After their carport burned, Larry and Victoria Santiago desired an 800 sq ft attached

        garage to their home in west Anchorage.  To comply with the Anchorage Municipality

        code, the Santiago's were required to install a 42" height block or concrete foundation

        and footing. To save cost Nushagak Consultants in association with the Santiago's

        submitted a frost protected thicken edge design as an alternate to the Municipalities

        requirement.  It was approved!

          This design only works with a heated structure. It relies on the use of two sheets of

        rigid, polystyrene insulation-one on the outside of the foundation wall and the other

        laid flat on a bed of gravel at the base of the wall-to prevent freezing, which is a problem

        with slab-on grade foundations in areas with frost. The insulation holds heat from the

        structure in the ground under the footings and prevents heat loss from the edge of the

        slab. This heat keeps the ground temperature around the footings above freezing.

          The scope of work was completed by Nushagak Consultants as shown in the pictures

        below. A footnote to this project was a compliment from Alaska Sand & Gravel when they

        delivered the fiber reinforced concrete for the pour. They were very impressed by the

        meticulous way the concrete forms were constructed and the perfect 45 degree angles of

        the aggregate slopes. They delightfully admitted; "They would recommend Nushagak

        Consultants to anyone". Nushagak also completed conceptual building design drawings

        for the Santiago's. The Front view can be seen by clicking on the wheelbarrow below.
