About this file
This document is a Buy Clean Colorado Form for the Fort Garland Vehicle Storage Facility (VSF) project, involving the Colorado Department of Transportation (CDOT) and vega architecture, llc. The project involves constructing a new 7+1-bay Vehicle Storage Facility in Costilla County, with a focus on tracking and reporting the environmental impact of construction materials through Environmental Product Declarations (EPDs). The form details specific requirements for eligible materials including concrete, steel, glass, and asphalt, mandating that each material meet global warming potential (GWP) thresholds established by the Office of the State Architect.
The document outlines a comprehensive compliance process requiring consultants and contractors to document and verify the carbon footprint of materials used in the project. Specific material categories have predetermined GWP limits, such as 85 kg CO2 equivalent per metric ton for asphalt mixtures and 1,030 kg CO2 equivalent per metric ton for steel reinforcing bars. Participants must submit detailed documentation, including product-specific Type III EPDs, and certify compliance through signed submissions. The requirements apply to all public projects beginning solicitation on or after January 1, 2024, with contractors required to maintain and organize project EPDs in a zip folder for closeout documentation.

Instructions
| Design Submittal #: | |
| General Contractor: | |
| Consultant: | vega architecture, llc |
| Agency/Institution: | Colorado Department of Transportation |
| Project #/Title: | #23704 Ft Garland VSF |
| Date: |
This form shall be used by consultants, contractors, and agency delegates to submit eligible material information and Environmental Product Declaration (EPD) information for compliance with the Buy Clean Colorado (BCCO) Act requirements (C.R.S. 24-92-117). Products must demonstrate compliance with the Office of the State Architect's (OSA's) global warming potential (GWP) limits by demonstrating that the GWP included in each EPD is less than or equal to the OSA's GWP limit for that product category. For all public projects beginning solicitation on or after January 1, 2024, a current product-specific Type III EPD must be submitted for each eligible material purchased and installed on the project. For assemblies containing eligible material components, if the embodied carbon of each eligible material in the assembly is less than the embodied carbon limits established by OSA, then it can be reasonably assumed that the embodied carbon of the assembly is compliant with the BCCO Act.
Consultants should fill out Column G on the 'Instructions' sheet to indicate which materials apply to the project. Consultants shall fill out the 'EPD Design Submittal' sheet and certify that they have met the minimum requirements by signing the 'EPD Design Submittal' and 'Final Sign-Off' tables. Contractors shall review the information provided by the consultant and shall complete the 'EPD Construction Submittal' sheet for each eligible material procured for the project. Contractors shall also complete the 'Transportation (A4)' table for all eligible materials procured over 100 miles from the project site. Contractors shall maintain and organize all project EPDs to be submitted in a zip folder as part of the closeout documentation. Eligible product-specific EPDs must reference the associated Product Category Rule (PCR), indicate third-party verification (Type III), and reference all ISO Standards (ISO 14025:2006, ISO 14040:2006, and ISO 14044:2006).
After completing all necessary sections, contractors shall certify that they have met the minimum requirements by signing the 'EPD Construction Submittal' and 'Final Sign-Off' tables. Agency and Institution of Higher Education (IHE) Delegates shall review the tables for accuracy and completion. After all entries are reviewed and complete, the Agency/IHE delegate shall certify that they have met the minimum requirements by signing the 'EPD Design Submittal', 'EPD Construction Submittal', and 'Final Sign-Off' tables before submitting this spreadsheet and the EPD zip folder to the OSA as part of the Project Close Out Code Compliance Documentation Exhibit L-1 (SBP-L-1).
