ConstructConnect vs BidNet vs SAM.gov — or a Service That Does It for You?
Side by side
ConstructConnect
What it is: A subscription database of commercial construction projects and bid opportunities, mostly private-sector work.
What it does well: Wide project coverage and plan access across many markets.
What’s left on your plate: You still search, filter, read every package and reach out to GCs yourself.
BidNet Direct
What it is: A service that collects government bid solicitations, largely from state and local agencies.
What it does well: Public-sector opportunities gathered in one place with alerts.
What’s left on your plate: Public bids come with their own forms, bonding and deadlines — someone still has to read and decide.
SAM.gov
What it is: The U.S. government’s free official site for federal registration and federal contract opportunities.
What it does well: The source of record for federal work; registration is required to bid federal contracts.
What’s left on your plate: Searching and reading federal solicitations is time-consuming and many aren’t a fit for a trade sub.
The Bid Engine
What it is: A 90-day done-with-you program. We pull from sources like these, add GC bid-list outreach, filter for your trade and area, and screen every invite.
What it does well: Every invite screened within one business day with a one-page go/no-go summary, plus rebuilt cost numbers.
What’s left on your plate: You do your own estimating on the jobs worth pricing. Limited spots per trade per market.

When a platform subscription is enough
If you have an estimator or office staff with time to search every day, read packages and chase GCs, a platform is a solid tool.
When you need more than a list
If you’re the owner, you’re running crews all day, and bid packages sit unread until it’s too late, more leads won’t fix it. What fixes it is someone getting you on more GC bid lists, filtering out what isn’t your trade or area, and telling you in plain English whether each invite is worth pricing. That’s what we do.
