STAIRS Staircase is an important component of a building providing us the access to different floors and roof of the building. It consists of a flight of steps (stairs) and one or more intermediate landing slabs between the floor levels. Different types of staircases can be made by arranging stairs and landing slabs. Stairs can be made of concrete, stone, wood, steel or combination of any of these. Primary functions of staircase • Provide an access from one floor to another. • Provide a safe means of travel between floors. • Provide an easy mean of travel between floors. • Provide a suitable means of escape in case of fire. • Provide a mean of conveying fittings and furniture between floor levels. General terminologies used in Staircase 1. Steps - A series of horizontal open treads with a space between the treads with a space between the treads or as enclosed steps with a vertical face between the treads as shown in the figure below. • Tread – horizontal surface of a step • Riser – vertical surface or near vertical of a step 2. Nosing - In some cases the tread is projected outward to increase the space. -

Types of Stairs
Types of Stairs Straight stairs are certainly one of the most common types of stairs found in both residential and commercial properties. Examples of Straight Stairs: L Shaped Stair (or sometimes called quarter turn stairs) The L shaped stair is a variation of the straight stair with a bend in some portion of the stair. This bend is usually achieved by adding a landing at the bend transition point. The bend is often 90 degrees, however it does not have to be. If the landing is closer to the top or bottom of the stairs it is sometimes referred to as a long L stair. Example of L Shaped Stairs: U shaped Stairs (or sometimes called half turn stairs or switchback stairs) U Shaped stairs are basically 2 parallel flights of straight stairs joined by a landing that requires 180 degree turn in the walk line. If a third flight is inserted into the middle of the stairs, it would become a double L stair (or quarter landing). Example of U Shaped Stairs: Quarter Landing Stairs Examples of Quarter Landing Stairs: Winder Stairs Winder stairs are a variation of an L shaped stair but instead of a flat landing, they have pie shaped or triangular steps at the corner transition. Examples of Winder Stairs: Spiral Stairs Spiral stairs are a often confused with curved stairs. Although, both types of stairs follow a helical arc (like the shape of a spring), spiral stairs usually are made very compact and the treads radiate around a center pole. Example of Spiral Stairs: Curved Stairs Curved stairs add elegance to home or business. -
Interim Guidance for Office-Based Work During the Covid-19 Public Health Emergency
INTERIM GUIDANCE FOR OFFICE-BASED WORK DURING THE COVID-19 PUBLIC HEALTH EMERGENCY When you have read this document, you can affirm at the bottom. As of June 8, 2021 Purpose This Interim Guidance for Office-Based Work during the COVID-19 Public Health Emergency (“Interim COVID-19 Guidance for Office-Based Work”) was created to provide businesses and entities that operate in office spaces and their employees and contractors with precautions to help protect against the spread of COVID-19 as their businesses reopen or continue to operate. This guidance addresses business activities where the core function takes place within an office setting. This guidance may apply – but is not limited – to businesses and entities in the following sectors: Professional services, nonprofit, technology, administrative support, and higher education administration (excluding full campus reopening). Please note that these guidelines may also apply to business operating parts of their business functions under different guidelines (e.g. front office for a construction company). This guidance does not address medical offices, such as doctors’ offices or dentists’ offices. This guidance also does not address building owners/managers and their employees or contractors. For more information on building management, see, “Interim COVID-19 Guidance for Commercial Building Management.” Owners and operators of offices are authorized to require masks and six feet of social distancing for employees within their establishments or adhere to DOH guidance, consistent with the Centers for Disease Control and Prevention’s (CDC) “Interim Public Health Recommendations for Fully Vaccinated People.” If choosing to adhere to CDC guidance, offices generally do not congregate patrons or operate above the State’s social gathering limits, and must follow applicable guidelines for masks, distancing, and capacity as outlined in New York State’s guidelines on Implementing CDC Guidance. -

All rights reserved. 7,500 copies of this public document were printed at a cost of $.000 per copy. • REC 3.40 11/1/2013 Introduction It is often said that the three most important factors in making a home buying decision are “location,” “location,” and “location.” Other than “location,” the single most-important factor is probably the size or “square footage” of the home. Not only is it an indicator of whether a particular home will meet a homebuyer’s space needs, but it also affords a convenient (though not always accurate) method for the buyer to estimate the value of the home and compare it to other properties. Although real estate agents are not required by the Real Estate License Law or Real Estate Commission rules to report the square footage of properties offered for sale (or rent), when they do report square footage, it is essential that the information they give prospective purchasers (or tenants) be accurate. At a minimum, information concerning square footage should include the amount of living area in the dwelling. The following guidelines and accompanying illustrations are designed to assist real estate brokers in measuring, calculating and reporting (both orally and in writing) the living area contained in detached and attached single-family residential buildings. -

KINETAIR: INTERACTIVE STAIRS with MULTIPLE FUNCTIONS 371 the Fabrication Design
KINETAIR: INTERACTIVE STAIRS WITH MULTIPLE FUNCTIONS JIE LIU1, HONGTAO MA2, NING TANG3, WEIGUO XU4 and DAN LUO5 1,2,3,4,5Tsinghua University [email protected] [email protected] [email protected] [email protected] [email protected] Abstract. Kinetair is an interactive stairs prototype which could change its appearance according to the surrounding conditions, providing a diversity of functions, such as stairs, exhibition walls, furniture and so on. This research is based on the Interactive Architecture theory, integrating with digital fabrication technology. This paper will illustrate the origin of the concept, the concept development process, the fabrication process and the various possible application of Kinetair. This experiment evokes us to rethink the fundamental meanings of the architecture components in a brand new perspective, and stimulates designers to explore the new features of conventional constructions with cutting-edge technologies. Keywords. Interactive stairs; stair design; kinetic structure; dynamic design; adaptive form. 1. Introduction Stairs, as a common elements of architecture, allows people to complete the transition between different levels, encouraging the people’s activities to jump out from the horizontal spaces into the vertical spaces, thus increasing the complexity and the hierarchy of the architecture. As the stairs were primarily designed to avoid a slope, thus for hundreds of years, people aimed on its functional attribute above other characteristics until the Renaissance, when Michelangelo designed the Laurentian Library. In this design, the stairs were first liberated from the cloaked corner of the building and turned into a sculpture-like design placed in the middle of the building’s hall, acting like the ornament of the building, showing the aesthetic performance of the stairs. -

UDC Dimensional Standards This document includes basic information regarding lot dimensions, setback and other lot standards. For full, up-to-date, information, you may wish to refer to the Unified Development Code (NCC Code, Chapter 40) Article 4 available online at: http://czo.nccde.org/ This Section contains the basic district standards applicable to all uses. Table 40.04.110 contains intensity, lot, bulk and exterior storage standards. These standards may be modified by the Department pursuant to Article 26. A. Minimum open space ratio. For residential subdivisions of five (5) lots or less open space shall not be required. Protected resource land shall be preserved by conservation easements. For major land development plans, all protected resources shall be in open space and none shall be permitted on any residential lots. B. Minimum site area. Minimum site area is the minimum area required before any new uses recognized by this Chapter may be permitted in the zoning district. No land shall be rezoned unless the proposed zoning district meets minimum site area requirements. In determining minimum site area requirements, contiguous parcels of the same zoning shall be considered in the calculation. C. Maximum building height. If there are single-family detached or single-family attached dwellings within one hundred (100) feet of a property line of the parcel to be developed with a building over fifty (50) feet, the required front, street, side or rear yards adjacent to those dwellings shall be at a minimum equal to the height of the proposed building. D. Minimum lot area. The minimum lot area requirement must be met exclusive of protected resources, and for lots less than one (1) acre, exclusive of required bufferyards.
