Join

Join is preconstruction and design-phase software that gives owners, designers, and contractors one shared workspace to align scope, cost, schedule, and risk while design is still evolving.

Join focuses on the window before shovel-ready documents are frozen: owners, architects, engineers, and builders need shared visibility as drawings and options change. The product describes itself as a system of record for preconstruction and the design phase, combining cost and schedule context with design evolution so decisions are easier to defend later.

Public marketing claims include more than one thousand customer companies and more than ten billion dollars in tracked decision impact, plus more than one thousand projects referenced in customer proof points. Those figures are useful for sizing vendor traction but should not replace your own internal metrics on a pilot (Join website, 2026).

Join explicitly names collaborative delivery models such as design-build, CMAR, IPD, IFOA, and target value design as supported contexts. Feature themes include scenario modeling, risk and contingency governance, and visual alignment between schedule and budget.

The company states it was founded in 2017 and mixes construction operator experience with technology backgrounds. Pricing is not published on the landing page, which typically indicates enterprise sales and negotiated agreements (Join website, 2026).

Pros and cons

Pros

  • Strong positioning for early-phase alignment before late-stage change orders pile up.
  • Public social proof with named large contractors and clear quantitative claims.
  • Explicit support language for integrated forms of agreement and target value approaches.

Cons

  • No transparent pricing on the main marketing site; expect demos and procurement cycles.
  • Depth of integration with your authoring tools and ERP should be validated on your stack.
  • AI-enabled features are mentioned at a high level; ask what is generally available versus roadmap.

Key features

  • Decision record for preconstruction: Centralizes decisions so teams can see what changed, why, and who agreed as design moves.

  • Cost and schedule intelligence: Connects budget and timeline views so trade-offs are visible while options are still open.

  • Scenario modeling: Supports comparing alternatives before commitments harden into contract scope.

  • Risk and contingency governance: Surfaces contingency use and risk drivers while design is still flexible.

  • Collaborative delivery alignment: Messaging references design-build, CMAR, IPD, IFOA, and target value design workflows.

Frequently asked questions

What does Join software do?

Join provides a shared workspace for preconstruction and the design phase so owners, design teams, and builders can align cost, schedule, and risk while design evolves. It is positioned as a decision system of record rather than only a drawing viewer.

Is Join only for design-build projects?

No. The site calls out design-build explicitly, but it also references CMAR, IPD, IFOA, and target value design. Ask the vendor how workflows map to your contract type.

How much does Join cost?

The public homepage does not list standard per-seat prices. Expect enterprise pricing after scoping company size, project volume, and required integrations.

Does Join replace my estimating software?

Join is framed around decision alignment and visibility across cost, schedule, and design change. Whether it replaces or complements your estimating stack depends on integrations and how your precon team works today.

Can owners use Join without giving contractors full financial detail?

The marketing story emphasizes transparency across stakeholders, but real permissions models depend on your configuration and contract. This should be covered during security and governance review.

What should I prepare before a Join demo?

Bring a recent project where late design changes hurt cost or schedule, plus a list of systems of record you must connect, such as ERP, CDE, and scheduling tools.
