Classification Of Building Related Sitework Per ASTM UNIFORMAT II Standard

Attention: open in a new window. PDFPrintE-mail

The classification of building related sitework is an integral and key part of the ASTM UNIFORMAT Standard E1557. It provides all project stakeholders with a common point of agreement on sitework elements.

The classification was designed to meet the following requirements:

  • applies to any building type, although it is designed for commercial buildings
  • allows for specific details required for describing specialized buildings
  • separates the classification of building elements from the classification of buildingrelated
  • sitework
  • relates to other elemental classifications such as the original UNIFORMAT and those of the Canadian Institute of Quantity Surveyors (CIQS) and the Royal Institute of Chartered Surveyors (RICS-UK)

UNIFORMAT II is not intended to classify elements of major civil works. Buildings, however, are usually accompanied by roads, utilities, parking areas, and other nonbuilding features.

The UNIFORMAT II classification of building related sitework is provided exclusively for buildings construction support so users don't need multiple elemental classifications for what is primarily a buildings project.

Classification Of Building Related Sitework


The ASTM E1557 "Standard Classification for Building Elements and Related Sitework - UNIFORMAT II" provides a common structure linking the building program, specifications, and estimates.

Its integration in the design process results in improved communications and coordination among all project participants, an accelerated design, and significantly increased productivity.

The classification provides the Project Manager with an essential tool to control project scope, cost, time and quality.
