Construction Site at the Central Zoo

During our visit to the Zoo, there were a number of workers laboring on a construction project near the main gate. From what I have seen, demolition and construction are powered with human labor using basic tools--the 30 foot well at a nearby restaurant was dug by one man with a shovel supported by two men and a young boy on the surface; the bricks and mortar for the third floor of the house across the street were carried from piles on the street by women with baskets and tumplines; the 12 foot stone wall was dismantled with a hammer. The one exception has been the few pieces of heavy equipment I've seen in use for building and re-surfacing roads.
