- Installed Lennox VRF system with two ceiling cassettes in the cryogenic freezer room.
HVAC Backup for Server Room
The National Oceanic and Atmospheric Administration (NOAA) Southwest Fisheries Science Center (SWFSC) was constructed in 2014.
The facility contains 38 research laboratories, a library, conference rooms, and office space for 275 scientists and support staff. SWFSC provides scientific research to support the management and conservation of domestic and international living marine resources.
In 2017, NOAA funded the upgrade of existing computer room air conditioners (CRACs) in three locations. This upgrade was necessary to preserve critical functions during a potential catastrophic equipment failure or during periodic major preventative maintenance, so that in the event of a loss of chilled water the Dual Cooled Liebert would take over and provide uninterrupted mechanical cooling.
Lennox VRF (Variable Refrigerant Flow) mechanical cooling was also added to the cryogenic freezer room and a second server room to prevent overheating during a loss of chilled water.
Ahtna Global completed the following actions within an occupied building, while maintaining an optimal temperature and preventing downtime of the mission-critical facility.
Management & Data Analyst Services
As a preferred contractor for the AKARNG, Ahtna Global was contracted to provide non-personal services for the Network Enterprise Center (NEC), AKARNG, Joint Base Elmendorf-Richardson (JBER), AK, through August of 2020.
This contract encompasses clerical, technical, and analytical services in the execution of NEC’s broad and diverse mission to facilitate operational requirements in accordance with Army regulations for purchasing. These services monitor projects, prepare documentation, and reconcile all actions to fulfill regulatory requirements for all contract purchase acquisitions through the United States Purchasing and Financial Office of Purchasing and Contracting (USPFOP-C).
The output generated takes on many forms, such as maintaining and/or creating spreadsheets/tables that provide accurate tracking of voucher distribution; budget execution; project timeline reporting; data collection for manpower studies; product review reporting, initial document preparation, memorandums, reports, presentations, and record retention maintenance.
By providing these services, the NEC management team remains unencumbered, allowing for technical implementation and long-term planning for the AKARNG. These efficiencies allow NEC to maintain audit readiness and compliance with complex regulatory requirements in the area of contract acquisitions and record management.
Glacier Bay National Park
In an effort to accommodate more people, the NPS contracted Ahtna Global to perform park trail rehabilitations allowing visitors in wheelchairs to access the lodge’s front door.
Ahtna performed all work during the lodge’s off-season, ensuring minimal impact to operations.
The project consisted of the following activities:
- Demolition of existing concrete sidewalks/slabs and asphalt.
- Clearing and grubbing of sod.
- Excavation of unsuitable material and placement of classified fill to a specified grade verified by survey control.
- Constructing ADAAG/ABA compliant concrete sidewalks and ramps with integrated prefabricated trench drains.
- And installation of wood railings and wood pedestrian benches, including fabrication of all new stainless steel hardware.
In addition to the activities listed above, Ahtna also moved and extended an existing historic stairway and boardwalk to accommodate head height for visitors using the new ramp.
The Glacier Bay Lodge is of historical importance given the history of the building. As a result, Ahtna will be milling lumber to special dimensions to match the existing wood and historical appearance of the lodge.
Invasive Species Survey
Ahtna Global was subcontracted to perform the necessary survey and provide a comprehensive report of findings. Ahtna completed the work during the 2017 growing season, documenting invasive species as they were found. At the conclusion of the project, Ahtna provided a written report and area/point match.
Field work was conducted by a two-person team, mobilized out of Ahtna’s Anchorage and Fairbanks offices. A total of 57 survey plots were delineated and surveyed, encompassing approximately 76 acres.
Field survey methods employed a combination of transects, comprehensive areal assessments, and ocular estimation to determine non-native plant abundance and distribution.
All non-native plant species were documented and a written report of findings was provided. The report included an area/point map, collected volumes of each species, locations of controlled and monitored areas, comparative discussion of previous years’ findings, and future recommendations.
Woody Island Station
The Woody Island Radio Range Station (RRS) is a former Civil Aeronautics Administration navigation facility that was constructed during World War II (1941).
Manned Federal Aviation Administration (FAA) operations at Woody Island ended in 1973, when FAA-owned land and most buildings were transferred to the Woody Island Tribal Council. The FAA currently maintains five unmanned facilities on Woody Island including a VOR Station and/or Tactical Air Navigation, non-directional beacon, Remote Communications Air/Ground (RCAG), Direction Finder (DF), and a Shop building.
Through previous investigative efforts, the FAA determined a need for the removal of debris and contaminated soil located in three separate areas of concern.
As a preferred contractor for the FAA, Ahtna Global was contracted to perform the following activities to accomplish FAA’s cleanup mission.
Removal and disposal of debris (batteries, electrical components, concrete, scrap steel, cables, furniture, and drums with non-hazardous content) located at the former dump site near the Communications Tower.
Excavation, stockpiling, characterization, and disposal of 600 cubic yards of contaminated soil from the former dump site. Dump materials included RCRA lead soils, TSCA PCB soils, asbestos contaminated soils, and non-hazardous soils.
Removal and disposal of the DF and associated infrastructure near the active RCAG.
Collection of soil samples from the former north drum area at the VOR site to determine onsite contaminants.
