GSA CBS Submittal Matrix (2025) - Version 1.0 GSA CBS Submittal Matrix (2025) - Version 1.0

The submittal matrix is provided to document the baseline submittal requirements for the four project delivery methods and funding codes.

Project teams must still provide the standard of care for a fully constructible set of documents.

This matrix identifies items that GSA requires to validate that the project is moving forward while meeting the requirements of CBS. Additional submittal requirements may be included in the project contract.

Per The Architectural Barriers Act Accessibility Standard (ABAAS) (42 U.S.C. § 4152):

❏ NARRATIVE: Further develop the ACCESSIBILITY PLAN to address key accessibility issues significantly impacting the concept design as follows:

❏ SITE: Identify constraints and strategies to include ramps, traffic conflicts, pedestrian crossings, changes in grade and locations of accessible parking and drop-offs, signage and main entrance identification and visibility.

❏ BUILDINGS AND ALTERATIONS: Identify constraints/challenges due to building type and scoping of project. Reference both public and staff spaces and occupancies. Describe applicable accessibility codes to be enforced. Describe accessible path of travel obligations resulting from changes to primary function areas (ABAAS F202.4). Identify any areas intended to meet adaptability vs accessibility.

❏ HISTORIC PRESERVATION: Identify any ABAAS exceptions (see F202.5) and discuss any mitigation measures to be taken to make facility as accessible as possible.

❏ DRAWINGS: Refine drawings of all required Path of Travel elements including site arrival points, accessible routes, accessible parking, clear floor areas and other accessible elements.

Highlight areas of special access consideration. Indicate Pros and Cons for each option.

❏ If the POR is updated, then update the statement to reflect relevant findings and changes.

Identify strategies and elements in the drawings and reference in the statement.

❏ Update project risk register.

❏ Highlight relevant responses to previous submission comments.

❏ Provide list of applicable codes.

❏ Provide assessment of hazardous materials

❏ BIM Execution plan updated (per 2024 GSA BIM CDX and COBie Standard).

❏ Reality Capture documentation (for an existing building, or historic site, and if required by scope) - e.g. Laser Scans, existing conditions model, 360 photos, etc.)
