7.3 Provide Cross Sections and/or 3D Models to Contractors – For Information only

Contractor access to construction cross sections and/or 3D models in electronic format allows the contractor to prepare more accurate and concise bids, particularly on projects with significant earthwork items.
Provide cross sections and/or 3D models online for contractor information for all geometric projects as directed by the department. Cross sections and/or 3D models produced from current design software are to be posted online for early contractor review, without modification.
Cross sections do not need to be signed and sealed.
The TxDOT project manager is responsible for ensuring the cross-sections and/or 3D models are posted by the appropriate time on the District’s centralized ftp site in the project folder with other pre-letting documentation. The files should be labeled as directed by the department.
Consultant engineering firms involved in TxDOT design projects must include this data as part of their deliverable to the District.
The following disclaimer must be included in the transmittal of the cross section data:
“The following data is for non-construction purposes, only. It is the responsibility of prospective bidder to validate the data.”
“Texas Department of Transportation”
If construction cross section data is provided directly in the plans, that data must also be clearly labeled “FOR INFORMATION PURPOSES, ONLY”.
For each monthly cycle, cross sections and/or 3D models are to be posted on or before the date advertisements are published in the Electronic State Business Daily (ESBD) according to the
PS&E Review and Processing Schedule
