaromatic hydrocarbons in certain locations around the prison. QE2 determined that the most likely source of these contaminants was onsite disposal of old waste material from the boiler house. Clink from the burning of coal and other fuels had been used to raise the site elevation by several feet in several places within the prison yard. Because future re-development plans were uncertain, QE2 developed and executed a sampling plan to determine the exact location and extent of the contaminated soils, and surveyed that area so the deed restriction would not apply to any larger an area than absolutely necessary. Digging near the historic buildings would potentially compromise their structural stability, so QE2 wrote and helped the State execute a deed restriction to minimize activities and work that could be conducted on the contaminated part of the site, yet did not force the site to Brownfield Hazardous Materials Surveys, Environmental and Abatement Design and Oversight Services University of Tennessee, Knoxville, Carolyn P. Brown Student Center Project July 24, 2014 Quantum Environmental & Engineering Services, LLC Page 8 status. Subsequent work involved designing several building demolitions and structural renovation and repairs to the Cell Blocks and Administration Building. QE2 prepared bid documents and worked with the State to secure contractors for implementing this work in phases over the course of several years.
The Department of Veterans Affairs operates several Veterans Cemeteries across the State of Tennessee. Within the last decade, the existing East Tennessee Veterans Cemetery in Knoxville was reaching critical capacity levels, and the State realized that a new cemetery site had to be readied for the region. A potential site was chosen along the French Broad River in East Knox County and the land was obtained in a land swap agreement with the City of Knoxville. In 2009, QE2 performed the required Phase I Environmental Site Assessment for the property transaction.

As part of the requirements related to the Federal portion of funding for the new site, a National Environmental Policy Act (NEPA) assessment was needed. QE2 performed the work in cooperation with the U.S. and State of Tennessee Departments of Veterans Affairs, the Architects and Designers, STREAM, and specialized plant, animal, wetlands, archaeology and noise subcontractor consultants. The NEPA assessment included community and infrastructure impact studies, interviews with neighbors, geological evaluations, environmental impact studies, and archaeological excavations. The site was determined to be acceptable and all documentation was provided in time to meet critical Federal funding deadlines. The work was completed in 2010 and site construction began soon after. The new East Tennessee Veterans Cemetery was dedicated for service in 2011 and is now a functioning facility.

Recent work at the West Tennessee State Penitentiary in Henning, Tennessee, included hazmat assessment and abatement of four former housing structures and four former guard towers, removal and disposal of the remains of a burned residential structure, removal and disposal of concrete walks and driveways, and transport and disposal of resulting debris.

QE2 aided the State in compiling a presentation for the Tennessee Historical Commission and State Historic Preservation Officer in order to gain permission to demolish the potentially historically valuable structures.

QE2 performed hazardous materials assessments and coordinated abatement at the active correctional complex. QE2 also prepared a cost-effective bid package to facilitate partial demolition by a Contractor and partial demolition by prison inmates. QE2 worked with regulators to obtain the necessary abatement/demolition permit from the State of Tennessee Department of Environment and Conservation (TDEC), Division of Air Pollution Control (APC).

QE2 determined that the total disturbed area was small enough that a Stormwater Pollution Prevention Plan (SWPPP) and Permit was not required and coordinated approval of an on-site disposal area with the TDEC Division of Solid Waste Management (DSWM). At the State’s request, QE2 subcontracted the demolition and disposal activities after awarding the bid. QE2 coordinated off-site disposal of the abated materials, and ensured the Contractor fulfilled manifesting and disposal tickets to document the disposal of abated materials. In order to facilitate the use of inmate labor for demolition of various structures, work was coordinated with the prison’s warden and facility manager. QE2 coordinated with the prison staff to make arrangements for the inmate work crew to accomplish their tasks on schedule so as not to create delays and change orders for the Contractor. The structures were all abated and demolished and the project was finished on budget and on time.

The Carriage House is the security facility at the Tennessee Residence (Governor’s Mansion), and is built in the renovated original carriage house / garage building. QE2 performed several tasks at the Carriage House including an IAQ investigation, radon testing, LBP surveys, and ACM and LBP abatement.

During the summer of 2010, QE2 responded to occupant complaints of IAQ problems at the Carriage House. The task included air sampling for mold, dust, pollen, and dander; surface sampling for mold; inspections for potential moisture intrusion; and measuring temperature, humidity, ultrafine particles, CO, and CO2. While onsite, testing for radon was also performed in the basement, since radon issues had been previously documented at the Governor’s Mansion. (QE2 had designed a radon mitigation system for part of the Governor’s mansion prior ot this work at the carriage house.) The results of the investigations indicated that elevated mold levels existed in the basement, and that the basement air might occasionally enter the occupied spaces. Recommendations included sealing locations where unconditioned basement air may be mixing with upstairs air. The results of the radon testing indicated no elevated concentrations.

In November 2010, QE2 performed a full LBP survey in support of planned renovations to windows and paint at the site. The survey included testing with an x-ray fluorescence device and providing documentation and recommendations.

In the summer of 2011, under QE2’s direction, abatement subcontractors performed LBP and ACM abatement at the Carriage House. QE2 included developing and designing a scope of work, meeting potential subcontractors, evaluating bids and recommending a subcontractor, coordinating and overseeing abatement, and performing inspections and clearance. Abatement included the removal of deteriorating LBP from exterior porches, columns, and window frames; and the removal of deteriorating asbestos insulation from heat and air ducts.

QE2 developed, maintained, or updated more than 120 SPCC Plans for State-owned facilities for 14 different State agencies, as regulated by Title 40 Part 112 of the Code of Federal Regulations (CFR).  QE2 systematically reviewed all information available for all State-owned buildings to determine which facilities needed SPCC Plans. QE2 conducted thorough site inspections at each facility to identify all oil storage containers including tanks, drums, transformers, and hydraulic elevators, all of which are covered under the SPCC rule.  QE2 created a standardized SPCC Plan format which would accommodate all State SPCC Plans and meet all regulatory requirements. QE2 prepared the SPCC Plans, which were stamped by a Professional Engineer, and provided training to facility personnel.  QE2 revised the plans due to changes in tanks, their locations, or staffing, and maintained the Program by reviewing and re-certifying all of the SPCC Plans upon their 5 year renewal dates, or at the point a facility notified us of a change to the oil bearing equipment onsite.
The SSTP was part of TDF&A’s environmental responsibility since the late 1980s, and has accomplished the assessment, remediation and closure of hundreds of leaking USTs. When the 2003 SES Contract was initiated, TDF&A rolled 88 UST sites still undergoing remediation or closure activities into the SES Contract. By the time the 2008 Contract began, QE2 had closed 69 of those 88 sites. During the 2008 Contract term, several more sites were closed and some were transferred to a Tennessee Department of Transportation (TDOT) consultant. Only one site remained active at the close of QE2’s run as Statewide Environmental Services Contractor. This program involved work performed by team members and utilizes subcontractors in the drilling and analytical laboratory lines extensively.
