Solicitation Document L - UNIFORMAT II - Level 3 Detail Reference Guide.xlsx

This document is a UNIFORMAT II Level 3 Detail Reference Guide developed by the GSA Office of Design and Construction to standardize work breakdown structure (WBS) cost element organization for construction projects. The guide establishes a hierarchical classification system with three levels (L1, L2, L3) for organizing construction costs, beginning with major categories such as Substructure (A), Shell (B), Interiors (C), Services (D), Equipment & Furnishings (E), Special Construction & Demolition (F), Sitework (G), and Indirect Costs (Z). Each category is further subdivided into increasingly specific cost elements with defined units of measure (SF for square feet, CY for cubic yards, EA for each, LF for linear feet, etc.) and quantification methodologies to facilitate consistent cost estimation and project budgeting.

The guide provides detailed classifications for structural components (foundations, basement construction, superstructure), exterior systems (walls, windows, doors, roofing), interior elements (partitions, doors, stairs, finishes), building services (conveying systems, plumbing, HVAC, fire protection, electrical), equipment and furnishings, special construction systems, site work, and indirect cost categories including design contingency submissions at various project phases (feasibility, PDS, concept, design development, 65% CD, 90% CD, 100% CD), general conditions and profit allocations for single and multi-phased projects, escalation to construction mid-point, and contingency reservations. This standardized reference guide is applicable to the 1800F Street GSA Building renovation project, which involves significant structural renovation, tenant improvements, building envelope repairs, and courtyard reactivation requiring comprehensive cost tracking and WBS organization.
