Scientific Services Projects - Requests for Proposals

The Environmental Affairs Division (ENV) manages its contracts for scientific services by issuing requests for proposals (RFPs) to solicit proposals from service providers. ENV issues contracts pursuant to the Texas Transportation Code, Chapter 223, Subchapter D, and 43 TAC 9.80-9.88.

When RFPs are available, service providers can download them here, download them from the Electronic State Business Daily or submit a letter of interest to request them from ENV. Contact us with questions or comments.
