Today’s modern mid rise and high rise luxury condominiums and apartment buildings offer numerous amenities to attract potential owners. They can offer spectacular vistas through floor to ceiling walls of glass, high end finishes on the floor, gourmet style kitchens with all the modern features one could ever want, and a master bedroom suite that offers a tranquil and quiet place to escape. In these building types, elevators become a necessary component for vertical circulation to access the floors. For those residences that are adjacent to the elevator equipment room or the elevator hoistway, the noise and vibration caused by the operation of the elevator can be a potential source of sound intrusion. Because today’s buildings are constructed with lightweight materials, and because there is a need to generate maximum useable square footage, sound transmission issues are compounded. All this combined can result in unsatisfactory living conditions for tens of thousands who live in condominiums or apartments.
Concrete masonry units (CMU) have long been considered the ideal backup material for brick facing; however, because of increasing installation costs, CMU backup systems have given way to metal stud backup systems. Brick veneer with metal stud backup walls, because they are a very cost effective and versatile wall assembly, are very commonly seen in today’s commercial buildings. The original exterior metal stud wall systems of the 1970’s were simple. They consisted of metal studs at 16 or 24 inches on center, with fiberglass batt insulation having an integral vapor barrier placed in between. Gypsum board sheathing was placed on each side, and 15 pound felt paper was installed over the exterior sheathing. This system eventually would fail and allow air and moisture to enter the building, degrading the insulation and thus the R-Value of the wall, not to mention causing other significant problems.
A building's wall system must constantly fight the invasion of rain, air, vapor and thermal attacks.The wall's ability to provide a barrier to each of these elements relies upon the use of appropriate materials, installed in the correct sequence. There is no such thing as a perfect wall system; however, a wall system that performs with greater efficiency using new efficient materials is achievable.

几乎每商业和公共建筑，无论是写字楼，体育场馆，礼拜场所，或学校建筑物，包含了护栏系统。护栏系统安装用于建筑物的居住者提供安全和保护，被放置在或靠近外边缘， 的楼梯，坡道，楼梯平台，平台，阳台和屋顶进入的地区。They will also be found at the perimeter edge of any opening or accessible surface, such as an opening for a stairway, or at a location where operating conditions require limited access to a designated area in order to guard against accidental falls.
Demolition projects can range from small, simple jobs to complicated undertakings that require sophisticated and detailed planning. Site conditions can vary significantly, and there is always a degree of imprecision to the wrecking of the building itself. For typical building demolition and site improvements the most common procedure is to use heavy mechanical equipment such as wrecking balls, excavation hoes, grapples, pulverizers, crushers, and hydraulic breakers and shears. Several factors need to be considered prior to and during demolition, including the scheduling of demolition activities, protecting the site (especially important with occupied structures), and dealing with hazardous materials.
I recently had the opportunity to visit Bing Thom’s much talked about and long-awaited Arena Stage renovation and expansion project in Washington, D.C. With slightly more than two years of construction completed, the $125 million, 200,000 square foot project is in the final stages and is due to open its doors on schedule for the inaugural 2010/11 theater season later this fall.
拆迁项目的范围可以从小型，简单的工作到需要复杂和详细规划复杂的事业。立地条件可以显著变化，总有建筑物本身的击毁一定程度的不精确性。对于典型的建筑物拆除和现场改善最常见的程序是使用重型机械设备如击毁球，挖掘锄头，抓斗，粉碎机，破碎机，和液压破碎机和剪切机。有几个因素需要之前和拆卸期间被考虑，包括拆除活动的调度，保护位点（与占用结构尤其重要），以及处理有害物质。

The residents and businesses of Columbus, Ohio have another chance to capitalize on an incredible opportunity. The Columbus Dispatch recently reported that NASCAR racer Jeff Gordon will team up with Arshot Investment Corp to propose plans for a racing facility at the existing vacant Cooper Stadium. Cooper Stadium has been vacant since the Columbus Clippers moved to their new home at Huntington Park at the end of the 2008 season. There is no doubt this project will provide the economic jump-start that this part of town needs.
已经提供43年服务时，冰场在州立鲍灵格林大学是校园的热门地点，供应的BGSU的学生和教师，以及当地的市政社区。目前由康乐及健康的部门工作时，冰场最初设计于1965年，包含了主要的冰盖，在200’ 大小的X 85’ 。还设有一个工作室冰盖为80’ ×40’ 和卷曲冰盖在150’ X 57’ ，以及一个休息室和其他配套设施。
在1979年年初，制造商和安装程序的新堪萨斯城凯悦酒店建议修改为支持的人行天桥系统的连接细节中庭钢。最初的设计被认为是制造成本昂贵和安装问题。工程师的回应是提供制造厂的建议的初步草图，而不执行基本计算。这些草图被送回制造者，谁承担这些是最终批准施工图。 The revised and ill-fated connection detail was put into production and installed. In 1981, the Kansas City Hyatt skywalk collapsed, causing the deaths of 114 people and injuring more than 200. The ensuing investigations concluded that the fault lay in the engineer's failure to properly review shop drawings and provide adequate communications between the structural engineer and the fabricator of the structural steel for the atrium and skywalk.

With the advent of high rise buildings, fire safety has been of particular concern for architects over the last 100 years. Architects must understand the basics of fire and smoke and the risks associated with creating tall buildings. The spread of toxic smoke that results from fires has been shown to often cause more damage than the fire itself, and it is responsible for more injuries and fatalities.
