How to Register on CivCast: Contractor Guide (2026)

What CivCast is

CivCast is a bid platform that civil engineering firms and public agencies use to advertise construction projects, distribute plans and specs, manage plan holders and addenda, and receive bids. The service is run by Amtek Information Service, Inc., which is named in CivCast's site footer and terms. CivCast's current website is civcast.com. Many agency bid notices still link to the older civcastusa.com address, so expect to see both.

For contractors, the first question is who pays. CivCast's pricing page describes per-project fees charged to the engineers and agencies that post work, and it states that contractors participate for free. Its homepage says contractors download plans and specs at no cost. The City of Corpus Christi, which posts its construction projects on CivCast, tells bidders that registration is required and services are free of charge.

The second question is who sets the rules. CivCast is the platform, but each project is controlled by its publisher: the agency, utility, district, or consulting engineer that posted it. The publisher decides whether bids are taken online, on paper, or both, which documents must be uploaded, whether the plan holder list is visible, and whether a project is public or invitation-only. CivCast's terms also state that it does not review or verify files uploaded by third parties, so the solicitation documents always govern. For a broader view of where public construction work is posted, see our guide to finding government construction bids.

Step 1 - Create your CivCast account

Start at civcast.com and choose Create Account in the top navigation. The site footer labels the same link Register, and both open the sign-up page in CivCast's web app at app.civcast.com. Returning users sign in through the Login link. CivCast does not publish a field-by-field list of what the sign-up form asks for, so follow the screens as they appear and verify current steps on the official portal.

Use a company email address that someone on your estimating team watches every day. Addenda notices, Q&A alerts, and project updates go to that address.

Decide early how your team will share access. CivCast's terms state that account credentials are personal to each user and must not be shared with any other person or service, so each estimator who downloads documents or submits bids should have a login of their own. CivCast lists multi-user account management among its electronic bidding features; verify on the official portal how users are linked to one company.

Step 2 - Complete your company profile

Fill in your company profile with the same legal name, address, phone, and contact person you use on bid forms. Treat it as a public record. CivCast's terms state that when you download plans or bid documents, you are added to the plan holders list for that bid and your contact information is available to the public. The terms also state that CivCast does not remove plan holders from plan holder lists, because publishers rely on an accurate record.

CivCast's bid management page lists company type and role designation, plus DBE certification tracking and display, among its plan holder list features. If the profile or project screens ask for your role, such as prime contractor, subcontractor, or supplier, or for certifications, answer accurately. Subcontractors and suppliers often use public plan holder lists to find the primes they want to quote.

Keep the profile current so new plan holder entries show the right estimating contact. Answer any field not described here from your company's records, and verify current steps on the official portal.

Step 3 - Set up project alerts and saved projects

Set up alerts so new projects in your trade and area come to you instead of you hunting for them. CivCast states that contractors get alerts when projects match their interests, and it lists keyword-based contractor alerts and automated project matching among its advertising features. CivCast also lets contractors bookmark projects as favorites so they can come back to them.

Build your keywords around how owners actually title civil and public works projects: scope words such as water line, lift station, paving, drainage, or wastewater treatment, plus the materials and agency names you pursue. CivCast does not publish step-by-step instructions for configuring alerts, so verify current settings on the official portal. Alerts are a starting point, not a bid calendar: put each project you plan to bid on your own internal list with its bid date, pre-bid meeting, and question deadline.

Step 4 - Find a project and review the listing

Use the Bids link on civcast.com to open CivCast's list of bid opportunities. CivCast lists keyword search, advanced search filters, date range and deadline searching, and geographic location filtering among its search tools. Each publisher also has a dedicated page showing all of its projects, which is useful when you track a specific city, county, utility, or engineering firm.

Read the project page before downloading anything. CivCast states that a listing can include the scope, dates, contacts, pre-bid and bid-opening details, and an estimate. Note how bids will be received (online, on paper, or both), whether there is a pre-bid meeting, and when questions close.

Some projects are not open to everyone. CivCast lists private project visibility and private bid access codes for invitation-only projects, so use the access instructions the owner gives you. CivCast also lets a publisher set the bid date to TBA, so watch for the actual date in a later update or addendum.

Step 5 - Download documents and join the plan holder list

Download the plans, specifications, and bid documents from the project page. CivCast states that contractors download plans and specs at no cost, and it organizes project files into categories such as Bid Documents, Plans, Addenda, and Plan Revisions.

Downloading is also how you join the plan holder list. CivCast's bid management page says plan holders are added automatically when they download documents, and that the publisher can also register plan holders manually. Publishers can see a download history showing which contractor downloaded which document and when. Download from your own login so the right company and contact are recorded and addenda notices reach the right person.

Some owners require their own vendor registration on top of CivCast. The City of Corpus Christi, for example, tells firms to register with the City through its Supplier Portal, with a W-9 required at the time of registration. Check the invitation to bid for any separate agency registration, and finish it well before bid day.

Step 6 - Track addenda and questions

Once you are a plan holder, watch the project page and your inbox for addenda and answers to questions. CivCast states that publishers can notify plan holders when they upload a document, and that the notify option is checked automatically for addenda. It also lists automatic bid date changes with notifications, so a new bid date can arrive through the same channel.

Questions usually go through the project's Q&A board. CivCast describes a central Q&A where an answer posted once is visible to all plan holders, with question deadlines enforced and email alerts that contractors can subscribe to for new questions and answers. The City of Corpus Christi states that all questions and answers will be addressed on the CivCast site along with the release of addenda and other documents.

Acknowledge every addendum. CivCast lists mandatory acknowledgment requirements for addenda, and on electronic bids it can block submission until addenda are acknowledged. In a 2025 City of San Antonio solicitation, the addendum told bidders to acknowledge it in CivCast when downloading it and stated that acknowledgment was required to submit a bid in CivCast.

How to find and submit a bid on CivCast

Whether a project takes online bids is the owner's choice. CivCast's pricing page sells electronic bidding to publishers as part of a per-project package, and CivCast states that owners can accept electronic and paper bids on the same project. The invitation to bid, not the platform, tells you how to deliver your bid. Some solicitations are online only: a 2025 City of San Antonio invitation said online bidding was through CivCast and that hard copies would not be accepted.

When a project accepts e-bids, CivCast describes an online bid form built by the owner. It can include multiple bid schedules, additive and replacement alternates, and unit prices set as fixed amounts, maximums, minimums, or percentages. CivCast states that bid totals update automatically as you type, that unit prices are validated, and that you cannot submit without the required documents and addenda acknowledgments. Owners can require specific downloads with acknowledgment tracking, document uploads such as a bid bond or certifications, and a disclaimer acknowledgment.

CivCast also lists progress saving for partly completed bids and deadline countdown timers. After you submit, CivCast states that bids are kept in an encrypted lockbox until opening, with time-stamped submission records. It lists a bid history where contractors can view their own submission status and timestamps, plus the ability to withdraw and resubmit a bid. Agency rules on withdrawal still apply, so read the solicitation.

Bid bonds and signatures follow the owner's rules. CivCast documents the bid bond as one of the files an owner can require you to upload, but it does not publicly document a built-in signing tool or an electronic surety bond service, so verify current steps on the official portal. Agency examples show how much this varies. The 2025 San Antonio invitation listed the bid bond among the required uploads in CivCast and required those documents to be fully completed with digital signatures. The City of Corpus Christi states that bid security in the form of a cashier's check cannot be accepted electronically.

After the deadline, CivCast states that the owner opens all bids with one click, gets automatic rankings from low to high and a tabulation, and can post results and tabulations to bidders. Owners can also block bidders, use pre-qualification, and restrict specific plan holders from submitting bids.
