Zepth vs Kahua: Owner PMIS Comparison

Choose Kahua if your organisation is a U.S. federal or regulated public-sector owner where FedRAMP Moderate authorisation, highly configurable workflows or an established multi-stakeholder Kahua ecosystem are decisive. Choose Zepth if you are an owner or PMC looking for an AI-native common data environment that links project controls, procurement and CapEx management across a portfolio. Kahua is publicly positioned as a low-code collaborative construction programme and project management platform; Zepth is designed around an owner-side CDE with Zepth AI operating across Core, Vector and Edge.

Quick Answer — Zepth vs Kahua at a Glance

The central choice is not whether either platform can manage documents, contracts or project information. Both publicly describe those capabilities. The decision is how the platform structures information, how much configuration governance your PMO can sustain, and whether AI must operate across the project record rather than within individual workflows.

For an evaluation committee, the shortlist should therefore be tested against five questions: which security regime is mandatory, who owns the information model, how much bespoke workflow design is required, whether portfolio analytics need a consistent record, and what the AI must do after implementation.

Who Is Kahua Built For?

Kahua is built for organisations managing collaborative capital programmes and projects across several participant types. Its published solution areas include owners and programme managers, government owners, general contractors, construction managers, subcontractors and suppliers. Its owner and government pages describe capital planning, funding, compliance, cost management, project controls, contracts, change orders, documents, bidding and field communication.

That breadth matters where a programme office needs one environment for owners and delivery organisations, or where contractors and programme partners already work in Kahua. Kahua also provides an app marketplace in which Kahua and partners develop industry- and owner-specific applications, including workflows associated with transport departments and higher education.

Its low-code application platform is a genuine strength for institutions whose processes differ materially from a standard construction workflow. Teams can configure workflows, forms and data objects, while partners can build specialised applications. The committee should balance that flexibility against governance: every variation in fields, approval routes or object definitions has implications for portfolio reporting, support and future migration.

For U.S. federal agencies and other public bodies that require FedRAMP or a comparable regime, Kahua has a documented advantage in the evidence reviewed here. The FedRAMP Marketplace lists “Kahua for Government – PaaS – FedRAMP Authorized” at Moderate Impact level. That requirement may outweigh differences in architecture or AI capability.

Who Is Zepth Built For?

Zepth is built primarily for owners, developers, owner’s engineers, PMCs and enterprise PMOs managing multiple capital projects. Contractors, consultants and suppliers can participate as collaborators, but the owner retains the primary project and portfolio context.

The platform is organised around a common data environment. Zepth Core covers design and construction, including documents, quality and safety, site operations, project controls and risk management. Zepth Vector covers procurement, including tendering, contracts, vendors and three-way matching. Zepth Edge covers asset and financial management, including CapEx, budgets and MIS reporting. Zepth AI is the intelligence layer across those products, not a separate product.

This structure is relevant to an owner because the same project or portfolio record can connect a document to an RFI, a change, a risk, a commercial commitment and a budget position. ISO 19650-1:2018 defines a common data environment as the single source of information for a given project, used to collect, manage and disseminate approved project information. Zepth applies that principle to the owner’s delivery and financial view rather than treating each project-control area as an isolated destination.

The design is also intended for committees that want AI to work with project context. Zepth AI can review submittals and RFIs against drawings and specifications with a confidence score, draft RFI responses with cited references, compare tender bids line by line, match invoices against purchase orders and receipts, and flag risk early. A human remains responsible for sign-off on consequential actions.

Feature-by-Feature Comparison

Project Controls (cost, schedule, risk in one system)

Kahua’s published owner and government materials cover capital planning, budgeting, funding, cost management, contracts, commitments, change orders, payment applications, schedule milestone tracking and performance reporting. Risk and issue management appears in several owner and government case studies, although the public material does not consistently describe it as a dedicated named module.

Zepth Core brings project controls and risk management into the CDE, while Vector connects procurement and commercial commitments and Edge connects budgets and CapEx reporting. The practical evaluation question is whether a PMO can trace a cost movement or change order to the relevant contract, document, schedule exposure and risk register without creating a separate reconciliation process.

Ask both vendors to demonstrate one scenario: an RFI changes the design, creates a variation order, affects a milestone and changes the forecast. Evaluate the number of records that must be updated, the audit trail, the portfolio-level view and the approvals required.

AI & Automation Depth (AI-native agents vs workflow automation)

Kahua publicly emphasises a low-code application platform, advanced automation and data-driven insights. As of July 2026, the supplied research does not identify a dedicated Kahua product page or named generative AI agent layer operating across the platform. That is not evidence that Kahua has no AI capability; the depth and scope are simply not clearly documented publicly.

Zepth is more explicitly AI-native in its documented architecture. Zepth AI is designed over the unified CDE, allowing intelligence to read across documents, cost, schedule, procurement and risk. A document-level tool may classify or extract information. A system-level agent can use that information in context: for example, compare a contract clause with a change order, connect an RFI to a schedule activity, or identify a risk pattern across projects.

The right test is not whether a demo contains an AI button. Ask what sources the AI can inspect, whether it cites its references, how confidence is shown, which actions remain subject to human approval and how the result is recorded in the audit trail.

Document Management, RFIs & Submittals

Kahua publicly documents a central repository, version control, drawing and specification management, transmittals, RFIs, submittals, workflow routing, approvals and audit trails. Those capabilities make it a credible option for document control and multiparty project collaboration.

Zepth covers the same core workflow areas through its CDE, with the distinction that Zepth AI can review submittals and RFIs against drawings and specifications, return a confidence score and draft responses with cited references. The value to an owner is not simply faster filing. It is the ability to examine whether an incoming item has a commercial, schedule or risk consequence before an approval is signed.

A useful committee demonstration is a submittal that conflicts with a specification or drawing. Require the vendor to show the source references, confidence treatment, reviewer sign-off, revision history and links to affected project records.

Reporting, Dashboards & Portfolio Analytics

Kahua offers standard reports and dashboards, custom reporting through its configurable platform and integrations with BI tools. The supplied public evidence does not specify a definitive set of BI products. Its app and low-code model can support institution-specific reporting, provided the owner maintains consistent definitions and governance.

Zepth Edge is explicitly focused on owner CapEx, budgets and MIS reporting, while Core and Vector provide the project and procurement context behind those figures. This supports portfolio questions such as which projects have unresolved risks connected to forecast movement, or which procurement commitments are affecting a programme budget.

Configuration can create a governance issue in any low-code environment. If departments or partners create several versions of an RFI, change order or risk object, the labels may look consistent while the underlying fields differ. Ask for a demonstration of metric governance across regions, programmes and delivery partners, not only a polished single-project dashboard.

Implementation Time & Ease of Use

No independent, dated study in the supplied research establishes a reliable implementation-time comparison between Kahua and Zepth. A committee should reject unsupported promises of a fixed delivery period and assess the actual work programme instead.

Kahua’s implementation effort will be shaped by the number of custom applications, workflow variants, integrations, security roles and historical records to migrate. That configuration can produce a close fit for a specialised institution, but it requires decisions about ownership, change control and support.

Zepth’s owner-centric information model is intended to standardise portfolios while allowing configuration within platform guardrails. Its implementation still depends on the number of projects, data quality, integrations, modules and approval structures. In both cases, ease of use should be tested with a real project pack and the roles that will use it daily, including the PMO, commercial team, site team, finance and external collaborators.

Pricing Comparison (published ranges + what drives cost)

Kahua does not publish list pricing, bundles or user-tier prices. Its public website and demo flow use a contact-led process. Third-party listings reviewed in the dossier do not provide an official Kahua price, and anecdotal discussion-board figures are not reliable evidence.

Zepth pricing should also be confirmed through a discovery-led quotation rather than assumed from a public range. Cost will depend on factors such as the number of projects, portfolio scope, selected products, user and collaborator requirements, integrations, implementation and support. Zepth does not charge per seat or per collaborator and does not price on construction volume; the commercial proposal should still specify the included products, environments, services and support obligations.

Ask both vendors for a five-year total-cost view covering subscription, configuration, data migration, ERP and BI integrations, training, support, custom development and future governance. For Kahua, ask how low-code application changes are priced and maintained. For Zepth, ask how Core, Vector and Edge are scoped and how the CDE will be integrated with finance and reporting systems.

Integrations & Ecosystem (ERP, BIM, existing tool stack)

Kahua provides a partner ecosystem and app marketplace. Its public materials describe integrations and data exchange, while specific ERP and BI packs are not fully detailed in the supplied evidence. Kahua also supports BIM document and model management through integrations and partner applications, including references to Revit and BIM 360 in partner materials. Buyers should verify which connections are native, partner-delivered or services-led.

Zepth’s integration model is centred on the owner record across project controls, procurement and financial management. The relevant evaluation scope includes ERP systems such as SAP, Oracle and Dynamics, BIM tools, e-invoicing and corporate BI, connected through APIs or agreed integration patterns. The committee should test object ownership, synchronisation frequency, error handling, reconciliation and responsibility for maintaining mappings.

For either platform, ask whether the integration preserves relationships between projects, contracts, commitments, invoices, documents, budgets and assets. A dashboard that receives totals without those relationships may not answer the owner’s more difficult questions about cause, exposure and accountability.

What Real Switching From Kahua to Zepth Looks Like (migration path, data continuity)

Switching is a data and operating-model programme, not a simple software replacement. Structured records that can be exported through reporting, APIs or vendor support may include projects, contracts, change orders, payment applications, RFIs, submittals, issues and related documents. Drawings, specifications and correspondence can often be retrieved in bulk, subject to the current agreement and export method.

Custom low-code applications, bespoke forms, workflow logic, notification rules and some finely grained permissions do not usually map directly into a different information model. Some workflow history may also require treatment as an archive rather than a live process. Those items are not necessarily lost, but they may need to be redesigned, converted or retained outside the active system.

1. Inventory: catalogue Kahua objects, documents, metadata, permissions, integrations and active workflows.
2. Map: map standard records such as RFIs, submittals, contracts and change orders to the Zepth CDE and identify fields requiring normalisation.
3. Clean: remove duplicates, resolve naming inconsistencies and validate project, contract and financial identifiers.
4. Pilot: migrate a representative group of active projects and test approvals, reporting, documents and user roles.
5. Cut over: freeze an export snapshot, move active and near-term work, and retain Kahua in read-only or archive mode where contractually and financially feasible.

The continuity objective is not to reproduce every old screen. It is to preserve the evidence needed for commercial, contractual, compliance and operational decisions, while rebuilding active workflows around a consistent owner-side record. Require both vendors to provide a sample migration map and identify records that will remain archived rather than operational.

Which Platform Should You Choose? (decision framework by project type/size)

Choose Kahua if you are a U.S. government or regulated institutional owner with a FedRAMP requirement, need substantial low-code customisation, or value an existing Kahua ecosystem spanning owners, contractors and partners.

Choose Zepth if you are an owner-led PMO evaluating portfolio governance, cross-project analytics, AI-assisted review, integrated procurement and CapEx continuity. It is particularly relevant when the committee wants the project record to work across teams rather than function only as a system of record.

The final evaluation should use your own data: an active contract, a drawing set, an RFI, a submittal, a change order, a procurement package, an invoice and a portfolio report. Ask each platform to show the complete chain, including human approval and auditability. Book a tailored Zepth walkthrough on your real project data.
