Updated Floor Plan

Updated Floor Plan

• 6’ Porch• Larger office space• Shower – exterior• Pathway to shower/latrine• Larger storage• Labor to Delivery to Recovery• Waiting room sectioned off from patient

areas

Other Updates

• Use of columns for roof loads

• Use of mud bricks for interior walls

• Roof pitch = 15° for solar panels– Peak of roof = 8’-8”

• Windows in all rooms except delivery/labor

• Ok to use translucent roof material

Next Steps

• Edit Topo Plots, find optimal cut and fill foundation depth

• Determine specifications and dimensions of spread and strip footings

• Determine amount of materials

• Design roof structure

• Create construction timeline
