    Significance and Use

    Significance:

    The application of elements (see 3.2.1 and Terminology E 833) to the description and the summary and analysis of building construction cost provides a consistency, commonality, and utility through all stages of design that other forms of estimate presentation do not.

    This practice describes a simple format for elemental cost analysis presentation that is both valuable and informative when used during the various design stages of construction development.

    UseUsers include owners, developers, contractors, cost professionals, estimators, architects, engineers, quantity surveyors, facility managers, and others involved in property development, construction, maintenance, and management.

    ReportingCost reports structured by elements provide estimates, summaries, and analyses by applying Cost to Function. This application works whether the approach is Design to Cost or Cost to Design. Value analysis is greatly assisted through the allocation of estimated cost to elements.

    ControllingComparison of progressively more detailed estimates is simplified where cost is allocated to appropriate elements regardless of design or specification, permitting efficient review and checking of new estimates. Design estimating using elements allows for benchmarking and the setting of cost limits (baseline) for a building design from the outset, and also permits the establishment of an elemental cost plan (see 3.2.2). Baseline records and cost plans are accessed and compared with current reports.

    RecordingHistoric and baseline cost records are easily kept for all forms of building construction, and in a format that can be used for the planning and design of future projects.

    Other UsesElemental summaries and analyses are equally useful in forensic estimating and in quantitative risk analysis.

    Relationship to Trade EstimatingTraditional trade (or construction) estimating summarizes cost to a product, or trade classification. This is valuable when construction work has been fully specified or contracted, but is less so through the planning and design stages. The two systems (trade and elemental) are compatible in that they both relate to the same end product, for example, a building; they differ solely in the way cost is aggregated. Each estimate form can be converted to the other by coding or allocating each construction component to an appropriate trade/product division or element. During design evolution, changes in design and specification can make trade estimates difficult to compare with previous or other, or both, estimates and so can hinder the process of cost control during the design phase.

    Additional Narrative InformationWhile costs presented in these formats are descriptive in themselves they do not tell the full story of a projects design. Narrative description of the construction work should also be an integral part of any complete presentation. Reference and description of this narrative form can be found in Practice E 1804, and in Classification E 1557 Appendix X3Preliminary Project Description (PPD).

    A detailed description of the presentation formats now follows. These descriptions are provided in eight sections, each intended to aid understanding of a particular facet of the formats:

    1. Scope

    1.1 This practice covers the concurrent use of relevant ASTM standards for the preparation of elemental cost estimates, summaries, and analyses and specifically their presentation in a concise, consistent, and logical manner.

    1.2 While the style and directions use construction terms applied to buildings, the principles apply equally well to other forms of construction where appropriate elemental classifications exist.

    1.3 This practice is not an estimating manual, nor is it a guide to the skills and knowledge required of an estimator or other cost professional.

    Note 1—The skills and knowledge acquired by a trained and experienced estimator are essential to the successful application of any elemental presentation format. They are the foundation of any estimate and the underpinning knowledge required when applying the elemental technique.
