The cantonal civil engineering department tenders cantonal roads inside and outside built-up areas, often combined with cycle paths, utility lines and flood protection. The Federal Roads Office's Zofingen branch awards design and site supervision for motorway maintenance projects, and Swissgrid, based in Aarau, engineering and acceptance work for overhead lines and substations. Municipalities look for general planners for school buildings and sports facilities, and the canton's department for construction, transport and environment awards consulting mandates in the energy field.
