Battelle announced the award in this 25 June press release. But this has been a long slog.
First, a bit of history. Polar Field Services (PFS) (the incumbent and other bidder) first started supporting NSF's Arctic program in December 1999 per this 2009 PFS blog post. The leader in the establishment of PFS was Jill Ferris, who worked in McMurdo beginning in 1984 as a shuttle driver...she would winter as the BFC manager and eventually became the Field Operations Manager for ASA in the 1990's. In 1999 she formed the company Polar Field Services, which submitted the successful proposal that year to win NSF's Arctic support contract. Two references to this...first, this 2019 OSU Byrd Polar and Climate Research Center article about her, as she spoke at the Women in Antarctica symposium which I attended in October 2019...and also this March 2019 Arctic Institute article by friend Morgan Seag who briefly mentions Jill's leadership in establishing PFS.
Originally, Polar Field Services was an entity of the Anchorage oilfield service and construction company VECO...as I was working in Alaska (for Fluor, farmed out to Alyeska for construction projects mostly in Valdez) in 1990-92 I saw and heard about a bunch of VECO history...I'll spare you most of the sordid details about the VECO corruption scandal here (which involved Sarah Palin and Senator Ted Stevens) except to mention that VECO acquired the former Anchorage Times newspaper, which I saw the demise of while I was there. Have a look at the VECO Wikipedia page for details.
In September 2007, CH2M Hill acquired most of the remaining assets of VECO, including PFS. PFS would continue to win the NSF Arctic support contracts. In 2015 they removed the word "Hill" from their branding. And in December 2017, Jacobs Engineering Group acquired CH2M.
On 1 February 2012, PFS started their most recent Arctic support contract...four years with two potential 2-year extensions. NSF first announced a presolicitation for rebidding this contract in September of 2017. At the time I was unsure of the schedule...the actual solicitation was first issued in February 2019, and the eventual bid due date after an extension was 7 June 2019. The award to Battelle was officially announced on 20 December 2019, but CH2M (Jacobs Polar Services-CH2M Facility Support Services of Englewood, Colorado) immediately protested. According to this GAO report from 12 June, the PFS appeal was denied. I don't understand all of the legalese in this report, although I've read the detailed explanation. One thing I did not know was that Jacobs considered PFS as a subcontractor per this page, and accordingly Battelle did so as well. The detailed news and analysis is behind expensive paywalls.
