Scope1.1This classification covers bridge elements and related approach work. Elements, as defined here

3、, are major componentscommon to most bridges. Elements usually perform a given function, regardless of the design specification, construction method,or materials used. This classification serves as a consistent reference for analysis, evaluation, cost estimating, and monitoringduring the feasibility

4、, planning and design stages of bridges. It also enhances reporting at all stages from feasibility and planningthrough the preparation of working documents, construction, maintenance, rehabilitation, and disposal.1.2This classification applies to bridges and related approach work. It excludes specia

5、lized structures such as signs and signalsrelated to general highway use, but it does include bridge parapets, medians, drainage, and barriers needed to lessen vehicularimpact.1.3This classification is similar to the Classification E1557.1.41.1 This standard establishes a classification of bridge el

6、ements within the UNIFORMAT II family of elemental classifications.It covers most highway bridges, railroad bridges, and pedestrian bridges.1.2 UNIFORMAT II classifications have an elemental format similar to the original UNIFORMAT2building elementalclassification. However, the title UNIFORMAT II di

7、ffers from the original in that it now takes into consideration a wide range ofconstructed entities that collectively form the built environment.1.3 Elements, as defined here, are major physical components that are common within constructed entities. Elements performtheir given function(s), regardle

8、ss of the design specification, construction method, or materials used.1.4 This elemental classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility,planning, and design stages when constructing bridges.1.5 Using UNIFORMAT II elemental classificat

24、lassification E1557. This classificationdescribes bridge elements that are major components of most highway, railroad, and pedestrian bridges. The elementalclassification is the common thread linking activities and participants in a bridge project from initial planning through operations,maintenance

25、, and disposal.NOTE 1As this classification refers solely to permanent, physical parts of any construction, two additional classifications, Classifications E2083 andE2168, need to be included when calculating construction cost. These standards provide for the inclusion of construction enabling, temp

Procedures for reporting all these figures are described in Practices E1804 and E2514 and Classification E2516. While these threelatter st

27、andards were primarily written for building construction, they are nonetheless appropriate and readily applied to other forms of construction aswell.4.2 The Users of Bridge UNIFORMAT II Include:4.2.1 Financial and InvestmentTypically owners, developers, bankers, lenders, accountants, and financial m

28、anagers.4.2.2 ImplementationPrimarily project managers; facilities programmers; designers, including engineers; and project controlsspecialists, including cost planners, estimators, schedulers, specification writers, and risk analysts.4.2.3 Facilities ManagementComprising property portfolio managers

29、, operating staff, and maintenance staff.4.2.4 OthersPublic officials, manufacturers, educators, students, and other project stakeholders.4.3 Apply This Classification When Undertaking the Following Work on Bridges:54.3.1 Financing and Investing:4.3.1.1 Structuring costs on an elemental basis for ec

31、ngs.4.3.2 Implementing:4.3.2.1 Cost Modeling, Cost Planning, Estimating and Controlling Project Time and Cost During Planning, Design, andConstructionUse the bridge UNIFORMAT II classification to prepare budgets and to establish elemental cost plans before designbegins. Project managers and project

32、controls specialists use these cost plans against which to measure and control project cost,and quality, and to set design-to-cost targets.4.3.2.2 Conducting Value Engineering WorkshopsConducting value engineering workshops (Practices E1699 and E2013).Use this classification as a checklist to ensure

33、 that alternatives for all elements of significant cost in the bridge project are analyzedin the creativity phase of the job plan. Also, use the elemental cost data to expedite the development of cost models for bridgesystems.4.3.2.3 Developing Initial Project Master SchedulesSince projects are esse

34、ntially built element by element, UNIFORMAT IIclassifications are an appropriate basis for preparing construction schedules at the start of the design process. Project managers andproject controls specialists use these time plans against which to measure and control project time (Practice E2691), an

35、d to setmilestone target dates.4.3.2.4 Performing Risk AnalysesSimulation (Guides E1369 and E2506) is one technique for developing probabilitydistributions of bridge costs when evaluating the economic risk in undertaking a bridge project. Use individual elements and groupelements in this classificat

36、ion for developing probability distributions of elemental costs. From these distributions, build upprobability distributions of total costs to establish project contingencies (Practices E1946 and E2168) or to serve as inputs to aneconomic analysis.4.3.2.5 Structuring Preliminary Project Descriptions

37、 During the Conceptual Design PhaseThis classification facilitates thedescription of the scope of the project in a clear, concise, and logical sequence for presentation to the client; it provides the basisfor the preparation of more detailed elemental estimates during the early concept and prelimina

38、ry design phases, and it enhancescommunication between designers and clients by providing a clear statement of the designers intent.4.3.2.6 Coding and Referencing Standard Details In Computer-Aided Design SystemsThis classification allows a designer, forexample, to reference an assembly according to

39、 this classifications element designations and build up a database of standarddetails. This is particularly appropriate to design modeling and building information modeling (BIM) applications.4.3.3 Managing Facilities:4.3.3.1 Recording and writing property condition assessment reports in a structure

40、d way, using UNIFORMAT II classifications,provides for a consistent, accessible, and searchable database of real property inventory.4.3.4 Other Activities:4.3.4.1 Structuring cost manuals and recording construction, operating, and maintenance costs in a computer database. Havinga cost manual or comp

41、uter database in an elemental format assists the preparation of an economic analysis early in the design stageand at a reasonable cost.5. Basis of Classification5.1 The framework in Fig. 1 shows how bridge structures and related approaches fit with the rest of the built environment. Thisclassificati

42、on does not include general road features such as pavements, drainage structures, and noise walls.5.2Criteria for the ClassificationThe selected elements are grouped according to the following criteria:5.2.1The classification is applicable to any type of bridge.5.2.2The classification is consistent

43、with that used in typical costing practices.5.2.3Each individual element has a significant impact on the cost, and it usually occurs frequently.5For a more comprehensive discussion of the uses of UNIFORMAT II, see Bowen, Charette, and Marshall, UNIFORMAT IIARecommended Classification for BuildingEle

47、 Heavy (Civil) Entities.5.1.1 This bridge classification is applicable to most types of highway, railroad, and pedestrian bridges crossing over highways,railroads, walkways, and waterways. The classification includes slab bridges; beam/girder bridges; truss bridges; true and tied-archbridges; cable-

48、stayed bridges; and suspension bridges. The classification does not include the following movable bridge types:draw bridges; lift bridges; and bascule bridges.5.2 The classification is consistent with typical costing practices used at the conceptual design phase.5.3 Each element has a significant im

49、pact on the cost, and it usually occurs frequently.5.4 Each element performs a specific function.5.5 Table 1 represents the classification of bridge elements into three hierarchical levels: Level 1 - Major Group Elements, Level2 - Group Elements and Level 3 - Individual Elements. The Major Groups are listed in the normal chronological order ofconstruction. divides the classification of bridge elements into three hierarchical levels: Level 1Major Group Elements, Level2Group Elements, and Level 3Individual Elements.
