Scientific Services Contract Information

The Transportation Code, Chapter 223, Subchapter D provides that TxDOT may use competitive sealed proposals to procure the services of archeologists, biologists, geologists, historians, or other technical experts to conduct environmental or cultural assessments for transportation projects. The procedures for procuring the services of technical experts are Subchapter F, Contracts for Scientific Services, 43 TAC §§9.80 – 9.88. These procedures are separate from other procedures TxDOT may use to contract for scientific services, including procedures outlined in 43 TAC §§9.30 – 9.43 for procuring environmental services in conjunction with engineering, architectural, and land surveying contracts.

In accordance with 43 TAC §§9.80 – 9.88, TxDOT will:

  • Publish a list of upcoming contracts for scientific services on TxDOT’s web page, and update this list quarterly.
  • Publish a notice of invitation inviting prospective providers to submit a letter of interest (LOI) requesting copies of individual requests for proposals (RFPs) as they become available. Notice of requests for LOIs will be published on TxDOT’s web page, in a newspaper, and if the contract is for more than $25,000, in the Electronic State Business Daily. The LOI is a simple statement of interest and a request to receive a copy of the RFP. RFPs also can be obtained by downloading from TxDOT’s web site or attending a pre-proposal conference, if one is held. If RFPs are obtained by downloading or attending a pre-proposal conference, prospective proposers must notify TxDOT of their interest in the RFP if they wish to receive clarifications or amendments to the RFP.

Prospective providers do not have to be precertified to receive an RFP or to be awarded a contract, but individual RFPs may contain mandatory or minimum provider qualifications which must be met for the proposal to be considered responsive.
