    Švedska elektro mreža širi nacionalnu mrežu oko Långsele iz razloga zagušenosti ovih stanica tokom zime. Rad će se odvijati na tri lokacije. Dve u Hjälta-u i jedna u Helgum-u. Stanica u Helgum-u podrazumeva izgradnju nove , dok je na druge dve u Hjälta-u planirano proširenje kapaciteta.

    „Vattenfall Services Nordic“ je određen za implementaciju projekta od Švedske elektro mreže. Uloga ASTM u projektu je pomoć „Vattenfall Services Nordic“ u vidu  tehničke podrške na izgradnji, u fazi planiranja i izvođenja radova. Tehnička podrška se sastoji od planiranja,praćenja  izgradnje vezano za kvalitet, dinamički plan  i finansije. Faza planiranja je u toku sa ciljem otpočinjanja radova na izgradnji u Aprilu 2017. i planiranim završetkom krajem 2018.


  • Substation - Kolbotten

    Švedska elektro mreža je angažovala ”INFRATEK” za nadogradnju trafostanice u Kolbotten-u, Švedska. Novi električni sistem će biti montiran na čeličnom okviru koji će biti usidren na već postojećem betonskom temelju. ASTM AB zadatak je da ispita stvarno stanje kvaliteta postojećeg betona u temelju i podnese pisani izvještaj o rezultatima ispitivanja betona temelja i da dostavi predlog mera. ASTM će kasnije biti odgovoran za planiranje i izgradnju odabranih mera.
