Lumber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

Naval Air Station Alameda
Naval Air Station Alameda (NAS Alameda) was a United States Navy Naval Air Station in Alameda, California, on San Francisco Bay. NAS Alameda had two runways: 13–31 measuring and 07-25 measuring . Two helicopter pads and a control tower were also part of the facilities. History In 1927, wetlands at the west end of Alameda Island on the east shore of San Francisco Bay were filled to form an airport (Alameda Airport) with an east–west runway, three hangars, an administration building, and a yacht harbor. The airport site included the Alameda Terminal of the First transcontinental railroad (California Historical Landmark #440). By 1930, United States Army Air Corps operations referred to the site as Benton Field. Pan American World Airways used the yacht harbor as the California terminal for ''China Clipper'' trans-Pacific flights beginning in 1935. The ''China Clipper'' terminal is designated California Historical Landmark #968. On 1 June 1936, the city of Alameda, Californ ...

Port Of Oakland
The Port of Oakland is a major container ship facility located in Oakland, California, in the San Francisco Bay. It was the first major port on the Pacific Coast of the United States to build terminals for container ships. As of 2011 it was the fifth busiest container port in the United States, behind Long Beach, Los Angeles, Newark, and Savannah. Development of an intermodal container handling system in 2002 after over a decade of planning and construction positions the Port of Oakland for further expansion of the West Coast freight market share. In 2019 it ranked 8th in the United States in the category of containers. Early history In 1852, the year of Oakland's incorporation as a town by the California State Legislature, large shipping wharves were constructed along the Oakland Estuary, which was dredged to create a viable shipping channel. 22 years later, in 1874, the previously dredged shipping channel was deepened to make Oakland a deep water port. In the late 19th cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bay Farm Island Bridge
The San Leandro Bay Bridge, better known as the Bay Farm Island Bridge, is a single-leaf bascule drawbridge spanning the San Leandro Channel, the inlet of San Leandro Bay within the San Francisco Bay Area, California, United States. It carries California State Route 61 and links the main island of Alameda with Bay Farm Island within the city of Alameda.

The Bay Farm Island Bridge is one of the four bridges and two tunnels linking Alameda Island with the mainland. It is the longest bridge of the four. History A toll bridge at this location was first built in 1854, consisting of a wooden trestle surfaced with crushed oyster shells. The owners abandoned the bridge after a failed business deal for land on Bay Farm Island, and the 1854 bridge subsequently rotted. Alameda County constructed a second bridge ...

Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.
