An 1865 map of Lower Manhattan below 14th Street showing land reclamation along the shoreline. [1] The expansion of the land area of Lower Manhattan in New York City by land reclamation has, over time, greatly altered Manhattan Island's shorelines on the Hudson and East rivers as well as those of the Upper New York Bay. The extension of the ...
A trial pit (or test pit) is an excavation of ground in order to study or sample the composition and structure of the subsurface, usually dug during a site investigation, a soil survey or a geological survey. [1] Trial pits are dug before the construction. They are dug to determine the geology and the water table of that site.
Essex Crossing is an under-construction mixed-use development in New York City's Lower East Side, at the intersection of Delancey Street and Essex Street just north of Seward Park.

The information in a soil survey can be used by farmers and ranchers to help determine whether a particular soil type is suited for crops or livestock and what type of soil management might be required. An architect or engineer might use the engineering properties of a soil to determine whether it is suitable for a certain type of construction.

The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...
The consolidation cell is the part of the oedometer that holds the soil sample during a test. At the centre of the consolidation cell is a sample ring where the soil sample is held. The sample ring is typically shaped like a cookie cutter , with a sharp edge on one side, so the ring can be used to cut out a sample slice of soil from a larger ...
