STD-4C
STD-4C or STANDARD-4C refers to a set of standards and regulations set by the United States Postal Service regarding the specifications of cluster mailbox units used in new construction. All multi unit constructions building plans submitted after October 6, 2006 are required to use STD-4C compliant mailboxeshttp://about.usps.com/postal-bulletin/2010/pb22284/pdf/pb22284.pdf STD-4C mailboxes The STD-4C is the current USPS regulation for any centralized, wall-mounted mailboxes, whether located inside an office high-rise or within a new single-family subdivision as an outdoor centralized mailbox kiosk. New STD-4C compliant mailboxes are commonly referred to as centralized mail delivery equipment. The Postal Service modified the regulation for new construction due to changing customer mailing habits and specific mail and package volume trends. Postal Service statistics indicate customers receive more mail and of varying sizes than at the time of the last updated standard which pres ...

Centralized Mail Delivery
Centralized mail delivery is a unique form of mail delivery system where a letter carrier provides delivery and collection services to a number of residences from a centrally located installation – whether in a single-family subdivision or multi-family structure. Business customers also receive delivery services from a convenient central location. Centralized mail delivery equipment can be in the form of any "clustered" type mailbox – including free-standing, pedestal-mounted cluster box unit (CBU), or other cluster mailboxes mounted in a wall, kiosk, or shelter. The U.S. Postal Service prefers centralized mail delivery in all new construction because it is less expensive. The United States Postal Service aims to continue to review and modify its operations to provide universal service as efficiently and cost effectively as possible. Therefore, there is pressure to establish centralized mail delivery, which is required in some communities. History Mail delivery can be traced b ...

Arrow Lock
An arrow lock is a lock with standard dimensions used by the United States Postal Service for mail carriers to access collection boxes, outdoor parcel lockers, cluster box units, and apartment mailbox panels. Arrow locks are unlocked through the use of a corresponding ''arrow key''. Arrow locks are also referred to as "Master Access Locks" Dimensions and mounting An arrow lock is metal and rectangular, measuring 2.005” x 3.566” x .620”, with a keyhole in the center. When the user turns the key, a metal bar that normally protrudes from one side is moved through the lock to the other side. This action may be used to release a door (as in the case of a collection or parcel box) or to press/release a switch (as in the case of an electronic door release). Arrow locks have four mounting holes, which are evenly spaced at the corners, providing for secure attachment to four 10-32 threaded studs with metal nuts. A ⅞” hole in the mounting surface is necessary to accommod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letter Box
A letter box, letterbox, letter plate, letter hole, mail slot or mailbox is a receptacle for receiving incoming mail at a private residence or business. For outgoing mail, Post boxes are often used for depositing the mail for collection, although some letter boxes are also capable of holding outgoing mail for a carrier to pick up. Letterboxes or mailboxes use the following primary designs: * A slot in a wall or door through which mail is delivered (through-door delivery) * A box attached directly to the building (direct-to-door delivery) * A box mounted at or near the street ( curbside delivery) * A centralised mail delivery station consisting of individual mailboxes for an entire building also known as a "flock" throughout the South Island of New Zealand and parts of America. * A centralised mail delivery station consisting of individual mailboxes for multiple recipients at multiple addresses in a particular neighborhood or community Styles and usage A "letter box", or "mail ...

Technical Standard
A technical standard is an established norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices. A technical standard includes definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength. It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes, and practices. In contrast, a custom, convention, company product, corporate standard, and so forth that becomes generally accepted and dominant is often called a ''de facto'' standard. A techni ...

Regulation
Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context. For example: * in biology, gene regulation and metabolic regulation allow living organisms to adapt to their environment and maintain homeostasis; * in government, typically regulation means stipulations of the delegated legislation which is drafted by subject-matter experts to enforce primary legislation; * in business, industry self-regulation occurs through self-regulatory organizations and trade associations which allow industries to set and enforce rules with less government involvement; and, * in psychology, self-regulation theory is the study of how individuals regulate their thoughts and behaviors to reach goals. Social Regulation in the social, political, psychological, and economic domains can take many forms: legal restriction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Postal Service
The United States Postal Service (USPS), also known as the Post Office, U.S. Mail, or Postal Service, is an independent agency of the executive branch of the United States federal government responsible for providing postal service in the U.S., including its insular areas and associated states. It is one of the few government agencies explicitly authorized by the U.S. Constitution. The USPS, as of 2021, has 516,636 career employees and 136,531 non-career employees. The USPS traces its roots to 1775 during the Second Continental Congress, when Benjamin Franklin was appointed the first postmaster general; he also served a similar position for the colonies of the Kingdom of Great Britain. The Post Office Department was created in 1792 with the passage of the Postal Service Act. It was elevated to a cabinet-level department in 1872, and was transformed by the Postal Reorganization Act of 1970 into the U.S. Postal Service as an independent agency. Since the early 1980s, m ...

New-construction Building Commissioning
Building commissioning (Cx) is an integrated, systematic process to ensure, through documented verification, that all building systems perform interactively according to the "Design Intent". The commissioning process establishes and documents the "Owner's Project Requirements (OPR)" criteria for system function, performance expectations, maintainability; verify and document compliance with these criteria throughout all phases of the project (design, manufacturing, installation, construction, startup, testing, and operations). Commissioning procedures require a collaborative team effort and 'should' begin during the pre-design or planning phase of the project, continue through the design and construction phases, initial occupancy phase, training of operations and maintenance (O&M) staff, and into occupancy (for warranty and future re-commissioning). Historically, “commissioning” as referenced in building design and construction, referred to the process by which the heating, ve ...

High-rise Building
A tower block, high-rise, apartment tower, residential tower, apartment block, block of flats, or office tower is a tall building, as opposed to a low-rise building and is defined differently in terms of height depending on the jurisdiction. It is used as a residential, office building, or other functions including hotel, retail, or with multiple purposes combined. Residential high-rise buildings are also known in some varieties of English, such as British English, as tower blocks and may be referred to as MDUs, standing for multi-dwelling units. A very tall high-rise building is referred to as a skyscraper. High-rise buildings became possible to construct with the invention of the elevator (lift) and with less expensive, more abundant building materials. The materials used for the structural system of high-rise buildings are reinforced concrete and steel. Most North American-style skyscrapers have a steel frame, while residential blocks are usually constructed of concrete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobby (room)
A lobby is a room in a building used for entry from the outside. Sometimes referred to as a foyer, reception area or an entrance hall, it is often a large room or complex of rooms (in a theatre, opera house, concert hall, showroom, cinema, etc.) adjacent to the auditorium. It may be a repose area for spectators, especially used before performance and during intermissions, but also as a place of celebrations or festivities after performance. Since the mid-1980s, there has been a growing trend to think of lobbies as more than just ways to get from the door to the elevator but instead as social spaces and places of commerce. Some research has even been done to develop scales to measure lobby atmosphere to improve hotel lobby design. Many office buildings, hotels and skyscrapers go to great lengths to decorate their lobbies to create the right impression and convey an image.

Consensus Decision-making
Consensus decision-making or consensus process (often abbreviated to ''consensus'') are group decision-making processes in which participants develop and decide on proposals with the aim, or requirement, of acceptance by all. The focus on establishing agreement of at least the majority or the supermajority and avoiding unproductive opinion differentiates consensus from unanimity, which requires all participants to support a decision. Origin and meaning of terms The word ''consensus'' is Latin meaning "agreement, accord", derived from ''consentire'' meaning "feel together". Broadly, ''consensus'' relates to a generally accepted opinion, but in the context of this article refers to the process ''and'' the outcome of consensus decision-making (e.g. "to decide ''by'' consensus" and "''a'' consensus was reached"). History Consensus decision-making, as a self-described practice, originates from several nonviolent, direct action groups that were active in the Civil rights, Peace ...

Manufacturing
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final p ...

Distributor
A distributor is an enclosed rotating switch used in spark-ignition internal combustion engines that have mechanically timed ignition. The distributor's main function is to route high voltage current from the ignition coil to the spark plugs in the correct firing order, and for the correct amount of time. Except in magneto systems and many modern computer controlled engines that use crank angle/position sensors, the distributor also houses a mechanical or inductive breaker switch to open and close the ignition coil's primary circuit. The first reliable battery operated ignition was the Delco ignition system developed by Dayton Engineering Laboratories Co. (Delco) and introduced in the 1910 Cadillac Model 30. This ignition was developed by Charles Kettering and was considered a wonder in its day. Atwater Kent invented his Unisparker ignition system about this time in competition with the Delco system. By the end of the 20th century mechanical ignitions were disappearing from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
