      <Desc>The Carleton Laboratory relied on the allocation from these funds, not only for staffing and research support, but also for ongoing improvement and modernization of the Laboratory facilities in conjunction with income from a number of applied testing projects. In parallel to efforts of the School of Engineering, the Laboratory has placed particular focus on improving its aging core infrastructure, where significant progress has been made. Projects included the continued upgrade of the loading dock, the upgrade and replacement of electrical feeders throughout the Laboratory, upgrade of various laboratory utilities, and other components of the built environment. Investments have also been made to improve the teaching experience of numerous undergraduate and graduate courses with the purchase of a new civil engineering scale laser cutter.</Desc>
