A pile splice joins two segments of a driven pile, using either a weld (typical for H beams), grout or mechanical means (typical for precast concrete piles). Pile splices enable the use of shorter segments, which allows for driving piles in low-headroom situations such as under bridges or inside buildings. [1] Reducing length of pile segments to under ~65 feet long also means the trailers that haul them to job sites can stay within state length limits. [2]
Geotechnics is the application of scientific methods and engineering principles to the acquisition, interpretation, and use of knowledge of materials of the Earth's crust and earth materials for the solution of engineering problems and the design of engineering works. It is the applied science of predicting the behavior of the Earth, its various materials and processes towards making the Earth more suitable for human activities and development.

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed, so as to improve the behaviour of the final structure under working loads. In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning.
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to. They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead.
In construction or renovation, underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be necessary for a variety of reasons:
Bangabandhu Bridge, commonly called the Jamuna Multi-purpose Bridge is a bridge opened in Bangladesh in June 1998. It connects Bhuapur on the Jamuna River's east bank to Sirajganj on its west bank. It was the 11th longest bridge in the world when constructed in 1998 and currently is the 6th longest bridge in South Asia. The Jamuna River, which it spans, is one of the three major rivers of Bangladesh, and is fifth largest in the world in discharge volume.
The Bandra–Worli Sea Link is a cable-stayed bridge with pre-stressed concrete-steel viaducts on either side that links Bandra in the Western Suburbs of Mumbai with Worli in South Mumbai. The bridge is a part of the proposed Western Freeway that will link the Western Suburbs to Nariman Point in Mumbai's main business district.
A pile driver is a device used to drive piles into soil to provide foundation support for buildings or other structures. The term is also used in reference to members of the construction crew that work with pile-driving rigs.
A dolphin is a man-made marine structure that extends above the water level and is not connected to shore.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.
A pile is a slender element cast in the ground or driven into it. Since pile construction as well as the final product are mostly invisible, engineers have often questioned their integrity, i.e. their compliance with project drawings and specifications. In fact, experience has shown that in piles, of all kinds flaws may occur. The purpose of integrity testing is to discover such flaws before they can cause any damage.
A tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems to provide additional stability to cantilevered retaining walls. With one end of the tieback secured to the wall, the other end is anchored to a stable structure, such as a concrete deadman which has been driven into the ground or anchored into earth with sufficient resistance. The tieback-deadman structure resists forces that would otherwise cause the wall to lean, as for example, when a seawall is pushed seaward by water trapped on the landward side after a heavy rain.
Continuous flight augering (CFA), also known as auger cast piling, is a technique used in construction to create a concrete deep foundation.
The Brandywine Shoal Light is a lighthouse on the north side of the ship channel in Delaware Bay on the east coast of the United States, west of Cape May, Cape May County, New Jersey, United States. It was the site of the first screw-pile lighthouse in the United States.
The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test. The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands. Guidance on rapid load pile testing can be found in: Methods for Axial Compressive Force Pulse (Rapid) Testing of Deep Foundations. Sanken D7383 - 08 Standard Test.
The Inner Harbor Navigation Canal Lake Borgne Surge Barrier is a storm surge barrier constructed near the confluence of and across the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO) near New Orleans. The barrier runs generally north-south from a point just east of Michoud Canal on the north bank of the GIWW and just south of the existing Bayou Bienvenue flood control structure.
Western Channel Pile Light, also known as the West Wedding Cake due to its shape, is an active pile lighthouse located at the Sydney Harbour, New South Wales, Australia, off Georges Head at Mosman. It marks the western end of the Sow and Pigs Reef. It collapsed in December 2006 and was reconstructed and restored to operation in December 2008.
The Franki piling system is a method used to drive expanded base cast-in-situ concrete (Franki) piles. It was developed by Belgian Engineer Edgard Frankignoul in 1909 and has achieved considerable worldwide success since.
The Konkrete Etüde is the earliest work of electroacoustic tape music by Karlheinz Stockhausen, composed in 1952 and lasting just three-and-a-quarter minutes. The composer retrospectively gave it the number "⅕" in his catalogue of works.
The Samuel De Champlain Bridge is a twin cable-stayed bridge built to replace the original Champlain Bridge over the Saint Lawrence River in Quebec between the Island of Montreal and the South Shore suburbs. The new twin spans are located just north of the original Champlain Bridge, which both run east-west over the north-south river. The new bridge's north span carries the northbound and westbound automobile traffic of the A-10, A-15, and A-20. The south span carries the southbound and eastbound automobile traffic of the A-10, A-15 and A-20. The central span, still under construction, will carry the South Shore branch of the forthcoming Réseau express métropolitain automated light rail system. It is one of the largest infrastructure projects in North America and is one of the busiest crossings on the continent. It is built to last 125 years with the usage of stainless steel and high-performance concrete, and replaces the previous 57-year-old bridge, which has become functionally obsolete and its structure having been degraded by the repeated application of de-icing salt. At approximately 60 metres (200 ft) wide, the new Champlain Bridge is one of the widest bridges in the world.
