Significance and Use
4.1 This standard builds on the concepts and organizational framework established in Classification . This classification describes transportation surface elements that are major components of most vehicular transportation surfaces. The elemental classification is the common thread linking activities and participants in a transportation surface project from initial planning through operations, maintenance, and disposal.
Note 1: As this classification refers solely to permanent, physical parts of any construction, two additional classifications, Classifications and , need to be included when calculating construction cost. These standards provide for the inclusion of construction enabling, temporary, and risk mitigation cost figures. Procedures for reporting all these figures are described in Practices and and Classification . While these three latter standards were primarily written for building construction, they are nonetheless appropriate and readily applied to other forms of construction as well.
4.2 The users of transportation surface UNIFORMAT II include:
4.2.1 Financial and Investment—Typically owners, developers, bankers, lenders, accountants, and financial managers.
4.2.2 Implementation—Primarily project managers; facilities programmers; designers, including engineers; and project controls specialists, including cost planners, estimators, schedulers, specification writers, and risk analysts.
4.2.3 Facilities Management—Comprising property portfolio managers, operating staff, and maintenance staff.
4.2.4 Others—Public officials, manufacturers, educators, students, and other project stakeholders.
4.3 Apply This Classification When Undertaking the Following Work on Transportation Surface Projects:
4.3.1 Financing and Investing:
184.108.40.206 Structuring costs on an elemental basis for economic evaluations (Guide and Practices , , , , , and ) early in the design process helps reduce the cost of early financial analysis and can contribute to substantial design and operational savings before decisions have been made that limit options for potential savings.
220.127.116.11 Cost Modeling, Cost Planning, Estimating and Controlling Project Time and Cost During Planning, Design, and Construction—Use the transportation surface UNIFORMAT II classification to prepare budgets and to establish elemental cost plans before design begins. Project managers and project controls specialists use these cost plans against which to measure and control project cost, and quality, and to set design-to-cost targets.
18.104.22.168 Conducting Value Engineering Workshops—Conducting value engineering workshops (Practices and ). Use this classification as a checklist to ensure that alternatives for all elements of significant cost in the transportation surface project are analyzed in the creativity phase of the job plan. Also, use the elemental cost data to expedite the development of cost models for transportation surface systems.
22.214.171.124 Developing Initial Project Master Schedules—Since projects are essentially built element by element, UNIFORMAT II classifications are an appropriate basis for preparing construction schedules at the start of the design process. Project managers and project controls specialists use these time plans against which to measure and control project time (Practice ), and to set milestone target dates.
126.96.36.199 Performing Risk Analyses—Simulation (Guides and ) is one technique for developing probability distributions of transportation surface costs when evaluating the economic risk in undertaking a transportation surface project. Use individual elements and group elements in this classification for developing probability distributions of elemental costs. From these distributions, build up probability distributions of total costs to establish project contingencies (Practice and Classification ) or to serve as inputs to an economic analysis.
188.8.131.52 Structuring Preliminary Project Descriptions During the Conceptual Design Phase—This classification facilitates the description of the scope of the project in a clear, concise, and logical sequence for presentation to the client; it provides the basis for the preparation of more detailed elemental estimates during the early concept and preliminary design phases, and it enhances communication between designers and clients by providing a clear statement of the designer’s intent.
184.108.40.206 Coding and Referencing Standard Details in Computer-Aided Design Systems—This classification allows a designer, for example, to reference an assembly according to this classification’s element designations and build up a database of standard details. This is particularly appropriate to design modeling and building information modeling (BIM) applications.
4.3.3 Managing Facilities:
220.127.116.11 Recording and writing property condition assessment reports in a structured way, using UNIFORMAT II classifications, provides for a consistent, accessible, and searchable database of real property inventory.
4.3.4 Other Activities:
18.104.22.168 Structuring cost manuals and recording construction, operating, and maintenance costs in a computer database. Having a cost manual or computer database in an elemental format assists the preparation of an economic analysis early in the design stage and at a reasonable cost.
1.1 This standard establishes a classification of transportation surface elements within the UNIFORMAT II family of elemental classifications. It covers the full breadth of vehicular transportation surfaces, from rural roads to multi-lane interstate highways.
1.2 UNIFORMAT II classifications have an elemental format similar to the original UNIFORMAT building elemental classification. However, the title UNIFORMAT II differs from the original in that it now takes into consideration a wide range of constructed entities that collectively form the built environment.
1.3 Elements, as defined here and in Classifications and , are major physical components that are common within constructed entities. Elements perform their given function(s), regardless 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 transportation surfaces.
1.5 Using UNIFORMAT II elemental classifications ensures a consistency in the economic evaluation of construction projects over time and from project to project.
1.6 UNIFORMAT II classifications also enhance reporting at all stages of a constructed entity’s life cycle—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.
1.7 This classification is unsuitable for process applications or for preparing trade estimates.
1.8 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
