Lift Slab
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the need to form floor work in place. The ability to create monolithic concrete slabs makes the lift slab construction technique useful in quickly creating structures with repetitive form work, like parking ramps. History This method of construction simultaneously began development in 1948 by both Philip N. Youtz of New York and Thomas B Slick of Texas. Although the first patent for lift slab construction was given to Slick in 1955, the method of construction is commonly referred to as the "Youtz-Slick Method". His patent called for a method that would allow for fabrication to be completed at the ground level, eliminate a large portion of the form ...

Woodrow Wilson High School (Portland, Oregon)
Ida B. Wells-Barnett High School, formerly known as Woodrow Wilson High School (and colloquially as Wells High School), is a public high school in Portland, Oregon, United States. History Wells High School (originally Woodrow Wilson High School) was built in 1956, after a ballot measure was passed in 1945 providing $5 million to improve Portland's school system. Population was growing explosively, so emphasis was put on economy and ease of building, instead of on architectural style as was the norm in the earlier school buildings. Wells High School, which was designed by the firm Edmundson and Kochendoerfer, used the technique of lift-slab construction to speed up construction. Wells was the first building in the Northwest to use that technique. In July 2020, Portland Public Schools pledged to rename the school in response to pressure from the community in light of the racial justice movement that followed the murder of George Floyd. In January 2021, the name was changed to Ida ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ...

Tilt Slab
Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete. Though it is a cost-effective technique with a shorter completion time, poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings. With the tilt-up method, concrete elements (walls, columns, structural supports, etc.) are formed horizontally on a concrete slab; this normally requires the building floor as a building form but may be a temporary concrete casting surface near the building footprint. After the concrete has cured, the elements are "tilted" to the vertical position with a crane and braced into position until the remaining building structural components (roofs, intermediate floors and walls) are secured. Tilt-up construction is a common method of construction throughout North America, several Caribbean nations, Australia, and New Zealand. It is not significantly used in Europe or the northern two thirds of Asia. It is gaining ...

Load-bearing Wall
A load-bearing wall or bearing wall is a wall that is an active structural element of a building, which holds the weight of the elements above it, by conducting its weight to a foundation structure below it. Load-bearing walls are one of the earliest forms of construction. The development of the flying buttress in Gothic architecture allowed structures to maintain an open interior space, transferring more weight to the buttresses instead of to central bearing walls. In housing, load-bearing walls are most common in the light construction method known as "platform framing". In the birth of the skyscraper era, the concurrent rise of steel as a more suitable framing system first designed by William Le Baron Jenney, and the limitations of load-bearing construction in large buildings, led to a decline in the use of load-bearing walls in large-scale commercial structures. Description A load-bearing wall or bearing wall is a wall that is an active structural element of a building, ...

Jack (device)
A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load. Etymology The personal name ''Jack'', which came into English usage around the thirteenth century as a nickname form of ''John'', came in the sixteenth century to be used as a colloquial word for 'a man (of low status)' (much as in the modern usage 'jack of all trades, master of none'). From here, the word was 'applied to things which in some way take the place of a lad or man, or save human labour'. The first attestation in the ''Oxford English Dictionary'' of ''jack'' in the sense 'a machine, usually portable, for lifting ...

Cambridge News
The ''Cambridge News'' (formerly the ''Cambridge Evening News'') is a British daily newspaper. Published each weekday and on Saturdays, it is distributed from its Waterbeach base. In the period December 2010 – June 2011 it had an average daily circulation of 20,987, but by December 2016 this had fallen to around 13,000. In 2018, the circulation of the newspaper fell to 8,005 and by June 2022 the preceding 6-month average was 3,552 readers per issue. History The paper was founded by William Farrow Taylor as the ''Cambridge Daily News'' in 1888, and after a slow start saw sales rise as an appetite for knowledge of the news and sport grew among the Cambridge public. As its following steadily grew, the fledgling paper survived the need for modernisation in the early twentieth century (Captain Archibald Taylor, son of the founder, was the first managing director to introduce a standard typeface during this time, for example), the uncertain economic climate during the 1920s and 19 ...

Moratorium (law)
A moratorium is a delay or suspension of an activity or a law. In a legal context, it may refer to the temporary suspension of a law to allow a legal challenge to be carried out. For example, animal rights activists and conservation authorities may request fishing or hunting moratoria to protect endangered or threatened animal species. These delays, or suspensions, prevent people from hunting or fishing the animals in discussion. Another instance is a delay of legal obligations or payment (''debt moratorium''). A legal official can order due to extenuating circumstances, which render one party incapable of paying another. See also *Justice delayed is justice denied *Moratorium (other) Moratorium (from Late Latin ''morātōrium'', neuter of ''morātōrius'', "delaying"), may refer to: Law *Moratorium (law), a delay or suspension of an activity or a law Music *"Moratorium", a song by Alanis Morissette on her album ''Flavors of E ...
