25、semantics to be exchanged in building information models to support various business use cases throughout architec-ture, engineering, construction, and operations projects. The project committee responsible for developing the NBIMS-USTMis a committee of the buildingSMART (2013) alliance, a council o

26、f the National Institute of Building Sciences.The NBIMS-USTMestablishes the standard process to develop the NIBS standard. The process includes four phases.1. ProgramDefines information exchange requirements that may be standardized by developing process models and defining specifications and busine

27、ss rules for each exchange. An information exchange is the transfer of data in context between various entities along the cast-in-place (CIP) concrete supply chain (that is, from the architect to the struc-tural engineer). In this phase, a process model that identi-fies the required tasks and where

28、the information exchanges take place in the project lifecycle, as well as the entities such as engineers, reinforcing bar detailers who develop or use information, and software applications, which are the senders and recipients of these exchanges, is developed. The information exchanges are defined

29、by exchange models that specify the functional requirements (content and format) of data exchanges to be implemented. When the process models and exchange models are combined, they form an information delivery manual (IDM). This IDM serves as the overall functional requirements specification for one

30、 or more exchanges.2. DesignDevelops exchange requirement models and generic model view definition (MVD).3. ConstructDevelops software implementation specifi -cations for MVD and facilitates product testing and certifica-tion of information exchanges.4. DeployProvides generic and product-specific bu

32、on among various project entities throughout a project lifecycle. Specifically, a process model that identifies the typical workflows during engi-neering design, planning, and site production of concrete is developed. It identifies when information is shared between disciplines at different stages o

33、f projects. The tasks and information exchanges that make up the process model are defined.CHAPTER 2DEFINITIONSbuilding information modelingprocesses and tech -nology that use a digital representation of the physical and functional characteristics of a project.exchange modelsdescription of the infor

35、LIVERY MANUAL OVERVIEW3.1BackgroundAn information delivery manual (IDM) defines exchange requirements in the context of reference industry processes. IDMs are defined by end users and practicing professionals to support the process in which they are expert. The resulting IDM serves to define the exc

36、hange requirements for one or more building information modeling (BIM) transactions.The IDM is focused on end-user exchange requirements supporting a given set of workflows. The exchange require-ments are captured by developing a process model that defines the context of the workflows of interest. T

37、he process model identifies the sets of use case exchanges being addressed, the tasks involved in each phase of the project, and the exchange requirements that will enhance the workflow. The various components of the IDM capture the user needs and specifi-cation of the exchanges in a form that can s

38、erve as the func-tional requirements for the technical exchange specification, called a model view definition (MVD). Thus, the IDM is developed by users to specify what they need for a target workflow, to be translated later by the MVD into computer-implementable code.This report defines the functio

39、nal data exchange require-ments and workflow scenarios for exchanges among all the entities involved in the cast-in-place (CIP) concrete supply chain during each phase of a project. There are a wide variety of CIP concrete elements used in construc-tion projects, including different types of footing

40、s, beams, columns, walls, slabs, ramps, corbels, piles, and piers. These are mostly used as part of the structural system of facilities. The different elements are often designed and produced by separate business entities that include formwork design and American Concrete Institute Copyrighted Mater

41、ial www.concrete.org2 INFORMATION DELIVERY MANUAL (IDM) FOR CAST-IN-PLACE CONCRETE (ACI 131.1R-14)erection, reinforcement detailing, fabrication and placement, design of concrete mixture proportions, placing, testing and curing, and concrete finishing. Moreover, CIP concrete, as a fundamental buildi

42、ng system, interacts with many other aspects of a building in the following ways:(a) Concrete walls might be connected to steel or precast concrete beams and precast concrete or composite slabs, and sometimes to concrete columns.(b) Concrete may encase or otherwise be connected to steel, creating co

43、mposite members, including composite beams, columns, shear walls, slabs, and braces.(c) Mechanical, electrical, and plumbing (MEP) products cross CIP concrete elements.(d) The site excavation plan and execution schedule are important for design and execution of concrete foundations.There are 16 diff

44、erent disciplines identified in the process model developed in this report (Table 3.1a).Exchanges are defined for six different phases of a project (Table 3.1b). To accommodate the diversity and variety of disciplines involved, efficient communication and collabora-tion of the different disciplines

45、during each project phase is required. Designers and producers of CIP concrete elements may choose to use a variety of software tools to generate information. Hence, enabling efficient interdisciplinary coordination and collaboration requires exchange of infor-mation between different software platf

46、orms in model and nonmodel forms. This report identifies and documents the information items that each discipline involved in design, planning, production, and site construction of CIP concrete needs to share with other disciplines at different stages of the projects.Workflows within the CIP concret

47、e supply chain are not standardized, but are tuned dynamically to reflect what is most appropriate for a given project and stage. Some processes might vary based on the selected delivery method and specific contract terms designated for a project. The definitions of workflows in this report are tied

48、 into an overall process and a typical illustrative schedule, not as a prescrip-tive process. The process model is laid out to provide a structure for addressing different use cases of information exchange; they are not intended to be used as a prescriptive process.3.2 Information delivery manual hi

49、erarchyFigure 3.2 illustrates the hierarchical structure used to develop an information delivery manual (IDM), which includes the following.a) Process models (Appendixes A through D): this is defined for the general processes identified for cast-in-place (CIP) concrete construction projects. The process models identify the tasks carried out and the typical phase of design in which they are carried out. They also define the exchanges required to support the flow of information needed to accomplish those tasks; these are called exchange models. The ful
