Integrated Project Delivery (IPD)
Owner, architect, and contractor sign one contract and share the project's financial outcome.
Quick Answer
Integrated Project Delivery (IPD) is a delivery method where the owner, architect, and contractor sign a single multi-party contract and share financial risk and reward on the project. Key trade partners often join the agreement too. Unlike CM at Risk or design-bid-build, no party can shift blame or profit at another's expense — the whole team wins or loses together.
The Full Picture
IPD exists as a response to the adversarial default of traditional delivery: separate contracts between owner-architect and owner-contractor create separate interests, so disputes and finger-pointing over cost and scope are structurally built in. IPD tries to remove that by making the parties' financial outcomes the same thing.
Mechanically, the core team signs one relational agreement that pools each firm's profit and, on many projects, overhead, into a shared pool tied to project performance. Decisions are made jointly and early, often with major trade contractors brought in during design, and cost and risk are managed collaboratively against a shared target cost rather than negotiated between separate contracts.
In practice, IPD looks different from a typical project: the owner, architect, structural and MEP engineers, and key trade contractors sit in the same room from early design, working toward a jointly developed target cost. Big-room or "cluster" collaboration sessions and shared BIM models are common tools, though IPD is defined by the contract structure, not by any specific software.
The commitment IPD asks for is real — waived liability between signatories and pooled profit require a level of trust most owners and firms haven't built with each other before, which is why IPD remains far less common than CM at Risk or design-bid-build despite strong results where it's used well.
Real Examples
Common Misconceptions
People assume: IPD just means everyone collaborates closely.
Actually: Close collaboration can happen on any delivery method. IPD specifically means a shared multi-party contract with pooled financial risk and reward — the legal structure, not just the working style, is what defines it.
People assume: IPD and design-build are basically the same thing.
Actually: Design-build puts design and construction under a single responsible entity contracted to the owner. IPD keeps the firms separate but binds them into one shared agreement and shared outcome — a different legal relationship, not just a naming difference.
Does MeltPlan Solve This?
Partially — adjacentMeltPlan doesn't structure or administer the multi-party IPD agreement itself — that's a legal and contractual decision for the team. But the design review and coordination work IPD teams rely on during early collaboration still needs doing: MeltPlan's AI reviews drawings and specs for coordination issues between disciplines, which fits naturally into IPD's early, shared-document workflow.

What makes IPD different from other delivery methods?
The single multi-party contract and shared risk/reward pool. In CM at Risk or design-build, each firm still has its own separate profit at stake; in IPD, the signing firms' financial outcomes are tied together against a shared target cost.
Who signs an IPD contract?
At minimum the owner, architect, and contractor. Many IPD agreements also add key trade contractors — commonly structural, mechanical, and electrical — as signatories once they're selected, so the people doing the coordinating are also sharing the outcome.
What are the downsides of IPD?
It requires a level of trust and cultural readiness many teams haven't built, waived liability between signatories can be a hard sell for legal and insurance teams, and it's less standardized than CM at Risk or design-build, so fewer firms have run it before.
Why does IPD matter for preconstruction?
Preconstruction is where IPD's value shows up most — trade partners help set the target cost and flag constructability issues during design, when changes are still cheap, instead of after documents are finished and bid.
How common is IPD compared to CM at Risk?
Far less common. It's concentrated on complex, collaboration-heavy projects — healthcare, higher education, and some public work — where owners are willing to invest in the contractual and cultural setup it requires.
