Kahua vs. e-Builder: Compare Construction PM Software

If you’re choosing a construction PMIS for your long-term capital program, a surface-level feature comparison won’t tell you enough.

Kahua and e-Builder are a good example. (e-Builder Enterprise is now Trimble Unity Construct. Trimble says existing projects, documents, processes, integrations, APIs, and core functionality remained intact through the change.)

Because many construction teams still know the platform as e-Builder, we’ll use that name where helpful. However, this comparison evaluates the capabilities Trimble offers today.

Both platforms are credible enterprise options for complex capital programs. The more useful questions begin when your requirements become more specific:

• How easily can the platform change when your processes change?
• Can different programs follow different workflows without making portfolio reporting harder?
• What happens when information crosses from an owner to a GC, designer, consultant, or subcontractor?
• Can your team create new applications when requirements change?
• How does AI fit into the work your teams already do?
• What happens to project and asset information once construction ends?

Those questions reveal where the platforms begin to diverge.

Kahua vs. e-Builder at a glance

The table below shows where their operating models start to differ.

Kahua

Best for: Owners and delivery teams that need their construction platform to adapt across different programs, project types, business processes, and organizations.

Kahua is an AI enterprise construction platform that connects work from planning and funding through project delivery, portfolio reporting, and asset handover.

You can establish common standards across your organization without forcing every project to operate the same way. A healthcare renovation, roadway program, school bond project, and commercial development may require different approvals, records, funding structures, or reporting.

Kahua can preserve those differences while still giving leadership a consistent view across the portfolio. Its configurable architecture extends beyond standard forms to the applications and workflows themselves.

Key strengths

• Applications and workflows that fit your processes: kBuilder Canvas extends Kahua’s configuration model, allowing teams to create and revise applications and workflows using natural-language input.
• Capital planning and funding: Kahua connects long-range planning with Sources of Funds, giving you a way to manage grants, bonds, appropriations, reserves, releases, budgets, commitments, invoices, and actuals.
• Portfolio structures that reflect your organization: Portfolio Management lets you group projects by region, business unit, project type, or another structure while maintaining roll-up visibility.
• Cross-company collaboration: The Kahua Network connects information and workflows across owners, GCs, subcontractors, consultants, and other participants while helping each organization retain control of its own records.
• AI within the construction platform: Kahua AI includes Noa, which integrates with the workflows and information already in Kahua.
• Integration with the rest of your technology stack: Kahua supports open APIs and integrations with ERP, accounting, scheduling, design, and other construction systems.
• Construction information that remains useful after closeout: Asset Centric Project Management captures asset information throughout delivery so operations teams don’t have to reconstruct it at handover.

Things to consider

Kahua’s configurability is most valuable when you know where your organization needs consistency and where it needs flexibility. 

Before implementation, define data standards, permissions, reporting requirements, and which workflows can vary across projects.

Complex configurations and integrations also require planning. If you only need a narrow tool for simple project workflows, you may not need the full depth of an enterprise construction platform.

e-Builder / Trimble Unity Construct

Best for: Owners managing structured capital improvement programs, particularly organizations that want an owner-centered PMIS or already work within the Trimble ecosystem.

e-Builder has a long history in owner-focused capital program management. Today, the platform is offered as Trimble Unity Construct, which Trimble describes as the next evolution of e-Builder.

Unity Construct provides owners with a centralized environment for capital planning, funding allocation, bidding, workflows, schedules, documents, project costs, reporting, and asset handover. Its business process tools can standardize reviews and approvals, while configurable dashboards let teams drill down from program-level information to the underlying project details.

Owners can also collaborate with general contractors, architects, engineers, and other participants while maintaining centralized visibility into project costs, schedules, documents, and processes.

Its place within the larger Trimble ecosystem is another important part of the current product story. Unity Construct focuses on capital programs and construction, while other Trimble products extend into enterprise asset management, permitting, field operations, GIS, and common data environments.

Key strengths

• Owner-centered capital program management: Unity Construct is designed specifically around the planning, delivery, and oversight requirements of asset and facility owners.
• Capital planning and funding allocation: Owners can prioritize projects, manage approvals, assess cash flow needs and allocate capital across the program.
• Business process automation: Configurable forms and structured workflows can standardize approvals, enforce organizational processes, and maintain clearer records.
• Cost and schedule control: Financial and schedule information can remain connected to the larger project record.
• Program reporting: Configurable dashboards and reports provide visibility into projects and portfolios, with drill-down capabilities.
• Document and project controls: Centralized records can help owners manage documentation across contractors and consultants.
• API access: The Unity Construct API supports reading, writing, and updating information, allowing organizations to synchronize data with other tools.
• Connection to the broader Trimble ecosystem: Unity Construct can work alongside Trimble Unity Maintain, Permit, Field, and Trimble Connect as owners extend their digital processes beyond construction.

Things to consider

If you’re evaluating Unity Construct, map your requirements across the entire Trimble Unity suite. Some asset management, field, permitting, and common data environment capabilities are offered in separate products rather than within Unity Construct itself.

You should also compare the type of configuration you expect to need. Unity Construct supports configurable forms and business processes. If your organization expects to create entirely new applications or frequently redesign how information and workflows work across different programs, compare that model closely with Kahua’s application-building approach.

Key differences between Kahua and e-Builder

The more meaningful differences appear in how the platforms handle configuration, financial governance, collaboration, AI, and the transition from construction into operations.

Application configurability and workflow design

Both Kahua and Trimble Unity Construct support configuration, so this isn’t a question of whether either platform can accommodate established business processes.

Unity Construct provides business process automation that lets owners standardize workflows, approvals, forms, and project controls. That can be especially useful when you want consistent processes across a capital program.

Kahua extends configuration into the application layer. You can adapt existing applications or create new ones around requirements that aren’t covered by an out-of-the-box process.

kBuilder Canvas adds AI-assisted creation to that model. You can describe an application or workflow in natural language, generate a working version, review the design, adjust fields and rules, and refine it before deployment. At the time of writing, kBuilder Canvas is available through Kahua’s Early Access program.

That distinction becomes important when your requirements extend beyond modifying an existing workflow. A transportation program may need a specialized right-of-way application. A GC may need different approvals, reporting, and processes across clients. A new regulation may introduce records that the current configuration doesn’t capture.

If your primary goal is to standardize and automate established owner workflows, Unity Construct has tools designed for that purpose. If you expect to create new applications or accommodate substantially different processes over time, Kahua offers a broader application-building model.

Capital planning, funding, and cost management

Both platforms have substantial capabilities for capital planning and financial control.

Trimble Unity Construct supports capital planning, project prioritization, funding allocation, cash flow requirements, and project cost management. Its owner-centered structure helps connect investment decisions with the projects those investments support.

Kahua also connects capital planning with project and program financials. Its Sources of Funds capability adds detailed controls for organizations managing multiple funding sources.

You can define grants, bonds, appropriations, reserves, and other sources, and then assign dates, amounts, release schedules, and consumption rules. Those funds can connect directly to budgets, commitments, invoices, and actuals.

That level of traceability becomes particularly useful when a project doesn’t have a single budget.

A grant may apply only to certain expenses. Bond proceeds may be restricted to specific projects. Appropriations may arrive in stages. One funding source may need to be consumed before another. Your finance and program teams may need to see what is reserved, released, committed, spent, and still available across an entire portfolio.

Twin Rivers Unified School District faced that challenge while managing local, state, and federal funding across its facilities program. Before Kahua, staff reconciled information across multiple systems and spreadsheets. With Sources of Funds and Kahua Analytics, the district replaced 28 spreadsheets with a more current view of budgets, commitments, and balances.

Read the Twin Rivers School District case study for the full story.

When comparing Kahua vs. e-Builder for financial management, test your real funding model in both systems. Look beyond whether each platform tracks costs and ask how it handles your funding rules, releases, approvals, exceptions, and reporting requirements.

 Portfolio visibility and reporting

Both platforms provide visibility beyond individual projects.

Trimble Unity Construct provides owners with project and program reporting, dashboards, and visibility into budgets, changes, schedules, and program performance.

Kahua’s Portfolio Management is designed to let organizations structure that visibility around the way they actually operate. You can group projects by business unit, region, project type, or another custom hierarchy, then move from a portfolio view into the program, project, or record behind it.

Different portfolios and project types can also follow their own workflows, templates, and reporting rules without forcing every team into the same process.

The practical question, then, isn’t whether either product has dashboards. Ask how easily your information can move from different project structures into reporting that leadership trusts:

• Can different project types still roll up into a consistent portfolio view?
• Can leaders move from a portfolio-level risk or cost indicator to the underlying records?
• How much manual reconciliation is required before an executive report is ready?
• Can reporting evolve when leadership starts asking different questions?

The better fit depends on how standardized your underlying projects are and how much variation your portfolio needs to support.

Collaboration and data control across organizations

Capital projects rarely remain within a single company. Owners work with GCs. GCs work across multiple owners. Designers, subcontractors, consultants, inspectors, and other partners all create and exchange project information.

Trimble Unity Construct approaches collaboration from the owner’s perspective. It provides a centralized environment where owners can coordinate with general contractors, architects, engineers, and other project participants while maintaining visibility into project costs, schedules, documents, and processes.

Kahua takes a different approach through The Kahua Network.

The Kahua Network lets organizations share documents, records, approvals, and workflows across company boundaries without requiring every participant to be in the same organizational workspace. Each company can retain control of its own data and processes while giving project partners access to the information they need.

That distinction can become important as project teams change.

An owner may work with several contractors across a capital program. A GC may work for multiple owners simultaneously. Designers and subcontractors may move between projects while maintaining their own records, workflows, and reporting obligations.

The collaboration model also influences which organizations can use the platform as more than a participant in someone else’s system.

Unity Construct is explicitly designed around owner-led capital programs. Kahua has a strong owner foundation but also supports general contractors and other delivery organizations running their own projects, portfolios, processes, and integrations.

If your environment is primarily owner-centered, Unity Construct’s model may fit naturally. If several organizations need to collaborate while maintaining their own operating environments and data controls, Kahua’s network model deserves closer consideration.

AI and platform administration

AI is becoming part of construction software evaluations, but comparing AI by the number of features or assistants doesn’t tell you much.

A better set of questions is:

• What project information can the AI access?
• What actions can it take?
• Does it work inside existing permissions and workflows?
• Can users review what it creates before it goes live?
• How much administration or specialist development does it remove?

Trimble continues to invest in AI, analytics, automation, and connected data across its broader technology portfolio. Unity Construct also uses digital workflows and connected project information to automate and manage capital-program processes.

Kahua embeds AI directly into the construction platform through Noa, powered by Kahua AI.

Noa works within the Kahua environment and its existing workflows, access controls, and project information. Noa Assists can help users find project information, create records, and reduce repetitive tasks. Noa Creates works with kBuilder Canvas to turn natural-language instructions into applications and workflows.

That makes Kahua’s AI story particularly relevant when AI can reduce administrative effort inside the system of record, rather than functioning as a separate assistant alongside it.

Asset lifecycle and handover

Both Kahua and Trimble recognize that project information should remain useful after construction ends.

Trimble Unity Construct supports asset handover as part of capital project delivery. Trimble extends that model across its broader Unity suite. Unity Maintain supports enterprise asset management and maintenance, while Unity Field adds mobile field capabilities. Trimble Connect provides a common data environment for construction information.

That can be attractive if your technology strategy spans multiple products across the Trimble ecosystem.

Kahua takes an Asset Centric Project Management approach. Teams can collect operationally useful asset information during planning, design, and construction rather than rebuilding it at closeout. That can include serial numbers, warranties, documents, and other records associated with installed assets.

The resulting owner-controlled asset information can then connect with BIM, GIS, enterprise asset management, computerized maintenance management, and other operational systems.

The right approach depends on your technology strategy.

If you want construction, maintenance, GIS, permitting, and field activity to operate within a broader Trimble ecosystem, Unity offers that path.

If you already have operational systems and want construction to produce structured, owner-controlled asset information that can feed those systems, Kahua may align more closely with your environment.

How to choose between Kahua and e-Builder

If you’re comparing Kahua vs. eBuilder, don’t make the decision by adding up feature checkmarks.

Both products can support sophisticated capital programs. The more useful question is which platform best fits your organization’s needs for governing work, collaborating with external teams, and responding to changing requirements.

Choose Kahua if you need:

• Application-level configurability: You need to create new applications and processes, not only modify standard workflows.
• Variation across projects and programs: Different regions, clients, project types, or delivery models require different workflows while leadership still needs consistent portfolio visibility.
• Collaboration across independent organizations: Owners, GCs, subcontractors, consultants, and other participants need to share information while retaining control of their own data and processes.
• Detailed funding governance: Grants, bonds, appropriations, releases, reserves, and consumption rules need to remain tied to actual project finances.
• AI inside the construction system of record: You want AI to work with project information and workflows within the platform’s existing governance model.
• Connections to existing operational systems: You want structured asset information from construction to flow into the EAM, CMMS, BIM, GIS, or other systems your organization already uses.

Choose e-Builder / Trimble Unity Construct if you need:

• An owner-centered capital program environment: Your primary requirement is to provide the owner with a centralized system to plan and deliver capital improvements.
• Structured capital planning and funding allocation: You need established workflows for prioritizing projects, approving investment, managing cash flow, and allocating program funds.
• Standardized business processes: Configurable forms and workflows need to support consistent reviews, approvals, and organizational controls.
• Centralized project controls: Cost, schedule, documents, and program reporting need to operate within the owner’s environment.
• A broader Trimble technology strategy: Your organization wants construction, GIS, permitting, field activity, maintenance, or asset management connected through the wider Trimble ecosystem.
• Owner-led handover into Trimble asset management: Your longer-term plan includes Unity Maintain or other Trimble lifecycle products.

Once you have a shortlist, test both platforms against the same difficult scenarios.

Choose Kahua when your PMIS needs to adapt with your program

A PMIS decision has to last beyond the requirements you have today.

Your funding model may change. New project types may be added to the portfolio. Different contractors and consultants may join the program. Reporting requirements may evolve. Your teams may identify processes worth automating that weren’t part of the original implementation.

The question is whether your platform can accommodate those changes while preserving the governance, data quality, and visibility you depend on.

That’s where Kahua stands out in this comparison.

Kahua provides a governed foundation for capital programs while enabling applications, workflows, portfolio structures, and cross-company collaboration to adapt to how your organization works.

The Pennsylvania Turnpike Commission provides a practical example. When PTC evaluated a new project management and collaboration platform, it identified Kahua’s ability to build custom applications that conform to its business processes as a key differentiator.

FAQ: Kahua vs. e-Builder

Which is better, Kahua or eBuilder?

Neither platform is better for every organization.

Trimble Unity Construct, formerly e-Builder, is a strong option for owners who want an owner-centered platform for capital planning, funding, project controls, standardized workflows, reporting, and handover.

Kahua is generally the stronger fit when you need greater application-level configurability, collaboration across independent organizations, detailed funding controls, and AI that operates within the construction platform.

The right choice depends on which operating model better reflects your programs and project teams.

Is e-Builder now Trimble Unity Construct?

Yes. Trimble renamed e-Builder to Trimble Unity Construct in August 2025.

The change did not require existing customers to migrate their e-Builder data. Trimble said existing projects, documents, processes, integrations, APIs, and core functionality would remain intact. Unity Construct now sits within the larger Trimble Unity asset lifecycle suite.

You may still see e-Builder terminology in URLs, technical objects, older documentation, and construction-industry discussions.

How are Kahua and e-Builder similar?

Kahua and Trimble Unity Construct both support complex capital programs.

Their overlapping capabilities include capital planning, funding, cost management, project and program controls, documents, workflow automation, reporting, collaboration, integrations, and project handover.

The more meaningful differences are how each platform handles application configuration, cross-company data, AI, portfolio structures, and lifecycle information.

Which is more configurable, Kahua or e-Builder?

Both platforms support configuration.

Trimble Unity Construct lets owners configure business processes, forms, data, reporting, and approval workflows.

Kahua extends configuration into application creation. Teams can modify existing applications or create new ones around organization-specific requirements. kBuilder Canvas also uses natural language and AI to help create and refine applications and workflows.

If you mainly need to standardize established owner processes, both platforms deserve consideration. If you expect to create new applications as requirements evolve, Kahua offers a broader application-building model.

How do Kahua and e-Builder compare for capital planning and funding?

Both provide capital planning and financial controls for capital programs.

Trimble Unity Construct supports project prioritization, funding allocation, cash flow planning, and cost management.

Kahua connects capital planning with Sources of Funds, where grants, bonds, appropriations, reserves, releases, and configurable funding rules can be tied to budgets, commitments, invoices, and actuals.

If your organization manages complex or restricted funding, test those actual funding scenarios in both platforms rather than comparing feature names alone.

Is Kahua or e-Builder better for general contractors?

Trimble Unity Construct is primarily designed around the owner’s capital program. General contractors, architects, engineers, and other partners can collaborate within that environment.

Kahua also supports owner programs, but general contractors can use the platform for their own workflows, portfolios, integrations, and data while collaborating across client and subcontractor relationships.

That can make Kahua a stronger candidate when a GC needs a construction platform it can use across different owners, clients, and project types.

Explore Kahua for general contractors for a closer look at those workflows.

What should you compare before replacing e-Builder?

Start with the processes that create the most work or impose the most constraints today.

Compare how each platform handles application and workflow changes, funding rules, portfolio reporting, outside collaborators, integrations, AI governance, asset handover, administration, and implementation.

Then test those capabilities against your own projects.

Replacing e-Builder should solve a specific operating problem. Moving the same processes into a different interface without addressing the underlying problem is unlikely to deliver the value you’re looking for.
