Existing Topography

Existing Topography – with footprint

Estimated Topography

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
