Get support for your bid on County solicitations with resources for vendors.

If you’re a vendor preparing to bid on a County contract, we want you to be successful. Learn about our support programs below.

Read the Solicitation & Ask for Help

The most important resource is the solicitation document itself; please read carefully.

Each solicitation includes a contract-specific “Calendar of Events.” Consult this Calendar for key dates, including Bidders Conferences/Pre-bid Events, submission deadlines and award announcement dates.

Do not hesitate to contact the point of contact listed on your bid documents if you have questions.

Submit a Bid: Dos & Don’ts. Avoid common mistakes when preparing your bid.

Vendor Outreach: Goods & Services

Vendors of goods and services who are interested in responding to County solicitations are encouraged to attend our weekly Vendor Outreach Events.

Vendor Outreach
Every Wednesday, 10:30-11:30 a.m.
Location: see Upcoming Events for location for your preferred date.
During COVID, all Vendor Outreach events will be held online.

Vendor Outreach events are not specific to any single project. Everyone is welcome.

Bidders Conferences/Pre-Bid Events

For all formal bids, the County hosts a:

  • Bidders Conference (Goods & Services) — usually optional
  • Pre-bid Event (Construction) — usually mandatory

Bidders Conferences and Pre-bid Events are specific to each solicitation and give vendors the opportunity to ask questions about the contract and the bid process.

In most cases, these questions and the answers are then issued as a Q&A document, available to the public. We may also issue addenda following conferences/events. Consult your solicitation document for key dates.

Small, Local and Emerging Businesses and smaller vendors are encouraged to attend these events to have the opportunity to meet vendors who are looking for subcontracting partners.

Small, Local & Emerging Business (SLEB)

To promote the diversity and strength of our local economy, the County has created requirements and incentives for SLEBs, and larger contractors working with SLEBs.
