About 60 percent of the homes were built during the s and s, with the rest constructed between the s and early s. All homes in the sample had wood exterior wall framing, and specifications and standards book did not use structural sheathing for wall bracing. While construction quality was not the primary determinant of construction performance on an overall population basis, it is a significant factor that should be addressed by proper inspection of key components related to the performance of the structure, particularly connections. The short-period ground motion typically used in the design of light-frame structures had no apparent correlation with the amount of damage observed in the sampled homes, although a slight trend with respect to the long-period ground motion was observed in the data.
While the product class is relatively new in the United States, it appears to be gaining acceptance. Since specifications and standards book seismic design theory implies that more bracing is better, the Northridge findings are fundamentally challenging, yet offer little in the way of a better design theory. Although specifications are usually issued by the architect 's office, specification writing itself is undertaken by the architect and the various engineers or by specialist specification writers. For example, in hurricane-prone areas such as Florida, standard concrete masonry construction dominates the market where its performance in major hurricanes has been favorable when nominally reinforced using conventional practices. Completion and delivery. Therefore, it is essential that housing performance be understood objectively as a prerequisite to guiding rational design and construction decisions.

Although building codes are legally a Modern construction police power, most states allow local political jurisdictions to specifications and standards book or modify building codes to suit their "special needs" or, in a few cases, to write their own code. Specifications can be either "performance-based", whereby the specifier restricts the text to stating the performance that must be achieved by the completed work, "prescriptive" where the specifier states the specific criteria such as fabrication standards applicable to the item, or "proprietary", whereby the specifier indicates specific products, vendors and even contractors that are acceptable for each workscope. Construction specifications in Egypt[ edit ] Specifications in Egypt form part of contract documents. The small percentage of surveyed homes about 2 percent that experienced moderate to high foundation damage was located in areas that endured localized ground effects i.

Although many Architects find the rather voluminous commercial style of specifications too lengthy for most residential projects and therefore either produce more abbreviated specifications of their own or use ArCHspec which was specifically created for residential projects. While the product class is relatively new in the United States, it appears specifications and standards book be gaining acceptance.
Some key recommendations on wind-resistant design and construction include the following: Significant benefits in reducing the most Modern construction forms of hurricane damage can be attained by focusing on critical construction details related to the building envelope, such as correct spacing of roof sheathing nails particularly at gable endsadequate use of roof tie-downs, and window protection in the more extreme hurricane-prone environments along the southern U.
Instead, wood let-in braces, Portland cement stucco, and interior wall finishes of plaster or gypsum wallboard provided lateral racking resistance. Several standards are devoted to the measurement, classification, and grading of wood properties for structural applications, as well as virtually all other building materials, including steel, concrete and masonry.
As implied by any rational interpretation of a building code or design objective, safety implies the existence of an acceptable level of risk.
Overall, the damage relative to key design features showed no discernible pattern, implying great uncertainties in seismic design and building performance that may not be effectively addressed by simply making buildings stronger.
On a national scale, several homes are subjected to extreme climatic or geologic Modern construction in any given year. Examples include metal plate-connected wood trusses, wood I-joists, laminated veneer lumber, plywood, oriented strand board OSBglue-laminated lumber, and parallel strand lumber.
Construction Contract Administration Practice Guide[ edit ] The CSI Construction Contract Administration Modern construction Guide CCAPG provides a detailed discussion of the process of successfully delivering specifications and standards book construction project, focused on the roles of the various participants in the process and their relationship to one as described by contractual requirements in standard construction contracts.
While available resources and the economy continue to play a significant role, building codes, consumer preferences, and alternative construction materials are becoming increasingly important factors. The responsibilities of team members are set forth in the contract documents and can differ depending on the method of project delivery selected for a project, the CCAPG describes these different responsibilities and recommendations for successful execution of a project.
Certified Construction Product Representative CCPR [ edit ] First awarded inThe CCPR demonstrates an in-depth understanding of the construction process, the information needs of designers and contractors, and a superior ability in meeting those needs through effective communication of construction product properties and functions.
Most homes were one-story structures with nominally reinforced masonry walls, wood-framed gable roofs, and composition shingle roofing.
At speeds of to mph over a relatively large populated area, Hurricane Andrew was estimated to be about a year return-period event see Figure 1. In part, this apparent trend may be attributed to changing perceptions regarding housing performance in high-risk areas.
The original listing of specification divisions was based on the time sequence of construction, working from exterior to interior, and this logic is still somewhat followed as new materials and systems make their way into the construction process.
The CDT credential was initially offered as a certificate, and was transitioned to a professional certification in April Masonry wall construction with nominal reinforcement less than that required by current engineering specifications and roof tie-down connections performed reasonably well and evidenced low damage frequencies, even through most homes experienced breached envelopes i.
The benefits of cold-formed steel include cost, durability, light weight, and strength. Ultimately, the significance of these types of defects must be viewed from the perspective of known consequences relative to housing performance and risk. The PDPG presents an overview of the process needed to conceive, design, construct, and maintain a construction project.
The CSPG serves as a guidebook to the preparation, organization, and coordination of construction documents and focuses on the written description of a specifications and standards book and how that description relates to the other construction documents, the best practices for product selection and the roles and responsibilities of the parties to the process of design and construction.
This Guide describes the many parts of that process and specifications and standards book inter-related roles of the various participants in the process.
