Construction bid platforms have proliferated in the last decade, and the terminology around them has become muddled. "Bidding platform," "lead platform," "procurement portal" — these terms are used interchangeably, but they describe fundamentally different tools serving different roles in the construction bidding process.
This guide breaks down three of the most referenced platforms: Dodge Construction Network, PlanHub, and PlanetBids. Understanding what each one does — and who it serves — prevents paying for the wrong tool and missing the workflow fit that makes a platform valuable. For background on how construction bids flow from RFP through award, see construction RFP.
The Three Platform Types (and Why They're Different)
Before comparing specific platforms, it helps to understand that these tools serve three distinct functions in the construction opportunity ecosystem:
**Project intelligence / lead platforms** (Dodge Construction Network) identify projects early — often before bid documents exist — so GCs can track upcoming work, build owner relationships, and plan preconstruction resource allocation. The value is early visibility.
**Bid invitation platforms** (PlanHub, BuildingConnected) connect GCs posting bid invitations with specialty contractors receiving them. The GC controls which subs get access to plans; the sub responds to invitations. The value is organized bid distribution and document access.
**Government procurement portals** (PlanetBids, BidSync, Periscope) are owner-operated platforms through which public agencies publish solicitations, receive sealed bids, and manage the formal procurement process. The value is access to public work in a single organized location.
These categories can overlap — some platforms do more than one thing — but understanding the primary function guides the evaluation.
Dodge Construction Network — Best for Commercial Project Intelligence
Dodge Construction Network is the most comprehensive commercial construction intelligence platform in the United States, tracking project activity from the planning and design phase through construction start.
**What it does:** Dodge monitors publicly available sources — permit filings, design firm announcements, news, government records — plus a network of 500+ field reporters who verify project data on the ground. The result is a database covering 636,000+ construction projects annually, with 7,382 reports published per day (Dodge Construction Network, "About," 2026). GCs use Dodge to identify projects that match their trade mix and geography months before a formal bid invitation is issued.
**Who it serves:** Primarily GCs and specialty contractors doing proactive business development. If your firm has a dedicated BD or preconstruction team that actively hunts for opportunities, Dodge is the tool that gives you early visibility so you can connect with owners and design teams before the project goes to competitive bid.
**Key features:**
- Project tracking from planning through construction start
- Filtering by project type, size, geography, owner type, and stage
- Architect and owner contact information for relationship development
- Bidding calendar alerts for projects entering bid phase
- Market analytics for planning resource allocation and forecasting pipeline
**Pricing:** Dodge is a premium platform. A multi-user national access subscription runs $45,000–$60,000 annually for a five-person team. Regional plans are available at lower price points (constructionbids.ai, "Dodge vs. ConstructConnect Comparison," 2026). Dodge has historically renewed contracts with significant annual price increases — 10–20% year-over-year increases are common — making it important to evaluate ROI against pipeline generated.
**Key limitation:** Dodge provides project intelligence, not bid invitations. A GC tracking a project on Dodge still needs to respond to the owner's bid process through whatever procurement channel the owner uses. Dodge is a top-of-funnel tool, not a bid submission mechanism.
**Best for:** Mid-to-large commercial GCs with dedicated preconstruction or business development staff who can systematically work the pipeline Dodge identifies. Less valuable for smaller firms without the capacity to do proactive outreach on early-stage projects.
PlanHub — Best Bid Invitation Platform for Specialty Contractors
PlanHub is a cloud-based bid management and invitation platform designed to connect GCs distributing bid invitations with specialty contractors responding to them.
**What it does:** GCs post projects to PlanHub, upload plan documents, and invite subcontractors from a vetted network. Subcontractors receive notifications, access plan documents, and submit bids or indicate whether they will bid. The platform provides a shared environment for document distribution, addenda management, and bid tracking (PlanHub, "Product Overview," 2026).
**Who it serves:** PlanHub serves two different users with different workflows. GCs use it as a bid distribution tool — a replacement for emailing PDFs and tracking responses in spreadsheets. Specialty contractors use it as a passive lead source — waiting to receive invitations from GCs they're connected with on the platform.
**Key features:**
- Plan document hosting and access control
- Bid invitation distribution to the PlanHub subcontractor network
- Addenda distribution with acknowledgment tracking
- Bid receipt and comparison (basic)
- Sub qualification and communication tools
**Pricing:** PlanHub offers a free tier for subcontractors viewing and responding to invitations. GC features for active bid management are subscription-based. The subcontractor network is PlanHub's primary acquisition channel — subs register free, GCs pay for the distribution and management workflow.
**Key limitation:** PlanHub is invitation-dependent. Subcontractors only see projects when a GC on the platform chooses to invite them. There is no independent project discovery — if a GC isn't using PlanHub, their projects don't appear. This makes PlanHub's value highly dependent on the penetration of GCs in your local market who actively use the platform. See how to send bid invitations to subcontractors for the full ITB workflow that platforms like PlanHub support.
**Best for:** Specialty contractors who work predominantly with GC networks on PlanHub in their market. Less valuable as a standalone lead source — most subs use it alongside BuildingConnected and direct GC relationships rather than as a primary business development channel.
PlanetBids — Best for Public Sector Procurement
PlanetBids is an eProcurement platform used by government agencies — municipalities, utilities, school districts, public universities, transportation agencies — to manage formal competitive bidding for public construction and services.
**What it does:** Public agencies use PlanetBids to publish solicitations (IFBs, RFPs, RFQs), distribute bid documents, manage the plan holders list, receive sealed electronic bids, and process awards. Contractors register on PlanetBids for each agency they want to bid with and receive alerts for solicitations in their trade category.
**Who it serves:** Contractors pursuing public sector work. PlanetBids is an owner-operated tool — agencies buy the platform to manage their procurement process, and contractors participate through the agency's PlanetBids instance. More than 500 government agencies use PlanetBids (PlanetBids, "Product Overview," 2026).
**Key features:**
- Sealed electronic bid submission with encrypted lock-box until bid opening
- Solicitation management for IFBs, RFPs, RFQs, and informal bids
- Plan document distribution and addenda management
- Online Q&A (questions and answers visible to all bidders)
- Subcontractor and diversity outreach compliance tracking
- Prequalification management for agencies that require it
**Pricing:** PlanetBids is free for contractors to register and receive solicitations. Agencies pay for the platform. This makes it one of the most cost-effective ways to access public work — registration is free, and the barrier is simply knowing which agencies use the platform and registering before their next relevant solicitation.
**Key limitation:** PlanetBids serves a fragmented user base — contractors register per agency, not on a single network. If you pursue public work with 10 agencies across a region, you may need to register on 10 separate PlanetBids instances. Navigation and document management varies by agency. Aggregator tools that pull solicitations from multiple portals (including PlanetBids-hosted agencies) can reduce this fragmentation.
**Best for:** Contractors active in the public sector — municipalities, utilities, school districts, public infrastructure — especially in markets where public agencies have standardized on PlanetBids for their procurement.
Head-to-Head Comparison
| Platform | Primary Function | Who Pays | Best For | Pricing Model |
|---|---|---|---|---|
| Dodge Construction Network | Project intelligence / lead gen | GC/sub | Commercial GCs with BD teams | Subscription ($45K+/yr) |
| PlanHub | Bid invitation distribution | GC (sub free) | Specialty contractors on GC networks | Free/sub tiers |
| PlanetBids | Public procurement portal | Agency (contractor free) | Public sector bidders | Free to register |
Which Platform Do You Need?
The right answer depends on your primary business model:
**Commercial private work, proactive business development:** Dodge Construction Network is the right investment if you have the team capacity to work early-stage leads. Without dedicated BD resources, the subscription cost is hard to justify.
**Specialty contractor work responding to GC invitations:** PlanHub (alongside BuildingConnected) is the relevant network. Register on both and make sure your profile is visible to GCs in your market. See bid management software for a broader comparison of bid distribution tools.
**Public sector and government work:** PlanetBids registration is free and essential for the agencies that use it. Research which agencies in your target geography use PlanetBids versus other portals (BidSync, BonFire, OpenGov) and register across all relevant platforms.
**Comprehensive pipeline management:** Most active GCs use multiple platforms — Dodge for early project intelligence, BuildingConnected or PlanHub for sub bid management, and relevant government portals for public work. Managing inbound opportunities across channels requires a bid/no-bid decision process to filter and prioritize before committing estimating resources.
After the Opportunity: From Bid Platform to Bid Leveling
Bid platforms solve the project discovery and bid distribution problem. But once subcontractor proposals come in — from whichever platform was used to distribute the ITB — GCs still need to level those bids: compare them line by line, normalize scope, and identify gaps and exclusions before committing to a GMP or hard bid number.
Melt Bid (https://www.meltplan.com/bid) is AI bid leveling software that handles the post-receipt step: reading sub proposals, mapping them against scope, flagging exclusions, and producing a normalized comparison. Paired with any of the above distribution platforms, Melt Bid closes the loop between bid receipt and subcontractor award.
FAQ
**Is Dodge Construction Network worth the cost?**
For commercial GCs with dedicated business development resources who can systematically follow up on early-stage project leads, Dodge delivers strong ROI by identifying projects months before they go to competitive bid. For smaller firms without BD capacity, the annual subscription cost is difficult to justify against the value captured.
**What is the difference between PlanHub and BuildingConnected?**
Both are bid invitation platforms connecting GCs and specialty contractors. BuildingConnected (now part of Autodesk Construction Cloud) has broader market penetration and a larger subcontractor network. PlanHub is a standalone alternative with a simpler interface and lower GC subscription cost. Many specialty contractors register on both to maximize coverage.
**Is PlanetBids the same as Planet Bids?**
Yes — PlanetBids (stylized as one word by the company) is the eProcurement platform used by public agencies. The informal shorthand "Planet Bids" refers to the same platform.
**Can I find both public and private work on Dodge?**
Dodge tracks both public and private commercial construction projects. For public work, Dodge identifies upcoming projects early — but the actual bid submission still happens through whatever procurement portal the agency uses (PlanetBids, BidSync, etc.). Dodge is a lead source, not a submission portal.
Conclusion
Dodge, PlanHub, and PlanetBids serve different stages and sectors of construction bidding. Understanding the distinction — project intelligence vs. bid distribution vs. government procurement portal — is the prerequisite for choosing the right platform for your workflow.
The mistake most firms make is expecting one platform to solve all three problems. A better approach: use the right tool for each function, manage your pipeline across platforms with a disciplined bid/no-bid filter, and invest in bid leveling rigor once the proposals arrive — because the quality of your scope analysis at that point determines whether the number you commit to actually holds.
