Most asset-intensive operators discover at some point that they have two parallel asset worlds. One is the heavy industrial estate — plant, network, fleet — running on Maximo. The other is the corporate real estate and facilities estate — buildings, leases, space, capital projects, soft and hard FM — running on a separate IWMS, a separate facilities CMMS, a CAFM tool, or a stack of spreadsheets. Both are asset management. Both consume the same kinds of data. Neither is talking to the other.
IBM Maximo Real Estate and Facilities — the IWMS capability formerly known as TRIRIGA, now delivered on the MAS platform — is the part of the MAS suite that closes that gap. It runs the IWMS workflows for the real estate and facilities estate on the same platform that already runs Manage for the industrial estate.
This guide is for the head of real estate, head of facilities, head of corporate services or CIO who has been asked whether to move IWMS workloads onto MAS. It sets out what REF is, when it pays off, what readiness honestly looks like, and the questions that separate a credible supplier from a confident one.
What Real Estate and Facilities actually is
REF is the set of IWMS capabilities running on MAS. The functional domains are the ones an IWMS practitioner will recognise:
- Real estate management — lease administration (including IFRS 16 / ASC 842 lease accounting), portfolio analytics, transactions, occupancy and utilisation
- Capital projects — programme and project management for the corporate estate, including refurbishment, fit-out and new build
- Space planning and management — space inventory, allocations, charge-back, move/add/change
- Facilities operations — planned preventive maintenance for facilities, soft FM workflows, service requests, contractor management
- Sustainability and ESG reporting — energy, water, waste and emissions data captured against the estate, supporting GRESB, CDP and similar frameworks
The point of running this on MAS rather than on a stand-alone IWMS is that the asset record, the work record, the inventory record and the contractor record are the same records the rest of the operation already uses. The corporate facilities estate becomes part of the same operating picture as the industrial estate, not a parallel one.
When REF pays off
REF earns its licence quickly under a few conditions.
There is a credible consolidation case. Most operators considering REF have a Maximo footprint already, and an IWMS or CAFM footprint alongside it that is at end-of-life or end-of-contract. The case is consolidation onto one platform, one operations team, one upgrade path. If both estates are happy and well-served on separate platforms, the case is weaker.
Lease accounting and ESG reporting are first-class outcomes, not afterthoughts. REF earns much of its value from the lease accounting capability and from the ESG/sustainability reporting layer over the estate. If neither is a stated outcome, the buyer is paying for capability they are not going to use.
Soft FM and hard FM are inside the scope. REF earns more of its value as the scope widens to include planned preventive maintenance for facilities, contractor management and service-request workflows. Where the scope is “lease admin only,” the case is narrower and lighter-weight tools may be a better fit.
Manage is in good enough shape to be the spine. REF runs alongside Manage on MAS. If Manage itself is shaky, the right move is to fix that first. The detail on stabilising Manage is set out elsewhere on the site.
Readiness checklist
Before scoping REF in earnest:
- Is the real estate portfolio mapped — properties, leases, spaces, allocations — at the level the operator wants to manage to?
- Is the lease accounting requirement clear, with the relevant standard (IFRS 16 / ASC 842) named and the integration to the finance system understood?
- Is the facilities maintenance scope defined — soft FM only, hard FM, both?
- Is contractor management a stated requirement, with the relevant procurement and safety controls articulated?
- Is the sustainability and ESG reporting requirement defined, with the frameworks (GRESB, CDP, TCFD, internal targets) named and the data sources identified?
- Is the consolidation case quantified — what platform is being retired, what licence and operations cost is coming out, what one-off migration cost is going in?
If most of those answers are “no” or “we don’t know”, the next quarter is about readiness, not about REF.
Questions to ask a supplier
The following questions separate a credible REF supplier from a confident one.
On the consolidation case. “What does our IWMS-to-REF migration look like, in terms of data, configurations and reports we keep, and what we deliberately leave behind?” A credible answer is honest about what does not migrate cleanly and what should be redesigned rather than lifted across.
On lease accounting. “Walk us through how IFRS 16 / ASC 842 lease accounting is configured here, and how the journals reach our finance system.” A credible answer treats lease accounting as a precise, audited capability, not a generic configurable workflow.
On facilities maintenance. “How do soft FM and hard FM coexist here, and how do contractor work orders flow through the procurement and safety controls?” A credible answer talks about specific control points, not “configurable workflow.”
On reporting. “What does ESG reporting look like out of REF for our specific frameworks (GRESB / CDP / TCFD / our own targets)?” A credible answer connects estate data to the reporting paths the operator already uses.
On the user population. “What does the day-to-day experience look like for a lease administrator, a facilities planner and a contractor against this, and is it credibly better than what they have today?” A credible answer takes user experience seriously; an IWMS that the lease admin team will not adopt is not a consolidation, it is a parallel system in waiting.
On hosting and operations. “Who runs REF after go-live, on what platform, and how does it sit alongside Manage hosting?” A credible answer treats REF as part of the same operations platform as Manage. We host both on the same managed cloud — see managed Maximo and MAS hosting.
On exit. “If we deploy lease admin and facilities maintenance and stop, what do we have?” A credible answer leaves the operator with a working capability on the in-scope domains, not a stranded half of an IWMS.
The TRIRIGA point
Real Estate and Facilities is, in functional lineage, the IBM TRIRIGA capability brought onto the MAS platform. Buyers familiar with TRIRIGA will recognise the model — leases, capital projects, space, operations, sustainability. The relevant change for the buyer is platform: one MAS instance, one OpenShift estate, one operations team across REF and Manage, on the same upgrade cadence.
For operators with an existing TRIRIGA footprint, the migration question is real and the right answer is rarely a literal lift-and-shift. It is more often a deliberate redesign on REF, with a clear policy on what configurations and reports come across and what gets simplified. We have a view; the practical guidance is in our broader services and in conversation.
Sequencing inside the wider suite
REF is the natural Manage companion for any operator whose corporate real estate and facilities estate has its own sizable workload. It sits alongside Field Service Management (where the work is distributed in the field) and Health (where capex prioritisation across both estates becomes a single conversation). The wider picture lives on the MAS suite overview.
Closing position
Maximo Real Estate and Facilities pays off when there is a credible consolidation case, lease accounting and ESG reporting are first-class outcomes, soft and hard FM are inside scope, and Manage is solid enough to be the spine. The capability is mature — the underlying TRIRIGA lineage is decades old — and the platform consolidation onto MAS is what makes it the natural answer for operators already on Maximo.
