Maintenance Shed This structure is constructed of wood roof and wall framing on an integral concrete foundation and floor. It was rehabilitated in 2015 with structural input from JVA. Since the building was not accessible for the assessment, all interior observations are based on our previous design and construction administration experience with the building. Foundation and Floor The shed is constructed on a 5" thick reinforced concrete slab-on-grade with a turned down slab edge that extends a minimum of 18” below grade. The foundation is in good condition showing no signs of subsidence or other displacement. Roof Framing The gable roof is framed with 2x4 rafters spaced at approximately 24” on center at an 8 on 12 slope. Original and new collar ties installed in 2014 span across each rafter pair at the top of wall elevation. The roof is sheathed with a layer of 1x variable width skip sheathing and a layer of plywood sheathing. The roof framing is in good structural condition since the overall system is performing well and there are no indications of failures or displacement from the exterior. Wall Framing The walls are framed with flat 2x4 studs aligned with the bearing of each rafter pair. A 2x4 plate tops the walls and 2x4 girts at the third points of the wall height span around the perimeter of the building. At the base, the flat studs bear on 2x6 upright plates around the perimeter of the building that are braced by inset flat 2x6 plates anchored into the foundations. Holdowns from the wall framing into the foundation are located at each corner and on either side of the south door. A double 2x10 header spans over the door opening. The studs are sheathed with 1x variable width vertical siding.
The wall framing is in good structural condition from the exterior showing no signs of failure or displacement. There are some minor issues located in isolated locations.
There are a few locations where there is some impact damage to the wood siding that have created holes in the envelope. Other areas of the trim and siding are deteriorating due to decay fungi infestation, typically close to grade or where vegetation is close to the building. The trim at the west jamb of the south door is broken at the
