Public Notice
Attention contractors:
A free training class on the fundamentals of partnering on Caltrans construction projects is upcoming. See our flyer and the schedule of classes. Register online at www.jointctindustrytraining.com.Welcome to Office Engineer
New! We want to hear what you think of the Office Engineer page, how we're doing, and what we can do to improve our service to the contracting community. Drop us a note at our feedback page with your comments or suggestions. Suggestions can be anonymous, or if you'd like a response, leave an email address or telephone number and we'll get back to you.
One of the things you can weigh in on is whether you like to see advertised plans in PDF format, such as we're testing out with project 08-0C2204. We look forward to hearing from you.
We have a new service available to let smaller contractors advertise their services to larger contractors. We're calling the service "Opt-in". To use the service, simply click on the Opt In link next to any of our advertised projects.

From there, fill in your business name and contact information, along with your disadvantaged business status and services or materials offered. You will show up on the list when prime contractors search non-bidders looking for suppliers or quotes. Note that this service does not guarantee any work, but it's a new way to give much-needed exposure to some of the smaller contractors wanting to do business with Caltrans.
Our bid item search tool is now online! Search advertised projects by either bid item work description or by item code numbers. See which projects fit your criteria, then see lists of prime or subcontractors also holding plans for that project.
